·    You may not receive any return on your investment in the notes. You will receive a positive return on your investment in the notes only if the basket appreciates from the initial basket level to the final basket level. If the final basket level is equal to or less than the initial basket level, you will receive only the stated principal amount of $1,000 for each note you hold at maturity.

·    The notes do not pay interest.

·    The notes are designed for investors who seek exposure to the basket components but who are willing to forgo any dividends or distributions on the basket components in exchange for the repayment of principal at maturity if the basket depreciates. Dividend or distribution yields on the basket components would be expected to represent a significant portion of the overall return on a direct investment in the basket components, but will not be reflected in the performance of the basket components as measured for purposes of the notes (except to the extent that dividends and distributions reduce the levels or prices of the basket components). The magnitude of this lost dividend or distribution yield may be particularly significant in the case of the iShares^® iBoxx^® $ High Yield Corporate Bond ETF. As a result, your return on the notes may be significantly less than the return that could be achieved on a direct investment in the basket components.

·    Your payment at maturity depends on the closing levels or closing prices, as applicable, of the basket components on a single day.

·    Investing in the notes is not equivalent to investing in the basket components. You will not have voting rights, rights to receive any dividends on stocks or distributions of interest on bonds or any other rights with respect to the basket components or the securities included in or held by the basket components.

·    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.

·    Sale of the notes prior to maturity may result in a loss of principal.

·    The notes 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 notes on the pricing date will be 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 basket components may offset each other.

·    The basket components may be highly correlated in decline.

·    The EURO STOXX 50^® Index is subject to risks associated with non-U.S. markets.

·    The performance of the EURO STOXX 50^® Index will not be adjusted for changes in the currency exchange rate between the euro and the U.S. dollar.

·    The iShares^® iBoxx^® $ High Yield Corporate Bond ETF is subject to significant risks, including interest rate-related and credit-related risks.

·    The issuer and its affiliates may have conflicts of interest with you.

·    The U.S. federal tax consequences of an investment in the notes are unclear.
