Each class A share of a nominal value of DKK 10 entitles ten votes, and each class B share of a nominal value of DKK 10 entitles one vote, cf. article 11.b. Shareholders are entitled to vote, if they have obtained admission cards in due time and have caused their shares to be entered in the register of shareholders or have reported and submitted proof of their acquisition, cf. article 4.f. Shareholders who have acquired shares by transfer cannot exercise the voting rights attached to the shares in question without such shares having been registred in the register of shareholders or the shareholder having given notice of and evidenced the acquisition prior to this notice, cf. article 11.b.

However, according to the commencement provisions of the Companies Act, the proposals under item 7c. on the agenda can be adopted if just one shareholder votes in favour of the proposal.
