Dynegy's board has accepted a sweetened $603 million takeover bid by Blackstone Group LP but the deal still faces opposition from a prominent shareholder.

The private equity group on Tuesday increased its offer for the Houston power plant owner by 11 percent to $5 per share.

Shareholders vote on the deal later Wednesday and approval is far from certain. Financier Carl Icahn said Tuesday he would oppose the increased offer, saying it still undervalues the company. Icahn owns a nearly 13 percent stake in Dynegy.

Icahn also said the takeover agreement discouraged other bidders from submitting competing offers. Dynegy has agreed to pay Blackstone a $16.3 million breakup fee if the deal isn't approved.

The shareholder vote is expected later Wednesday in Houston.

Record company Warner Music Group Corp. said Wednesday that its fiscal 2010 fourth-quarter loss widened on lower revenue, reflecting the continued shift from CD sales to digital music.

The company lost $46 million, or 31 cents per share, compared with a loss of $18 million, or 12 cents per share, during the same period a year prior. Revenue fell 13 percent to $752 million from $867 million. The fourth quarter ended Sept. 30.

Analysts surveyed by Thomson Reuters expected a loss of 13 cents per share on $731.7 million in revenue.

"The company's revenue results continue to reflect the transition from physical to digital in the recorded music industry where increases in digital revenue have not yet fully offset the declines in physical revenue," the company said in a statement.

Revenue from recorded music fell 13.3 percent to $619.9 million during the quarter, with the U.S., Japan, and most of Europe the weakest markets. But digital revenue from the sector rose 7 percent to $183 million.

Just a day before its historic return to the New York Stock Exchange, General Motors confirmed Wednesday that it would expand its initial public offering of common shares by 31 percent.

The company, responding to superheated investor demand for its stock, said it will raise the size of its IPO to 478 million common shares from the previously announced 365 million. Most of the common stock will be sold by the U.S. government, which is trying to unload what is now a 61 percent stake in the country's largest automaker.

The IPO, scheduled for Thursday, will cap a stunning resurrection for an automaker that nearly ran out of cash in 2008 and lost more than $80 billion in the four years leading up to its bankruptcy filing last year.

"This is, in my knowledge, one of the most remarkable turnarounds in corporate history," said Anant Sundaram, a finance professor at Dartmouth College's Tuck School of Business.

The most beloved capitalist in the world, Warren Buffett, has written another charming, thoughtful article in the New York Times.

And this one will make a lot of Americans furious.

Buffett's article is a "thank-you note" to our government, thanking them for the bailouts and emergency actions that Buffett says saved America from economic Armageddon two years ago.  Although people will always criticize the details, Buffett says, they can't criticize the outcome, which was remarkable:

"Uncle Sam, you delivered. People will second-guess your specific decisions; you can always count on that. But just as there is a fog of war, there is a fog of panic — and, overall, your actions were remarkably effective."

Buffett makes a compelling case that, if the government had done nothing in the financial crisis, the financial system and economy might have collapsed, at least temporarily.  And given that the system did NOT collapse, the government's intervention certainly was commendable.

But, as many people have already pointed out, no one benefited more from the bailouts than Warren Buffett, so it's no surprise that he's grateful.  Most bailout critics, furthermore, don't suggest that the government should have sat around and done nothing--they argue that the government's intervention should have been more fair and effective, particularly with respect to Wall Street.

Mortgage applications fell sharply last week as mortgage rates pushed higher.

The volume of mortgage loan applications decreased 14.4% on a seasonally adjusted basis in the week ending Nov. 12, the Mortgage Bankers Association said early Wednesday.

Refinancing applications decreased 16.5% from the previous week to the lowest level observed since July. New-home purchase loan applications decreased 5% week-over-week, the first decrease after three consecutive weekly increases.

"Rates increased sharply last week due to stronger economic data and lingering uncertainty regarding the structure and impact of the Fed's QE2 program," said Michael Fratantoni, MBA's Vice President of Research and Economics. "Mortgage applications, particularly for refinances, dropped in response."
