Linked to the Performance of the Lowest Performing of the S&P 500^® Index and the Russell 2000^® Index

Product Terms

If the Final Level of the Lowest Performing Underlying is equal to or greater than its Initial Level, then you will benefit from the greater of the Fixed Payment Percentage and the uncapped participation in the appreciation, if any, of the Lowest Performing Underlying.

If the Final Level of the Lowest Performing Underlying is less than its Initial Level and a Knock-In Event has not occurred, you will receive the principal amount of the securities you hold at maturity.

If the Final Level of the Lowest Performing Underlying is less than its Initial Level and a Knock-In Event has occurred, you will be fully exposed to any depreciation in the Lowest Performing Underlying. You could lose your entire investment.

Any payment on the securities is subject to our ability to pay our obligations as they become due.
