(30)Differences regarding the efficiency, methods and timing of the checking of the information given in a prospectus not only make it more difficult for undertakings to raise capital or to obtain admission to trading on a regulated market in more than one Member State but also hinder the acquisition by investors established in one Member State of securities offered by an issuer established in another Member State or admitted to trading in another Member State. These differences should be eliminated by harmonising the rules and regulations in order to achieve an adequate degree of equivalence of the safeguards required in each Member State to ensure the provision of information which is sufficient and as objective as possible for actual or potential securities holders.
