Trading day:	For any underlying index, a scheduled trading day for that underlying index on which a market disruption event has not occurred with respect to that underlying index.
Automatic early redemption:	If, on any potential redemption date, the closing level of the worst performing underlying index on that potential redemption date is greater than or equal to its initial index level, each security you then hold will be automatically redeemed on the related contingent coupon payment date for an amount in cash equal to the early redemption payment.  If the securities are redeemed, no further payments will be made.

· The securities may be automatically called prior to maturity, limiting your opportunity to receive contingent coupon payments.

· Immediately following issuance, any secondary market bid price provided by Citigroup Global Market Inc., and the value that will be indicated on any brokerage account statements prepared by Citigroup Global Market Inc. or its affiliates, will reflect a temporary upward adjustment.
