(20)In order to allow UCITS and their management companies to adapt to the new requirements on the method and manner to provide information to unit-holders in the cases referred to in Articles 7 and 29, Member States should be granted a longer period for the transposition of those requirements into their national legal systems. This is particularly important in those cases where the UCITS or their management companies are unable for legal or practical reasons to inform the unit-holders directly. UCITS with dematerialised bearer shares should be able to prepare all arrangements necessary to ensure that unit-holders receive the information in the cases specified in Articles 8 and 32. UCITS with materialised bearer shares should be able to convert them into registered shares or dematerialised bearer shares, if they want to be able to merge, convert into a feeder UCITS or change the master UCITS.
