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

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 25, 2017 and will mature on April 24, 2048. The notes will bear interest (i) from
the date of issuance of the notes to, but excluding, April 24, 2047 (the "Fixed Rate Period") at a fixed rate equal to 4.281%
per annum, payable semi-annually on the 24th of each April and October, commencing on October 24, 2017, and (ii)
from, and including, April 24, 2047 (the "Floating Rate Period"), at an annual rate equal to three-month LIBOR plus
1.839%, payable quarterly on July 24, 2047, October 24, 2047, January 24, 2048 and April 24, 2048, commencing on
July 24, 2047. 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.
The notes are redeemable at Citigroup's option, in whole at any time or in part from time to time, on or after
October 24, 2017 and prior to April 24, 2047, 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;
S-3

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 24, 2047, plus
0.250%. Citigroup may redeem the notes, at its option, (i) in whole, but not in part, on April 24, 2047, or (ii) in
whole at any time or in part from time to time, on or after October 24, 2047 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

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 0.500% 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 0.250% 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
S-6

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 25, 2017,
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 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
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 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.
