· You may lose a significant portion or all of your investment.

· You will not receive any contingent coupon payment for any quarterly observation period during which a coupon barrier event occurs.

· The quarterly contingent coupon payment is contingent on the closing level of each underlying index on each trading day throughout the observation periods.

· You will not benefit in any way from the performance of the better performing underlying indices.

· You will be subject to risks relating to the relationship among the underlying indices.

· Higher contingent coupon rates are associated with greater risk.

· You may not be adequately compensated for assuming the downside risk of the worst performing underlying index.

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

· The securities offer downside exposure to the worst performing underlying index, but no upside exposure to the underlying indices.

· Any early redemption payment or payment at maturity will depend on the closing levels of the underlying indices solely on the relevant dates, which makes the securities particularly sensitive to the volatility of the underlying indices.

· 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.
