(22)For some categories of issuers the competent authority should be entitled to require adapted information going beyond the information items included in the schedules and building blocks because of the particular nature of the activities carried out by those issuers. A precise and restrictive list of issuers for which adapted information may be required is necessary. The adapted information requirements for each category of issuers included in this list should be appropriate and proportionate to the type of business involved. The Committee of European Securities Regulators could actively try to reach convergence on these information requirements within the Community. Inclusion of new categories in the list should be restricted to those cases where this can be duly justified.
