Description of the Proposed Change
Background
STANS Overview
STANS is OCC’s proprietary risk
management system for calculating
Clearing Member margin requirements.7
The STANS methodology utilizes largescale Monte Carlo simulations to
forecast price and volatility movements
in determining a Clearing Member’s
margin requirement.8 STANS margin
requirements are calculated at the
portfolio level of Clearing Member
accounts with positions in marginable
securities and consists of an estimate of
two primary components: A base
component and a stress test add-on
component. The base component is an
estimate of a 99% expected shortfall 9
over a two-day time horizon. The

7 See Securities Exchange Act Release No. 53322
(February 15, 2006), 71 FR 9403 (February 23, 2006)
(SR–OCC–2004–20). A detailed description of the
STANS methodology is available at https://
optionsclearing.com/risk-management/margins/.
8 See OCC Rule 601.
9 The expected shortfall component is established
as the estimated average of potential losses higher
than the 99% value at risk threshold. The term
‘‘value at risk’’ or ‘‘VaR’’ refers to a statistical
technique that, generally speaking, is used in risk
management to measure the potential risk of loss for
a given set of assets over a particular time horizon.

concentration/dependence stress test
charge is obtained by considering
increases in the expected margin
shortfall for an account that would
occur due to (i) market movements that
are especially large and/or in which
certain risk factors would exhibit perfect
or zero correlations rather than
correlations otherwise estimated using
historical data or (ii) extreme and
adverse idiosyncratic movements for
individual risk factors to which the
account is particularly exposed. The
STANS methodology is used to measure
the exposure of portfolios of options and
futures cleared by OCC and cash
instruments in margin collateral.10
The econometric models underlying
STANS currently incorporate a number
of risk factors. A ‘‘risk factor’’ within
OCC’s margin system is defined as a
product or attribute whose historical
data is used to estimate and simulate the
risk for an associated product. The
majority of risk factors utilized in the
STANS methodology are the returns on
individual equity securities; however, a
number of other risk factors may be
considered, including, among other
things, returns on implied volatility risk
factors.11
Current Implied Volatility Model in
STANS
Generally speaking, the implied
volatility of an option is a measure of
the expected future volatility of the
option’s underlying security at
expiration, which is reflected in the
current option premium in the market.
Using the Black-Scholes options pricing
model, the implied volatility is the
standard deviation of the underlying
asset price necessary to arrive at the
market price of an option of a given
strike, time to maturity, underlying asset
price and the current risk-free rate. In
effect, the implied volatility is
10 OCC notes that, pursuant to OCC Rule
601(e)(1), OCC also calculates initial margin
requirements for segregated futures accounts using
the Standard Portfolio Analysis of Risk Margin
Calculation System (‘‘SPAN’’). No changes are
proposed to OCC’s use of SPAN because the
proposed changes do not concern futures. See
Securities Exchange Act Release No. 72331 (June 5,
2014), 79 FR 33607 (June 11, 2014) (SR–OCC–2014–
13).
11 In December 2015, the Commission approved a
proposed rule change and issued a Notice of No
Objection to an advance notice filing by OCC to its
modify margin methodology by more broadly
incorporating variations in implied volatility within
STANS. See Securities Exchange Act Release No.
76781 (December 28, 2015), 81 FR 135 (January 4,
2016) (SR–OCC–2015–016) and Securities Exchange
Act Release No. 76548 (December 3, 2015), 80 FR
76602 (December 9, 2015) (SR–OCC–2015–804). As
discussed further below, implied volatility risk
factors in STANS are a set of chosen volatility pivot
points per product, depending on the tenor of the
option.

responsible for that portion of the
premium that cannot be explained by
the then-current intrinsic value of the
option (i.e., the difference between the
price of the underlying and the exercise
price of the option), discounted to
reflect its time value. OCC considers
variations in implied volatility within
STANS to ensure that the anticipated
cost of liquidating options positions in
an account recognizes the possibility
that implied volatility could change
during the two-business day liquidation
time horizon and lead to corresponding
changes in the market prices of the
options.
OCC models the variations in implied
volatility used to re-price options within
STANS for substantially all option
contracts 12 available to be cleared by
OCC that have a residual tenor 13 of less
than three years (‘‘Shorter Tenor
Options’’).14 To address variations in
implied volatility, OCC models a
volatility surface 15 for Shorter Tenor
Options by incorporating into the
econometric models underlying STANS
certain risk factors (i.e., implied
volatility pivot points) based on a range
of tenors and option deltas.16 Currently,
these implied volatility pivot points
consist of three tenors of one month,
three months and one year, and three
deltas of 0.25, 0.5, and 0.75, resulting in
nine implied volatility risk factors.
These pivot points are chosen such that
their combination allows the model to
capture changes in level, skew,
convexity and term structure of the
implied volatility surface. OCC uses a
12 OCC’s Implied Volatility Model excludes: (i)
Binary options, (ii) options on commodity futures,
(iii) options on U.S. Treasury securities, and (iv)
Asians and Cliquets. These relatively new products
were introduced as the implied volatility margin
methodology changes were in the process of being
completed by OCC, and OCC had de minimus open
interest in those options. OCC therefore did not
believe there was a substantive risk if those
products were excluded from the implied volatility
model. See id.
13 The ‘‘tenor’’ of an option is the amount of time
remaining to its expiration.
14 OCC also incorporates variations in implied
volatility as risk factors for certain options with
residual tenors of at least three years (‘‘Longer
Tenor Options’’); however, the proposed changes
described herein would not apply to OCC’s model
for Longer Tenor Options. See Securities Exchange
Act Release Nos. 68434 (December 14, 2012), 77 FR
57602 (December 19, 2012) (SR–OCC–2012–14);
70709 (October 18, 2013), 78 FR 63267 (October 23,
2013) (SR–OCC–2013–16).
15 The term ‘‘volatility surface’’ refers to a threedimensional graphed surface that represents the
implied volatility for possible tenors of the option
and the implied volatility of the option over those
tenors for the possible levels of ‘‘moneyness’’ of the
option. The term ‘‘moneyness’’ refers to the
relationship between the current market price of the
underlying interest and the exercise price.
16 The ‘‘delta’’ of an option represents the
sensitivity of the option price with respect to the
price of the underlying security.

GARCH model 17 to forecast the
volatility for each implied volatility risk
factor at the nine pivot points.18 For
each Shorter Tenor Option in the
account of a Clearing Member, changes
in its implied volatility are simulated
using forecasts obtained from daily
implied volatility market data according
to the corresponding pivot point and the
price of the option is computed to
determine the amount of profit or loss
in the account under the particular
STANS price simulation. Additionally,
OCC uses simulated closing prices for
the assets underlying the options in the
account of a Clearing Member that are
scheduled to expire within the
liquidation time horizon of two business
days to compute the options’ intrinsic
value and uses those values to help
calculate the profit or loss in the
account.19
OCC performed a number of analyses
of its current Implied Volatility Model
and to support development of the
proposed model changes, including
backtesting and impact analysis of the
proposed model enhancements as well
as comparison of OCC’s current model
performance against certain industry
benchmarks.20 OCC’s analysis
demonstrated that one attribute of the
current model is that the volatility
changes forecasted by the GARCH
model are extremely sensitive to sudden
spikes in volatility, which can at times
result in over reactive margin
requirements that OCC believes are
unreasonable and procyclical.21
For example, on February 5, 2018, the
market experienced extreme levels of
volatility, with the Cboe Volatility Index
(‘‘VIX’’) 22 moving from 17% up to 37%,
17 The acronym ‘‘GARCH’’ refers to an
econometric model that can be used to estimate
volatility based on historical data. See generally
Tim Bollerslev, ‘‘Generalized Autoregressive
Conditional Heteroskedasticity,’’ Journal of
Econometrics, 31(3), 307–327 (1986).
18 STANS relies on 10,000 price simulation
scenarios that are based generally on a historical
data period of 500 business days, which are
updated daily to keep model results from becoming
stale.
19 For such Shorter Tenor Options that are
scheduled to expire on the open of the market
rather than the close, OCC uses the relevant
opening price for the underlying assets.
20 OCC has provided results of these analyses to
the Commission in confidential Exhibit 3 of the
filing.
21 A quality that is positively correlated with the
overall state of the market is deemed to be
‘‘procyclical.’’ For example, procyclicality may be
evidenced by increasing margin requirements in
times of stressed market conditions and low margin
requirements when markets are calm. Hence, antiprocyclical features in a model are measures
intended to prevent risk-based models from
fluctuating too drastically in response to changing
market conditions.
22 The VIX is an index designed to measure the
30-day expected volatility of the Standard & Poor’s
500 index (‘‘SPX’’).

representing a relative move of 116%
(which is the largest relative daily jump
in the history of the index). Under
OCC’s current model, OCC observed
that the GARCH forecast SPX volatility
for at-the-money implied volatility for a
one-month tenor was approximately 4
times larger than the comparable market
index, the Cboe VVIX Index, which is a
volatility of volatility measure in that it
represents the expected volatility of the
30-day forward price of the VIX. As a
result, aggregated STANS margins
jumped more than 80% overnight due to
the GARCH model and margins for
certain individual Clearing Members
increased by a factor of 10.23
In addition, volatility tends to be
mean reverting; that is, volatility will
quickly return to its long-run mean or
average from an elevated level, so it is
unlikely that volatility would continue
to make big jumps immediately
following a drastic increase. For
example, based on the VIX history from
1990–2018, VIX levels jumped above 35
(about the level observed on February 5,
2018) for approximately 293 days (i.e.,
4% of the sample period). From the
level of 35 or higher, the range of daily
change on the VIX index was between
27% and -35%. However, the largest
daily changes on one-month at-themoney SPX implied volatility forecasted
by OCC’s current GARCH model on
February 5, 2018, were far in excess of
those historical realized amounts, which
points to extreme procyclicality issues
that need to be addressed in the current
model.24
OCC also performed backtesting of the
current model and proposed model
enhancements to evaluate and compare
the performance of each model from a
margin coverage perspective. OCC’s
backtesting demonstrated that
exceedance counts 25 and overall
coverage levels over the backtesting
period using the proposed model
enhancements were substantially
similar to the results obtained from the
current production model. As a result,
OCC believes the current model tends to
23 For example, under the current model the total
margin requirement calculated for one particular
Clearing Member jumped from $120 million on
February 2, 2018, to $1.78 billion on February 5,
2018, representing a 14 times increase in the
requirement.
24 For example, OCC’s current model resulted in
a maximum variation of 1100% in the one-month
at-the-money SPX implied volatility pivot when
compared with a maximum 35% move in the VIX
for VIX levels greater than 30. Additionally, the
model-generated number is significantly higher
than 116%, which is the largest realized historical
move in the VIX that occurred on February 5, 2018.
25 Exceedance counts here refer to instances
where the actual loss on portfolio over the
liquidation period of two business days exceeds the
margin amounts generated by the model.

be overly conservative/reactive, and the
proposed model is more appropriately
commensurate with the risks presented
by changes in implied volatility.
OCC believes that the sudden,
extreme and unreasonable increases in
margin requirements that may be
experienced under its current Implied
Volatility Model may stress certain
Clearing Members’ ability to obtain
sufficient liquidity to meet these
significantly increased margin
requirements, particularly in periods of
sudden, extreme volatility. OCC
therefore is proposing changes to its
Implied Volatility Model to limit
procyclicality and produce margin
requirements that OCC believes are
more reasonable and are also
commensurate with the risks presented
by its cleared options products.
Proposed Changes
OCC proposes to modify its Implied
Volatility Model by introducing an
exponentially weighted moving
average 26 for the daily forecasted
volatility for implied volatility risk
factors calculated using the GARCH
model. Specifically, when forecasting
the volatility for each implied volatility
risk factor at each of the nine pivot
points, OCC would use an exponentially
weighted moving average of forecasted
volatilities over a specified look-back
period rather than using raw daily
forecasted volatilities. The
exponentially weighted moving average
would involve the selection of a lookback period over which the data would
be averaged and a decay factor (or
weighting factor), which is a positive
number between zero and one, that
represents the weighting factor for the
most recent data point.27 The look-back
period and decay factor would be model
parameters subject to monthly review,28
along with other model parameters that
are reviewed by OCC’s Model Risk
Working Group (‘‘MRWG’’) 29 in
26 An exponentially weighted moving average is
a statistical method that averages data in a way that
gives more weight to the most recent observations
using an exponential scheme.
27 The lower the number the more weight is
attributed to the more recent data (e.g., if the value
is set to one, the exponentially weighted moving
average becomes a simple average).
28 OCC initially would use a look-back period of
22 days and an initial decay factor of 0.94 for the
exponentially weighted moving average. OCC
believes the 22-day look-back is an appropriate
initial parameter setting as it would allow for close
to monthly updates of the GARCH parameters used
in the model. The decay factor value of 0.94 was
selected based on the factor initially proposed by
JP Morgan’s RiskMetrics methodology (see
JPMorgan/Reuters, 1996. ‘‘RiskMetrics—Technical
Document’’, Fourth edition).
29 The MRWG is responsible for assisting OCC’s
Management Committee in overseeing and
governing OCC’s model-related risk issues and

accordance with OCC’s internal
procedure for margin model parameter
review and sensitivity analysis, and
these parameters would be subject to
change upon approval of the MRWG.
The proposed changes are intended to
reduce the oversensitivity of the current
Implied Volatility Model to large,
sudden shocks in market volatility and
therefore result in margin requirements
that are more stable and that remain
commensurate with the risks presented
during periods of sudden, extreme
volatility.30 The proposed changes are
expected to produce margin
requirements that are very similar to
those generated using OCC’s existing
model during quiet, less volatile market
periods; however, during more volatile
periods, the proposed changes would
result in a more measured initial
response to increases in the volatility of
volatility with margin requirements that
may remain elevated for a longer period
of time after the shock subsides than
experienced under OCC’s current
model. The proposed changes are
intended to reduce procyclicality in
OCC’s margin methodology across
volatile market periods while
continuing to capture changes in
implied volatility and produce margin
requirements that are commensurate
with the risks presented by OCC’s
cleared options products. The proposed
changes therefore would reduce the risk
that a sudden, extreme increase in
margin requirements may stress
Clearing Members’ ability to obtain
liquidity to meet such increased
requirements, particularly in periods of
extreme volatility.
spikes in volatility, which can at times
result in over reactive margin
requirements that OCC believes are
unreasonable and procyclical (for the
reasons set forth above). Such sudden,
unreasonable increases in margin
requirements may stress certain Clearing
Members’ ability to obtain liquidity to
meet those requirements, particularly in
periods of extreme volatility, and could
result in a Clearing Member being
delayed in meeting, or ultimately failing
to meet, its daily settlement obligations
to OCC. OCC notes that the proposed
changes are expected to produce margin
requirements that are very similar to
those generated using OCC’s existing
model during quiet, less volatile market
periods. The proposed changes would,
however, result in a more measured
initial response to increases in the
volatility of volatility with margin
requirements that may remain elevated
for a longer period after the shock
subsides than experienced under OCC’s
current model. The proposed changes
would therefore reduce the likelihood
that OCC’s Implied Volatility Model
would produce extreme, over reactive
margin requirements that could strain
the ability of certain Clearing Members
to meet their daily margin requirements
at OCC by reducing procyclicality in
OCC’s margin methodology and
ensuring more stable and appropriate
changes in margin requirements across
volatile market periods while
continuing to capture changes in
implied volatility and produce margin
requirements that are commensurate
with the risks presented.
Implementation Timeframe
OCC expects to implement the
proposed changes within thirty (30)
days after the date that OCC receives all
necessary regulatory approvals for the
proposed changes. OCC will announce
the implementation date of the
proposed change by an Information
Memorandum posted to its public
website at least 2 weeks prior to
implementation.

November 20, 2018.
Pursuant to Section 19(b)(1) of the
Securities Exchange Act of 1934
(‘‘Act’’) 1 and Rule 19b–4 thereunder,2
notice is hereby given that on November
14, 2018, The Nasdaq Stock Market LLC
(‘‘Nasdaq’’ or the ‘‘Exchange’’) filed with
the Securities and Exchange
Commission (‘‘SEC’’ or ‘‘Commission’’)
the proposed rule change as described
in Items I and II below, which Items
have been prepared by the Exchange.
The Commission is publishing this
notice to solicit comments on the
proposed rule change from interested
persons.
I. Self-Regulatory Organization’s
Statement of the Terms of Substance of
the Proposed Rule Change
The Exchange proposes to amend
Nasdaq Rule 5615(b)(4) to change the
threshold for listed companies that are
eligible to benefit from the exemptions
from the Exchange’s compensation
committee requirements applicable to
smaller reporting companies so that all
companies that qualify for smaller
reporting company status under the
revised SEC definition will qualify for
the Exchange’s exemptions.

the most significant aspects of such
statements.
A. Self-Regulatory Organization’s
Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule
Change
1. Purpose
The purpose of the proposed rule
change is to amend Rule 5615(b)(4) to
change the threshold for listed
companies that are eligible to benefit
from the exemptions from the
Exchange’s compensation committee
requirements applicable to smaller
reporting companies so that all
companies that qualify for smaller
reporting company status under the
revised SEC definition will qualify for
the Exchange’s exemptions.
The SEC recently adopted 3
amendments to the definition of
‘‘smaller reporting company’’ set forth
in Item 10(f)(1) of Regulation S–K,4 Rule
12b–2 under the Act 5 and Rule 405
under the Securities Act of 1933.6 The
amendments raise the smaller reporting
company cap from less than $75 million
in public float to less than $250 million
and also include as smaller reporting
companies issuers with less than $100
million in annual revenues if they also
have either no public float or a public
float that is less than $700 million. The
amendments became effective on
September 10, 2018. As a result of the
SEC rule changes, an expanded number
of registrants, and hence, of listed
companies, will qualify for smaller
reporting company status than was
previously the case.7
Smaller reporting companies are
entitled to avail themselves of certain
exemptions from Nasdaq’s
compensation committee requirements.8
3 See Release Nos. 33–10513 and 34–83550 (June
28, 2018); 83 FR 31992 (July 10, 2018) (the
‘‘Adopting Release’’).

5 17 CFR 240.12b–2.
6 17 CFR 230.405.
7 See the Adopting Release.
8 Specifically, pursuant to Rule 5605(d)(5), a
listed company that satisfies the definition of
smaller reporting company is not required to
comply with: (i) The additional requirements with
respect to the independence of compensation
committee members set forth in Rule 5605(d)(2)(A);
(ii) the requirements with respect to the specific
compensation committee responsibilities and
authority set forth in Rule 5605(d)(3) and the
requirement to include such responsibilities and
authority in its compensation committee charter as
set forth in Rule 5605(d)(1)(D); or (iii) the
requirement with respect to the compensation
committee’s responsibility to review and reassess
the adequacy of its compensation committee charter
on an annual basis. A listed smaller reporting
company must comply with all other applicable
Exchange corporate governance requirements,

Description of the Proposed Change
Background
STANS Overview
STANS is OCC's proprietary risk management system for calculating
Clearing Member margin requirements.\7\ The STANS methodology utilizes
large-scale Monte Carlo simulations to forecast price and volatility
movements in determining a Clearing Member's margin requirement.\8\
STANS margin requirements are calculated at the portfolio level of
Clearing Member accounts with positions in marginable securities and
consists of an estimate of two primary components: A base component and
a stress test add-on component. The base component is an estimate of a
99% expected shortfall \9\ over a two-day time horizon. The
concentration/dependence stress test charge is obtained by considering
increases in the expected margin shortfall for an account that would
occur due to (i) market movements that are especially large and/or in
which certain risk factors would exhibit perfect or zero correlations
rather than correlations otherwise estimated using historical data or
(ii) extreme and adverse idiosyncratic movements for individual risk
factors to which the account is particularly exposed. The STANS
methodology is used to measure the exposure of portfolios of options
and futures cleared by OCC and cash instruments in margin
collateral.\10\
---------------------------------------------------------------------------
\7\ See Securities Exchange Act Release No. 53322 (February 15,
2006), 71 FR 9403 (February 23, 2006) (SR-OCC-2004-20). A detailed
description of the STANS methodology is available at https://optionsclearing.com/risk-management/margins/.
\8\ See OCC Rule 601.
\9\ The expected shortfall component is established as the
estimated average of potential losses higher than the 99% value at
risk threshold. The term ``value at risk'' or ``VaR'' refers to a
statistical technique that, generally speaking, is used in risk
management to measure the potential risk of loss for a given set of
assets over a particular time horizon.
\10\ OCC notes that, pursuant to OCC Rule 601(e)(1), OCC also
calculates initial margin requirements for segregated futures
accounts using the Standard Portfolio Analysis of Risk Margin
Calculation System (``SPAN''). No changes are proposed to OCC's use
of SPAN because the proposed changes do not concern futures. See
Securities Exchange Act Release No. 72331 (June 5, 2014), 79 FR
33607 (June 11, 2014) (SR-OCC-2014-13).
---------------------------------------------------------------------------
The econometric models underlying STANS currently incorporate a
number of risk factors. A ``risk factor'' within OCC's margin system is
defined as a product or attribute whose historical data is used to
estimate and simulate the risk for an associated product. The majority
of risk factors utilized in the STANS methodology are the returns on
individual equity securities; however, a number of other risk factors
may be considered, including, among other things, returns on implied
volatility risk factors.\11\
---------------------------------------------------------------------------
\11\ In December 2015, the Commission approved a proposed rule
change and issued a Notice of No Objection to an advance notice
filing by OCC to its modify margin methodology by more broadly
incorporating variations in implied volatility within STANS. See
Securities Exchange Act Release No. 76781 (December 28, 2015), 81 FR
135 (January 4, 2016) (SR-OCC-2015-016) and Securities Exchange Act
Release No. 76548 (December 3, 2015), 80 FR 76602 (December 9, 2015)
(SR-OCC-2015-804). As discussed further below, implied volatility
risk factors in STANS are a set of chosen volatility pivot points
per product, depending on the tenor of the option.
---------------------------------------------------------------------------
Current Implied Volatility Model in STANS
Generally speaking, the implied volatility of an option is a
measure of the expected future volatility of the option's underlying
security at expiration, which is reflected in the current option
premium in the market. Using the Black-Scholes options pricing model,
the implied volatility is the standard deviation of the underlying
asset price necessary to arrive at the market price of an option of a
given strike, time to maturity, underlying asset price and the current
risk-free rate. In effect, the implied volatility is
[[Page 60542]]
responsible for that portion of the premium that cannot be explained by
the then-current intrinsic value of the option (i.e., the difference
between the price of the underlying and the exercise price of the
option), discounted to reflect its time value. OCC considers variations
in implied volatility within STANS to ensure that the anticipated cost
of liquidating options positions in an account recognizes the
possibility that implied volatility could change during the two-
business day liquidation time horizon and lead to corresponding changes
in the market prices of the options.
OCC models the variations in implied volatility used to re-price
options within STANS for substantially all option contracts \12\
available to be cleared by OCC that have a residual tenor \13\ of less
than three years (``Shorter Tenor Options'').\14\ To address variations
in implied volatility, OCC models a volatility surface \15\ for Shorter
Tenor Options by incorporating into the econometric models underlying
STANS certain risk factors (i.e., implied volatility pivot points)
based on a range of tenors and option deltas.\16\ Currently, these
implied volatility pivot points consist of three tenors of one month,
three months and one year, and three deltas of 0.25, 0.5, and 0.75,
resulting in nine implied volatility risk factors. These pivot points
are chosen such that their combination allows the model to capture
changes in level, skew, convexity and term structure of the implied
volatility surface. OCC uses a GARCH model \17\ to forecast the
volatility for each implied volatility risk factor at the nine pivot
points.\18\ For each Shorter Tenor Option in the account of a Clearing
Member, changes in its implied volatility are simulated using forecasts
obtained from daily implied volatility market data according to the
corresponding pivot point and the price of the option is computed to
determine the amount of profit or loss in the account under the
particular STANS price simulation. Additionally, OCC uses simulated
closing prices for the assets underlying the options in the account of
a Clearing Member that are scheduled to expire within the liquidation
time horizon of two business days to compute the options' intrinsic
value and uses those values to help calculate the profit or loss in the
account.\19\
---------------------------------------------------------------------------
\12\ OCC's Implied Volatility Model excludes: (i) Binary
options, (ii) options on commodity futures, (iii) options on U.S.
Treasury securities, and (iv) Asians and Cliquets. These relatively
new products were introduced as the implied volatility margin
methodology changes were in the process of being completed by OCC,
and OCC had de minimus open interest in those options. OCC therefore
did not believe there was a substantive risk if those products were
excluded from the implied volatility model. See id.
\13\ The ``tenor'' of an option is the amount of time remaining
to its expiration.
\14\ OCC also incorporates variations in implied volatility as
risk factors for certain options with residual tenors of at least
three years (``Longer Tenor Options''); however, the proposed
changes described herein would not apply to OCC's model for Longer
Tenor Options. See Securities Exchange Act Release Nos. 68434
(December 14, 2012), 77 FR 57602 (December 19, 2012) (SR-OCC-2012-
14); 70709 (October 18, 2013), 78 FR 63267 (October 23, 2013) (SR-
OCC-2013-16).
\15\ The term ``volatility surface'' refers to a three-
dimensional graphed surface that represents the implied volatility
for possible tenors of the option and the implied volatility of the
option over those tenors for the possible levels of ``moneyness'' of
the option. The term ``moneyness'' refers to the relationship
between the current market price of the underlying interest and the
exercise price.
\16\ The ``delta'' of an option represents the sensitivity of
the option price with respect to the price of the underlying
security.
\17\ The acronym ``GARCH'' refers to an econometric model that
can be used to estimate volatility based on historical data. See
generally Tim Bollerslev, ``Generalized Autoregressive Conditional
Heteroskedasticity,'' Journal of Econometrics, 31(3), 307-327
(1986).
\18\ STANS relies on 10,000 price simulation scenarios that are
based generally on a historical data period of 500 business days,
which are updated daily to keep model results from becoming stale.
\19\ For such Shorter Tenor Options that are scheduled to expire
on the open of the market rather than the close, OCC uses the
relevant opening price for the underlying assets.
---------------------------------------------------------------------------
OCC performed a number of analyses of its current Implied
Volatility Model and to support development of the proposed model
changes, including backtesting and impact analysis of the proposed
model enhancements as well as comparison of OCC's current model
performance against certain industry benchmarks.\20\ OCC's analysis
demonstrated that one attribute of the current model is that the
volatility changes forecasted by the GARCH model are extremely
sensitive to sudden spikes in volatility, which can at times result in
over reactive margin requirements that OCC believes are unreasonable
and procyclical.\21\
---------------------------------------------------------------------------
\20\ OCC has provided results of these analyses to the
Commission in confidential Exhibit 3 of the filing.
\21\ A quality that is positively correlated with the overall
state of the market is deemed to be ``procyclical.'' For example,
procyclicality may be evidenced by increasing margin requirements in
times of stressed market conditions and low margin requirements when
markets are calm. Hence, anti-procyclical features in a model are
measures intended to prevent risk-based models from fluctuating too
drastically in response to changing market conditions.
---------------------------------------------------------------------------
For example, on February 5, 2018, the market experienced extreme
levels of volatility, with the Cboe Volatility Index (``VIX'') \22\
moving from 17% up to 37%, representing a relative move of 116% (which
is the largest relative daily jump in the history of the index). Under
OCC's current model, OCC observed that the GARCH forecast SPX
volatility for at-the-money implied volatility for a one-month tenor
was approximately 4 times larger than the comparable market index, the
Cboe VVIX Index, which is a volatility of volatility measure in that it
represents the expected volatility of the 30-day forward price of the
VIX. As a result, aggregated STANS margins jumped more than 80%
overnight due to the GARCH model and margins for certain individual
Clearing Members increased by a factor of 10.\23\
---------------------------------------------------------------------------
\22\ The VIX is an index designed to measure the 30-day expected
volatility of the Standard & Poor's 500 index (``SPX'').
\23\ For example, under the current model the total margin
requirement calculated for one particular Clearing Member jumped
from $120 million on February 2, 2018, to $1.78 billion on February
5, 2018, representing a 14 times increase in the requirement.
---------------------------------------------------------------------------
In addition, volatility tends to be mean reverting; that is,
volatility will quickly return to its long-run mean or average from an
elevated level, so it is unlikely that volatility would continue to
make big jumps immediately following a drastic increase. For example,
based on the VIX history from 1990-2018, VIX levels jumped above 35
(about the level observed on February 5, 2018) for approximately 293
days (i.e., 4% of the sample period). From the level of 35 or higher,
the range of daily change on the VIX index was between 27% and -35%.
However, the largest daily changes on one-month at-the-money SPX
implied volatility forecasted by OCC's current GARCH model on February
5, 2018, were far in excess of those historical realized amounts, which
points to extreme procyclicality issues that need to be addressed in
the current model.\24\
---------------------------------------------------------------------------
\24\ For example, OCC's current model resulted in a maximum
variation of 1100% in the one-month at-the-money SPX implied
volatility pivot when compared with a maximum 35% move in the VIX
for VIX levels greater than 30. Additionally, the model-generated
number is significantly higher than 116%, which is the largest
realized historical move in the VIX that occurred on February 5,
2018.
---------------------------------------------------------------------------
OCC also performed backtesting of the current model and proposed
model enhancements to evaluate and compare the performance of each
model from a margin coverage perspective. OCC's backtesting
demonstrated that exceedance counts \25\ and overall coverage levels
over the backtesting period using the proposed model enhancements were
substantially similar to the results obtained from the current
production model. As a result, OCC believes the current model tends to
[[Page 60543]]
be overly conservative/reactive, and the proposed model is more
appropriately commensurate with the risks presented by changes in
implied volatility.
---------------------------------------------------------------------------
\25\ Exceedance counts here refer to instances where the actual
loss on portfolio over the liquidation period of two business days
exceeds the margin amounts generated by the model.
---------------------------------------------------------------------------
OCC believes that the sudden, extreme and unreasonable increases in
margin requirements that may be experienced under its current Implied
Volatility Model may stress certain Clearing Members' ability to obtain
sufficient liquidity to meet these significantly increased margin
requirements, particularly in periods of sudden, extreme volatility.
OCC therefore is proposing changes to its Implied Volatility Model to
limit procyclicality and produce margin requirements that OCC believes
are more reasonable and are also commensurate with the risks presented
by its cleared options products.
Proposed Changes
OCC proposes to modify its Implied Volatility Model by introducing
an exponentially weighted moving average \26\ for the daily forecasted
volatility for implied volatility risk factors calculated using the
GARCH model. Specifically, when forecasting the volatility for each
implied volatility risk factor at each of the nine pivot points, OCC
would use an exponentially weighted moving average of forecasted
volatilities over a specified look-back period rather than using raw
daily forecasted volatilities. The exponentially weighted moving
average would involve the selection of a look-back period over which
the data would be averaged and a decay factor (or weighting factor),
which is a positive number between zero and one, that represents the
weighting factor for the most recent data point.\27\ The look-back
period and decay factor would be model parameters subject to monthly
review,\28\ along with other model parameters that are reviewed by
OCC's Model Risk Working Group (``MRWG'') \29\ in accordance with OCC's
internal procedure for margin model parameter review and sensitivity
analysis, and these parameters would be subject to change upon approval
of the MRWG.
---------------------------------------------------------------------------
\26\ An exponentially weighted moving average is a statistical
method that averages data in a way that gives more weight to the
most recent observations using an exponential scheme.
\27\ The lower the number the more weight is attributed to the
more recent data (e.g., if the value is set to one, the
exponentially weighted moving average becomes a simple average).
\28\ OCC initially would use a look-back period of 22 days and
an initial decay factor of 0.94 for the exponentially weighted
moving average. OCC believes the 22-day look-back is an appropriate
initial parameter setting as it would allow for close to monthly
updates of the GARCH parameters used in the model. The decay factor
value of 0.94 was selected based on the factor initially proposed by
JP Morgan's RiskMetrics methodology (see JPMorgan/Reuters, 1996.
``RiskMetrics--Technical Document'', Fourth edition).
\29\ The MRWG is responsible for assisting OCC's Management
Committee in overseeing and governing OCC's model-related risk
issues and includes representatives from OCC's Financial Risk
Management department, Quantitative Risk Management department,
Model Validation Group, and Enterprise Risk Management department.
---------------------------------------------------------------------------
The proposed changes are intended to reduce the oversensitivity of
the current Implied Volatility Model to large, sudden shocks in market
volatility and therefore result in margin requirements that are more
stable and that remain commensurate with the risks presented during
periods of sudden, extreme volatility.\30\ The proposed changes are
expected to produce margin requirements that are very similar to those
generated using OCC's existing model during quiet, less volatile market
periods; however, during more volatile periods, the proposed changes
would result in a more measured initial response to increases in the
volatility of volatility with margin requirements that may remain
elevated for a longer period of time after the shock subsides than
experienced under OCC's current model. The proposed changes are
intended to reduce procyclicality in OCC's margin methodology across
volatile market periods while continuing to capture changes in implied
volatility and produce margin requirements that are commensurate with
the risks presented by OCC's cleared options products. The proposed
changes therefore would reduce the risk that a sudden, extreme increase
in margin requirements may stress Clearing Members' ability to obtain
liquidity to meet such increased requirements, particularly in periods
of extreme volatility.

\30\ As noted above, OCC has performed analysis of the impact of
the proposed changes, and OCC's backtesting of the proposed model
demonstrates comparable exceedance counts and coverage levels to the
current model during the most recent volatile period.
---------------------------------------------------------------------------
Implementation Timeframe
OCC expects to implement the proposed changes within thirty (30)
days after the date that OCC receives all necessary regulatory
approvals for the proposed changes. OCC will announce the
implementation date of the proposed change by an Information Memorandum
posted to its public website at least 2 weeks prior to implementation.
Anticipated Effect on, and Management of, Risk
The volatility changes forecasted by OCC's current Implied
Volatility Model are extremely sensitive to large, sudden spikes in
volatility, which can at times result in over reactive margin
requirements that OCC believes are unreasonable and procyclical (for
the reasons set forth above). Such sudden, unreasonable increases in
margin requirements may stress certain Clearing Members' ability to
obtain liquidity to meet those requirements, particularly in periods of
extreme volatility, and could result in a Clearing Member being delayed
in meeting, or ultimately failing to meet, its daily settlement
obligations to OCC. OCC notes that the proposed changes are expected to
produce margin requirements that are very similar to those generated
using OCC's existing model during quiet, less volatile market periods.
The proposed changes would, however, result in a more measured initial
response to increases in the volatility of volatility with margin
requirements that may remain elevated for a longer period after the
shock subsides than experienced under OCC's current model. The proposed
changes would therefore reduce the likelihood that OCC's Implied
Volatility Model would produce extreme, over reactive margin
requirements that could strain the ability of certain Clearing Members
to meet their daily margin requirements at OCC by reducing
procyclicality in OCC's margin methodology and ensuring more stable and
appropriate changes in margin requirements across volatile market
periods while continuing to capture changes in implied volatility and
produce margin requirements that are commensurate with the risks
presented.
Consistency With the Payment, Clearing and Settlement Supervision Act
The stated purpose of the Clearing Supervision Act is 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.\31\
Section 805(a)(2) of the Clearing Supervision Act \32\ also authorizes
the Commission to prescribe risk management standards for the payment,
clearing and settlement activities of designated clearing entities,
like OCC, for which the Commission is the supervisory agency. Section
805(b) of the Clearing Supervision Act \33\ states that the objectives
and principles for
[[Page 60544]]
risk management standards prescribed under Section 805(a) shall be to:
---------------------------------------------------------------------------
\31\ 12 U.S.C. 5461(b).

\33\ 12 U.S.C. 5464(b).
---------------------------------------------------------------------------
Promote robust risk management;
promote safety and soundness;
reduce systemic risks; and
support the stability of the broader financial system.
OCC believes that the proposed changes described herein would
enhance its margin methodology in a manner consistent with the
objectives and principles of Section 805(b) of the Clearing Supervision
Act \34\ and the risk management standards adopted by the Commission in
Rule 17Ad-22 under the Act for the reasons set forth below.\35\

Nos. 68080 (October 22, 2012), 77 FR 66220 (November 2, 2012) (S7-
08-11) (``Clearing Agency Standards''); 78961 (September 28, 2016),
81 FR 70786 (October 13, 2016) (S7-03-14) (``Standards for Covered
Clearing Agencies''). The Standards for Covered Clearing Agencies
became effective on December 12, 2016. OCC is a ``covered clearing
agency'' as defined in Rule 17Ad-22(a)(5) and therefore must comply
with the requirements of Rule 17Ad-22(e).
---------------------------------------------------------------------------
OCC believes the proposed changes are consistent with the
objectives and principles of Section 805(b) of the Clearing Supervision
Act \36\ in that they would promote robust risk management and safety
and soundness while reducing systemic risks and supporting the
stability of the broader financial system. As discussed above, the
volatility changes forecasted by OCC's current Implied Volatility Model
are extremely sensitive to large, sudden spikes in volatility, which
can at times result in over reactive margin requirements that OCC
believes are unreasonable and procyclical. Such sudden, unreasonable
increases in margin requirements may stress certain Clearing Members'
ability to obtain liquidity to meet those requirements, particularly in
periods of extreme volatility, and could result in a Clearing Member
being delayed in meeting, or ultimately failing to meet, its daily
settlement obligations to OCC. OCC notes that the proposed changes are
expected to produce margin requirements that are very similar to those
generated using OCC's existing model during quiet, less volatile market
periods. The proposed changes would, however, result in a more measured
initial response to increases in the volatility of volatility with
margin requirements that may remain elevated for a longer period after
the shock subsides than experienced under OCC's current model. The
proposed changes would therefore reduce the likelihood that OCC's
Implied Volatility Model would produce extreme, over reactive margin
requirements by reducing procyclicality in OCC's margin methodology and
ensuring more stable and appropriate changes in margin requirements
across volatile market periods while continuing to provide for robust
management of the risks presented by the implied volatility of OCC's
cleared options products. Accordingly, OCC believes the proposed
changes would promote robust risk management and safety and soundness
while reducing systemic risks and supporting the stability of the
broader financial system.

Rules 17Ad-22(e)(6)(i) and (v) \37\ require a covered clearing
agency that provides central counterparty services 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 (1) considers, and
produces margin levels commensurate with, the risks and particular
attributes of each relevant product, portfolio, and market and (2) uses
an appropriate method for measuring credit exposure that accounts for
relevant product risk factors and portfolio effects across products. As
noted above, OCC's current model for implied volatility demonstrates
extreme sensitivity to sudden spikes in volatility, which can at times
result in over reactive margin requirements that OCC believes are
unreasonable and procyclical. The proposed changes are designed to
reduce the oversensitivity of the model and produce margin requirements
that are commensurate with the risks presented during periods of
sudden, extreme volatility. The proposed model enhancements are
expected to produce margin requirements that are very similar to those
generated using OCC's existing model during quiet, less volatile market
periods; however, the proposed changes would result in a more measured
initial response to increases in the volatility of volatility with
margin requirements that may remain elevated for a longer period of
time after the shock subsides than experienced under OCC's current
model. The proposed changes are designed to reduce procyclicality in
OCC's margin methodology and ensure more stable changes in margin
requirements across volatile market periods while continuing to capture
changes in implied volatility and produce margin requirements that are
commensurate with the risks presented by OCC's cleared options. As a
result, OCC believes that the proposed changes are reasonably designed
to consider, and produce margin levels commensurate with, the risk
presented by the implied volatility of OCC's cleared options and use an
appropriate method for measuring credit exposure that accounts for this
product risk factor (i.e., implied volatility) in a manner consistent
with Rules 17Ad-22(e)(6)(i) and (v).\38\
