1. Hedges shall be ‘ eligible hedges ’ for the purposes of the calculation of own funds requirements for CVA risk in accordance with Articles 383 and 384 only where they are used for the purpose of mitigating CVA risk and managed as such, and are one of the following:
(a) single-name credit default swaps or other equivalent hedging instruments referencing the counterparty directly;
(b) index credit default swaps, provided that the basis between any individual counterparty spread and the spreads of index credit default swap hedges is reflected, to the satisfaction of the competent authority, in the value-at-risk and the stressed value-at-risk.
The requirement in point (b) that the basis between any individual counterparty spread and the spreads of index credit default swap hedges is reflected in the value-at-risk and the stressed value-at-risk shall also apply to cases where a proxy is used for the spread of a counterparty.
For all counterparties for which a proxy is used, an institution shall use reasonable basis time series out of a representative group of similar names for which a spread is available.
If the basis between any individual counterparty spread and the spreads of index credit default swap hedges is not reflected to the satisfaction of the competent authority, then an institution shall reflect only 50 % of the notional amount of index hedges in the value-at-risk and the stressed value-at-risk.
Over-hedging of the exposures with single name credit default swaps under the method laid out in Article 383 is not allowed.
2. An institution shall not reflect other types of counterparty risk hedges in the calculation of the own funds requirements for CVA risk. In particular, tranched or nth-to-default credit default swaps and credit linked notes are not eligible hedges for the purposes the calculation of the own funds requirements for CVA risk.
3. Eligible hedges that are included in the calculation of the own funds requirements for CVA risk shall not be included in the calculation of the own funds requirements for specific risk as set out in Title IV or treated as credit risk mitigation other than for the counterparty credit risk of the same portfolio of transaction.]
