Capped Return Enhanced Notes Based on the Common Stock of General Motors Company Due March     , 2016
 
Overview. The securities are unsecured senior debt securities issued by Citigroup Inc. Unlike conventional debt securities, the securities do not pay interest and do not repay a fixed amount of principal at maturity. Instead, the securities offer a payment at maturity that may be greater than, equal to or less than the stated principal amount, depending on the performance of the shares of common stock of General Motors Company (the “underlying shares”) from the initial share price to the final share price.
 
The securities offer leveraged exposure to a limited range of potential appreciation of the underlying shares as described below. In exchange for this leveraged exposure, investors in the securities must be willing to forgo (i) any appreciation of the underlying shares in excess of the maximum return at maturity specified below and (ii) any dividends that may be paid on the underlying shares. In addition, investors in the securities must be willing to accept full downside exposure to any depreciation of the underlying shares.
 
 
All payments on the securities are subject to the credit risk of Citigroup Inc. The securities will not be listed on any securities exchange and may have limited or no liquidity.

Selected Risk Considerations
 
·
You may lose some or all of your investment. If the final share price is less than the initial share price, you will lose 1% of the stated principal amount of the securities for every 1% by which the final share price is less than the initial share price. There is no minimum payment at maturity on the securities, and you may lose up to all of your investment.
 
·
Your potential return on the securities is limited to the maximum return at maturity. If the underlying shares appreciate by more than the maximum return at maturity, the securities will underperform a direct investment in the underlying shares.
 
·
The securities do not pay interest.
 
·
You will not have voting rights, rights to receive dividends or any other rights with respect to the underlying shares.
·
The securities are subject to the credit risk of Citigroup Inc. If Citigroup Inc. defaults on its obligations under the securities, you may not receive anything owed to you under the securities.
 
·
The securities will not be listed on a securities exchange and you may not be able to sell them prior to maturity.
 
·
The estimated value of the securities on the pricing date will be less than the issue price. For more information about the estimated value of the securities, see the accompanying preliminary pricing supplement.
 
·
The value of the securities prior to maturity is likely to be less than the issue price and will fluctuate based on many unpredictable factors.
 
·
Citigroup Inc. and its affiliates, and the placement agents and their affiliates, may have conflicts of interest with you.
 
·
The U.S. federal tax consequences of an investment in the securities are unclear.
