(44)Appropriate and proportionate information requirements should be established which take account of the status of a client as either retail or professional. An objective of Directive 2004/39/EC is to ensure a proportionate balance between investor protection and the disclosure obligations which apply to investment firms. To this end, it is appropriate that less stringent specific information requirements be included in this Directive with respect to professional clients than apply to retail clients. Professional clients should, subject to limited exceptions, be able to identify for themselves the information that is necessary for them to make an informed decision, and to ask the investment firm to provide that information. Where such information requests are reasonable and proportionate investment firms should provide additional information.
