DESCRIPTION OF NOTES
The following description of the particular terms of the notes supplements the description of the
general terms set forth in the accompanying prospectus. It is important for you to consider the information
contained in the accompanying prospectus and this prospectus supplement before making your decision to

General
The notes oÅered by this prospectus supplement are a series of senior debt securities issued under

Í50,000,000,000.
The notes will be issued only in fully registered form without coupons, in denominations of Í100,000

$17,204,560,030 of additional debt securities under the registration statement of which this prospectus
supplement and the accompanying prospectus form a part. Citigroup may, without notice to or consent of
the holders or beneÑcial owners of the notes, issue additional notes having the same ranking, interest rate,
maturity and other terms as the notes. Any such additional notes issued could be considered part of the
same series of notes under the indenture as the notes.

described below. See ""Ì Redemption for Tax Purposes.'' The redemption price for the notes will be 100%
of the principal amount thereof plus accrued interest to the date of the redemption. The notes are not
subject to any sinking fund.
The currency for payment for the notes is Yen. However, when interests in the notes are held through
DTC, all payments in respect of such DTC notes will be made in U.S. dollars, unless the holder of a
beneÑcial interest in the DTC notes elects to receive payment in Yen. See ""Currency Conversions and
Foreign Exchange Risks AÅecting Yen Notes Ì Currency Conversion''.
The notes will be issued on October 31, 2005. The notes will bear interest at a Ñxed rate per annum

S-7

If an interest payment date or the maturity date falls on a day that is not a Business Day, the
payment due on such interest payment date or maturity date will be postponed to the next succeeding
Business Day, and no further interest will accrue in respect of such postponement. For this purpose,
""Business Day'' means any day which is a day on which commercial banks settle payments and are open
for general business in New York City, London and Tokyo.
If a date for payment of interest or principal on the notes falls on a day that is not a business day in
the place of payment, such payment will be made on the next succeeding business day in such place of
payment as if made on the date the payment was due. No interest will accrue on any amounts payable for
the period from and after the due date for payment of such principal or interest.
A Ñscal agency agreement has been entered into in relation to the notes between Citigroup, Citibank,
N.A. London oÇce, as registrar, Ñscal agent and exchange agent, and the other paying agent named
therein. Payment of principal of and interest on the notes will be made through the oÇce of the Ñscal
agent in London. The terms ""registrar,'' ""Ñscal agent,'' ""exchange agent'' and ""paying agent'' shall include
any successors appointed from time to time in accordance with the provisions of the Ñscal agency
agreement, and any reference to an ""agent'' or ""agents'' shall mean any or all (as applicable) of such
persons.
The noteholders are bound by, and are deemed to have notice of, the provisions of the Ñscal agency
agreement. Copies of the Ñscal agency agreement are available for inspection during usual business hours
at the principal oÇce of the Ñscal agent. Copies of the Ñscal agency agreement will also be available for
inspection, free of charge, at the oÇce of Dexia Banque Internationale fia Luxembourg S.A.
Listing
Application will be made to list the notes on the regulated market of the Luxembourg Stock
Exchange.
The European Commission has adopted a Directive of the European Parliament and of the Council
(2004/109/EC), the ""Transparency Directive'') on the harmonization of transparency requirements
relating to Ñnancial information of issuers whose securities are admitted to trading on a regulated market
in the European Union, such as the Luxembourg Stock Exchange. If the Transparency Directive is
implemented in Luxembourg in a manner that would require Citigroup to publish its Ñnancial statements
according to accounting principles or standards that are materially diÅerent from U.S. generally accepted
accounting principles or that would otherwise impose requirements on Citigroup that it in good faith
determines are unduly burdensome, Citigroup may seek to de-list the notes. Citigroup will use its
reasonable best eÅorts to obtain an alternative admission to listing, trading and/or quotation for the notes
by another listing authority, exchange and/or system within or outside the European Union, as it may
decide. If such an alternative admission is not available to Citigroup or is, in Citigroup's opinion, unduly
burdensome, an alternative admission may not be obtained. Notice of any de-listing and/or alternative
admission will be given as described in ""Ì Notices'' below.
Book-Entry Notes
The information set out below in connection with The Depository Trust Company, the Euroclear
System and Clearstream International is subject to any change in or reinterpretation of the rules,
regulations and procedures of the clearing systems currently in eÅect. The information in this section
concerning the clearing systems has been obtained from sources that we believe to be reliable, but neither
we nor any underwriter takes any responsibility for the accuracy thereof.
Investors wishing to use the facilities of any of the clearing systems are advised to conÑrm the
applicability of the rules, regulations and procedures of the relevant clearing system. Neither Citigroup nor
any other party to the Ñscal agency agreement will have any responsibility or liability for any aspect of the
records relating to, or payments made on account of interests in the notes held through the facilities of,
S-8

any clearing system or for maintaining, supervising or reviewing any records relating to such beneÑcial
ownership interests.
General
Notes which are oÅered and sold outside the United States (the ""international notes'') will be
represented by beneÑcial interests in fully registered permanent global notes (the ""international global
notes'') without interest coupons attached, which will be registered in the name of Citivic Nominees
Limited, as nominee for, and shall be deposited on or about October 31, 2005 with Citibank, N.A. London
oÇce, as common depositary for, and in respect of interests held through, Euroclear Bank S.A./N.V., as
operator of the Euroclear System, and Clearstream.
Notes which are oÅered and sold in the United States (the ""DTC notes'' and, together with the
international notes, the ""notes'') will be represented by beneÑcial interests in fully registered permanent
global notes (the ""DTC global notes'' and together with the international global notes, the ""global notes'')
without interest coupons attached, which will be deposited on or about October 31, 2005 with Citibank,
N.A. London oÇce, as custodian for, and registered in the name of Cede & Co., as nominee for, The
Depository Trust Company.
Together, the notes represented by the global notes will equal the aggregate principal amount of the
notes outstanding at any time. The amount of notes represented by each of the DTC global notes and the
international global notes is evidenced by the register maintained for that purpose by the registrar.
BeneÑcial interests in the global notes will be shown on, and transfers thereof will be eÅected only
through, records maintained by DTC, Euroclear and Clearstream and their participants. Except as
described herein, individual registered certiÑcates will not be issued in exchange for beneÑcial interests in
the global notes.
A holder of international notes will receive all payments under the international notes in Yen. A
holder of DTC notes will receive all payments under the DTC notes in U.S. dollars, unless such holder
makes an election as described in this prospectus supplement under ""Currency Conversions and Foreign
Exchange Risks AÅecting Yen Notes Ì Currency Conversions'' for payment in Yen.
Subject to applicable law and the terms of the indenture, Citigroup, the registrar and any paying
agent will treat the persons in whose names the global notes are registered, initially Cede & Co. and
Citivic Nominees Limited, as owners of such notes for the purpose of receiving payments of principal and
interest (and additional amounts, if any) on the notes and for all other purposes whatsoever. Therefore,
none of Citigroup, the registrar or any paying agent has any direct responsibility or liability for the
payment of principal of or interest on the notes to owners of beneÑcial interests in the global notes. All
payments made by Citigroup to the registered holders of the global notes shall discharge the liability of
Citigroup under the notes to the extent of the sums so paid.
The Depository Trust Company
DTC is acting as securities depositary for the DTC notes. The DTC notes will be issued as fully
registered notes registered in the name of Cede & Co. DTC is:
, a limited-purpose trust company organized under the New York Banking Law;
, a ""banking organization'' under the New York Banking Law;
, a member of the Federal Reserve System;
, a ""clearing corporation'' under the New York Uniform Commercial Code; and
, a ""clearing agency'' registered under the provisions of Section 17A of the United States Securities
Exchange Act of 1934, as amended.
DTC holds securities that its direct participants deposit with DTC. DTC also facilitates the settlement
among direct participants of securities transactions, such as transfers and pledges, in deposited securities
S-9

through electronic computerized book-entry changes in direct participants' accounts, thereby eliminating
the need for physical movement of securities certiÑcates.
Direct participants of DTC include securities brokers and dealers (including underwriters), banks,
trust companies, clearing corporations, and certain other organizations. DTC is owned by a number of its
direct participants and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc., and
the National Association of Securities Dealers, Inc. Indirect participants of DTC, such as securities
brokers and dealers, banks and trust companies, can also access the DTC system if they maintain a
custodial relationship with a direct participant.
If you are not a direct participant or an indirect participant and you wish to purchase, sell or
otherwise transfer ownership of, or other interests in, notes, you must do so through a direct participant or
an indirect participant. DTC agrees with and represents to DTC participants that it will administer its
book-entry system in accordance with its rules and by-laws and requirements of law. The United States
Securities and Exchange Commission has on Ñle a set of the rules applicable to DTC and its direct
participants.
Purchases of notes under DTC's system must be made by or through direct participants, which will
receive a credit for the notes on DTC's records. The ownership interest of each beneÑcial owner is in turn
to be recorded on the records of direct participants and indirect participants. BeneÑcial owners will not
receive written conÑrmation from DTC of their purchase, but beneÑcial owners are expected to receive
written conÑrmations providing details of the transaction, as well as periodic statements of their holdings,
from the direct participants or indirect participants through which such beneÑcial owners entered into the
transaction. Transfers of ownership interests in the notes are to be accomplished by entries made on the
books of participants acting on behalf of beneÑcial owners. BeneÑcial owners will not receive certiÑcates
representing their ownership interests in notes, except in limited circumstances.
The DTC notes deposited with DTC are registered in the name of DTC's nominee, Cede & Co. The
deposit of notes with DTC and their registration in the name of Cede & Co. eÅect no change in beneÑcial
ownership. DTC has no knowledge of the actual beneÑcial owners of the notes. DTC's records reÖect only
the identity of the direct participants to whose accounts such notes are credited, which may or may not be
the beneÑcial owners. The participants will remain responsible for keeping account of their holdings on
behalf of their customers.
Conveyance of notices and other communications by DTC to direct participants, by direct participants
to indirect participants and by direct participants and indirect participants to beneÑcial owners will be
governed by arrangements among them, subject to any statutory or regulatory requirements as may be in
eÅect from time to time.
