(23)To ensure the stability and continuity of credit protection, the early termination of an STS on-balance-sheet securitisation by the originator should only be possible in certain limited, well-defined circumstances. Although the originator should be entitled to close out the credit protection early upon the occurrence of certain specified regulatory events, those events should involve actual changes in legislation or taxation that could not have been reasonably anticipated at the time of entering into the transaction and that have a material adverse effect on the originator’s capital requirements or the economics of the transaction relative to the parties’ expectations at that time. STS on-balance-sheet securitisations should not feature complex call clauses for the originator, in particular very short-dated time calls with the aim of temporarily changing the representation of their capital position on a case-by-case basis.
