Article 234
Calculating risk-weighted exposure amounts and expected loss amounts in the event of partial protection and tranching
Where an institution transfers a part of the risk of a loan in one or more tranches, the rules set out in Chapter 5 shall apply. Institutions may consider materiality thresholds on payments below which no payment shall be made in the event of loss to be equivalent to retained first loss positions and to give rise to a tranched transfer of risk.
