The report, from global outplacement consultancy Challenger, Gray & Christmas, mentioned that several prominent firms were among those announcing leadership changes, including Advanced Micro Devices (NYSE:AMD), Google (NASDAQ:GOOG) and eHarmony. January's total was 8% higher than the same month one year ago, when 89 CEO changes were reported by the consultancy. Of the turnovers, 31 were resignations and 25 CEOs stepped down, but will remain with their respective companies in some capacity. "We could see more changes like this as the economy continues to pull out of recession," said John Challenger, CEO of Challenger, Gray & Christmas.
