The U.S. government is moving to provide more short-term aid to General Motors Corp. (GM) to keep the auto giant afloat as it spends the next two months completing a new restructuring plan.

The Obama administration is working with GM officials to determine how much the company needs to survive in the short term, an administration official said Wednesday. No decisions have been made on the amount of any new loans or when they would be issued, said the official, who spoke on the condition of anonymity. The company has already received $13.4 billion in bailout funds.

On Monday, President Barack Obama set a 60-day deadline for GM to come up with a new restructuring plan to justify the company's overall request for up to $16.6 billion in new loans to get through the recession. But GM has said it needs some of that money immediately to avoid a collapse - including a short-term infusion of possibly $2.6 billion, its new chief executive said this week.

The Treasury has said it would provide "working capital" to carry GM to the new, June 1 deadline.

It is not clear how much the company will need or by when, but GM's newly installed CEO, Fritz Henderson, indicated this week that GM may need at least another infusion of $2.6 billion.

Henderson, speaking to reporters Tuesday, noted that recent cost-cutting measures allowed the company to withdraw a request for $2 billion in aid to get through March. He added that he hoped further cost cutting would allow the company to further delay requests for aid.

"At this point, frankly, we've been able to push off a lot of the draws," Henderson said, according to a transcript provided by a company spokesman. "We'll stay in touch [with the U.S. Treasury] in terms of whether or not we'll need the 2.6."

Henderson said that the company has been regularly submitting financial reports to the Treasury detailing its needs but that the administration hasn't been "explicit" about how much further short-term support it will provide.

"My anticipation is when they say they'll provide working capital for 60 days, they'll work with us to do what's necessary to get through this period and not a dollar more," Henderson said.

A Treasury official told reporters two weeks ago that GM has requested more aid to get through April.

GM spokesman Greg Martin said Wednesday the company has "deferred" to the task force on its needs and is still awaiting a determination.

"They know what we might need," Martin said.
