With respect to the calculation under Article 327 of the net position in each instrument, for positions in derivative instruments, where the derivative instrument can be treated as an equivalent position in its underlying instrument in accordance with Articles 328 to 330, the equivalent position in the underlying instrument may be netted off against other positions in the identical instrument of the institution (i.e. the underlying has the same ISIN as the other instrument of the institution).

For positions in derivative instruments, where the derivative instrument has multiple underlyings and can be exactly decomposed into equivalent positions in its underlying instruments, each of these equivalent position in the underlying instrument may be netted off against any other positions in identical instruments of the institution (i.e. identical means that the underlying has the same ISIN as the other instrument of the institution against which the derivative is netted).

Where the underlying is an index, a basket or a CIU referred to in Article 350(1) or (2), and the institution is aware of the underlying instruments of such index, basket or CIU, the equivalent position referred above (e.g. delta equivalent for options or combinations of long and short positions) may be further broken down into equivalent positions in the underlying constituents of the index, basket or CIU and netted against other positions in identical instruments of the institution.

Finally, in the specific case of positions hedged by credit derivatives, the offsetting rules in Articles 346 and 347 apply.

All the above holds regardless of whether a derivative is exchange-traded or over-the counter.
