Article 230
Calculating risk-weighted exposure amounts and expected loss amounts for an exposure with an eligible funded credit protection under the IRB Approach
1.
Under the IRB Approach, except for those exposures that fall under the scope of Article 220, institutions shall use the effective LGD (LGD*) as the LGD for the purposes of Chapter 3 to recognise funded credit protection eligible pursuant to this Chapter. Institutions shall calculate LGD* as follows:
where:
|
E |
= the exposure value before taking into account the effect of the funded credit protection; for an exposure secured by financial collateral eligible in accordance with this Chapter, that amount shall be calculated in accordance with Article 223(3); in the case of securities lent or posted, that amount shall be equal to the cash lent or securities lent or posted; for securities that are lent or posted, the exposure value shall be increased by applying the volatility adjustment (HE) in accordance with Articles 223 to 227; |
|
ES |
= the current value of the funded credit protection received after the application of the volatility adjustment applicable to that type of funded credit protection (HC) and the application of the volatility adjustment for currency mismatches (Hfx) between the exposure and the funded credit protection, in accordance with paragraphs 2 and 3; ES shall be capped at the following value: E·(1+HE); |
|
EU |
= E·(1+HE) – ES; |
|
LGDU |
= the applicable LGD for an unsecured exposure as set out in Article 161(1); |
|
LGDS |
= the applicable LGD to exposures secured by the type of eligible FCP used in the transaction, as specified in paragraph 2, Table 1. |
2.
Table 1 specifies the values of LGDS and Hc applicable in the formula set out in paragraph 1.
3.
Where an eligible funded credit protection is denominated in a different currency than that of the exposure, the volatility adjustment for currency mismatch (Hfx) shall be the same as the one that applies pursuant to Articles 224 to 227.
4.
As an alternative to the treatment set out in paragraphs 1 and 2 of this Article, and subject to Article 124(9), institutions may assign a 50 % risk weight to the part of the exposure that is, within the limits set out in Article 125(1), first subparagraph, and Article 126(1), first subparagraph, respectively, fully collateralised by residential property or commercial immovable property situated within the territory of a Member State where all of the conditions set out in Article 199(3) or (4) are met.
5.
To calculate risk-weighted exposure amounts and expected loss amounts for IRB exposures that fall within the scope of Article 220, institutions shall use E* in accordance with Article 220(4) and shall use LGD for unsecured exposures, as set out in Article 161(1), points (a), (aa) and (b).
