(19)A number of Member States already require that a cover pool monitor perform specific tasks regarding the quality of eligible assets and ensures compliance with national coverage requirements. It is therefore important, in order to harmonise the treatment of covered bonds across the Union, that the tasks and responsibilities of the cover pool monitor, where one is required by the national framework, are clearly defined. The existence of a cover pool monitor does not obviate the responsibilities of national competent authorities as regards covered bond public supervision, particularly as regards compliance with the requirements laid down in the provisions of national law transposing this Directive.
