Selected Risk Considerations

•You may not receive any return on your investment in the securities. You will receive a positive return on your investment in the securities only if the underlying appreciates from the initial underlying value to the final underlying value. If the final underlying value is less than or equal to the initial underlying value, you will receive only the stated principal amount for each security you hold at maturity.

•Although the securities provide for the repayment of the stated principal amount at maturity, you may nevertheless suffer a loss on your investment in real value terms if the underlying declines or does not appreciate from the initial underlying value to the final underlying value.

•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.

•Sale of the securities prior to maturity may result in a loss of principal.

•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.
