Eligible unfunded credit protection and unfunded credit protection providers shall be limited to those which are eligible in accordance with Chapter 4 and recognition of credit risk mitigation shall be subject to compliance with the relevant requirements as laid down under Chapter 4.
Institutions which are allowed to apply the IRB Approach to a direct exposure to the protection provider may assess eligibility in accordance with the first subparagraph based on the equivalence of the PD for the protection provider to the PD associated with the credit quality steps referred to in Article 136.
By way of derogation from paragraph 2, SSPEs shall be eligible protection providers where all of the following conditions are met:
the SSPE owns assets that qualify as eligible financial collateral in accordance with Chapter 4;
all the requirements for the recognition of financial collateral set out in Chapter 4 are met.
Where a securitisation position benefits from full credit protection or a partial credit protection on a pro-rata basis, the following requirements shall apply:
In all cases not covered by paragraph 6, the following requirements shall apply:
the institution providing credit protection shall treat the portion of the position benefiting from credit protection as a securitisation position and shall calculate risk-weighted exposure amounts as if it held that position directly in accordance with Subsection 3, subject to paragraphs 8, 9 and 10;
the institution buying credit protection shall calculate risk-weighted exposure amounts for the protected portion of the position referred to in point (a) in accordance with Chapter 4. The institution shall treat the portion of the securitisation position not benefiting from credit protection as a separate securitisation position and shall calculate risk-weighted exposure amounts in accordance with Subsection 3, subject to paragraphs 8, 9 and 10.
Institutions using the Securitisation External Ratings Based Approach (SEC-ERBA) under Subsection 3 for the original securitisation position shall calculate risk-weighted exposure amounts for the positions derived in accordance with paragraph 7 as follows:
where the derived position has the higher seniority, it shall be assigned the risk weight of the original securitisation position;
where the derived position has the lower seniority, it may be assigned an inferred rating in accordance with Article 263(7). In that case, thickness input T shall only be computed on the basis of the derived position. Where a rating may not be inferred, the institution shall apply the higher of the risk weight resulting from either:
applying the SEC-SA in accordance with paragraph 8 and Subsection 3; or
the risk weight of the original securitisation position under the SEC-ERBA.
