Hypothetical Payout Profile (Maturity Payment Amount)

If the securities are not automatically called prior to stated maturity and the ending level of the lowest performing Index on the final calculation day is less than its threshold level, you will lose more than 25%, 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 any Index, but you will have full downside exposure to the lowest performing Index on the final calculation day if the ending level of that Index is less than the downside threshold level.

We estimate that the value of each security on the pricing date will be approximately $969.40, or within $30.00 of that estimate. See “Estimated Value of the Securities” in the accompanying preliminary pricing supplement for more information.
