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 invest in the notes. If any specific 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.
The notes offered by this prospectus supplement are a new series of senior debt securities issued under Citigroup's senior debt indenture. The

The notes will be issued only in fully registered form without coupons, in denominations of $1,000 and integral multiples of $1,000 in excess

whether currently existing or hereinafter created.
Citigroup may, without notice to or consent of the holders or beneficial 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 October 27, 2017 and will mature on October 27, 2022. The notes will bear interest at a fixed rate of 2.700% per
annum. Interest on the notes will be paid semi-annually on the 27th day of each April and October, commencing April 27, 2018. Interest will be
calculated and paid as described under "Description of Debt Securities -- Interest Rate Determination -- Fixed Rate Notes" and "-- Payments of
Principal and Interest" in the accompanying prospectus.
The notes are redeemable at Citigroup's option, in whole at any time or in part from time to time, on or after April 27, 2018 and prior to
September 27, 2022, at a redemption price equal to the sum of (i) 100% of the principal amount of the notes being redeemed plus accrued and
unpaid interest thereon to, but excluding, the date of redemption; and (ii) the Make-Whole Amount (as defined on page 14 of the accompanying
prospectus), if any, with respect to such notes. The Reinvestment Rate (as defined on page 14 of the accompanying prospectus) will equal the
Treasury Yield (as defined on page 14 of the accompanying prospectus) calculated to September 27, 2022, plus 0.150%. Citigroup may redeem the
notes, at its option, in whole, but not in part, on or after September 27, 2022 at a redemption price equal to the sum of 100% of the principal
amount of the notes plus accrued and unpaid interest thereon to, but excluding, the date of redemption. In addition, Citigroup may redeem the notes
prior to maturity if changes involving United States taxation occur which could require Citigroup to pay additional amounts, as described under
"Description of Debt Securities -- Payment of Additional Amounts" and "-- Redemption for Tax Purposes" in the accompanying prospectus.

To the extent any underwriter that is not a U.S. registered broker-dealer intends to effect any offers or sales of any notes in the United States,
it will do so through one or more U.S. registered broker-dealers in accordance with the applicable U.S. securities laws and regulations.
The underwriting agreement provides that the obligations of the underwriters to pay for and accept delivery of the notes is 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 offer part of the notes directly to the public at the public offering price set forth on the cover page of this
prospectus supplement and to certain dealers at the public offering price less a concession not in excess of 0.195% of the principal amount of the
notes. The underwriters may allow, and such dealers may reallow, a concession to certain other dealers not in excess of 0.115% of the principal
amount of the notes.
After the public offering, the public offering price and the concessions to dealers may be changed by the underwriters.
The underwriters are offering 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 misstatements and omissions.
In connection with the offering, the underwriters may purchase and sell notes in the open market. Purchases and sales in the open market
may include short sales, purchases to cover short positions and stabilizing purchases.

· Short sales involve secondary market sales by the underwriters of a greater number of notes than they are required to purchase in the

offering.

· Stabilizing transactions involve bids to purchase the notes so long as the stabilizing bids do not exceed a specified maximum.

· Covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short

positions.
Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own account, may have
the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than it would
otherwise be in the absence of such transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise.
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.

We estimate that the total expenses of this offering 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 -- Listing" in the accompanying prospectus. Citigroup has been advised by the underwriters that it presently intends 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 affiliates may engage in transactions (which may include commercial banking transactions) with, and perform
services for, Citigroup or one or more of its affiliates in the ordinary course of business for which they may receive customary fees and
reimbursement of expenses.
Conflicts of Interest. Citigroup Global Markets Inc., the sole book-running manager for this offering, is a subsidiary of Citigroup.
Accordingly, the offering of the notes will conform with the requirements addressing

S-5
Table of Contents
conflicts of interest when distributing the securities of an affiliate set forth in Rule 5121 of the Financial Industry Regulatory Authority. Client
accounts over which Citigroup Global Markets Inc. or any affiliate have investment discretion are not permitted to purchase the notes, either
directly or indirectly, without the specific written approval of the accountholder.
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 October 27, 2017, which is the fourth 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 two
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 business day will be required, by virtue of the fact that the notes initially will not settle in T+2, 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 offered globally for sale in the United States, Europe, Asia and elsewhere where it is lawful to make such offers.
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 offer, sell or deliver any of the notes, directly or indirectly, or distribute this prospectus
supplement or the accompanying prospectus or any other offering material relating to the notes, in or from any jurisdiction, except when to the best
knowledge and belief of the underwriters it is permitted under applicable laws and regulations. In so doing, the underwriters will not impose any
obligations on Citigroup, except as set forth in the underwriting agreement.

Beginning in the first quarter of 2017, the remaining businesses and portfolios of assets in Citi Holdings will be reported as part of
Corporate/Other and Citi Holdings will cease to be a separately reported business segment. Its businesses conduct their activities across the
North America, Latin America, Asia and Europe, Middle East and Africa regions. Citigroup's principal subsidiaries are Citibank, N.A.,
Citigroup Global Markets Inc. and Grupo Financiero Banamex, S.A. de C.V., each of which is a wholly owned, indirect subsidiary of
