January's high layoff rate wasn't the only corporate shakeup that kicked off the new year. A report from outsourcing firm Challenger, Gray and Christmas showed the C-Suite was also shuffling chairs. The report said 123 CEOs left their posts in January, 28% more than exited in January 2010. Healthcare had the highest number of turnovers, with 25 CEO exits. The industry had the highest number of turnovers in all of 2011, with about 16 of its top executives leaving every month. The pharmaceutical industry ranked fifth, coming after the financial, government/non-profit and computer industries, with nine CEO departures, compared with four in January 2011. The top three reasons for leaving were resignation, retirement and stepping down.
