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 any Underlying is less than or equal to the Knock-In Level. 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, including coupon payments, are subject to the credit risk of Credit Suisse.

•

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

•

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 fluctuations in the level of the Underlyings to the same degree for each Underlying.
