Article 160 6.

For dilution risk of purchased corporate receivables, PD shall be set equal to the EL estimates of the institution for dilution risk. An institution that has received permission from the competent authority pursuant to Article 143 to use own estimates of LGD for corporate exposures that can decompose its EL estimates for dilution risk of purchased corporate receivables into PDs and LGDs in a manner that the competent authority considers to be reliable, may use the PD estimates that result from that decomposition. Institutions may recognise unfunded credit protection in the PD in accordance with Chapter 4.
