(8)Additional legal certainty is also necessary with regard to the categorisation, as transferable securities, of financial instruments which are linked to the performance of other assets, including assets which are not referred to by Directive 85/611/EEC itself, or which are backed by such assets. It should be made clear that if the linkage to the underlying or to another component of the instrument amounts to an element which has to be considered as an embedded derivative, the financial instrument falls in the subcategory of transferable securities embedding a derivative element. This has the consequence that the criteria for derivatives under Directive 85/611/EEC have to be applied in respect of that element.
