(17)ESMA should develop updated draft regulatory technical standards in order to take into account the amendments introduced by this Regulation to Regulation (EU) No 909/2014. That would enable the Commission to make any necessary corrections or amendments with a view to clarifying the requirements set out in such existing regulatory technical standards. ESMA should also develop draft regulatory technical standards to specify the details of the pass-on mechanism, which types of transactions render the buy-in process unnecessary and how to take into account the specificities of retail investors when executing mandatory buy-ins.
