Product Terms

If a Trigger Event occurs on any Trigger Observation Date, the securities will be automatically redeemed and investors will receive a cash payment for each $1,000 principal amount of securities equal to $1,000 plus the Automatic Redemption Premium applicable to that Trigger Observation Date.

If the securities are not automatically redeemed and the Final Level is greater than the Initial Level, you will participate in the appreciation, if any, of the Underlying.

If the securities are not automatically redeemed and the Final Level is equal to or less than the Initial Level, investors will receive the principal amount of the securities you hold at maturity.

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

The Underlying is designed to provide exposure to a hypothetical “balanced” portfolio while targeting a realized daily volatility of 5%. By “balanced” we mean the Underlying’s hypothetical portfolio may, under certain circumstances include both equity exposure, in the form of large-cap U.S. equities included in the Credit Suisse RavenPack AIS Index described in the accompanying underlying performance supplement and the accompanying underlying supplement; and fixed income exposure, in the form of U.S. Treasury note futures contracts tracked by the Fixed Income Indices described in the accompanying underlying performance supplement and the accompanying underlying supplement. “Balanced” does not imply any risk adjusted diversified asset class allocation or actual balance among asset classes. The Index Calculation Agent and Index Sponsor for the Underlying is an affiliate of ours. For more information on the Underlying, please see the underlying performance supplement and underlying supplement.
