          - [Release No. 34-82473; File No. SR-OCC-2017-011]

                    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 December 28, 2017, The Options Clearing Corporation (“OCC”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I, II, and III below, which Items have been prepared by OCC. The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.                

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

                    The proposed rule change by OCC would formalize and update OCC's Model Risk Management Policy (“MRM Policy” or “Policy”) in connection with multiple requirements applicable to OCC under Rule 17Ad-22, including Rules 17Ad-22(b)(2) concerning margin requirements and (b)(4) concerning model validation as well as Rules 17Ad-22(e)(2) concerning governance, (e)(3) concerning frameworks for the comprehensive management of risks, and (e)(4)(vii), (e)(6)(vii) and (e)(7)(vii) concerning model validation.[3]                                          The MRM Policy is included as confidential Exhibit 5 of the filing. The Policy is being is submitted without marking to improve readability as it is being submitted in its entirety as new rule text.                

                    The proposed rule change does not require any changes to the text of OCC's By-Laws or Rules. All terms with initial capitalization that are not otherwise defined herein have the same meaning as set forth in the OCC By-Laws and Rules.[4] 

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

In its filing with the Commission, OCC included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. OCC has prepared summaries, set forth in sections (A), (B), and (C) below, of the most significant aspects of these statements.

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

#### (1) Purpose

#### Background

                    OCC's use of models inherently exposes OCC to model risk.[5]                                          To help manage this risk, OCC is proposing to formalize and update its MRM Policy, which sets forth the general framework for OCC's model risk management practices. The MRM Policy would apply to all Risk Models [6]                                          used by OCC to determine, quantify or measure actual or potential risk exposures or risk mitigating actions. The purpose of the MRM Policy is to ensure that OCC appropriately manages its model risks by clearly outlining the roles and responsibilities of OCC's (1) Quantitative Risk Management department (“QRM”), (2) Model Validation Group (“MVG”), and (3) Model Risk Working Group (“MRWG”) in model development, implementation, use, monitoring, and validation. The provisions of the MRM Policy addressing these core elements are described in greater detail below and are designed to ensure that OCC uses an appropriate approach to managing model risk. OCC notes that the MRM Policy is part of a broader framework regarding model risk management that is designed to further the appropriate                           ( print page 2272)                        design, validation and operation of OCC's Risk Models.[7] 

#### Model Risk Management Policy

#### Introduction

                    The MRM Policy would apply to all Risk Models used by OCC to determine, quantify or measure actual or potential risk exposures or risk mitigating actions. As noted above, Risk Models are defined under the Policy to be credit risk models (                    *e.g.,*                     models concerning OCC's Clearing Fund), margin system and related models (                    *e.g.,*                     OCC's System for Theoretical Analysis and Numerical Simulations or “STANS”), and liquidity risk models.                

                    The MRM Policy also would clarify that OCC considers a Risk Model to be any quantitative method or approach that applies statistical, economic, financial, or mathematical theories, techniques, and/or assumptions to process inputs into quantitative estimates, forecasts, or projections. A Risk Model can also be a quantitative method with inputs that are qualitative or based on business judgment.[8]                                          The MRM Policy also would define “Methodology” to mean a collection of Risk Models used to estimate financial risk exposures.                

                    To guide activities in this part of OCC's model risk framework, OCC shall primarily follow the                     *Supervisory Guidance on Model Risk Management*                     issued by the Board of Governors of the Federal Reserve System and the Office of the Comptroller of the Currency (April 4, 2011), as well as any applicable regulatory requirements.[9] 

The MRM Policy sets forth a governance structure for the allocation of roles and responsibilities for Risk Model development, implementation, use, monitoring, and validation among different groups and individuals, including OCC's Board, the Risk Committee of the Board (“Risk Committee”), management, and other OCC staff. These roles and responsibilities are described in further detail below.

#### Quantitative Risk Management

Under the proposed Policy, the Executive Vice President of OCC's Financial Risk Management department (“EVP-FRM”) would be responsible for (i) having staff with the requisite knowledge, skills, and expertise to perform model risk management activities necessary to the staffs' responsibilities and (ii) overseeing Risk Model development, implementation, monitoring, and use.

#### Risk Model Development

Under the proposed Policy, Risk Model development and implementation shall be conducted by QRM unless a third-party is otherwise engaged by QRM to develop a Risk Model. Where QRM does not develop a Risk Model, it shall oversee the development, implementation, and monitoring in accordance with the Risk Model Development Procedure.

The design, theory, and logic of each Risk Model used by OCC shall be described in a document maintained by QRM and shall take into consideration published literature and industry best practice, where it is available. The document shall include a description of the Risk Model, the intended purpose of the Risk Model, the motivation of the Risk Model assumptions, the test data supporting the Risk Model, the Risk Model limitations, and other details as outlined in OCC's Maintenance and Periodic Review of Methodology Procedure. QRM also would be responsible for describing each Risk Model Methodology in a Methodology document. Requirements for Methodology documentation shall be contained in the Maintenance and Periodic Review of Methodology Procedure. The EVP-FRM also shall review and, if appropriate, approve the Risk Model documentation. The EVP-FRM may delegate the responsibility for reviewing and approving such Risk Model documentation to the First Vice President, Quantitative Risk Management, who shall provide notice of any approval to the EVP-FRM.

#### Risk Model Implementation

                    Under the proposed MRM Policy, QRM would review, evaluate, and propose model changes (to include Model Defects,[10]                                          enhancements, and/or Decommissioning [11]                                          of a Risk Model) in accordance with the Model Implementation Procedure and OCC's Legal Services Policy (and related procedures). New products that are non-standard equity options/futures shall be reviewed by QRM according to the Model Implementation Procedure for determination as to whether or not a new Risk Model is required or if the use of an existing Risk Model is fit for purpose. QRM shall recommend approval to OCC's Model Risk Working Group (“MRWG”) [12]                                          in accordance with the Model Risk Working Group Procedure subsequent to effective challenge and approval by MVG.                

Under the Policy, QRM shall seek Legal department (“Legal”) review to determine if a new Risk Model or change to an existing Risk Model requires regulatory filing prior to implementation and use in accordance with OCC's Legal Services Policy and related procedures. OCC shall not implement or use such Risk Model until Legal provides a written notice to QRM and MVG that the Risk Model does not require any additional regulatory action prior to implementation and use or, if a regulatory filing is required, that all requisite filing and approvals are complete.

                    Under the proposed Policy, QRM shall implement new Risk Models and changes to existing Risk Models in accordance with the Risk Model Development Procedure and the Model Implementation Procedure. QRM shall be responsible for overseeing the quality assurance and related testing procedures required for implementation and/or Decommissioning of a Risk Model. Reporting and escalation to the MRWG shall be performed in accordance with the Model Risk Working Group Procedure. The MRWG shall review and, if appropriate, approve all new Risk Models, Material Changes [13]                                          to Risk                           ( print page 2273)                        Models, and proposals for Decommissioning Risk Models prior to submitting to the Management Committee for approval.                

                    Under the Policy, the Management Committee would be responsible for reviewing and approving each new Risk Model and each Material Change to a Risk Model prior to implementation and use. The Management Committee also would review and approve each proposal for Decommissioning a Risk Model. Each approval shall constitute a recommendation and be reported to the Risk Committee for further review and approval. The Risk Committee shall review and, if appropriate, approve each new Risk Model and each Material Change prior to implementation and use, except that Material Changes to OCC's margin and Clearing Fund methodologies shall be referred to the Board for review and, if appropriate, final approval, upon a recommendation from the Risk Committee. The Risk Committee also shall review and, if appropriate, approve the Decommissioning of a Risk Model prior to removing it from the Model Inventory.[14] 

#### Risk Model Monitoring

Pursuant to the proposed Policy, QRM shall monitor the use and performance of Risk Models according to the Model Backtesting Procedure, the Business Backtesting Procedure, and the Margin Model Parameter Review and Sensitivity Analysis Procedure. Monitoring shall be reasonably designed to determine if the Risk Model is accurate, reliable and robust, and to identify limitations. The results of monitoring also shall be used to evaluate the behavior of a Risk Model over a range of input values. Risk tolerance and associated key risk indicators would be maintained by QRM to measure and monitor model risk. These risk measures, in addition to monthly Risk Model parameter reviews shall be reported to the MRWG and escalated to the Management Committee and/or Risk Committee as necessary in accordance with the Model Risk Working Group Procedure.

#### Model Validation Group

Under the proposed Policy, the First Vice President of MVG shall have qualified staff with the requisite knowledge, skills, and expertise to perform validations in accordance with the Model Validation Procedure. MVG personnel responsible for validation shall be independent from, shall not report to, and shall otherwise be free from influence from OCC business areas involved in the development, implementation and operation of such Risk Models.

#### Annual Model Validation Plan

The First Vice President of MVG shall develop and maintain an Annual Model Validation Plan (“Annual Plan”). The Annual Plan, as defined in the Annual Model Validation Plan Procedure, is a schedule of Risk Model validations performed for all Risk Models on the Model Inventory. MVG's Annual Plan shall require all Risk Models on the Model Inventory to be validated no less than annually (where annually is defined as 12 months, or 365 days).

Pursuant to the proposed Policy, the Risk Committee shall review and approve the Annual Model Validation Plan and any removals or deferrals from the previously approved Annual Model Validation Plan based on recommendations from the Chief Risk Officer (“CRO”). In addition, the CRO shall provide a quarterly report to the Risk Committee that provides information on progress against the Annual Model Validation Plan.

#### Model Inventory

Pursuant to the proposed Policy, MVG shall maintain a complete and accurate inventory of Risk Models according to the Model Inventory Procedure. To ensure the Model Inventory is complete and accurate, MVG shall perform a firm-wide assessment on an annual basis in accordance with the Model Identification Procedure.

#### Independent Model Validation

                    Under the proposed Policy, MVG would be responsible for evaluating the performance of each Risk Model by performing Independent Model Validations [15]                                          in accordance with the Model Validation Procedure. Validations shall be performed according to the Model Validation Procedure, and shall include a review of Risk Model performance, parameters, and assumptions. Conclusions shall be formulated in the form of a “Model Assessment Report” and shall be reviewed by QRM upon conclusion of the report. MVG shall perform performance monitoring of Risk Models according to the Model Performance Monitoring Procedure. Findings from validations and performance monitoring shall be identified, monitored, remediated, and reported according to the Model Findings Management Procedure and presented to the Management Committee and Risk Committee in the form of a Model Risk Management Findings Dashboard.                

Pursuant to the proposed Policy, MVG shall validate all Risks Models prior to implementation and use in accordance with the Model Validation Procedure. Additionally, MVG shall review Material Changes to Risk Models prior to implementation of the Material Change and in accordance with the Model Implementation Procedure. MVG shall assign a model rating and model risk level to each Risk Model on the Model Inventory. The effectiveness of each Risk Model shall be reported by the CRO to the Risk Committee on a quarterly basis.

In the event a third-party validator is used to validate a Risk Model or in the event that OCC uses a third-party to develop a Risk Model, MVG shall oversee/perform the validation in accordance with the Model Validation Procedure. The CRO shall report results of third party validations of OCC's Risk Models and results of validations of third-party Risk Models to the Management Committee and Risk Committee along with any recommended actions and remediation plans associated with such validations.

#### Model Risk Working Group

Under the proposed Policy, the MRWG would be responsible for assisting OCC's Management Committee in overseeing and governing OCC's model-related risk issues. The MRWG consists of representatives from Financial Risk Management, QRM, MVG and Enterprise Risk Management as well as representatives from Legal to provide adequate support and Legal expertise as it relates to Model Risk. The MRWG shall serve as a resource by overseeing model risk, which includes, without limitation, ongoing model risk monitoring activities, approving, or recommending approval of new Risk Models and Material Changes to Risk Models, and tracking Model Defects and remediation activities as stipulated in the Model Risk Working Group Procedure.

#### Policy Updates Exceptions and Violations

                    Finally, pursuant to the proposed Policy, OCC's Management Committee shall review and approve the Policy on an annual basis and recommend approval of the Policy to the Risk                           ( print page 2274)                        Committee. The Management Committee also shall review and approve any material changes to the Policy and recommend further approval to the Risk Committee.                

                    The MRM Policy also would contain OCC's standard policy language concerning the policy exception and violation processes. Specifically, any request for an exception to the Policy must be made in writing to a member of the Office of the Executive Chairman,[16]                                          who is then responsible for reviewing the exception request and providing a decision in writing to the person requesting the exception. OCC's CRO, Chief Compliance Officer, or Chief Audit Executive may also request an exception to the Policy directly to the Board. All requests for exceptions and their dispositions would be reported to the Board or Risk Committee as appropriate no later than its next regularly scheduled meeting, in a format approved by the Chair of the Board or Risk Committee. In addition, Policy violations shall be reported to OCC's Chief Compliance Officer, or, if the violation involves the Compliance Department, to the head of Internal Audit or a member of the Office of the Executive Chairman.                

#### (2) Statutory Basis

                    Section 17A(b)(3)(F) of the Act [17]                                          requires, among other things, that the rules of a clearing agency be designed to assure the safeguarding of securities and funds in the custody or control of the clearing agency or for which it is responsible, and, in general, to protect investors and the public interest. As described in more detail above, OCC believes that formalizing the MRM Policy would help to ensure that OCC maintains policies and procedures that are reasonably designed to provide for a robust model risk management framework, which includes controls pertaining to the governance, development, implementation, use, monitoring, and Independent Model Validation of OCC's Risk Models. In this way, the Policy is intended to further the appropriate design, validation and operation of Risk Models within OCC's performance of clearance and settlement services. The MRM Policy thereby promotes, for example, the development, use and monitoring of appropriately conservative margin and Clearing Fund requirements. As a result, OCC believes the proposed rule change is designed to assure the safeguarding of securities and funds at OCC and, in general, protect investors and the public interest consistent with Section 17A(b)(3)(F) of the Act.[18] 

                    Rule 17Ad-22(e)(2) [19]                                          requires a covered clearing agency to establish, implement, maintain and enforce written policies and procedures reasonably designed to provide for governance arrangements that, among other things: (i) Are clear and transparent; (ii) clearly prioritize safety and efficiency of the covered clearing agency; (iii) support the public interest requirements in Section 17A of the Act [20]                                          applicable to clearing agencies, and the objectives of owners and participants; and (iv) specify clear and direct lines of responsibility. The proposed Policy would describe, in detail, OCC's overall framework for Risk Model governance. This includes establishing clear, transparent, and direct responsibilities for OCC's Board, Risk Committee, management, and other OCC staff in connection with OCC's model risk management framework and how the relevant groups and individuals interact. In particular, the proposed Policy is designed to establish appropriate governance arrangements for the development, implementation, use, monitoring, and Independent Model Validation of OCC's Risk Models. OCC believes that these governance arrangements prioritize the safety and efficiency of OCC and support the public interest requirements of the Act by describing specifies roles, responsibilities and requirements for OCC's model testing, monitoring, validation, and review processes, thereby helping to ensure that OCC maintains a robust framework for managing its model risk.                

                    Rule 17Ad-22(e)(3)(i) [21]                                          requires a covered clearing agency to establish, implement, maintain, and enforce written policies and procedures reasonably designed to, among other things, maintain a sound risk management framework for comprehensively managing its risks, which includes risk management policies, procedures, and systems designed to identify, measure, monitor, and manage such risks and that are subject to review on a specified periodic basis and approved by its Board annually. OCC believes the proposed Policy is consistent with Rule 17Ad-22(e)(3)(i) [22]                                          because it is an essential component of OCC's overall framework for comprehensively managing its risks, which includes model risk. Specifically, OCC believes the proposed Policy is reasonably designed to identify, measure, monitor, and manage model risks by providing a sound framework for defining, developing, maintaining, and validating OCC's Risk Models and for making any changes necessary to ensure those Risk Models continue to address relevant risks appropriately. As noted above, the proposed Policy provides that OCC's QRM staff, as part of model risk management and model development, are responsible for monitoring model performance on a continuous basis. Specifically, QRM staff would monitor OCC's Risk Models to determine whether such models perform as intended and are accurate, reliable and robust and to identify any Risk Model limitations. The results of monitoring also shall be used to evaluate the behavior of a Risk Model over a range of input values. Moreover, the proposed Policy describes MVG's obligations for the independent validation of new Risk Models, Material Changes to Risk Models, and the annual validation of Risk Models.                

                    Rules 17Ad-22(e)(4)(vii), (e)(6)(vii) and (e)(7)(vii) [23]                                          require a covered clearing agency establish, implement, maintain and enforce written policies and procedures reasonably designed to perform independent model validations on its credit risk models, margin models, and liquidity risk models not less than annually or more frequently as may be contemplated by the clearing agency's risk management framework. OCC believes the proposed rule change is consistent with Rules 17Ad-22(e)(4)(vii), (e)(6)(vii) and (e)(7)(vii) [24]                                          because the Policy would require OCC to perform an Independent Model Validation of its Risk Models on at least an annual basis, or more frequently as needed, and prior to the implementation of new Risk Models or Material Changes to Risk Models. OCC also believes that the proposed rule change is consistent with the requirement in Rule 17Ad-22(b)(4) [25]                                          that OCC's policies and procedures be reasonably designed to provide for an annual model validation of OCC's margin models, that evaluates their performance and the related                           ( print page 2275)                        parameters and assumptions, by a qualified person who is free from influence from the persons responsible for the development or operation of the models being validated. As noted above, the proposed Policy provides that OCC's model validation staff reviews each Risk Model in OCC's inventory, including margin models, at least annually and such staff is removed from the primary development path of a model to preserve its ability to provide an independent assessment.                

                    Finally, Rule 17Ad-22(b)(2) [26]                                          requires, in part, that a registered clearing agency establish, implement, maintain and enforce written policies and procedures reasonably designed to use risk-based models and parameters to set margin requirements. OCC believes that the proposed Policy would provide for clear identification of its risk-based models and thereby promote compliance with the requirement in Rule 17Ad-22(b)(2) [27]                                          that OCC's policies and procedures be reasonably designed to use risk-based models and parameters to set margin requirements.                

The proposed rule change is not inconsistent with the existing rules of OCC, including any other rules proposed to be amended.

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

                    Section 17A(b)(3)(I) of the Act [28]                                          requires that the rules of a clearing agency not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act. OCC does not believe that the proposed rule change would impact or impose any burden on competition. The proposed rule change addresses OCC's internal framework surrounding the governance, development, implementation, use, monitoring, and validation of Risk Models. Under this framework, OCC's controls regarding the design, use, implementation and validation of models, as set forth in the proposed Policy, insofar as they affect margin or Clearing Fund requirements, would have an equal impact on all Clearing Members. Consequently, the proposed Policy does not provide any Clearing Member with a competitive advantage over any other Clearing Member. Further, the proposed rule change would not affect any Clearing Member's access to OCC's services or impose any direct burdens on Clearing Members. Accordingly, the proposed rule change would not unfairly inhibit access to OCC's services or disadvantage or favor any particular user in relationship to another user.                

For the foregoing reasons, OCC believes that the proposed rule change is in the public interest, would be consistent with the requirements of the Act applicable to clearing agencies, and would not impact or impose a burden on competition.

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

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

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

                    Within 45 days of the date of publication of this notice in the                     **Federal Register**                     or within such longer period up to 90 days (i) as the Commission may designate if it finds such longer period to be appropriate and publishes its reasons for so finding or (ii) as to which the self-regulatory organization consents, the Commission will:                

(A) By order approve or disapprove the proposed rule change, or

(B) institute proceedings to determine whether the proposed rule change should be disapproved.

7.                             For example, OCC's Margin Policy is also part of OCC's framework regarding model risk management in that it is designed to be consistent with the requirement in Rule 17Ad-22(e)(6)(vii) that OCC's policies and procedures provide for a risk-based margin system that requires a margin model validation not less than annually.                         *See*17 CFR 240.17Ad-22(e)(6)(vii).
