Embattled auto supplier Delphi's released the first half numbers and — who would have guessed it — they're awash in red ink. Yup, they're drowning in it — losing $2.6 billion during the first half of the year. But just like Delphi's baby-daddy, General Motors, the majority of those losses are associated with its attrition program. That'd be the more than 12,000 hourly UAW and IUEW workers who've taken the early-retirement plan. But that only accounts for $1.9 billion of the loss. Delphi's well-heeled, well-salaried and well-bonused execs still need to explain why the bankrupt company lost $700 million with revenue only up $100 million or so from the $13.9 billion it made in the first half of 2005.
