1. A credit institution, other than when acting as an originator, a sponsor or original lender, shall be exposed to the credit risk of a securitisation position in its trading book or non-trading book only if the originator, sponsor or original lender has explicitly disclosed to the credit institution that it will retain, on an ongoing basis, a material net economic interest which, in any event, shall not be less than 5 %.

For the purpose of this Article, "retention of net economic interest" means:

(a) retention of no less than 5 % of the nominal value of each of the tranches sold or transferred to the investors;

(b) in the case of securitisations of revolving exposures, retention of the originator’s interest of no less than 5 % of the nominal value of the securitised exposures;

(c) retention of randomly selected exposures, equivalent to no less than 5 % of the nominal amount of the securitised exposures, where such exposures would otherwise have been securitised in the securitisation, provided that the number of potentially securitised exposures is no less than 100 at origination; or
