Selected Risk Considerations			Additional Information
• You may lose a significant portion 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 performer is less than its final buffer value, which means that the worst performer has depreciated from its initial underlying value by more than the buffer percentage, you will lose 1% of the stated principal amount of your securities for every 1% by which that depreciation exceeds the buffer percentage. • Your potential return on the securities from appreciation of the worst performer is limited. If the final underlying value of the worst performer is greater than or equal to its initial underlying value, your potential total return on the securities at maturity is limited to the maximum upside return, even if the worst performing underlying appreciates by significantly more than the maximum upside return. • Your potential for positive return from depreciation of the worst performer is limited. The return potential of the securities in the event that the final underlying value is less than its initial underlying value is limited by the final buffer value. • 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 Russell 2000^® Index 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.
