Description of the Proposed Change
OCC's margin methodology, the System for Theoretical Analysis and Numerical Simulations (“STANS”), is OCC's proprietary risk management system that calculates Clearing Member margin requirements.
STANS utilizes large-scale Monte Carlo simulations to forecast price and volatility movements in determining a Clearing Member's margin requirement.
The STANS margin requirement is calculated at the portfolio level of Clearing Member legal entity marginable net positions tier account (tiers can be customer, firm, or market marker) and consists of an estimate of a 99% 2-day expected shortfall (“99% Expected Shortfall”) and an add-on for model risk (the concentration/dependence stress test charge). The STANS methodology is used to measure the exposure of portfolios of options and futures cleared by OCC and cash instruments in margin collateral.
STANS margin requirements are comprised of the sum of several components, each reflecting a different aspect of risk. The base component of the STANS margin requirement for each account is obtained using a risk measure known as 99% Expected Shortfall. Under the 99% Expected Shortfall calculation, an account has a base margin excess (deficit) if its positions in cleared products, plus all existing collateral—whether of types included in the Monte Carlo simulation or of types subjected to traditional “haircuts”—would have a positive (negative) net worth after incurring a loss equal to the average of all losses beyond the 99% value at risk (or “VaR”) point. This base component is then adjusted by the addition of a stress test component, which is obtained from consideration of the increases in 99% Expected Shortfall that would arise from market movements that are especially large and/or in which various kinds of risk factors exhibit perfect or zero correlations in place of their correlations estimated from historical data, or from extreme adverse idiosyncratic movements in individual risk factors to which the account is particularly exposed.
STANS margin requirements are intended to cover potential losses due to price movements over a two-day risk horizon; however, the base and stress margin components do not cover the potential liquidation costs OCC may incur in closing out a defaulted Clearing Member's portfolio.
Closing out positions in a defaulted Clearing Member's portfolio could entail selling longs at bid price and covering shorts at ask price. This means that additional liquidation costs may need to take into account the bid-ask price spreads.
OCC is proposing to enhance its margin methodology by introducing a new model to estimate the liquidation cost for all options and futures, as well as the securities in margin collateral. As noted above, closing out positions of a defaulted Clearing Member in the open market could entail selling longs at bid price and covering shorts at ask price. These closing-out costs are currently not taken into account in STANS for all options (with the exception of long-dated SPX index option series, as noted above).
Therefore, the purpose of the proposed change is to add additional financial resources in the form of margin, based on liquidation cost grids calibrated using historical stressed periods, to guard against potential shortfalls in margin requirements that may arise due to the costs of liquidating Clearing Member portfolios in the event of a default. The liquidation cost charge would be applied as an add-on to all accounts incurring a STANS margin charge.
The proposed liquidation cost model calculates liquidation cost based on risk measures, gross contract volumes and market bid-ask spreads. In general, the proposed model would be used to calculate two risk-based liquidation costs for a portfolio, Vega 
liquidation cost (“Vega LC”) and Delta liquidation cost (“Delta LC”), using “Liquidation Grids.” 
Options products will incur both Vega and Delta LCs while Delta-one 
products such as futures contracts, Treasury securities and equity securities, will have only a Delta charge.
The proposed liquidation cost model described herein would include: (1) The decomposition of the defaulter's portfolio into sub-portfolios by underlying security; (2) the creation and calibration of Liquidation Grids used to determine liquidation costs; (3) the calculation of the Vega LC (including a minimum Vega LC charge) for options products; (4) the calculation of Delta LCs for both options and Delta-one products; (5) the calculation of Vega and Delta concentration factors; (6) the calculation of volatility correlations for Vega LCs; (7) the establishment of a STANS margin floor based on the liquidation cost; and (8) conforming changes to OCC's Margin Policy and Stress Testing and Clearing Fund Methodology Description.
The new liquidation cost model would cover the following cleared products in a Clearing Member's portfolio: Options on indices, equities, Exchange Traded Funds (“ETFs”) and futures; FLEX options; future contracts; Treasury securities; and stock loan and collateral securities. The securities not included in STANS margin calculations would not be covered by the new model.
The proposed approach to calculating liquidation costs and the conforming changes to OCC's Margin Policy are described in further detail below.Start Printed Page 23092
1. Portfolio Decomposition and Creation of Sub-Portfolios
For a portfolio consisting of many contracts and underlyings, the proposed model would first divide (or decompose) the portfolio into sub-portfolios by underlying security such that all contracts with the same underlying are grouped into the same sub-portfolio. The Vega LC and Delta LC are first calculated at a sub-portfolio level and then aggregated to derive the final liquidation cost for the total portfolio. All the option positions with the same fundamental underlying would form one sub-portfolio because they share the same risk characteristics. The equity index, index future and index ETFs would all be categorized by the underlying index that is the basis for the index, future, and ETF-underlying securities. The corresponding options on the index, index future, and ETFs would therefore fall into the same sub-portfolio. In addition, FLEX options on the same underlying would be included in the same sub-portfolio of the regular options. Similarly, cash products such as equities and futures would be grouped in the same sub-category based on their underlying symbols. All Treasury security positions would form one sub-portfolio. The calculation of Vega LC and Delta LC for each sub-portfolio is summarized in the next sections.
2. Creation and Calibration of Liquidation Grids
A key element of the proposed liquidation cost model is the “Liquidation Grids.” The calculations of Vega LC and Delta LC involve a number of liquidity-related quantities such as volatility bid-ask spreads, price bid-ask spreads, Vega notional, and Delta notional. The collection of these quantities would be used to create the following Liquidation Grids.
1. Vega Liquidation Grids (or volatility grids): The Vega Liquidation Grids would represent the level of bid-ask spreads on the implied volatility of option contracts for a given underlying. Since the volatility spreads of option contracts vary by the Delta and tenor of the option, OCC would divide the contracts into several Delta buckets by tenor buckets.
Each pair (Delta, tenor) is referred to as a Vega bucket. For each bucket, an average volatility spread is estimated and defined as the volatility grid for the bucket. The size of grid would essentially represent the cost for liquidating one unit of Vega risk in the bucket.
2. Vega Notional Grid: The Vega Notional Grid of an underlying security would be the average trading options volume weighted by the Vega of all options on the given underlying. The size of Vega Notional grids would indicate the average daily trading volume in terms of dollar Vegas (i.e., the Vega multiplied by the volume of the option).
3. Delta Liquidation Grid: The Delta liquidation grid would represent an estimated bid-ask price spread (in percentage) on the underlying.
It represents the cost of liquidating one dollar unit of the underlying security. The Delta liquidation grid for Treasury securities represents bid-ask yield spreads, expressed in basis points.
4. Delta Notional Grid: The Delta Notional grid of an underlying security would represent the average trading volume in dollars of the security.
Vega Notional Grids are calibrated at the security level; that is, each individual underlying security would have its own Vega Notional. The Delta Notional Grid and both Vega and Delta Liquidation Grids for all underlying securities are estimated at the levels of a fixed number of classes based on their liquidity level.
All equity securities would be divided, based on their membership in commonly used market indices (including, but not limited to, the S&P 100 and 500 index) or other market liquidity measurements, into liquidity classes (which may include, but are not limited to, High Liquid Equities, Medium Liquid Equities and Low Liquid Equities). Any new equity security would generally default to the lowest liquidity classification unless otherwise assigned to a higher liquidity classification when deemed necessary. Major indices (e.g., SPX or the Cboe Volatility Index (“VIX”)) may form their own index liquidity class, which may cover indices, index ETFs, and index futures. In addition, sector ETFs, ETFs on a major commodity (such as Gold, Crude/Natural Gas, Metals, and Electricity), and Treasury ETFs would generally each form individual classes of their own, subject to the availability of liquidation data. Pursuant to the proposed Margins Methodology, these liquidity classes would be reviewed annually or at a frequency determined by OCC's MRWG and updated as needed, taking into consideration such factors including, but not limited to, changes in membership of the S&P 100 index and S&P 500 index, listing and delisting of securities, and any corporate actions on the existing securities.
Because the bid-ask spreads can change daily, the use of spreads from current market conditions could cause liquidation costs to fluctuate dramatically with market volatility, especially during a stressed market period. To mitigate this procyclicality issue, Liquidation Grids would be calibrated from several historical stressed periods, which are selected based on the history of VIX index levels and would remain unchanged with time until a new stressed period is selected and added to the calibrations in accordance with the requirements of the proposed Margins Methodology.
3. Vega Liquidation Cost
Vega Liquidation Cost Calculation
Vega LC is the main component of the proposed liquidation cost model. For a simple option contract, the Vega LC would be its position Vega multiplied by its respective bucket in the Vega Liquidation Grid. The result is approximately equal to one half of the bid-ask price spread. For a portfolio consisting of many contracts and underlyings, the model first divides the portfolio into sub-portfolios by underlying security such that all contracts with the same underlying are grouped into the same sub-portfolio (as described above). The Vega LCs for sub-portfolios are calculated first and then aggregated to derive the Vega LC for the total portfolio.Start Printed Page 23093
The Vega LC for a sub-portfolio, which consists of all the contracts with the same underlying security, would be calculated in several steps. First, the Liquidation Grids would be calibrated for Vega “buckets” that consist of Delta bins by tenor bins as discussed above. These Vega buckets are used to represent the volatility risk at the different areas on the implied volatility surface. Next, the Vega of each contract position in a given sub-portfolio would be calculated and bucketed into one of the Vega buckets. The Vegas falling into the same Vega bucket would then be netted. The Vega LC for each of the Vega buckets is calculated as the net Vega multiplied by the Vega grid of the buckets. Finally, the total liquidation cost for the sub-portfolio would be aggregated from these bucket Vega LCs by using correlations between the Vega buckets. Since the sub-portfolios are formed by the fundamental equity or index underlying the option, the Vega LCs of closely related but different underlying securities are allowed to net. For example, Vega LCs for SPX and related indices, futures, and ETFs that are based on the S&P 500 index would be allowed 100% netting.
The Vega LC for the total portfolio would be a similar correlation-based sum of Vega LCs of all the sub-portfolios, taking into account correlations between the products' implied volatility.
Minimum Liquidation Cost
Because the proposed model allows risk netting across closely related option contracts, it is possible that a well-hedged option strategy could result in a very small or zero liquidation cost. To prevent this from happening, a minimum liquidation cost would be introduced to the Vega liquidation charges. The minimum liquidation cost for a sub-portfolio would be calculated as the gross number of option contracts multiplied by a minimum cost per contract value.
The minimum cost amount would be calculated for the entire portfolio and would be used to floor the final total Vega LC. The proposal would not apply a minimum cost for Delta LC due to the immaterial impact a minimum Delta LC would have on the overall liquidation cost charge.
4. Delta Liquidation Cost
In addition to Vega risk, the model also considers the Delta risk presented in an entire portfolio. If a portfolio has positions in either options, futures, equities, or Treasury securities, it will contain some Delta risk. Under the proposed model, the liquidation cost due to Delta risk in a sub-portfolio (as defined by the underlying) would be approximated by the net dollar Delta of the sub-portfolio multiplied by its respective bucket in the Delta Liquidation Grid.
The proposed model would allow netting of Delta LC if the option contracts, futures, or equity positions belong to or are related to a top index (such as SPX or VIX). For example, in a portfolio, positions in SPX-related options, options on futures, futures, or collateral have their Delta LC netted.
Under the proposed model, U.S. dollar Treasury bonds would form one sub-portfolio. The Delta or DV01 (i.e., dollar value of one basis point) of all the bonds would be calculated and bucketed into six tenor buckets. For each bucket, the liquidation cost would be approximated by the absolute value of the net DV01 of the bucket multiplied by the Liquidation Grid (in basis points) in the corresponding tenor bucket. The total liquidation cost for the Treasury security sub-portfolio would then be a sum of the costs over all the buckets.
The Delta LC for the total portfolio would be simple sum of the Delta LCs over all sub-portfolios.
5. Concentration Charges
In addition to Vega and Delta LCs, the proposed model also would incorporate the potential risks involved in closing out large or concentrated positions in a portfolio. The “largeness” of an option position is typically measured in terms of Average Daily Volume (“ADV”). The Vega volume or notional, defined as “Vega-weighted ADV,” is also a relevant measure of options trading volume. Closing out large or concentrated positions with one or more Vega notional may either take longer to liquidate or demand wider spreads, and therefore could incur additional cost. To cover this additional risk, the proposed model would use Vega concentration factors (“Vega CF”) to scale the Vega LC for option positions. The Vega CFs would be equal to one for small positions that are less than one Vega notional, but may be scaled up for large positions as a function of the size of the positions. Similar to Vega CF, Delta concentration factors (“Delta CF”) would be used to scale the Delta LC to account for the concentration risk associated with large Delta positions.
6. Volatility Correlations
Under the proposed model, the Vega LC for each underlying sub-portfolio is calculated using correlations between the Vega buckets. The correlation matrix from the most liquid product (SPX) would be used as the base and would be scaled for other underlyings based on their liquidity class. These would be calibrated from time periods that overlap the stress periods used to calculate Liquidation Grids.
To aggregate the liquidation cost at the portfolio level, the pair-wise correlations of implied volatilities between different underlyings are needed. OCC would use a single correlation value for all cross-underlying correlations rather than a correlation matrix for all cross-underlying correlations to simplify the calibration of the grids. To account for potential errors that may arise from using a single correlation value, OCC would calculate three single correlations representing the minimum, average, and maximum correlation across the liquidity class to determine three different Vega LCs. The highest of these three Vega LCs would be used as the final Vega LC.
7. STANS Margin Floor
The proposed liquidation costs would be added to the base and stress margin components of STANS that are intended to cover the potential losses due to price movements over a two-day risk horizon. In certain cases, well-hedged portfolios may not experience any loss and the resultant STANS margin requirement is close to zero or may even become positive in some extreme cases. If the STANS requirement is positive, this may result in a credit instead of a charge for the Clearing Member. To account for the risk of potentially liquidating a portfolio at current (instead of two-day ahead) prices, no credit from the margin would be allowed so that the final margin requirement would not be lower than the amount of the liquidation cost.
8. Margin Policy and Stress Testing and Clearing Fund Methodology Description
OCC also would make conforming changes to its Margin Policy and Stress Testing and Clearing Fund Methodology Description to reflect the inclusion of the new liquidation cost charge as an add-on charge to the base STANS margin and how the liquidation cost Start Printed Page 23094charge add-on would be incorporated in Clearing Fund shortfall calculations.
Clearing Member Outreach
To inform Clearing Members of the proposed change, OCC has provided overviews of its proposed liquidation cost model to the Financial Risk Advisory Council (“FRAC”), a working group comprised of exchanges, Clearing Members and indirect participants of OCC, and the OCC Roundtable, which was established to bring Clearing Members, exchanges and OCC together to discuss industry and operational issues,
during 2016 and 2017. OCC has also published Information Memos to all Clearing Members discussing the proposed change.
Under the proposed liquidation cost model, each Clearing Member/account would independently observe different levels of impact based on the composition of their cleared portfolios. Based on OCC's analysis to-date, directional portfolios containing more outright positions, which are more typically associated with customer accounts, are most likely to see the largest impact from the proposed liquidation cost charges, while more well-hedged portfolios, such as market maker accounts, would be less impacted (and are more likely to incur the minimum liquidation cost charge). In the aggregate, OCC expects the proposed liquidation cost charges to make up approximately 5-8% of total risk margin charges, with customer accounts accounting for roughly 60% of the proposed liquidation cost charges, and proprietary accounts and market markers generating approximately 25% and 15% of the proposed liquidation cost charges, respectively.
Given the magnitude of expected changes in margins, OCC expects to conduct an extended parallel implementation for Clearing Members prior to implementation. Additionally, OCC will perform additional outreach to the FRAC upon submission of its regulatory filings to remind Clearing Members of the pending changes and direct outreach with those Clearing Members that would be most impacted by the proposed change and would work closely with such Clearing Members to coordinate the implementation and associated funding for such Clearing Members resulting from the proposed change.
OCC expects to implement the proposed changes no sooner than thirty (30) days and no later than one hundred eighty (180) days from the date that OCC receives all necessary regulatory approvals for the filings. OCC will announce the implementation date of the proposed change by an Information Memo posted to its public website at least two (2) weeks prior to implementation.
Expected Effect on and Management of Risk
OCC believes that the proposed change, which would introduce a new liquidation cost model into OCC's margin methodology, would reduce the overall level of risk to OCC, its Clearing Members, and the markets served by OCC. As described above, STANS margin requirements are comprised of the sum of several components, each reflecting a different aspect of risk. These margins are intended to cover the potential losses due to price movements over a two-day risk horizon; however, the base and stress margin components do not cover the potential liquidation cost OCC may incur in closing out a defaulted Clearing Member's portfolio. Closing out positions in a defaulted portfolio could entail selling longs at bid price and covering shorts at ask price. This means that additional liquidation costs may need to take into account the bid-ask price spreads. The proposed liquidation cost model would calculate liquidation costs for OCC's cleared products based on risk measures, gross contract volumes and market bid-ask spreads. The proposed model is designed to provide additional financial resources in the form of margin, based on liquidation costs and current market prices, to guard against potential shortfalls in margin requirements that may arise due to the costs of liquidating Clearing Member portfolios. OCC uses the margin it collects from a defaulting Clearing Member to protect other Clearing Members from losses they cannot anticipate or control as a result of such a default. As a result, OCC believes the proposed changes would reduce the overall level of risk to OCC, its Clearing Members, and the markets served by OCC.
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.
Section 805(a)(2) of the Clearing Supervision Act 
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 
states that the objectives and principles for risk management standards prescribed under Section 805(a) shall be to:
- 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 
and the risk management standards adopted by the Commission in Rule 17Ad-22 under the Act for the reasons set forth below.
OCC believes the proposed changes are consistent with the objectives and principles of Section 805(b) of the Clearing Supervision Act.
As described above, STANS margin requirements are comprised of the sum of several components, each reflecting a different aspect of risk. These margins are intended to cover the potential Start Printed Page 23095losses due to price movements over a two-day risk horizon; however, the base and stress margin components do not cover the potential liquidation cost OCC could incur in closing out a defaulted Clearing Member's portfolio. Closing out positions in a defaulted portfolio could entail selling longs at bid price and covering shorts at ask price. This means that additional liquidation costs may need to take into account the bid-ask price spreads. The proposed model is designed to provide additional financial resources in the form of margin to guard against potential shortfalls in margin requirements that may arise due to the costs of liquidating Clearing Member portfolios. OCC uses the margin it collects from a defaulting Clearing Member to protect other Clearing Members from losses as a result of the default. As a result, OCC believes the proposed change would promote robust risk management and safety and soundness while reducing systemic risks and would thereby support the stability of the broader financial system.
Rule 17Ad-22(b)(2) 
requires, in part, that a registered clearing agency that performs central counterparty services establish, implement, maintain and enforce written policies and procedures reasonably designed to use margin requirements to limit its credit exposures to participants under normal market conditions and use risk-based models and parameters to set margin requirements. As described above, the proposed liquidation cost model is a risk-based model that calculates liquidation cost based on risk measures, gross contract volumes, and market bid-ask spreads. The proposed model is designed to provide additional financial resources in the form of margin, based on liquidation costs and current market prices, to guard against potential shortfalls in margin requirements that may arise due to the costs of liquidating Clearing Member portfolios, which currently are not taken into account in STANS for all of OCC's cleared products. Accordingly, the proposed risk-based model would be used to calculate margin requirements designed to limit OCC's credit exposures to participants under normal market conditions in a manner consistent with Rule 17Ad-22(b)(2).
Rule 17Ad-22(e)(6)(i) 
further requires 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 considers, and produces margin levels commensurate with, the risks and particular attributes of each relevant product, portfolio, and market. The proposed liquidation cost model is a risk-based model that would calculate additional margin charges designed to account for potential shortfalls in margin requirements that may arise due to the costs of liquidating Clearing Member portfolios by taking into consideration the risks and attributes associated with relevant products and portfolios cleared by OCC (e.g., volatility bid-ask spreads, price bid-ask spreads, Vega notional, and Delta notional). Accordingly, OCC believes the proposed changes are consistent with Rule 17Ad-22(e)(6)(i).
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 the proposed change was filed with the Commission or (ii) the date any additional information requested by the Commission is received. OCC 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.
OCC 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.
