Product Summary

• 3-Year Buffered Accelerated Return Equity Securities (BARES) linked to the performance of the Russell 2000^® Index.

• If the Final Level is less than the Initial Level by not more than the Buffer Amount, then the investor will be entitled to receive the principal amount at maturity.

• If the Final Level is less than the Initial Level by more than the Buffer Amount, then the principal amount the investor will be entitled to receive will decrease 1% for every 1% decline in the Underlying beyond the Buffer Amount.

• If the Final Level is equal to or greater than the Initial Level, then the investor will be entitled to the Fixed Payment Percentage.

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