Article 280c
Credit risk category add-on
For the purposes of paragraph 2, institutions shall establish the relevant credit reference entities of the netting set in accordance with the following:
there shall be one credit reference entity for each issuer of a reference debt instrument that underlies a single-name transaction allocated to the credit risk category; single-name transactions shall be assigned to the same credit reference entity only where the underlying reference debt instrument of those transactions is issued by the same issuer;
there shall be one credit reference entity for each group of reference debt instruments or single-name credit derivatives that underlie a multi-name transaction allocated to the credit risk category; multi-names transactions shall be assigned to the same credit reference entity only where the group of underlying reference debt instruments or single-name credit derivatives of those transactions have the same constituents.
For the purposes of Article 278, institution shall calculate the credit risk category add-on for a given netting set as follows:
where:

credit risk category add-on; |
j |
= |
the index that denotes all the credit risk hedging sets established in accordance with point (c) of Article 277a(1) and with Article 277a(2) for the netting set; and |
|
= |
the credit risk category add-on for hedging set j calculated in accordance with paragraph 3. |
Institutions shall calculate the credit risk category add-on for hedging set j as follows:
where:
|

the credit risk category add-on for hedging set j; |
єj |
= |
the hedging set supervisory factor coefficient of hedging set j determined in accordance with Article 280; |
k |
= |
the index that denotes the credit reference entities of the netting set established in accordance with paragraph 1; |
|
= |
the correlation factor of the credit reference entity k; where the credit reference entity k has been established in accordance with point (a) of paragraph 1,
|
AddOn(Entityk) |
= |
the add-on for the credit reference entity k determined in accordance with paragraph 4. |
Institutions shall calculate the add-on for the credit reference entity k as follows:
where:
|
= |
the effective notional amount of the credit reference entity k calculated as follows:
where:
|
Institutions shall calculate the supervisory factor applicable to the credit reference entity k as follows:
an institution using the approach referred to in Chapter 3 shall map the internal rating of the individual issuer to one of the external credit assessments;
for the credit reference entity k established in accordance with point (b) of paragraph 1:
