(7)There are cases in which it is not possible for institutions to ascertain the relevant netting sets for a certain type of derivative in the CIU, since there is no information available on the counterparties or on whether the transactions are subject to a legally enforceable bilateral netting arrangement referred to in Article 272, point (4), of Regulation (EU) No 575/2013. In those cases, institutions should assume that neither netting effects nor counterparty diversification exist for that type of derivative. Therefore, institutions should assume that the CIU has entered into a single derivative with the maximum notional amount allowed by the mandate for that type of derivative.
