Principal-Protected Notes Based Upon the

European Union Euro Due September 27, 2009

• We will not make any payments on the notes prior to maturity.

• The notes will mature on September 27, 2009. You will receive at maturity, for each US$1,000 principal amount of notes you hold, an amount in cash equal to US$1,000 plus a currency return amount that may be positive or zero.

• The currency return amount will equal the product of (a) US$1,000 and (b) the absolute value of the positive or negative percentage change of the value of the European Union euro relative to the U.S. dollar, as measured by its exchange rate, from the date of this pricing supplement to the fifth business day before maturity (which we refer to as the valuation date). If the value of the European Union euro relative to the U.S. dollar on the valuation date is the same as the value of the European Union euro relative to the U.S. dollar on the pricing date, you will receive at maturity only the principal amount of the notes you then hold and your return on the notes will be zero. If the value of the European Union euro relative to the U.S. dollar on the valuation date is either greater than or less than the value of the European Union euro relative to the U.S. dollar on the pricing date, your return on the notes will be positive.

SUMMARY INFORMATION — Q&A

This summary includes questions and answers that highlight selected information from the accompanying prospectus and prospectus supplement and this pricing supplement to help you understand the Principal-Protected Notes Based Upon the European Union Euro Due September 27, 2009. You should carefully read the entire prospectus, prospectus supplement and pricing supplement to understand fully the terms of the notes, as well as the principal tax and other considerations that are important to you in making a decision about whether to invest in the notes. You should, in particular, carefully review the section entitled “Risk Factors Relating to the Notes,” which highlights a number of risks, to determine whether an investment in the notes is appropriate for you. All of the information set forth below is qualified in its entirety by the more detailed explanation set forth elsewhere in this pricing supplement and the accompanying prospectus supplement and prospectus.

What Are the Notes?

The notes are currency-linked securities issued by Citigroup Funding Inc. that have a maturity of approximately two years. The notes pay an amount at maturity that will depend on the absolute value of the positive or negative percentage change in the value of the European Union euro, relative to the U.S. dollar, from the date of this pricing supplement, which we refer to as the pricing date, to the fifth business day before maturity, which we refer to as the valuation date. If the percentage change of the value of the European Union euro relative to the U.S. dollar, as measured by its exchange rate, from the pricing date to the valuation date, is equal to zero, the payment you receive at maturity will equal only the amount of your initial investment in the notes. If the percentage change of the value of the European Union euro relative to the U.S. dollar, as measured by its exchange rate, from the pricing date to the valuation date is either negative or positive, the payment you receive at maturity will be greater than the amount of your initial investment in the notes.

The exchange rate used to measure the change in the value of the European Union euro is expressed as the amount of U.S. dollars that can be exchanged for one European Union euro. Thus, an increase in the EUR/USD exchange rate (that is, the European Union euro exchange rate) means that the value of the European Union euro has increased. For example, if the EUR/USD exchange rate has increased from 1.00 to 2.00, it means that the value of one European Union euro (as measured against the U.S. dollar) has increased from US$1.00 to US$2.00. Conversely, a decrease in the EUR/USD exchange rate means that the value of the European Union euro has decreased.

The notes mature on September 27, 2009 and do not provide for earlier redemption by you or by us. The notes are a series of unsecured senior debt securities issued by Citigroup Funding. Any payments due on the notes are fully and unconditionally guaranteed by Citigroup Inc., Citigroup Funding’s parent company. The notes will rank equally with all other unsecured and unsubordinated debt of Citigroup Funding, and, as a result of the guarantee, any payments due under the notes will rank equally with all other unsecured and unsubordinated debt of Citigroup.

You may transfer the notes only in minimum denominations and integral multiples of US$1,000. You will not have the right to receive physical certificates evidencing your ownership except under limited circumstances. Instead, we will issue the notes in the form of a global certificate, which will be held by the Depository Trust Company or its nominee. Direct and indirect participants in DTC will record beneficial ownership of the notes by individual investors. Accountholders in the Euroclear or Clearstream clearance systems may hold beneficial interests in the notes through the accounts that each of these systems maintains as a participant in DTC. You should refer to “Description of the Notes—Book-Entry System” in the accompanying prospectus supplement and the section “Description of Debt Securities—Book-Entry Procedures and Settlement” in the accompanying prospectus for further information.

What Does “Principal Protected” Mean?

“Principal Protected” means that your principal investment in the notes is not at risk if the notes are held until maturity regardless of the performance of the European Union euro relative to the U.S. dollar over the term

PS-2

of the notes. However, because the notes are not principal-protected prior to maturity, you may receive less than your initial investment if you sell your notes in the secondary market prior to maturity. See “Risk Factors Relating to the Notes” for further information.

Will I Receive Interest on the Notes?

No. We will not make any periodic payments of interest on the notes.

What Will I Receive at Maturity of the Notes?

The notes will mature on September 27, 2009. You will receive at maturity, for each US$1,000 principal amount of notes you hold, an amount in cash equal to US$1,000 plus a currency return amount, which may be positive or zero.

How is the Currency Return Amount Defined?

The currency return amount will be based on the absolute currency return percentage.

The absolute currency return percentage will equal the percentage change in the value of the European Union euro from the pricing date to the valuation date, without regard to whether the change was positive or negative, expressed as the following fraction:

Ending Exchange Rate – Starting Exchange Rate

Starting Exchange Rate

provided that if the above calculation results in a negative number, the absolute currency return percentage will equal the product of (i) such negative number and (ii) –1. Thus, the absolute currency return percentage will always be positive or zero.

The starting exchange rate equals the EUR/USD exchange rate on the pricing date which was 1.4093.

The ending exchange rate will equal the EUR/USD exchange rate on the valuation date.

The EUR/USD exchange rate will equal the European Union euro/U.S. dollar exchange rate in the global spot foreign exchange market, expressed as the amount of U.S dollars per one European Union euro, as reported by Reuters on Page “1FED,” or any substitute page, at 10:00 a.m. (New York City time) on any relevant date.

The currency return amount will equal the product of (a) $1,000 and (b) the absolute currency return percentage, provided that the currency return amount will not be less than zero.

If the EUR/USD exchange rate is not so reported on Reuters page “1FED” or any substitute page thereto, then the EUR/USD exchange rate will equal the noon buying rate in New York for cable transfers in foreign currencies as announced by the Federal Reserve Bank of New York for customs purposes (the “Noon Buying Rate”) on the relevant date. If the Noon Buying Rate is not announced on that date, then the EUR/USD exchange rate will be calculated on the basis of the arithmetic mean of the applicable spot quotations received by the calculation agent at the relevant time for the purchase or sale for deposits in European Union euros by the London offices of three leading banks engaged in the interbank market (selected by the calculation agent after consultation with Citigroup Funding) (the “Reference Banks”). If fewer than three Reference Banks provide those spot quotations, then the EUR/USD exchange rate will be calculated on the basis of the arithmetic mean of the applicable spot quotations received by the calculation agent from two leading commercial banks in New York (selected by the calculation agent after consultation with Citigroup Funding), for the purchase or sale for deposits in European Union euros. If a spot quotation is available from only one bank, then the calculation agent, in its sole discretion, will determine if the use of such quotation is reasonable. If no spot quotation is available, or if the use of the available quotation is not deemed reasonable, then the EUR/USD exchange rate will be the rate the calculation agent, in its sole discretion, determines to be fair and reasonable under the circumstances.

PS-3

For more specific information about the “currency return amount,” the “absolute currency return percentage” and the determination of the EUR/USD exchange rate, please see “Description of the Notes—Currency Return Amount” in this pricing supplement.

Where Can I Find Examples of Hypothetical Maturity Payments?

For examples of hypothetical maturity payments, see “Description of the Notes—Hypothetical Maturity Payment Examples” in this pricing supplement.

What Will I Receive if I Sell the Notes Prior to Maturity?

If you choose to sell your notes before maturity, you are not guaranteed to receive the full principal amount of the notes you sell. You should refer to the sections “Risk Factors Relating to the Notes—The Price at Which You Will Be Able to Sell Your Notes Prior to Maturity Will Depend on a Number of Factors and May Be Substantially Less Than the Amount You Originally Invest” and “—You May Not Be Able to Sell Your Notes if an Active Trading Market for the Notes Does Not Develop” in this pricing supplement for further information. You will receive at least the full amount of the principal amount of your notes if you hold the notes at maturity.

How Has the European Union Euro Performed Historically?

We have provided a graph showing the daily values of the European Union euro exchange rate, as reported on Bloomberg, from January 1, 2002 to September 24, 2007, and a table showing the high and low values of the European Union euro exchange rate for each quarter since the first quarter of 2002. You can find this graph and table in the section “The European Union Euro and the EUR/USD Exchange Rate—Historical Data on the EUR/USD Exchange Rate” in this pricing supplement. We have provided this historical information to help you evaluate the behavior of the value of the European Union euro in recent years. However, past performance is not indicative of how the European Union euro will perform in the future.

Can You Tell Me More About the Effect of Citigroup Funding’s Hedging Activity?

We expect to hedge our obligations under the notes through one or more of our affiliates. This hedging activity will likely involve trading in the European Union euro or in other instruments, such as options, swaps or futures, based on the EUR/USD exchange rate or the European Union euro. The costs of maintaining or adjusting this hedging activity could affect the price at which our affiliate Citigroup Global Markets may be willing to purchase your notes in the secondary market. Moreover, this hedging activity may result in us or our affiliates receiving a profit, even if the market value of the notes declines. You should refer to “Risk Factors Relating to the Notes — The Price at Which You Will Be Able to Sell Your Notes Prior to Maturity Will Depend on a Number of Factors and May Be Substantially Less Than the Amount You Originally Invest” in this pricing supplement, “Risk Factors — Citigroup Funding’s Hedging Activity Could Result in a Conflict of Interest” in the accompanying prospectus supplement and “Use of Proceeds and Hedging” in the accompanying prospectus.

Does ERISA Impose Any Limitations on Purchases of the Notes?

Employee benefit plans and other entities the assets of which are subject to the fiduciary responsibility provisions of the Employee Retirement Income Security Act of 1974, as amended, Section 4975 of the Internal Revenue Code of 1986, as amended, or substantially similar federal, state or local laws, including individual retirement accounts, (which we call “Plans”) will be permitted to purchase and hold the notes, provided that each such Plan shall by its purchase be deemed to represent and warrant either that (A)(i) none of Citigroup Global Markets Inc., its affiliates or any employee thereof is a Plan fiduciary that has or exercises any discretionary authority or control with respect to the Plan’s assets used to purchase the notes or renders investment advice with respect to those assets and (ii) the Plan is paying no more than adequate consideration for the notes or (B) its acquisition and holding of the notes is not prohibited by any such provisions or laws or is exempt from any such prohibition. However, individual retirement accounts, individual retirement annuities and Keogh plans, as well as employee benefit plans that permit participants to direct the investment of their accounts, will not be permitted to

PS-4

purchase or hold the notes if the account, plan or annuity is for the benefit of an employee of Citigroup Global Markets Inc. or a family member and the employee receives any compensation (such as, for example, an addition to bonus) based on the purchase of notes by the account, plan or annuity. Please refer to the section “ERISA Matters” in this pricing supplement for further information.

What Are the U.S. Federal Income Tax Consequences of Investing in the Notes?

Because the notes are contingent payment debt obligations of Citigroup Funding, U.S. Holders of a note will be required to include original issue discount (“OID”) for U.S. federal income tax purposes in gross income on a constant yield basis over the term of the note, which yield will be assumed to be 5.02% per year, compounded semi-annually. This tax OID (computed at the assumed comparable yield) will be includible in a U.S. Holder’s gross income (as ordinary income) over the term of the note (although holders will receive no payments on the notes prior to maturity). The assumed comparable yield is based on a rate at which Citigroup Funding would issue a similar debt obligation with no contingent payments. The amount of the tax OID is calculated based in part on an assumed amount payable at maturity. This assumed amount is neither a prediction nor guarantee of the actual yield of, or payment to be made in respect of, a note. If the amount we actually pay at maturity is, in fact, less than this assumed amount, then a U.S. Holder will have recognized taxable income in periods prior to maturity that exceeds that holder’s economic income from holding the note during such periods (with an offsetting ordinary loss). If the amount we actually pay at maturity is, in fact, higher than this assumed amount, then a U.S. Holder will be required to include such additional amount as ordinary income. If a U.S. Holder disposes of the note prior to maturity, the U.S. Holder will be required to treat any gain recognized upon the disposition of the note as ordinary income (rather than capital gain). You should refer to “Certain United States Federal Income Tax Considerations” in this pricing supplement for more information.

Will the Notes Be Listed on a Stock Exchange?

No. The notes will not be listed on any exchange.

Can You Tell Me More About Citigroup and Citigroup Funding?

Citigroup is a diversified global financial services holding company whose businesses provide a broad range of financial services to consumer and corporate customers. Citigroup Funding is a wholly-owned subsidiary of Citigroup whose business activities consist primarily of providing funds to Citigroup and its subsidiaries for general corporate purposes.

What Is the Role of Citigroup Funding’s and Citigroup’s Affiliates, Citigroup Global Markets Inc. and Citigroup Financial Products Inc.?

Our affiliate, Citigroup Global Markets Inc. is the agent for the offering and sale of the notes. After the initial offering, Citigroup Global Markets Inc. and/or other of our affiliated dealers currently intend, but are not obligated, to buy and sell the notes to create a secondary market for holders of the notes, and may engage in other activities described in the section “Plan of Distribution” in this pricing supplement, the accompanying prospectus supplement and prospectus. However, neither Citigroup Global Markets Inc. nor any of these affiliates will be obligated to engage in any market-making activities, or continue those activities once it has started them.

Our affiliate, Citigroup Financial Products Inc., will act as calculation agent for the notes. Potential conflicts of interest may exist between Citigroup Financial Products Inc. as calculation agent and you as a holder of the notes.

Are There Any Risks Associated With My Investment?

Yes, the notes are subject to a number of risks. Please refer to the section “Risk Factors Relating to the Notes” in this pricing supplement.

PS-5

RISK FACTORS RELATING TO THE NOTES

An investment in the notes entails significant risks not associated with similar investments in a conventional debt security, including, among other things, fluctuations in the value of the European Union euro relative to the U.S. dollar, and other events that are difficult to predict and beyond our control.

The Return on Your Notes May Be Zero

The amount of the maturity payment will depend on the absolute currency return percentage, which is equal to the absolute value of the positive or negative percentage change of the value of the European Union euro relative to the U.S. dollar from the pricing date to the valuation date. If the value of the European Union euro relative to the U.S. dollar on the valuation date is equal to the value of the European Union euro relative to the U.S. dollar on the pricing date, the payment you receive at maturity will be limited to the amount of your initial investment in the notes. This will be true even if the value of the European Union euro has increased or declined relative to the U.S. dollar at one or more times during the term of the notes, but the value of the European Union euro on the pricing date is equal to the value of the European Union euro on the valuation date.

No Principal Protection Unless You Hold the Notes to Maturity

You will be entitled to receive at least the full principal amount of your notes only if you hold the notes to maturity. The market value of the notes may fluctuate and, because the notes are not principal-protected prior to maturity, you may receive less than your initial investment if you sell your notes in the secondary market prior to maturity.

The Yield on the Notes May Be Lower Than the Yield On a Standard Debt Security of Comparable Maturity

The notes do not pay any interest. As a result, if the absolute currency return percentage is less than 5.02%, the effective yield on your notes will be less than that which would be payable on a conventional fixed-rate, non-callable debt security of Citigroup Funding of comparable maturity.

The Values of the European Union Euro and the U.S. Dollar Are Affected by Many Complex Factors

The value of any currency, including the European Union euro and the U.S. dollar, may be affected by complex political and economic factors. The value of the European Union euro relative to the U.S. dollar, as measured by the EUR/USD exchange rate, is at any moment a result of the supply and demand for the European Union euro and U.S. dollar, and changes in the EUR/USD exchange rate may result over time from the interaction of many factors directly or indirectly affecting economic and political conditions in the European Union and the United States, as well as economic and political developments in other countries. Of particular importance are the relative rates of inflation, interest rate levels, the balance of payments and the extent of governmental surpluses or deficits in the European Union and the United States, all of which are in turn sensitive to the monetary, fiscal and trade policies pursued by those and other countries important to international trade and finance.

Foreign exchange rates can either be fixed by sovereign governments or floating. Exchange rates of many nations are permitted to fluctuate in value relative to other currencies. However, governments sometimes do not allow their currencies to float freely in response to economic forces. Governments, including those of the European Union and the United States, use a variety of techniques, such as intervention by their central bank or imposition of regulatory controls or taxes, to affect the exchange rates of their respective currencies. They may also issue a new currency to replace an existing currency or alter the exchange rate or relative exchange rate characteristics by devaluation or revaluation of a currency. Thus, a special risk in purchasing the notes is that their liquidity, trading value and amounts payable could be affected by the actions of sovereign governments that could change or interfere with theretofore freely determined currency valuations, fluctuations in response to other market forces and the movement of currencies across borders. There will be no adjustment or change in the terms

PS-6

of the notes in the event that the EUR/USD exchange rate should become fixed, or in the event of any devaluation or revaluation or imposition of exchange or other regulatory controls or taxes, or in the event of the issuance of a replacement currency or in the event of other developments affecting the European Union euro or the U.S. dollar specifically, or any other currency.

The Price at Which You Will Be Able to Sell Your Notes Prior to Maturity Will Depend on a Number of Factors and May Be Substantially Less Than the Amount You Originally Invest

We believe that the value of the notes in the secondary market will be affected by supply of and demand for the notes, the value of the European Union euro relative to the U.S. dollar, as measured by the EUR/USD exchange rate, and a number of other factors. Some of these factors are interrelated in complex ways. As a result, the effect of any one factor may be offset or magnified by the effect of another factor. The following paragraphs describe what we expect to be the impact on the market value of the notes of a change in a specific factor, assuming all other conditions remain constant.

The European Union Euro Exchange Rate. We expect that the market value of the notes at any given time will likely depend substantially on the percentage change, if any, in the value of the European Union euro relative to the U.S. dollar from its starting value (as measured by a corresponding change in the EUR/USD exchange rate from its starting value), without regard to whether the change was positive or negative. For example, as a positive percentage change in the EUR/USD exchange rate increases, or as a negative percentage change in the EUR/USD exchange rate becomes more negative, the market value of the notes may increase because of expectations that the maturity payment on the notes will increase. Conversely, as a positive percentage change in the EUR/USD exchange rate decreases, or as a negative percentage change in the EUR/USD exchange rate becomes less negative, the market value of the notes may decrease because of expectations that the maturity payment on the notes will decrease.

The value of the European Union euro relative to the U.S. dollar will be influenced by complex and interrelated political, economic, financial and other factors that can affect the currency markets on which the European Union euro and the U.S. dollar are traded. Some of these factors are described in more detail in “—The Values of the European Union Euro and the U.S. Dollar Are Affected by Many Complex Factors” above.

Volatility of the European Union Euro. Volatility is the term used to describe the size and frequency of market fluctuations. If the expected volatility of the value of the European Union euro relative to the U.S. dollar changes, as measured by the EUR/USD exchange rate, the market value of the notes may change.

Interest Rates. We expect that the market value of the notes will be affected by changes in U.S. interest rates. In general, if U.S. interest rates increase, the market value of the notes may decrease, and if U.S. interest rates decrease, the market value of the notes may increase. In addition, increases in U.S. interest rates relative to interest rates in the European Union may decrease the future value of European Union euro relative to the U.S. dollar. Conversely, decreases in U.S. interest rates relative to interest rates in the European Union may increase the future value of the European union euro relative to the U.S. dollar.

Decreases in interest rates in the European Union relative to U.S. interest rates may decrease the future values of the European Union euro relative to the U.S. dollar, and increases in interest rates in the European Union relative to U.S. interest rates may increase the future values of the European Union euro relative to the U.S. dollar. Interest rates may also affect the economy of the European Union or of the United States and, in turn, the value of the European Union euro relative to the U.S. dollar, as measured by the EUR/USD Exchange Rate.

Time Premium or Discount. As a result of a “time premium or discount,” the notes may trade at a value above or below that which would be expected based on the level of interest rates and the value of the European Union euro relative to the U.S. dollar the longer the time remaining to maturity. A “time premium or discount” results from expectations concerning the value of the European Union euro relative to the U.S. dollar during the period prior to the maturity of the notes. However, as the time remaining to maturity decreases, this time premium or discount may diminish, thereby increasing or decreasing the market value of the notes.

PS-7

Hedging Activities. Hedging activities related to the notes by one or more of our affiliates will likely involve trading in the European Union euro or in the other instruments, such as options, swaps or futures, based upon the EUR/USD exchange rate or the European Union euro. This hedging activity could affect the market value of the notes. It is possible that we or our affiliates may profit from our hedging activity, even if the market value of the notes declines. Profit or loss from this hedging activity could affect the price at which Citigroup Funding’s affiliate Citigroup Global Markets may be willing to purchase your notes in the secondary market.

Citigroup Funding and Citigroup Inc.’s Credit Ratings, Financial Condition and Results. Actual or anticipated changes in our financial condition or results or the credit ratings, financial condition or results of Citigroup Inc. may affect the market value of the notes. The notes are subject to the credit risk of Citigroup Inc., the guarantor of any payments due on the notes.

We want you to understand that the impact of one of the factors specified above may offset some or all of any change in the market value of the notes attributable to another factor.

The Historical Performance of the European Union Euro Is Not an Indication of the Future Performance of the European Union Euro

The historical performance of the European Union euro relative to the U.S. dollar, as measured by the EUR/USD exchange rate, which is included in this pricing supplement, should not be taken as an indication of the future performance of the European Union euro during the term of the notes. Changes in the value of the European Union euro relative to the U.S. dollar will affect the trading price of the notes, but it is impossible to predict whether the value of the European Union euro relative to the U.S. dollar will rise, fall or remain the same.

Even Though the European Union Euro Trades Around-the-Clock, Your Notes Will Not

While the interbank market in foreign currencies is a global, around-the-clock market, your notes will not trade around the clock. Significant price and rate movements may take place in the underlying foreign exchange markets during hours when the notes are not traded that may be reflected when trading hours for the notes commence.

There is no systematic reporting of last-sale information for foreign currencies. Reasonably current bid and offer information is available in certain brokers’ offices, in bank foreign currency trading offices and to others who wish to subscribe to this information, but this information will not necessarily be reflected in the value of the European Union euro relative to the U.S. dollar used to calculate the maturity payment on your notes. There is no regulatory requirement that those quotations be firm or revised on a timely basis. The absence of last-sale information and the limited availability of quotations to individual investors may make it difficult for many investors to obtain timely, accurate data about the state of the underlying foreign exchange markets.

You May Not Be Able to Sell Your Notes if an Active Trading Market for the Notes Does Not Develop

The notes have not been and will not be listed on any exchange. There is currently no secondary market for the notes. Citigroup Global Markets and/or other of Citigroup Funding’s affiliated dealers currently intend, but are not obligated, to make a market in the notes. Even if a secondary market does develop, it may not be liquid and may not continue for the term of the notes. If the secondary market for the notes is limited, there may be few buyers should you choose to sell your notes prior to maturity and this may reduce the price you receive.

Citigroup Financial Products Inc. Is the Calculation Agent, Which Could Result in a Conflict of Interest

Citigroup Financial Products Inc., which is acting as the calculation agent for the notes, is an affiliate of ours. As a result, Citigroup Financial Products Inc.’s duties as calculation agent, including with respect to certain determinations and judgments that the calculation agent must make in determining amounts due to you, may conflict with its interest as an affiliate of ours.

DESCRIPTION OF THE NOTES

The description in this pricing supplement of the particular terms of the notes supplements, and to the extent inconsistent therewith replaces, the descriptions of the general terms and provisions of the debt securities set forth in the accompanying prospectus and prospectus supplement.

General

The Principal-Protected Notes Based Upon the European Union Euro Due September 27, 2009 (the “Notes”) are currency-linked securities issued by Citigroup Funding Inc. that have a maturity of approximately two years. The Notes pay an amount at maturity that will depend on the absolute value of the positive or negative percentage change in the value of the European Union euro, relative to the U.S. dollar, over the term of the Notes. If the percentage change of the value of the European Union euro relative to the U.S. dollar, as measured by its exchange rate, from the Pricing Date to the Valuation Date, is equal to zero, the payment you receive at maturity will equal the amount of your initial investment in the Notes. If the percentage change of the value of the European Union euro relative to the U.S. dollar, as measured by its exchange rate, from the Pricing Date to the Valuation Date is either negative or positive, the payment you receive at maturity will be greater than the amount of your initial investment in the Notes.

The exchange rate used to measure the performance of the European Union euro is expressed as the amount of U.S. dollars that can be exchanged for one European Union euro. Thus, an increase in the EUR/USD Exchange Rate means that the value of the European Union euro has increased. For example, if the EUR/USD Exchange Rate has increased from 1.00 to 2.00, it means the value of one European Union euro (as measured against the U.S. dollar) has increased from US$1.00 to US$2.00. Conversely, a decrease in the EUR/USD Exchange Rate means that the value of the European Union euro has decreased.

The Notes are a series of debt securities issued by Citigroup Funding under the senior debt indenture described in the accompanying prospectus supplement and prospectus and any payments due under the Notes are fully and unconditionally guaranteed by Citigroup Inc. The aggregate principal amount of Notes issued will be US$25,000,000 (25,000 Notes). The Notes will mature on September 27, 2009, will constitute part of the senior debt of Citigroup Funding, and will rank equally with all other unsecured and unsubordinated debt of Citigroup Funding. As a result of the Citigroup Inc. guarantee, any payments due under the Notes will rank equally with all other unsecured and unsubordinated debt of Citigroup Inc. The Notes will be issued only in fully registered form and in denominations of US$1,000 per Note and integral multiples thereof.

Reference is made to the accompanying prospectus supplement and prospectus for a detailed summary of additional provisions of the Notes and of the senior debt indenture under which the Notes will be issued.

Interest

We will not make any periodic payments of interest on the Notes.

Payment at Maturity

The Notes will mature on September 27, 2009. You will receive at maturity, for each US$1,000 principal amount of Notes you hold, an amount in cash equal to US$1,000 plus a Currency Return Amount, which may be positive or zero.

Currency Return Amount

The Currency Return Amount will be based on the Absolute Currency Return Percentage.

PS-9

The Absolute Currency Return Percentage will equal the percentage change in the value of the European Union euro from the Pricing Date to the Valuation Date, without regard to whether the change was positive or negative, expressed as the following fraction:

Ending Exchange Rate – Starting Exchange Rate

Starting Exchange Rate

provided that if the above calculation results in a negative number, the Absolute Currency Return Percentage will equal the product of (i) such negative number and (ii) –1. Thus, the Absolute Currency Return Percentage will always be positive or zero.

The Starting Exchange Rate for the European Union euro equals the EUR/USD Exchange Rate on the Pricing Date which was 1.4093.

The Ending Exchange Rate for the European Union euro will equal the EUR/USD Exchange Rate on the Valuation Date.

The Pricing Date means September 24, 2007 the date of this pricing supplement and the day on which the Notes were priced for initial sale to the public.

The Valuation Date will be the fifth Business Day before maturity.

The EUR/USD Exchange Rate will equal the European Union euro/U.S. dollar exchange rate in the global spot foreign exchange market, expressed as the amount of U.S. dollars per one European Union euro, as reported by Reuters on Page “1FED,” or any substitute page, at 10:00 a.m. (New York City time) on any relevant date.

The Currency Return Amount will equal the product of (a) $1,000 and (b) the Absolute Currency Return Percentage, provided that the Currency Return Amount will not be less than zero.

If the EUR/USD Exchange Rate is not so reported on Reuters page “1FED,” or any substitute page thereto, then the EUR/USD Exchange Rate will equal the noon buying rate in New York for cable transfers in foreign currencies as announced by the Federal Reserve Bank of New York for customs purposes (the “Noon Buying Rate”) on the relevant date. If the Noon Buying Rate is not announced on that date, then the EUR/USD Exchange Rate will be calculated on the basis of the arithmetic mean of the applicable spot quotations received by the calculation agent at the relevant time for the purchase or sale for deposits in the European Union euros by the London offices of three leading banks engaged in the interbank market (selected by the calculation agent after consultation with Citigroup Funding) (the “Reference Banks”). If fewer than three Reference Banks provide those spot quotations, then the EUR/USD Exchange Rate will be calculated on the basis of the arithmetic mean of the applicable spot quotations received by the calculation agent from two leading commercial banks in New York (selected by the calculation agent after consultation with Citigroup Funding), for the purchase or sale for deposits in the European Union euros. If a spot quotation is available from only one bank, then the calculation agent, in its sole discretion, will determine if the use of such quotation is reasonable. If no spot quotation is available, or if the use of the available quotation is not deemed reasonable, then the EUR/USD Exchange Rate will be the rate the calculation agent, in its sole discretion, determines to be fair and reasonable under the circumstances.

“Business Day” means any day that (1) is not a Saturday, a Sunday or a day on which the securities exchanges or banking institutions or trust companies in the City of New York or in London, England are authorized or obligated by law or executive order to close and (2) is a day on which the Trans-European Automated Real-Time Gross Settlement Express Transfer System is open.

Hypothetical Maturity Payment Examples

The examples below show the hypothetical maturity payments to be made on an investment of US$1,000 principal amount of Notes based on various Ending Exchange Rates of the European Union euro. The following examples of hypothetical maturity payment calculations are based on the following assumptions:

• Pricing Date: September 19, 2007

• Issue Date: September 27, 2007

• Principal amount: US$1,000 per Note

• Starting Exchange Rate of the EUR/USD Exchange Rate: 1.3650

• Maturity Date: September 27, 2009

• The Notes are purchased on the Issue Date and are held through the Maturity Date.

The following examples are for purposes of illustration only and would provide different results if different assumptions were applied. The actual maturity payment will depend on the actual Currency Return Amount which, in turn, will depend on the actual Starting Exchange Rate and Ending Exchange Rate of the European Union euro and the calculation formula of the Currency Return Amount.

Redemption at the Option of the Holder; Defeasance

The Notes are not subject to redemption at the option of any holder prior to maturity and are not subject to the defeasance provisions described in the accompanying prospectus under “Description of Debt Securities—Defeasance.”

Default Interest Rate

In case of default in payment at maturity of the Notes, the Notes shall bear interest, payable upon demand of the beneficial owners of the Notes in accordance with the terms of the Notes, from and after the maturity date through the date when payment of the unpaid amount has been made or duly provided for, at the rate of 5.125% per annum on the unpaid amount due. If default interest is required to be calculated for a period of less than one year, it will be calculated on the basis of the actual number of days elapsed and a 360-day year consisting of twelve 30-day months.

Paying Agent and Trustee

Citibank, N.A. will serve as paying agent and registrar for the Notes and will also hold the global security representing the Notes as custodian for DTC. The Bank of New York, as successor trustee under an indenture dated as of June 1, 2005, will serve as trustee for the Notes.

Calculation Agent

The calculation agent for the Notes will be Citigroup Financial Products Inc. All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will, in the absence of manifest error, be conclusive for all purposes and binding on Citigroup Funding, Citigroup Inc. and the holders of the Notes. Because the calculation agent is an affiliate of Citigroup Funding and Citigroup Inc., potential conflicts of interest may exist between the calculation agent and the holders of the Notes, including with respect to certain determinations and judgments that the calculation agent must make in determining amounts due to holders of the Notes. Citigroup Financial Products Inc. is obligated to carry out its duties and functions as calculation agent in good faith and using its reasonable judgment.

THE EUROPEAN UNION EURO AND THE EUR/USD EXCHANGE RATE

General

The Notes pay an amount at maturity that will depend on the absolute value of the positive or negative percentage change in the value of the European Union euro relative to the U.S. dollar from the Pricing Date to the Valuation Date.

The EUR/USD Exchange Rate is the foreign exchange spot rate that measures the relative value of the U.S. dollar and the European Union euro. The EUR/USD Exchange Rate is expressed as the amount of U.S. dollars that can be exchanged for one European Union euro. Thus, an increase in the value of the European Union euro will cause an increase in the EUR/USD Exchange Rate, while a decrease in the value of the European Union euro will cause a decrease in the EUR/USD.

The European Union euro is the official currency of 13 European Union countries: Belgium, Germany, Greece, Spain, France, Ireland, Italy, Luxembourg, the Netherlands, Austria, Portugal, Slovenia and Finland.

We have obtained all information in this pricing supplement relating to the European Union euro and the EUR/USD Exchange Rate from public sources, without independent verification. Currently, the EUR/USD Exchange Rate is published in The Wall Street Journal and other financial publications of general circulation. However, for purposes of calculating amounts due to holders of the Notes, the value of the European Union euro relative to the U.S. dollar, as measured by the EUR/USD Exchange Rate, will be determined as described in “Description of the Notes—Currency Return Amount” above.

Historical Data on the Exchange Rates

The following table sets forth, for each of the quarterly periods indicated, the high and low values of the EUR/USD Exchange Rate, as reported by Bloomberg. The historical data on the EUR/USD Exchange Rate are not indicative of the future performance of the European Union euro or what the value of the Notes may be. Any historical upward or downward trend in the EUR/USD Exchange Rate during any period set forth below is not an indication that the value of the European Union euro relative to the U.S. dollar is more or less likely to increase or decrease at any time over the term of the Notes.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations that may be relevant to a beneficial owner of a Note that is a citizen or resident of the United States or a domestic corporation or otherwise subject to U.S. federal income tax on a net income basis in respect of a Note (a “U.S. Holder”). All references to “holders” (including U.S. Holders) are to beneficial owners of the Notes. This summary is based on U.S. federal income tax laws, regulations, rulings and decisions in effect as of the date of this pricing supplement, all of which are subject to change at any time (possibly with retroactive effect).

This summary addresses the U.S. federal income tax consequences to U.S. Holders who are initial holders of the Notes and who will hold the Notes as capital assets. This summary does not address all aspects of U.S. federal income taxation that may be relevant to a particular holder in light of its individual investment circumstances or to certain types of holders subject to special treatment under the U.S. federal income tax laws, such as dealers in securities or foreign currency, financial institutions, insurance companies, tax-exempt organizations or taxpayers holding the Notes as part of a “straddle,” hedge,” “conversion transaction,” “synthetic security” or other integrated investment, and persons whose functional currency is not the U.S. dollar. Moreover, the effect of any applicable state, local or foreign tax laws is not discussed.

Investors should consult their own tax advisors in determining the tax consequences to them of holding the Notes, including the application to their particular situation of the U.S. federal income tax considerations discussed below.

Tax Characterization of the Notes

Citigroup Funding will treat each Note for U.S. federal income tax purposes as a single debt instrument issued by Citigroup Funding that is subject to U.S. Treasury regulations governing contingent debt instruments generally (the “Contingent Debt Regulations”) and foreign currency-linked contingent debt instruments specifically (the “Foreign Currency Regulations”). Each holder, by accepting a Note, agrees to this treatment of the Note and to report all income (or loss) with respect to the Note in accordance with the Foreign Currency Regulations and the Contingent Debt Regulations. The remainder of this summary assumes the treatment of each Note as a single debt instrument subject to the Foreign Currency Regulations and the Contingent Debt Regulations and the holder’s agreement thereto.

United States Holders

Under the Foreign Currency Regulations, the rules applicable to debt instruments that provide for payments determined by reference to multiple currencies depend on the “denomination currency” of the debt instrument. Because the present value of the principal payment, which is a fixed U.S. dollar amount, is greater than the present value of the projected amount attributable to the European Union Euro, the denomination currency of the Notes is the U.S. dollar. The Foreign Currency Regulations provide that the Notes consequently will be taxed pursuant to the rules contained in the Contingent Debt Regulations.

Taxation of Interest. A U.S. Holder of a Note will recognize income (or loss) on a Note in accordance with the Contingent Debt Regulations. The Contingent Debt Regulations require the application of a “noncontingent bond method” to determine accruals of income, gain, loss and deductions with respect to a contingent debt obligation. As described in more detail in the second and third succeeding paragraphs, under the noncontingent bond method, a U.S. Holder of a Note will be required for tax purposes to include in income each year an accrual of interest at the annual computational rate of 5.02%, compounded semi-annually (the “comparable yield”). The comparable yield is based on a rate at which Citigroup Funding could issue a fixed rate debt instrument with terms comparable to those of the Notes and no contingent payments. In addition, solely for purposes of determining the comparable yield pursuant to the Contingent Debt Regulations, a U.S. Holder of a Note will be assumed to be entitled to receive, in respect of each Note, a payment of US$1,104.25 at maturity (the “Projected Payment Amount”). The Projected Payment Amount is calculated as the amount required to produce the comparable yield, taking into account the Note’s issue price.

PS-15

The comparable yield and the Projected Payment Amount are used to determine accruals of interest FOR TAX PURPOSES ONLY and are not assurances or predictions by Citigroup Funding with respect to the actual yield of or payment to be made in respect of a Note. The comparable yield and the Projected Payment Amount do not necessarily represent Citigroup Funding’s expectations regarding such yield or the amount of such payment.

Each note will be issued at par. However, there will be original issue discount for U.S. federal income tax purposes (“Tax OID”) because a U.S. Holder must accrue income at the comparable yield. Under the Tax OID rules of the Internal Revenue Code of 1986, as amended (the “Code”), and the Treasury regulations promulgated thereunder, a U.S. Holder of a Note, whether such holder uses the cash or the accrual method of tax accounting, will be required to include as ordinary interest income the sum of the “daily portions” of Tax OID on the Note for all days during the taxable year that the U.S. Holder owns the Note. As a result, U.S. Holders of Notes, including U.S. Holders that employ the cash method of tax accounting, will be required to include amounts in respect of Tax OID accruing on Notes in taxable income each year although holders will receive no payments on the Notes prior to maturity.

The daily portions of Tax OID on a Note are determined by allocating to each day in any accrual period a ratable portion of the Tax OID allocable to that accrual period. In the case of an initial holder, the amount of Tax OID on a Note allocable to each accrual period is determined by multiplying the “adjusted issue price” (as defined below) of a Note at the beginning of the accrual period by the comparable yield of a Note (appropriately adjusted to reflect the length of the accrual period). The “adjusted issue price” of a Note at the beginning of any accrual period will generally be the sum of its issue price and the amount of Tax OID allocable to all prior accrual periods, less the amount of any payments made in all prior accrual periods. Based upon the comparable yield, if a U.S. Holder that employs the accrual method of tax accounting and pays taxes on a calendar year basis buys a Note at original issue for US$1,000 and holds it until maturity, such holder will be required to pay taxes on the following amounts of ordinary income from the Note for each of the following periods: US$12.97 in 2007; US$51.49 in 2008; and US$39.79 in 2009 (adjusted as described in the second paragraph below).

Disposition of the Notes. When a U.S. Holder sells, exchanges or otherwise disposes of the Note (including upon repayment of the Note at maturity) (a “disposition”), the U.S. Holder’s gain (or loss) on such disposition will equal the difference between the amount received by the U.S. Holder for the Note and the U.S. Holder’s tax basis in the Note. A U.S. Holder’s tax basis (i.e., adjusted cost) in a Note will be equal to the U.S. Holder’s original purchase price for such Note, plus any Tax OID accrued by the U.S. Holder and less the amount of any payments received by the holder while holding the Note.

If the amount received on the Note at maturity exceeds the Projected Payment Amount, the U.S. Holder will be required to include any such excess in income as ordinary income. Alternatively, if the amount received at maturity is less than the Projected Payment Amount, the difference between the Projected Payment Amount and the amount received at maturity will be treated as an offset to any interest otherwise includible in income by the U.S. Holder with respect to the Note for the taxable year in which maturity occurs, but only to the extent of the amount of such includible interest. Any remaining portion of such shortfall may be recognized and deducted by the U.S. Holder as an ordinary loss to the extent of the U.S. Holder’s previous Tax OID inclusions with respect to the Note.

On a disposition of a Note other than repayment of a Note at maturity, any gain realized by a U.S. Holder will be treated as ordinary interest income. Any loss realized by a U.S. Holder on a disposition will be treated as an ordinary loss to the extent of the U.S. Holder’s Tax OID inclusions with respect to the Note up to the date of disposition. Any loss realized in excess of such amount generally will be treated as a capital loss.

An individual U.S. Holder generally will be allowed a deduction for any ordinary loss without regard to the two-percent miscellaneous itemized deduction rule of Section 67 of the Code. Any capital loss recognized by a

PS-16

U.S. Holder will be a long-term capital loss if the U.S. Holder has held such Note for more than one year, and a short-term capital loss in other cases.

Information Reporting and Backup Withholding. Information returns may be required to be filed with the IRS relating to payments made to a particular U.S. Holder of Notes. In addition, U.S. Holders may be subject to backup withholding tax on such payments if they do not provide their taxpayer identification numbers in the manner required, fail to certify that they are not subject to backup withholding tax, or otherwise fail to comply with applicable backup withholding tax rules. U.S. Holders may also be subject to information reporting and backup withholding tax with respect to the proceeds from a sale, exchange, retirement or other taxable disposition of the Notes.

Non-United States Holders

The following is a summary of certain U.S. federal income tax consequences that will apply to Non-U.S. Holders of the Notes. The term “Non-U.S. Holder” means a beneficial owner of a Note that is a foreign corporation or nonresident alien.

Non-U.S. Holders should consult their own tax advisors to determine the U.S. federal, state and local and any foreign tax consequences that may be relevant to them.

Payment with Respect to the Notes. All payments on the Notes made to a Non-U.S. Holder, and any gain realized on a sale, exchange or redemption of the Notes, will be exempt from U.S. income and withholding tax, provided that:

(i) such Non-U.S. Holder does not own, actually or constructively, 10 percent or more of the total combined voting power of all classes of the Citigroup Funding’s stock entitled to vote, and is not a controlled foreign corporation related, directly or indirectly, to Citigroup Funding through stock ownership;

(ii) the beneficial owner of a Note certifies on Internal Revenue Service Form W-8BEN (or successor form), under penalties of perjury, that it is not a U.S. person and provides its name and address or otherwise satisfies applicable documentation requirements; and

(iii) such payments and gains are not effectively connected with the conduct by such Non-U.S. Holder to a trade or business in the United States.

If a Non-U.S. Holder of the Notes is engaged in a trade or business in the United States, and if interest on the Notes is effectively connected with the conduct of such trade or business, the Non-U.S. Holder, although exempt from the withholding tax discussed in the preceding paragraphs, generally will be subject to regular U.S. federal income tax on interest and on any gain realized on the sale, exchange or redemption of the Notes in the same manner as if it were U.S. Holder. In lieu of the certificate described in clause (ii) of the second preceding paragraph, such a Non-U.S. Holder will be required to provide to the withholding agent a properly executed Internal Revenue Service Form W-8ECI (or successor form) in order to claim an exemption from withholding tax.

Information Reporting and Backup Withholding. In general, a Non-U.S. Holder will not be subject to backup withholding and information reporting with respect to payments made with respect to the Notes if such Non-U.S. Holder has provided Citigroup Funding with an Internal Revenue Service Form W-8BEN described above and Citigroup Funding does not have actual knowledge or reason to know that such Non-U.S. Holder is a U.S. person. In addition, no backup withholding will be required regarding the proceeds of the sale of the Notes made within the United States or conducted through certain U.S. financial intermediaries if the payor receives the statement described above and does not have actual knowledge or reason to know that the Non-U.S. Holder is a U.S. person or the Non-U.S. Holder otherwise establishes an exemption.

PLAN OF DISTRIBUTION

The terms and conditions set forth in the Global Selling Agency Agreement dated April 20, 2006 among Citigroup Funding, Citigroup Inc. and the agents named therein, including Citigroup Global Markets Inc., govern the sale and purchase of the Notes.

Citigroup Global Markets Inc., as principal, has agreed to purchase from Citigroup Funding, and Citigroup Funding has agreed to sell to Citigroup Global Markets, $25,000,000 principal amount of Notes (25,000 Notes), any payments due on which are fully and unconditionally guaranteed by Citigroup Inc. Citigroup Global Markets proposes to offer some of the Notes directly to the public at market prices prevailing at the time of sale or at prices otherwise negotiated and some of the Notes to certain dealers at those prices less a concession not to exceed $11.40 per Note. Citigroup Global Markets may allow, and these dealers may reallow, a concession not to exceed $11.40 per Note on sales to certain other dealers.

The Notes will not be listed on any exchange.

In order to hedge its obligations under the Notes, Citigroup Funding expects to enter into one or more swaps or other derivatives transactions with one or more of its affiliates. You should refer to the section “Risk Factor Relating to the Notes—The Price at Which You Will Be Able to Sell Your Notes Prior to Maturity Will Depend on a Number of Factors and May Be Substantially Less Than the Amount You Originally Invest” in this pricing supplement, “Risk Factors—Citigroup Funding’s Hedging Activity Could Result in a Conflict of Interest” in the accompanying prospectus supplement and the section “Use of Proceeds and Hedging” in the accompanying prospectus.

Citigroup Global Markets is an affiliate of Citigroup Funding.
