ELKS^® Based Upon the American Depository Shares Representing the Ordinary Shares of Barclays PLC Due November 23, 2011

Equity Linked Securities (“ELKS^®”)

ELKS offer a short-term, enhanced yield strategy that pays a periodic, above-market, fixed rate coupon (per annum) in return for the risk that the ELKS will redeem for a fixed number of American Depository Receipts (“ADRs”) of the underlying equity (or, at your option, the cash value of those ADRs) at maturity if the closing price of the underlying equity is less than or equal to the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date. The value of these ADRs may be less than the stated principal amount of the investor’s initial investment and could be zero, and, except in limited circumstances, the investor has no opportunity to participate in any increase in the price of the underlying equity. Alternatively, if the closing price of the underlying equity never declines to or below the downside threshold closing price from but excluding the pricing date to and including the valuation date, the ELKS will return the stated principal amount at maturity. The coupon is paid regardless of the performance of the underlying equity. Payment at maturity may be less than the stated principal amount of your investment in the ELKS. The ELKS are a series of unsecured senior debt securities issued by Citigroup Funding. Any payments due on the ELKS are fully and unconditionally guaranteed by Citigroup Inc., Citigroup Funding’s parent company. All payments on the ELKS are subject to the credit risk of Citigroup Inc.

Payment at maturity may be less than the stated principal amount of your investment in the ELKS.

We make no representation that the publicly available information about Barclays is accurate or complete. The ELKS represent obligations of Citigroup Funding only. Barclays is not involved in any way in this offering and has no obligation relating to the ELKS or to holders of the ELKS.

Key Investment Information

The ELKS offer a short-term income oriented strategy linked to the underlying equity.

■ A coupon per annum which is higher than the current dividend yield on the underlying equity.

■ Except in limited circumstances, no potential to participate in any appreciation of the underlying equity.

■ Payment at maturity may be less than the stated principal amount of your investment in the ELKS.

The ELKS pay an above-market coupon and offer contingent protection against declines in the underlying equity in exchange for the risk that you receive ADRs of the underlying equity worth less than the stated principal amount at maturity. If the closing price of the underlying equity has declined to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date, the amount you receive at maturity may be less than the stated principal amount of your initial investment in the ELKS and could be zero. Payment at maturity may be less than the stated principal amount of your investment in the ELKS.

Citigroup Funding Inc.

ELKS Based on the American Depository Shares Representing the Ordinary Shares of Barclays PLC Due November 23, 2011

Equity Linked Securities ("ELKS^®")

Enhanced Yield

■ A monthly coupon, with a per annum rate that is higher than the current dividend yield on the underlying equity.

■ The monthly coupon will be paid regardless of the performance of the underlying equity.

Best Case Scenarios

■ If the closing price of the underlying equity never declines to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date, the ELKS will redeem at maturity, for the stated principal amount, resulting in a total return on a per annum basis equal to the coupon. You will not participate in any appreciation in the underlying equity, even if the closing price of the underlying equity on the valuation date is above the initial equity price.

■ Alternatively, in limited circumstances, if the closing price of the underlying equity declines to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date, and, on the maturity date (or on the valuation date if you elect to receive the cash value of the equity ratio) the closing price of the underlying equity is greater than the initial equity price, the ELKS will redeem for a number of ADRs of the underlying equity (or, at your option, the cash value of those ADRs based on the closing price of the underlying equity on the valuation date) worth more than the stated principal amount.

Worst Case Scenario

■ If the closing price of the underlying equity declines to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date and, on the maturity date (or on the valuation date if you elect to receive the cash value of the shares at the equity ratio), the closing price of the underlying equity is at a level substantially below the initial equity price, the ELKS will redeem for a number of shares of the underlying equity (or, at your option, the cash value of those shares based on the closing price of the underlying equity on the valuation date) worth substantially less than the stated principal amount and which may be worth zero. In this worst case scenario, the ELKS will have outperformed the underlying equity on a per annum basis by the difference between the coupon and any dividends paid on the underlying equity.

Summary of Selected Key Risks (see page 10)

■ No guaranteed return of principal.

■ Except in limited circumstances, the ELKS will not provide investors with any appreciation in the underlying equity.

■ The ELKS are subject to the credit risk of Citigroup Inc., Citigroup Funding’s parent company and the guarantor of any payments due on the ELKS, and any actual or anticipated changes to its credit ratings or credit spreads may adversely affect the market value of the ELKS.

■ Under particular circumstances, the return on your investment in the ELKS may be less than the amount that would be paid on conventional debt securities issued by us (and guaranteed by Citigroup Inc.) with similar maturities.

■ Secondary trading may be limited, and the inclusion of underwriting fees and projected profit from hedging in the issue price is likely to adversely affect secondary market prices.

■ The U.S. federal income tax consequences of an investment in the ELKS are uncertain.

■ The market price of the underlying equity is influenced by many unpredictable factors.

■ The volatility of the price of the underlying equity may result in your receiving an amount at maturity that is less than the stated principal amount of the ELKS and that could be zero.

■ Investors in the ELKS will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying equity.

■ The calculation agent, which is an affiliate of the issuer, will make determinations with respect to the ELKS.

■ There are important differences between the rights of the holders of the ADRs representing ordinary shares of Barclays PLC and the rights of holders of ordinary shares of Barclays PLC.

■ Citigroup Investment Research or other affiliates of Citigroup Funding may publish research reports or commentary that may influence the price of Barclays ADRs and, therefore, the value of the ELKS.

■ Citigroup Funding or its affiliates may engage in business with or involving the underlying equity issuer without regard to your interests.

General Information
Listing:	The ELKS will not be listed on any securities exchange.
CUSIP:	17317U204
ISIN:	US17317U2042
Tax considerations:	The U.S. federal income tax consequences of an investment in the ELKS are uncertain. There is no direct legal authority as to the proper tax treatment of the ELKS, and the issuer’s counsel has not rendered an opinion as to their proper treatment for U.S. federal income tax purposes. Pursuant to the terms of the ELKS and subject to the discussion in the accompanying ELKS product supplement under “Certain United States Federal Income Tax Considerations,” you agree with the issuer to treat an ELKS, under current law, as an option on a forward contract, pursuant to which forward contract, at maturity you will purchase ADRs of the underlying equity (or the cash equivalent). In addition, you and Citigroup Funding agree to treat the amount invested by you as a cash deposit that will be used to satisfy your purchase obligation. Assuming the characterization of the ELKS as set forth above is respected, a portion of the coupon on the ELKS will be treated as the yield on the deposit, and the remainder will be attributable to the option premium, as described below and in the section of the accompanying ELKS product supplement. Of the total coupon payable on the ELKS, approximately 3% (to be determined on the pricing date) will be characterized as the interest component and approximately 97% (to be determined on the pricing date) will be characterized as the option premium component. You will be required to include any interest component as interest income at the time that such interest is accrued or received in accordance with your method of accounting. You will not be required to include option premium received in income until sale or other taxable disposition of the ELKS or retirement of the ELKS. If you hold the ELKS until they mature, if you receive cash at maturity, you will recognize short-term capital gain or loss equal to the difference between (x) the sum of cash received at maturity and the entire option premium (but not including any interest component), and (y) your purchase price for the ELKS. If you receive ADRs of the underlying equity upon the retirement of the ELKS, subject to the discussion below, you should not expect to recognize any gain or loss on the receipt of the ADRs of the underlying equity, and your tax basis in the ADRs of the underlying equity generally will equal your purchase price for the ELKS less the amount of the entire option premium. On December 7, 2007, the Treasury Department and the Internal Revenue Service (the "IRS") released a notice requesting comments on the U.S. federal income tax treatment of "prepaid forward contracts" and similar instruments. While it is not entirely clear whether the ELKS would be viewed as similar to the prepaid forward contracts described in the notice, it is possible that any Treasury regulations or other guidance issued after consideration of these issues could materially and adversely affect the tax consequences of an investment in the ELKS, possibly with retroactive effect. The notice focuses on a number of issues, the most relevant of which for holders of the ELKS are the character and timing of income or loss (including whether the option premium should be required to be included currently as ordinary income) and the degree, if any, to which income realized

	by non-U.S. investors should be subject to withholding tax. Non-U.S. Holders should note that we currently do not intend to withhold on any payments made with respect to the ELKS to Non-U.S. Holders (subject to compliance by such holders with certification requirements necessary to establish an exemption from withholding). However, in the event of a change of law or any formal or informal guidance by the IRS, Treasury or Congress, we may decide to withhold on payments made with respect to the ELKS to Non-U.S. Holders, and we will not be required to pay any additional amounts with respect to amounts withheld. Both U.S. and non-U.S. investors considering an investment in the ELKS should read the discussion under "Risk Factors – Structure Specific Risk Factors" in this offering summary and the discussion under "Certain United States Federal Income Tax Considerations" in the accompanying ELKS product supplement and consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the ELKS, including possible alternative treatments, the issues presented by the aforementioned notice, any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction, and the possible effects of changes in Federal or other tax laws.
Trustee:	The Bank of New York Mellon
Calculation agent:	Citigroup Global Markets Inc.
Use of proceeds and hedging:	The net proceeds we receive from the sale of the ELKS will be used for general corporate purposes and, in part, in connection with hedging our obligations under the ELKS through one or more of our affiliates. On, or prior to, the pricing date, we, through our affiliates or others, will hedge our anticipated exposure in connection with the ELKS by taking positions in the underlying equity, in options contracts on the underlying equity listed on major securities markets, or positions in any other available securities or instruments that we may wish to use in connection with such hedging. Such purchase activity could increase the price of the underlying equity, and, accordingly, potentially increase the initial equity price and the downside threshold price of the ELKS, and, therefore, the price at which the underlying equity must trade on each trading day from but excluding the pricing date to and including the valuation date before you would receive for each ELKS at maturity an amount of cash or ADRs of the underlying equity worth as much as the stated principal amount of the ELKS. For further information on our use of proceeds and hedging, see "Can You Tell Me More About the Effect of Citigroup Funding’s Hedging Activity?" in the accompanying ELKS product supplement.
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 ELKS as long as either (A) (1) no Citigroup Global Markets affiliate, employee or affiliate’s 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 ELKS 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 ELKS or (B) its acquisition and holding of the ELKS 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 ELKS if the account, plan or annuity is for the benefit of an employee of Citigroup Global Markets or Morgan Stanley Smith Barney LLC or a family member and the employee receives any compensation (such as, for example, an addition to bonus) based on the purchase of ELKS by the account, plan or annuity. You should refer to the section "ERISA Matters" in the accompanying ELKS product supplement for more information.

Equity Linked Securities ("ELKS^®")

How ELKS Work

The following payment scenarios illustrate the potential payments on the ELKS at maturity.

Payment Scenario 1

The closing price of the underlying equity never falls to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date, and you receive the monthly coupon at maturity with a full return of principal at maturity. You will not participate in any appreciation of the underlying equity, even if the closing price of the underlying equity is above the initial equity price on the valuation date.

Payment Scenario 2

The closing price of the underlying equity falls to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date, in which case, at maturity, the ELKS redeem for ADRs of the underlying equity (or, at your option, the cash value of those ADRs based on the closing price of the underlying equity on the valuation date). If you do not elect to receive cash, you will be deemed to have (1) instructed Citigroup Funding to pay the cash value of the number of underlying ADRs equal to the equity ratio to the stock delivery agent, and (2) instructed the stock delivery agent to purchase for you underlying ADRs based on its closing price on the valuation date. Citigroup Global Markets has agreed to act as stock delivery agent for the ELKS. The value of the underlying equity on the maturity date (or on the valuation date if you elect to receive the cash value of the equity ratio) may be less than, greater than or equal to the stated principal amount of the ELKS. You will receive the monthly coupon at maturity in any event.

Hypothetical Payments on the ELKS

The following examples illustrate the payment at maturity on the ELKS, assuming a 6-month term, for a range of hypothetical closing prices for the underlying equity on the maturity date, depending on whether on any trading day from but excluding the pricing date to and including the valuation date, the closing price of the underlying equity has or has not decreased to or below the downside threshold closing price.

The hypothetical examples are based on the following hypothetical values and assumptions in order to illustrate how ELKS work (and do not reflect the actual initial equity price of the underlying equity, equity ratio, downside threshold closing price or coupon per annum of the ELKS):

Stated principal amount (per ELKS):	$10.00
Initial equity price:	$20.00 (the hypothetical closing price of one ADR of the underlying equity on the pricing date)
Equity ratio:	0.50000 (the $10.00 stated principal amount per ELKS divided by the hypothetical initial equity price)
Downside threshold closing price:	$16.00 (80.00% of the hypothetical initial equity price)
Coupon per annum:	9.00%
Annualized dividend yield:	3.25%
Maturity Date:	6 months after the issue date

The closing price of the underlying equity on the valuation date is the same as the closing price on the maturity date.

TABLE 1: At maturity, unless the closing price of the underlying equity has decreased to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date, your payment at maturity per ELKS will equal the stated principal amount of the ELKS in cash. This table represents the hypothetical payment at maturity and the total payment over the term of the ELKS (assuming a 6-month term) on a $10.00 investment in the ELKS on the basis that the closing price of the underlying equity has not decreased to or below the hypothetical downside threshold closing price of $16.00 on any trading day from but excluding the pricing date to and including the valuation date.

TABLE 2: This table represents the hypothetical payment at maturity and the total payment over the term of the ELKS (assuming a 6-month term) on a $10.00 investment in the ELKS if the closing price of the underlying equity has decreased to or below the hypothetical downside threshold closing price of $16.00 on any trading day from but excluding the pricing date to and including the valuation date. In each of these examples, the payment at maturity would be made by delivery of ADRs of the underlying equity (or, at your option, the cash value of those ADRs based on the closing price of the underlying equity on the valuation date). The value of such ADRs may be less than, greater than or equal to the stated principal amount of the ELKS.

* Assumes dividends not compounded and not reinvested.

Because the closing price of the underlying equity may be subject to significant fluctuation over the term of the ELKS, it is not possible to present a chart or table illustrating the complete range of possible payouts at maturity. The examples of the hypothetical payout calculations above are intended to illustrate how the amount payable to you at maturity will depend on whether the closing price of the underlying equity falls to or below the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date.

Equity Linked Securities ("ELKS^®")

Risk Factors

The ELKS offered by this offering summary are financial instruments that are suitable only for investors who are capable of understanding the complexities and risks specific to the ELKS. Accordingly, investors should consult their own financial and legal advisers as to the risks entailed by an investment in the ELKS and the suitability of the ELKS in light of an investor’s particular circumstances.

The following is a non-exhaustive list of certain key risk factors for investors in the ELKS. For a complete list of risk factors, you should read "Risk Factors Relating to the ELKS” in the accompanying ELKS product supplement and “Risk Factors" in the related prospectus supplement.

Structure Specific Risk Factors

str

■ You may not receive a return of principal. The payment to investors at maturity will either be (1) a fixed number of ADRs of the underlying equity equal to the equity ratio (or, if you exercise your cash election right, the cash value of those ADRs based on the closing price of the underlying equity on the valuation date) if the closing price of the underlying equity on any trading day from but excluding the pricing date to and including the valuation date declines to or below the downside threshold closing price, or (2) $10 in cash. If, at maturity, investors receive ADRs of the underlying equity, or the cash value of those ADRs based on the closing price of the underlying equity on the valuation date, in exchange for the ELKS, the value of those ADRs or the cash may be less than the stated principal amount of the ELKS and could be zero. See "How ELKS Work" on page 8.

■ Market price influenced by many unpredictable factors. Several factors will influence the value of the ELKS in the secondary market. Although the issuer expects that generally the closing prices of the underlying equity on any day will affect the value of the ELKS more than any other single factor, other factors that may influence the value of the ELKS include: whether the closing price of the underlying equity has decreased to or below the downside threshold closing price on any trading day, the volatility and dividend rate on the underlying equity, geopolitical conditions and economic, financial, political, regulatory or judicial events, interest and yield rates in the market, the time remaining to the maturity of the ELKS, any actual or anticipated changes in the credit ratings or credit spreads of Citigroup Inc., and the occurrence of certain events affecting the underlying equity that may or may not require an adjustment to the equity ratio.

■ Volatility of the price of the underlying equity. Volatility is the term used to describe the size and frequency of market fluctuations in the price of the underlying equity. Because the amount of your return on the ELKS at maturity, if any, depends upon the closing price of the underlying equity from but excluding the pricing date to and including the valuation date and may be based on the closing price of the underlying equity at maturity (or on the valuation date if you elect to receive the cash value of the equity ratio), the volatility of the price of the underlying equity may result in your receiving an amount at maturity that is less than the stated principal amount of the ELKS and that could be zero. Although the past level of price volatility is not indicative of future price volatility, see "Information About the Underlying Equity — Historical Information" and "— Barclays PLC Common Stock Closing Prices January 02, 2006 to April 25, 2011" in this offering summary for more information on the historical prices of ADRs of the underlying equity.

■ The ELKS are subject to the credit risk of Citigroup Inc. and any actual or anticipated changes in its credit ratings or credit spreads may adversely affect the market value of the ELKS. Investors are dependent on the ability of Citigroup Inc., Citigroup Funding’s parent company and the guarantor of any payments due on the ELKS, to pay all amounts due on the ELKS on interest payment dates and at maturity, and, therefore, investors are subject to the credit risk of Citigroup Inc. and to changes in the market’s view of Citigroup Inc.’s creditworthiness. Any decline, or anticipated decline, in Citigroup Inc.’s credit ratings or increase, or anticipated increase, in the credit spreads charged by the market for taking Citigroup Inc.’s credit risk is likely to adversely affect the market value of the ELKS.

■ Appreciation only in limited circumstances. You will not participate in any appreciation in the price of the underlying equity, and the return on the ELKS will be limited to the coupon payable on the ELKS, unless (i) the closing price of the underlying equity on any trading day from but excluding the pricing date to and including the valuation date declines from the initial equity price to be less than or equal to the downside threshold closing price and (ii) the closing price of the underlying equity at maturity (or on the valuation date if you elect to receive the cash value of the equity ratio) is greater than the initial equity price. Therefore, the return on the ELKS may be less than the return on a similar security that allows you to participate more fully in the appreciation of the price of the underlying equity, or on a direct investment in the underlying equity, if the price of the underlying equity at maturity (or on the valuation date, as applicable) is significantly greater than the initial equity price but you do not receive ADRs of the underlying equity (or the cash value of those ADRs) at maturity because the closing price of the underlying equity has never fallen to or below the downside threshold closing price.

■ Potential for a lower comparative yield. If the closing price of the underlying equity is less than or equal to the downside threshold closing price on any trading day from but excluding the pricing date to and including the valuation date and the closing price of the underlying equity at maturity (or on the valuation date if you elect to receive the cash value of the equity ratio) is less than approximately $Spa (resulting in your receiving a total amount at maturity that is less than the stated principal amount of your ELKS), the effective yield on the ELKS may be less than that which would be payable on a conventional fixed-rate debt security of Citigroup Funding (guaranteed by Citigroup Inc.) with a comparable maturity.

Equity Linked Securities ("ELKS^®")

■ We may engage in business with or involving the underlying equity issuer without regard to your interests. We or our affiliates may presently or from time to time engage in business with the underlying equity issuer without regard to your interests, including extending loans to, or making equity investments in, the underlying equity issuer or providing advisory services to the underlying equity issuer, such as merger and acquisition advisory services. In the course of our business, we or our affiliates may acquire non-public information about the underlying equity issuer. Neither we nor any of our affiliates undertakes to disclose any such information to you.

■ The amount you receive at maturity may be reduced because the antidilution adjustments the calculation agent is required to make do not cover every corporate event that could affect the underlying equity. The amount you receive at maturity will be subject to adjustment for a number of events arising from share splits and combinations, share dividends or other distributions, a number of other actions of the underlying equity issuer that modify its capital structure and a number of other transactions involving the underlying equity issuer, as well as for the liquidation, dissolution or winding up of the underlying equity issuer. You should refer to the section "Description of the ELKS — Dilution Adjustments" in the accompanying ELKS product supplement. The amount you receive at maturity will not be adjusted for other events that may adversely affect the price of the underlying equity, such as offerings of common stock for cash or in connection with acquisitions. Because of the relationship of the amount you receive at maturity to the closing price of the underlying equity, these other events may reduce the amount you receive at maturity on the ELKS. Additionally, the market price of the ELKS may be materially and adversely affected.

■ Market price influenced by inclusion of underwriting fees and projected profit from hedging activity. The inclusion of underwriting fees and projected profit from hedging in the issue price is likely to adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the price, if any, at which Citigroup Global Markets is willing to purchase the ELKS in secondary market transactions will likely be lower than the issue price, since the issue price includes and secondary market prices are likely to exclude, underwriting fees paid with respect to the ELKS, as well as the cost of hedging our obligations under the ELKS. The cost of hedging includes the projected profit that our affiliates may realize in consideration for assuming the risks inherent in managing the hedging transactions. The secondary market prices for the ELKS are also likely to be reduced by the costs of unwinding the related hedging transaction. Our affiliates may realize a profit from the expected hedging activity even if the market value of the ELKS declines. In addition, any secondary market prices for the ELKS may differ from values determined by pricing models used by Citigroup Global Markets, as a result of dealer discounts, mark-ups or other transaction costs. For further information on our use of proceeds and hedging, see “Can You Tell Me More About the Effect of Citigroup Funding’s Hedging Activity?” in the accompanying ELKS product supplement.

■ No shareholder rights. Investing in the ELKS is not equivalent to investing in the underlying equity. Investors in the ELKS will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the underlying equity.

■ The U.S. federal income tax consequences of an investment in the ELKS are uncertain. There is no direct legal authority as to the proper treatment of the ELKS for U.S. federal income tax purposes, and the issuer’s counsel has not rendered an opinion as to their proper tax treatment.

● Please read the discussion under "Fact Sheet — General Information —Tax considerations" in this offering summary and the discussion under “Certain United States Federal Income Tax Considerations” in the accompanying ELKS product supplement (together the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the ELKS. If the IRS were successful in asserting an alternative treatment for the ELKS, the timing and character of income on the ELKS might differ significantly from the tax treatment described in the Tax Disclosure Sections. The issuer does not plan to request a ruling from the IRS regarding the tax treatment of the ELKS, and the IRS or a court may not agree with the tax treatment described in this offering summary and the accompanying ELKS product supplement. On December 7, 2007, the Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. While it is not entirely clear whether the ELKS would be viewed as similar to the prepaid forward contracts described in the notice, it is possible that any Treasury regulations or other guidance issued after consideration of these issues could materially and adversely affect the tax consequences of an investment in the ELKS, possibly with retroactive effect. The notice focuses on a number of issues, the most relevant of which for holders of the ELKS are the character and timing of income or loss (including whether the option premium should be required to be included currently as ordinary income) and the degree, if any, to which income realized by non-U.S. investors should be subject to withholding tax. Non-U.S. Holders should note that we currently do not intend to withhold on any payments made with respect to the ELKS to Non-U.S. Holders (subject to compliance by such holders with certification requirements necessary to establish an exemption from withholding). However, in the event of a change of law or any formal or informal guidance by the IRS, Treasury or Congress, we may decide to withhold on payments made with respect to the ELKS to Non-U.S. Holders, and we will not be required to pay any additional amounts with respect to amounts withheld. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the ELKS, including possible alternative treatments, the issues presented by this notice, any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction, and the possible effects of changes in Federal or other tax laws including those discussed in the Tax Disclosure Sections.

Equity Linked Securities ("ELKS^®")

Other Risk Factors

str

■ There are important differences between the rights of holders of ADRs representing ordinary shares of Barclays PLC and the rights of holders of ordinary shares of Barclays PLC. Because the ELKS are linked to the performance of an ADR representing ordinary shares of Barclays PLC, you should be aware that your ELKS are linked to the price of the ADRs and not the ordinary shares of Barclays PLC (which we refer to as the underlying equity) and there exist important differences between the rights of holders of ADRs and the underlying equity. Each ADR is a security evidenced by American Depositary Shares that represents one ordinary share of Barclays PLC. The ADRs are issued under a deposit agreement, which sets forth the rights and responsibilities of the ADR depositary, Barclays PLC, and holders of the ADRs, which may be different from the rights of holders of the underlying equity. For example, Barclays PLC may make distributions in respect of the underlying equity that are not passed on to the holders of its ADRs. Any such differences between the rights of holders of the ADRs and holders of the underlying equity may be significant and may materially and adversely affect the value of the ELKS.

■ Exchange listing and secondary market. The ELKS will not be listed on any securities exchange. Although Citigroup Global Markets intends to make a market in the ELKS, it is not obligated to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the ELKS easily. Because we do not expect that other broker-dealers will participate significantly in the secondary market for the ELKS, the price at which you may be able to trade your ELKS is likely to depend on the price, if any, at which Citigroup Global Markets is willing to transact. If, at any time, Citigroup Global Markets were not to make a market in the ELKS, it is likely that there would be no secondary market for the ELKS. Accordingly, you should be willing to hold your ELKS to maturity.

■ The calculation agent, which is an affiliate of the issuer, will make determinations with respect to the ELKS. As calculation agent, Citigroup Global Markets will determine the initial equity price, whether the closing price of the underlying equity on any trading day from but excluding the pricing date to and including the valuation date decreases to or below the downside threshold closing price, whether a market disruption event has occurred, the appropriate payment you receive at maturity (including, if you elect to receive the cash value of the underlying equity at maturity, such cash value), and any adjustments to the equity ratio to reflect certain corporate and other events. Any of these determinations made by Citigroup Global Markets, in its capacity as calculation agent, including adjustments to the equity ratio, may adversely affect the payment to you on the ELKS at maturity.

■ Citigroup Funding’s hedging and trading activity could adversely affect the value of the ELKS. We expect to hedge our obligations under the ELKS through one or more of our affiliates, which will carry out hedging activity related to the ELKS, including trading in the underlying equity as well as in other instruments related to the underlying equity. Our affiliates also trade the underlying equity and other financial instruments related to the underlying equity on a regular basis as part of their general broker-dealer and other businesses. Any of this hedging or trading activity on or prior to the pricing date could potentially increase the price of the underlying equity and, accordingly, potentially increase the initial equity price used to calculate the downside threshold closing price and, therefore, potentially increase the downside threshold closing price relative to the price of the underlying equity absent such hedging or trading activity. Additionally, such hedging or trading activity could potentially affect whether the closing price of the underlying equity on any trading day from but excluding the pricing date to and including the valuation date decreases to or below the downside threshold closing price and, therefore, whether or not you will receive the stated principal amount of the ELKS or ADRs (or the cash value of those ADRs based on their closing price on the valuation date) at maturity. Furthermore, if the closing price of the underlying equity on any trading day has decreased to or below the downside threshold closing price such that you could receive ADRs of the underlying equity (or, at your option, the cash value of those ADRs based on their closing price on the valuation date) at maturity, our affiliates’ trading activity prior to or at maturity could adversely affect the closing price of those ADRs of the underlying equity.

■ Affiliate research reports and commentary. Citigroup Investment Research or other affiliates of Citigroup Funding may publish research reports or otherwise express opinions or provide recommendations from time to time regarding Barclays ADRs or other matters that may influence the price of Barclays ADRs and, therefore, the value of the ELKS. Any research, opinion or recommendation expressed by Citigroup Investment Research or other Citigroup Funding affiliates may not be consistent with purchasing, holding or selling the ELKS.

For further discussion of these and other risks you should read the section entitled "Risk Factors Relating to the ELKS" in the accompanying ELKS product supplement and “Risk Factors” in the related prospectus supplement for a full description of risks. The issuer also urges you to consult your investment, legal, tax, accounting and other advisers, before you invest in the ELKS.
