Hypothetical Payout Profile

If the ending level is less than the starting level, you will have 1-to-1 downside exposure to the first 10% decrease in the level of the Basket from the starting level to the ending level and you may lose up to 10% of the face amount.

Unlike ordinary debt securities, the securities do not pay interest or repay a fixed amount of principal at maturity. Instead, the securities provide for a maturity payment amount that may be greater than, equal to or less than the face amount of the securities, depending on the performance of the Index from its starting level to its ending level.

If the securities priced today, the estimated value of the securities would be between $925.48 (92.548%) and $955.48 (95.548%) per $1,000 face amount. See “The Bank’s Estimated Value of the Securities” in the preliminary pricing supplement.
