(3)In re-securitisation transactions credit risk transfer occurs at the level of the first securitisation of assets and at the second ‘repackaged’ level of the transaction. The two levels of the transaction, and the two corresponding instances of credit risk transfer, are independent with respect to the requirements set out in this Regulation. Retention of net economic interest and due diligence should be ensured at each level of the transaction by the institutions that become exposed to transferred credit risk at that particular level. Therefore if an institution becomes exposed only to the second ‘repackaged’ level of the transaction, the requirements relating to retention of net economic interest and due diligence only apply to that institution in relation to the second level of the transaction. Within the same re-securitisation transaction, those institutions who became exposed to the first level of securitisation of assets should comply with the retention and due diligence requirements in relation to the first level of securitisation in the transaction.
