Investment Description

· Linked to the S&P 500^® Index (the “underlying”)

· Unlike ordinary debt securities, the notes do not pay interest. Instead, the notes offer the potential for a positive return at maturity based on the performance of the underlying from the initial underlying value to the final average underlying value, subject to a minimum return at maturity of at least 2% (to be determined on the pricing date) of the stated principal amount. The payment at maturity will reflect the following terms:

o If the final average underlying value is greater than the initial underlying value, you will receive the stated principal amount plus the greater of (i) the minimum return of at least 2% (to be determined on the pricing date) of the stated principal amount and (ii) a positive return equal to 100% of the percentage increase from the initial underlying value to the final average underlying value

o If the final average underlying value is less than or equal to the initial underlying value, you will receive the stated principal amount plus the minimum return of at least 2% (to be determined on the pricing date) of the stated principal amount

· The final average underlying value is based on the average of closing values of the underlying on specified dates occurring quarterly during the term of the notes

· All payments on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.; if Citigroup Global Markets Holdings Inc. and Citigroup Inc. default on their obligations, you could lose some or all of your investment

· No periodic interest payments or dividends

· The notes will not be listed on any securities exchange and, accordingly, may have limited or no liquidity. You should not invest in the notes unless you are willing to hold them to maturity.

* Expected. To the extent that the issuer makes any change to the expected pricing date or expected issue date, the valuation dates and maturity date may also be changed in the issuer’s discretion to ensure that the term of the notes remains the same.

On the date of the related pricing supplement, Citigroup Global Markets Holdings Inc. expects that the estimated value of the notes on the pricing date will be at least $900.00 per note, which will be less than the public offering price. The estimated value of the notes is based on CGMI’s proprietary pricing models and Citigroup Global Markets Holdings Inc.’s internal funding rate. It is not an indication of actual profit to CGMI or other of Citigroup Global Markets Holdings Inc.’s affiliates, nor is it an indication of the price, if any, at which CGMI or any other person may be willing to buy the notes from you at any time after issuance. See “Valuation of the Notes” in the accompanying pricing supplement.

The notes have complex features and investing in the notes involves risks not associated with an investment in conventional debt securities. See “Risk Factors” beginning on page 3 in this term sheet, “Summary Risk Factors” in the accompanying pricing supplement and “Risk Factors Relating to the Notes” in the accompanying product supplement.

This introductory term sheet does not provide all of the information that an investor should consider prior to making an investment decision.

Investors should carefully review the accompanying pricing supplement, product supplement, underlying supplement, prospectus supplement and prospectus before making a decision to invest in the notes.

NOT A BANK DEPOSIT AND NOT INSURED OR GUARANTEED BY THE FDIC OR ANY OTHER GOVERNMENTAL AGENCY

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 participation rate will be set at the lowest value indicated under “Key Terms” above. The actual minimum return will be determined on the pricing date.
