Market-Linked Notes Linked to the Nasdaq-100 Index<sup>®</sup> Due September 3, 2025

▪ The notes offered by this pricing supplement are unsecured debt
securities issued by Citigroup Global Markets Holdings Inc. and guaranteed by Citigroup Inc. Unlike conventional debt securities, the
notes do not pay interest. Instead, the notes offer the potential for a return at maturity based on the performance of the underlying
specified below from the initial underlying value to the final underlying value.

▪ If the underlying appreciates from the initial underlying value
to the final underlying value, you will receive a positive return at maturity equal to that appreciation *multiplied* by the upside
participation rate, subject to the maximum return at maturity specified below. However, if the underlying remains the same or depreciates
from the initial underlying value to the final underlying value, you will be repaid the stated principal amount of your notes at maturity
but will not receive any return on your investment. Even if the underlying appreciates from the initial underlying value to the final
underlying value, so that you do receive a positive return at maturity, there is no assurance that your total return at maturity on the
notes will compensate you for the effects of inflation or be as great as the yield you could have achieved on a conventional debt security
of ours of comparable maturity.

▪ In exchange for the possibility of a positive return at maturity
based on the performance of the underlying and repayment of the principal amount even if the underlying depreciates, investors in the
notes must be willing to forgo (i) any return on the notes in excess of the maximum return at maturity and (ii) dividends with respect
to the underlying. **If the underlying does not appreciate from the initial underlying value to the final underlying value, you will not receive any return on your investment in the notes.** 

▪ In order to obtain the modified exposure to the underlying that
the notes provide, investors 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 and Citigroup Inc. default on our obligations. **All payments on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.**

(1) Citigroup Global Markets Holdings Inc. currently expects that the estimated value of the notes on the pricing date will be at least $850.00 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) CGMI will receive an underwriting fee of up to $10.00 for each note sold in this offering. The total underwriting fee and proceeds to issuer in the table above give effect to the actual total 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.

(3) The per note proceeds to issuer indicated above represent the minimum per note proceeds to issuer for any note, assuming the maximum per note underwriting fee. As noted above, the underwriting fee is variable.

**Investing in the notes involves risks not associated with an investment in conventional debt securities. See "Summary Risk Factors" beginning on page PS-4.**

**Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the notes or determined that this pricing supplement and the accompanying product supplement, underlying supplement, prospectus supplement and prospectus are truthful or complete. Any representation to the contrary is a criminal offense.**

Hypothetical Examples

The examples below illustrate how to determine the payment at maturity on the notes, assuming the various hypothetical final underlying 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 payment at maturity on the notes will be. The actual payment at maturity will depend on the actual final underlying value.

The examples below are based on a hypothetical initial underlying value of 100.00 and do not reflect the actual initial underlying value. For the actual initial underlying value, see the cover page of this pricing supplement. 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 payment at maturity on the notes will be calculated based on the actual initial underlying value, and not this hypothetical value. For ease of analysis, figures below have been rounded. The examples below assume that the maximum return at maturity will be set at the lowest value indicated on the cover page of this pricing supplement. The actual maximum return at maturity will be determined on the pricing date.

**Example 1—Upside Scenario A.** The final underlying value is 105.00, resulting in a 5.00% underlying return. In this example, the final underlying value is **greater than** the initial underlying value.

Payment at maturity per note = $1,000 + the return amount, subject to the maximum return at maturity

= $1,000 + ($1,000 × the underlying return × the upside participation rate), subject to the maximum return at maturity

= $1,000 + ($1,000 × 5.00% × 100.00%), subject to the maximum return at maturity

= $1,000 + $50.00, subject to the maximum return at maturity

= $1,050.00

In this scenario, the underlying has appreciated from the initial underlying value to the final underlying value, and your total return at maturity would equal the underlying return *multiplied by* the upside participation rate.

**Example 2—Upside Scenario B.** The final underlying value is 150.00, resulting in a 50.00% underlying return. In this example, the final underlying value is **greater than** the initial underlying value.

Payment at maturity per note = $1,000 + the return amount, subject to the maximum return at maturity

= $1,000 + ($1,000 × the underlying return × the upside participation rate), subject to the maximum return at maturity

= $1,000 + ($1,000 × 50.00% × 100.00%), subject to the maximum return at maturity

= $1,000 + $500.00, subject to the maximum return at maturity

= $1,200.00

In this scenario, the underlying has appreciated from the initial underlying value to the final underlying value, but the underlying return *multiplied by* the upside participation rate would exceed the maximum return at maturity. As a result, your total return at maturity in this scenario would be limited to the maximum return at maturity, and 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 final underlying value is 90.00, resulting in a -10.00% underlying return.

Payment at maturity per note = $1,000

In this scenario, the underlying has depreciated from the initial underlying value to the final underlying value. As a result, your payment at maturity per note would equal the $1,000 stated principal amount per note and you would not receive any positive return on your investment.

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 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 advisors 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 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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **You may not receive any return on your investment in the notes.** You will receive a positive return on your investment in the
notes only if the underlying appreciates from the initial underlying value to the final underlying value. If the final underlying value
is equal to or less than the initial underlying value, you will receive only the stated principal amount of $1,000 for each note you hold
at maturity. As the notes do not pay any interest, even if the underlying appreciates from the initial underlying value to the final underlying
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 of comparable maturity.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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 underlying declines or does not appreciate sufficiently from the initial underlying value to the final underlying value.** 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 return on your investment, or may provide a return that is
lower than the return on alternative investments, is appropriate for you.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Your potential return on the notes is limited.** Your potential total return on the notes at maturity is limited to the maximum
return at maturity, even if the underlying appreciates by significantly more than the maximum return at maturity. If the underlying appreciates
by more than the maximum return at maturity, 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 even if the underlying appreciates by less than the maximum return at maturity.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **You will not receive dividends or have any other rights with respect to the underlying.** You will not receive any dividends
with respect to 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 such 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 underlying or the stocks included in the underlying.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **Your payment at maturity depends on the closing value of the underlying on a single day.** Because your payment at maturity depends
on the closing value of the underlying solely on the valuation date, you are subject to the risk that the closing 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 payment at maturity
were based on an average of closing values of the underlying, you might have achieved better returns.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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. 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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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 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) 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

<u>Citigroup Global Markets Holdings Inc.</u> <br>

(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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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 closing value of the underlying, the dividend yield
on 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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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 our secondary market rate, which
is the rate that CGMI 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 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 an interest rate that is payable on the notes.

Because there is not an active market for traded instruments referencing our outstanding debt obligations, CGMI determines our secondary market rate 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 CGMI makes in its sole discretion. As a result, our secondary market rate is not a market-determined measure of our creditworthiness, but rather reflects the market's perception of our parent company's creditworthiness as adjusted for discretionary factors such as CGMI's preferences with respect to purchasing the notes prior to maturity.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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
yield on 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 Relating to the Notes—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 closing 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 issue
price.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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 believe that investing in an instrument linked to the underlying 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 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 may affect the closing value of the underlying in a way that negatively affects the value
of and your return on the notes.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **The closing value of the underlying may be adversely affected by our or our affiliates' hedging and other trading activities.** We expect to hedge our obligations under the notes through CGMI or other of our 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 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 while the value of the notes declines.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **We and our affiliates may have economic interests that are adverse to yours as a result of our affiliates' business activities.** Our affiliates engage in business activities with a wide range of companies. These activities include extending loans, making and facilitating

<u>Citigroup Global Markets Holdings Inc.</u> <br>

investments, underwriting notes 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 while the value of the notes declines. In addition, in the course of this business, we or our affiliates may acquire non-public information, which will not be disclosed to you.

&nbsp;&nbsp;&nbsp;&nbsp;▪ **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

United States Federal Income 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. However, special rules may apply if the payment at maturity on the notes is treated as becoming fixed prior to maturity. See "United States Federal Tax Considerations—Tax Consequences to U.S. Holders—Notes Treated as Contingent Payment Debt Instruments" in the accompanying product supplement for a more detailed discussion of the special rules.

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, 2025 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

CGMI, an affiliate of Citigroup Global Markets Holdings Inc. 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 will be equal to the selling concession provided to selected dealers, as described in this paragraph. From this underwriting fee, CGMI will pay selected dealers not affiliated with CGMI a variable selling concession of up to $10.00 for each note they sell.

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.

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.

For a period of approximately three 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 three-month temporary adjustment period. However, CGMI 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."
