Market Linked Notes- Upside Participation to a Cap and Principal Return at Maturity Notes Linked to the EURO STOXX 50® Index due January 3, 2028

n Linked to the EURO STOXX 50® Index (the "underlying") n Unlike ordinary debt securities, the notes do not pay interest. Instead, the notes provide for a maturity payment amount that may be greater than or equal to the stated principal amount of the notes, depending on the performance of the underlying from the starting value to the ending value, subject to the maximum return. The maturity payment amount will reflect the following terms: n If the ending value is greater than the starting value, you will receive the stated principal amount plus a positive return equal to 100% of the percentage increase in the value of the underlying from the starting value, subject to a maximum return of at least 50.00% (to be determined on the pricing date) of the stated principal amount n If the ending value is less than or equal to the starting value, you will be repaid the stated principal amount but will not receive any positive return on your investment n Repayment of principal at maturity regardless of underlying performance (subject to issuer credit risk) n All payments on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.; if Citigroup Global Markets Holdings Inc. and Citigroup Inc. default on their obligations, you could lose some or all of your investment n No periodic interest payments or dividends n The notes will not be listed on any securities exchange and, accordingly, may have limited or no liquidity. You should not invest in the notes unless you are willing to hold them to maturity.

The notes have complex features and investing in the notes involves risks not associated with an investment in conventional debt securities. See "Summary Risk Factors" beginning on page PS-6 and "Risk Factors" beginning on page PS-5 of the accompanying product supplement and beginning on page S-1 of the accompanying prospectus supplement.

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 or the accompanying product supplement, underlying supplement, prospectus supplement and prospectus are truthful or complete. Any representation to the contrary is a criminal offense.

The notes are unsecured debt obligations issued by Citigroup Global Markets Holdings Inc. and guaranteed by Citigroup Inc. All payments due on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. None of Wells Fargo Securities, LLC ("Wells Fargo") or any of its affiliates will have any liability to the purchasers of the notes in the event Citigroup Global Markets Holdings Inc. defaults on its obligations under the notes and Citigroup Inc. defaults on its guarantee obligations. The notes are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency, nor are they obligations of, or guaranteed by, a bank.

(1) Citigroup Global Markets Holdings Inc. currently expects that the estimated value of the notes on the pricing date will be at least $903.50 per note, which will be less than the public offering price. The estimated value of the notes is based on Citigroup Global Markets Inc.'s ("CGMI") 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 any 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) CGMI, an affiliate of Citigroup Global Markets Holdings Inc., as the lead agent for the offering, expects to sell the notes to Wells Fargo, as agent. Wells Fargo will receive an underwriting discount and commission of up to 3.825% ($38.25) for each note it sells. Wells Fargo may pay selected dealers, which may include Wells Fargo Advisors ("WFA") (the trade name of the retail brokerage business of its affiliates, Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC), a fixed selling commission of 2.25% ($22.50) for each note they sell. In addition to the selling commission allowed to WFA, Wells Fargo may pay $0.75 per note of the underwriting discount and commission to WFA as a distribution expense fee for each note sold by WFA. The total underwriting discount and commission and proceeds to Citigroup Global Markets Holdings Inc. shown above give effect to the actual underwriting discount and commission provided for the sale of the notes. See "Supplemental Plan of Distribution" below and "Use of Proceeds and Hedging" in the accompanying prospectus for further information regarding how we have hedged our obligations under the notes.

(3) In respect of certain notes sold in this offering, CGMI may pay a fee of up to $3.00 per note to selected securities dealers in consideration for marketing and other services in connection with the distribution of the notes to other securities dealers.

Investor Considerations

The notes are not appropriate for all investors. The notes may be an appropriate investment for investors who:

·	seek exposure to any upside performance of the underlying without exposure to any decline in the underlying, by:

o	participating at the specified participation rate in the percentage increase, if any, from the starting value to the ending value, subject to the maximum return; and

o	providing for the repayment of the stated principal amount at maturity regardless of the performance of the underlying;

·	understand that if the ending value is less than or equal to the starting value, they will not receive any positive return on their investment in the notes;

·	are willing to forgo interest payments on the notes and dividends on securities included in the underlying; and

·	are willing to hold the notes to maturity.

The notes may not be an appropriate investment for investors who:

·	seek a liquid investment or are unable or unwilling to hold the notes to maturity;

·	seek certainty of receiving a positive return on their investment;

·	seek uncapped exposure to the upside performance of the underlying;

·	seek current income;

·	are unwilling to purchase notes with the estimated value set forth on the cover page;

·	are unwilling to accept the risk of exposure to the underlying;

·	seek exposure to the underlying but are unwilling to accept the risk/return trade-offs inherent in the maturity payment amount for the notes;

·	are unwilling to accept the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.; or

·	prefer the lower risk of fixed income investments with comparable maturities issued by companies with comparable credit ratings.

The considerations identified above are not exhaustive. Whether or not the notes are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the notes in light of your particular circumstances. You should also review carefully the "Summary Risk Factors" herein and the "Risk Factors" in the accompanying product supplement for risks related to an investment in the notes. For more information about the underlying, please see the information provided below.

Determining Maturity Payment Amount

On the maturity date, you will receive a cash payment per note (the maturity payment amount) calculated as follows:

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 (guaranteed by Citigroup Inc.), including the risk that we and Citigroup Inc. may default on our obligations under the notes, and are also subject to risks associated with the underlying. Accordingly, the notes are appropriate only for investors who are capable of understanding the complexities and risks of the notes. You should consult your own financial, tax and legal advisors as to the risks of an investment in the notes and the appropriateness 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" beginning on page PS-5 in the accompanying product supplement. You should also carefully read the risk factors included in the accompanying prospectus supplement and in the documents incorporated by reference in the accompanying prospectus, including Citigroup Inc.'s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which describe risks relating to the business of Citigroup Inc. more generally.

You May Not Receive Any Positive Return On Your Investment In The Notes.

You will receive a positive return on your investment in the notes only if the ending value is greater than the starting value. If the ending value is equal to or less than the starting value, you will receive only the stated principal amount for each note you hold at maturity. As the notes do not pay any interest, even if the ending value is greater than the starting value, there is no assurance that your total return at maturity on the notes will be as great as could have been achieved on conventional debt securities of ours or of another issuer with a similar credit rating of comparable maturity.

The Notes Do Not Pay Interest.

Unlike conventional debt securities, the notes do not pay interest or any other amounts prior to maturity. You should not invest in the notes if you seek current income during the term of the notes.

Your Potential Return On The Notes Is Limited.

Your potential total return on the notes at maturity is limited to the maximum return. Your return on the notes will not exceed the maximum return, even if the underlying appreciates by significantly more than the maximum return. If the underlying appreciates by more than the maximum return, the notes will underperform an alternative investment providing 1-to-1 exposure to the performance of the underlying. When lost dividends are taken into account, the notes may underperform an alternative investment providing 1-to-1 exposure to the performance of the underlying and a pass-through of dividends even if the underlying appreciates by less than the maximum return.

You Will Not Receive Dividends Or Have Any Other Rights With Respect To The Securities Included In The Underlying.

You will not receive any dividends with respect to the securities included in the underlying. This lost dividend yield may be significant over the term of the notes. The payment scenarios described in this pricing supplement do not show any effect of lost dividend yield over the term of the notes. In addition, you will not have voting rights or any other rights with respect to the securities included in the underlying.

Your Maturity Payment Amount Depends On The Value Of The Underlying On A Single Day.

Because your maturity payment amount depends on the value of the underlying solely on the calculation day, you are subject to the risk that the value of the underlying on that day may be lower, and possibly significantly lower, than on one or more other dates during the term of the notes. If you had invested in another instrument linked to the underlying that you could sell for full value at a time selected by you, or if the maturity payment amount were based on an average of values of the underlying, you might have achieved better returns.

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 The Percentage Change From The Starting Value to the Ending Value Is Less Than Or Not Sufficiently Greater Than Zero.

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. This potential loss in real value terms is significant given the term of the notes. You should carefully consider whether an investment that may not provide for any positive return on your investment, 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 Global Markets Holdings Inc. And Citigroup Inc.

If we default on our obligations under the notes and Citigroup Inc. defaults on its guarantee obligations, you may not receive anything owed to you under the notes.

The Notes Will Not Be Listed On Any 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. We have been advised that Wells Fargo currently intends to make a secondary market in relation to the notes. However, Wells Fargo may suspend or terminate making a market without notice, at any time and for any reason. If Wells Fargo suspends or terminates making a market, there may be no secondary market at all for the notes because it is likely that Wells Fargo 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 Global Markets Holdings Inc. and 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, Is Less Than The Public Offering Price.

The difference is attributable to certain costs associated with selling, structuring and hedging the notes that are included in the public offering price. These costs include (i) any selling concessions or other fees 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 and/or Wells Fargo or its 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 Wells Fargo's Determination Of The Secondary Market Rate With Respect To Us" 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 the underlying, the dividend yields on the securities included in the underlying and interest rates. 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 Wells Fargo's Determination Of The Secondary Market Rate With Respect To Us.

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. We expect that our internal funding rate is generally lower than Wells Fargo's determination of the secondary market rate with respect to us, which is the rate that we expect Wells Fargo will use in determining the value of the notes for purposes of any purchases of the notes from you in the secondary market. If the estimated value included in this pricing supplement were based on Wells Fargo's determination of the secondary market rate with respect to us, 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 an interest rate that is payable on the notes.

Because there is not an active market for traded instruments referencing our outstanding debt obligations, Wells Fargo may determine the secondary market rate with respect to us for purposes of any purchase of the notes from you in the secondary market based on the market price of traded instruments referencing the debt obligations of Citigroup Inc., our parent company and the guarantor of all payments due on the notes, but subject to adjustments that Wells Fargo may deem appropriate.

The Estimated Value Of The Notes Is Not An Indication Of The Price, If Any, At Which Any 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, we expect that any value of the notes determined for purposes of a secondary market transaction will be based on Wells Fargo's determination of the secondary market rate with respect to us, which will likely result in a lower value for the notes than if our internal funding rate were used. In addition, we expect that 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 may be reduced by 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 public offering 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 closing value of the underlying, the volatility of the closing value of the underlying, the dividend yields on the securities included in the underlying, interest rates generally, the time remaining to maturity and our and Citigroup Inc.'s creditworthiness, as reflected in our secondary market rate, among other factors described under "Risk Factors-General Risk Factors Relating To All Notes- The Value Of Your Notes Prior To Maturity Will Fluctuate Based On Many Unpredictable Factors" in the accompanying product supplement. Changes in the value of the underlying may not result in a comparable change in the value of your notes. You should understand that the value of your notes at any time prior to maturity may be significantly less than the public offering price.

We Have Been Advised That, Immediately Following Issuance, Any Secondary Market Bid Price Provided By Wells Fargo, And The Value That Will Be Indicated On Any Brokerage Account Statements Prepared By Wells Fargo 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.

The EURO STOXX 50^® Index Is Subject To Risks Associated With Non-U.S. Markets.

The stocks included in the EURO STOXX 50^® Index have been issued by companies outside of the U.S. Foreign equity securities involve risks associated with the securities markets in foreign countries, including risks of volatility in those markets, governmental intervention in those markets and cross-shareholdings in companies in certain countries. There is also generally less publicly available information about foreign companies than about U.S. companies that are subject to the reporting requirements of the Securities and Exchange Commission, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements different from those applicable to U.S. reporting companies. The prices of securities in foreign markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws. Moreover, the economies in such countries may differ unfavorably from the economy of the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

The Performance Of The EURO STOXX 50^® Index Will Not Be Adjusted For Changes In The Exchange Rate Between The Euro And The U.S. Dollar.

The EURO STOXX 50^® Index is composed of stocks traded in euro, the value of which may be subject to a high degree of fluctuation relative to the U.S. dollar. However, the performance of the EURO STOXX 50^® Index and the value of your notes will not be adjusted for exchange rate fluctuations. If the euro appreciates relative to the U.S. dollar over the term of the notes, the performance of the EURO STOXX 50^® Index as measured for purposes of the notes will be less than it would have been if it offered exposure to that appreciation in addition to the change in the prices of the underlying stocks.

Our Offering Of The Notes Is Not A Recommendation Of The Underlying.

The fact that we are offering the notes does not mean that we or Wells Fargo or its affiliates believe that investing in an instrument linked to the underlying is likely to achieve favorable returns. In fact, as we and Wells Fargo and its affiliates are each part of respective global financial institutions, our affiliates and affiliates of Wells Fargo may have positions (including short positions) in the underlying or in instruments related to the underlying, and may publish research or express opinions, that in each case are inconsistent with an investment linked to the underlying. These and other activities of our affiliates or of Wells Fargo or its affiliates may affect the closing value of the underlying in a way that negatively affects the value of and your return on the notes.

The Closing Value Of The Underlying May Be Adversely Affected By Our Or Our Affiliates', Or By Wells Fargo And Its Affiliates', Hedging And Other Trading Activities.

We expect to hedge our obligations under the notes through CGMI or other of our affiliates and/or Wells Fargo or its affiliates, who may take positions in the underlying or in financial instruments related to the underlying and may adjust such positions during the term of the notes. Our affiliates and Wells Fargo and its affiliates may also take positions in the underlying or in financial instruments related to the underlying on a regular basis (taking long or short positions or both), for their accounts, for other accounts under their management or to facilitate transactions on behalf of customers. These activities could affect the closing value of the underlying in a way that negatively affects the value of and your return on the notes. They could also result in substantial returns for us or our affiliates or Wells Fargo and its affiliates while the value of the notes declines.

We And Our Affiliates And Wells Fargo And Its Affiliates May Have Economic Interests That Are Adverse To Yours As A Result Of Our And Their Respective Business Activities.

Our affiliates and Wells Fargo and its affiliates engage in business activities with a wide range of companies. These activities include extending loans, making and facilitating investments, underwriting securities offerings and providing advisory services. These activities could involve or affect the underlying in a way that negatively affects the value of and your return on the notes. They could also result in substantial returns for us or our affiliates or Wells Fargo or its affiliates while the value of the notes declines. In addition, in the course of this business, we or our affiliates or Wells Fargo or its affiliates may acquire non-public information, which will not be disclosed to you.

The Calculation Agent, Which Is An Affiliate Of Ours, Will Make Important Determinations With Respect To The Notes.

If certain events occur during the term of the notes, such as market disruption events and other events with respect to the underlying, CGMI, as calculation agent, will be required to make discretionary judgments that could significantly affect your return on the notes. 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. See "Risk Factors-General Risk Factors Relating To All Notes-The Calculation Agent, Which Is An Affiliate Of Ours, Will Make Important Determinations With Respect To The Notes" in the accompanying product supplement.

Changes That Affect The Underlying May Affect The Value Of Your Notes.

The sponsor of the underlying may at any time make methodological changes or other changes in the manner in which it operates that could affect the value of the underlying. We are not affiliated with the underlying sponsor and, accordingly, we have no control over any changes the sponsor may make. Such changes could adversely affect the performance of the underlying and the value of and your return on the notes.

The Stated Maturity Date May Be Postponed If The Calculation Day Is Postponed.

The calculation day will be postponed for non-trading days and certain market disruption events. If such a postponement occurs, the maturity date will be postponed. For more information regarding adjustments to the calculation days and payment dates and the circumstances that may result in a market disruption event, see the relevant sections of the accompanying product supplement.

You Will Be Required To Recognize Taxable Income On The Notes Prior To Maturity.

If you are a U.S. holder of a note, you will be required to recognize taxable interest income in each year that you hold the note, even though you will not receive any payment in respect of the note prior to maturity (or earlier sale, exchange or retirement). In addition, any gain you recognize will be treated as ordinary interest income rather than capital gain. You should review the section of this pricing supplement entitled "United States Federal Tax Considerations."

Hypothetical Examples and Returns

The payout profile, return table and examples below illustrate how to determine the maturity payment amount on the notes, assuming the various hypothetical ending values indicated below. The examples are solely for illustrative purposes, do not show all possible outcomes and are not a prediction of what the actual maturity payment amount on the notes will be. The actual maturity payment amount will depend on the actual ending value.

The examples below are based on a hypothetical starting value of 100, rather than the actual starting value. For the actual starting value, see "Terms of the Notes" above. We have used this hypothetical value, rather than the actual value, to simplify the calculations and aid understanding of how the notes work. However, you should understand that the actual maturity payment amount on the notes will be calculated based on the actual starting value, and not the hypothetical value indicated below. The examples below assume that the maximum return will be set at the lowest value indicated in "Terms of the Notes" above. The actual maximum return will be determined on the pricing date.

Hypothetical Examples

Example 1-Upside Scenario A. The hypothetical ending value is 105 (a 5% increase from the starting value), which is greater than the starting value.

Maturity payment amount per note = $1,000 plus the lesser of:

(i) $1,000 × underlying return × participation rate and (ii) the maximum return

= $1,000 + the lesser of: (i) ($1,000 × 5% × 100%) and (ii) $500

= $1,000 + the lesser of: (i) $50 and (ii) $500

= $1,050

Because the underlying appreciated from the starting value to the hypothetical ending value, you would receive a total return at maturity equal to the upside performance of the underlying multiplied by the participation rate, which in this case is less than the maximum return.

Example 2-Upside Scenario B. The hypothetical ending value is 175 (a 75% increase from the starting value), which is greater than the starting value.

Maturity payment amount per note = $1,000 plus the lesser of:

(i) $1,000 × underlying return × participation rate and (ii) the maximum return

= $1,000 + the lesser of: (i) ($1,000 × 75% × 100%) and (ii) $500

= $1,000 + the lesser of: (i) $750 and (ii) $500

= $1,500

Because the underlying appreciated from the starting value to the hypothetical ending value and the upside performance of the underlying multiplied by the participation rate exceeds the maximum return, your total return at maturity would be limited to the maximum return in this case. In this scenario, an investment in the notes would underperform a hypothetical alternative investment providing 1-to-1 exposure to the appreciation of the underlying without a maximum return.

Example 3-Par Scenario. The hypothetical ending value is 90 (a 10% decrease from the starting value), which is less than the starting value.

Maturity payment amount per note = $1,000

Because the hypothetical ending value is less than the starting value, you would be repaid the stated principal amount of your notes at maturity but would not receive any positive return on your investment.

United States Federal Tax Considerations

In the opinion of our counsel, Davis Polk & Wardwell LLP, which is based on current market conditions, 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 product supplement called "United States Federal Tax Considerations-Tax Consequences to U.S. Holders-Notes Treated as Contingent Payment Debt Instruments," and the remaining discussion is based on this treatment.

If you are a U.S. Holder (as defined in the accompanying product supplement), you will be required to recognize interest income during the term of the notes 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 the amount and timing of which would produce a yield to maturity on the notes equal to the comparable yield. Assuming you hold the notes until their maturity, the amount of interest you include in income based on the comparable yield in the taxable year in which the notes mature will be adjusted upward or downward to reflect the difference, if any, between the actual and projected payment on the notes at maturity as determined under the projected payment schedule.

Upon the sale, exchange or retirement of the notes prior to maturity, 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 previously included in income on the notes. Any gain generally will be treated as ordinary income, and any loss generally will be treated as ordinary loss to the extent of prior interest inclusions on the note and as capital loss thereafter.

We have determined that the comparable yield for a note is a rate of %, compounded semi-annually, and that the projected payment schedule with respect to a note consists of a single payment of $ at maturity.

Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount that we will pay on the notes.

Non-U.S. Holders. Subject to the discussions below regarding Section 871(m) and in "United States Federal Tax Considerations-Tax Consequences to Non-U.S. Holders" and "-FATCA" in the accompanying product supplement, if you are a Non-U.S. Holder (as defined in the accompanying product supplement) of the notes, under current law you generally will not be subject to U.S. federal withholding or income tax in respect of any payment on or any amount received on the sale, exchange or retirement of 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 product supplement for a more detailed discussion of the rules applicable to Non-U.S. Holders of the notes.

As discussed under "United States Federal Tax Considerations-Tax Consequences to Non-U.S. Holders-Dividend Equivalents Under Section 871(m) of the Code" in the accompanying product supplement, Section 871(m) of the Internal Revenue Code of 1986, as amended, and Treasury regulations promulgated thereunder ("Section 871(m)") generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities ("Underlying Securities") or indices that include Underlying Securities. Section 871(m) generally applies to instruments that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations. However, the regulations, as modified by an Internal Revenue Service ("IRS") notice, exempt financial instruments issued prior to January 1, 2027 that do not have a "delta" of one. Based on the terms of the notes and representations provided by us as of the date of this preliminary pricing supplement, our counsel is of the opinion that the notes should not be treated as transactions that have a "delta" of one within the meaning of the regulations with respect to any Underlying Security and, therefore, should not be subject to withholding tax under Section 871(m). However, the final determination regarding the treatment of the notes under Section 871(m) will be made as of the pricing date for the notes, and it is possible that the notes will be subject to withholding under Section 871(m) based on the circumstances as of that date.

A determination that the notes are not subject to Section 871(m) is not binding on the IRS, and the IRS may disagree with this treatment. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances, including your other transactions. You should consult your tax adviser regarding the potential application of Section 871(m) to the notes.

If withholding tax applies to the notes, we will not be required to pay any additional amounts with respect to amounts withheld.

You should read the section entitled "United States Federal Tax Considerations" in the accompanying product 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 non-U.S. taxing jurisdiction.

Supplemental Plan of Distribution

Pursuant to the terms of the Amended and Restated Global Selling Agency Agreement, dated April 7, 2017, CGMI, acting as principal, will purchase the notes from Citigroup Global Markets Holdings Inc. CGMI, as the lead agent for the offering, expects to sell the notes to Wells Fargo, as agent. Wells Fargo will receive an underwriting discount and commission of up to 3.825% ($38.25) for each note it sells. Wells Fargo may pay selected dealers, which may include WFA, a fixed selling commission of 2.25% ($22.50) for each note they sell. In addition to the selling commission allowed to WFA, Wells Fargo may pay $0.75 per note of the underwriting discount and commission to WFA as a distribution expense fee for each note sold by WFA.

In addition, in respect of certain notes sold in this offering, CGMI may pay a fee of up to $3.00 per note to selected securities dealers in consideration for marketing and other services in connection with the distribution of the notes to other securities dealers.

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 or Citigroup Inc.'s 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. As of the date of this preliminary pricing supplement, it is uncertain what the estimated value of the notes will be on the pricing date because certain terms of the notes have not yet been fixed and because it is uncertain what the values of the inputs to CGMI's proprietary pricing models will be on the pricing date.

We have been advised that, for a period of approximately three months following issuance of the notes, the price, if any, at which Wells Fargo 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 Wells Fargo or its affiliates, 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 costs associated with selling, structuring and hedging the notes that are included in the public offering price of the notes. The amount of this temporary upward adjustment will decline to zero on a straight-line basis over the three-month temporary adjustment period. However, Wells Fargo is not obligated to buy the notes from investors at any time. See "Summary Risk Factors-The Notes Will Not Be Listed On Any Securities Exchange And You May Not Be Able To Sell Them Prior To Maturity."
