Item 5.           Other Information

         Grupo Financiero Banamex-Accival ("Banacci"), Mexico's top financial
institution, and Citigroup, the preeminent global financial services company,
announced today that they have reached an agreement through which Banacci, and
all its direct and indirect subsidiaries, will integrate with Citigroup's global
operations. Banacci shareholders will receive $6.25 billion in cash and
126,877,791 Citigroup shares which, based on a closing price of $49.26 on May
11th, have a value of $6.25 billion - for a total transaction value of $12.5
billion.

         The transaction grants equal treatment to all Banacci shareholders, and
the tender offer is for 100% of Banacci shares. Shareholders representing at
least 51% of Banacci's shares have agreed to tender their shares prior to
the tender offer. Citigroup will apply to have its shares listed on the Mexican
Stock Exchange. If approved, Citigroup will be the first international company
to be so listed.

         Under the terms of the transaction, Banacci and Citigroup's operations
in Mexico will be integrated, and will conduct business under the "Banamex"
brand name.

         The transaction, which has been unanimously approved by the Boards of
Directors of both companies, is subject to a number of regulatory approvals and
is expected to close in the fourth quarter.

         A joint press release announcing the transaction was issued on May 17,
