Hypothetical Payout Profile (maturity payment amount)

If the securities are not automatically called prior to stated maturity and the ending price is less than the threshold price, you will lose more than 35%, and possibly all, of the face amount of your securities at stated maturity.

Any return on the securities will be limited to the sum of your contingent coupon payments, if any. You will not participate in any appreciation of the Underlying Stock, but you will have full downside exposure to the Underlying Stock if the ending price is less than the threshold price.

On the date of the accompanying preliminary pricing supplement, the estimate initial value of the securities is $978.70 per security. The estimated initial value of the securities on the pricing date may differ from this value but will not be less than $938.70 per security. However, as discussed in more detail in the accompanying preliminary pricing supplement, the actual value of the securities at any time will reflect many factors and cannot be predicted with accuracy. See “Estimated Value of the Securities” in the accompanying preliminary pricing supplement.
