Citigroup Global Markets Holdings Inc. Guaranteed by Citigroup Inc. Selected Risk Considerations • You may lose a significant portion or all of your investment. Your payment at maturity will depend on the final underlying value of the worst performer. If the final underlying value of the worst performing underlying is less than its final barrier value, you will not be repaid the stated principal amount of your securities at maturity but, instead, will receive underlying shares of the worst performing underlying (or, in our sole discretion, cash based on its final underlying value) that will be worth less than your initial investment in the securities and may be worth nothing. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment. • Your potential return on the securities at maturity is limited to the digital return, even if the worst performer appreciates by significantly more than the digital return. • The securities do not pay interest. • The securities are subject to heightened risk because they have multiple underlyings. • The return on the securities depends solely on the performance of the worst performer. As a result, the securities are subject to the risks of each of the underlyings and will be negatively affected if any one underlying performs poorly. • You will be subject to risks relating to the relationship between the underlyings. The less correlated the underlyings, the more likely it is that any one of the underlyings will perform poorly over the term of the securities. All that is necessary for the securities to perform poorly is for one of the underlyings to perform poorly. • You will not receive dividends or have any other rights with respect to the underlyings. • Your payment at maturity depends on the closing value of the worst performer 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 iShares® Russell 2000 ETF is subject to risks associated with small capitalization stocks . • 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.
