(a) Means of calculation.

(1) Each business day each covered swap entity shall calculate an initial margin amount to be collected from each covered counterparty using:

(i) A risk-based model that meets the requirements of paragraph (b) of this section; or

(ii) The table-based method set forth in paragraph (c) of this section.

(2) Each business day each covered swap entity shall calculate an initial margin amount to be posted with each financial end user with material swaps exposure using:

(i) A risk-based model that meets the requirements of paragraph (b) of this section; or

(ii) The table-based method set forth in paragraph (c) of this section.

(3) Each covered swap entity may reduce the amounts calculated pursuant to paragraphs (a)(1) and (2) of this section by the initial margin threshold amount provided that the reduction does not include any portion of the initial margin threshold amount already applied by the covered swap entity or its margin affiliates in connection with other uncleared swaps with the counterparty or its margin affiliates.

(4) The amounts calculated pursuant to paragraph (a)(3) of this section shall not be less than zero.

(5) A covered swap entity would be deemed to calculate initial margin as required by paragraph (a)(1) of this section if it uses the amount of initial margin calculated by a counterparty that is a swap entity and the initial margin amount is calculated using the swap entity's risk-based model that meets the requirements of paragraph (b) of this section or is approved by a prudential regulator, provided that initial margin calculated in such manner is used only with respect to uncleared swaps entered into by the covered swap entity and the swap entity for the purpose of hedging the covered swap entity's swaps with non-swap entity counterparties.

(b) Risk-based models

(1) Commission or registered futures association approval.

(i) A covered swap entity shall obtain the written approval of the Commission or a registered futures association to use a model to calculate the initial margin required in §§23.150 through 23.161.

(ii) A covered swap entity shall demonstrate that the model satisfies all of the requirements of this section on an ongoing basis.

(iii) A covered swap entity shall notify the Commission and the registered futures association in writing 60 days prior to:

(A) Extending the use of an initial margin model that has been approved to an additional product type;

(B) Making any change to any initial margin model that has been approved that would result in a material change in the covered swap entity's assessment of initial margin requirements; or

(C) Making any material change to modeling assumptions used by the initial margin model.

(iv) The Commission or the registered futures association may rescind approval of the use of any initial margin model, in whole or in part, or may impose additional conditions or requirements if the Commission or the registered futures association determines, in its discretion, that the model no longer complies with this section.

(2) Elements of the model.

(i) The initial margin model shall calculate an amount of initial margin that is equal to the potential future exposure of the uncleared swap or netting portfolio of uncleared swaps covered by an eligible master netting agreement. Potential future exposure is an estimate of the one-tailed 99 percent confidence interval for an increase in the value of the uncleared swap or netting portfolio of uncleared swaps due to an instantaneous price shock that is equivalent to a movement in all material underlying risk factors, including prices, rates, and spreads, over a holding period equal to the shorter of ten business days or the maturity of the swap or netting portfolio.

(ii) All data used to calibrate the initial margin model shall be based on an equally weighted historical observation period of at least one year and not more than five years and must incorporate a period of significant financial stress for each broad asset class that is appropriate to the uncleared swaps to which the initial margin model is applied.

(iii) The initial margin model shall use risk factors sufficient to measure all material price risks inherent in the transactions for which initial margin is being calculated. The risk categories shall include, but should not be limited to, foreign exchange or interest rate risk, credit risk, equity risk, and commodity risk, as appropriate. For material exposures in significant currencies and markets, modeling techniques shall capture spread and basis risk and shall incorporate a sufficient number of segments of the yield curve to capture differences in volatility and imperfect correlation of rates along the yield curve.

(iv) In the case of an uncleared cross-currency swap, the initial margin model need not recognize any risks or risk factors associated with the fixed, physically-settled foreign exchange transactions associated with the exchange of principal embedded in the uncleared cross-currency swap. The initial margin model must recognize all material risks and risk factors associated with all other payments and cash flows that occur during the life of the uncleared cross-currency swap.

(v) The initial margin model may calculate initial margin for an uncleared swap or netting portfolio of uncleared swaps covered by an eligible master netting agreement. It may reflect offsetting exposures, diversification, and other hedging benefits for uncleared swaps that are governed by the same eligible master netting agreement by incorporating empirical correlations within the following broad risk categories, provided the covered swap entity validates and demonstrates the reasonableness of its process for modeling and measuring hedging benefits: Commodity, credit, equity, and foreign exchange or interest rate. Empirical correlations under an eligible master netting agreement may be recognized by the model within each broad risk category, but not across broad risk categories.

(vi) If the initial margin model does not explicitly reflect offsetting exposures, diversification, and hedging benefits between subsets of uncleared swaps within a broad risk category, the covered swap entity shall calculate an amount of initial margin separately for each subset of uncleared swaps for which such relationships are explicitly recognized by the model. The sum of the initial margin amounts calculated for each subset of uncleared swaps within a broad risk category will be used to determine the aggregate initial margin due from the counterparty for the portfolio of uncleared swaps within the broad risk category.

(vii) The sum of the initial margin calculated for each broad risk category shall be used to determine the aggregate initial margin due from the counterparty.

(viii) The initial margin model shall not permit the calculation of any initial margin to be offset by, or otherwise take into account, any initial margin that may be owed or otherwise payable by the covered swap entity to the counterparty.

(ix) The initial margin model shall include all material risks arising from the nonlinear price characteristics of option positions or positions with embedded optionality and the sensitivity of the market value of the positions to changes in the volatility of the underlying rates, prices, or other material risk factors.

(x) The covered swap entity shall not omit any risk factor from the calculation of its initial margin that the covered swap entity uses in its model unless it has first demonstrated to the satisfaction of the Commission or the registered futures association that such omission is appropriate.

(xi) The covered swap entity shall not incorporate any proxy or approximation used to capture the risks of the covered swap entity's uncleared swaps unless it has first demonstrated to the satisfaction of the Commission or the registered futures association that such proxy or approximation is appropriate.

(xii) The covered swap entity shall have a rigorous and well-defined process for re-estimating, re-evaluating, and updating its internal margin models to ensure continued applicability and relevance.

(xiii) The covered swap entity shall review and, as necessary, revise the data used to calibrate the initial margin model at least annually, and more frequently as market conditions warrant, to ensure that the data incorporate a period of significant financial stress appropriate to the uncleared swaps to which the initial margin model is applied.

(xiv) The level of sophistication of the initial margin model shall be commensurate with the complexity of the swaps to which it is applied. In calculating an initial margin amount, the initial margin model may make use of any of the generally accepted approaches for modeling the risk of a single instrument or portfolio of instruments.

(xv) The Commission or the registered futures association may in its discretion require a covered swap entity using an initial margin model to collect a greater amount of initial margin than that determined by the covered swap entity's initial margin model if the Commission or the registered futures association determines that the additional collateral is appropriate due to the nature, structure, or characteristics of the covered swap entity's transaction(s) or is commensurate with the risks associated with the transaction(s).

(3) [Reserved]

(4) Periodic review. A covered swap entity shall periodically, but no less frequently than annually, review its initial margin model in light of developments in financial markets and modeling technologies, and enhance the initial margin model as appropriate to ensure that it continues to meet the requirements for approval in this section.

(5) Control, oversight, and validation mechanisms.

(i) The covered swap entity shall maintain a risk management unit in accordance with §23.600(c)(4)(i) that is independent from the business trading unit (as defined in §23.600).

(ii) The covered swap entity's risk control unit shall validate its initial margin model prior to implementation and on an ongoing basis. The covered swap entity's validation process shall be independent of the development, implementation, and operation of the initial margin model, or the validation process shall be subject to an independent review of its adequacy and effectiveness. The validation process shall include:

(A) An evaluation of the conceptual soundness of (including developmental evidence supporting) the initial margin model;

(B) An ongoing monitoring process that includes verification of processes and benchmarking by comparing the covered swap entity's initial margin model outputs (estimation of initial margin) with relevant alternative internal and external data sources or estimation techniques. The benchmark(s) must address the model's limitations. When applicable the covered swap entity should consider benchmarks that allow for non-normal distributions such as historical and Monte Carlo simulations. When applicable validation shall include benchmarking against observable margin standards to ensure that the initial margin required is not less than what a derivatives clearing organization would require for similar cleared transactions; and

(C) An outcomes analysis process that includes back testing the model. This analysis shall recognize and compensate for the challenges inherent in back testing over periods that do not contain significant financial stress.

(iii) If the validation process reveals any material problems with the model, the covered swap entity must promptly notify the Commission and the registered futures association of the problems, describe to the Commission and the registered futures association any remedial actions being taken, and adjust the model to ensure an appropriately conservative amount of required initial margin is being calculated.

(iv) In accordance with §23.600(e)(2), the covered swap entity shall have an internal audit function independent of the business trading unit and the risk management unit that at least annually assesses the effectiveness of the controls supporting the initial margin model measurement systems, including the activities of the business trading units and risk control unit, compliance with policies and procedures, and calculation of the covered swap entity's initial margin requirements under this part. At least annually, the internal audit function shall report its findings to the covered swap entity's governing body, senior management, and chief compliance officer.

(6) Documentation. The covered swap entity shall adequately document all material aspects of its model, including management and valuation of uncleared swaps to which it applies, the control, oversight, and validation of the initial margin model, any review processes and the results of such processes.

(7) Escalation procedures. The covered swap entity must adequately document—

(i) Internal authorization procedures, including escalation procedures, that require review and approval of any change to the initial margin calculation under the initial margin model;

(ii) Demonstrable analysis that any basis for any such change is consistent with the requirements of this section; and

(iii) Independent review of such demonstrable analysis and approval.

(c) Table-based method. If a model meeting the standards set forth in paragraph (b) of this section is not used, initial margin shall be calculated in accordance with this paragraph.

(1) Standardized initial margin schedule.

(2) Net to gross ratio adjustment.

(i) For multiple uncleared swaps subject to an eligible master netting agreement, the initial margin amount under the standardized table shall be computed according to this paragraph.

(ii) Initial Margin = 0.4 × Gross Initial Margin + 0.6 × Net-to-Gross Ratio × Gross Initial Margin, where:

(A) Gross Initial Margin = the sum of the product of each uncleared swap's effective notional amount and the gross initial margin requirement for all uncleared swaps subject to the eligible master netting agreement;

(B) Net-to-Gross Ratio = the ratio of the net current replacement cost to the gross current replacement cost;

(C) Gross Current Replacement cost = the sum of the replacement cost for each uncleared swap subject to the eligible master netting agreement for which the cost is positive; and

(D) Net Current Replacement Cost = the total replacement cost for all uncleared swaps subject to the eligible master netting agreement.

(E) In cases where the gross replacement cost is zero, the Net-to-Gross Ratio shall be set to 1.0.
