WASHINGTON -- President Bush on Friday announced $13.4 billion in emergency loans to prevent the collapse of General Motors and Chrysler, and another $4 billion available for the hobbled automakers in February with the entire bailout conditioned on the companies undertaking sweeping reorganizations to show that they can return to profitability, according to The New York Times.

The loans, as G.M. and Chrysler teeter on the brink of insolvency, essentially throws the companies a lifeline from the taxpayers that will keep them afloat until March 31. At that point, the new Obama administration will determine if the automakers are meeting the conditions of the loans and will continue to receive government aid or must repay the loans and face bankruptcy proceedings.

Mr. Bush made his announcement a week after Senate Republicans blocked legislation to aid the automakers that had been negotiated by the White House and Congressional Democrats, and the loan package announced by the president includes roughly the identical requirements in that bill, which had been approved by the House.
