John Hammergren, the chairman, president, and CEO of drug distributor and health care services company McKesson, may have the largest pension for an individual on record, at a reported $159 million. The Wall Street Journal reported on Hammergren's pension Tuesday, citing company filings made last week. From The Journal: "Compensation consultants say it's by far the largest pension on file for a current executive of a public company, and almost certainly the largest ever in corporate America. It's also more than double the value of the 54-year-old Mr. Hammergren's pension six years ago."
