Reuters reports that Merrill Lynch (NYSE: MER) is taking an enormous $5.7 billion write-down on losses from mortgage-backed securities (MBSs) and plans to raise $8.5 billion.

The biggest shocker was, as Reuters reports, that Merrill signed a contract with Singapore's Temasek, a sovereign wealth fund, that requires Merrill to pay $2.5 billion under terms of a previous stock sale to Temasek, along with $2.4 billion in required dividends to preferred shareholders. That's because under its previous deal, Merrill had agreed that if it sold shares at too low a price in the future, it would reimburse investors. Temasek has agreed to purchase $3.4 billion -- or 28% of the new offering. In other words, Merrill is paying an extremely high price for its capital.

The second shocker was how much of a write-down Merrill is taking on its portfolio of collateralized debt obligations (CDOs). Private equity fund Lone Star is paying 22 cents on the dollar, or $6.7 billion for CDOs with a stated book value of $30.6 billion. At that rate, the holders of $2 trillion worth of CDOs outstanding earlier this year would need to take a $1.56 trillion haircut if they sold all the CDOs. And I don't think they have nearly enough capital to be able to afford that.

Analyst summaries provided by TheFlyOnTheWall.com (subscription required).

Since the resignation of the company's CEO, Sovereign Bancorp (NYSE:SOV) has been the subject of buyout rumors. In fact, there has been heavy trading in the company's stock options. A possible suitor is Banco Santander Central Hispano, which already owns about 24.9% of Sovereign.

Of course, there has been lots of consolidation in the banking sector, a trend that should continue for some time. Still, why sell out now? Perhaps it would make more sense to fix the company and then sell it?

Interestingly enough, this is the view of an analyst from UBS, Matthew O'Connor. Actually, he thinks the company is already fully valued.
