Boards should reflect a diversity of knowledge, experience, and gender in order to pursue the social interests of a company. The Code recommends that female candidates should be nominated to cover vacancies of independent directors. Board members are collectively to exhibit diversity and breadth of qualifications, experience and background. Companies are to strive for equal gender distribution on the board. Nomination committees must issue a statement when the notice to the shareholders' meeting is issued, explaining its proposals with regard to the requirements concerning the composition of the board.
