DESCRIPTION OF SUBORDINATED NOTES
The following description of the particular terms of the subordinated 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 subordinated notes. If any specific information regarding the subordinated notes in this
prospectus supplement is inconsistent with the more general terms of the subordinated notes described in the prospectus, you should rely on the
information contained in this prospectus supplement.
The subordinated notes offered by this prospectus supplement are a new series of subordinated debt securities issued under Citigroup's
subordinated debt indenture. The notes will be limited initially to an aggregate principal amount of $2,500,000,000.
The subordinated 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 subordinated notes are unsecured obligations of Citigroup and will rank equally with all other unsecured and
subordinated indebtedness of Citigroup, whether currently existing or hereinafter created, other than subordinated indebtedness that is designated
as junior to the subordinated notes.
Citigroup may, without notice to or consent of the holders or beneficial owners of the subordinated notes, issue additional subordinated notes
having the same ranking, interest rate, maturity and other terms as the subordinated notes. Any such additional subordinated notes issued could be
considered part of the same series of notes under the subordinated debt indenture as the subordinated notes.
The subordinated notes will be issued on June 10, 2015 and will mature on June 10, 2025. The subordinated notes will bear interest at a fixed
rate of 4.400% per annum. Interest on the subordinated notes will be paid semi-annually on the 10th day of each June and December, commencing
December 10, 2015. All payments of interest will be made to the persons in whose names the subordinated notes are registered at the close of
business on the Business Day preceding the interest payment date.
The subordinated notes will rank subordinate and junior in right of payment to Citigroup's senior indebtedness, as described in "--
Subordination" in this prospectus supplement. On a consolidated basis, the aggregate principal amount

Prospectus Supplement
of senior indebtedness of Citigroup outstanding as of March 31, 2015 was approximately $224 billion. This senior indebtedness consisted of
approximately $185 billion of long-term debt, approximately $11 billion of commercial paper and approximately $28 billion of other short-term
borrowings.
If conditions (1) through (3) listed in the section "United States Federal Income Tax Considerations -- Non-United States Holders" in the
accompanying prospectus are not satisfied, a non-United States holder generally will be subject to a United States withholding tax of 30% on
interest payments made on a note. Non-United States holders are advised that IRS Form W-8BEN-E, rather than IRS Form W-8BEN, should be
used by entities that are beneficial owners of a payment or another entity that is the beneficial owner.
The following disclosure replaces in full the section "United States Federal Income Tax Considerations -- FATCA Legislation May Impose
Withholding Tax on Debt Securities Held by or through Foreign Entities" in the accompanying prospectus:
Additional Withholding Requirements
Withholding at a rate of 30% generally will be required in certain circumstances on interest in respect of, and after December 31, 2016, gross
proceeds from the disposition of, notes held by or through certain financial institutions (including investment funds), unless such institution
(i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts
maintained by, the institution that are owned by U.S. persons and to withhold on certain payments or (ii) if required under an intergovernmental
agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange
such information with the U.S. authorities. An intergovernmental agreement between the United States and applicable foreign country may modify
these requirements. Accordingly, the entity through which the notes are held will affect the determination of whether such withholding is required.
Similarly, interest in respect of and, after December 31, 2016, gross proceeds from the disposition of, notes held by an investor that is a non-
financial non-U.S. entity that does not qualify under certain exemptions generally will be subject to withholding at a rate of 30%, unless such
entity either (i) certifies to Citigroup that such entity does not have any "substantial United States owners" or (ii) provides certain information
regarding the entity's "substantial United States owners," which Citigroup will in turn provide to the United States Department of the Treasury.
You are encouraged to consult your tax advisor regarding the possible implications of these rules on an investment in the notes.
Subordination
The subordinated notes will be issued under the subordinated debt indenture, will be unsecured obligations of Citigroup, will rank
subordinated and junior in right of payment, to the extent set forth in the indenture, to all "Senior Indebtedness" (as defined below) of Citigroup
and will rank equally with all other unsecured and subordinated indebtedness of Citigroup, whether existing at the time of issuance or created
thereafter, other than subordinated indebtedness which is designated as junior to the subordinated notes.
If Citigroup defaults in the payment of any principal of, or premium, if any, or interest on any Senior Indebtedness when it becomes due and
payable after any applicable grace period, then, unless and until the default is cured or waived or ceases to exist, Citigroup cannot make a payment
on account of or redeem or otherwise acquire the subordinated notes. Nevertheless, holders of subordinated notes may still receive and retain:

· securities of Citigroup or any other corporation provided for by a plan of reorganization or readjustment that are subordinate, at least to the

same extent that the subordinated notes are subordinate to Senior Indebtedness; and


· payments made from a defeasance trust as described below.
If there is any insolvency, bankruptcy, liquidation or other similar proceeding relating to Citigroup, its creditors or its property, then all
Senior Indebtedness must be paid in full before any payment may be made to any holders of subordinated notes. Holders of subordinated notes
must return and deliver any payments received by them, other than in a plan of reorganization or through a defeasance trust as described in the
accompanying prospectus, directly to the holders of Senior Indebtedness until all Senior Indebtedness is paid in full.

S-5
Table of Contents
In addition, the subordinated notes may be fully subordinated to interests held by the U.S. government in the event of a receivership,
insolvency or similar proceeding, including a proceeding under the "orderly liquidation authority" provisions of the Dodd-Frank Wall Street
Reform and Consumer Protection Act of 2010.
"Senior Indebtedness" means:

(1)
the principal, premium, if any, and interest in respect of (A) indebtedness for money borrowed and (B) indebtedness evidenced by
securities, notes, debentures, bonds or other similar instruments issued by Citigroup, including all indebtedness (whether now or

(D) any guarantee in respect of any preferred securities, capital securities or preference stock of a Citigroup Trust;
(E) any indebtedness or any guarantee that is by its terms subordinated to, or ranks equally with, the subordinated notes and the
issuance of which (x) has received the concurrence or approval of the staff of the Federal Reserve Bank of New York or the staff of the

or any applicable concurrence or approval of the Federal Reserve Bank of New York or its staff.

of this prospectus supplement and to certain dealers at the public offering price less a concession not in excess of 0.270% of the principal amount of
the subordinated notes. The underwriters may allow, and such dealers may reallow, a concession to certain other dealers not in excess of 0.160% of
the principal amount of the subordinated 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 subordinated notes subject to prior sale and their acceptance of the subordinated 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 subordinated 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 subordinated notes than they are required to

Prospectus Supplement
purchase in the offering.


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

· Covering transactions involve purchases of the subordinated 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 subordinated notes. They may also cause the price of the subordinated 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 subordinated notes are a new series of securities with no established trading market. Citigroup will apply for listing and trading of the
subordinated 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 subordinated notes, as permitted by applicable laws and regulations. The underwriters are not obligated, however, to make a market
in the subordinated 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 subordinated 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 subordinated 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 subordinated notes, either directly or indirectly, without
the specific written approval of the accountholder.

Table of Contents
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 subordinated 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 subordinated notes will be made against payment therefor on or about June 10, 2015, 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
subordinated notes on the date hereof or the next business day will be required, by virtue of the fact that the subordinated 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 subordinated 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 subordinated 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 subordinated 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.

each Relevant Member State.
