WASHINGTON (AP) -- Barack Obama isn't president yet, but his must-do list just got longer. The newest addition to the lengthy list of tasks after taking office: helping oversee the overhaul of the world's financial regulatory system.

That is one of the assignments to the president-elect from current global leaders after their weekend summit, where they pledged action to avoid a repeat of the financial mess that has caused worldwide economic chaos.

"Obama has a tall order," said Morris Goldstein, a senior fellow at the Peterson Institute for International Economics who spent years working at the International Monetary Fund, the world's financial firefighter.

"He has a lot of things he has to do quickly in a number of areas and doesn't have a lot of time to think about them," Goldstein said in an interview Sunday.

That will put a lot of pressure on Obama. He did not participate in the emergency two-day summit that concluded Saturday, instead sending representatives to meet with leaders on the sidelines.

After taking the oath of office Jan. 20, Obama will have to figure out in short order how far his administration is willing to go in revamping oversight of financial companies and products, in the United States and abroad, and nailing down the crucial details.

"Obama has an incredible mountain to climb in the way of the economic and financial situation," said

TOKYO (AP) -- Japan's economy slid into a recession for the first time since 2001, the government said Monday, as companies sharply cut back on spending in the third quarter amid the unfolding global financial crisis.

Government officials and economists warned that the world's second-largest economy could contract further in coming months.

Japan's economy shrank at an annual pace of 0.4 percent in the July-September period after a declining an annualized 3.7 percent in the second quarter. That means Japan, along with the 15-nation euro-zone, is now technically in a recession, defined as two straight quarters of contraction.

"What we're starting to see is the extent of deterioration in external demand start to weigh more heavily on the Japanese economy," said Glen Maguire, chief Asia economist at Societe Generale. "And I think looking forward, there's every indication that dynamic is going to continue."

The result was worse than expected. Economists surveyed by Kyodo News agency had predicted gross domestic product would gain an annualized 0.1 percent.

Japan's Economy Minister Kaoru Yosano said following the data's release that "the economy is in a recessionary phase."

But the worst may be yet to come, especially with dramatic declines in demand from consumers overseas

NEW YORK (AP) -- Oil prices tumbled below $67 a barrel to 16-month lows Wednesday after the government reported big increases in U.S. fuel supplies -- more evidence that the economic downturn is drying up energy demand.

The Energy Information Administration said crude inventories jumped by 3.2 million barrels last week, above the 2.9 million barrel increase expected by analysts surveyed by energy research firm Platts. Gasoline inventories rose by 2.7 million barrels last week, and inventories of distillates, which include heating oil and diesel, rose by 2.2 million barrels.

Over the last four weeks, the EIA said, motor gasoline demand was down 4.3 percent from the same period last year. Distillate fuel demand was down 5.8 percent, and jet fuel demand was down 9.2 percent.

"The main theme here that's driving this market into new low ground is demand deterioration," said Jim Ritterbusch, president of energy consultancy Ritterbusch and Associates. "As we begin to see evidence that demand is leveling -- it doesn't have to increase, just level -- then we can start discussing a possible price bottom. But it appears premature at this point."

Light, sweet crude for December delivery fell $5.43 to settle at $66.75 on the New York Mercantile Exchange, after falling as low as $66.20. It was the lowest close for a front-month contract since June 13, 2007, when crude settled at $66.26.

The energy markets have also been weighed down by the weak stock market, as investors grow more pessimistic about how long it will take the economy to recover from the current global financial turmoil.

EW YORK (AP) -- How could a $24 billion loss possibly be good news? When it comes from Wachovia as an effort to primp itself for its acquisition by Wells Fargo.

Wachovia Corp.'s staggering loss for the third quarter resulted primarily because it wrote down the value of intangible assets by almost $19 billion and built up its loan loss reserves by $4.8 billion, moves that seemed to please its suitor.

"It was prudent for Wachovia to put these losses behind them," said Wells Fargo Chief Financial Officer Howard Atkins in a release. "The asset write-downs, reserve build, and other items are consistent with our acquisition assumptions."

The moves tidy up Wachovia's balance sheet so that it is more in line with that of the more conservative Wells Fargo, analysts said. At the same time, Wells Fargo can use the losses reported by Wachovia to shelter years of profits after it acquires the Charlotte, N.C.-based bank.

Late last month, the Internal Revenue Service issued a surprise ruling that boosts banks' ability to offset the losses from loans and other bad debts held by banks they acquire. The guidance allows banks to take larger tax write-offs against future profits and makes the bargain-basement $14 billion all-stock Wachovia deal all the more attractive for San Francisco-based Wells Fargo.

The ruling removes any limitation on how much a company can offset its income with the losses of an acquired company, said Walter Pagano, a partner at Eisner LLP and a former IRS revenue agent. Under the old ruling, companies could only write off a small portion of the losses, limiting how much of a tax

Apple Inc. said its profit jumped 26 percent in its fiscal fourth quarter as the newest iPhone outsold the market-leading BlackBerry from Research in Motion Ltd.

Despite the blockbuster performance, which sent Apple's shares soaring in after-hours trading, the company issued what it called "prudent" predictions for the current quarter, because of broader economic uncertainty.

For the three months ended Sept. 27, Apple's profit climbed to $1.14 billion, or $1.26 per share, from $904 million, or $1.01 per share in the same period last year.

Sales jumped 27 percent to $7.9 billion from $6.22 billion in the year-ago quarter.

Cupertino, Calif.-based Apple's profit topped Wall Street's expectations, but sales missed. Analysts had expected the company to sell $8 billion worth of Macintosh computers, iPods, iPhones and other gadgets, for a profit of $1.11 per share, according to a Thomson Reuters poll.

On a conference call with analysts, Chief Executive Steve Jobs addressed concerns that economic weakness will eat into Apple's business through the holidays and beyond.

Jobs said Apple's customers are more likely to put off buying a new computer than to defect to other brands of PCs with lower prices. Apple, which is sitting on about $25 billion in cash, could use the downturn to invest in research and development, he said.

"We may get buffeted around by the waves a little bit, but we'll be fine," Jobs said.

SAN FRANCISCO (AP) -- Yahoo Inc. will fire at least 1,500 workers to cope with a crumbling economy that dented its third-quarter profit and turned up the heat on the slumping Internet company's management as investors stew over a missed opportunity to sell to Microsoft Corp. for $47.5 billion.

The purge outlined Tuesday represents a 10 percent reduction in Yahoo's payroll of about 15,000 employees. It's the second time in nine months that Yahoo has resorted to mass layoffs in what so far has been an ineffectual effort to rebound from a financial funk that has left its stock price near a 5 1/2-year low.

Yahoo's housecleaning, to be completed by the end of the year, provides the latest example of how a credit crisis that has already rocked banks and retailers is starting to rattle Silicon Valley, the nation's high-tech heartland.

Online auctioneer eBay Inc. is jettisoning 1,600 jobs while an array of startups are letting go workers to squirrel away more cash as venture capitalists become more cautious with their money. Even Google Inc., a company renowned for its free-spending ways, is starting to cut corners.

"We are going into what is very clearly a recession mode," Blake Jorgensen, Yahoo's chief financial officer, said in a Tuesday interview.

Yahoo felt the squeeze in the third quarter as the Sunnyvale, Calif.-based company earned $54.3 million, or 4 cents per share. That was a plunge of 64 percent from $151.3 million, or 11 cents per share, at the

SAN FRANCISCO (AP) -- IBM Corp.'s third-quarter profit jumped nearly 20 percent, surpassing analyst estimates, as the technology company overcame slumping hardware sales and signed a healthy number of new services contracts.

Armonk, N.Y.-based IBM had released partial results for the July-September period last week to try to reassure investors who had been driving down the company's stock price. The move helped stop a steeper decline, but Wall Street was still waiting for word about how much new business IBM brought in during the period.

In a closely watched indicator, IBM signed $12.7 billion in new services contracts in the quarter, down 4 percent, which still showed it was able to lock in lots of new business despite the tough economic times. Short-term contract signings were up 13 percent to $6.1 billion.

IBM gets about half its revenue from annuity-like payments flowing from contracts it may have inked months or years ago for services like consulting or technology outsourcing.

Profit came in two cents per share ahead of analysts' recently revised estimates.

IBM earned $2.82 billion, or $2.05 per share, in the three months ended Sept. 30. That compares with net income of $2.36 billion, or $1.68 per share, in the year-ago period.

Analysts surveyed by Thomson Reuters were expecting $2.03 per share.

IBM continues to get better at wringing out more costs to improve its profit margins. Gross profit margin,

NEW YORK (AP) -- Citigroup Inc., suffering its fourth straight quarterly loss and forfeiting the title of largest U.S. bank by assets, is falling behind in the historic reshuffling of the U.S. banking system.
