Class by class disclosure; TD Art. 9(1)

Pursuant to Article 9(1) of the TD “[t]he voting rights shall be calculated on the basis of all the shares to which voting rights are attached even if the exercise thereof is suspended. Moreover this information shall also be given in respect of all the shares which are in the same class and to which voting rights are attached.” Is the provision concerning “class by class disclosure” an autonomous obligation? In other words, must a notification be made when the person reaches, exceeds or falls below the relevant thresh-olds in terms of a single class of shares (e.g. ordinary shares) calculated on the basis of all shares of that class issued, or it is only an additional disclosure requirement which arises only in the case in which an obligation of notification is met in terms of all the shares with voting rights held calculated on the basis of all the voting shares issued?
