If the final index level of the worst performing underlying index is less than its barrier level, the payment at maturity will be less, and possibly significantly less, than $600.00 per security.

Selected Risk Considerations
·You may lose some or all of your investment. If the final index level of the worst performing underlying index is less than its barrier level, you will lose 1% of the stated principal amount of the securities for every 1% by which the worst performing underlying index has declined from its initial index level. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment.
·The securities do not pay interest.
·Your potential return on the securities is limited. Your potential total return on the securities at maturity is limited to the maximum return at maturity of 60.00%, which is equivalent to a maximum return at maturity of $600.00 per security.
·The return on the securities depends solely on the performance of the worst performing underlying index, and you will not benefit in any way from the performance of the better performing underlying index.
·You will be subject to risks relating to the relationship between the underlying indices.
·Investing in the securities is not equivalent to investing in either underlying index. You will not have voting rights, rights to receive dividends or any other rights with respect to the stocks that constitute the underlying indices.
·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.
