The European Securities and Markets Authority (ESMA) has published three Opinions setting out sector-specific principles in the areas of investment firms, investment management and secondary markets, aimed at fostering consistency in authorisation, supervision and enforcement related to the relocation of entities, activities and functions from the United Kingdom.

The Commission de Surveillance du Secteur Financier (CSSF), has confirmed that it supports the efforts undertaken by ESMA to avoid regulatory arbitrage and the establishment of letterbox entities. The principles laid down by ESMA in those three Opinions are in line with the CSSF’s practice.
