Details are emerging about how General Motors Corp.’s U.S. pension funds went from a $20-billion surplus at the end of 2007 to a $12.4-billion deficit 12 months later. Newly released numbers show that the funds, which help support more than 650,000 Americans, were tapped for billions of dollars over the past year for employee buyout programs, benefit increases and as part of the UAW’s retiree health care trust deal.
