Today, the Luxembourg Parliament enacted the law (the “New Market Abuse Law”) implementing Directive 2014/57/EU of the European Parliament and of the Council of 16 April 2014 on criminal sanctions for market abuse (market abuse directive), also known as the “Market Abuse Criminal Sanctions Directive” (“Directive 2014/57/EU”) and Commission Implementing Directive (EU) 2015/2392 of 17 December 2015 on Regulation (EU) No 596/2014 of the European Parliament and of the Council as regards reporting to competent authorities of actual or potential infringements of that Regulation (“Directive (EU) 2015/2392”).
