GM: 'Substantial doubt' about survival

Automaker's annual report says it hopes to get $7.7 billion from the government to remain viable.

GM received $13.4 billion so far, and it has asked for up to $16.6 billion more. In addition, it is seeking $7.7 billion in loans to convert production from light trucks to more fuel efficient cars under an Energy Department loan program.

"The failure to obtain sufficient funding from the U.S. government or governments outside the United States may require us to shrink or terminate operations or seek reorganization for certain subsidiaries outside the United States," the filing said.

"If we fail to obtain sufficient funding for any reason, we would not be able to continue as a going concern and could potentially be forced to seek relief under the U.S. Bankruptcy Code," GM added.
