The general obligation to act solely in the interests of unit-holders and, in particular, the objective of increasing cost efficiencies, never justify a UCITS undertaking measures which may hinder the competent authorities from exercising effectively their supervisory functions.

Whereas the procedures for notifying the supervisory authority are designed to ensure disclosure of the purposes and main features of any processing operation for the purpose of verification that the operation is in accordance with the national measures taken under this Directive;

Processing of data relating to offences, criminal convictions or security measures may be carried out only if authorised by the Treaties establishing the European Communities or other legal instruments adopted on the basis thereof or, if necessary, by the European Data Protection Supervisor, subject to appropriate specific safeguards.

Moreover, when the customs office where release was granted is in the immediate vicinity of the slaughterhouse, the customs authorities, instead of using seals, may take appropriate supervisory measures to ensure that the horses are transferred directly to the slaughterhouse and are taken into the charge of the authority referred to in Article 308 (1).

Cooperation shall include the ability to serve the legal documents necessary to enforce measures taken by the competent authorities in connection with bids, as well as such other assistance as may reasonably be requested by the supervisory authorities concerned for the purpose of investigating any actual or alleged breaches of the rules made or introduced pursuant to this Directive.

Member States shall take the measures necessary to ensure that operators and suppliers of means of distance communication put an end to practices that have been declared to be contrary to this Directive, on the basis of a judicial decision, an administrative decision or a decision issued by a supervisory authority notified to them, where those operators or suppliers are in a position to do so.

For the sole purpose of applying the provisions of this Directive to reorganisation measures and winding-up proceedings concerning branches situated in the Community of an insurance undertaking whose head office is located in a third country the home Member State should be defined as the Member State in which the branch is located and the supervisory authorities and competent authorities as the authorities of that Member State.

If, despite the measures thus taken by the Member State of establishment, or because such measures prove inadequate or are lacking in the Member State in question, the undertaking persists in violating the legal rules in force in the Member State of provision of services, the latter Member State may, after informing the supervisory authorities of the Member State of establishment, take appropriate measures to prevent further irregularities, including, in so far as it is strictly necessary, the prevention of the further conclusion of insurance contracts by that undertaking by way of provision of services within its territory.

Cooperation shall also comprise measures to develop training for supervisory staff holding positions of responsibility in the regional and subregional integration processes.
