For the second straight month, nervous employers got rid of jobs nationwide. In February, they sliced payrolls by 63,000, even deeper than the 22,000 cut in January, the Labor Department reported Friday.

The grim snapshot of the country's employment climate underscored the heavy toll the housing and credit debacles are taking on companies, jobseekers and the economy as a whole.

"It sounds like the recession bell is ringing for the U.S. economy, although it is still faint," said Stuart Hoffman, chief economist at PNC Financial Services Group.

AIG has been thrust to the forefront of the credit crisis gripping financial markets by contracts known as credit default swaps.

These swaps pledge to cover missed payments on $579 billion in debt. AIG's swap portfolio lost $11.12 billion in value during the fourth quarter because decaying credit quality means the insured debt is less likely to be repaid.

AIG also lost more than $3 billion in its investment portfolio because of "significant, rapid declines" in the value of mortgage debt.

AIG lost $5.29 billion, or $2.08 per share, in the fourth quarter, compared with profit of $3.44 billion, or $1.31 per share, in the fourth quarter of 2006.

For all of 2007, AIG earned $6.2 billion, or $2.39 per share, compared with $14.05 billion, or $5.36 per share, in 2006.

"AIG's results in 2007 were clearly unsatisfactory," AIG's chief executive, Martin J. Sullivan, said in a statement. "This was a challenging year in which the deterioration of both the U.S. residential mortgage and credit markets significantly affected several of our operations and investments."

Donn Vickrey, an analyst with Gradient Analytics, said AIG's management is under pressure to demonstrate it grasps the risks the company has taken.

The deterioration in the value of the swaps is more than double an estimate the company made just two weeks ago. At the end of the third quarter, AIG thought the portfolio of swaps had lost $352 million in value.

"They definitely seem to be right in the cross-hairs," Vickrey said. "They're insuring a lot of the risks that are rapidly becoming problematic."

AIG claims the losses on the portfolio swaps are only on paper because the debt the swaps protect is still stellar — just the market value of the contracts has fallen. As long as the insured debt does not go into default, the losses on the swaps will reverse over time, the company said.

The company's general insurance division posted a 22 percent decline in income to $2.02 billion. The division's mortgage insurance business, United Guaranty, posted a steep loss because flagging home prices have squashed the incentive and means for borrowers to repay home loans.

The life insurance division posted a 51 percent drop in profit, to $1.29 billion, because of bad investments.

January's sales increase followed a 0.4 percent decline in December and was contrary to Wall Street analysts' forecasts for a 0.2 percent decline. The surprise sales rise caused stock futures to jump on hopes it meant the United States had a better chance of skirting a recession.

Prices for U.S. debt securities fell while the dollar's value strengthened against other major currencies.

Excluding autos, January sales still rose 0.3 percent, reversing a 0.3 percent decline in December sales. Wall Street analysts were expecting a 0.2 percent gain in sales excluding autos.

"The data is clearly a surprise to the upside," said Omer Esiner, a market analyst with Ruesch International in Washington, D.C. "In the near term, it does ease some recession concerns."

Despite the higher headline number for sales, there were declines in many categories that implied consumer spending was being pinched. Furniture sales fell 0.5 percent in January, building material sales were down 1.7 percent and department store sales declined by 1.1 percent.

Many analysts think the slowing U.S. economy faces increasing risks of tumbling into recession and are closely watching for signs that consumers, who fuel 70 percent of national economic activity, will keep scaling back spending.

The U.S. Justice Department said on Friday it will not appeal the dismissal of its indictment of Norwegian shipping group Stolt-Nielsen in a price fixing case.

Earlier this month, a Pennsylvania court threw out a criminal indictment against the company and two of its executives.

Judge Bruce Kauffman of the U.S. District Court for the Eastern District of Pennsylvania, who tossed out the indictment, said Stolt-Nielsen had cooperated with the Justice Department to dismantle illegal collusion among three long-haul carriers in exchange for a promised amnesty for prosecution.
