Overview of the Notes
 
The Principal Protected Notes Based Upon the Brazilian Real (the “Notes”) are offered by Citigroup Funding Inc. and have a maturity of approximately 2.25 to 2.50 years (to be determined on the Pricing Date). The Notes are 100% principal protected if held to maturity, subject to the credit risk of Citigroup Inc. The Notes combine the investment characteristics of debt and currency investments and pay an amount at maturity that will depend on the percentage change in the value of the Brazilian real relative to the U.S. dollar, as measured by the BRL/USD Exchange Rate. If the Ending Exchange Rate is less than or equal to the Starting Exchange Rate, the payment you receive at maturity for each Note will equal $10. If the Ending Exchange Rate is greater than the Starting Exchange Rate, the payment you receive at maturity will be greater than the amount of your initial investment in the Notes. In such case, the return on a Note will be approximately 100% (to be determined on the Pricing Date) of the return on an investment directly linked to the Brazilian real because of the Participation Rate of approximately 100% (to be determined on the Pricing Date).
 
Some key characteristics of the Notes include:
 
n   Principal Protection. Your initial investment is 100% principal protected, subject to the credit risk of Citigroup Inc., if you hold your Notes to maturity. Notes sold in the secondary market prior to maturity are not principal protected. If you hold your Notes to maturity, you will receive at maturity an amount in cash equal to your initial investment plus the Currency Return Amount, which may be positive or
zero, subject to the Participation Rate. If the Ending Exchange Rate is greater than the Starting Exchange Rate, the Currency Return Amount will be positive. In all other circumstances, the Currency Return Amount will be zero, and at maturity you will receive only your initial investment.
 
n   No Periodic Payments. The Notes will not pay any periodic interest or other periodic payments. Instead, the return on the Notes, if any, will be paid at maturity based upon the percentage change in value of the Brazilian real relative to the U.S. dollar, as measured by the BRL/USD Exchange Rate, during the term of the Notes. The return on the Notes will vary depending on the performance of the Brazilian real and may be lower than that of a conventional fixed-rate debt security. The return on the Notes may be zero .
 
n   Tax Treatment. The federal income tax treatment of the Notes differs from the tax treatment of traditional fixed-rate notes. The federal income tax treatment of the Notes will require U.S. investors to include original issue discount (“OID”) for U.S. federal income tax purposes in gross income on a constant yield basis annually over the term of the Notes, although U.S. investors will receive no payments with respect to the Notes before maturity. Non-U.S. investors will generally not be subject to U.S. income or withholding tax, provided that certain certification requirements are met.

are not guaranteed by the FDIC under the Temporary Liquidity Guarantee Program.

Types of Investors
 
The Notes are not a suitable investment for investors who require regular fixed-income payments since no interest payments or investment returns, if any, will be paid prior to the maturity of the Notes. These Notes may be an appropriate investment for the following types of investors:
 
n   Investors looking for exposure to currency-linked investments on a principal protected basis.
 
n   Investors who expect appreciation of the Brazilian real relative to the U.S. dollar over the term of the Notes.
 
n   Investors who seek to add a currency-linked investment to diversify their underlying asset class exposure.
