Index Composition (December 2009 - September 2013)


Selected Investment Considerations

– The ETNs do not have a minimum payment at maturity or daily repurchase value and are fully exposed to any decline in the Index. Furthermore, the return at maturity or upon repurchase will be reduced by the fees and charges associated with the ETNs and the Index. Therefore, the level of the Index must increase by an amount sufficient, to offset the applicable fees and charges.
– You will not receive any periodic interest payments on the ETNs.
– We have listed the ETNs on NYSE Arca under the symbol “CSLS”. We expect that investors will purchase and sell the ETNs primarily in the secondary market. We have no obligation to maintain this listing on NYSE Arca or any listing on any other exchange, and may delist the ETNs at any time.
– The indicative value of the ETNs is not the same as the closing price or any other trading price of the ETNs in the secondary market. The trading price of the ETNs at any time is the price at which you may be able to sell your ETNs in the secondary market at such time, if one exists. The trading price of the ETNs at any time may vary significantly from the indicative value of such ETNs at such time. Before trading in the secondary market, you should compare the indicative value with the then-prevailing trading price of the ETNs.
– Although the return on the ETNs will be based on the performance of the Index, the payment of any amount due on the ETNs, including any payment

upon repurchase or at maturity, is subject to the credit risk of Credit Suisse. Investors are dependent on Credit Suisse’s ability to pay all amounts due on the ETNs, and therefore investors are subject to our credit risk. In addition, any decline in our credit ratings, any adverse changes in the market’s view of our creditworthiness or any increase in our credit spreads is likely to adversely affect the market value of the ETNs prior to maturity.

– While the Index aims to replicate the performance of the Target Index by tracking the performance of non-hedge fund, transparent market measures, the Target Index tracks a variety of investments many of which are not transparent.
– The performance of the Index may not correlate with the performance of the Target Index and there is no assurance that the strategy on which the Index is based will be successful.
– Tax consequences of the ETNs are uncertain and potential investors should consult their tax advisors regarding the U.S. federal income tax consequences of an investment in the ETNs.
– We have the right to repurchase your ETNs in whole but not in part, if the principal amount of the ETNs outstanding is $10,000,000 or less. The amount you may receive upon a repurchase by Credit Suisse may be less than the amount you would receive on your investment at maturity or if you had elected to have us repurchase your ETNs at a time of your choosing.
