[ESMA 70-872942901-36 Commodity derivatives Q&A, Q&A 3.11]

The various commodity derivative underlyings within the scope of the C(10) category shall be treated consistently across all provisions concerning commodity derivatives in the MiFID II/MiFIR framework. Therefore, all those commodity derivative contracts with underlyings that are subject to the position limit regime as specified in Q&A 1277 should also be counting towards the ancillary activity test calculations. Other contracts within the C(10) scope should not be counted.
