Citigroup Global Markets Holdings Inc. Guaranteed by Citigroup Inc. Selected Risk Considerations • You may not receive any return on your investment in the notes . • The notes do not pay interest. • The term of the notes may be as short as one year. • Your potential return on the notes in connection with an early redemption is limited. • We may redeem the notes prior to maturity. • Although the notes provide for the repayment of the stated principal amount at maturity, you may nevertheless suffer a loss on your investment in real value terms if the notes are not redeemed prior to maturity or if the worst performing underlying on the valuation date declines or does not appreciate sufficiently from its initial underlying value to its final underlying value . • You will not benefit in any way from the performance of any better performing underlying. • Your payment at maturity will depend on the closing values of the underlyings solely on the valuation date, which makes the notes particularly sensitive to volatility in the closing values of the underlyings on or near the valuation date. • The notes are subject to heightened risk because they have multiple underlyings . • You will be subject to risks relating to the relationship among 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 notes. All that is necessary for the notes to perform poorly is for one of the underlyings to perform poorly. • The return on the notes depends solely on the performance of the worst performer. As a result, t he notes are subject to the risks of each of the underlyings and will be negatively affected if any one performs poorly. • You will not receive dividends or have any other rights with respect to the underlyings . • The notes 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 notes and Citigroup Inc. defaults on its guarantee obligations, you may not receive anything owed to you under the notes. • The notes will not be listed on any securities exchange and you may not be able to sell them prior to maturity. • Sale of the notes prior to maturity may result in a loss of principal. • The estimated value of the notes on the pricing date is less than the issue price. For more information about the estimated value of the notes, see the accompanying preliminary pricing supplement. • The value of the notes 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 above summary of selected risks does not describe all of the risks associated with an investment in the notes.
