(10)As the rules laid down in this Regulation determine conditions for the application of the methodology set out in Delegated Regulation (EU) 2015/63 adopted pursuant to Article 103(7) of Directive 2014/59/EU, the differences between the calculation of the annual contributions by the Board for the institutions authorised in the participating Member States and the calculation of the annual contributions in the Member States which are not participating in the SRM should reflect only the specificities of a unified system in the participating Member States. Such specificities arise in particular from the fact that in the SRM there is a single target level for all participating Member States. The application, as a general rule, of the same methodology for the calculation of annual contributions in all Member States should preserve a level playing field among participating Member States and a strong internal market.
