For each $1,000 stated principal amount security you hold at maturity: 

·     If the final underlying value is greater than or equal to the initial underlying value:
$1,000 + the digital return amount 

·     If the final underlying value is less than the initial underlying value:
a fixed number of underlying shares of the underlying equal to the equity ratio (or, if we elect, the cash value of those underlying shares based on the final underlying value) 

If the final underlying value is less than the initial underlying value, you will receive underlying shares (or, in our sole discretion, cash) expected to be worth less than the stated principal amount of your securities, and possibly nothing, at maturity. You should not invest in the securities unless you are willing and able to bear the risk of losing some, and possibly all, of your investment. The securities are unsecured debt securities. All payments on the securities are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.
