Selected Risk Considerations

You may lose a significant portion or all of your investment. Unlike conventional debt securities, the securities do not provide for the repayment of the stated principal amount at maturity in all circumstances. If the securities are not redeemed prior to maturity and the final underlying value is less than the final barrier value, you will not receive the stated principal amount of your securities at maturity and, instead, will receive underlying shares of the underlying (or, in our sole discretion, cash based on the value thereof) that will be worth significantly less than the stated principal amount and possibly nothing. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment.

You will not receive any contingent coupon following any valuation date on which the closing value of the underlying on that valuation date is less than the coupon barrier value.

We may redeem the securities at our option, which will limit your ability to receive the contingent coupon payments.

The securities offer downside exposure, but no upside exposure, to the underlying.

The securities are particularly sensitive to the volatility of the closing value of the underlying on or near the valuation dates.

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 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.

The above summary of selected risks does not describe all of the risks associated with an investment in the securities. You should read the accompanying preliminary pricing supplement and product supplement for a more complete description of risks relating to the securities.
