5.   Where a payment institution provides any of the payment services as referred to in points (1) to (7) of Annex I and, at the same time, is engaged in other business activities, the competent authorities may require the establishment of a separate entity for the payment services business, where the non-payment services activities of the payment institution impair or are likely to impair either the financial soundness of the payment institution or the ability of the competent authorities to monitor the payment institution’s compliance with all obligations laid down by this Directive.
