In January, shareholders led by Choi introduced a cumulative voting system--which allows more flexibility in how votes are cast for selecting board members--and a 19-member cap on the company board, in order to fend off the MBK-Young Poong alliance, which had sought to add 14 new members to the then 12-member board. Korea Zinc's management under Choi also created a complex circular shareholding ownership structure to limit the voting rights of the MBK-Young Poong alliance. The alliance later sought a court injunction to nullify the series of moves; the Seoul court on Friday ruled for the cumulative voting system but against the company's limit on the board size and the voting rights of the alliance. Meanwhile, Young Poong's shares were 8.9% higher Monday after its announcement that it would cancel all the treasury shares it owns by March.
