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 automatically redeemed prior to maturity, your payment at maturity will depend on the final underlying value. If the final underlying value is less than the final barrier value, you will lose 1% of the stated principal amount of your securities for every 1% by which the underlying has declined from the initial underlying value. 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 is limited.

•The securities do not pay interest.

•You will not receive dividends or have any other rights with respect to the underlying.

•The securities may be automatically redeemed prior to maturity.

•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 Index is highly risky because it may reflect highly leveraged exposure to the Underlying Futures Index and may therefore experience a decline that is many multiples of any decline in the Underlying Futures Index.

•The Index may realize significant losses if it is not consistently successful in increasing exposure to the Underlying Futures Index in advance of increases in the Underlying Futures Index and reducing exposure to the Underlying Futures Index in advance of declines in the Underlying Futures Index.

•The Index may be adversely affected by a time lag in its volatility targeting mechanism.

•The Index may be adversely affected by a “decay” effect.

•The Underlying Futures Index is expected to underperform the S&P 500^® Index because of an implicit financing cost.

•The performance of the Index will be reduced by a decrement of 6% per annum.

•The Index may not fully participate in any appreciation of the Underlying Futures Index.

•The Index may perform less favorably than it would if its volatility targeting mechanism were based on an alternative volatility measure, such as actual realized volatility, rather than implied volatility.

•The Index may significantly underperform the S&P 500^® Index.

•The Index has limited actual performance information.

•An affiliate of ours participated in the development of the Index.
