no responsibility for any other information that others may provide you. You should not assume that the information contained in this prospectus
supplement or the accompanying prospectus, as well as information Citigroup previously filed with the Securities and Exchange Commission and
incorporated by reference herein, is accurate as of any date other than the date of the relevant document. Citigroup is not, and the underwriters are not,
making an offer to sell the notes in any jurisdiction where the offer or sale is not permitted.
The Luxembourg Stock Exchange takes no responsibility for the contents of this document, makes no representation as to its accuracy or
completeness and expressly disclaims any liability whatsoever for any loss howsoever arising from or in reliance upon the whole or any part of the
contents of this prospectus supplement and the accompanying prospectus.
Each of the prospectus and prospectus supplement is an advertisement for the purposes of applicable measures implementing the European Council
Directive 2003/71/EC (such Directive, together with any applicable implementing measures in the relevant home Member State under such Directive, the
"Prospectus Directive"). A listing prospectus prepared pursuant to the Prospectus Directive will be published, which can be obtained from Registre de
Commerce et des Sociétés à Luxembourg so long as any of the notes are outstanding and listed on the Luxembourg Stock Exchange.

The distribution or possession of this prospectus and prospectus supplement in or from certain jurisdictions may be restricted by law. Persons into
whose possession this prospectus and prospectus supplement come are required by Citigroup and the underwriters to inform themselves about, and to
observe any such restrictions, and neither Citigroup nor any of the underwriters accepts any liability in relation thereto. See "Underwriting."
In connection with this issue, Citigroup Global Markets Inc. as stabilizing manager (or persons acting on behalf of the stabilizing manager) may
over-allot notes (provided that the aggregate principal amount of notes allotted does not exceed 105% of the aggregate principal amount of the notes) or
effect transactions with a view to supporting the market price of the notes at a higher level than that which might otherwise prevail. However, there is no
obligation on the stabilizing manager (or persons acting on its behalf) to undertake stabilization action. Any stabilization action may begin on or after the
date on which adequate public disclosure of the final terms of the notes is made and, if begun, may be discontinued at any time but must end no later than
the earlier of 30 days after the issuance of the notes and 60 days after the allotment of the notes.
This prospectus supplement and the accompanying prospectus are not an offer to sell these securities and are not soliciting an offer to buy these
securities in any jurisdiction where the offer or sale is not permitted or where the person making the offer or sale is not qualified to do so or to any person
to whom it is not permitted to make such offer or sale. See "Underwriting."
Prohibition of sales to EEA retail investors. The notes are not intended to be offered, sold or otherwise made available to and should not be
offered, sold or otherwise made available to any retail investor in the European Economic Area ("EEA"). For these purposes, a retail investor means a
person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU ("MiFID II"); (ii) a customer within the
meaning of Directive 2002/92/EC ("IMD"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID
II; or (iii) not a qualified investor as defined in the Prospectus Directive. Consequently no key information document required by Regulation (EU) No
1286/2014 (the "PRIIPs Regulation") for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared
and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs
Regulation.
MiFID II product governance / Professional investors and ECPs only target market. The target market for the notes is (i) eligible counterparties
and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the notes to eligible counterparties and professional
clients are appropriate.
This prospectus supplement and the accompanying prospectus are not an offer to sell these securities and are not soliciting an offer to buy these
securities in any jurisdiction where the offer or sale is not permitted or where the person making the offer or sale is not qualified to do so or to any person
to whom it is not permitted to make such offer or sale. See "Underwriting."
References in this prospectus supplement to "dollars", "$" and "U.S. $" are to United States dollars.
FORWARD-LOOKING STATEMENTS
Certain statements in this prospectus supplement, the accompanying prospectus and in other information incorporated by reference are "forward-
looking statements" within the meaning of the rules and regulations of the U.S. Securities and Exchange Commission. Generally, forward-looking
statements are not based on historical facts but instead represent only Citigroup's and its management's beliefs regarding future events. Such statements
may be identified by words such as believe, expect, anticipate, intend, estimate, may increase, may fluctuate, target, illustrate, and similar expressions, or
future or conditional verbs such as will, should, would and could.
Such statements are based on management's current expectations and are subject to risks, uncertainties and changes in circumstances. Actual results
and capital and other financial conditions may differ materially from those included in these statements due to a variety of factors, including without
limitation the precautionary statements included in the accompanying prospectus and the factors and uncertainties summarized under "Forward-Looking
Statements" in Citigroup's 2017 Annual Report on Form 10-K and the factors listed and described under "Risk Factors" in Citigroup's 2017 Annual
Report on Form 10-K. Precautionary statements included in such filing should be read in conjunction with this prospectus supplement and the
accompanying prospectus.

RISK FACTOR RELATED TO LIBOR DISCONTINUANCE
Interest during the Floating Rate Period will be determined using alternative methods if LIBOR is no longer available on the Reuters designated LIBOR
page and will be calculated using a substitute or successor base rate selected by Citigroup if LIBOR is discontinued.
If at any time during the Floating Rate Period, three-month LIBOR is no longer quoted on the Reuters designated LIBOR page described in
"Description of Debt Securities -- Interest Rate Determination -- Floating Rate Notes -- LIBOR Notes" in the accompanying prospectus, three-month
LIBOR will be determined using the alternative methods described in "Description of Debt Securities -- Interest Rate Determination -- Floating Rate
Notes -- LIBOR Notes" in the accompanying prospectus. Any of these alternative methods may result in interest payments on the notes during the Floating
Rate Period that are lower than or do not otherwise correlate over time with the interest payments that would have been made on the notes during the
Floating Rate Period if the Reuters designated LIBOR page had remained available. Any of the foregoing may have an adverse effect on the value of and
return on the notes.
https://www.sec.gov/Archives/edgar/data/831001/000119312518119647/d549500d424b2.htm[4/17/2018 2:32:49 PM]

424B2
Additionally, if during the Floating Rate Period, Citigroup (or an affiliate) determines that LIBOR has been discontinued or is permanently no longer
being published, Citigroup (or such affiliate) will use a substitute or successor base rate that it has determined, in its sole discretion after consulting with
any source it deems to be reasonable, to be the industry-accepted substitute or successor base rate, or, if there is no such industry-accepted substitute or
successor base rate, a substitute or successor base rate that is most comparable to three-month LIBOR. Citigroup (or such affiliate) also will determine, in
its sole discretion after consulting with any source it deems to be reasonable, any adjustments to the relevant methodology or definitions for calculating
such substitute or successor base rate, including any adjustment factor needed to make such substitute or successor base rate comparable to three-month
LIBOR, in a manner that is consistent with any industry-accepted practices for such substitute or successor base rate. The interests of Citigroup (or its
affiliate) in making the determinations described above may be adverse to your interests as a holder of the notes and may have an adverse effect on the
value of and return on the notes.

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 notes
will be limited initially to an aggregate principal amount of $2,000,000,000.
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
thereof. All the notes are unsecured obligations of Citigroup and will rank equally with all other unsecured senior indebtedness of Citigroup, 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 April 23, 2018 and will mature on April 23, 2029. The notes will bear interest (i) from the date of issuance of the notes
to, but excluding, April 23, 2028 (the "Fixed Rate Period") at a fixed rate equal to 4.075% per annum, payable semi-annually on the 23rd of each April and
October, commencing on October 23, 2018, and (ii) from, and including, April 23, 2028 (the "Floating Rate Period"), at an annual rate equal to three-
month LIBOR plus 1.192%, payable quarterly on July 23, 2028, October 23, 2028, January 23, 2029 and April 23, 2029, commencing on July 23, 2028.
https://www.sec.gov/Archives/edgar/data/831001/000119312518119647/d549500d424b2.htm[4/17/2018 2:32:49 PM]

424B2
Interest during the Fixed Rate Period 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. Interest during the Floating Rate Period will be determined
using the Reuters designated LIBOR page as described under "Description of Debt Securities -- Interest Rate Determination -- Floating Rate Notes --
LIBOR Notes" and "-- Payments of Principal and Interest" in the accompanying prospectus.
Notwithstanding the last two paragraphs in "Description of Debt Securities -- Interest Rate Determination -- Floating Rate Notes -- LIBOR Notes"
in the accompanying prospectus, if, on or prior to any interest determination date during the Floating Rate Period, Citigroup (or one of its affiliates)
determines that three-month LIBOR has been discontinued or is permanently no longer being published, Citigroup (or such affiliate) will use a substitute or
successor base rate that it has determined, in its sole discretion after consulting

S-4
Table of Contents
any source it deems to be reasonable, is (a) the industry-accepted substitute or successor base rate or (b) if there is no such industry-accepted substitute or
successor base rate, a substitute or successor base rate that is most comparable to three-month LIBOR.
Upon selection of a substitute or successor base rate, Citigroup (or such affiliate) may determine, in its sole discretion after consulting any source it
deems to be reasonable, the day count, the business day convention, the definition of business day, the interest determination date and any other relevant
methodology or definition for calculating such substitute or successor base rate, including any adjustment factor it determines is needed to make such
substitute or successor base rate comparable to three-month LIBOR, in a manner that is consistent with any industry-accepted practices for such substitute
or successor base rate.
The notes are redeemable at Citigroup's option, in whole at any time or in part from time to time, on or after October 23, 2018 and prior to April 23,
2028, 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 April 23, 2028, plus 0.200%. Citigroup may redeem the notes, at its option, (i) in whole, but not in part, on
April 23, 2028, or (ii) in whole at any time or in part from time to time, on or after January 23, 2029 at a redemption price equal to the sum of 100% of the
principal amount of the notes being redeemed 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.
Certain United States Federal Income Tax Considerations
The following disclosure supplements, and should be read together with, the section "United Stated Federal Income Tax Considerations--United
States Holders" in the accompanying prospectus.
United States Holders. United States holders that use an accrual method of accounting for tax purposes ("accrual method holders") generally are
required to include certain amounts in income no later than the time such amounts are reflected on certain financial statements (the "book/tax conformity
rule"). The application of the book/tax conformity rule thus may require the accrual of income earlier than would be the case under the general tax rules
described in the accompanying prospectus, although it is not clear to what types of income the book/tax conformity rule applies. This rule generally is
effective for tax years beginning after December 31, 2017 or, for notes issued with original issue discount, for tax years beginning after December 31,
2018. Accrual method holders should consult with their tax advisors regarding the potential applicability of the book/tax conformity rule to their particular
situation.
The book/tax conformity rule applies to OID in some cases, and therefore may require accrual method holders to include OID on OID notes in a
more accelerated manner than described in "United Stated Federal Income Tax Considerations--United States Holders--Original Issue Discount" in the
accompanying prospectus if they do so for financial accounting purposes. It is uncertain what adjustments, if any, should be made in later accrual periods
when taxable income exceeds income reflected on the United States holder's financial statements to reflect the accelerated accrual of income in earlier
periods. In addition, it is possible, although less likely, that accrual method holders may be required to include de minimis OID in gross income as the de
minimis OID accrues on their financial statements. The application of the book-tax conformity rule to OID and de minimis OID is uncertain, and accrual
method taxpayers should consult with their tax advisors on how the rule may apply to their investment in the notes.
Under the book/tax conformity rule, an accrual method holder that has made the election described in the second paragraph of "United Stated Federal
Income Tax Considerations--United States Holders--Market Discount" in the accompanying prospectus may be required to accrue market discount in a
more accelerated manner than described therein if the holder does so for financial accounting purposes. It is also possible, although less likely, that accrual
method holders that have not made the election described in such paragraph and that accrue market discount on a current basis on their financial statements
may be required to accrue market discount--including de minimis market discount--currently for U.S. federal income tax purposes. The application of the
book/tax conformity rule to notes with market discount is uncertain, and accrual method taxpayers should consult with their tax advisors on how the rule
may apply to their investment in the notes.

Accordingly, Industrial and Commercial Bank of China (Asia) Limited shall not be obligated to, and shall not, underwrite, subscribe, agree to purchase or
procure purchasers to purchase notes that may be offered or sold by other underwriters in the United States. Industrial and Commercial Bank of China
(Asia) Limited shall offer and sell the notes constituting part of their allotment solely outside the United States.
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 0.255% 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 0.150% 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 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 April 23, 2018, which is the fifth 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 two business days
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.
