(5)Directive 2014/65/EU requires that any positions held by third parties on behalf of a person is to be included in the calculation of that person’s position limit and for position limits to be applied at both an entity level and at a group level. It is therefore necessary to aggregate positions at a group level. It is appropriate to only provide for aggregation at the group level if a parent undertaking can control the use of positions. Accordingly, parent undertakings should aggregate positions held by their subsidiaries with any positions that the parent undertaking holds directly, in addition to the subsidiaries aggregating their own positions. Such aggregation can lead to positions calculated at the level of the parent undertaking which are larger or, due to a netting of long and short positions held by different subsidiaries, lower than at individual subsidiary level. Positions should not be aggregated at the level of the parent undertaking if the positions are held by collective investment undertakings which hold those positions on behalf of their investors rather than on behalf of their parent undertakings in cases where the parent undertaking cannot control the use of those positions for its own benefit.
