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

The Strategic Market Access Notes based upon the Citi Country Selection Index (the “Notes”) are securities offering no principal protection. The amount you receive at maturity or upon your exercise of the Monthly Early Redemption Option described below is based on the performance of the Citi Country Selection Index (“CCSI”), may be less than your initial investment in the notes and could be zero.

The CCSI is an equity index consisting of five country-specific total return indices selected on a monthly basis from a fixed universe of 22 country-specific total return indices — the Morgan Stanley Capital International Inc. (“MSCI”) Daily Total Return Net Indices for each of Australia, Austria, Belgium, Brazil, Canada, France, Germany, Hong Kong, Italy, Japan, Malaysia, Mexico, the Netherlands, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan and the United Kingdom (collectively, the “MSCI Daily Total Return Net Indices”) and the Standard & Poor’s^® 500 Total Return Index (the “S&P 500^® Total Return Index”) for the United States (collectively, the “Underlying Total Return Indices”). Each month the CCSI is rebalanced, and reconstituted, if required, through the application of a preset methodology (the “Methodology”) that attempts to determine the five countries with equity markets that may be able to outperform the global equity market during the succeeding month, though there is no guarantee of results. Once the five countries are identified, the corresponding five Underlying Total Return Indices are initially weighted equally to comprise the CCSI for that month. The amount you receive at maturity or upon your exercise of the Monthly Early Redemption Option is primarily determined by the index return of the CCSI as reflected in the Notes’ Net Investment Value. Some key characteristics of the Notes include:


--	No Principal Protection. The Notes are not principal protected. The amount you receive at maturity or upon your exercise of the Monthly Early Redemption Option may be less than your initial investment in the Notes and could be zero.

--	No Periodic Payments. The Notes do not offer current income, which means that you will not receive any payments on the Notes prior to maturity or your exercise of the Monthly Early Redemption Option. You will also not receive any dividend payments or other distributions, if any, made on the stocks included in the Underlying Total Return Indices.


--	No Exchange Listing. The Notes will not be listed on any exchange. While the Chicago Board Options Exchange (“CBOE”) will publish the value of the CCSI and the Net Investment Value of the Notes on a daily basis, this is informational only and does not create any secondary market for the Notes. Although Citigroup Global Markets intends to make a secondary market for the Notes, it is not obligated to do so.

--	Monthly Early Redemption Option. On any Index Business Day during the last five calendar days of each month (a “Monthly Redemption Period”) beginning approximately three months after the issue date of the Notes, each holder of the Notes may redeem a minimum of 1,000 Notes ($10,000 aggregate principal amount) for cash in an amount equal to the Net Investment Value of the Notes on the second Index Business Day immediately following the last calendar day of such Monthly Redemption Period minus a Redemption Fee of 0.25% of such Net Investment Value.

--	Net Investment Value. The Net Investment Value of the Notes on the Pricing Date will be $9.725 per Note. On any Index Business Day thereafter, the Net Investment Value per Note will equal $9.725 multiplied by the Index Return Percentage. Because the Net Investment Value per Note is determined by multiplying the Index Return Percentage by $9.725, not $10, only 97.25% of your initial investment in the Notes will participate in the appreciation, if any, of the CCSI. At maturity or upon early redemption, you will receive less than the principal amount you invested unless the value of the CCSI on the relevant Index Business Day is greater than its closing value on the Pricing Date by more than 2.8% (plus the Redemption Fee, if applicable). The daily Net Investment Value of the Notes will be published by the CBOE under the symbol “CJH.”

--	Adjustment Factors. The value of the CCSI is calculated after the deduction of two types of adjustment factors: (i) an Index Adjustment Factor of 1.25% per annum based upon the arithmetic average of the daily closing values of the CCSI on each Index Business Day of any month and (ii) Country Adjustment Factors, if applicable, which will vary depending upon which countries are added or deleted from the CCSI in any month. The deduction of these adjustment factors will reduce the value of the CCSI and therefore, the return on your Notes.

The Notes are a series of unsecured senior debt securities issued by Citigroup Funding, the payments on which 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 payments due under the Notes will rank equally with all other unsecured and unsubordinated debt of Citigroup Inc.


--	Investors with positive return expectations for the CCSI who are willing to risk principal

--	Investors looking for international equity exposure to diversify an existing equity portfolio

--	Current or prospective holders of an exchange-traded fund benchmarked to the Underlying Total Return Indices then-comprising the CCSI

Benefits of the Notes


--	Growth Potential. The Net Investment Value payable at maturity or upon your exercise of the Monthly Early Redemption Option, if any, is primarily based on the Index Return Percentage, enabling you to participate in the increase, if any, in the value of the CCSI during the term of the Notes.

--	Diversification Potential. The Notes are linked to the CCSI, which consists of five equity indices representing five different countries and may allow you to diversify an existing equity portfolio through exposure to international stocks.

--	Monthly Early Redemption Option. If you do not wish to hold your Notes to maturity, you can redeem your Notes on any Index Business Day during a Monthly Redemption Period, beginning approximately three months after the Issue Date of the Notes, for cash in an amount equal to the Net Investment Value of the Notes on the Redemption Valuation Date minus a Redemption Fee of 0.25% of such Net Investment Value. To timely exercise the Monthly Early Redemption Option, you must (1) redeem a minimum of 1,000 Notes; (2) fill out an official notice of redemption, which is attached as Annex A to the preliminary pricing supplement related to this offering; (3) deliver your official notice of redemption to us (which must be acknowledged by us) on any Index Business Day in a Monthly Redemption Period but at or prior to 12:00 p.m. (New York City time) on the last Index Business Day in that Monthly Redemption Period; and (4) transfer your book- entry interest in the Notes to the trustee on our behalf at or prior to 10:00 a.m. (New York City time) on the fifth Payment Day following the Redemption Valuation Date.

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


--	Potential for Loss. The amount payable at maturity or upon your exercise of the Monthly Early Redemption Option, if any, will depend on the Net Investment Value of the Notes on the Final Valuation Date or the relevant Redemption Valuation Date, respectively. As a result, the amount you receive at maturity or upon early redemption may be less than the amount you paid for your Notes. If the closing value of the CCSI declines, remains the same or does not increase by more than 2.8% (plus the Redemption Fee, if applicable) from the Starting Index Value, so that the Net Investment Value per Note on the relevant date is less than $10 per Note, the amount you receive for each Note will be less than the $10 you paid for each Note. This will be true even if the closing value of the CCSI at one or more times during the term of the Notes exceeds the Starting Index Value.

--	The Return on Your Notes Will Be Reduced. Because the Net Investment Value per Note is determined by multiplying the Index Return Percentage by $9.725, not $10, only 97.25% of your initial investment in the Notes will participate in the appreciation, if any, of the CCSI. Moreover, upon your exercise of the Monthly Early Redemption Option a Redemption Fee of 0.25% of the Net Investment Value will be deducted from the redemption payment, if any, further reducing your return on the Notes. The value of the CCSI must increase by more than 2.8% (plus the Redemption Fee, if applicable) for the amount payable at maturity or upon early redemption, if any, to be greater than your initial investment in the Notes.


--	No Periodic Payments. The Notes do not offer current income, which means that you will not receive any payments on the Notes prior to maturity or your exercise of the Monthly Early Redemption Option. You will also not receive any dividend payments or other distributions, if any, made on the stocks included in the Underlying Total Return Indices.

--	Limitations on the Monthly Early Redemption Option. If you elect to exercise your Monthly Early Redemption Option, you must offer to redeem at least 1,000 Notes ($10,000 aggregate principal amount) at one time during a Monthly Redemption Period. To redeem your Notes during any Monthly Redemption Period, you must instruct your broker to take the steps outlined in “Preliminary Terms — Early Redemption Process” above. If you provide your official notice of redemption after 12:00 p.m. (New York City time) on the last Index Business Day in a Monthly Redemption Period, your notice will not be effective and you will need to again complete all the required steps if you wish to redeem your Notes during a subsequent Monthly Redemption Period.

--	The Return on the CCSI May Be Lower than the Return of an Index Based Upon a Different Combination of Underlying Total Return Indices. The five Underlying Total Return Indices comprising the CCSI each month will be selected solely on the basis of the results of the Methodology. There is no guarantee that this combination of five Underlying Total Return Indices will actually perform better than a different combination of Underlying Total Return Indices. This may cause your return on the Notes, if any, to be less than the return on an index linked to a different combination of the Underlying Total Return Indices.

--	The Return on the CCSI May Be Lower than the Return on One or More of the Underlying Total Return Indices. Because the value of the CCSI will be based on the returns of the Underlying Total Return Indices comprising the CCSI, a significant increase in the value of one of the indices during the term of the Notes but not the other indices may be substantially or entirely offset by a decrease in the value of the other 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 Total Return Indices.

--	The Return on the CCSI May Be Lower Than an Index With More Geographic Diversification. While the CCSI will be comprised of five of the 22 Underlying Total Return Indices each month, the five Underlying Total Return Indices in any month may be geographically concentrated. Such lack of diversification may cause the value of the CCSI to be more volatile and/or cause the return on the Notes, if any, to be less than the return on a similar instrument linked to more a geographically diverse index.

--	The Preset Methodology Will Not Be Altered During the Term of the Notes. The 21 MSCI Daily Total Return Net Indices do not represent all of the currently-published MSCI Daily Total Return Net Indices nor do they represent the full global equity market. Similarly, the Methodology on which the CCSI is based evaluates the 22 countries represented by the Underlying Total Return Indices on the basis of only 17 economic factors. Any other economic factors, political events or other market developments will not be reflected in the computation of the Methodology or in the calculation of the CCSI, except to the extent such factor, event or development impacts the 17 preset factors. Because the 22 countries and 17 factors in the Methodology are fixed and will not be altered during the term of the Notes, the value of the CCSI may be less than the value of an index that takes new factors or equity indices of additional countries into account.


--	Potential for a Lower Comparative Yield. The Notes do not pay any interest. As a result, if the Net Investment Value of the Notes on the Final Valuation Date or the relevant Redemption Valuation Date is less than %, the effective yield on the Notes will be less than that which would be payable on a conventional fixed-rate, non-callable debt security of Citigroup Funding of comparable maturity.

--	Exchange Listing and Secondary Market. The Notes will not be listed on any exchange. While Citigroup Global Markets intends to make a secondary market for the Notes, it is not obligated to do so. Even if a secondary market does develop, it may not be liquid and may not continue for the term of the Notes. If the secondary market for the Notes is limited, there may be few buyers should you choose to sell your Notes prior to maturity and this may reduce the price you receive. Additionally, the value of the CCSI will be published by the CBOE only once a day. There will be no intra-day values for the CCSI since the equity markets represented by several of the Underlying Total Return Indices may be closed during New York trading hours.

--	The Tax Characterization of Some of the Potential Gains Is Uncertain. 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, including the tax consequences associated with the amount attributable to dividends and other current returns in respect of the Underlying Total Return Indices. No ruling is being requested from the Internal Revenue Service with respect to the Notes and no assurance can be given that the Internal Revenue Service will agree with the conclusions expressed under “Certain United States Federal Income Tax Considerations” in the preliminary pricing supplement related to this offering.

--	The Resale Value of the Notes May be Lower Than Your Initial Investment. Due to, among other things, changes in the value of the CCSI, the Net Investment Value of the Notes, currency exchange rates, the performance of the stocks included in the Underlying Total Return 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 $10 per Note. You could receive substantially less than the amount of your initial investment if you sell your Notes prior to maturity.

--	Investments in or Related to Emerging Markets are Subject to Greater Risks than those in More Developed Markets. All of the MSCI Daily Total Return Net Indices are comprised of stocks from foreign markets, many of which are considered emerging markets. Investments in or related to emerging markets are subject to a greater risk of loss than those in more developed markets due to economic, political and social instability.

--	The Stocks Included in the MSCI Daily Total Return Net Indices Will Be Affected by Conditions in Foreign Securities Markets. All of the stocks that constitute the MSCI Daily Total Return Net Indices 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 MSCI Daily Total Return Net 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 MSCI Daily Total Return Net Indices may be limited by price limitations on, or suspensions of trading of, individual stocks


	constituting the MSCI Daily Total Return Net Indices, which may, in turn, adversely affect the value of the CCSI and the Notes.

--	The Values of the MSCI Daily Total Return Net Indices are Subject to Currency Exchange Rate Risk. Because the value of the CCSI is denominated and calculated in U.S. dollars and the value of each of the MSCI Daily Total Return Net Indices is denominated and calculated in a currency other than U.S. dollars, the value of the CCSI will be exposed to currency exchange risk. Your net exposure to this risk will depend on the extent to which these foreign currencies strengthen or weaken against the U.S. dollar and the relative weight of each MSCI Daily Total Return Net Index then-comprising the CCSI. If, taking into account such weighting, the U.S. dollar strengthens against these other currencies, the value of the MSCI Daily Total Return Net Indices will be adversely affected and the value of the CCSI will decline.

--	Fees and Conflicts. Citigroup Global Markets Inc. 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 shares of exchange-traded funds based on the Underlying Total Return Indices (“ETF shares”) and/or the stocks included in the Underlying Total Return Indices, or other instruments, such as options, swaps or futures, based upon the CCSI, each of the Underlying Total Return Indices, the ETF shares or the stocks included in the Underlying Total Return 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.

--	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.

General. The CBOE began calculating and publishing the daily value of the Citi Country Selection Index under the symbol “CTH” on October 12, 2007, with an initial value of 100 as of June 7, 2004. The CCSI is based on the Methodology, developed by the Citigroup Global Quantitative Research Team (the “Methodology Sponsor”) and launched on June 7, 2004.

The CCSI is an equity index consisting of five country-specific total return indices selected on a monthly basis from 22 country-specific total return indices — the MSCI Daily Total Return Net Indices for each of Australia, Austria, Belgium, Brazil, Canada, France, Germany, Hong Kong, Italy, Japan, Malaysia, Mexico, the Netherlands, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan and the United Kingdom and the S&P 500^® Total Return Index for the United States. Each month the CCSI is rebalanced, and reconstituted, if required, through the application of the Methodology. You should refer to “Description of the Citi Country Selection Model” in the preliminary pricing supplement related to this offering for a detailed description of the Methodology, including its method of calculation and changes in its components.

Description of the Methodology. The Methodology attempts to determine five countries with equity markets that may be able to out-perform the global equity market during the succeeding month, though there is no guarantee of results. Once the five countries are identified, the corresponding five Underlying Total Return Indices are initially weighted equally to comprise the CCSI for that month.

The Methodology starts with a fixed universe of 22 countries, each having an equity market represented by one of the Underlying Total Return Indices, and 17 formulaic, economic factors that are analyzed to identify the five potential country out-performers. The universe of 22 countries and 17 factors are fixed and will not change during the term of the Notes.

The application of the Methodology requires formulaic analyses of data with respect to each of the 22 countries through a process summarized by the following three phases:


--	data retrieval;

--	for each of the 22 countries, identification of top 5 of the 17 factors, through the application of the Methodology, determined to be the most relevant in explaining the equity out- performance of such country;

--	determination of a country score for each of the 22 countries and the selection of the corresponding top five Underlying Total Return Indices to comprise the CCSI.

Monthly Rebalancing and Reconstitution (if required) of the CCSI. On the fifth Index Rebalancing Day of each month, the CBOE will rebalance and reconstitute the CCSI based upon the five countries to be included in the CCSI for such month as determined by the Methodology Sponsor. The CBOE will remove the Underlying Total Return Index of any country no longer to be included in the CCSI and will add the Underlying Total Return Index of any country newly included in the CCSI. The CBOE will then deduct the applicable Country Adjustment Factors, if any, from the value of the CCSI. All calculations will be based upon the closing level of each of the Underlying Total Return Indices (whether being removed or added) as of the fifth Index Rebalancing Day of each month. Regardless of whether the countries comprising the CCSI have changed, the CBOE will also rebalance the CCSI on the fifth Index Rebalancing Day of each month, based upon the closing value of each of the Underlying Total Return on that day, so that the values of each of the Underlying Total Return Indices then-comprising the CCSI are equally weighted and each contribute 20% to the value of the CCSI.

An Index Rebalancing Day is a day, as determined by the calculation agent, on which (i) all data required for the computation of 17 factors for each of the 22 countries are published or otherwise readily available, and the CCSI or any successor index is calculated and published, and (ii) securities comprising more than 80% of the value of each of the Underlying Total Return Indices then-comprising or to be added to the CCSI is capable of being traded on their relevant exchanges or markets during the one-half hour before the determination of the closing value of such Underlying Total Return Indices. 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.

CCSI Adjustment Factors. Two types of adjustment factors will be applied to the return of the CCSI. First, an Index Adjustment Factor of 1.25% per annum will be deducted from the value of the CCSI. The amount of the Index Adjustment Factor each month will be calculated and deducted from the value of CCSI on the first Index Business Day of each month by multiplying (i) the Index Adjustment Factor of 1.25% per annum and (ii) the product of (x) the arithmetic average of the closing values of the CCSI on every Index Business Day in the immediately preceding month and (y) a fraction, the numerator of which is the actual number of calendar days in that month and the denominator of which is 365.

Second, Country Adjustment Factors will be deducted from the value of the CCSI on the fifth Index Rebalancing Day in any month where the country composition of the CCSI is changed. When a country is removed from the CCSI (as represented by the removal of its corresponding Underlying Total Return Index), the applicable Country Adjustment Factor will be applied to the value of the CCSI represented by the value of each Underlying Total Return Index removed. When a country is added to the CCSI (as represented by the addition of its corresponding Underlying Total Return Index), the applicable Country Adjustment Factor will be applied to 20% of the value of the CCSI for each Underlying Total Return Index removed. The table below lists the Country Adjustment Factor applicable to each of the 22 countries:

Both types of adjustment factors will remain unchanged throughout the term of the Notes.

You should refer to the preliminary pricing supplement related to this offering for additional information on the Underlying Total Return Indices, including their respective methods of calculation and changes in components. All such disclosures on the Underlying Total Return Indices in the preliminary pricing supplement are derived from publicly available information. None of Citigroup Funding, Citigroup Inc., Citigroup Global Markets or the trustee assumes any responsibility for the accuracy or completeness of such information.

Hypothetical and Actual Historical Closing Values Graph. The CBOE began calculating and publishing the value of the CCSI under the symbol “CTH” on October 12, 2007, with an initial value of 100 as of June 7, 2004. The following graph sets forth the hypothetical historical closing values of the CCSI on each Index Business Day commencing on June 7, 2004 and ending on October 12, 2007. The graph also sets forth the actual closing values of the CCSI on each Index Business Day commencing on October 12, 2007 and ending on October 19, 2007.

Actual historical results of the Methodology were used to calculate the hypothetical historical closing values of the CCSI. However, these hypothetical historical closing values should not be taken as an indication of the actual composition of the CCSI or the future performance of the CCSI. Any hypothetical historical upward or downward trend in the value of the CCSI during any period set forth below is not an indication that the CCSI is more or less likely to increase or decrease at any time during the term of the Notes. The hypothetical historical closing values set forth below have not been reviewed or verified by MSCI or S&P.

License Agreements. MSCI and Citigroup Global Markets, an affiliate of Citigroup Funding, have entered into a non-exclusive license agreement providing for the license to Citigroup Global Markets and its affiliates, in exchange for a fee, of the right to use indices owned and published by MSCI in connection with certain financial instruments, including the Notes.

The examples of hypothetical amounts received at maturity or upon early redemption set forth below are intended to illustrate the effect of different closing values of the CCSI on the amount you will receive in respect of the Notes upon your exercise of the Monthly Early Redemption Option or at maturity. All of the hypothetical examples are based on the following assumptions:

The following examples are for purposes of illustration only and would provide different results if different assumptions were applied. The actual amount you receive upon your exercise of the Monthly Early Redemption Option will depend on the Net Investment Value on the relevant Redemption Valuation Date, minus the Redemption Fee, while the actual amount you receive at maturity (if not earlier redeemed) will depend on the Net Investment Value on the Final Valuation Date.

(1)	The Hypothetical Index Return Percentage equals the following fraction, expressed as a percentage:


(2)	The Hypothetical Maturity Payment per Note equals the Hypothetical Net Investment Value per Note: $9.725 multiplied by the Hypothetical Index Return Percentage.

(3)	The Hypothetical Amount received per Note Upon Exercise of the Early Redemption Option equals the Hypothetical Net Investment Value per Note minus a Redemption Fee equal to 0.25% of the Net Investment Value of the Note.

The following summarizes certain federal income tax considerations for U.S. investors that are initial holders of the Notes and that hold the Notes as capital assets. A “U.S. Holder” is defined to mean a person that is (i) an individual citizen or resident of the United States, (ii) a corporation organized in or under the laws of the United States or any state thereof or the District of Columbia or (iii) otherwise subject to U.S. federal income taxation on a net income basis in respect of the Notes.

For U.S. federal income tax purposes, we intend to treat the Notes as a cash-settled prepaid forward contract providing for a future payment based on the value of the Underlying Index at maturity under which an amount equal to the purchase price of the Notes is treated as a non-interest-bearing cash deposit to be applied at maturity in full satisfaction of the holder’s payment obligation under the prepaid forward contract. Under such treatment, a holder’s tax basis in a Note generally will equal the holder’s cost for that Note, and a holder who is a U.S. Holder generally will recognize gain or loss upon the sale or other taxable disposition of a Note equal to the difference between the amount realized on the sale or other taxable disposition and the holder’s tax basis in the Notes. Such gain or loss generally will be long-term capital gain or loss if the holder has held the Notes for more than one year at the time of disposition. Under the above characterization, at maturity a holder who is a U.S. Holder will recognize capital gain or loss equal to any difference between the amount of cash received from Citigroup Funding and the holder’s tax basis in the Notes at that time. Such gain or loss generally will be long-term gain or loss if the holder has held the Notes for more than one year at maturity.

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, including the tax consequences associated with the amount attributable to dividends and other current returns in respect of the underlying indices. 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. 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:


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

	2.	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.

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 the Notes by the account, plan or annuity.
