Item 5. Other Events.

Attached hereto as Exhibit 99.01 and incorporated by reference herein is the
Historical Annual Supplement of Citigroup Inc. and subsidiaries ("Citigroup").
Following the November 30, 2000 acquisition of Associates First Capital
Corporation ("Associates"), which was accounted for as a pooling of interests,
Citigroup presented the results of Associates as a separate operating segment.
In connection with the 2001 integration of Associates' businesses into existing
Citigroup businesses, Citigroup changed its operating segments presentation to
include the various Associates businesses within the other existing operating
segments of Citigroup. As a result, all relevant disclosures contained in the
Historical Annual Supplement of Citigroup have been restated to reflect this new
segment presentation for all periods presented.
