Hypothetical Returns

The table below is based on a range of hypothetical percentage changes from the initial underlying value to the hypothetical final average underlying value and illustrates:

• the hypothetical percentage change from the initial underlying value to the hypothetical final average underlying value;

• the hypothetical payment at maturity per note; and

• the hypothetical total pre-tax rate of return.

The table below is based on a hypothetical initial underlying value of 100 and does not reflect the actual initial underlying value. The table below assumes that the maximum return will be set at the lowest value indicated uner “Key Terms” above. The actual maximum return will be determined on the pricing date.

Risk Factors

An investment in the notes is significantly riskier than an investment in conventional debt securities. The notes are subject to all of the risks associated with an investment in our conventional debt securities (guaranteed by Citigroup Inc.), including the risk that we and Citigroup Inc. may default on our obligations under the notes, and are also subject to risks associated with the underlying. Accordingly, the notes are suitable only for investors who are capable of understanding the complexities and risks of the notes. You should consult your own financial, tax and legal advisors as to the risks of an investment in the notes and the suitability of the notes in light of your particular circumstances.

You should read this summary together with the full description of the risk considerations provided for in the Preliminary Pricing Supplement and the more detailed description of risks relating to an investment in the notes contained in the section “Risk Factors Relating to the Notes” beginning on page EA-6 in the accompanying product supplement.
