Buffered Accelerated Return Equity Securities (BARES)

BARES offer a return linked to the performance of the underlying(s) with leverage on the upside, subject to a return cap, if applicable, and a buffer on the downside.

Overview   Buffered Accelerated Return Equity Securities (the “securities”) provide a return linked to the performance of the individual underlying(s) (the individual underlying, a basket or, in the case of multiple underlyings, the lowest performing of the underlyings, the “underlying”). The securities offer a leveraged participation in the appreciation, if any, of the underlying from its initial level to its final level. In some cases, the securities are subject to an underlying return cap on this leveraged upside participation. Alternatively, the securities may instead offer a fixed payment percentage if the underlying appreciates. Additionally, the securities provide a buffer if the underlying has depreciated at maturity. If the final level of the underlying has depreciated from its initial level but by not more than the buffer amount, the investor will be entitled to receive an amount equal to the principal amount. If the final level of the underlying has depreciated by more than the buffer amount from its initial level, the investor will be exposed on a one-for-one basis to the depreciation of the underlying beyond the buffer amount and will receive less than 100% of the principal amount. Alternatively, the securities may also include a downside participation rate. If the final level of the underlying has depreciated by more than the buffer amount from its initial level, the investor will be exposed on a leveraged basis to the decline in the underlying and will receive less than 100% of the principal amount. Any payment on the securities is subject to the ability of Credit Suisse AG (“Credit Suisse” or the “Issuer”) to pay its obligations as they become due. The securities will not be listed on any exchange.   Investing in the securities involves a number of risks. See “Summary of Selected Product Risks” herein, “Selected Risk Considerations” in the applicable pricing supplement and “Risk Factors” beginning on page PS-3 of the accompanying product supplement.   Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the securities or determined if this product summary supplement is truthful or complete. Any representation to the contrary is a criminal offense.

Sample Return Profile at Maturity

These sample terms are presented to illustrate how a BARES deal might work. These sample terms are hypothetical and the actual terms will vary depending on the relevant terms of the specific securities.

If the final level of the underlying is equal to or greater than its initial level, the investor will be entitled to receive the principal amount of the securities multiplied by (1 + the lesser of (i) the underlying return cap and (ii) percentage change in the underlying from the initial level to the final level multiplied by the upside participation rate).

If the final level of the underlying is less than its initial level by not more than the buffer amount, the investor will be entitled to receive the principal amount of the securities.

If the final level of the underlying is less than its initial level by more than the buffer amount, the investor will be entitled to receive the principal amount of the securities multiplied by (1 + [percentage change in the underlying from the initial level to the final level + buffer amount]).

Potential Upside

n The securities entitle an investor to receive a return at maturity that is based on the leveraged participation in the appreciation, if any, of the underlying to which it is linked, subject in some cases to an underlying return cap. It also features a buffer against the depreciation, if any, of the underlying at maturity.

n In lieu of an upside participation rate, some securities offer a fixed payment percentage if the underlying appreciates, irrespective of the extent of such appreciation.

Potential Downside

n If the underlying depreciates by more than the buffer amount at maturity, the investor will be fully exposed to the depreciation of the underlying beyond the buffer amount. Alternatively, if the securities have a downside participation rate, you may be fully exposed to such negative performance on a leveraged basis. You could lose your entire investment.

n If the securities are subject to an underlying return cap or provide for a fixed payment percentage, the payment on the securities will be capped at a certain level regardless of the appreciation in the underlying, which may be significant.

n The securities do not pay interest.

Summary of Selected Product Risks

n Your investment in the securities may result in a loss. If the final level is less than the initial level by more than the buffer amount, you may lose 1% of your principal for each 1% decline in the final level as compared to the initial level beyond the buffer amount. Alternatively, if the securities have a downside participation rate, you may be fully exposed to such negative performance on a leveraged basis. You could lose your entire investment.

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

n The securities do not pay interest.

n The securities may be fully exposed to the risk of fluctuations in the level of the underlying. In the case of multiple underlyings, the amount payable at maturity may be based on the depreciation or appreciation of the lowest performing underlying alone.

n The securities may be part of a basket and changes in the values of the basket components may offset each other. In calculating the basket return, increases in the level of one of the basket components may be moderated, or more than offset, by lesser increases or declines in the level of the other basket component(s).

n The securities will not pay more than the underlying return cap or fixed payment percentage, as applicable, regardless of the appreciation of the underlying.

n Credit Suisse currently anticipates that the value of the securities on the trade date will be less than the price the investor pays for the securities, reflecting the deduction of underwriting discounts and commissions and other costs of creating and marketing the securities. Prior to maturity, costs such as concessions and hedging may affect the value of the securities.

n The securities will not be listed on any securities exchange. Credit Suisse (or its affiliates) intends to offer to purchase the securities in the secondary market but it is not required to do so. The price at which the investor may be able to trade the securities is likely to depend on the price, if any, at which Credit Suisse (or its affiliates) is willing to buy the securities.

n The value of the securities will be affected by a number of economic, financial, political, regulatory and judicial factors that may either offset or magnify each other and the price at which the securities may be purchased or sold in the secondary market. For example, the creditworthiness of the Issuer, including actual or anticipated downgrades in the Issuer’s credit ratings, may be a contributing factor.

n Holders of the securities will not have voting rights or rights to receive cash dividends or other distributions with respect to the equity securities comprising the underlyings, if any.

n Credit Suisse and its affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent, hedging our obligations under the securities and determining the estimated value of the securities, and may have economic interests adverse to the investor.

n The U.S. federal income tax consequences of an investment in the notes are uncertain, and may be adverse to a holder of the securities. Investors in the securities should consult their tax advisor as to the specific tax consequences to them of owning and disposing of the securities, including the application of federal, state, local and foreign income and other tax laws based on their particular facts and circumstances.
