Car major inches closer to bankruptcy

General Motors Corp is in "intense" and "earnest" preparations for a possible bankruptcy filing, a source familiar with the company's plans said.

A plan to split the corporation into a "new" company made up of the most successful units, and an "old" one of its less-profitable units, is gaining momentum and is seen as the most sensible configuration, said another source familiar with the talks.

If the plan goes through, the new GM would be expected to assume some previous creditor debt from bankruptcy proceedings, such as secured debt, said the second source, adding that GM bondholders were likely to lose substantial value in bankruptcy.
