Fixed to Floating Rate Range Accrual Notes Contingent on 3-month U.S. Dollar LIBOR Due March    , 2021
§
The notes offered by this pricing supplement will pay interest at a fixed rate equal to 3.50% per annum for the first three years after issuance.  Thereafter, interest will accrue on the notes at a variable annual rate equal to 3-month U.S. Dollar LIBOR (reset quarterly) plus 1.00%, but only for each elapsed day on which 3-month U.S. Dollar LIBOR is less than or equal to 4.00% per annum.  After the first three years, no interest will accrue on the notes on any elapsed day on which 3-month U.S. Dollar LIBOR is greater than 4.00% per annum.  Accordingly, after the first three years, investors in the notes will benefit if 3-month U.S. Dollar LIBOR increases moderately from current levels, and investors in the notes will be adversely affected if 3-month U.S. Dollar LIBOR either increases above 4.00% per annum or remains near or below current low levels.  It is possible that you will receive low or no interest on the notes after the first three years.
§
The notes are unsecured senior debt securities issued by Citigroup Inc.  Investors in the notes must be willing to accept (i) an investment that may have limited or no liquidity and (ii) the risk of not receiving any amount due under the notes if we default on our obligations.

(1) Citigroup Inc. currently expects that the estimated value of the notes on the pricing date will be between $940.00 and $985.00 per note, which will be less than the issue price. The estimated value of the notes is based on CGMI’s proprietary pricing models and our internal funding rate. It is not an indication of actual profit to CGMI or other of our affiliates, nor is it an indication of the price, if any, at which CGMI or any other person may be willing to buy the notes from you at any time after issuance. See “Valuation of the Notes” in this pricing supplement.
(2) The underwriting fee is variable but will not exceed $15.00 per note. The per note proceeds to issuer above represent the minimum per note proceeds to Citigroup Inc., assuming the maximum per note underwriting fee. For more information on the distribution of the notes, see “Supplemental Plan of Distribution” in this pricing supplement. In addition to the underwriting fee, CGMI and its affiliates may profit from expected hedging activity related to this offering, even if the value of the notes declines. See “Use of Proceeds and Hedging” in the accompanying prospectus.
The notes involve risks not associated with conventional debt securities. See “Summary Risk Factors” beginning on page PS-3.
Neither the Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the notes or determined that this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus is truthful or complete.

Additional Information
 
General. The terms of the notes are set forth in the accompanying product supplement, prospectus supplement and prospectus, as supplemented by this pricing supplement. The accompanying product supplement, prospectus supplement and prospectus contain important disclosures that are not repeated in this pricing supplement. For example, certain events may occur that could affect the amount of any variable quarterly coupon payment you receive. These events and their consequences are described in the accompanying product supplement in the section “Description of the Notes—Terms Related to an Underlying Rate” and not in this pricing supplement.  It is important that you read the accompanying product supplement, prospectus supplement and prospectus together with this pricing supplement before deciding whether to invest in the notes. Certain terms used but not defined in this pricing supplement are defined in the accompanying product supplement.
 
Additional terms relating to the accrual condition.  For purposes of determining whether the accrual condition is satisfied on any elapsed day, if 3-month U.S. Dollar LIBOR is not available for any reason on that day (including weekends and holidays), then 3-month U.S. Dollar LIBOR will be assumed to be the same as on the immediately preceding elapsed day (subject to the discussion in the section “Description of the Notes—Terms Related to an Underlying Rate—Discontinuance of a U.S. Dollar LIBOR Rate” in the accompanying product supplement).  In addition, for all elapsed days from and including the fourth-to-last London business day in an accrual period to and including the last elapsed day of that accrual period, for purposes of the accrual condition, 3-month U.S. Dollar LIBOR will not be observed and will be assumed to be the same as on the elapsed day immediately preceding such unobserved days.  Notwithstanding statements in the accompanying product supplement that the satisfaction of the accrual condition will depend on the level of an equity index, the accrual condition for these notes is based solely on 3-month U.S. Dollar LIBOR and not on the level of any equity index.
 
Calculation agent.  Our affiliate, Citibank, N.A., will be the calculation agent for the notes.
 
Hypothetical Examples
 
The tables below present examples of the hypothetical variable coupon rate and hypothetical variable quarterly coupon payments after the first three years of the term of the notes based on the number of accrual days in a particular accrual period and different assumptions about 3-month U.S. Dollar LIBOR on the reset determination date for that accrual period.  For illustrative purposes only, the table assumes an accrual period that contains 90 elapsed days.  The actual coupon payment for any coupon payment date after March   , 2017 (expected to be March 28, 2017) will depend on the actual number of accrual days and elapsed days during the related accrual period and the actual 3-month U.S. Dollar LIBOR rate on the reset determination date for that accrual period.  The variable coupon rate for each accrual period will apply only to that accrual period.

Summary Risk Factors
 
An investment in the notes is significantly riskier than an investment in conventional debt securities.  The notes are subject to all of the risks associated with an investment in our conventional debt securities, including the risk that we may default on our obligations under the notes, and are also subject to risks associated with 3-month U.S. Dollar LIBOR.  Accordingly, the notes are suitable only for investors who are capable of understanding the complexities and risks of the notes.  You should consult your own financial, tax and legal advisers as to the risks of an investment in the notes and the suitability of the notes in light of your particular circumstances.
 
The following is a summary of certain key risk factors for investors in the notes.  You should read this summary together with the more detailed description of risks relating to an investment in the notes contained in the section “Risk Factors Relating to the Notes” beginning on page EA-6 in the accompanying product supplement.  You should also carefully read the risk factors included in the documents incorporated by reference in the accompanying prospectus, including our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which describe risks relating to our business more generally.
 
§
After the first three years, the amount of interest payable on the notes will vary and may be zero.  After the first three years of the term of the notes, interest will accrue on the notes at a variable annual rate equal to 3-month U.S. Dollar LIBOR (reset quarterly) plus 1.00%, but only for each elapsed day on which 3-month U.S. Dollar LIBOR is less than or equal to 4.00% per annum.  After the first three years, no interest will accrue on the notes on any elapsed day on which 3-month U.S. Dollar LIBOR is greater than 4.00% per annum.  It is possible that 3-month U.S. Dollar LIBOR may be greater than 4.00% per annum throughout the final four years of the term of the notes, so that you will receive no interest at all during that period.  It is also possible that 3-month U.S. LIBOR may remain near or below its current low levels so that, although interest will accrue on the notes, the resulting interest payments to you are lower than you may expect.  The notes are not a suitable investment for investors who require the certainty of regular fixed income payments after the first three years.
 
§
The notes may perform more poorly than conventional floating rate debt securities.  The notes are not conventional floating rate debt securities.  The interest rate payable on a conventional floating rate debt security linked to 3-month U.S. Dollar LIBOR would increase with any increase in 3-month U.S. Dollar LIBOR and, if subject to a cap, would be equal to the cap if 3-month U.S. Dollar LIBOR exceeds the cap.  By contrast, if 3-month U.S. Dollar LIBOR exceeds 4.00% per annum after the first three years of the term of the notes, the notes will not accrue any interest at all.  You should carefully consider whether the fixed interest rate during the first three years and the spread of 1.00% over 3-month U.S. Dollar LIBOR after the first three years are sufficient compensation to you for assuming the risk of receiving no interest at all if 3-month U.S. Dollar LIBOR exceeds 4.00% per annum.
 
§
Although the notes provide for the repayment of the stated principal amount at maturity, you may nevertheless suffer a loss on your investment in real value terms if you receive low or no variable coupon payments after the first three years.  This is because inflation may cause the real value of the stated principal amount to be less at maturity than it is at the time you invest, and because an investment in the notes represents a forgone opportunity to invest in an alternative asset that does generate a positive real return after the first three years of the term of the notes.  The total interest payable on the notes may be lower than the yield on a conventional fixed-rate debt security of ours of comparable maturity.  You should carefully consider

whether an investment that may not provide for any interest after the first three years, or may provide a return that is lower than the return on alternative investments, is appropriate for you.
 
§
The notes are subject to the credit risk of Citigroup Inc.  If we default on our obligations under the notes, you may not receive anything owed to you under the notes.
 
§
The notes will not be listed on a securities exchange and you may not be able to sell them prior to maturity.  The notes will not be listed on any securities exchange.  Therefore, there may be little or no secondary market for the notes.  CGMI currently intends to make a secondary market in relation to the notes and to provide an indicative bid price for the notes on a daily basis. Any indicative bid price for the notes provided by CGMI will be determined in CGMI’s sole discretion, taking into account prevailing market conditions and other relevant factors, and will not be a representation by CGMI that the notes can be sold at that price, or at all.  CGMI may suspend or terminate making a market and providing indicative bid prices without notice, at any time and for any reason.  If CGMI suspends or terminates making a market, there may be no secondary market at all for the notes because it is likely that CGMI will be the only broker-dealer that is willing to buy your notes prior to maturity.  Accordingly, an investor must be prepared to hold the notes until maturity.
 
§
Sale of the notes prior to maturity may result in a loss of principal.  You will be entitled to receive at least the full stated principal amount of your notes, subject to the credit risk of Citigroup Inc., only if you hold the notes to maturity. The value of the notes may fluctuate during the term of the notes, and if you are able to sell your notes prior to maturity, you may receive less than the full stated principal amount of your notes.
 
§
The estimated value of the notes on the pricing date, based on CGMI’s proprietary pricing models and our internal funding rate, will be less than the issue price.  The difference is attributable to certain costs associated with selling, structuring and hedging the notes that are included in the issue price.  These costs include (i) the selling concessions paid in connection with the offering of the notes, (ii) hedging and other costs incurred by us and our affiliates in connection with the offering of the notes and (iii) the expected profit (which may be more or less than actual profit) to CGMI or other of our affiliates in connection with hedging our obligations under the notes.  These costs adversely affect the economic terms of the notes because, if they were lower, the economic terms of the notes would be more favorable to you.  The economic terms of the notes are also likely to be adversely affected by the use of our internal funding rate, rather than our secondary market rate, to price the notes.  See “The estimated value of the notes would be lower if it were calculated based on our secondary market rate” below.
 
§
The estimated value of the notes was determined for us by our affiliate using proprietary pricing models.  CGMI derived the estimated value disclosed on the cover page of this pricing supplement from its proprietary pricing models.  In doing so, it may have made discretionary judgments about the inputs to its models, such as the volatility of 3-month U.S. Dollar LIBOR and interest rates generally.  CGMI’s views on these inputs may differ from your or others’ views, and as an underwriter in this offering, CGMI’s interests may conflict with yours.  Both the models and the inputs to the models may prove to be wrong and therefore not an accurate reflection of the value of the notes.  Moreover, the estimated value of the notes set forth on the cover page of this pricing supplement may differ from the value that we or our affiliates may determine for the notes for other purposes, including for accounting purposes.  You should not invest in the notes because of the estimated value of the notes. Instead, you should be willing to hold the notes to maturity irrespective of the initial estimated value.
 
§
The estimated value of the notes would be lower if it were calculated based on our secondary market rate.  The estimated value of the notes included in this pricing supplement is calculated based on our internal funding rate, which is the rate at which we are willing to borrow funds through the issuance of the notes.  Our internal funding rate is generally lower than the market rate implied by traded instruments referencing our debt obligations in the secondary market for those debt obligations, which we refer to as our secondary market rate.  If the estimated value included in this pricing supplement were based on our secondary market rate, rather than our internal funding rate, it would likely be lower.  We determine our internal funding rate based on factors such as the costs associated with the notes, which are generally higher than the costs associated with conventional debt securities, and our liquidity needs and preferences.  Our internal funding rate is not the same as the coupon that is payable on the notes.
 
§
The estimated value of the notes is not an indication of the price, if any, at which CGMI or any other person may be willing to buy the notes from you in the secondary market.  Any such secondary market price will fluctuate over the term of the notes based on the market and other factors described in the next risk factor.  Moreover, unlike the estimated value included in this pricing supplement, any value of the notes determined for purposes of a secondary market transaction will be based on our secondary market rate, which will likely result in a lower value for the notes than if our internal funding rate were used.  In addition, any secondary market price for the notes will be reduced by a bid-ask spread, which may vary depending on the aggregate stated principal amount of the notes to be purchased in the secondary market transaction, and the expected cost of unwinding related hedging transactions.  As a result, it is likely that any secondary market price for the notes will be less than the issue price.
 
§
The value of the notes prior to maturity will fluctuate based on many unpredictable factors. The value of your notes prior to maturity will fluctuate based on the level and volatility of 3-month U.S. Dollar LIBOR and a number of other factors, including interest rates generally, the time remaining to maturity of the notes and our creditworthiness, as reflected in our secondary market rate.  You should understand that the value of your notes at any time prior to maturity may be significantly less than the issue price.
 
§
Immediately following issuance, any secondary market bid price provided by CGMI, and the value that will be indicated on any brokerage account statements prepared by CGMI or its affiliates, will reflect a temporary upward adjustment. The

amount of this temporary upward adjustment will steadily decline to zero over the temporary adjustment period.  See “Valuation of the Notes” in this pricing supplement.
 
§
Our offering of the notes is not a recommendation of an investment linked to 3-month U.S. Dollar LIBOR.  The fact that we are offering the notes does not mean that we believe that investing in an instrument linked to 3-month U.S. Dollar LIBOR is likely to achieve favorable returns.  In fact, as we are part of a global financial institution, our affiliates may have positions (including short positions) in instruments related to 3-month U.S. Dollar LIBOR, and may publish research or express opinions, that in each case are inconsistent with an investment linked to 3-month U.S. Dollar LIBOR.
 
§
3-month U.S. Dollar LIBOR and the manner in which it is calculated may change in the future.  The method by which 3-month U.S. Dollar LIBOR is calculated may change in the future, as a result of governmental actions, actions by the publisher of 3-month U.S. Dollar LIBOR or otherwise.  We cannot predict whether the method by which 3-month U.S. Dollar LIBOR is calculated will change or what the impact of any such change might be.  Any such change could affect the level of 3-month U.S. Dollar LIBOR in a way that has a significant adverse effect on the notes.
 
§
The calculation agent, which is an affiliate of ours, will make important determinations with respect to the notes.  If certain events occur, such as the unavailability or discontinuance of 3-month U.S. Dollar LIBOR, Citibank, N.A., as calculation agent, will be required to make discretionary judgments that could significantly affect any coupon payment you receive.  In making these judgments, the calculation agent’s interests as an affiliate of ours could be adverse to your interests as a holder of the notes.
 
Information about 3-month U.S. Dollar LIBOR
 
3-month U.S. Dollar LIBOR is a daily reference rate based on the interest rates at which banks borrow funds from each other in U.S. dollars for a term of three months, in marketable size, in the London interbank market.
 
For information about how 3-month U.S. Dollar LIBOR will be determined on each date of determination, see “Description of the Notes—Terms Related to an Underlying Rate—Determining a U.S. Dollar LIBOR Rate” in the accompanying product supplement.
 
Historical Information
 
3-month U.S. Dollar LIBOR was 0.2357% on March 7, 2014. The graph below shows the level of 3-month U.S. Dollar LIBOR for each day it was available from January 2, 2004 to March 7, 2014.  We obtained the values below from Bloomberg L.P., without independent verification.  You should not take the historical performance of 3-month U.S. Dollar LIBOR as an indication of future performance.

United States Federal Tax Considerations
 
In the opinion of our tax counsel, Davis Polk & Wardwell LLP, the notes should be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, as described in the section of the accompanying prospectus supplement called “United States Federal Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Contingent Payment Debt Instruments.”
 
If you are a U.S. Holder, you will be required to recognize interest income at the “comparable yield,” which generally is the yield at which we could issue a fixed-rate debt instrument with terms similar to those of the notes, including the level of subordination, term, timing of payments and general market conditions, but excluding any adjustments for the riskiness of the contingencies or the liquidity of the notes. We are required to construct a “projected payment schedule” in respect of the notes representing a payment or a series of payments the amount and timing of which would produce a yield to maturity on the notes equal to the comparable yield.  The amount of interest you include in income in each taxable year based on the comparable yield will be adjusted upward or downward to reflect the difference, if any, between the actual and projected payments on the notes as determined under the projected payment schedule.
 
We have determined that the comparable yield for a note is a rate of   %, compounded quarterly, and that the projected payment schedule with respect to a note consists of the following payments:

Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amounts that we will pay on the notes.
 
Upon the sale, exchange or retirement of the notes, you generally will recognize gain or loss equal to the difference between the proceeds received and your adjusted tax basis in the notes.  Your adjusted tax basis will equal your purchase price for the notes increased by interest income previously included on the notes (without regard to the adjustments described above) and decreased by prior payments according to the projected payment schedule.  Any gain generally will be treated as ordinary income, and any loss will be treated as ordinary income to the extent of prior net interest inclusions on the note and as capital loss thereafter.
 
If you are a Non-U.S. Holder of notes, you generally will not be subject to U.S. federal withholding or income tax in respect of amounts paid to you on the notes provided that (i) income in respect of the notes is not effectively connected with your conduct of a trade or business in the United States, and (ii) you comply with the applicable certification requirements.  See “United States Federal Tax Considerations—Tax Consequences to Non-U.S. Holders” in the accompanying prospectus supplement for a more detailed discussion of the rules applicable to Non-U.S. Holders of the notes.
 
You should read the section entitled “United States Federal Tax Considerations” in the accompanying prospectus supplement.  The preceding discussion, when read in combination with that section, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of owning and disposing of the notes.
 
You should also consult your tax adviser regarding all aspects of the U.S. federal tax consequences of an investment in the notes and any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

CGMI, an affiliate of Citigroup Inc. and the underwriter of the sale of the notes, is acting as principal and will receive an underwriting fee of up to $15.00 for each $1,000.00 note sold in this offering.  From this underwriting fee, CGMI will pay selected dealers and their financial advisers collectively a variable selling concession of up to $15.00 for each $1,000.00 note they sell.
 
CGMI is an affiliate of ours. Accordingly, this offering 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 Inc. or its subsidiaries have investment discretion will not be permitted to purchase the notes, either directly or indirectly, without the prior written consent of the client.
 
See “Plan of Distribution; Conflicts of Interest” in the accompanying product supplement and “Plan of Distribution” in each of the accompanying prospectus supplement and prospectus for additional information.
 
A portion of the net proceeds from the sale of the notes will be used to hedge our obligations under the notes.  We expect to hedge our obligations under the notes through CGMI or other of our affiliates. CGMI or such other of our affiliates may profit from this hedging activity even if the value of the notes declines.  For additional information on the ways in which our counterparties may hedge our obligations under the notes, see “Use of Proceeds and Hedging” in the accompanying prospectus.
 
Valuation of the Notes
 
CGMI calculated the estimated value of the notes set forth on the cover page of this pricing supplement based on proprietary pricing models. CGMI’s proprietary pricing models generated an estimated value for the notes by estimating the value of a hypothetical package of financial instruments that would replicate the payout on the notes, which consists of a fixed-income bond (the “bond component”) and one or more derivative instruments underlying the economic terms of the notes (the “derivative component”). CGMI calculated the estimated value of the bond component using a discount rate based on our internal funding rate. CGMI calculated the estimated value of the derivative component based on a proprietary derivative-pricing model, which generated a theoretical price for the instruments that constitute the derivative component based on various inputs, including the factors described under “Summary Risk Factors—The value of the notes prior to maturity will fluctuate based on many unpredictable factors” in this pricing supplement, but not including our creditworthiness. These inputs may be market-observable or may be based on assumptions made by CGMI in its discretionary judgment.
 
The estimated value of the notes is a function of the terms of the notes and the inputs to CGMI’s proprietary pricing models. The range for the estimated value of the notes set forth on the cover page of this preliminary pricing supplement reflects uncertainty on the date of this preliminary pricing supplement about the inputs to CGMI’s proprietary pricing models on the pricing date.
 
For a period of approximately four months following issuance of the notes, the price, if any, at which CGMI would be willing to buy the notes from investors, and the value that will be indicated for the notes on any brokerage account statements prepared by CGMI or its affiliates (which value CGMI may also publish through one or more financial information vendors), will reflect a temporary upward adjustment from the price or value that would otherwise be determined. This temporary upward adjustment represents a portion of the hedging profit expected to be realized by CGMI or its affiliates over the term of the notes. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the four-month temporary adjustment period.
