(24)Having regard to the principle of proportionality, in certain cases, the proposed acquirer should submit reduced information. In particular, where the proposed acquirer has been assessed for acquisition or increase in qualifying holdings by the same competent authority as that of the target entity within the previous 2 years, that proposed acquirer should be required to submit only the information that has changed since the previous assessment. Similarly, where the proposed acquirer is an authorised undertaking and subject to the prudential supervision of the same competent authority as that of the target entity, that proposed acquirer should be exempted from submitting certain information that is already in the possession of such competent authority. In both cases, the proposed acquirer should only submit information specific to the proposed acquisition together with a signed declaration certifying that the rest of the information that has not been submitted because already in possession of the competent authority is true, accurate and up-to-date.
