On November 4, 2007, Citigroup Inc. issued a press release announcing significant declines since September 30, 2007 in the fair value of the approximately $55 billion in U.S. sub-prime related direct exposures in its Securities and Banking (S&B) business. Citi estimates that, at the present time, the reduction in revenues attributable to these declines ranges from approximately $8 billion to $11 billion (representing a decline of approximately $5 billion to $7 billion in net income on an after-tax basis).

These declines in the fair value of Citi’s sub-prime related direct exposures followed a series of rating agency downgrades of sub-prime U.S. mortgage related assets and other market developments, which occurred after the end of the third quarter. The impact on Citi’s financial results for the fourth quarter from changes in the fair value of these exposures will depend on future market developments and could differ materially from the range above.

Citi also announced that, while significant uncertainty continues to prevail in financial markets, it expects, taking into account maintaining its current dividend level, that its capital ratios will return within the range of targeted levels by the end of the second quarter of 2008. Accordingly, Citi has no plans to reduce its current dividend level.

A copy of the press release is being filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference in its entirety.
