Article 429d
Additional provisions on the calculation of the exposure value of written credit derivatives
Institutions shall calculate the effective notional amount of written credit derivatives by adjusting the notional amount of those derivatives to reflect the true exposure of the contracts that are leveraged or otherwise enhanced by the structure of the transaction.
Institutions may fully or partly reduce the exposure value calculated in accordance with paragraph 2 by the effective notional amount of purchased credit derivatives, provided that all the following conditions are met:
the remaining maturity of the purchased credit derivative is equal to or greater than the remaining maturity of the written credit derivative;
the purchased credit derivative is otherwise subject to the same or more conservative material terms as those in the corresponding written credit derivative;
the purchased credit derivative is not purchased from a counterparty that would expose the institution to Specific Wrong-Way risk, as defined in point (b) of Article 291(1);
where the effective notional amount of the written credit derivative is reduced by any negative change in fair value incorporated in the institution's Tier 1 capital, the effective notional amount of the purchased credit derivative is reduced by any positive fair value change that has been incorporated in Tier 1 capital;
the purchased credit derivative is not included in a transaction that has been cleared by the institution on behalf of a client or that has been cleared by the institution in its role as a higher-level client in a multi-level client structure and for which the effective notional amount referenced by the corresponding written credit derivative is excluded from the total exposure measure in accordance with point (g) or (h) of the first subparagraph of Article 429a(1), as applicable.
For the purpose of calculating the potential future exposure in accordance with Article 429c(1), institutions may exclude from the netting set the portion of a written credit derivative which is not offset in accordance with the first subparagraph of this paragraph and for which the effective notional amount is included in the total exposure measure.
