(27)Investment firms should aim to identify and manage the conflicts of interest arising in relation to their various business lines and their group's activities under a comprehensive conflicts of interest policy. In particular, the disclosure of conflicts of interest by an investment firm should not exempt it from the obligation to maintain and operate the effective organisational and administrative arrangements required under Article 13(3) of Directive 2004/39/EC. While disclosure of specific conflicts of interest is required by Article 18(2) of Directive 2004/39/EC, an over-reliance on disclosure without adequate consideration as to how conflicts may appropriately be managed is not permitted.
