Amendment ## 12 CFR--PART 217View Printed Federal Register page 85 FR 4419 in PDF format.## Amendment(s) published January 24, 2020, in 85 FR 4419Effective Dates: Apr. 1, 2020 22. Section 217.132 is amended by: a. Revising paragraphs (b)(2)(ii)(A)(3) through (5); b. Adding paragraphs (b)(2)(ii)(A)(6) and (7); c. Revising paragraphs (c) heading and (c)(1) and (2) and (5) through (8); d. Adding paragraphs (c)(9) through (11); e. Revising paragraph (d)(10)(i); f. In paragraphs (e)(5)(i)(A) and (H), removing “Table 3 to §217.132” and adding in its place “Table 4 to this section”; g. In paragraphs (e)(5)(i)(C) and (e)(6)(i)(B), removing “current exposure methodology” and adding in its place “standardized approach to counterparty credit risk” wherever it appears; h. Redesignating Table 3 to §217.132 following paragraph (e)(5)(ii) as Table 4 to §217.132; and i. Revising paragraph (e)(6)(viii). The revisions and additions read as follows: ## §217.132 Counterparty credit risk of repo-style transactions, eligible margin loans, and OTC derivative contracts.## * * * * *(b) * * * (2) * * * (ii) * * * (A) * * * (3) For repo-style transactions and client-facing derivative transactions, a Board-regulated institution may multiply the supervisory haircuts provided in paragraphs (b)(2)(ii)(A)(1) and (2) of this section by the square root of 1⁄2 (which equals 0.707107). If the Board-regulated institution determines that a longer holding period is appropriate for client-facing derivative transactions, then it must use a larger scaling factor to adjust for the longer holding period pursuant to paragraph (b)(2)(ii)(A)(6) of this section. (4) A Board-regulated institution must adjust the supervisory haircuts upward on the basis of a holding period longer than ten business days (for eligible margin loans) or five business days (for repo-style transactions), using the formula provided in paragraph (b)(2)(ii)(A)(6) of this section where the conditions in this paragraph (b)(2)(ii)(A)(4) apply. If the number of trades in a netting set exceeds 5,000 at any time during a quarter, a Board-regulated institution must adjust the supervisory haircuts upward on the basis of a minimum holding period of twenty business days for the following quarter (except when a Board-regulated institution is calculating EAD for a cleared transaction under §217.133). If a netting set contains one or more trades involving illiquid collateral, a Board-regulated institution must adjust the supervisory haircuts upward on the basis of a minimum holding period of twenty business days. If over the two previous quarters more than two margin disputes on a netting set have occurred that lasted longer than the holding period, then the Board-regulated institution must adjust the supervisory haircuts upward for that netting set on the basis of a minimum holding period that is at least two times the minimum holding period for that netting set. (5)(i) A Board-regulated institution must adjust the supervisory haircuts upward on the basis of a holding period longer than ten business days for collateral associated with derivative contracts (five business days for client-facing derivative contracts) using the formula provided in paragraph (b)(2)(ii)(A)(6) of this section where the conditions in this paragraph (b)(2)(ii)(A)(5)(i) apply. For collateral associated with a derivative contract that is within a netting set that is composed of more than 5,000 derivative contracts that are not cleared transactions, a Board-regulated institution must use a minimum holding period of twenty business days. If a netting set contains one or more trades involving illiquid collateral or a derivative contract that cannot be easily replaced, a Board-regulated institution must use a minimum holding period of twenty business days. (ii) Notwithstanding paragraph (b)(2)(ii)(A)(1) or (3) or (b)(2)(ii)(A)(5)(i) of this section, for collateral associated with a derivative contract in a netting set under which more than two margin disputes that lasted longer than the holding period occurred during the two previous quarters, the minimum holding period is twice the amount provided under paragraph (b)(2)(ii)(A)(1) or (3) or (b)(2)(ii)(A)(5)(i) of this section. (6) A Board-regulated institution must adjust the standard supervisory haircuts upward, pursuant to the adjustments provided in paragraphs (b)(2)(ii)(A)(3) through (5) of this section, using the following formula:
Where: TM equals a holding period of longer than 10 business days for eligible margin loans and derivative contracts other than client-facing derivative transactions or longer than 5 business days for repo-style transactions and client-facing derivative transactions; Hs equals the standard supervisory haircut; and Ts equals 10 business days for eligible margin loans and derivative contracts other than client-facing derivative transactions or 5 business days for repo-style transactions and client-facing derivative transactions. (7) If the instrument a Board-regulated institution has lent, sold subject to repurchase, or posted as collateral does not meet the definition of financial collateral, the Board-regulated institution must use a 25.0 percent haircut for market price volatility (Hs). ## * * * * *(c) EAD for derivative contracts—(1) Options for determining EAD. A Board-regulated institution must determine the EAD for a derivative contract using the standardized approach for counterparty credit risk (SA-CCR) under paragraph (c)(5) of this section or using the internal models methodology described in paragraph (d) of this section. If a Board-regulated institution elects to use SA-CCR for one or more derivative contracts, the exposure amount determined under SA-CCR is the EAD for the derivative contract or derivatives contracts. A Board-regulation institution must use the same methodology to calculate the exposure amount for all its derivative contracts and may change its election only with prior approval of the Board. A Board-regulated institution may reduce the EAD calculated according to paragraph (c)(5) of this section by the credit valuation adjustment that the Board-regulated institution has recognized in its balance sheet valuation of any derivative contracts in the netting set. For purposes of this paragraph (c)(1), the credit valuation adjustment does not include any adjustments to common equity tier 1 capital attributable to changes in the fair value of the Board-regulated institution's liabilities that are due to changes in its own credit risk since the inception of the transaction with the counterparty. (2) Definitions. For purposes of this paragraph (c) of this section, the following definitions apply: (i) End date means the last date of the period referenced by an interest rate or credit derivative contract or, if the derivative contract references another instrument, by the underlying instrument, except as otherwise provided in paragraph (c) of this section. (ii) Start date means the first date of the period referenced by an interest rate or credit derivative contract or, if the derivative contract references the value of another instrument, by underlying instrument, except as otherwise provided in paragraph (c) of this section. (iii) Hedging set means: (A) With respect to interest rate derivative contracts, all such contracts within a netting set that reference the same reference currency; (B) With respect to exchange rate derivative contracts, all such contracts within a netting set that reference the same currency pair; (C) With respect to credit derivative contract, all such contracts within a netting set; (D) With respect to equity derivative contracts, all such contracts within a netting set; (E) With respect to a commodity derivative contract, all such contracts within a netting set that reference one of the following commodity categories: Energy, metal, agricultural, or other commodities; (F) With respect to basis derivative contracts, all such contracts within a netting set that reference the same pair of risk factors and are denominated in the same currency; or (G) With respect to volatility derivative contracts, all such contracts within a netting set that reference one of interest rate, exchange rate, credit, equity, or commodity risk factors, separated according to the requirements under paragraphs (c)(2)(iii)(A) through (E) of this section. (H) If the risk of a derivative contract materially depends on more than one of interest rate, exchange rate, credit, equity, or commodity risk factors, the Board may require a Board-regulated institution to include the derivative contract in each appropriate hedging set under paragraphs (c)(1)(iii)(A) through (E) of this section. ## * * * * *(5) Exposure amount. (i) The exposure amount of a netting set, as calculated under paragraph (c) of this section, is equal to 1.4 multiplied by the sum of the replacement cost of the netting set, as calculated under paragraph (c)(6) of this section, and the potential future exposure of the netting set, as calculated under paragraph (c)(7) of this section. (ii) Notwithstanding the requirements of paragraph (c)(5)(i) of this section, the exposure amount of a netting set subject to a variation margin agreement, excluding a netting set that is subject to a variation margin agreement under which the counterparty to the variation margin agreement is not required to post variation margin, is equal to the lesser of the exposure amount of the netting set calculated under paragraph (c)(5)(i) of this section and the exposure amount of the netting set calculated under paragraph (c)(5)(i) of this section as if the netting set were not subject to a variation margin agreement. (iii) Notwithstanding the requirements of paragraph (c)(5)(i) of this section, the exposure amount of a netting set that consists of only sold options in which the premiums have been fully paid by the counterparty to the options and where the options are not subject to a variation margin agreement is zero. (iv) Notwithstanding the requirements of paragraph (c)(5)(i) of this section, the exposure amount of a netting set in which the counterparty is a commercial end-user is equal to the sum of replacement cost, as calculated under paragraph (c)(6) of this section, and the potential future exposure of the netting set, as calculated under paragraph (c)(7) of this section. (v) For purposes of the exposure amount calculated under paragraph (c)(5)(i) of this section and all calculations that are part of that exposure amount, a Board-regulated institution may elect to treat a derivative contract that is a cleared transaction that is not subject to a variation margin agreement as one that is subject to a variation margin agreement, if the derivative contract is subject to a requirement that the counterparties make daily cash payments to each other to account for changes in the fair value of the derivative contract and to reduce the net position of the contract to zero. If a Board-regulated institution makes an election under this paragraph (c)(5)(v) for one derivative contract, it must treat all other derivative contracts within the same netting set that are eligible for an election under this paragraph (c)(5)(v) as derivative contracts that are subject to a variation margin agreement. (vi) For purposes of the exposure amount calculated under paragraph (c)(5)(i) of this section and all calculations that are part of that exposure amount, a Board-regulated institution may elect to treat a credit derivative contract, equity derivative contract, or commodity derivative contract that references an index as if it were multiple derivative contracts each referencing one component of the index. (6) Replacement cost of a netting set—(i) Netting set subject to a variation margin agreement under which the counterparty must post variation margin. The replacement cost of a netting set subject to a variation margin agreement, excluding a netting set that is subject to a variation margin agreement under which the counterparty is not required to post variation margin, is the greater of: (A) The sum of the fair values (after excluding any valuation adjustments) of the derivative contracts within the netting set less the sum of the net independent collateral amount and the variation margin amount applicable to such derivative contracts; (B) The sum of the variation margin threshold and the minimum transfer amount applicable to the derivative contracts within the netting set less the net independent collateral amount applicable to such derivative contracts; or (C) Zero. (ii) Netting sets not subject to a variation margin agreement under which the counterparty must post variation margin. The replacement cost of a netting set that is not subject to a variation margin agreement under which the counterparty must post variation margin to the Board-regulated institution is the greater of: (A) The sum of the fair values (after excluding any valuation adjustments) of the derivative contracts within the netting set less the sum of the net independent collateral amount and variation margin amount applicable to such derivative contracts; or (B) Zero. (iii) Multiple netting sets subject to a single variation margin agreement. Notwithstanding paragraphs (c)(6)(i) and (ii) of this section, the replacement cost for multiple netting sets subject to a single variation margin agreement must be calculated according to paragraph (c)(10)(i) of this section. (iv) Netting set subject to multiple variation margin agreements or a hybrid netting set. Notwithstanding paragraphs (c)(6)(i) and (ii) of this section, the replacement cost for a netting set subject to multiple variation margin agreements or a hybrid netting set must be calculated according to paragraph (c)(11)(i) of this section. (7) Potential future exposure of a netting set. The potential future exposure of a netting set is the product of the PFE multiplier and the aggregated amount. (i) PFE multiplier. The PFE multiplier is calculated according to the following formula:
Where: V is the sum of the fair values (after excluding any valuation adjustments) of the derivative contracts within the netting set; C is the sum of the net independent collateral amount and the variation margin amount applicable to the derivative contracts within the netting set; and A is the aggregated amount of the netting set. (ii) Aggregated amount. The aggregated amount is the sum of all hedging set amounts, as calculated under paragraph (c)(8) of this section, within a netting set. (iii) Multiple netting sets subject to a single variation margin agreement. Notwithstanding paragraphs (c)(7)(i) and (ii) of this section and when calculating the potential future exposure for purposes of total leverage exposure under §217.10(c)(4)(ii)(B)(2), the potential future exposure for multiple netting sets subject to a single variation margin agreement must be calculated according to paragraph (c)(10)(ii) of this section. (iv) Netting set subject to multiple variation margin agreements or a hybrid netting set. Notwithstanding paragraphs (c)(7)(i) and (ii) of this section and when calculating the potential future exposure for purposes of total leverage exposure under §217.10(c)(4)(ii)(B)(2), the potential future exposure for a netting set subject to multiple variation margin agreements or a hybrid netting set must be calculated according to paragraph (c)(11)(ii) of this section. (8) Hedging set amount—(i) Interest rate derivative contracts. To calculate the hedging set amount of an interest rate derivative contract hedging set, a Board-regulated institution may use either of the formulas provided in paragraphs (c)(8)(i)(A) and (B) of this section: (A) Formula 1 is as follows: (B) Formula 2 is as follows: Hedging set amount = |AddOnIRTB1| + |AddOnIRTB2| + |AddOnIRTB3|. Where in paragraphs (c)(8)(i)(A) and (B) of this section: AddOnIRTB1 is the sum of the adjusted derivative contract amounts, as calculated under paragraph (c)(9) of this section, within the hedging set with an end date of less than one year from the present date; AddOnIRTB2 is the sum of the adjusted derivative contract amounts, as calculated under paragraph (c)(9) of this section, within the hedging set with an end date of one to five years from the present date; and AddOnIRTB3 is the sum of the adjusted derivative contract amounts, as calculated under paragraph (c)(9) of this section, within the hedging set with an end date of more than five years from the present date. (ii) Exchange rate derivative contracts. For an exchange rate derivative contract hedging set, the hedging set amount equals the absolute value of the sum of the adjusted derivative contract amounts, as calculated under paragraph (c)(9) of this section, within the hedging set. (iii) Credit derivative contracts and equity derivative contracts. The hedging set amount of a credit derivative contract hedging set or equity derivative contract hedging set within a netting set is calculated according to the following formula:
Where: k is each reference entity within the hedging set. K is the number of reference entities within the hedging set. AddOn(Refk) equals the sum of the adjusted derivative contract amounts, as determined under paragraph (c)(9) of this section, for all derivative contracts within the hedging set that reference reference entity k. ρk equals the applicable supervisory correlation factor, as provided in Table 2 to this section. (iv) Commodity derivative contracts. The hedging set amount of a commodity derivative contract hedging set within a netting set is calculated according to the following formula:
Where: k is each commodity type within the hedging set. K is the number of commodity types within the hedging set. AddOn(Typek) equals the sum of the adjusted derivative contract amounts, as determined under paragraph (c)(9) of this section, for all derivative contracts within the hedging set that reference reference commodity type. ρ equals the applicable supervisory correlation factor, as provided in Table 2 to this section. (v) Basis derivative contracts and volatility derivative contracts. Notwithstanding paragraphs (c)(8)(i) through (iv) of this section, a Board-regulated institution must calculate a separate hedging set amount for each basis derivative contract hedging set and each volatility derivative contract hedging set. A Board-regulated institution must calculate such hedging set amounts using one of the formulas under paragraphs (c)(8)(i) through (iv) that corresponds to the primary risk factor of the hedging set being calculated. (9) Adjusted derivative contract amount—(i) Summary. To calculate the adjusted derivative contract amount of a derivative contract, a Board-regulated institution must determine the adjusted notional amount of derivative contract, pursuant to paragraph (c)(9)(ii) of this section, and multiply the adjusted notional amount by each of the supervisory delta adjustment, pursuant to paragraph (c)(9)(iii) of this section, the maturity factor, pursuant to paragraph (c)(9)(iv) of this section, and the applicable supervisory factor, as provided in Table 2 to this section. (ii) Adjusted notional amount. (A)(1) For an interest rate derivative contract or a credit derivative contract, the adjusted notional amount equals the product of the notional amount of the derivative contract, as measured in U.S. dollars using the exchange rate on the date of the calculation, and the supervisory duration, as calculated by the following formula:
Where: S is the number of business days from the present day until the start date of the derivative contract, or zero if the start date has already passed; and E is the number of business days from the present day until the end date of the derivative contract. (2) For purposes of paragraph (c)(9)(ii)(A)(1) of this section: (i) For an interest rate derivative contract or credit derivative contract that is a variable notional swap, the notional amount is equal to the time-weighted average of the contractual notional amounts of such a swap over the remaining life of the swap; and (ii) For an interest rate derivative contract or a credit derivative contract that is a leveraged swap, in which the notional amount of all legs of the derivative contract are divided by a factor and all rates of the derivative contract are multiplied by the same factor, the notional amount is equal to the notional amount of an equivalent unleveraged swap. (B)(1) For an exchange rate derivative contract, the adjusted notional amount is the notional amount of the non-U.S. denominated currency leg of the derivative contract, as measured in U.S. dollars using the exchange rate on the date of the calculation. If both legs of the exchange rate derivative contract are denominated in currencies other than U.S. dollars, the adjusted notional amount of the derivative contract is the largest leg of the derivative contract, as measured in U.S. dollars using the exchange rate on the date of the calculation. (2) Notwithstanding paragraph (c)(9)(ii)(B)(1) of this section, for an exchange rate derivative contract with multiple exchanges of principal, the Board-regulated institution must set the adjusted notional amount of the derivative contract equal to the notional amount of the derivative contract multiplied by the number of exchanges of principal under the derivative contract. (C)(1) For an equity derivative contract or a commodity derivative contract, the adjusted notional amount is the product of the fair value of one unit of the reference instrument underlying the derivative contract and the number of such units referenced by the derivative contract. (2) Notwithstanding paragraph (c)(9)(ii)(C)(1) of this section, when calculating the adjusted notional amount for an equity derivative contract or a commodity derivative contract that is a volatility derivative contract, the Board-regulated institution must replace the unit price with the underlying volatility referenced by the volatility derivative contract and replace the number of units with the notional amount of the volatility derivative contract. (iii) Supervisory delta adjustments. (A) For a derivative contract that is not an option contract or collateralized debt obligation tranche, the supervisory delta adjustment is 1 if the fair value of the derivative contract increases when the value of the primary risk factor increases and −1 if the fair value of the derivative contract decreases when the value of the primary risk factor increases. (B)(1) For a derivative contract that is an option contract, the supervisory delta adjustment is determined by the following formulas, as applicable: (2) As used in the formulas in Table 2 to this section: (i) &PHgr; is the standard normal cumulative distribution function; (ii) P equals the current fair value of the instrument or risk factor, as applicable, underlying the option; (iii) K equals the strike price of the option; (iv) T equals the number of business days until the latest contractual exercise date of the option; (v) λ equals zero for all derivative contracts except interest rate options for the currencies where interest rates have negative values. The same value of λ must be used for all interest rate options that are denominated in the same currency. To determine the value of λ for a given currency, a Board-regulated institution must find the lowest value L of P and K of all interest rate options in a given currency that the Board-regulated institution has with all counterparties. Then, λ is set according to this formula:λ = max{−L + 0.1%, 0}; and (vi) σ equals the supervisory option volatility, as provided in Table 3 to this section. (C)(1) For a derivative contract that is a collateralized debt obligation tranche, the supervisory delta adjustment is determined by the following formula: (2) As used in the formula in paragraph (c)(9)(iii)(C)(1) of this section: (i) A is the attachment point, which equals the ratio of the notional amounts of all underlying exposures that are subordinated to the Board-regulated institution's exposure to the total notional amount of all underlying exposures, expressed as a decimal value between zero and one;30 30In the case of a first-to-default credit derivative, there are no underlying exposures that are subordinated to the Board-regulated institution's exposure. In the case of a second-or-subsequent-to-default credit derivative, the smallest (n−1) notional amounts of the underlying exposures are subordinated to the Board-regulated institution's exposure. (ii) D is the detachment point, which equals one minus the ratio of the notional amounts of all underlying exposures that are senior to the Board-regulated institution's exposure to the total notional amount of all underlying exposures, expressed as a decimal value between zero and one; and (iii) The resulting amount is designated with a positive sign if the collateralized debt obligation tranche was purchased by the Board-regulated institution and is designated with a negative sign if the collateralized debt obligation tranche was sold by the Board-regulated institution. (iv) Maturity factor. (A)(1) The maturity factor of a derivative contract that is subject to a variation margin agreement, excluding derivative contracts that are subject to a variation margin agreement under which the counterparty is not required to post variation margin, is determined by the following formula: Where MPOR refers to the period from the most recent exchange of collateral covering a netting set of derivative contracts with a defaulting counterparty until the derivative contracts are closed out and the resulting market risk is re-hedged. (2) Notwithstanding paragraph (c)(9)(iv)(A)(1) of this section: (i) For a derivative contract that is not a client-facing derivative transaction, MPOR cannot be less than ten business days plus the periodicity of re-margining expressed in business days minus one business day; (ii) For a derivative contract that is a client-facing derivative transaction, cannot be less than five business days plus the periodicity of re-margining expressed in business days minus one business day; and (iii) For a derivative contract that is within a netting set that is composed of more than 5,000 derivative contracts that are not cleared transactions, or a netting set that contains one or more trades involving illiquid collateral or a derivative contract that cannot be easily replaced, MPOR cannot be less than twenty business days. (3) Notwithstanding paragraphs (c)(9)(iv)(A)(1) and (2) of this section, for a netting set subject to two or more outstanding disputes over margin that lasted longer than the MPOR over the previous two quarters, the applicable floor is twice the amount provided in (c)(9)(iv)(A)(1) and (2) of this section. (B) The maturity factor of a derivative contract that is not subject to a variation margin agreement, or derivative contracts under which the counterparty is not required to post variation margin, is determined by the following formula: Where M equals the greater of 10 business days and the remaining maturity of the contract, as measured in business days. (C) For purposes of paragraph (c)(9)(iv) of this section, if a Board-regulated institution has elected pursuant to paragraph (c)(5)(v) of this section to treat a derivative contract that is a cleared transaction that is not subject to a variation margin agreement as one that is subject to a variation margin agreement, the Board-regulated institution must treat the derivative contract as subject to a variation margin agreement with maturity factor as determined according to (c)(9)(iv)(A) of this section, and daily settlement does not change the end date of the period referenced by the derivative contract. (v) Derivative contract as multiple effective derivative contracts. A Board-regulated institution must separate a derivative contract into separate derivative contracts, according to the following rules: (A) For an option where the counterparty pays a predetermined amount if the value of the underlying asset is above or below the strike price and nothing otherwise (binary option), the option must be treated as two separate options. For purposes of paragraph (c)(9)(iii)(B) of this section, a binary option with strike K must be represented as the combination of one bought European option and one sold European option of the same type as the original option (put or call) with the strikes set equal to 0.95 * K and 1.05 * K so that the payoff of the binary option is reproduced exactly outside the region between the two strikes. The absolute value of the sum of the adjusted derivative contract amounts of the bought and sold options is capped at the payoff amount of the binary option. (B) For a derivative contract that can be represented as a combination of standard option payoffs (such as collar, butterfly spread, calendar spread, straddle, and strangle), a Board-regulated institution must treat each standard option component as a separate derivative contract. (C) For a derivative contract that includes multiple-payment options, (such as interest rate caps and floors), a Board-regulated institution may represent each payment option as a combination of effective single-payment options (such as interest rate caplets and floorlets). (D) A Board-regulated institution may not decompose linear derivative contracts (such as swaps) into components. (10) Multiple netting sets subject to a single variation margin agreement—(i) Calculating replacement cost. Notwithstanding paragraph (c)(6) of this section, a Board-regulated institution shall assign a single replacement cost to multiple netting sets that are subject to a single variation margin agreement under which the counterparty must post variation margin, calculated according to the following formula: Replacement Cost = max{ΣNSmax{VNS; 0} − max{CMA; 0}; 0} + max{ΣNSmin{VNS; 0} − min{CMA; 0}; 0} Where: NS is each netting set subject to the variation margin agreement MA; VNS is the sum of the fair values (after excluding any valuation adjustments) of the derivative contracts within the netting set NS; and CMA is the sum of the net independent collateral amount and the variation margin amount applicable to the derivative contracts within the netting sets subject to the single variation margin agreement. (ii) Calculating potential future exposure. Notwithstanding paragraph (c)(5) of this section, a Board-regulated institution shall assign a single potential future exposure to multiple netting sets that are subject to a single variation margin agreement under which the counterparty must post variation margin equal to the sum of the potential future exposure of each such netting set, each calculated according to paragraph (c)(7) of this section as if such nettings sets were not subject to a variation margin agreement. (11) Netting set subject to multiple variation margin agreements or a hybrid netting set—(i) Calculating replacement cost. To calculate replacement cost for either a netting set subject to multiple variation margin agreements under which the counterparty to each variation margin agreement must post variation margin, or a netting set composed of at least one derivative contract subject to variation margin agreement under which the counterparty must post variation margin and at least one derivative contract that is not subject to such a variation margin agreement, the calculation for replacement cost is provided under paragraph (c)(6)(i) of this section, except that the variation margin threshold equals the sum of the variation margin thresholds of all variation margin agreements within the netting set and the minimum transfer amount equals the sum of the minimum transfer amounts of all the variation margin agreements within the netting set. (ii) Calculating potential future exposure. (A) To calculate potential future exposure for a netting set subject to multiple variation margin agreements under which the counterparty to each variation margin agreement must post variation margin, or a netting set composed of at least one derivative contract subject to variation margin agreement under which the counterparty to the derivative contract must post variation margin and at least one derivative contract that is not subject to such a variation margin agreement, a Board-regulated institution must divide the netting set into sub-netting sets (as described in paragraph (c)(11)(ii)(B) of this section) and calculate the aggregated amount for each sub-netting set. The aggregated amount for the netting set is calculated as the sum of the aggregated amounts for the sub-netting sets. The multiplier is calculated for the entire netting set. (B) For purposes of paragraph (c)(11)(ii)(A) of this section, the netting set must be divided into sub-netting sets as follows: (1) All derivative contracts within the netting set that are not subject to a variation margin agreement or that are subject to a variation margin agreement under which the counterparty is not required to post variation margin form a single sub-netting set. The aggregated amount for this sub-netting set is calculated as if the netting set is not subject to a variation margin agreement. (2) All derivative contracts within the netting set that are subject to variation margin agreements in which the counterparty must post variation margin and that share the same value of the MPOR form a single sub-netting set. The aggregated amount for this sub-netting set is calculated as if the netting set is subject to a variation margin agreement, using the MPOR value shared by the derivative contracts within the netting set.

(d) * * * (10) * * * (i) With prior written approval of the Board, a Board-regulated institution may set EAD equal to a measure of counterparty credit risk exposure, such as peak EAD, that is more conservative than an alpha of 1.4 times the larger of EPEunstressed and EPEstressed for every counterparty whose EAD will be measured under the alternative measure of counterparty exposure. The Board-regulated institution must demonstrate the conservatism of the measure of counterparty credit risk exposure used for EAD. With respect to paragraph (d)(10)(i) of this section: (A) For material portfolios of new OTC derivative products, the Board-regulated institution may assume that the standardized approach for counterparty credit risk pursuant to paragraph (c) of this section meets the conservatism requirement of this section for a period not to exceed 180 days. (B) For immaterial portfolios of OTC derivative contracts, the Board-regulated institution generally may assume that the standardized approach for counterparty credit risk pursuant to paragraph (c) of this section meets the conservatism requirement of this section. ## * * * * *(e) * * * (6) * * * (viii) If a Board-regulated institution uses the standardized approach for counterparty credit risk pursuant to paragraph (c) of this section to calculate the EAD for any immaterial portfolios of OTC derivative contracts, the Board-regulated institution must use that EAD as a constant EE in the formula for the calculation of CVA with the maturity equal to the maximum of: (A) Half of the longest maturity of a transaction in the netting set; and (B) The notional weighted average maturity of all transactions in the netting set. |
