For each $1,000 stated principal amount note you hold at maturity, you will receive an amount in cash determined as follows:

▪   If the final index level is greater than the initial index level:
$1,000 + ($1,000 × the index return × the upside participation rate)

▪   If the final index level is less than or equal to the initial index level:
$1,000 + ($1,000 × the index return), subject to the minimum payment at maturity

If the final index level depreciates from the initial index level, you will be exposed to the first 5% of that depreciation and your payment at maturity will be less than the stated principal amount per note. You should not invest in the notes unless you are willing and able to bear the risk of losing up to $50 per note. The notes are unsecured debt securities. All payments on the notes are subject to the credit risk of Citigroup Global Markets Holdings Inc. and Citigroup Inc.
