Scandal-battered Nissan won its shareholders’ approval Tuesday for a new system of committees to oversee governance and for keeping Chief Executive Hiroto Saikawa on its board.The Japanese automaker’s profits and dividends have tumbled amid a high-profile scandal involving its former chairman Carlos Ghosn. Some shareholders expressed worries about the future of the automaker. Saikawa and the other board members, including French alliance partner Renault Chairman Jean-Dominique Senard, bowed deeply at the meeting at a convention center in the port city of Yokohama, where Nissan Motor Corp. is based.“I’d like to offer my deepest apologies, representing the company, for how the misconduct has caused serious concern for our shareholders,” Saikawa said. Ghosn, who led Nissan for two decades, was arrested in November and is awaiting trial in Japan on charges of financial misconduct, including falsifying documents related to retirement compensation. He says he is innocent.The proposals to have committees overseeing compensation, board nominations and auditing required a majority of shareholders for a quorum and two-thirds of those voting for passage. Approval was shown by clapping among the more than 2,800 people present at the meeting. Most of the votes were submitted in advance.French automaker Renault, which owns 43% of Nissan, had earlier signaled it may abstain, saying it wanted more representation on the committees. To satisfy that request, the committees have Senard, who replaced Ghosn on the Nissan board, and Renault Chief Executive Thierry Bollore.
