ZURICH, Switzerland (AP) -- UBS AG will write off a further $10 billion in losses from the U.S. subprime lending market, the Swiss bank said Monday, and raise billions in capital through share sales to Singapore and an unidentified investor in the Middle East.

UBS said it will post a loss for the fourth quarter and may now record a loss for the full year as well. That comes on top of the 4.2 billion francs written off in its third quarter, making 14.2 billion francs ($12.6 billion) in writedowns from the subprime crisis by UBS this year.

The Government of Singapore Investment Corp., a sovereign-wealth fund, is investing 11 billion Swiss francs ($9.75 billion), while an undisclosed strategic investor in the Middle East is contributing 2 billion francs ($1.77 billion).

As recently as the middle of November, UBS had predicted a profit for the fourth quarter despite ongoing speculation about its subprime holdings.
