1.When determining the indirect exposure value to a client arising from derivative contracts written on debt, equity or credit default swap indices or collective investment undertaking, or with multi-underlying reference names, institutions shall look through to all the individual underlying instruments and calculate the indirect exposure values as the variation in the price of the derivative contract in the case of default of each of the underlying reference names. Institutions shall assign each indirect exposure value either to an identified client, a separate client or the unknown client, as laid down in Article 6(1) and (2) of Delegated Regulation (EU) No 1187/2014.
