(7)To ensure that the relevant information is exchanged within a reasonable timeframe while avoiding situations where the competent authorities of a home Member State are obliged to forward any information about an investment firm, regardless of its nature and importance, to all competent authorities of host Member States, it is appropriate in some specific cases that only information that is relevant to a particular branch should be transmitted exclusively to the competent authorities in charge of supervising this branch. For similar efficiency and proportionality purposes, in a number of specific areas, only information regarding identified situations of non-compliance should be exchanged between competent authorities of home and host Member States, meaning that no information would have to be exchanged where the investment firm is in conformity with national and Union law.
