Where there is a securitisation of revolving exposures subject to an early amortisation provision, the originator credit institution shall calculate, in accordance with Annex IX, an additional risk-weighted exposure amount in respect of the risk that the levels of credit risk to which it is exposed may increase following the operation of the early amortisation provision.

For those purposes, a ‘revolving exposure’ shall be an exposure whereby customers' outstanding balances are permitted to fluctuate based on their decisions to borrow and repay, up to an agreed limit, and an early amortisation provision shall be a contractual clause which requires, on the occurrence of defined events, investors' positions to be redeemed before the originally stated maturity of the securities issued.
