DESCRIPTION OF SUBORDINATED 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
invest in the notes. If any speciÑc information regarding the notes in this prospectus supplement is
inconsistent with the more general terms of the notes described in the prospectus, you should rely on the
information contained in this prospectus supplement.
General
The notes oÅered by this prospectus supplement are a series of subordinated debt securities issued
under Citigroup's subordinated debt indenture. The notes will initially be limited to an aggregate principal
amount of $1,500,000,000.
S-4


The notes will be issued only in fully registered form without coupons, in denominations of $100,000
and whole multiples of $1,000 in excess thereof. All the notes are unsecured obligations of Citigroup and
will rank equally with all other unsecured and subordinated indebtedness of Citigroup, whether currently
existing or hereafter created, other than subordinated indebtedness that is designated as junior to the notes.
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.
The notes will be issued on August 25, 2006. The notes will bear interest at a Ñxed rate of 6.125% per
annum. Interest accrued on the notes will be payable semi-annually on the 25th day of each February and
August, beginning February 26, 2007. All payments of interest on the notes will be made to the persons in
whose names the notes are registered at the close of business on the February 15 or August 15 preceding
the interest payment date. Interest will be calculated and paid as described in ""Description of Debt
Securities Ì Interest Rate Determination Ì Fixed Rate Notes'' and ""Ì Payments of Principal and
Interest'' in the accompanying prospectus.
The subordinated notes will rank subordinate and junior in right of payment to Citigroup's senior
indebtedness, as described in ""Description of Debt Securities'' in the accompanying prospectus. On a
consolidated basis, the aggregate principal amount of senior indebtedness of Citigroup outstanding as of
June 30, 2006 was approximately $281.7 billion. This senior indebtedness consisted of approximately
$209.1 billion of long-term debt, approximately $33.1 billion of commercial paper and approximately
$39.5 billion of other short-term borrowings.

The underwriting agreement provides that the obligations of the underwriters to pay for and accept
delivery of the notes are subject to the approval of legal matters by their counsel and to other conditions.
The underwriters are committed to take and pay for all of the notes if any are taken.
The underwriters propose to oÅer part of the notes directly to the public at the public oÅering price
set forth on the cover page of this prospectus supplement and to certain dealers at the public oÅering price
less a concession not in excess of 0.500% of the principal amount of the notes. The underwriters may
S-5


allow, and such dealers may reallow, a concession to certain other dealers not in excess of 0.250% of the
principal amount of the notes.
After the public oÅering, the public oÅering prices and the concessions to dealers may be changed by
the underwriters.
The underwriters are oÅering the notes subject to prior sale and their acceptance of the notes from
Citigroup. The underwriters may reject any order in whole or in part.
Citigroup has agreed to indemnify the underwriters against liabilities relating to material misstate-
ments and omissions.
In accordance with Regulation M of the United States Securities Exchange Act of 1934, the
underwriters may over-allot or eÅect transactions that stabilize or cover, each of which is described below.
, Over-allotment involves sales in excess of the oÅering size, which creates a short position for the
underwriters.
, Stabilizing transactions involve bids to purchase the notes so long as the stabilizing bids do not
exceed a speciÑed maximum.
, Covering transactions involve purchases of the notes in the open market after the distribution has
been completed in order to cover short positions.
These transactions may cause the price of the notes to be higher than it would otherwise be in the
absence of such transactions. The underwriters are not required to engage in any of these activities and
may end any of these activities at any time. The underwriters may also impose a penalty bid. Penalty bids
permit an underwriter to reclaim a selling concession from a syndicate member when that underwriter, in
covering syndicate short positions or making stabilizing purchases, purchases notes originally sold by that
syndicate member.
We estimate that the total expenses of this oÅering will be $175,000.
The notes are a new series of securities with no established trading market. Citigroup will apply for
listing and trading of the notes on the regulated market of the Luxembourg Stock Exchange but we are
not required to maintain this listing. See ""Description of Debt Securities Ì Listing'' in the accompanying
prospectus. Citigroup has been advised by the underwriters that they presently intend to make a market in
the notes, as permitted by applicable laws and regulations. The underwriters are not obligated, however, to
make a market in the notes and may discontinue any market making at any time at their sole discretion.
Accordingly, Citigroup can make no assurance as to the liquidity of, or trading markets for, the notes.
The underwriters and their aÇliates may engage in transactions (which may include commercial
banking transactions) with, and perform services for, Citigroup or one or more of its aÇliates in the
ordinary course of business.
Citigroup Global Markets Inc., the lead manager for this oÅering, is a subsidiary of Citigroup.
Accordingly, the oÅering of the notes will conform with the requirements set forth in Rule 2720 of the
Conduct Rules of the NASD.
This prospectus supplement, together with the accompanying prospectus, may also be used by
Citigroup's broker-dealer subsidiaries or other subsidiaries or affiliates of Citigroup in connection with offers
and sales of the notes in market-making transactions at negotiated prices related to prevailing market prices
at the time of sale. Any of these subsidiaries may act as principal or agent in such transactions.
We expect that delivery of the notes will be made against payment therefor on or about August 25,
2006, which is the sixth business day after the date hereof. Under Rule 15c6-1 of the Securities Exchange
Act, trades in the secondary market generally are required to settle in three business days, unless the
parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on
the date hereof or the next following business day will be required, by virtue of the fact that the notes
initially will not settle in T°3, to specify an alternative settlement cycle at the time of any such trade to
prevent a failed settlement and should consult their own advisor.
The notes are being oÅered globally for sale in the United States, Europe, Asia and elsewhere where
it is lawful to make such oÅers.
S-6


Purchasers of the notes may be required to pay stamp taxes and other charges in accordance with the
laws and practices of the country of purchase in addition to the issue price set forth on the cover page of
this document.
The underwriters have agreed that they will not oÅer, sell or deliver any of the notes, directly or
indirectly, or distribute this prospectus supplement or the accompanying prospectus or any other oÅering
