Certain Product Risks

Your investment may result in a loss of up to 100% of the principal amount. The Redemption Amount will be less than the principal amount if the Final Level of the Lowest Performing Underlying is less than its Initial Level and a Knock-In Event occurs. In such case, you will be fully exposed to any depreciation in the Lowest Performing Underlying.

The value of the securities and the payment of any amount due on the securities are subject to the credit risk of Credit Suisse.

The Redemption Amount will be based on the Underlying Return of the Lowest Performing Underlying and, therefore, you will not benefit from the performance of any other Underlying

The securities are exposed to the risk of fluctuations in the level of the Underlyings to the same degree for each Underlying.

The securities do not pay interest.

The return on the securities is affected by the Final Level of the Lowest Performing Underlying and the occurrence of a Knock-In Event.
