Citigroup could write down as much as $24 billion due to subprime and credit-related losses, CNBC has learned. In addition, the company could lay off as many as 20,000 workers as part of a comprehensive plan to slash costs and raise capital.
The plans will be unveiled Tuesday, when it reports fourth-quarter earnings. At the same time, Citigroup could also announce that it is cutting its dividend payment.
Citibank also intends to raise as much as $15 billion from various foreign and domestic entities including Saudi Arabian Prince Alwaleed bin Talal, Citigroup's largest individual shareholder, as America's biggest bank grapples with heavy mortgage market losses.
