Scope. This section sets forth the rules for calculating the credit exposure arising from a derivative transaction or a securities financing transaction entered into by a national bank or savings association for purposes of determining the bank's or savings association's lending limit pursuant to 12 U.S.C. 84 or 12 U.S.C. 1464(u), as applicable, and this part.

Derivative transactions—(1) Non-credit derivatives. Subject to paragraphs (b)(2), (b)(3) and (b)(4) of this section, a national bank or savings association shall calculate the credit exposure to a counterparty arising from a derivative transaction by one of the following methods. Subject to paragraph (b)(4) of this section, a national bank or savings association shall use the same method for calculating counterparty credit exposure arising from all of its derivative transactions.

Model Method—(A) Credit exposure. The credit exposure of a derivative transaction under the Internal Model Method shall equal the sum of the current credit exposure of the derivative transaction and the potential future credit exposure of the derivative transaction.

Calculation of current credit exposure. A bank or savings association shall determine its current credit exposure by the mark-to-market value of the derivative contract. If the mark-to-market value is positive, then the current credit exposure equals that mark-to-market value. If the mark to market value is zero or negative, than the current credit exposure is zero.

Calculation of potential future credit exposure. (1) A bank or savings association shall calculate its potential future credit exposure by using either:

An internal model the use of which has been approved in writing for purposes of 12 CFR 3.132(d) or 324.132(d), as appropriate, provided that the bank or savings association provides prior written notice to the appropriate Federal banking agency of its use for purposes of this section; or

Any other appropriate model the use of which has been approved in writing for purposes of this section by the appropriate Federal banking agency.

Any substantive revisions to a model made after the bank or savings association has provided notice of the use of the model to the appropriate Federal banking agency pursuant to paragraph (b)(1)(i)(C)(1)(i) of this section or after the appropriate Federal banking agency has approved the use of the model pursuant to paragraph (b)(1)(i)(C)(1)(ii) of this section must be approved by the agency before a bank or savings association may use the revised model for purposes of this part.

Net credit exposure. A bank or savings association that calculates its credit exposure by using the Internal Model Method pursuant to this paragraph (b)(1)(i) may net credit exposures of derivative transactions arising under the same qualifying master netting agreement.

Conversion Factor Matrix Method. The credit exposure arising from a derivative transaction under the Conversion Factor Matrix Method shall equal and remain fixed at the potential future credit exposure of the derivative transaction which shall equal the product of the notional amount of the derivative transaction and a fixed multiplicative factor determined by reference to Table 1 of this section.

Current Exposure Method. The credit exposure arising from a derivative transaction (other than a credit derivative transaction) under the Current Exposure Method shall be calculated pursuant to 12 CFR 3.132(c)(5), (6), and (7) or 324.132(c)(5), (6), and (7), as appropriate.

Credit Derivatives—(i) Counterparty exposure—(A) In general. Notwithstanding paragraph (b)(1) of this section and subject to paragraph (b)(2)(i)(B) of this section, a national bank or savings association that uses the Conversion Factor Matrix Method or the Current Exposure Method, or that uses the Model Method without entering an effective margining arrangement as defined in § 32.2(l), shall calculate the counterparty credit exposure arising from credit derivatives entered by the bank or savings association by adding the net notional value of all protection purchased from the counterparty on each reference entity.

Special rule for certain effective margining arrangements. A bank or savings association must add the EMA threshold amount to the counterparty credit exposure arising from credit derivatives calculated under the Model Method. The EMA threshold is the amount under an effective margining arrangement with respect to which the counterparty is not required to post variation margin to fully collateralize the amount of the bank's or savings association's net credit exposure to the counterparty.

Reference entity exposure. A national bank or savings association shall calculate the credit exposure to a reference entity arising from credit derivatives entered into by the bank or savings association by adding the net notional value of all protection sold on the reference entity. A bank or savings association may reduce its exposure to a reference entity by the amount of any eligible credit derivative purchased on that reference entity from an eligible protection provider.

Special rule for central counterparties. (i) In addition to amounts calculated under § 32.9(b)(1) and (2), the measure of counterparty exposure to a central counterparty shall also include the sum of the initial margin posted by the bank or savings association, plus any contributions made by it to a guaranty fund at the time such contribution is made.

Paragraph (b)(3)(i) of this section does not apply to a national bank or saving association that uses an internal model pursuant to paragraph (b)(1)(i) of this section if such model reflects the initial margin and any contributions to a guaranty fund.

Mandatory or alternative method. The appropriate Federal banking agency may in its discretion require or permit a national bank or savings association to use a specific method or methods set forth in paragraph (b)(1) of this section to calculate the credit exposure arising from all derivative transactions or any specific, or category of, derivative transactions if it finds, in its discretion, that such method is consistent with the safety and soundness of the bank or savings association.

Securities financing transactions—(1) In general. Except as provided by paragraph (c)(2) of this section, a national bank or savings association shall calculate the credit exposure arising from a securities financing transaction by one of the following methods. A national bank or savings association shall use the same method for calculating credit exposure arising from all of its securities financing transactions.

Model Method. (A) A national bank or savings association may calculate the credit exposure of a securities financing transaction by using either:

An internal model the use of which has been approved in writing by the appropriate Federal banking agency for purposes of 12 CFR 3.132(b) or 324.132(b), as appropriate, provided the bank or savings association provides prior written notice to the appropriate Federal banking agency of its use for purposes of this section; or

Any other appropriate model the use of which has been approved in writing for purposes of this section by the appropriate Federal banking agency.

Any substantive revisions to a model made after the bank or savings association has provided notice of the use of the model to the appropriate Federal banking agency pursuant to paragraph (c)(1)(i)(A)(1) of this section or after the appropriate Federal banking agency has approved the use of the model pursuant to paragraph (c)(1)(i)(A)(2) of this section must be approved by the agency before a bank or savings association may use the revised model for purposes of part 32.

Basic Method. A national bank or savings association may calculate the credit exposure of a securities financing transaction as follows:

Repurchase agreement. The credit exposure arising from a repurchase agreement shall equal and remain fixed at the market value at execution of the transaction of the securities transferred to the other party less cash received.

Securities lending— (1) Cash collateral transactions. The credit exposure arising from a securities lending transaction where the collateral is cash shall equal and remain fixed at the market value at execution of the transaction of securities transferred less cash received.

Non-cash collateral transactions. The credit exposure arising from a securities lending transaction where the collateral is other securities shall equal and remain fixed as the product of the higher of the two haircuts associated with the two securities, as determined in Table 2 of this section, and the higher of the two par values of the securities. Where more than one security is provided as collateral, the applicable haircut is the higher of the haircut associated with the security lent and the notional-weighted average of the haircuts associated with the securities provided as collateral.

Reverse repurchase agreements. The credit exposure arising from a reverse repurchase agreement shall equal and remain fixed as the product of the haircut associated with the collateral received, as determined in Table 2 of this section, and the amount of cash transferred.

Securities borrowing—(1) Cash collateral transactions. The credit exposure arising from a securities borrowed transaction where the collateral is cash shall equal and remain fixed as the product of the haircut on the collateral received, as determined in Table 2 of this section, and the amount of cash transferred to the other party.

Non-cash collateral transactions. The credit exposure arising from a securities borrowed transaction where the collateral is other securities shall equal and remain fixed as the product of the higher of the two haircuts associated with the two securities, as determined in Table 2 of this section, and the higher of the two par values of the securities. Where more than one security is provided as collateral, the applicable haircut is the higher of the haircut associated with the security borrowed and the notional-weighted average of the haircuts associated with the securities provided as collateral.

Basel Collateral Haircut Method. A national bank or savings association may calculate the credit exposure of a securities financing transaction pursuant to 12 CFR 3.132(b)(2)(i) and (ii) or 324.132(b)(2)(i) and (ii), as appropriate.

Mandatory or alternative method. The appropriate Federal banking agency may in its discretion require or permit a national bank or savings association to use a specific method or methods set forth in paragraph (c)(1) of this section to calculate the credit exposure arising from all securities financing transactions or any specific, or category of, securities financing transactions if the appropriate Federal banking agency finds, in its discretion, that such method is consistent with the safety and soundness of the bank or savings association.
