(3)Where a derivative contract is composed of a combination of derivative contracts, the competent authorities need to understand the characteristics of each of the derivative contracts concerned. Since competent authorities also need to be able to understand the overall context, it should also be apparent from the transaction report that the transaction is part of an overall strategy. Therefore, derivative contracts relating to a combination of derivative contracts should be reported in separate legs for each derivative contract with an internal identifier to provide a linkage between the legs.
