Ltd. and Citigroup Global Markets Asia Limited, will receive a concession, and financial advisors employed by Citigroup Global Markets Inc. or such broker-dealers will receive a fixed sales commission, of $10.00 for each note they sell. Citigroup Global Markets Inc. will pay selected dealers not affiliated with Citigroup Global Markets Inc. a selling concession of up to $10.00 for each $1,000 note they sell.  Additionally, it is possible that Citigroup Global Markets Inc. and its affiliates may profit from expected hedging activity related to this offering, even if the value of the notes declines.

Risk Factors
 
The following is a non-exhaustive list of certain key risk factors for investors in the notes. For further discussion of these and other risks, you should read the sections entitled “Risk Factors” in the accompanying prospectus supplement.  We also urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the notes.
 
n
The amount of interest payable on the notes will vary.  The notes differ from conventional fixed-rate debt securities in that the interest payable on the notes will vary after the first two years of the term of the notes based on the level of three-month U.S. dollar LIBOR. From and including May    , 2014 (expected to be May 30, 2014) to but excluding the maturity date, the notes will bear interest during each quarterly interest period at a per annum rate equal to the level of three-month U.S. dollar LIBOR determined on the second London business day prior to the first day of the applicable interest period plus a spread of 1.10%, subject to a maximum interest rate of 5.00% per annum for any interest period. The per annum interest rate that is determined on the relevant interest determination date will apply to the entire interest period following that interest determination date, even if three-month U.S. dollar LIBOR increases during that interest period, but is applicable only to that quarterly interest period; interest payments for any other quarterly interest period will vary.
 
n
The interest rate applicable to the notes will be subject to a maximum per annum rate. The interest rate applicable to the notes from and including May    , 2014 (expected to be May 30, 2014) to but excluding the maturity date cannot exceed 5.00% per annum for any interest period.  As a result, if the level of three-month U.S. dollar LIBOR applicable to any interest period during the last year of the term of the notes is greater than 3.90% (taking into account that a spread of 1.10% will be added to the level of three-month U.S. dollar LIBOR on the applicable interest determination date), the notes will provide you less interest income than an investment in a similar instrument that is not subject to a maximum per annum interest rate.
 
n
The yield on the notes may be lower than the yield on a standard debt security of comparable maturity. During the first two years of the term of the notes, the notes will bear interest at a rate of 2.00%.  From and including May    , 2014 (expected to be May 30, 2014) to but excluding the maturity date, the notes will bear interest during each quarterly interest period at the per annum rate equal to the level of three-month U.S. dollar LIBOR determined on the second London business day prior to the first day of the applicable interest period plus a spread of 1.10%, subject to a maximum interest rate of 5.00% per annum for any interest period.  As a result, the effective yield on your notes may be less than that which would be payable on a conventional fixed-rate, non-callable debt security of Citigroup Funding Inc. (“Citigroup Funding”) (guaranteed by Citigroup Inc.) of comparable maturity.
 
n
The notes are subject to the credit risk of Citigroup Inc., and any actual or anticipated changes to its credit ratings or credit spreads may adversely affect the value of the notes. You are subject to the credit risk of Citigroup Inc., Citigroup Funding’s parent company and the guarantor of any payments due on the notes.  The notes are not guaranteed by any entity other than Citigroup Inc. If Citigroup Inc. defaults on its guarantee obligations under the notes, your investment would be at risk and you could lose some or all of your investment.  As a result, the value of the notes will be affected by changes in the market’s view of Citigroup Inc.’s creditworthiness. Any decline, or anticipated decline, in Citigroup Inc.’s credit ratings or increase, or anticipated increase, in the credit spreads charged by the market for taking Citigroup Inc. credit risk is likely to adversely affect the value of the notes.
 
n
The notes will not be listed on any securities exchange, and secondary trading may be limited. The notes will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the notes. Citigroup Global Markets Inc. (“Citigroup Global Markets”) may, but is not obligated to, make a market in the notes.  If Citigroup Global Markets does make a market in the notes, it may discontinue doing so at any time. Because we do not expect that other broker-dealers will participate significantly in any secondary market that may develop for the notes, the price at which you may be able to sell your notes is likely to depend on the price, if any, at which Citigroup Global Markets is willing to transact. If, at any time, Citigroup Global Markets were not to make a market in the notes, it is likely that there would be no secondary market for the notes. Accordingly, you should be willing to hold your notes to maturity.
 
n
Secondary market sales of the notes may result in a loss of principal.  You will be entitled to receive at least the full principal amount of your notes, subject to the credit risk of Citigroup Inc., only if you hold the notes to maturity.  Because the value of the notes may fluctuate, if you are able to sell your notes in the secondary market prior to maturity, you may receive less than the principal amount of the notes.
 
n
The inclusion of underwriting fees and projected profit from hedging in the issue price is likely to adversely affect secondary market prices. Assuming no changes in market conditions or other relevant factors, the price, if any, at which Citigroup Global Markets is willing to purchase the notes in secondary market transactions will likely be lower than the issue price since the issue price will include, and secondary market prices are likely to exclude, underwriting fees paid with respect to the notes, as well as the cost of hedging our obligations under the notes. The cost of hedging includes the projected profit that our affiliates may realize in consideration for assuming the risks inherent in managing the hedging transactions. The secondary market prices for the notes are also likely to be reduced by the costs of unwinding the related hedging transactions. Our affiliates may realize a profit from the expected hedging activity even if the value of the notes declines. In addition, any secondary market prices for the notes may differ from values determined by pricing models used by Citigroup Global Markets, as a result of dealer discounts, mark-ups or other transaction costs.

n
The price at which you may be able to sell your notes prior to maturity will depend on a number of factors and may be substantially less than you originally invest. Numerous factors will influence the value of the notes in any secondary market that may develop and the price at which Citigroup Global Markets may be willing to purchase the notes in any such secondary market, including:  the level and volatility of three-month U.S-dollar LIBOR, interest rates in the market, the time remaining to maturity, hedging activities by our affiliates, fees and projected hedging fees and profits, and any actual or anticipated changes in the credit ratings, financial condition and results of Citigroup Funding and Citigroup Inc. As a result, the value of the notes will vary and may be less than the issue price at any time prior to maturity. Sale of the notes prior to maturity may result in a loss.
 
n
The calculation agent, which is an affiliate of the issuer, will make determinations with respect to the notes. Citigroup Financial Products, Inc., the calculation agent for the notes, is an affiliate of ours. As calculation agent, Citigroup Financial Products, Inc. will determine, among other things, the level of three-month U.S. dollar LIBOR and will calculate the interest payable to you on each interest payment date.  Any of these determinations or calculations made by Citigroup Financial Products, Inc. in its capacity as calculation agent, including with respect to the calculation of the level of three-month U.S. dollar LIBOR in the event of the unavailability of the level of three-month U.S. dollar LIBOR, may adversely affect the amount of one or more interest payments to you.
 
n
Hedging and trading activity by Citigroup Funding could result in a conflict of interest. In anticipation of the sale of the notes, we expect one or more of our affiliates to enter into hedge transactions. This hedging activity will likely involve trading in instruments, such as options, swaps or futures, based upon three-month U.S. dollar LIBOR. This hedging activity may present a conflict between your interest in the notes and the interests our affiliates have in executing, maintaining and adjusting their hedge transactions because it could affect the price at which our affiliate Citigroup Global Markets may be willing to purchase your notes in the secondary market. Because hedging our obligations under the notes involves risk and may be influenced by a number of factors, it is possible that our affiliates may profit from the hedging activity, even if the value of the notes declines.
 
n
The historical performance of three-month U.S. dollar LIBOR is not an indication of its future performance. The historical performance of three-month U.S. dollar LIBOR, which is included in this pricing supplement, should not be taken as an indication of the future performance of three-month U.S. dollar LIBOR during the term of the notes. Changes in the level of three-month U.S. dollar LIBOR will affect the value of the notes, but it is impossible to predict whether the level of three-month U.S. dollar LIBOR will rise or fall.
 
n
You will have no rights against the publishers of three-month U.S. dollar LIBOR. You will have no rights against the publishers of three-month U.S. dollar LIBOR even though the amount you receive on each interest payment date after the first two years of the term of the notes will depend upon the level of three-month U.S. dollar LIBOR. The publishers of three-month U.S. dollar LIBOR are not in any way involved in this offering and have no obligations relating to the notes or the holders of the notes.

General Information
 
Interest:
The        of each February, May, August and November (expected to be the 30th of each such month), or the last day of the month in the case of February, beginning on August    , 2012 (expected to be August 30, 2012) and ending on the maturity date, will be an interest payment date.  If a scheduled interest payment date is not a business day, interest will be paid on the next succeeding business day with the same force and effect as if it has been paid on the scheduled interest payment date.  No additional interest will accrue as a result of delayed payment.
 
Interest will be payable to the persons in whose names the notes are registered at the close of business on the business day preceding each interest payment date (each such day, a “regular record date”).
United States federal income tax considerations:
In the opinion of our counsel, Davis Polk & Wardwell LLP, under current law, the notes will be treated as “variable rate debt instruments” that provide for a single fixed rate followed by a qualified floating rate (“QFR”) for U.S. federal income tax purposes.  Under applicable Treasury Regulations, in order to determine the amount of qualified stated interest and original issue discount (“OID”) in respect of the notes, an equivalent fixed rate debt instrument must be constructed.  The equivalent fixed rate debt instrument is constructed in the following manner: (i) first, the initial fixed rate is converted to a QFR that would preserve the fair market value of the notes, and (ii) second, each QFR (including the QFR determined under (i) above) is converted to a fixed rate substitute (which will generally be the value of that QFR as of the issue date of the notes).  Based on the application of these rules to the notes, we expect that the notes will not be issued with OID, in which case stated interest on the notes will be taxable to a United States holder as ordinary interest income at the time it accrues or is received in accordance with the holder’s method of tax accounting.  However, whether the notes are treated as issued with OID will be determined as of the pricing date for the notes, and, if the notes are issued with OID, a United States holder (as defined in the accompanying prospectus supplement) will be required to include the OID in income for federal income tax purposes as it accrues, in accordance with a constant-yield method based on a compounding of interest.
 
Upon the sale or other taxable disposition of a note, a United States holder generally will recognize capital gain or loss equal to the difference between the amount realized on the disposition (other than amounts attributable to accrued qualified stated interest, which will be treated as interest income) and the holder’s tax basis in the note.  Such gain or loss generally will be long-term capital gain or loss if the United States holder has held the note for more than one year at the time of disposition.
 
Non-United States holders (as defined in the accompanying prospectus supplement) generally will not be subject to U.S. federal withholding or income tax with respect to interest (or OID, if any) paid on and amounts received on the sale, exchange or retirement of the notes if they fulfill certain certification requirements.  Special rules apply to non-United States holders whose gain on the notes is effectively connected with the conduct of a U.S. trade or business or who are individuals present in the United States for 183 days or more in a taxable year.
 
Both U.S. and non-U.S. persons considering an investment in the notes should read the section entitled “Certain United States Federal Income Tax Considerations” in the accompanying prospectus supplement.  The preceding discussion when read in combination with that section, constitutes the full opinion of our counsel regarding the material U.S. federal income tax consequences of owning and disposing of the notes.
 
Prospective investors in the notes should consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the notes, including any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.
Trustee:
The Bank of New York Mellon (as successor trustee under an indenture dated June 1, 2005) will serve as trustee for the notes.
Use of proceeds and hedging:
The net proceeds received from the sale of the notes will be used for general corporate purposes and, in part, in connection with hedging our obligations under the notes through one or more of our affiliates.
 
Hedging activities related to the notes by one or more of our affiliates will likely involve trading in one or more instruments, such as options, swaps and/or futures, based on three-month U.S. dollar LIBOR and/or taking positions in any other available securities or instruments that we may wish to use in connection with such hedging. It is possible that our affiliates may profit from this hedging activity, even if the value of the notes declines. Profit or loss from this hedging activity could affect the price at which Citigroup Funding’s affiliate, Citigroup Global Markets, may be willing to purchase your notes in the secondary market. For further information on our use of proceeds and hedging, see “Use of Proceeds and Hedging” in the accompanying prospectus.
ERISA and IRA purchase considerations:
Each purchaser of the notes or any interest therein will be deemed to have represented and warranted on each day from and including the date of its purchase or other acquisition of the notes through and including the date of disposition of such notes that either:
 
 
(a)
it is not (i) an employee benefit plan subject to the fiduciary responsibility provisions of ERISA,

    (ii) an entity with respect to which part or all of its assets constitute assets of any such employee benefit plan by reason of C.F.R. 2510.3-101 or otherwise, (iii) a plan described in Section 4975(e)(1) of the Internal Revenue Code of 1986,a s amended (the “Code”) (for example, individual retirement accounts, individual retirement annuities or Keogh plans), or (iv) a government or other plan subject to federal, state or local law substantially similar to the fiduciary responsibility provisions of ERISA or Section 4975 of the Code (such law, provisions and Section, collectively, a “Prohibited Transaction Provision” and (i), (ii), (iii) and (iv), collectively, “Plans”); or
     
 
(b)
if it is a Plan, either (A)(i) none of Citigroup Global Markets, its affiliates or any employee thereof is a Plan fiduciary that has or exercises any discretionary authority or control with respect to the Plan’s assets used to purchase the notes or renders investment advice with respect to those assets, and (ii) the Plan is paying no more than adequate consideration for the notes or (B) its acquisition and holding of the notes is not prohibited by a Prohibited Transaction Provision or is exempt therefrom.
 
 
The above representations and warranties are in lieu of the representations and warranties described in the section “ERISA Matters” in the accompanying prospectus supplement.  Please also refer to the section “ERISA Matters” in the accompanying prospectus.
Fees and selling concessions:
Citigroup Global Markets, an affiliate of Citigroup Funding and the underwriter of the sale of the notes, is acting as principal and will receive an underwriting fee of up to $10.00 for each note sold in this offering.  The actual underwriting fee per note will be equal to the selling concession provided to selected dealers, as described in this paragraph.  From this underwriting fee, certain broker-dealers affiliated with Citigroup Global Markets, including Citi International Financial Services, Citigroup Global Markets Singapore Pte. Ltd. and Citigroup Global Markets Asia Limited, will receive a concession, and financial advisors employed by Citigroup Global Markets or such broker-dealers will receive a fixed sales commission, of $10.00 for each note they sell.  Citigroup Global Markets will pay selected dealers not affiliated with Citigroup Global Markets a selling concession of up to $10.00 for each $1,000 note they sell.
 
Additionally, it is possible that Citigroup Global Markets and its affiliates may profit from expected hedging activity related to this offering, even if the value of the notes declines. You should refer to “Risk Factors” above and “Risk Factors—Citigroup Funding’s Hedging Activity Could Result in a Conflict of Interest” in the accompanying prospectus supplement and the section “Use of Proceeds and Hedging” in the accompanying prospectus.
 
Selling concessions allowed to dealers in connection with the offering may be reclaimed by the underwriter if, within 30 days of the offering, the underwriter repurchases the notes distributed by such dealers.
Supplemental information regarding plan of distribution; conflicts of interest:
The terms and conditions set forth in the Amended and Restated Global Selling Agency Agreement dated August 26, 2011 among Citigroup Funding, Citigroup Inc. and the agents named therein, including Citigroup Global Markets, govern the sale and purchase of the notes.

The notes will not be listed on any securities exchange.

Determination of Three-month U.S. Dollar LIBOR
Three-month U.S. dollar LIBOR is a daily reference rate fixed in U.S. dollars based on the interest rates at which banks borrow funds from each other for a term of three months, in marketable size, in the London interbank market. For any relevant date, three-month U.S. dollar LIBOR will equal the rate for three-month U.S. dollar LIBOR appearing on Reuters BBA page “LIBOR01” (or any successor page as determined by the calculation agent) as of 11:00 am (New York time) on that date.

If a rate for three-month U.S. dollar LIBOR is not published on Reuters BBA page “LIBOR01” (or any successor page as determined by the calculation agent) on any day on which the rate for three-month U.S. dollar LIBOR is required, then the calculation agent will request the principal London office of each of five major reference banks in the London interbank market, selected by the calculation agent, to provide such bank’s offered quotation to prime banks in the London interbank market for deposits in U.S. dollars in an amount that is representative of a single transaction in that market at that time (a “Representative Amount”) and for a term of three months as of 11:00 am (London time) on such day.  If at least two such quotations are so provided, the rate for three-month U.S. dollar LIBOR will be the arithmetic mean of such quotations.  If fewer than two such quotations are provided, the calculation agent will request each of three major banks in New York City to provide such bank’s rate to leading European banks for loans in U.S. dollars in a Representative Amount and for a term of three months as of approximately 11:00 am (New York City time) on such day.  If at least two such rates are so provided, the rate for three-month U.S. dollar LIBOR will be the arithmetic mean of such rates.  If fewer than two such rates are so provided, then the rate for three-month U.S. dollar LIBOR will be three-month U.S. dollar LIBOR in effect as of 11:00 am (New York City time) on the immediately preceding London business day.

A “business day” means any day that is not a Saturday or Sunday and that, in New York City, is not a day on which banking institutions are authorized or obligated by law or executive order to close.

A “London business day” means any day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.
