Risk Factors

Please see the Preliminary Offering Documents for a description of certain risks related to this investment, including, but not limited to, the following: 

· Depending on the performance of the Market Measure as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

· Payments on the notes, including repayment of principal, are subject to the credit risk of Credit Suisse. If Credit Suisse becomes insolvent or is unable to pay its obligations, you may lose up to 95.00% of your investment.

· Your investment return, if any, is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the Basket Components.

· Changes in the level of one of the Basket Components may be offset by changes in the levels of the other Basket Components.

· The initial estimated value of the notes on the pricing date will be less than their public offering price.

· If you attempt to sell the notes prior to maturity, their market value may be lower than both the public offering price and the initial estimated value of the notes on the pricing date.

· You will have no rights of a holder of the securities included in the Basket Components, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

· The notes are subject to risks associated with small-size capitalization companies.

· Your return on the notes may be affected by factors affecting the international securities markets, specifically changes in the countries represented by the SX5E. In addition, you will not obtain the benefit of any increase in the value of the euro against the U.S. dollar, which you would have received if you had owned the securities in the SX5E during the term of your notes, although the level of the SX5E may be adversely affected by general exchange rate movements in the market.

Final terms will be set on the pricing date within the given range for the specified Market-Linked Investment. Please see the Preliminary Offering Documents
