1. For the covered portion of the exposure value (E), based on the adjusted value of the credit protection G A , the PD for the purposes of Section 4 of Chapter 3 may be the PD of the protection provider, or a PD between that of the borrower and that of the guarantor where a full substitution is deemed not to be warranted. In the case of subordinated exposures and non-subordinated unfunded protection, the LGD to be applied by institutions for the purposes of Section 4 of Chapter 3 may be that associated with senior claims.
2. For any uncovered portion of the exposure value (E) the PD shall be that of the borrower and the LGD shall be that of the underlying exposure.
3. For the purposes of this Article, G A is the value of G* as calculated under Article 233(3) further adjusted for any maturity mismatch as laid down in Section 5. E is the exposure value determined in accordance with Section 5 of Chapter 3. For this purpose, institutions shall calculate the exposure value of the items listed in Article 166(8) to (10) by using a conversion factor or percentage of 100 % rather than the conversion factors or percentages indicated in those paragraphs.]
