Selected Risk Considerations	Additional Information
•    You may lose a significant portion or all of your investment. Your payment at maturity will depend on the final underlying value. If the final underlying value is less than the final barrier value, you will lose 1% of the stated principal amount of your securities for every 1% by which the underlying has declined from the initial underlying value. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment. •    Your potential for positive return from depreciation of the underlying is limited. •    The securities do not pay interest. •    You will not receive dividends or have any other rights with respect to the underlying. •    Your payment at maturity depends on the closing value of the underlying on a single day. •    The securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc. If Citigroup Global Markets Holdings Inc. defaults on its obligations under the securities and Citigroup Inc. defaults on its guarantee obligations, you may not receive anything owed to you under the securities. •    The securities will not be listed on any securities exchange and you may not be able to sell them prior to maturity. •    The estimated value of the securities on the pricing date will be less than the issue price. For more information about the estimated value of the securities, see the accompanying preliminary pricing supplement. •    The value of the securities prior to maturity will fluctuate based on many unpredictable factors. •    The underlying is expected to underperform the total return performance of the S&P 500® Index because the performance of the underlying is expected to be reduced by an implicit financing cost, and any increase in this cost will adversely affect the performance of the securities. •    The issuer and its affiliates may have conflicts of interest with you. •    The U.S. federal tax consequences of an investment in the securities are unclear.
