Hiroto Saikawa¡¯s tone bordered on defiant on Sept. 8 when discussing his future as chief executive officer of Nissan Motor Co. He accepted responsibility for the Carlos Ghosn scandals and said he¡¯d resign after a successor was found, but he wasn¡¯t taking the fall for a burgeoning controversy over his pay.

That strategy blew up 24 hours later when the embattled carmaker¡¯s board pushed him out, citing his excess compensation. Saikawa¡¯s last day will be Monday, and the board is looking at a pool of about 10 candidates for the job, probably one of the most challenging in global auto-making.

The end of Saikawa¡¯s four-decade career came in a conference room at Nissan¡¯s Yokohama headquarters, where board members met for more than five hours on Sept. 9 ¡ª with some joining by video from overseas, according to people familiar with the matter. Nissan declined to comment on board discussions and declined to make Saikawa available for comment.
