Final Pricing Supplement

(To Prospectus Supplement Dated April 13, 2006 and Prospectus Dated March 10, 2006)

Investing in the notes involves a number of risks. See “ Risk Factors Relating to the Notes” beginning on page PS-2.

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

The notes are not deposits or savings accounts but are unsecured debt obligations of Citigroup Funding Inc. The notes are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or instrumentality.

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 basket currencies relative to the U.S. dollar, and other events that are difficult to predict and beyond our control.

The Use of the Sum of the Allocated Currency Returns on a Basket of Currencies Instead of a Single Currency Return May Lower the Return on Your Investment

Because the basket return percentage will be based upon the sum of the allocated currency return for each of the basket currencies (provided that the sign of the allocated percentage change in the value of the European Union euro relative to the U.S. dollar will be opposite to the sign of the percentage change in such value), a significant increase in the value of one or more of the currencies relative to the U.S. dollar (or a decrease in the case of the value of the European Union euro relative to the U.S. dollar) may be substantially or entirely offset by a decrease in the value of one or more of the other currencies in the basket relative to the U.S. dollar (or an increase in the case of the value of the European Union euro relative to the U.S. dollar) during the term of the notes.

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 basket return percentage is less than 4.516%, 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.

You will not receive any periodic payments of interest or other periodic payments on the notes.

The Values of the Basket Currencies and the U.S. Dollar Are Affected by Many Complex Factors

The value of any currency, including the basket currencies and the U.S. dollar, may be affected by complex political and economic factors. The value of each of the basket currencies relative to the U.S. dollar, as measured by the relevant exchange rate, is at any moment a result of the supply and demand for the relevant currencies, and changes in the exchange rates result over time from the interaction of many factors directly or indirectly affecting economic and political conditions in the Russian Federation, the Republic of Turkey, the Republic of Indonesia, 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 Russian Federation, the Republic of Turkey, the Republic of Indonesia, 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 Russian Federation, the Republic of Turkey, the Republic of Indonesia, 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 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 of the notes in the event that exchange rates 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 basket currencies or the U.S. dollar specifically, or any other currency.

There Are Particular Risks Associated with Notes Linked to the Value of the Russian Ruble

Investments in or related to emerging markets such as the Russian Federation are subject to greater risks than those in more developed markets. An increase in the value of the notes may depend on the Russian ruble appreciating in value against the U.S. dollar. In turn, that value will depend, as for any currency, on a number of interrelated factors such as those noted above, some of which may be particular to the Russian ruble.

At various times since the dissolution of the Soviet Union, the Russian economy has experienced significant problems, including, among others, declines in gross domestic product, hyperinflation, an unstable currency, high levels of public sector debt, capital flight and significant increases in unemployment. In August 1998, in the face of a rapidly deteriorating economic situation, the Russian government defaulted on its ruble-denominated securities, the Central Bank of Russia stopped its support of the Russian ruble and a temporary moratorium was imposed on certain foreign currency payments. This led to a deterioration in the value of the Russian ruble, a sharp increase in the rate of inflation, a near collapse of the banking system and a lack of access for Russian issuers to international capital markets. While since the 1998 crisis the Russian economy has experienced positive trends, including a more stable Russian ruble, reduced inflation levels and positive capital and current account balances resulting in part from rising world prices for crude oil, gas and other commodities that Russia exports, there can be no assurance that this positive situation will continue.

Under changes in the regulations of the Central Bank of Russia, convertibility of the Russian ruble was liberalized as of July 1, 2006. One cannot predict what impact this development will have on exchange rates between the Russian ruble and the U.S. dollar and other currencies, particularly given the limited development of the foreign currency market in the Russian Federation. Certain currency regulations have not been repealed, such as the general prohibition on foreign currency operations between Russian companies (other than authorized banks) and a requirement on Russian companies, subject to certain exceptions, to repatriate export-related earnings. Furthermore, it is possible, particularly during this transition period, that the Central Bank of Russia may be more likely than central banks in more developed economies to use the various tools at the disposal of a central bank, including those referred to above, to intervene in foreign exchange markets for the Russian ruble or take other regulatory action that could impact the value of the Russian ruble and possibly adversely affect the value of your notes.

In addition to the risks more directly related to the Russian economy and the policies of the Russian government, financial problems in, or an increase in perceived risks associated with, other emerging markets could impair confidence in the Russian economy and adversely affect the value of the Russian ruble in relation to the U.S. dollar and, therefore, the value of your 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

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 each of the basket currencies relative to the U.S. dollar, as measured by the relevant 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 Basket Currency Exchange Rates. We expect that the market value of the notes at any given time will likely depend substantially on the changes, if any, in the value of each of the basket currencies relative to the U.S. dollar from their respective starting values. For example, increases in the value of one or more of the basket currencies relative to the U.S. dollar (or a decrease in the case of the value of the European Union euro relative to the U.S. dollar) (as measured by a decrease in the corresponding exchange rate from its starting value (or an increase from its starting value in the case of the U.S. dollar/European Union euro exchange rate)) may cause an increase in

the market value of the notes because of the expectation that the maturity payment on the notes will increase. Conversely, decreases in the value of one or more of the basket currencies relative to the U.S. dollar (or an increase in the case of the value of the European Union euro relative to the U.S. dollar) (as measured by an increase in the corresponding exchange rate from its starting value (or a decrease in its starting value in the case of the U.S. dollar/European Union euro exchange rate)) may cause a decrease in the market value of the notes because of the expectation that the maturity payment on the notes will decrease. If you choose to sell your notes when the value of one or more of the basket currencies relative to the U.S. dollar has declined, as measured by one or more of the respective exchange rates being above its respective value, you will likely receive less than the amount you originally invested.

The values of the basket currencies 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 basket currencies and the U.S. dollar are traded. Some of these factors are described in more detail in “—The Values of the Basket Currencies and the U.S. Dollar Are Affected by Many Complex Factors” above.

Volatility of the Basket Currencies. Volatility is the term used to describe the size and frequency of market fluctuations. If the expected volatility of the value of each of the basket currencies relative to the U.S. dollar changes, as measured by the relevant 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 countries issuing the basket currencies may decrease the future value of the basket currencies relative to the U.S. dollar, which would generally tend to decrease the value of the notes. Conversely, decreases in U.S. interest rates relative to interest rates in the countries issuing the basket currencies may increase the future value of the basket currencies relative to the U.S. dollar, which would generally tend to increase the value of the notes.

Decreases in interest rates in the countries issuing the basket currencies relative to U.S. interest rates may decrease the future values of the basket currencies relative to the U.S. dollar, which would tend to decrease the value of the notes, and increases in interest rates in the countries issuing the basket currencies relative to U.S. interest rates may increase the future values of the basket currencies relative to the U.S. dollar, which would generally tend to increase the value of the notes. Interest rates may also affect the economies of the countries issuing the basket currencies or of the United States and, in turn, the value of each of the basket currencies relative to the U.S. dollar, as measured by the relevant 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 basket currencies 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 each of the basket currencies 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.

Hedging Activities. Hedging activities related to the notes by one or more of our affiliates will likely involve trading in one or more of the basket currencies or in the other instruments, such as options, swaps or futures, based upon one or more of the relevant exchange rates or the basket currencies. 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 Inc. may be willing to purchase your notes in the secondary market.

Credit Ratings, Financial Condition and Results. Actual or anticipated changes in Citigroup Funding’s 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 Basket Currencies Is Not an Indication of the Future Performance of the Basket Currencies

The historical performance of each of the basket currencies relative to the U.S. dollar, as measured by the relevant exchange rate, which is included in this pricing supplement, should not be taken as an indication of the future performance of the relevant exchange rates during the term of the notes. Changes in the value of each basket currency relative to the U.S. dollar will affect the trading price of the notes, but it is impossible to predict whether the value of any of the basket currencies relative to the U.S. dollar will rise or fall.

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 basket currencies 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’ 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.

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.

The Principal-Protected Notes Based Upon a Basket of Currencies Due April 24, 2010 (the “Notes”) are currency basket-linked securities issued by Citigroup Funding that have a maturity of approximately two years. The Notes pay an amount at maturity that will depend on the allocated percentage change in the value of each Basket Currency relative to the U.S. dollar, as measured by each relevant exchange rate, over the term of the Notes. The Basket Currencies are the Russian ruble, Turkish lira, Indonesian rupiah and European Union euro. If the sum of the allocated percentage change in the value of each of the Basket Currencies relative to the U.S. dollar, as measured by each relevant exchange rate, from April 21, 2008 to the Valuation Date is less than or equal to zero (provided that the sign of the allocated percentage change in the value of the European Union euro relative to the U.S. dollar will be opposite to the sign of the percentage change in such value), the payment you receive at maturity will equal US$1,020 per Note or 102% of your initial investment in the Notes. If the sum of the allocated percentage change in the value of each of the Basket Currencies relative to the U.S. dollar, as measured by each relevant exchange rate, from April 21, 2008 to the Valuation Date is greater than zero (provided that the sign of the allocated percentage change in the value of the European Union euro relative to the U.S. dollar will be opposite to the sign of the percentage change in such value), the payment you receive at maturity will equal 100% of your initial investment in the Notes plus a Basket Return Amount, which will be not less than US$20 per Note.

The performance of each of the Basket Currencies is measured by its exchange rate. Each exchange rate reflects the amount of the relevant Basket Currency that can be exchanged for one U.S. dollar. Thus, an increase in a Basket Currency’s exchange rate means that the value of that currency has decreased. For example, if the USDTRY Exchange Rate has increased from 1.00 to 2.00, it means the value of one Turkish lira (as measured against the U.S. dollar) has decreased from US$1.00 to US$0.50. Conversely, a decrease in a Basket Currency’s exchange rate means that the value of that currency has increased.

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$3,800,000 (3,800 Notes). The Notes will mature on April 24, 2010, 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, including payment of principal, 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.

We will not make any periodic payments of interest on the Notes or any other payments on the Notes during the term of the Notes.

The Notes will mature on April 24, 2010. 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 Basket Return Amount, which will be not less than US$20 per Note.

If the Basket Return Percentage is less than or equal to zero, the Basket Return Amount will equal the product of (a) US$1,000 and (b) 2% ($20 per Note). If the Basket Return Percentage is greater than zero, the Basket Return Amount will equal the product of (a) US$1,000 and (b) 2% plus the product of (i) the Basket Return Percentage and (ii) the Participation Rate. The Participation Rate equals 120%.

The Basket Return Percentage will equal the sum of the Allocated Currency Return for each of the Basket Currencies, expressed as a percentage (provided that the sign of the allocated percentage change in the value of the European Union euro relative to the U.S. dollar will be opposite to the sign of the percentage change in such value).

The Allocated Currency Return for each Basket Currency will equal the following fraction:

The Allocation Fraction for the Russian ruble, Turkish lira and Indonesian rupiah will each equal ¹/3.

The Starting Exchange Rate for the Russian ruble equals the USDRUB Exchange Rate on April 21, 2008, which was 23.4132. The Starting Exchange Rate for the Turkish lira equals the USDTRY Exchange Rate on April 21, 2008, which was 1.3132. The Starting Exchange Rate for the Indonesian rupiah equals the USDIDR Exchange Rate on April 21, 2008, which was 9193. The Starting Exchange Rate for the European Union euro equals the USDEUR Exchange Rate on April 21, 2008, which was 0.6290.

The Ending Exchange Rate for the Russian ruble, Turkish lira, Indonesian rupiah and European Union euro will equal the USDRUB, USDTRY, USDIDR and USDEUR Exchange Rate, respectively, on the Valuation Date, each as calculated by the Calculation Agent or reported, as described below.

The USDRUB Exchange Rate equals the U.S. dollar/Russian ruble exchange rate in the global spot foreign exchange market, expressed as the amount of Russian rubles per one U.S. dollar, as reported by Reuters on Page “EMTA,” or any substitute page, on any relevant date.

The USDTRY Exchange Rate equals the U.S. dollar/Turkish lira exchange rate in the global spot foreign exchange market, expressed as the amount of Turkish lira per one U.S. dollar. The USDTRY Exchange Rate is calculated by the Calculation Agent by dividing the “TRY” exchange rate by the “USD” exchange rate, each as reported by Reuters on Page “ECB3,” or any substitute page, on any relevant date.

The USDIDR Exchange Rate equals the U.S. dollar/Indonesian rupiah exchange rate in the global spot foreign exchange market, expressed as the amount of Indonesian rupiahs per one U.S. dollar, as reported by Reuters on Page “ABSIRFIX01,” or any substitute page, on any relevant date.

The USDEUR Exchange Rate equals the U.S. dollar/European Union euro exchange rate in the global spot foreign exchange market, expressed as the amount of European Union euros per one U.S. dollar. The USDEUR Exchange Rate is calculated by dividing 1 by the “USD” exchange rate, as reported by Reuters on Page “ECB3,” or any substitute page, on any relevant date.

If either of the USDRUB or USDIDR Exchange Rates are not so reported on Reuters Pages “EMTA” or “ABSIRFIX01,” or any substitute pages thereto, or if any of the exchange rates used to calculate the USDTRY or USDEUR Exchange Rates are not so reported on Reuters Page “ECB3,” or any substitute page thereto, then the USDRUB, USDTRY, USDIDR and USDEUR Exchange Rates, as applicable, 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 relevant currency 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 relevant 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 City (selected by the Calculation Agent after consultation with Citigroup Funding), for the purchase or sale for deposits in the relevant currencies. If these spot quotations are available from only one bank, then the Calculation Agent, in its sole discretion, will determine if such quotation is reasonable. If no spot quotation is available, then the relevant 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 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 are authorized or obligated by law or executive order to close.

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.”

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 4% 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.

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.

The Calculation Agent for the Notes will be Citigroup Financial Products. 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 is obligated to carry out its duties and functions as Calculation Agent in good faith and using its reasonable judgment.

The Basket Currencies are the Russian ruble, Turkish lira, Indonesian rupiah and European Union euro. Exchange rates are used to measure the value of each of the Basket Currencies relative to the U.S. dollar.

The relevant exchange rates are foreign exchange spot rates that measure the relative values of two currencies, the Russian ruble and the U.S. dollar in the case of the USDRUB Exchange Rate, the Turkish lira and the U.S. dollar in the case of the USDTRY Exchange Rate, the Indonesian rupiah and the U.S. dollar in the case of the USDIDR Exchange Rate and the European Union euro and the U.S. dollar in the case of the USDEUR Exchange Rate. Each exchange rate is expressed as an amount of the relevant Basket Currency that can be exchanged for one U.S. dollar. Thus, an increase in the value of any Basket Currency will cause a decrease in its exchange rate, while a decrease in the value of any Basket Currency will cause an increase in its exchange rate.

We have obtained all information in this pricing supplement relating to the Russian ruble, Turkish lira, Indonesian rupiah and European Union euro and the relevant exchange rates from public sources, without independent verification. Currently, the relevant exchange rates are 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 each Basket Currency relative to the U.S. dollar, as measured by the relevant exchange rate, will be determined as described in “Description of the Notes—Basket Return Amount” above.

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

The USDRUB Exchange Rate appearing on Reuters Page “EMTA” on April 21, 2008 was 23.4132. The USDTRY Exchange Rate, calculated by dividing the “TRY” exchange rate by the “USD” exchange rate, each appearing on Reuters Page “ECB3” on April 21, 2008, was 1.3132. The USDIDR Exchange Rate appearing on Reuters Page “ABSIRFIX01” on April 21, 2008 was 9193. The USDEUR Exchange Rate, calculated by dividing 1 by the “USD” exchange rate appearing on Reuters Page “ECB3” on April 21, 2008, was 0.6290.

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.

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.

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 each of the currencies in the basket, 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 3.61%, 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$1,074.19 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.

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$24.79 in 2008; US$37.34 in 2009; and US$12.07 in 2010 (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. Any capital loss recognized by a 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.
