For purchased corporate receivables in respect of which an institution is not able to estimate PDs or an institution's PD estimates do not meet the requirements set out in Section 6, the PDs for these exposures shall be determined in accordance with the following methods:
an institution that has received the permission of the competent authority to use own LGD estimates for corporate exposures pursuant to Article 143 and that can decompose its EL estimates for purchased corporate receivables into PDs and LGDs in a manner that the competent authority considers to be reliable, may use the PD estimate that results from this decomposition.
Institutions may take into account unfunded credit protection in the PD in accordance with the provisions of Chapter 4. For dilution risk, in addition to the protection providers referred to in Article 201(1)(g) the seller of the purchased receivables is eligible if the following conditions are met:
the corporate entity, in the case of institutions calculating risk-weighted exposure amounts and expected loss amounts under the IRB Approach, does not have a credit assessment by a recognised ECAI and is internally rated as having a PD equivalent to that associated with the credit assessments of ECAIs determined by EBA to be associated with credit quality step 3 or above under the rules for the risk weighting of exposures to corporates under Chapter 2.
An institution that has received the permission of the competent authority pursuant to Article 143 to use own LGD estimates for dilution risk of purchased corporate receivables, may recognise unfunded credit protection by adjusting PDs subject to Article 161(3).
