The White House and the Treasury are deep into negotiations with General Motors and Chrysler over reorganization plans that could result in freeing up more than $14 billion in emergency loans to keep the companies afloat through the first quarter of 2009, according to industry executives and a senior administration official.

The Bush administration appears to want an agreement with the automakers before Dec. 25. It was unclear, however, when all of the particulars might be worked out, said the senior official, who spoke on the condition of anonymity because of the delicate nature of the negotiations.
