an amount equal to the product of (a) $10 and (b) the absolute value of the positive or negative percentage change in the closing value of the S&P MidCap 400® Index from the date of this pricing supplement (which we refer to as the pricing date) to the third index business day before maturity (which we refer to as the valuation date), if the closing value of the S&P MidCap 400® Index on every index business day from the pricing date up to and including the valuation date is BOTH less than or equal to 1,096.07 (approximately 134.50% of the closing value of the S&P MidCap 400® Index on the pricing date) AND greater than or equal to 651.94 (approximately 80% of the closing value of the S&P MidCap 400® Index on the pricing date), or

(ii)

zero in all other circumstances.

SUMMARY INFORMATION — Q&A

What Are the Notes?

The Contingent Absolute Return Principal Protected Notes Based Upon the Absolute Return of the S&P MidCap 400^® Index are notes offered by Citigroup Funding Inc. that have a maturity of approximately 2 years. The notes pay an amount at maturity that will depend on the closing value of the S&P MidCap 400^® Index being within a specified range on every index business day from the pricing date up to and including the valuation date. If the closing value of the S&P MidCap 400^® Index on every index business day from the pricing date up to and including the valuation date is BOTH less than or equal to 1,096.07 (approximately 134.50% of the starting value) AND greater than or equal to 651.94 (approximately 80% of the starting value), the payment you receive at maturity for each note you then hold may be greater than $10 per note. If, however, the closing value of the S&P MidCap 400^® Index on any index business day from the pricing date up to and including the valuation date is greater than 1,096.07 (approximately 134.50% of the starting value) or is less than 651.94 (approximately 80% of the starting value), the return on a note will be zero, regardless of whether the ending value is greater than or less than the starting value. In addition, if the ending value equals the starting value, at maturity you will receive only your initial investment in the notes even if the closing value of the S&P MidCap 400^® Index on every index business day during the term of the notes is within the specified range.

The notes mature on September 7, 2010 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 Inc. Any payments due on the notes are fully and unconditionally guaranteed by Citigroup Inc. The notes will rank equally with all other unsecured and unsubordinated debt of Citigroup Funding, and the guarantee of any payments due under the notes, including payment of principal, will rank equally with all other unsecured and unsubordinated debt of Citigroup Inc.

Each note represents a principal amount of $10. You may transfer the notes only in units of $10 and integral multiples of $10. 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 Banking clearance systems may hold beneficial interests in the notes through the accounts those systems maintain with DTC. You should refer to the section “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.

What Does “Principal Protected” Mean?

“Principal protected” means that your principal investment in the notes will be returned to you if held to maturity even if there is a decline in the value of the S&P MidCap 400^® Index. Thus, you will not receive less than $10 per $10 principal amount of notes if you hold the notes to maturity.

Will I Receive Periodic Interest on the Notes?

No. We will not make any periodic payments of interest on the notes or any other periodic payments on the notes. In addition, you will not be entitled to receive dividend payments or other distributions, if any, made on the stocks included in the S&P MidCap 400^® Index.

What Will I Receive at Maturity of the Notes?

The notes will mature on September 7, 2010. At maturity you will receive for each note you hold an amount in cash equal to the sum of $10 and a note return amount, which may be positive or zero. The amount payable to you at maturity depends upon the ending value of the S&P MidCap 400^® Index. The payment you receive at maturity for each note you then hold, however, will not be less than the amount of your original investment of $10 per note for each note you hold at maturity.

PS-2

How Will the Note Return Amount Be Calculated?

The note return amount will depend on the closing value of the S&P MidCap 400^® Index being within a specified range during the term of the notes, will be based on the percentage change in the value of the S&P MidCap 400^® Index during the term of the notes, and may be positive or zero.

Thus, for each note held at maturity, you will receive $10 plus:

(i) an amount equal to the product of (a) $10 and (b) the absolute value of the positive or negative percentage change in the closing value of the S&P MidCap 400^® Index from the pricing date to the valuation date, if the closing value of the S&P MidCap 400^® Index on every index business day from the pricing date up to and including the valuation date is BOTH less than or equal to 1,096.07 (approximately 134.50% of the closing value of the S&P MidCap 400^® Index on the pricing date) AND greater than or equal to 651.94 (approximately 80% of the closing value of the S&P MidCap 400^® Index on the pricing date), or

(ii) zero in all other circumstances.

The absolute index return percentage will equal the percentage change in the closing value of the S&P MidCap 400^® Index from the pricing date to the valuation date, without regard to whether the change was positive or negative, expressed as a percentage:

Ending Value − Starting Value

Starting Value

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

The starting value equals 814.92, the closing value of the S&P MidCap 400^® Index on the pricing date.

The ending value will equal the closing value of the S&P MidCap 400^® Index on the valuation date.

The pricing date means August 22, 2008, the date of this pricing supplement and the date on which the notes were initially priced for sale to the public.

The valuation date will be the third index business day before the maturity date.

For more specific information about the “note return amount,” the determination of an “index business day” and the effect of a market disruption event on the determination of the note return amount, please see “Description of the Notes — Note Return Amount” in this pricing supplement.

Where Can I Find Examples of Hypothetical Returns at Maturity?

For tables setting forth hypothetical returns at maturity, see “Description of the Notes — Hypothetical Returns at Maturity” in this pricing supplement.

What is the S&P MidCap 400^® Index and What Does It Measure?

Unless otherwise stated, all information on the S&P MidCap 400^® Index provided in this pricing supplement is derived from Standard & Poor’s, which we refer to as S&P, or other publicly available sources. The S&P MidCap 400^® Index is published by S&P and is intended to provide a performance benchmark for the medium capitalization segment of the U.S. equity markets. It tracks the stock price movement of 400 companies with mid-sized market capitalizations, primarily ranging from $1.5 billion to $5.5 billion. As of June 30, 2008, the largest five sectors represented by the S&P MidCap 400^® Index were Financials, Information Technology, Industrials, Consumer Discretionary and Energy. For further information on the S&P MidCap 400^® Index, including its makeup, method of calculation and changes in its components, see “Description of the S&P MidCap 400^® Index” in this pricing supplement.

PS-3

Please note that an investment in the notes does not entitle you to any dividends, voting rights or any other ownership or other interest in respect of the stocks of the companies included in the S&P MidCap 400^® Index.

How Has the S&P MidCap 400^® Index Performed Historically?

We have provided a table showing the high and low closing values of the S&P MidCap 400^® Index for each month from January 2003 to July 2008 and a graph showing the closing values of the S&P MidCap 400^® Index on each index business day from January 2, 2003 to August 22, 2008. You can find the table and the graph in the section “Description of the S&P MidCap 400^® Index — Historical Data on the S&P MidCap 400^® Index” in this pricing supplement. We have provided this historical information to help you evaluate the behavior of the S&P MidCap 400^® Index in recent years. However, past performance is not indicative of how the S&P MidCap 400^® Index will perform in the future. You should also refer to the section “Risk Factors — The Historical Performance of the S&P MidCap 400^® Index Is Not an Indication of the Future Performance of the S&P MidCap 400^® Index” in this pricing supplement.

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 4.4503% 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 representing all amounts payable on the notes. This assumed amount is neither a prediction nor guarantee of the actual yield of, or payments 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). Special rules will apply if the S&P MidCap 400^® Index is greater than 1,096.07 (approximately 134.50% of the starting value) or is less than 651.94 (approximately 80% of the starting value) at any time before six months prior to maturity, so that the amount paid at the maturity of the notes would become fixed. 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 Inc. and Citigroup Funding?

Citigroup Inc. 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 Inc. whose business activities consist primarily of providing funds to Citigroup Inc. and its subsidiaries for general corporate purposes.

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

Our affiliate, Citigroup Global Markets, is the agent for the offering and sale of the notes and is expected to receive compensation for activities and services provided in connection with the offering. After the initial offering, Citigroup Global Markets and/or other of our broker-dealer affiliates intend to buy and sell the notes

PS-4

to create a secondary market for holders of the notes, and may engage in other activities described in the sections “Plan of Distribution” in this pricing supplement, the accompanying prospectus supplement and prospectus. However, neither Citigroup Global Markets nor any of these affiliates will be obligated to engage in any market-making activities, or continue such activities once it has started them. Citigroup Global Markets will also act as calculation agent for the notes. Potential conflicts of interest may exist between Citigroup Global Markets and you as a holder of the notes.

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 one or more stocks included in the S&P MidCap 400^® Index or in other instruments, such as options, swaps or futures, based upon the S&P MidCap 400^® Index or the stocks included in the S&P MidCap 400^® Index. This hedging activity could affect the value of the S&P MidCap 400^® Index and therefore the market value of the notes. The costs of maintaining or adjusting this hedging activity could also 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 the receipt of a profit by our affiliates or us, 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” 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, 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 purchase or hold the notes if the account, plan or annuity is for the benefit of an employee of Citigroup Global Markets 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.

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

Because the terms of the notes differ from those of conventional debt securities, an investment in the notes entails significant risks not associated with an investment in conventional debt securities, including, among other things, fluctuations in the value of the stocks which comprise the S&P MidCap 400^® Index and other events that are difficult to predict and beyond our control.

The Return on Your Notes May Be Zero

Your note return amount at maturity will depend on the closing value of the S&P MidCap 400^® Index on every index business day from the pricing date up to and including the valuation date and will be based on the ending value of the S&P MidCap 400^® Index. If the closing value of the S&P MidCap 400^® Index on any index business day from the pricing date up to and including the valuation date is greater than 1,096.07 (approximately 134.50% of the starting value) or is less than 651.94 (approximately 80% of the starting value), the payment you receive at maturity will be limited to your initial investment in the notes, even if the ending value of the S&P MidCap 400^® Index is greater than or less than its starting value. In addition, if the ending value equals the starting value, at maturity you will receive only your initial investment in the notes even if the closing value of the S&P MidCap 400^® Index on every index business day during the term of the notes is within the specified range. Because of the possibility of a zero return, the notes may provide less opportunity for return than an investment that would permit you to participate fully in the appreciation of the S&P MidCap 400^® Index or an investment in some or all of the stocks included in the S&P MidCap 400^® Index.

The Appreciation of Your Investment in the Notes Will Be Limited

The return on your notes may be less than the return on an investment that would permit you to participate fully in the appreciation of the S&P MidCap 400^® Index or an investment in the stocks included in the S&P MidCap 400^® Index. Because the note return amount is based on the absolute value of the positive or negative percentage change in the closing value of the S&P MidCap 400^® Index from the pricing date to the valuation date and because the note return amount will equal zero if the closing value of the S&P MidCap 400^® Index on any index business day from the pricing date up to and including the valuation date is greater than 1,096.07 (approximately 134.5% of the starting value) or is less than 651.94 (approximately 80% of the starting value), the note return amount will not exceed approximately 34.50% (or approximately 16.99% per annum on a simple interest basis) of your initial investment in the notes. In addition, if the ending value equals the starting value, at maturity you will receive only your initial investment in the notes even if the closing value of the S&P MidCap 400^® Index on every index business day during the term of the notes is within the specified range.

You Will Not Receive Any Periodic Payments on the Notes

You will not receive any periodic interest payments or any other periodic payments on the notes. In addition, you will not be entitled to receive dividend payments or other distributions, if any, made on the stocks included in the S&P MidCap 400^® Index.

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 if you sell your notes in the secondary market prior to maturity, you may receive less than your initial investment.

Your Return on the Notes Will Not Reflect the Return You Would Realize if You Actually Owned the Stocks Included in the S&P MidCap 400^® Index

Your return, if any, on the notes will not reflect the return you would realize if you actually owned the stocks included in the S&P MidCap 400^® Index because the note return amount does not take into consideration the value of any dividends paid on the underlying stocks. As a result, the return on the notes

PS-6

may be less than the return you would realize if you actually owned the stocks included in the S&P MidCap 400^® Index, even if you participate fully in the appreciation in the value of the S&P MidCap 400^® Index.

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, even if the closing value of the S&P MidCap 400^® Index has stayed within the specified range during the term of the Notes, if the ending value of the S&P MidCap 400^® Index is less than 1,096.07 or more than 651.94, the yield on the notes will be less than that which would be payable on a conventional fixed-rate debt security of Citigroup Funding of comparable maturity. The return on the Notes may be zero.

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 may, but is 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 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.

Special U.S. Federal Income Tax Rules Will Apply to U.S. Holders

The Notes will be treated by Citigroup Funding as contingent payment debt obligations of Citigroup Funding, and by accepting a Note, each holder of a Note agrees to this treatment of the Note. Special U.S. federal income tax rules apply to contingent payment debt obligations. Under these rules, a U.S. holder will be required to accrue interest income on the Note although U.S. holders will receive no payments with respect to the Note before maturity and regardless of whether the U.S. Depositor uses the cash or accrual method of tax accounting. In addition, upon the sale, exchange or other disposition of a Note, including redemption of the Note at maturity, a U.S. holder generally 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 the section “Certain United States Federal Income Tax Considerations” in this pricing supplement for more information.

The Price at Which You Will Be Able to Sell Your Notes Will Depend on a Number of Factors

We believe that the value of your notes will be affected by the supply of and demand for the notes, the value of the S&P MidCap 400^® Index, interest rates, 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.

Value of the S&P MidCap 400^® Index.  We expect that the market value of the notes will depend substantially on the amount, if any, by which the value of the S&P MidCap 400^® Index changes from the starting value. However, changes in the value of the S&P MidCap 400^® Index may not always be reflected, in full or in part, in the market value of the notes. If you choose to sell your notes prior to maturity, even if the closing value of the S&P MidCap 400^® Index has been less than or equal to 1,096.07 (approximately 134.50% of the starting value) and has been greater than or equal to 651.94 (approximately 80% of the starting value) at all times during the term of the notes up to and including the time of sale, you may receive substantially less than the amount that would be payable at maturity based on the closing value at the time of sale because of expectations that the value of the S&P MidCap 400^® Index will continue to fluctuate between that time and the time when the ending value of the S&P MidCap 400^® Index is determined. In addition, significant increases or decreases in the closing value of S&P MidCap 400^® Index may result in a decrease in the market value of the notes because if the closing value of the S&P MidCap 400^® Index on any index business day after the pricing date up to and including the valuation date is greater than 1,096.07 (approximately 134.50% of the starting value) or is less than 651.94 (approximately 80% of the starting value), the amount you can

PS-7

receive at maturity for each $10 note you then hold will be limited to $10 and the note return amount will be zero.

Volatility of the S&P MidCap 400^® Index.  Volatility is the term used to describe the size and frequency of market fluctuations. If the expected volatility of the S&P MidCap 400^® Index changes during the term of the notes, the market value of the notes in the secondary market may decrease.

Events Involving the Companies Included in the S&P MidCap 400^® Index.  General economic conditions and earnings results of the companies whose stocks are included in the S&P MidCap 400^® Index and real or anticipated changes in those conditions or results may affect the market value of the notes. In addition, if the dividend yields on those stocks increase, we expect that the market value of the notes may decrease because the note return amount does not incorporate the value of dividend payments. Conversely, if dividend yields on the stocks decrease, we expect that the market value of the notes may increase.

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 in the secondary market may increase.

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 S&P MidCap 400^® Index. A “time premium” or “discount” results from expectations concerning the value of the S&P MidCap 400^® Index 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, 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 stocks included in the S&P MidCap 400^® Index or in the other instruments, such as options, swaps or futures, based upon the S&P MidCap 400^® Index or the stocks included in the S&P MidCap 400^® Index. This hedging activity could affect the value of the S&P MidCap 400^® Index and therefore the market value of the notes. It is possible that our affiliates may profit from this hedging activity, even if the market value of the notes declines. Profit or loss from 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.

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 value of the notes. The notes are subject to the credit risk of Citigroup Inc., the guarantor of the 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 S&P MidCap 400^® Index Is Not an Indication of the Future Performance of the S&P MidCap 400^® Index.

The historical performance of the S&P MidCap 400^® Index, which is included in this pricing supplement, should not be taken as an indication of the future performance of the S&P MidCap 400^® Index during the term of the notes. Changes in the value of the S&P MidCap 400^® Index will affect the value of the notes, but it is impossible to predict whether the value of the S&P MidCap 400^® Index will fall or rise.

You Will Have No Rights Against the Publisher of, or Any Issuer of Any Stock Included in, the S&P MidCap 400^® Index.

You will have no rights against the index publisher of, or any issuer of any stock included in, the S&P MidCap 400^® Index, even though the amount you receive at maturity will depend in part on the prices of the stocks included in the S&P MidCap 400^® Index. By investing in the notes you will not acquire any shares of

PS-8

stocks included in the S&P MidCap 400^® Index and you will not receive any dividends or other distributions with respect to stocks included in the S&P MidCap 400^® Index. The index publisher and the issuers of the stocks included in the S&P MidCap 400^® Index are not in any way involved in this offering and have no obligations relating to the notes or to the holders of the notes.

The Market Value of the Notes May Be Affected by Purchases and Sales of the Stocks Included in the S&P MidCap 400^® Index or Related Derivative Instruments by Affiliates of Citigroup Funding

Citigroup Funding’s affiliates, including Citigroup Global Markets, may from time to time buy or sell the stocks included in the S&P MidCap 400^® Index or derivative instruments related to such stocks or index for their own accounts in connection with their normal business practices. These transactions could affect the value of the stocks included in the S&P MidCap 400^® Index and therefore the market value of the notes.

Citigroup Global Markets, an Affiliate of Citigroup Funding and Citigroup Inc., Is the Calculation Agent, Which Could Result in a Conflict of Interest

Citigroup Global Markets, which is acting as the calculation agent for the notes, is an affiliate of ours. As a result, Citigroup Global Markets’ 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.

Citigroup Funding’s Hedging Activity Could Result in a Conflict of Interest

In anticipation of the sale of the notes, we expect one or more of our affiliates to enter into hedge transactions. This hedging activity will likely involve trading in one or more of the stocks included in the S&P MidCap 400^® Index or in other instruments, such as options, swaps or futures, based upon the S&P MidCap 400^® Index or the stocks included in the S&P MidCap 400^® Index. This hedging activity may present a conflict between your interest in the notes and the interests our affiliates have in executing, maintaining and adjusting their hedge transactions because it could affect the value of the S&P MidCap 400^® Index and therefore the market value of the notes. It could also be adverse to your interest if it affects the price at which our affiliate Citigroup Global Markets may be willing to purchase your notes in the secondary market. Since hedging the obligations under the notes involves risk and may be influenced by a number of factors, it is possible that our affiliates may profit from the hedging activity, even if the market value of the notes declines.

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 description of the general terms and provisions of the debt securities set forth in the accompanying prospectus supplement and prospectus.

General

The Contingent Absolute Return Principal Protected Notes Based Upon the Absolute Return of the S&P MidCap 400^® Index (the “Notes”) are securities offered by Citigroup Funding Inc. that have a maturity of approximately 2 years. The Notes pay an amount at maturity that will depend on the closing value of the S&P MidCap 400^® Index being within a specified range on every Index Business Day from the Pricing Date up to and including the Valuation Date. If the closing value of the S&P MidCap 400^® Index on every Index Business Day from the Pricing Date up to and including the Valuation Date is BOTH less than or equal to 1,096.07 (approximately 134.50% of the Starting Value) AND greater than or equal to 651.94 approximately 80% of the Starting Value), the payment you receive at maturity for each Note you then hold may be greater than $10 per Note. If, however, the closing value of the S&P MidCap 400^® Index on any Index Business Day from the Pricing Date up to and including the Valuation Date is greater than 1,096.07 (approximately 134.50% of the Starting Value) or is less than 651.94 (approximately 80% of the Starting Value), the return on a Note will be zero, regardless of whether the Ending Value is greater than or less than the Starting Value. In addition, if the Ending Value equals the Starting Value, at maturity you will receive only your initial investment in the Notes even if the closing value of the S&P MidCap 400^® Index on every Index Business Day during the term of the Notes is within the specified range.

The Notes are a series of debt securities issued under the senior debt indenture described in the accompanying prospectus, any payments on which are fully and unconditionally guaranteed by Citigroup Inc. The aggregate principal amount of Notes issued will be $36,150,000 (3,615,000 Notes). The Notes will mature on September 7, 2010. The Notes will constitute part of the senior debt of Citigroup Funding and will rank equally with all other unsecured and unsubordinated debt of Citigroup Funding. The guarantee of 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 $10 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 or any other periodic payments on the Notes. Also, you will not be entitled to receive dividend payments or other distributions, if any, made on the stocks included in the S&P MidCap 400^® Index.

Payment at Maturity

The Notes will mature on September 7, 2010. If you hold your Note to maturity, you will receive at maturity for each $10 principal amount note an amount in cash equal to $10 plus a Note Return Amount, which may be positive or zero.

Note Return Amount

The Note Return Amount will depend on the closing value of the S&P MidCap 400^® Index being within a specified range during the term of the Notes, will be based on the percentage change in the value of the S&P MidCap 400^® Index during the term of the Notes, and may be positive or zero. Thus, for each $10 Note held at maturity, you will receive $10 plus:

(i) an amount equal to the product of (a) $10 and (b) the Absolute Index Return Percentage, if the closing value of the S&P MidCap 400^® Index on every Index Business Day from the Pricing Date up to

PS-10

and including the Valuation Date is BOTH less than or equal to 1,096.07 (approximately 134.50% of the Starting Value) AND greater than or equal to 651.94 (approximately 80% of the Starting Value), or

(ii) zero in all other circumstances.

The Absolute Index Return Percentage will equal the percentage change in the closing value of the S&P MidCap 400^® Index from the Pricing Date to the Valuation Date, without regard to whether the change was positive or negative, expressed as a percentage:

Ending Value − Starting Value

Starting Value

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

The Starting Value equals 814.92, the closing value of the S&P MidCap 400^® Index on the Pricing Date.

The Ending Value will equal the closing value of the S&P MidCap 400^® Index on the Valuation Date.

The Pricing Date means August 22, 2008, the date of this pricing supplement and the date on which the Notes were initially priced for sale to the public.

The Valuation Date will be the third Index Business Day before the maturity date.

If the value of the S&P MidCap 400^® Index is not available on any determination date because of a Market Disruption Event or otherwise, the value of the S&P MidCap 400^® Index for that day, unless deferred by the calculation agent as described below, will be the arithmetic mean, as determined by the calculation agent, of the value of the S&P MidCap 400^® Index obtained from as many dealers in equity securities (which may include Citigroup Global Markets or any of our other affiliates), but not exceeding three such dealers, as will make such value available to the calculation agent. The determination of the value of the S&P MidCap 400^® Index made by the calculation agent in the event of a Market Disruption Event may be deferred by the calculation agent for up to five consecutive Index Business Days on which a Market Disruption Event is occurring, but not past the Index Business Day prior to maturity.

An Index Business Day means a day, as determined by the calculation agent, on which the S&P MidCap 400^® Index or any successor index is calculated and published and on which securities comprising more than 80% of the value of the S&P MidCap 400^® Index on such day are capable of being traded on their relevant exchanges or markets during the one-half hour before the determination of the closing value of the S&P MidCap 400^® Index. All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will be conclusive for all purposes and binding on us, Citigroup and the beneficial owners of the Notes, absent manifest error.

A Market Disruption Event means, as determined by the calculation agent in its sole discretion, the occurrence or existence of any suspension of or limitation imposed on trading (by reason of movements in price exceeding limits permitted by any relevant exchange or market or otherwise) of, or the unavailability, through a recognized system of public dissemination of transaction information, for a period longer than two hours, or during the one-half hour period preceding the close of trading, on the applicable exchange or market, of accurate price, volume or related information in respect of (a) stocks which then comprise 20% or more of the value of the S&P MidCap 400^® Index or any successor index, (b) any options or futures contracts, or any options on such futures contracts relating to the S&P MidCap 400^® Index or any successor index, or (c) any options or futures contracts relating to stocks which then comprise 20% or more of the value of the S&P MidCap 400^® Index or any successor index on any exchange or market if, in each case, in the determination of the calculation agent, any such suspension, limitation or unavailability is material. For the purpose of

PS-11

determining whether a Market Disruption Event exists at any time, if trading in a security included in the S&P MidCap 400^® Index is materially suspended or materially limited at that time, then the relevant percentage contribution of that security to the value of the S&P MidCap 400^® Index will be based on a comparison of the portion of the value of the S&P MidCap 400^® Index attributable to that security relative to the overall value of the S&P MidCap 400^® Index, in each case immediately before that suspension or limitation.

Hypothetical Returns at Maturity

The Note Return Amount will depend on the closing value of the S&P MidCap 400^® Index on every Index Business Day from the Pricing Date up to and including the Valuation Date and on the Ending Value of the S&P MidCap 400^® Index. Because the closing value of the S&P MidCap 400^® Index may be subject to significant variations over the term of the Notes, it is not possible to present a chart or table illustrating a complete range of possible payments at maturity. The examples of hypothetical maturity payments set forth below are intended to illustrate the effect of different Ending Values of the S&P MidCap 400^® Index on the return on the Notes at maturity, depending on whether the closing value of the S&P MidCap 400^® Index on every Index Business Day from the Pricing Date up to and including the Valuation Date is both less than or equal to approximately 133% of the Starting Value and greater than or equal to approximately 80% of the Starting Value. All of the hypothetical examples assume an investment in the Notes of $10, that the Starting Value is 800.00, that 133% of the Starting Value is 1,064.00, that 80% of the Starting Value is 640.00, that the term of the Notes is 2 years, and that an investment is made on the initial issue date and held to maturity.

As demonstrated by the examples below, if the hypothetical closing value of the S&P MidCap 400^® Index on every Index Business Day from the Pricing Date up to and including the Valuation Date is both less than or equal to 1,064.00 and greater than or equal to 640.00 the return will be equal to the Absolute Index Return Percentage and, so long as the hypothetical Ending Value does not equal the hypothetical Starting Value, the payment at maturity will be greater than the initial investment of $10 per Note. If, however, the hypothetical closing value of the S&P MidCap 400^® Index on any Index Business Day from the Pricing Date up to and including the Valuation Date is greater than 1,064.00 or less than 640.00, the return on the Notes will be zero, regardless of whether the hypothetical Ending Value is greater than or less than the hypothetical Starting Value.

(1)	The hypothetical value of the S&P MidCap 400® Index on every Index Business Day from the Pricing Date up to and including the Valuation Date has been less than or equal to 1,064.00, which is 133% of the hypothetical Starting Value, and greater than or equal to 640.00, which is 80% of the hypothetical Starting Value.
(2)	The hypothetical value of the S&P MidCap 400® Index on any Index Business Day from the Pricing Date up to and including the Valuation Date has been greater than 1,064.00, which is 133% of the hypothetical Starting Value, or less than 640.00, which is 80% of the hypothetical Starting Value.

PS-13

The examples are for purposes of illustration only. The actual Note Return Amount will depend on the actual Starting Value, the actual closing values of the S&P MidCap 400^® Index during the term of the Notes, the Ending Value, and other relevant parameters.

Discontinuance of the S&P MidCap 400^® Index

If S&P discontinues publication of the S&P MidCap 400^® Index or another entity publishes a successor or substitute index that the calculation agent determines, in its sole discretion, to be comparable to the S&P MidCap 400^® Index, then the value of the S&P MidCap 400^® Index will be determined by reference to the value of that index, which we refer to as a “successor index.”

Upon any selection by the calculation agent of a successor index, the calculation agent will cause notice to be furnished to us and the trustee, who will provide notice of the selection of the successor index to the registered holders of the Notes.

If S&P discontinues publication of the S&P MidCap 400^® Index and a successor index is not selected by the calculation agent or is no longer published on any date of determination of the value of the S&P MidCap 400^® Index, the value to be substituted for the S&P MidCap 400^® Index for that date will be a value computed by the calculation agent for that date in accordance with the procedures last used to calculate the relevant index prior to any such discontinuance.

If S&P discontinues publication of the S&P MidCap 400^® Index prior to the determination of the Note Return Amount and the calculation agent determines that no successor index is available at that time, then on each Index Business Day until the earlier to occur of (a) the determination of the Note Return Amount and (b) a determination by the calculation agent that a successor index is available, the calculation agent will determine the value that is to be used in computing the value of the S&P MidCap 400^® Index or the relevant index as described in the preceding paragraph.

If a successor index is selected or the calculation agent calculates a value as a substitute for the relevant index as described above, the successor index or value will be substituted for the relevant index for all purposes, including for purposes of determining whether an Index Business Day or Market Disruption Event occurs.

Notwithstanding these alternative arrangements, discontinuance of the publication of the S&P MidCap 400^® Index may adversely affect the market value of the Notes. All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will be conclusive for all purposes and binding on us, Citigroup Inc. and the beneficial owners of the Notes, absent manifest error.

Alteration of Method of Calculation

If at any time the method of calculating the S&P MidCap 400^® Index or a successor index is changed in any material respect, or if the S&P MidCap 400^® Index or a successor index is in any other way modified so that the value of the S&P MidCap 400^® Index or the successor index does not, in the opinion of the calculation agent, fairly represent the value of that index had the changes or modifications not been made, then, from and after that time, the calculation agent will, at the close of business in New York, New York, make those adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a calculation of a value of a stock index comparable to the S&P MidCap 400^® Index or the successor index as if the changes or modifications had not been made, and calculate the value of the index with reference to the S&P MidCap 400^® Index or the successor index. Accordingly, if the method of calculating the S&P MidCap 400^® Index or the successor index is modified so that the value of the S&P MidCap 400^® Index or the successor index is a fraction or a multiple of what it would have been if it had not been modified, then the calculation agent will adjust that index in order to arrive at a value of the index as if it had not been modified.

PS-14

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.”

Events of Default and Acceleration

In case an Event of Default (as defined in the accompanying prospectus) with respect to any Note shall have occurred and be continuing, the amount declared due and payable upon any acceleration of the Notes will be determined by the calculation agent and will equal, for each Note, the payment at maturity, calculated as though the maturity of the Notes were the date of early repayment. See “— Payment at Maturity” above. If a bankruptcy proceeding is commenced in respect of Citigroup Funding or Citigroup Inc., the claim of the beneficial owner a Note will be capped at the maturity payment, calculated as though the maturity date of the Notes were the date of the commencement of the proceeding.

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 4.75% per annum on the unpaid amount due.

Paying Agent and Trustee

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

Calculation Agent

The calculation agent for the Notes will be Citigroup Global Markets. 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 also 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 the holders of the Notes. Citigroup Global Markets is obligated to carry out its duties and functions as calculation agent in good faith and using its reasonable judgment.

PS-15

DESCRIPTION OF THE S&P MidCap 400^® INDEX

General

Unless otherwise stated, all information on the S&P MidCap 400^® Index provided in this pricing supplement is derived from S&P or other publicly available sources. The S&P MidCap 400^® Index is published by S&P and is intended to provide a performance benchmark for the medium capitalization segment of the U.S. equity markets. It tracks the stock price movement of 400 companies with mid-sized market capitalizations, primarily ranging from $1.5 billion to $5.5 billion.

As of June 30, 2008, the companies making up the S&P MidCap 400 Index had an aggregate adjusted market capitalization of approximately $1,051.22 billion. The aggregate market value of the 400 companies included in the S&P MidCap 400^® Index represented approximately 7% of the aggregate market value of the U.S. equities market. The largest five sectors represented by the S&P MidCap 400 Index with the percentage of all sectors covered by the index indicated in parentheses were: Financials (14.71%), Information Technology (14.63%), Industrials (17.21%), Consumer Discretionary (11.70%) and Energy (11.03%).

THE S&P MIDCAP 400 INDEX DOES NOT REFLECT THE PAYMENT OF DIVIDENDS ON THE STOCKS UNDERLYING IT AND THEREFORE THE RETURN ON THE NOTES WILL NOT PRODUCE THE SAME RETURN YOU WOULD RECEIVE IF YOU WERE TO PURCHASE SUCH UNDERLYING STOCKS AND HOLD THEM UNTIL THE MATURITY DATE.

Computation of the S&P MidCap 400^® Index

The calculation of the value of the S&P MidCap 400^® Index is based on the relative value of the aggregate S&P MidCap 400 Market Value of the common stocks of 400 companies (the “S&P MidCap 400 Component Stocks”) as of a particular time as compared to the aggregate average S&P MidCap 400^® Market Value of the common stocks of 400 similar companies during the base period of June 28, 1991. The “S&P MidCap 400^® Market Value” of any S&P MidCap 400^® Component Stock is the product of the market price per share and the number of the then outstanding shares of such S&P MidCap 400^® Component Stock. S&P chooses companies for inclusion in the S&P MidCap 400^® Index with an aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the medium capitalization segment of the U.S. equity market. S&P may from time to time, in its sole discretion, add companies to, or delete companies from, the S&P MidCap 400^® Index to achieve the objectives stated above. Relevant criteria employed by S&P include U.S. company status, market capitalization in the range of $1.5 billion to $5.5 billion, financial viability, a public float of at least 50%, adequate liquidity and reasonable price, sector representation and status as an operating company, the extent to which that company represents the industry group to which it is assigned, the extent to which the company’s common stock is widely held and the S&P MidCap 400^® Market Value and trading activity of the common stock of that company.

The S&P MidCap 400 Index is calculated using a base-weighted aggregate methodology: the level of the S&P MidCap 400^® Index reflects the total S&P MidCap 400^® Market Value of all 400 Component Stocks relative to the S&P MidCap 400^® Index’s base period of June 28, 1991 (the “S&P MidCap 400^® Base Period”). An indexed number is used to represent the results of this calculation in order to make the value easier to work with and track over time.

The actual total S&P MidCap 400^® Market Value of the S&P MidCap 400^® Component Stocks during the S&P MidCap 400^® Base Period has been set equal to an indexed value of 100. This is often indicated by the notation June 28, 1991=100. In practice, the daily calculation of the S&P MidCap 400^® Index is computed by dividing the total S&P MidCap 400 Market Value of the S&P MidCap 400^® Component Stocks by a number called the S&P MidCap 400^® Index Divisor. By itself, the S&P MidCap 400^® Index Divisor is an arbitrary number. However, in the context of the calculation of the S&P MidCap 400^® Index, it is the only link to the original base period value of the S&P MidCap 400^® Index. The S&P MidCap 400^® Index Divisor keeps the S&P MidCap 400^® Index comparable over time and is the manipulation point for all adjustments to the S&P MidCap 400 Index (“S&P MidCap 400^® Index Maintenance”).

PS-16

Historically, the market value of any underlying stocks included in the S&P MidCap 400^® Index was calculated as the product of the market price per share and the number of the then outstanding shares of that underlying stock. In March 2005, S&P began shifting the S&P MidCap 400^® Index half way from a market capitalization weighted formula to a float-adjusted formula, before moving the S&P MidCap 400^® Index to full float adjustment on September 16, 2005. S&P’s criteria for selecting stocks for the S&P MidCap 400^® Index did not change by the shift to float adjustment. However, the adjustment affects each company’s weight in the S&P MidCap 400^® Index (i.e., its market value).

Under float adjustment, the share counts used in calculating the S&P MidCap 400^® Index reflect only those shares that are available to investors, not all of a company’s outstanding shares. Standard and Poor’s defines three groups of shareholders whose holdings are subject to float adjustment:

•  holdings by other publicly traded corporations, venture capital firms, private equity firms, strategic partners, or leveraged buyout groups;

•  holdings by government entities, including all levels of government in the United States or foreign countries; and

•  holdings by current or former officers and directors of the company, founders of the company, or family trusts of officers, directors, or founders, as well as holdings of trusts, foundations, pension funds, employee stock ownership plans, or other investment vehicles associated with and controlled by the company.

However, treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. In cases where holdings in a group exceed 10% of the outstanding shares of a company, the holdings of that group are excluded from the float-adjusted count of shares to be used in the index calculation. Shares held by mutual funds, investment advisory firms, pension funds, or foundations not associated with the company and investment funds in insurance companies, shares of a United States company traded in Canada as “exchangeable shares”, shares that trust beneficiaries may buy or sell without difficulty or significant additional expense beyond typical brokerage fees, and, if a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class if such shares are convertible by shareholders without undue delay and cost, are also part of the float.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares, defined as the total shares outstanding less shares held in one or more of the three groups listed above where the group holdings exceed 10% of the outstanding shares, by the total shares outstanding. The float-adjusted index is then calculated by dividing the sum of the IWF multiplied by both the price and the total shares outstanding for each stock by the index divisor. For companies with multiple classes of stock, S&P calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

Maintenance of the S&P MidCap 400^® Index

S&P MidCap 400 Index Maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spin-offs.

To prevent the value of the S&P MidCap 400^® Index from changing due to corporate actions, all corporate actions that affect the total S&P MidCap 400^® Market Value of the S&P MidCap 400^® Index require an S&P MidCap 400^® Index Divisor adjustment. By adjusting the S&P MidCap 400^® Index Divisor for the change in total S&P MidCap 400^® Market Value, the value of the S&P MidCap 400^® Index remains constant. This helps maintain the value of the S&P MidCap 400^® Index as an accurate barometer of stock market performance and ensures that the movement of the S&P MidCap 400^® Index does not reflect the corporate actions of individual companies in the S&P MidCap 400^® Index. All S&P MidCap 400^® Index Divisor adjustments are made after the close of trading and after the calculation of the closing value of the S&P MidCap 400^® Index. Some corporate actions, such as stock splits and stock dividends, require simple changes

PS-17

in the common shares outstanding and the stock prices of the companies in the S&P MidCap 400^® Index and do not require S&P MidCap 400^® Index Divisor adjustments.

The table below summarizes the types of S&P MidCap 400^® Index maintenance adjustments and indicates whether or not an S&P MidCap 400^® Index Divisor adjustment is required.

		Divisor Adjustment
Type of Corporate Action	S&P Adjustment Factor	Required
Stock split (i.e., 2x1)	Shares Outstanding times 2; Stock Price divided by 2	No
Share issuance (i.e., Change > 5)%	Shares Outstanding plus newly issued Shares	Yes
Share repurchase (i.e., Change > 5)%	Shares Outstanding minus Repurchased Shares	Yes
Special cash dividends	Share Price minus Special Dividend	Yes
Company change	Add new company Market Value minus old company Market Value	Yes
Rights offering	Price of parent company minus Price of Rights (Right Ratio)	Yes
Spin-offs	Price of parent company minus Price of Spin-off Co. (Share Exchange Ratio)	Yes

Stock splits and stock dividends do not affect the S&P MidCap 400^® Index Divisor of the S&P MidCap 400^® Index, because following a split or dividend both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the S&P MidCap 400^® Market Value of the S&P MidCap 400^® Component Stock. All stock split and dividend adjustments are made after the close of trading on the day before the ex-dividend date.

Each of the corporate events exemplified in the table requiring an adjustment to the S&P MidCap 400^® Index Divisor has the effect of altering the S&P MidCap 400^® Market Value of the S&P MidCap 400^® Component Stock and consequently of altering the aggregate S&P MidCap 400^® Market Value of the S&P MidCap 400^® Component Stocks (the “Post-Event Aggregate S&P MidCap 400^® Market Value”). In order that the level of the S&P MidCap 400^® Index (the “Pre-Event S&P MidCap 400^® Index Value”) not be affected by the altered S&P MidCap 400^® Market Value (whether increase or decrease) of the affected S&P MidCap 400^® Component Stock, a new S&P MidCap 400^® Index Divisor (“S&P MidCap 400^® New Divisor”) is derived as follows:

Post − Event Aggregate Market Value
New Divisor = Pre − Event Index Value                      

                      New Divisor = Post − Event Aggregate Market Value Pre − Event Index Value

A large part of the S&P MidCap 400^® Index maintenance process involves tracking the changes in the number of shares outstanding of each of the S&P MidCap 400^® Index companies. Four times a year, on a Friday near the end of each calendar quarter, the share totals of companies in the S&P MidCap 400^® Index are updated as required by any changes in the number of shares outstanding. After the totals are updated, the S&P MidCap 400^® Index Divisor is adjusted to compensate for the net change in the total S&P MidCap 400^® Market Value of the S&P MidCap 400^® Index. In addition, any changes over 5% in the current common shares outstanding for the S&P MidCap 400^® Index companies are carefully reviewed on a weekly basis, and when appropriate, an immediate adjustment is made to the S&P MidCap 400^® Index Divisor.

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”). 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 Contingent Debt Regulations. The remainder of this summary assumes the treatment of each Note as a single debt instrument subject to the Contingent Debt Regulations and the holder’s agreement thereto.

United States Holders

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 4.4503%, 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$10.9337 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

PS-21

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$10 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$0.1520 in 2008; US$0.4568 in 2009; and US$0.3248 in 2010 (adjusted as described below).

Adjustments to Interest Accruals on the Notes.  If, during any taxable year, a U.S. Holder receives actual payments with respect to the Notes that in the aggregate exceed the total amount of projected payments for that taxable year, the U.S. Holder will incur a “net positive adjustment” under the Contingent Debt Regulations equal to the amount of such excess. The U.S. Holder will treat a “net positive adjustment” as additional interest income, which will increase the total amount of Tax OID for that taxable year. Accordingly, the amount of taxable income that a U.S. Holder may be required to report with respect to the Note for a particular year may exceed both the amount of Tax OID and the actual cash payments received.

If a U.S. Holder receives in a taxable year actual payments with respect to the Notes that in the aggregate are less than the amount of projected payments for that taxable year, the U.S. Holder will incur a “net negative adjustment” under the Contingent Debt Regulations equal to the amount of such deficit. This adjustment will reduce the U.S. Holder’s interest income on the Notes for that taxable year, which will decrease the total amount of Tax OID for that taxable year. Accordingly, the amount of taxable income that a U.S. Holder may be required to report with respect to the Note for a particular year may differ significantly both from the amount of Tax OID and the actual cash payments received.

If the S&P MidCap 400^® Index is greater than 1,096.07 (approximately 134.50% of the Starting Value) or is less than 651.94 (approximately 80% of the Starting Value) (the “Index Threshold Prices”) at any time before six months prior to maturity of the Notes, so that the amount paid at the maturity of the Notes would become fixed, then a U.S. Holder would incur a ”net negative adjustment” to interest income under the CPDI regulations. The amount of the adjustment would be equal to the difference between the present value of the amount of the fixed payment at maturity and the present value of the projected amount of the payment at maturity, in each case determined by discounting the amount from the maturity date to the date when either of the Index Threshold Prices is met, using a discount rate equal to the comparable yield on the Notes. Under the CPDI regulations, those adjustments must be taken into account in a reasonable manner over the periods to which they relate. As a result, such an adjustment should be recognized over the remaining term of the Notes as a decrease to interest accruals.

U.S. Holders should be aware that the information statements they receive from their brokers (on an Internal Revenue Service Form 1099) stating accrued original issue discount in respect of the Notes may not take net negative or positive adjustments into account, and thus may overstate or understate the holders’ interest inclusions.

Disposition of the Notes.  When a U.S. Holder sells, exchanges, or otherwise disposes of a Note (including upon repayment of the Note at maturity) (a “disposition”), the U.S. Holder generally will recognize gain or loss on such disposition equal to the difference between the amount received by the U.S. Holder for the Note net of any accrued but unpaid interest, which will be treated as such, and the U.S. Holder’s tax basis in the Note. A U.S. Holder’s tax basis in a Note generally will be equal to the U.S. Holder’s original purchase

PS-22

price for such Note, plus any Tax OID accrued by the U.S. Holder (determined without regard to any adjustments to interest accruals described above) and less the amount of any projected payments received by the holder according to the projected payment schedule while holding the Note (without regard to the actual amount paid). Any gain realized by a U.S. Holder on a disposition of a Note generally will be treated as ordinary interest income. Any loss realized by a U.S. Holder on a disposition generally 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. However, if either of the Index Threshold Prices is met more than six months prior to the maturity of the Notes, then any gain or loss arising from a subsequent disposition of the Notes will be capital.

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 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. The deductibility of net capital losses is subject to limitations.

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 gain are not effectively connected with the conduct by such Non-U.S. Holder of 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 a 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.

PS-23

Information Reporting and Backup Withholding.  In general, a Non-U.S. Holder generally 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.

U.S. Federal Estate Tax.  A Note beneficially owned by a Non-U.S. Holder who at the time of death is neither a resident nor citizen of the U.S. should not be subject to U.S. federal estate tax.
