Article 28
Aggregation and allocation of trading orders
1.
Member States shall not permit management companies to carry out a UCITS order in aggregate with an order of another UCITS or another client or with an order on their own account, unless the following conditions are met:
(a)
it must be unlikely that the aggregation of orders will work overall to the disadvantage of any UCITS or clients whose order is to be aggregated;
(b)
an order allocation policy must be established and implemented, providing in sufficiently precise terms for the fair allocation of aggregated orders, including how the volume and price of orders determines allocations and the treatment of partial executions.
2.
Member States shall ensure that where a management company aggregates a UCITS order with one or more orders of other UCITS or clients and the aggregated order is partially executed, it allocates the related trades in accordance with its order allocation policy.
3.
4.
Member States shall require that, where a management company aggregates an order of a UCITS or another client with a transaction for own account and the aggregated order is partially executed, it allocates the related trades to the UCITS or other client in priority over those for own account.
However, if the management company is able to demonstrate to the UCITS or its other client on reasonable grounds that it would not have been able to carry out the order on such advantageous terms without aggregation, or at all, it may allocate the transaction for own account proportionally, in accordance with the policy as referred to in paragraph 1(b).
