Strategy Focus

Designed to realize the spread, if any, between the stock price of the target company after the public announcement of its proposed acquisition and the price offered by the acquirer to pay for the stocks of the target company.

Deal universe includes the United States, Canada and Western Europe.

Potential gains realized when deals are completed, and potential losses incurred when deals break.

Index Performance (December 31, 2009 - June 29, 2012)

The above graph sets forth the historical performance of the Index from December 31, 2009 through June 29, 2012. The index rules were revised on September 1, 2010 and therefore, the index performance and Index levels prior to such date do not reflect the modification of the index rules that took place on that date. Historical performance is not indicative of future performance. Credit Suisse Merger Arbitrage Liquid Index (Net) includes 0.50% p.a. of index calculation fees. The above graph includes this index calculation fee but does not reflect the accrued fee amount and the leverage charge associated with the ETNs, which will reduce the amount of the return on the ETNs at maturity or upon repurchase by Credit Suisse. The historical index performance does not reflect how a monthly compounding leveraged investment (such as the ETNs) would have performed over the same period of time.

Index Overview

The Index attempts to reflect the returns that would be generated by a merger arbitrage investment strategy in accordance with the Index rules to reflect publicly announced merger and acquisition transactions meeting certain conditions.

The Index is calculated intraday and benefits from transparent rules-based construction.

Leverage Methodology

Provides leveraged exposure to changes in the monthly closing level of the Index (minus costs and fees), increasing exposure in response to that month’s gains or reducing exposure in response to that month’s losses.

Leverage starts at two times exposure at the beginning of each month. Because the leveraged portion is held constant throughout the month, the actual leverage decreases with net gains in the Index and increases with net losses in the Index.

Because of the monthly rebalancing, the nature of compounding, fees, and leverage charges, the performance of the ETNs over months or years can differ significantly from the performance of the Index during the same period of time.

The Index Methodology*


Liquidity Constraints	Narrow deal universe to include only North American and Western European merger and acquisition deals with the following liquidity features: n Target has market cap of > $500 M n Target has sufficient trading volume n Acquirer’s stock, in both stock and cash and stock deals, is easy to borrow
Arbitrage Constraints	Apply systematic constraints intended to ensure deals have arbitrage potential: n Positive acquisition premium n Offer is for substantially all shares outstanding of target n Acquirer does not already own substantially all of the target’s shares
Weight and Rebalancing	Incorporate rebalancing procedure and risk constraints: n Rebalancing occurs when an index component is added to the Index n Deals are asset weighted capped n Leverage and short exposure are constrained n Turnover is controlled through rebalancing procedures

The above index methodology is a general summary of the rules governing the Index and exceptions to this summary may apply under certain defined circumstances. Please see the full description of the Index in the applicable pricing supplement.

Selected Investment Considerations

–

We have listed the ETNs on NYSE Arca under the symbol “CSMB”. 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.

–

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 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.

–

The performance of the Index may not be entirely representative of the performance of the merger arbitrage strategy and there is no assurance that the strategy on which the Index is based will be successful.

–

The ETNs are designed to reflect a leveraged exposure to the performance of the Index on a monthly basis, but their returns over longer periods of time can, and most likely will differ significantly from two times the return on a direct investment in the Index. The ETNs are very sensititve to changes in the performance of the Index, and returns on the ETNs may be negatively impacted in complex ways by volatility of the Index on a monthly basis. Accordingly, the ETNs should be purchased only by knowledgeable investors who understand the potential consequences of investing in the Index and of seeking monthly compounded leveraged investment results. Investors should actively and frequently monitor their investments in the ETNs.

–

The ETNs do not have a minimum payment at maturity or daily repurchase value and are fully exposed on a leveraged basis 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, taking into account the leveraged factor, to offset the applicable fees and charges.

–

We have the right to repurchase your ETNs in whole but not in part on any business day during the term of the ETNs. 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.

–

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.

–

An investment in the ETNs involves significant risks. The selected investment considerations herein are not intended as a complete description of all risks associated with the ETNs.
