Den valgte fremgangsmåde skal sikre, at der harmoniseres i det omfang, det er nødvendigt for at sikre en gensidig anerkendelse af godkendelser og tilsynssystemer, således at det bliver muligt at give en godkendelse, der er gyldig overalt i EU, og at anvende hjemlandstilsyn.
The approach adopted is to ensure the essential harmonisation necessary and sufficient to secure the mutual recognition of authorisation and of prudential supervision systems, making possible the grant of a single authorisation valid throughout the European Union and the application of the home Member State supervision.
