(46)Taking into consideration the principles set out in the Commission’s Communication on reinforcing sanctioning regimes in the financial services sector and legal acts of the Union adopted as a follow-up to that Communication, Member States should lay down rules on penalties applicable to infringements of this Regulation. Member States should enforce those penalties in a manner that does not reduce the effectiveness of those rules. Those penalties should be effective, proportionate and dissuasive. They should be based on guidelines adopted by ESMA to promote convergence and cross-sector consistency of penalty regimes in the financial sector. Member States should ensure that the penalties imposed are publicly disclosed, where appropriate, and that assessment reports on the effectiveness of existing rules are published at regular intervals.
