Buffer Notes

Based Upon a Global Index Basket Due June 2, 2011

This Offering Summary represents a summary of the terms and conditions of the Notes. We encourage you to read the pricing supplement and accompanying prospectus supplement and prospectus related to this offering. Capitalized terms used in this overview are defined in the “Final Terms” below.

OVERVIEW OF THE NOTES

The Buffer Notes Based Upon a Global Index Basket due 2011 (the “Notes”), are index-linked investments that offer a potential return at maturity based on an enhanced upside participation in any increase in the value of the Global Index Basket during the term of the Notes, while also providing full protection against a decline of 20% or less in the value of the Global Index Basket and limited protection against a decline of more than 20% in the value of the Global Index Basket. The Notes are not principal protected and do not pay periodic interest. The return on the Notes, if any, is based upon a basket comprised of four equity indices: the S&P 500^® Index, the Dow Jones EURO STOXX 50^® Index, the Nikkei 225 Stock Average^SM and the Hang Seng China Enterprises Index (each, an “Underlying Index” and together, the “Global Index Basket”). In the calculation of the return on the Global Index Basket, the return on the S&P 500^® Index, the Dow Jones EURO STOXX 50^® Index and the Nikkei 225 Stock Average^SM will each be weighted 30% and the return on the Hang Seng China Enterprises Index will be weighted 10%. The Notes have a maturity of approximately 3.5 years and are issued by Citigroup Funding Inc. Some key characteristics of the Notes include:

^O Limited Downside Protection and Enhanced Upside Participation. At maturity you will receive for each Note you hold a maturity payment based on the percentage change in the value of the Global Index Basket from the Pricing Date to the Valuation Date, which may be greater than, equal to, or less than your initial investment in the Notes. We refer to the percentage change in the closing value of the Global Index Basket from the Pricing Date to the Valuation Date as the Basket Return. If the Ending Value of the Global Index Basket is greater than its Starting Value of 100, at maturity you will receive for each Note you then hold the $1,000 principal amount per Note plus 115% of the Basket Return. If the Ending Value of the Global Index Basket is less than or equal to 100 but greater than or equal to 80, the maturity payment will equal the $1,000 principal amount per Note. If the Ending Value of the Global Index Basket is less than 80 (representing a decrease of more than 20% from its Starting Value of 100), the maturity payment will equal the $1,000 principal amount per Note plus the product of (i) $1,000 and (ii) the sum of (1) the Basket Return (which will be negative) and (2) 20%. Thus, if the Ending Value of the Global Index Basket is less than 80, the maturity payment will be less than your initial investment of $1,000 per Note and your investment in the Notes will result in a loss. However, in no case will the maturity payment equal less than 20% of your investment in the Notes.

^O No Periodic Payments. The Notes do not offer current income, which means that you will not receive any periodic interest on the Notes. You will also not receive any dividend payments or other distributions, if any, made on the stocks included in the Underlying Indices.

^O No Principal Protection. While the Notes provide limited protection against the decline in the value of the Global Index Basket, the Notes are not principal protected. If the closing value of the Global Index Basket is less than 80 (a decrease of more than 20% from its Starting Value of 100), the maturity payment you will receive will equal $1,000 principal amount per Note plus the product of (i) the $1,000 principal amount per Note and (ii) the sum of (1) the Basket Return (which will be negative) and (2) 20%. Thus, if the Ending Value of the Global Index Basket is less than 80, the maturity payment will be less than your initial investment in the Notes and your investment in the Notes will result in a loss.

2

The Notes are a series of unsecured senior debt securities issued by Citigroup Funding. Any payments due on the Notes are fully and unconditionally guaranteed by Citigroup Inc., Citigroup Funding’s parent company. The Notes will rank equally with all other unsecured and unsubordinated debt of Citigroup Funding, and as a result of the guarantee any payments due under the Notes at maturity will rank equally with all other unsecured and unsubordinated debt of Citigroup Inc. The return of the principal amount of your investment in the Notes at maturity is not guaranteed.

TYPES OF INVESTORS

The Notes may be an attractive investment for the following types of investors:

^O Investors looking for potential enhanced upside exposure to the Global Index Basket

^O Investors willing to accept downside exposure to the Global Index Basket with limited protection

^O Investors who seek to add an equity index-linked investment to further diversify their portfolio

^O Current or prospective holders of exchange-traded funds and index funds benchmarked to any of the Underlying Indices that comprise the Global Index Basket who are willing to accept the downside risk in the Global Index Basket, subject to limited protection against loss

BENEFITS OF THE NOTES

^O Enhanced Participation in any Appreciation of the Global Index Basket.    The return on the Notes, if any, is based upon the performance of the Global Index Basket. If the Ending Value of the Global Index Basket exceeds its Starting Value, your participation in the basket’s appreciation will be increased by the Upside Participation Rate.

^O Some Protection Against Loss.    At maturity you will receive your original investment in the Notes even if the Ending Value of the Global Index Basket has declined from its Starting Value, as long as the Ending Value is not less than 80% of the Starting Value. In this case, you will not suffer the same loss that a direct investment in the Underlying Indices would produce. However, if the Ending Value of the Global Index Basket is less than 80 (a decline of more than 20% from its Starting Value), the amount you receive at maturity will be less than your initial investment in the Notes.

^O Diversification.    The Notes are linked to the Global Index Basket and may allow you to diversify an existing portfolio mix of stocks, bonds, mutual funds and cash.

KEY RISK FACTORS FOR THE NOTES

An investment in the Notes involves significant risks. While some of the risk considerations are summarized below, please review the “Risk Factors Relating to the Notes” section of the pricing supplement related to this offering and the “Risk Factors” section of the accompanying prospectus supplement for a full description of risks.

^O Potential for Loss.    The Notes are not principal protected. The maturity payment on the Notes will depend on the percentage change in the value of the Global Index Basket from the Pricing Date to the Valuation Date. If the Ending Value of the Global Index Basket is less than 80 (a decrease of more than 20% from its Starting Value of 100), the maturity payment you will receive will be less than your original investment in the Notes and your investment in the Notes will result in a loss. This will be true even if the closing value of the Global Index Basket exceeded its Starting Value at one or more times over the term of the Notes.

^O No Periodic Payments.    You will not receive any periodic payments of interest 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 Underlying Indices.

^O Potential for a Lower Comparative Yield.    Because you will not receive any periodic payments of interest or any other periodic payments on the Notes, if the Ending Value of the Global Index Basket does not increase sufficiently from its Starting Value, taking into account the Upside Participation Rate, the effective yield on the Notes may be less than that which would be payable on a conventional fixed-rate debt security of Citigroup Funding of comparable maturity.

^O Exchange Listing and Secondary Market.    The Notes will not be listed on any exchange. There is currently no secondary market for the Notes. Even if a secondary market does develop, it may not be liquid and may not continue for the term of the Notes. Although Citigroup Global Markets intends to make a secondary market for the Notes, it is not obligated to do so.

^O Return on the Global Index Basket May Be Lower than the Return on One or More of the Underlying Indices.    Because the value of the Global Index Basket will be based on the weighted returns of the Underlying Indices, a significant increase in the value of one of the Underlying Indices during the term of the Notes but not the other Underlying Indices may be substantially or entirely offset by a decrease in the value of one or more of the other underlying Indices during the term of the Notes. This may cause your return on the Notes, if any, to be less than the return on a similar instrument linked to one or more of the Underlying Indices.

^O Resale Value of the Notes May Be Lower Than Your Initial Investment.    Due to, among other things, changes in the prices of and dividend yields on the stocks included in the Underlying Indices, interest rates, the earnings performance of the issuers of the stocks included in the Underlying Indices, correlation among the four Underlying Indices, other economic conditions and Citigroup Funding and Citigroup Inc.’s perceived creditworthiness, the Notes may trade at prices below their initial issue price of $1,000 per Note. You could receive substantially less than the amount of your initial investment if you sell your Notes prior to maturity.

5

^O Some of the Stocks Included in the Global Index Basket Will Be Affected by Conditions in Foreign Securities Markets.    Some of the stocks that constitute the Global Index Basket have been issued by companies in foreign securities markets. Securities prices in foreign markets are subject to political, economic, financial and social factors that apply in those markets. Foreign securities markets may be more volatile than U.S. securities markets and may be affected by market developments in different ways than U.S. securities markets. In addition, certain of the exchanges on which the stocks constituting the Underlying Indices are traded may have adopted certain measures intended to limit short-term price fluctuations. These may include daily price floors and ceilings intended to prevent extreme fluctuations in individual stock prices. As a result, variations in the value of the Underlying Indices may be limited by price limitations on, or suspensions of trading of, individual stocks constituting the Underlying Indices, which may, in turn, adversely affect the value of the Global Index Basket and the Notes.

^O Fees and Conflicts.    Citigroup Global Markets and its affiliates involved in this offering are expected to receive compensation for activities and services provided in connection with the Notes. Further, Citigroup Funding expects to hedge its obligations under the Notes through the trading of the stocks included in the Underlying Indices or other instruments, such as options, swaps or futures, based upon the Global Index Basket, the Underlying Indices or the stocks included in the Underlying Indices, by one or more of its affiliates. Each of Citigroup Funding’s or its affiliates’ hedging activities and Citigroup Global Markets’ role as the Calculation Agent for the Notes may result in a conflict of interest.

^O Citigroup Inc. Credit Risk.    The Notes are subject to the credit risk of Citigroup Inc., Citigroup Funding’s parent company and the guarantor of any payments due on the Notes.

Certain U.S. Federal Income Tax Considerations

The following summarizes certain federal income tax considerations for U.S. investors (“U.S. Holders”) and certain non-U.S. investors described below that are initial holders of the Notes and that hold the Notes as capital assets

For U.S. federal income tax purposes, the Notes generally should be treated as a variable cash-settled prepaid forward contract, subject to a floor, on the value of the Global Index Basket on the Valuation Date, pursuant to which forward contract, at maturity the U.S. Holder will receive the cash value of the Global Index Basket subject to certain adjustments. The amounts invested by a U.S. Holder should be treated as a cash deposit that will be used to satisfy the holder’s obligation under the Note. Thus a U.S. Holder’s tax basis in a Note generally will equal the holder’s cost for that Note. Under the above characterization, at maturity or upon the sale or other taxable disposition of a Note, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount the U.S. Holder receives and the holder’s tax basis in the Notes. Such gain or loss generally will be long-term capital gain or loss if the U.S. Holder has held the Notes for more than one year at the time of disposition.

No statutory, judicial or administrative authority directly addresses the characterization of the Notes or instruments similar to the Notes for U.S. federal income tax purposes. As a result, significant aspects of the U.S. federal income tax consequences of an investment in the Notes are not certain. Accordingly, a prospective investor (including a tax-exempt investor) in the Notes should consult his or her tax advisor in determining the tax consequences of an investment in the Notes, including the application of State, Local or other tax laws and the possible effects of changes in Federal or other tax laws.

In the case of a holder of a Note that is not a U.S. person (“Non-U.S. Holder”) the payments made with respect to the Notes will not be subject to U.S. withholding tax, provided that the holder complies with applicable certification requirements (including in general the furnishing of an IRS form W-8 or substitute form). Any capital gain realized upon the sale or other disposition of the Notes should not be subject to U.S. federal income tax if:

^O such gain is not effectively connected with a U.S. trade or business of such holder, and

^O in the case of an individual, such individual is not present in the United States for 183 days or more in the taxable year of the sale or other disposition or the gain is not attributable to a fixed place of business maintained by such individual in the United States.

You should refer to the pricing supplement related to this offering for additional information relating to U.S. federal income tax and should consult your own tax advisors to determine tax consequences particular to your situation.

Description of the Global Index Basket

General. The Global Index Basket will be established on the Pricing Date and will be calculated by Citigroup Global Markets, as calculation agent. The Global Index Basket will represent the weighted returns of the following four equity indices from the Pricing Date to the Valuation Date: the S&P 500^® Index, the Dow Jones EURO STOXX 50^® Index, the Nikkei 225 Stock Average^SM and the Hang Seng China Enterprises Index. Each of the four indices included in the Global Index Basket will initially be weighted as set forth below based on the value of each index on the Pricing Date, as determined by the calculation agent, to achieve a Starting Value of 100 for the Global Index Basket on that date:

Underlying Index	Initial Percentage of Basket	Initial Index Value	Basket Composition Ratio
S&P 500® Index	30%	1,469.02	0.020422
Dow Jones EURO STOXX 50® Index	30%	4,321.74	0.006942
Nikkei 225 Stock AverageSM	30%	15,153.78	0.001980
Hang Seng China Enterprises Index	10%	27,371.24	0.000365

The value of the Global Index Basket on the Pricing Date, will equal the sum of the products of (i) each Underlying Index’s closing level on the Pricing Date (the “Initial Index Value”) and (ii) that Underlying Index’s Basket Composition Ratio. The value of the Global Index Basket on the Valuation Date will equal (i) the sum of the products of each Underlying Index’s closing level on the Valuation Date and (ii) that Underlying Index’s Basket Composition Ratio. The Basket Composition Ratio for the S&P 500^® Index will equal 30.00 divided by the closing level of the S&P 500^® Index on the Pricing Date. The Basket Composition Ratio for the Dow Jones EURO STOXX 50^® Index will equal 30.00 divided by the closing level of the Dow Jones EURO STOXX 50^® Index on the Pricing Date. The Basket Composition Ratio for the Nikkei 225 Stock Average^SM will equal 30.00 divided by the closing level of the Nikkei 225 Stock Average^SM on the Pricing Date. The Basket Composition Ratio for the Hang Seng China Enterprises Index will equal 10.00 divided by the closing level of the Hang Seng China Enterprises Index on the Pricing Date. The value of the Global Index Basket on the Valuation Date, will equal the sum of the products of (i) each Underlying Index’s closing level on the Valuation Date and (ii) that Underlying Index’s Basket Composition Ratio. The value of the Global Index Basket will not be published by any exchange.

The following graph sets forth the hypothetical historical closing values of the Global Index Basket on each index business day, commencing January 1, 2002 through November 28, 2007. Each value was calculated as if the Global Index Basket had been created on January 1, 2002 with an initial value of 100. The Global Index Basket will actually be established on the Pricing Date with a value of 100. The hypothetical historical closing values set forth below in the graph have not been reviewed or verified by Dow Jones & Company, Inc. (“Dow Jones”), STOXX Limited (“STOXX”), Nihon Keizai Shimbun, Inc. (“NKS”), Standard & Poor’s (“S&P”), Hang Seng Data Services Limited or any other independent third party.

Actual historical closing values of each of the four Underlying Indices were used to calculate the hypothetical historical closing values of the Global Index Basket. However, these hypothetical historical closing values should not be taken as an indication of the actual composition of the Global Index Basket on the Pricing Date or the future performance of the Global Index Basket or what the market value of the Notes may be. Any hypothetical historical upward or downward trend in the value of the Global Index Basket during any period set forth below is not an indication that the Global Index Basket is more or less likely to increase or decrease at any time during the term of the Notes.

The source of the data on each of the Underlying Indices used to compute the hypothetical historical closing values of the Global Index Basket is Bloomberg.

Additional information on the Global Index Basket and each Underlying Index, including its respective makeup, method of calculation and changes in its components, is included in the pricing supplement related to this offering under “Description of the Global Index Basket,” “Description of the S&P 500^® Index,” “Description of the Dow Jones EURO STOXX 50^® Index,” “Description of the Nikkei 225 Stock Average^SM” and “Description of the Hang Seng China Enterprises Index.” All such disclosures in the pricing supplement are derived from publicly available information. None of Citigroup Funding, Citigroup Inc., or Citigroup Global Markets assumes any responsibility for the accuracy or completeness of such information. You should also be aware 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 Underlying Indices.

ERISA and IRA Purchase Considerations

Employee benefit plans subject to ERISA, entities the assets of which are deemed to constitute the assets of such plans, governmental or other plans subject to laws substantially similar to ERISA and retirement accounts (including Keogh, SEP and SIMPLE plans, individual retirement accounts and individual retirement annuities) are permitted to purchase the Notes as long as either (A)(1) no Citigroup Global Markets affiliate or employee is a fiduciary to such plan or retirement account that has or exercises any discretionary authority or control with respect to the assets of such plan or retirement account used to purchase the Notes or renders investment advice with respect to those assets and (2) such plan or retirement account 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.

You should refer to the section “ERISA Matters” in the pricing supplement related to this offering for more information.

Additional Considerations

In addition, if any of the Underlying Indices is discontinued, the Calculation Agent may determine the Ending Value by reference to a successor index or, if no successor index is available, in accordance with the procedures last used to calculate the relevant index prior to any such discontinuance. You should refer to the sections “Description of the Notes—Basket Return Amount” and “—Discontinuance of any Underlying Index” in the pricing supplement for more information.
