Section 12.12 - Credit Exposure Arising from Derivative and Securities Financing Transactions(a) 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 state bank for purposes of determining the bank's lending limit pursuant to Finance Code, § 34.201, and this subchapter.(b) Derivative transactions.(1) Non-credit derivatives. Subject to paragraphs (2) - (4) of this subsection, a state bank shall calculate the credit exposure to a counterparty arising from a derivative transaction by one of the following methods. Subject to paragraphs (3) and (4) of this subsection, a bank shall use the same method for calculating counterparty credit exposure arising from all of its derivative transactions. (A) Model method. (i) Credit exposure. The credit exposure of a derivative transaction under the model method is equal to the sum of the current credit exposure of the derivative transaction and the potential future credit exposure of the derivative transaction.(ii) Calculation of current credit exposure. A bank 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, then the current credit exposure is zero.(iii) Calculation of potential future credit exposure. A bank shall calculate its potential future credit exposure by using an internal model that has been approved in writing for purposes of 12 C.F.R. § 324.132(d) (or 12 C.F.R. § 217.132(d) in the case of a bank that is a member of the Federal Reserve System), provided that the bank notifies the commissioner prior to its use for purposes of this section, or another model approved by the department based on the views of the bank's primary federal banking regulatory agency and any third party testing and evaluation reports submitted to the commissioner. Any substantive revisions to an internal model made after the bank has provided notice of its use, or after the commissioner has approved the use of an alternate model, must be approved by the commissioner before a bank may use the revised model for purposes of this section.(iv) Net credit exposure. A bank that calculates its credit exposure by using the model method pursuant to this subparagraph may net credit exposures of derivative transactions arising under the same qualifying master netting agreement.(B) Conversion factor matrix method. The credit exposure arising from a derivative transaction under the conversion factor matrix method is equal to and will remain fixed at the potential future credit exposure of the derivative transaction, which equals the product of the notional amount of the derivative transaction and a fixed multiplicative factor determined by reference to Table 1 of this section.

(C) Current exposure method. The credit exposure arising from a derivative transaction (other than a credit derivative transaction) under the current exposure method is calculated in the manner provided by 12 C.F.R. § 324.34(b)-(c) (or 12 C.F.R. § 217.34(b)-(c) in the case of a bank that is a member of the Federal Reserve System).(2) Credit derivatives. (A) Counterparty exposure. (i) General rule. Notwithstanding paragraph (1) of this subsection and subject to clause (ii) of this subparagraph, a state bank 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 § 12.2 of this title (relating to Definitions), shall calculate the counterparty credit exposure arising from credit derivatives entered by the bank by adding the net notional value of all protection purchased from the counterparty on each reference entity.(ii) Special rule for certain effective margining arrangements. A bank must add the effective margining arrangement threshold amount to the counterparty credit exposure arising from credit derivatives calculated under the model method. The effective margining arrangement 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 net credit exposure to the counterparty.(B) Reference entity exposure. A state bank shall calculate the credit exposure to a reference entity arising from credit derivatives entered into by the bank by adding the net notional value of all protection sold on the reference entity. A bank 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.(3) Special rule for central counterparties. In addition to amounts calculated under paragraphs (1) and (2) of this subsection, the measure of counterparty exposure to a central counterparty must also include the sum of the initial margin posted by the bank plus any contributions made by it to a guaranty fund at the time such contribution is made. However, this requirement does not apply to a bank that uses an internal model pursuant to paragraph (1)(A) of this subsection if such model reflects the initial margin and any contributions to a guaranty fund.(4) Mandatory or alternative use of method. The commissioner may in the exercise of discretion require or permit a state bank to use a specific method or methods set forth in this subsection to calculate the credit exposure arising from all derivative transactions, from any category of derivative transactions, or from a specific derivatives transaction if the commissioner in the exercise of discretion finds that such method is consistent with the safety and soundness of the bank.(c) Securities financing transactions.(1) In general. Except as provided by paragraph (2) of this subsection, a state bank shall calculate the credit exposure arising from a securities financing transaction by one of the following methods. A state bank shall use the same method for calculating credit exposure arising from all of its securities financing transactions. (A) Model method. A state bank may calculate the credit exposure of a securities financing transaction by using an internal model that has been approved in writing for purposes of 12 C.F.R. § 324.132(b) (or 12 C.F.R. § 217.132(b) in the case of a bank that is a member of the Federal Reserve System), provided that the bank notifies the commissioner prior to its use for purposes of this section, or another model approved by the department based on the views of the bank's primary federal banking regulatory agency and any third party testing and evaluation reports submitted to the commissioner. Any substantive revisions to an internal model made after the bank has provided notice of its use, or after the commissioner has approved the use of an alternate model, must be approved by the commissioner before a bank may use the revised model for purposes of this section.(B) Basic method. A state bank may calculate the credit exposure of a securities financing transaction as follows:(i) 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.(ii) Securities lending. (I) 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.(II) 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 by reference to 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.(iii) 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 by reference to Table 2 of this section, and the amount of cash transferred.(iv) Securities borrowing.(I) 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 by reference to Table 2 of this section, and the amount of cash transferred to the other party.(II) 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 by reference to 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.

(C) Basel collateral haircut method. A state bank may calculate the credit exposure of a securities financing transaction in the manner provided by 12 C.F.R. § 324.132(b)(2)(i) and (ii) (or 12 C.F.R. § 217.132(b)(2)(i) and (ii) in the case of a bank that is a member of the Federal Reserve System).(2) Mandatory or alternative use of method. The commissioner may in the exercise of discretion require or permit a state bank to use a specific method or methods set forth in this subsection to calculate the credit exposure arising from all securities financing transactions, from any category of securities financing transactions, or from a specific derivatives transaction if the commissioner finds in the exercise of discretion that such method is consistent with the safety and soundness of the bank.7 Tex.
