(4)The Commission should be empowered to adopt the measures necessary for the implementation of Directive 2004/109/EC in order to clarify the technical aspects of some of the definitions provided under that Directive, notably the maximum length of the usual short settlement cycle, the calendar of trading days, the circumstances under which a person should have learnt of the acquisition or disposal of voting rights, the conditions of independence to be respected by market makers and management companies; take account of technical developments in financial markets; clarify the nature of the auditor’s review, to define the minimum content of the condensed set of solo financial statements; elaborate further the procedures for the notification and disclosure of major holdings as well as the procedures for filing regulated information with the competent authority of the issuer’s home Member State; and define minimum standards for the dissemination of regulated information and for the setting up of storage mechanisms. Since those measures are of general scope and are designed to amend non-essential elements of Directive 2004/109/EC, inter alia, by supplementing it with new non-essential elements, they must be adopted in accordance with the regulatory procedure with scrutiny provided for in Article 5a of Decision 1999/468/EC.
