Article 270d 3.

Where the exposures underlying a securitisation benefit from full or partial eligible credit protection in accordance with Chapter 4, and the effect of such protection has been reflected in the credit assessment of a securitisation position by a nominated ECAI, the institution shall use the risk weight associated with that credit assessment. Where the credit protection referred to in this paragraph is not eligible under Chapter 4, the credit assessment shall not be recognised and the securitisation position shall be treated as unrated.
