PRODUCT SUPPLEMENT NO. I–D TO PROSPECTUS SUPPLEMENT
DATED JUNE 18, 2020 TO PROSPECTUS DATED JUNE 18, 2020

Securities Linked to the Performance of One or More Commodity Indices or a Basket of Commodity Indices

This product supplement sets forth terms that will apply generally to the securities offered by this product supplement, which we refer to as the “securities.” The specific terms of a particular issuance of securities, including the calculation of any amount due on the securities, will be set forth in a pricing supplement that we will deliver in connection with that issuance. You should read this product supplement together with such pricing supplement, any accompanying underlying supplements or other product supplements, as applicable, the prospectus supplement and the prospectus, which we refer to collectively as the “offering documents.” If the terms described in the applicable pricing supplement are inconsistent with those described herein or in the accompanying prospectus supplement or prospectus, the terms described in the applicable pricing supplement will control.

The securities are senior unsecured medium-term notes issued by Credit Suisse AG, acting through one of its branches, the return on which is linked to the positive or inverse performance of one or more commodity indices or a basket of commodity indices, as specified in the applicable pricing supplement. We refer generally to each commodity index as an “underlying” and to each underlying included in a basket as a “basket component.” The one or more underlyings or the basket to which the securities will be linked will be specified in the applicable pricing supplement. If the securities are linked to the performance of any other reference asset, the terms applicable to such reference asset will be set forth in the applicable product supplement, pricing supplement or other supplement.

The securities may be subject to an automatic redemption and/or may be redeemable at our option, in each case in whole or in part, as set forth in the applicable pricing supplement, together with any applicable coupons. We refer to such automatic redemption and redemption at our option as an “early redemption.” The applicable pricing supplement will set forth the terms specific to any early redemption applicable to the securities.

The key dates of the securities will be specified in the applicable pricing supplement, subject to postponement as set forth under “Description of the Securities—Postponement of calculation dates,” herein. Unless previously accelerated, redeemed, or purchased by us and cancelled, the securities will be redeemed on the maturity date for an amount in cash determined as set forth in the applicable pricing supplement.

Please refer to “Risk Factors” beginning on page PS-3 of this product supplement for risks related to an investment in the securities.

Neither the Securities and Exchange Commission (“SEC”) nor any state securities commission has approved or disapproved of these securities or determined if this product supplement or the prospectus supplement or prospectus to which it relates is truthful or complete. Any representation to the contrary is a criminal offense.

The securities are not deposit liabilities and are not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other governmental agency of the United States, Switzerland or any other jurisdiction.

Summary

The following is a summary of the terms of the securities and other information that you should consider before deciding to invest in the securities. You should read the relevant offering documents, including this product supplement, carefully to understand fully the terms of the securities and other considerations that are important in making a decision about investing in the securities. You should, in particular, review the “Risk Factors” section of this product supplement, which sets forth a number of risks related to the securities. All of the information set forth below is qualified in its entirety by the detailed explanations set forth and incorporated by reference elsewhere in this product supplement, any accompanying underlying supplements or other product supplements, as applicable, the prospectus supplement and prospectus. The pricing supplement for the securities will contain certain specific information and terms of that offering and may also add, update or change the information contained in the other offering documents. If any information in the applicable pricing supplement is inconsistent with the other offering documents, you should rely on the information in that pricing supplement. It is important for you to consider the information contained in all the offering documents in making your investment decision.

What are the securities and how are payments on the securities determined?

The securities are senior unsecured medium-term notes issued by us, the return on which is linked to the positive or inverse performance of one or more underlyings or a basket, as specified in the applicable pricing supplement. Subject to acceleration and early redemption, if applicable, any payment will be determined as set forth in the applicable pricing supplement.

Any payment due on the securities is subject to our ability to pay our obligations as they become due.

Do the securities guarantee the return of my investment?

The payment of any amount due on the securities will be determined pursuant to the terms described in the applicable pricing supplement. The applicable pricing supplement will specify the circumstances in which you could lose some or all of your investment, as applicable. In addition, any payment on the securities is subject to our ability to pay our obligations as they become due.

Will I receive coupons on the securities?

Are there risks involved in investing in the securities?

An investment in the securities involves risks. Please see the “Risk Factors” section beginning on page PS-3.

What will I receive if the securities are redeemed prior to maturity?

If applicable, the securities may be redeemed prior to maturity under circumstances as set forth in the applicable pricing supplement. If the securities are redeemed prior to the maturity date, you will receive only the amount specified in the applicable pricing supplement, and any applicable coupons to, and including, the early redemption date. In this case, you will lose the opportunity to be paid coupons, if any, or participate in the performance of any underlying or the basket from the early redemption date to the originally scheduled maturity date. For additional information, please refer to “Description of the Securities — Early redemption; defeasance” herein.

Will there be an active trading market in the securities?

The securities will not be listed on any securities exchange. Accordingly, there is no assurance that a liquid trading market will develop for the securities. If Credit Suisse (or an affiliate) bids for your securities in secondary market transactions, which we are not obligated to do, the secondary market price (and the value used for account statements or otherwise) may be higher or lower than the price to public and the estimated value of the securities on the trade date. The estimated value of the securities on the cover of the applicable pricing supplement does not represent a minimum price at which we would be willing to buy the securities in the secondary market (if any exists) at any time. The secondary market price of your securities at any time cannot be predicted and will reflect the then-current estimated value determined by reference to our pricing models and other factors, including our internal funding rate, customary bid and ask spreads and other transaction costs, changes in market conditions and deterioration or improvement in our

creditworthiness. See “Risk Factors— The estimated value of the securities on the trade date may be less than the price to public.” In circumstances where our internal funding rate is higher than our secondary market credit spreads, our secondary market bid for your securities could be less favorable than what other dealers might bid because, assuming all else is equal, we use the higher internal funding rate to price the securities and other dealers might use the lower secondary market credit spread to price them. Furthermore, assuming no change in market conditions from the trade date, the secondary market price of your securities will be lower than the price to public because it will not include the agent’s discounts or commissions and hedging and other transaction costs. If you sell your securities to a dealer in a secondary market transaction, the dealer may impose an additional discount or commission, and as a result the price you receive on your securities may be lower than the price at which we may repurchase the securities from such dealer.

We (or an affiliate) may initially post a bid to repurchase the securities from you at a price that will exceed the then-current estimated value of the securities. That higher price reflects our projected profit and costs, which may include discounts and commissions that were included in the price to public, and that higher price may also be initially used for account statements or otherwise. We (or our affiliate) may offer to pay this higher price, for your benefit, but the amount of any excess over the then-current estimated value will be temporary and is expected to decline over a period of time to be specified in the applicable pricing supplement.

The securities are not designed to be short-term trading instruments and any sale prior to maturity could result in a substantial loss to you. You should be willing and able to hold your securities to maturity.

Will the securities be distributed by affiliates of the Issuer?

Credit Suisse Securities (USA) LLC (“CSSU”) is one of our wholly owned subsidiaries. Any offering in which CSSU participates will be conducted in compliance with the requirements of FINRA Rule 5121 regarding a FINRA member firm’s distribution of the securities of an affiliate and related conflicts of interest. In accordance with FINRA Rule 5121, CSSU may not sell the securities to any of its discretionary accounts without the prior written approval of the customer. Please see the section entitled “Underwriting (Conflicts of Interest)” herein.

What are the United States federal income tax consequences of investing in the securities?

Please refer to “United States Federal Tax Considerations” herein for a discussion of certain United States federal income tax considerations for making an investment in the securities.

A purchase of the securities involves risks. This section describes significant risks relating to the securities. You should read the following information about these risks, together with the other information contained or incorporated by reference in the other offering documents before investing in the securities.

Investors are dependent on Credit Suisse’s ability to pay all amounts due on the securities. Therefore, if we were to default on our obligations, you may not receive any amounts owed to you under the securities. 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 value of the securities prior to maturity.

The securities differ from conventional debt securities and do not guarantee the return of your investment

The payment of any amount due on the securities will be determined pursuant to the terms described in the applicable pricing supplement. You may receive less at maturity or upon early redemption, than you originally invested in the securities, or you may receive nothing. The applicable pricing supplement will specify the circumstances in which you could lose some or all of your investment.

Your actual yield on the securities may be different from the amount of any payment you receive on the securities in real value terms

Regardless of the amount of any payment you receive on the securities, you may nevertheless suffer a loss on your investment in the securities in real value terms. This is because inflation may cause the real value of any payment you receive on the securities to be less at maturity or upon early redemption, if applicable, than it is at the time you invest, and because an investment in the securities represents a forgone opportunity to invest in an alternative asset that does generate a positive return in real value terms. You should carefully consider whether an investment that may result in a return that is lower than the return on alternative investments is appropriate for you.

The estimated value of the securities on the trade date may be less than the price to public

The initial estimated value of your securities on the trade date (as determined by reference to our pricing models and our internal funding rate) may be significantly less than the original price to public. The price to public of the securities includes the agent’s discounts or commissions as well as transaction costs, such as expenses incurred to create, document and market the securities and the cost of hedging our risks as issuer of the securities through one or more of our affiliates (which includes a projected profit). These costs will be effectively borne by you as an investor in the securities. These amounts will be retained by Credit Suisse or our affiliates in connection with our structuring and offering of the securities (except to the extent discounts or commissions are reallowed to other broker-dealers or any costs are paid to third parties).

On the trade date, we value the components of the securities in accordance with our pricing models. These include a fixed income component valued using our internal funding rate, and individual option components valued using proprietary pricing models dependent on inputs such as volatility, correlation, dividend rates, interest rates and other factors, including assumptions about future market events and/or environments. These inputs may be market-observable or may be based on assumptions made by us in our discretionary judgment. As such, the payout on the securities can be replicated using a combination of these components and the value of these components, as determined by us using our pricing models, will impact the terms of the securities at issuance. Our option valuation models are proprietary. Our pricing models take into account factors such as interest rates, volatility and the time to maturity of the securities, and they rely in part on certain assumptions about future events, which may prove to be incorrect.

Because Credit Suisse’s pricing models may differ from other issuers’ valuation models, and because funding rates taken into account by other issuers may vary materially from the rates used by Credit Suisse (even among issuers with similar creditworthiness), our estimated value at any time may not be comparable to the estimated values of similar securities of other issuers.

Our internal funding rate may negatively affect the value of the securities

The internal funding rate we use in structuring notes (such as these securities) is typically lower than the interest rate that is reflected in the yield on our conventional debt securities of similar maturity in the secondary market (our “secondary market credit spreads”). If, on the trade date, our internal funding rate is lower than our secondary market credit spreads, we expect that the economic terms of the securities will generally be less favorable to you than they would have been if our secondary market credit spread had been used in structuring the securities. We will also use our internal funding rate to determine the price of the securities if we post a bid to repurchase your securities in secondary market transactions. See “— Secondary market prices” below.

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 is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities when you wish to do so. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which Credit Suisse (or its affiliates) is willing to buy the securities. If you have to sell your securities prior to maturity, you may not be able to do so or you may be forced to sell your securities at a substantial loss. You should be willing and able to hold your securities to maturity.

Secondary market prices, if any, for the securities cannot be predicted

If Credit Suisse (or an affiliate) bids for your securities in secondary market transactions, which we are not obligated to do, this secondary market price (and the value used for account statements or otherwise) may be higher or lower than the price to public and the estimated value of the securities on the trade date. The estimated value of the securities, which will be disclosed on the cover of the applicable pricing supplement, does not represent a minimum price at which we would be willing to buy the securities in the secondary market (if any exists) at any time. The secondary market price of your securities at any time cannot be predicted and will reflect the then-current estimated value determined by reference to our pricing models, the related inputs and other factors, including our internal funding rate, customary bid and ask spreads and other transaction costs, changes in market conditions and deterioration or improvement in our creditworthiness. In circumstances where our internal funding rate is higher than our secondary market credit spreads, our secondary market bid for your securities could be less favorable than what other dealers might bid because, assuming all else is equal, we use the higher internal funding rate to price the securities and other dealers might use the lower secondary market credit spread to price them. Furthermore, assuming no change in market conditions from the trade date, the secondary market price of your securities will be lower than the price to public because it will not include the agent’s discounts or commissions and hedging and other transaction costs. If you sell your securities to a dealer in a secondary market transaction, the dealer may impose an additional discount or commission and, as a result, the price you receive on your securities may be lower than the price at which we may repurchase the securities from such dealer.

As a Swiss bank, Credit Suisse is subject to regulation by governmental agencies, supervisory authorities and self-regulatory organizations in Switzerland. Such regulation is increasingly more extensive and complex and subjects Credit Suisse to risks. For example, pursuant to Swiss banking laws, the Swiss Financial Market Supervisory Authority (“FINMA”) may open resolution proceedings if there are justified concerns that Credit Suisse is over-indebted, has serious liquidity problems or no longer fulfills capital adequacy requirements. FINMA has broad powers and discretion in the case of resolution proceedings, which include the power to convert debt instruments and other liabilities of Credit Suisse into equity and/or cancel such liabilities in whole or in part. If one or more of these measures were imposed, such measures may adversely affect the terms and market value of the securities and/or the ability of Credit Suisse to make payments thereunder, and you may not receive any amounts owed to you under the securities.

Unpredictable economic and market factors may affect the value of the securities prior to maturity

The value of the securities on the trade date may be estimated by using a combination of the components described in the risk factor “The estimated value of the securities on the trade date may be less than the price to public” above. Similarly, the value of the securities prior to maturity may be influenced by a number of factors that impact the value of such components generally, like fixed income securities and options, such as:

Some or all of these factors may influence the price that you will receive if you choose to sell your securities prior to maturity. The impact of any of the factors set forth above may compound or offset, in whole or in part, the effects of any change resulting from any other factor(s).

We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and as agent of the issuer for the offering of the securities, hedging our obligations under the securities and determining their estimated value. In performing these duties, the economic interests of us and our affiliates may be adverse to your interests as an investor in the securities. For example, we, CSSU and/or any other affiliate of ours may, from time to time, buy or sell futures contracts and/or other derivative instruments linked or related to any underlying(s) or for our or their own accounts in connection with our or their normal business practices. These transactions could affect the level(s) of such underlying(s), and thus, the value of the securities.

In addition, because Credit Suisse International, which is initially acting as the calculation agent for the securities, is an affiliate of ours, conflicts of interest may exist between the calculation agent and you, including with respect to certain determinations and judgments that the calculation agent must make in determining any amounts due to you.

We or our affiliates may also currently, or from time to time in the future, publish research reports or otherwise express opinions regarding any commodities included in an underlying, and these reports or opinions may or may not recommend that investors buy or hold such commodities. As a prospective purchaser of the securities, you should undertake an independent investigation of the underlying(s) that in your judgment is appropriate to make an informed decision with respect to an investment in the securities.

Further, hedging activities may adversely affect any payment on, and the value of, the securities. Any profit in connection with such hedging activities will be in addition to any other compensation that we or our affiliates may receive in connection with the sale of the securities, which creates an additional incentive to sell the securities to you. In addition, we or one of our affiliates may serve as issuer, agent or underwriter for additional issuances of securities with returns linked to (or related to spreads between) any underlying(s). By introducing competing products into the marketplace in this manner, we or one or more of our affiliates could adversely affect the value of the securities.

The calculation agent, which is an affiliate of ours, will make important determinations with respect to the securities

As calculation agent, Credit Suisse International, our affiliate, will determine, among other things, any value required to be determined under the securities and any amounts owed to you under the terms of the securities. In addition, if certain events occur, Credit Suisse International will be required to make certain discretionary judgments that could significantly affect what you receive at maturity or, if applicable, any other payment owed to you under the securities. In making these judgments, Credit Suisse International’s interests as an affiliate of ours could be adverse to your interests as a holder of the securities. Such judgments could include, among other things:

Any of these determinations made by Credit Suisse International, in its capacity as calculation agent, may adversely affect any payment owed to you under the securities.

The offering of any securities does not constitute an expression of our views about, or a recommendation to invest in, any underlying or basket

The offering of any securities is not an expression of our views about how any underlying(s) or basket will perform over the term of the securities and should not be misconstrued as a recommendation to invest (directly or indirectly, by taking a long or short position) in the commodities included in, or instruments linked or related to, any underlying(s) or basket. As a global financial institution, we and our affiliates may, and often do, have positions (long, short or both) in the commodities included in, or instruments linked or related to, any underlying(s) or basket that may conflict with an investment in the securities. See the risk factor “— There may be conflicts of interest” above for examples of potentially conflicting positions we may have. In addition, our affiliates or agents may publish research reports from time to time on financial markets and other matters that may influence the value of the securities, and we may express opinions or provide recommendations that are inconsistent with purchasing or holding the securities. Any research, opinions or recommendations expressed by us or our affiliates or agents may not be consistent with other such research, opinions or recommendations and may be modified from time to time without notice. Any such research, opinions or recommendations could affect the level(s) of the underlying(s) or the basket and, therefore, the value of the securities. You should undertake an independent determination of whether an investment in the securities is suitable for you in light of your particular situation, including your specific investment objectives, risk tolerance and financial resources.

Holdings and future sales of the securities by our affiliates may affect the value of the securities

Certain of our affiliates may purchase some of the securities for investment. As a result, upon completion of an offering, our affiliates may own up to approximately 15% of the securities offered in such offering. Circumstances may occur in which our interests, or those of our affiliates, could be in conflict with your interests. In addition, if a substantial portion of the securities held by our affiliates were to be offered for sale in the secondary market, if any, following such an offering, the value of the securities may fall. The negative effect of such sales on the prices of the securities could be pronounced because secondary trading in the securities is likely to be limited and illiquid.

We may engage in hedging and trading in the commodities included in any underlying(s) or in instruments linked or related to any underlying(s)

While the securities are outstanding, we or any of our affiliates may carry out hedging activities related to the securities, including trading in commodities included in any underlying(s) or in instruments linked or related to any underlying(s). Even if there is an active trading market, there may not be enough liquidity to allow the shares of such underlyings to trade easily, at which point the value of the securities may be adversely affected.

The U.S. federal tax consequences of an investment in the securities may be uncertain

There is no direct legal authority regarding the proper U.S. federal tax treatment of certain securities that may be offered under this product supplement, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of those securities are uncertain, and the IRS or a court might not agree with the treatment of them described in “United States Federal Tax Considerations.” If the IRS were successful in asserting an alternative treatment for the securities, the tax consequences (including, for non-U.S. investors, the withholding tax consequences) of ownership and disposition of the securities might be materially and adversely affected.

As described below under “United States Federal Tax Considerations,” the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. In addition, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. You should review carefully the section of this product supplement entitled “United States Federal Tax Considerations.” You should also consult your tax advisor regarding the U.S. federal tax consequences of an investment in the securities, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The price at which you will be able to sell your securities prior to maturity (including to us or our affiliates), if at all, may be at a substantial discount from their principal amount, even in cases where the underlying(s) or the basket has appreciated during the term of the securities. The potential returns described in the applicable pricing supplement assume that your securities, which are not designed to be short-term trading instruments, are held to maturity.

The applicable pricing supplement will specify whether, and under what conditions, coupons will be paid on the securities and the applicable amount of any such coupons and/or rate per annum, as well as any specific terms and conditions relating to, among other things, the calculation, frequency and payment of such coupons. If the applicable pricing supplement does not provide for the payment of coupons, you will not receive any coupons over the term of the securities. Even if the securities do provide for coupons, the securities may not provide for regular fixed interest payments. The amount and the total number of coupons you receive over the term of the securities, if any, may depend on the performance of one or more underlyings or basket during the term of the securities. In this case, the securities would not be a suitable investment for investors who require regular fixed income payments, since the amount and total number of coupons paid is variable and the total amount of coupons paid may be zero.

In addition, if interest rates generally increase over the term of the securities, it is more likely that the coupon, if any, could be less than the yield one might receive based on market rates at that time. This would have the further effect of decreasing the value of your securities both nominally in terms of below-market coupons and in real value terms. Furthermore, if the securities do not pay regular coupons, it is possible that you will not receive some or all of the contingent coupons over the term of the securities, and still lose your principal amount. Even if you do receive

some or all of your principal amount at maturity or upon early redemption, if applicable, you will not be compensated for the time value of money. The securities are not designed to be short-term investments, so you should carefully consider these risks before investing.

If we pay coupons on the securities, the yield on the securities may be lower than the return on an ordinary debt security with similar maturity

If applicable, we will pay coupons on the securities subject to the terms and conditions specified in such pricing supplement. The rate per annum of such coupons may be lower than the rate you could earn on ordinary coupon-bearing debt securities of ours with similar maturities. As a result, you could receive less with respect to the securities than you could have earned on ordinary coupon-bearing debt securities of ours with similar maturities.

More favorable terms to you on the securities may be associated with greater expected volatility of the relevant underlying(s), and therefore, can indicate a greater risk of loss

“Volatility” refers to the frequency and magnitude of changes in the level of an underlying. If the securities provide for payment of coupons with the potential to result in a higher yield than the yield on our conventional debt securities of the same maturity, you should understand that, the greater the expected volatility with respect to the underlyings on the trade date, the higher the expectation is as of the trade date that changes in the levels of the underlyings could result in you (i) receiving fewer coupons, if any, over the term of the securities, resulting in a below-market yield that is lower, and perhaps significantly lower, than the yield on our conventional debt securities of the same maturity and (ii) losing some or all of your principal amount at maturity. These greater expected risks will generally be reflected in a higher potential yield on the securities as compared to conventional debt securities of ours with similar maturities, or in more favorable terms than for similar securities linked to the performance of an underlying with a lower expected volatility as of the trade date. You should therefore understand that a relatively higher potential yield on the securities may indicate an increased risk of loss. In addition, the volatility of any underlying can change significantly over the term of the securities, which could cause the level of such underlying to rise or fall sharply. This could result in a significant loss of principal for investors in the securities.

There may be a maximum return on the securities, regardless of the performance of any underlying or basket. For example, the securities may be subject to a maximum return or a fixed payment percentage. Under these circumstances, the redemption amount may be limited by such maximum return or fixed payment percentage, even if the performance of the relevant underlying or the basket is greater than such maximum return or fixed payment percentage. Alternatively, the securities may be designed to pay a maximum of the principal amount of your securities plus applicable coupons, if any, regardless of the performance of any underlying or basket. You should not invest in securities that have a maximum return if you seek to participate in the full performance of any relevant underlying or basket.

Securities with a downside leverage factor embedded in their payment terms are highly risky

Your return on the securities at maturity may be multiplied by a downside leverage factor that is greater than 1.0, or 100%. Under these terms, any decrease in the level of any underlying or basket may result in a magnified loss of your investment. You should not invest in such securities unless you fully understand the risks associated with the downside leverage factor embedded in their payment terms.

For example, for securities with a buffer, if the final level is less than the buffer level, you will be fully exposed to any depreciation in the level of the relevant underlying or basket beyond the buffer level. If the applicable pricing supplement specifies a downside leverage factor greater than 1.0 or 100% then you will be fully exposed to any depreciation beyond the buffer level on a leveraged basis. Accordingly, to the extent the downside leverage factor is greater than 1.0 or 100% and the depreciation in the relevant underlying or the basket exceeds the buffer level, the loss on a percentage basis will exceed the actual depreciation beyond the buffer level on a percentage basis, which will in turn amplify the negative impact on your payment at maturity. In this case, any downside protection offered by the buffer may be entirely eliminated.

The securities may be subject to early redemption, which would limit your opportunity to benefit from any future performance of the underlying(s) or the basket or to be paid coupons, if any, over the full term of the securities

The applicable pricing supplement may specify that the securities are subject to an early redemption at our option or upon the occurrence of a specified event. If the securities are redeemed prior to the maturity date, you will receive only the applicable amount as set forth in the applicable pricing supplement. In this case, you will not benefit from any future performance of the underlying(s) or the basket and, if coupons may be paid on the securities, you would lose the opportunity to continue to be paid coupons, if any, from the early redemption date to the scheduled maturity date.

If the securities are redeemed prior to the maturity date, you may be unable to invest in other securities with a similar level of risk that provide you with the opportunity to be paid the same coupons as the securities.

If the securities are subject to a knock-in event, you may lose some or all of your investment if a knock-in event occurs with respect to any underlying or basket. The applicable pricing supplement will specify the circumstances under which a knock-in event can occur.

If the securities are subject to intraday monitoring, it is possible that a knock-in event could occur under circumstances that would not result in the occurrence of a knock-in event if the securities were instead subject to closing level monitoring

The securities may be subject to intraday monitoring or daily closing level monitoring. In the case of intraday monitoring, the level of the relevant underlying or the basket at any time on any trading day during an observation period or on the relevant valuation date(s) will be taken into account when determining the payment on the securities. In the case of daily closing level monitoring the closing level of the relevant underlying or basket on any trading day during an observation period or on the relevant valuation date(s), as applicable, will be taken into account when determining the payment on the securities. If the securities are subject to a knock-in event with intraday monitoring, a knock-in event will occur if the level of the relevant underlying or the basket at any time on any trading day during an observation period or on the relevant valuation date(s), as applicable, is less than (or equal to, as applicable) the knock-in level for such underlying or basket, even if the closing level of such underlying or basket is greater than (or equal to) the knock-in level on that trading day. If the securities are subject to a knock-in event with daily closing level monitoring, a knock-in event will occur if the closing level of the relevant underlying or the basket on any trading day during an observation period or on the relevant valuation date(s), as applicable, is less than (or equal to, as applicable) the knock-in level for such underlying or basket, even if the closing level of such underlying or basket is greater than (or equal to) the knock-in level on any other trading day during the observation period or on the relevant valuation date(s), as applicable.

The initial level(s) of the relevant underlying(s) or the basket may be determined on a date prior to or later than the trade date or may be intraday level(s), rather than closing level(s), of the underlying(s) on the trade date

If so specified in the applicable pricing supplement, the initial level(s) of any underlying(s) or the basket may be determined on a date prior to or later than the trade date or may be intraday level(s), rather than closing level(s), of the underlying(s) on the trade date. For example, the applicable pricing supplement may specify that the initial level for an underlying or basket was determined on a date prior to the trade date. Under these circumstances, you will be exposed to any fluctuations in the value of the underlying(s) or the basket beginning on the date on which the initial level(s) are set to the trade date. Alternatively, the applicable pricing supplement may specify that the initial level for an underlying or basket will be determined based on the lowest level or the average level for such underlying or basket during the period from the trade date to a specified future date, in which case, you will not know the initial level of such underlying or basket until a date later than the trade date. The initial level(s) of the underlying(s) may also be intraday level(s) of the underlying(s) on the trade date. In such circumstances, the initial level(s) of the underlying(s) will be determined by the calculation agent in its sole discretion and may be higher or lower than the closing level(s) of the underlying(s) on the trade date. In any of these cases, the level(s) of the underlying(s) at the time you purchase the securities may be higher or lower than the initial level(s) of the underlying(s) and may result

in their being a greater likelihood of loss of your investment in the securities than if the initial level(s) of the underlying(s) were determined on the trade date or another date or time.

In the case of securities linked to a basket, the basket components may not be equally weighted

In the case of securities linked to a basket, the basket components may have different weights used in determining the level of such basket. One consequence of an unequal weighting of basket components is that, if a higher-weighted basket component performs poorly while a lower-weighted basket component performs well, the level of such basket will reflect the poor performance of the higher-weighted basket component to a greater extent than it reflects the stronger performance of the lower-weighted basket component. As such, the unequal weighting of basket components may have an adverse effect on the value of the securities and your payment at maturity.

Correlation (or the lack thereof) could have an adverse effect on your return on the securities

In the case of securities linked to a basket, movements in the levels of the basket components may not correlate with each other. At a time when the level(s) of one or more of the basket components increase, the level(s) of one or more of the other basket components may not increase as much or may even decline. Therefore, in calculating the basket return, increases in the level(s) of one or more of the basket components may be moderated, or more than offset, by lesser increases or declines in the level(s) of one or more of the other basket components. On the other hand, changes in the levels of the basket components may become highly correlated during periods of decline in the value of the commodities included in such basket components. This may occur because of events that have broad effects on markets generally or for other reasons. If changes in the levels of the basket components become correlated during periods of decline, a decline in the level of any single basket component may not be offset by the performance of the other basket components and, in fact, each basket component may contribute individually to an overall decline in the level of the basket.

In the case of securities linked to the worst performing of more than one underlying, if the performance of the underlyings exhibit no relationship to each other, it is more likely that one of the underlyings will cause the securities to perform poorly. However, if the commodities included in the underlyings tend to be related such that the performance of the underlyings are correlated, then it is less likely that only one of the underlyings will cause the securities to perform poorly. To the extent that the underlyings represent different market segments or market sectors, the risk of one of the underlyings performing poorly is greater. As a result, by investing in such securities, you will be exposed to the market risk of the commodities included in the underlyings.

It is impossible to predict what the relationships between the underlyings will be over the term of the securities.

In the case of securities linked to the individual performance of more than one underlying, you may be fully exposed to the risk of fluctuations in the levels of each underlying

If the securities are linked to the individual performance of more than one underlying, you will be exposed to the risk of fluctuations in the levels of each underlying separately. Unlike securities that are linked to a basket, where risk is mitigated and diversified among all of the basket components, the amount of any payment on your securities may depend solely on the performance of the worst performing of the underlyings. As such, you will bear the full risk that any of the underlyings will perform poorly.

An investment in the securities is not the same as a direct investment in the commodities included in any underlying

Your return on the securities will not reflect the return you would have realized on a direct investment in the commodities included in any underlying. The calculation agent will calculate the amount payable to you at maturity by reference to the level(s) of the underlying(s) on the relevant valuation date(s), and will not include the amount of any payments or other distributions with respect to any underlying(s). Therefore, the return on your investment, which will be determined as set forth in the applicable pricing supplement, is not the same as the total return based on the purchase of any commodities included in any underlying or basket component, as applicable.

If the level of any underlying or basket changes, the market value of your securities may not change in the same manner

Owning the securities is not the same as owning the commodities included in any underlying or basket component, as applicable. For example, if the level of any underlying or basket on any day has increased (or, in the case of securities linked to the inverse performance of such underlying or basket, has decreased), the value of the securities may not increase comparably, if at all, on such day and the value of the securities may even decline. Accordingly, changes in the level(s) of any underlying(s) or basket may not result in a comparable change in the value of the securities.

If the securities are linked to multiple underlyings or a basket and the commodities included in such underlyings or basket components, as applicable, are concentrated in a single or limited number of asset classes, market sectors, market segments or geographical regions, you will not benefit from the advantages of a diversified investment. Instead, you will bear the risks of a concentrated investment, including the risk of greater volatility than may be experienced in connection with a diversified investment, and the value of the securities may be more adversely affected by a single economic, political, regulatory or other occurrence affecting a single market sector, market segment or geographical region. You should be aware that other investments may be more diversified than the securities in terms of the number and variety of market sectors and segments, asset classes and/or geographical regions represented.

In addition, the fact that the securities may be linked to multiple underlyings or a basket does not mean that the securities represent a diversified investment. Although the underlyings or basket components may differ in certain respects, they may bear similarities that cause them to perform in similar ways. For example, securities linked to a basket of indices that track U.S. crude oil futures contracts will have concentrated exposure to the U.S. crude oil markets, and such basket components may respond in similar ways to economic events that affect the U.S. crude oil markets generally. Furthermore, the securities are subject to the credit risk of Credit Suisse. No amount of diversification across basket components will offset the risk that we may default on our obligations, including our obligations under the terms of the securities.

The calculation agent may, in its discretion, determine that markets have been affected in a manner that prevents it from properly valuing any underlying(s) on any day during the term of the securities, or from calculating the amount of any payment due to you on the securities. These events may include disruptions or suspensions of trading in the markets as a whole. If the calculation agent determines that a market disruption event has occurred or that any calculation date is not a trading day, it is possible that one or more calculation date(s), the maturity date, the trade date and/or any other relevant dates as set forth in the applicable pricing supplement will be postponed, and your return could be adversely affected. No coupons or other payment will be payable as a result of such postponement. For additional information, see “Description of the Securities — Market Disruption Events” below.

Historical performance of any underlying or basket is not indicative of future performance

The future performance of any underlying(s) or basket cannot be predicted based on its historical performance. We cannot guarantee that the future levels or the final level(s) of any underlying(s) or basket will result in a positive return on your overall investment in the securities.

The final level for any underlying or basket may be less than (or, in the case of securities linked to the inverse performance of such underlying or basket, may be greater than) its closing levels at other times during the term of the securities

The final level for any underlying(s) or basket will be calculated based on the closing level of such underlying(s) or basket on the relevant valuation date(s). The final level could be lower than (or, in the case of

securities linked to the inverse performance of an underlying or basket, may be greater than) the closing levels for such underlying(s) or basket at other times during the term of the securities. The impact of this difference on your return on the securities could be substantial if there is significant volatility in the closing levels of such underlying(s) or basket during the term of the securities, and in particular, if there is a significant increase or decrease in such closing levels around the time of a valuation date. Accordingly, you may receive a lower payment at maturity than you would have received if you had invested directly in the commodities included in such underlying(s) or basket component(s), as applicable.

We cannot assure you that any public information provided about any underlying is accurate or complete

All disclosure relating to the underlying(s) contained in the applicable pricing supplement and/or any accompanying underlying supplement(s) will be derived from publicly available documents and other publicly available information. We have not participated, and will not participate, in the preparation of such documents and have not made any due diligence inquiry with respect to any underlying(s) in connection with the offering of the securities. We do not make any representation that such publicly available documents or any other publicly available information regarding any underlying is accurate or complete. We are not responsible for any public disclosure of information by any index creator, index calculation agent or sponsor of any underlying (an “index sponsor”), whether contained in filings with the SEC or otherwise. Furthermore, we cannot give any assurance that all events occurring prior to the date of the applicable pricing supplement, including events that would affect the accuracy or completeness of any public information or filings of any index sponsor, or the level(s) of any underlying(s), will have been publicly disclosed. Subsequent disclosure of any of those events or the disclosure of, or failure to disclose, material future events concerning any underlying(s) could affect the amount of any payment due on the securities. Any prospective purchaser of the securities should undertake an independent investigation of the underlying(s) to which the securities are linked as in its judgment is appropriate to make an informed decision with respect to an investment in the securities.

We and our affiliates generally do not have any affiliation with, and cannot control the actions of, any index sponsor and are not responsible for their public disclosure of information

We and our affiliates generally are not affiliated with any index sponsor in any way and have no ability to control or predict their actions, including any errors in, or discontinuance of, disclosure regarding their methods or policies. Actions by any index sponsor may have an adverse effect on the level of the relevant underlying and, consequently, the value of the securities.

Neither we nor any of our affiliates assumes any responsibility for the accuracy or adequacy of any information about any underlying(s) contained in any public disclosure of information. You, as an investor in the securities, should make your own investigation into the underlying(s).

You will have no rights against any index sponsor. The securities are not sponsored, endorsed, sold or promoted by any index sponsor. No index sponsor has passed on the legality or suitability of, or the accuracy or adequacy of any descriptions or disclosure relating to, the securities. No index sponsor makes any representation or warranty, express or implied, to you or to any member of the public regarding the advisability of investing in securities generally or in the securities we are offering to you in particular, or the ability of any underlying(s) to track general market performance or the performance of any market sector(s).

An index sponsor’s only relationship to us is with regard to the licensing of trademarks, service marks and/or trade names as well as the use of the relevant underlying, which is determined, composed and calculated by such index sponsor without regard to us, the securities or your interests as an investor in the securities. No index sponsor is responsible for, and none of them has participated in the determination of, the timing, prices or quantities of the securities to be issued or in the determination or calculation of the equation by which any amount due to you on the securities is to be determined. No index sponsor has any liability in connection with the administration, marketing or trading of the securities. No index sponsor has any obligation to take our or your interests into consideration for any reason.

The sponsor of any underlying can add, delete or substitute the commodities included in such underlying, make other methodological changes that could affect the level of such underlying, or discontinue or suspend the calculation or dissemination of such underlying at any time. If one or more of these events occurs, the calculation of the redemption amount payable at maturity or upon early redemption, if applicable, will be adjusted to reflect such event(s). Please refer to “Description of the Securities — Changes to the calculation of an underlying” Any of these actions could adversely affect the amount payable with respect to the securities and/or the value of the securities.

An underlying may be affected by exchange rates and we have no control over exchange rates

Foreign exchange rates can either float or be fixed by sovereign governments. Exchange rates of the currencies used by most economically developed nations are permitted to fluctuate in value relative to the U.S. dollar and to each other. However, from time to time, governments and, in the case of countries using the euro, the European Central Bank may use a variety of techniques, such as intervention by a central bank, the imposition of regulatory controls or taxes, or changes in interest rates, to influence the exchange rates of their currencies. Governments may also issue a new currency to replace an existing currency or alter the exchange rate or relative exchange characteristics by a devaluation or revaluation of a currency. These governmental actions could change or interfere with currency valuations and currency fluctuations that would otherwise occur in response to economic forces, as well as in response to the movement of currencies across borders. As a consequence, these governmental actions could adversely affect an investment in a security that is linked, in whole or in part, to any underlying that tracks commodities, whether or not denominated in a foreign currency. We will not make any adjustment or change to the terms of the securities in the event that exchange rates should become fixed, in response to any devaluation or revaluation of a currency or any imposition of exchange or other regulatory controls or taxes, or in the event of other developments affecting the U.S. dollar or any relevant foreign currency.

The securities may be linked to a price return index or an excess return index, rather than a total return index

The securities may be linked to an underlying that is a price return index or an excess return index, rather than a total return index. A price return index is designed to reflect only the price movements of the commodities included in such underlying, while a total return index reflects the returns that would potentially accrue from a hypothetical investment in such commodities. By contrast, an excess return index reflects the same returns reflected by the total return version of such index, but minus the cost of the interest paid to borrow the funds to invest in the total return version of such index. Therefore, any payment due to you with respect to securities linked to a price return index could be less than such payment would have been if the securities were linked to a total return index and any payment due to you with respect to securities linked to an excess return index will be less than such payment would have been if the securities were linked to a total return index or, possibly, a price return index.

Even if the commodities included in an underlying are all part of the same industry, market sector or asset class, such commodities are not necessarily representative of that industry, market sector or asset class

Even if an underlying purports to be representative of a particular industry, market sector or asset class, the performance of such underlying may not correlate with the performance of that entire industry, market sector or asset class. An underlying may decline even if the representative industry, market sector or asset class as a whole rises in value. The commodities included in an underlying may not necessarily be representative of such industry, market sector or asset class because the universe of such commodities may be incomplete or become outdated over time.

We have been granted, or will be granted, a non-exclusive right to use each underlying and related trademarks in connection with the offering of the securities. If we breach our obligations under any license, the relevant index sponsor may have the right to terminate such license. If an index sponsor chooses to terminate a license agreement with us, we may no longer have the right under the terms of the license agreement to use the relevant underlying and related trademarks in connection with the securities until their maturity. If our right to use any underlying is

suspended or terminated, it may become difficult for us to determine the level of such underlying and, consequently, the coupons, if any, payment at maturity or upon early redemption, if applicable, or any other amounts payable to you on the securities. In such case, the calculation agent will determine, in its sole discretion, the relevant level of such underlying and/or the fair value of the securities.

Levels of any underlying or commodities included in any underlying may change unpredictably and affect the value of the securities in unanticipated ways

Fluctuations in the levels of any underlying or any commodities included in such underlying may have a material adverse effect on the value of the securities and your return on an investment in the securities. The levels of such underlyings or commodities are affected by numerous factors, including: (i) changes in supply and demand relationships; (ii) governmental programs and policies; (iii) national and international political and economic events; (iv) expectations of and changes in interest, inflation and exchange rates; (iv) speculation and trading activities in commodities included in such underlyings and related contracts; (v) general weather conditions; and (vi) trade, fiscal, monetary and exchange control policies. The demand for many commodities is also highly cyclical. These factors, some of which are specific to the market for each such commodity, as discussed below, may cause the value of any underlying to move in inconsistent directions at inconsistent rates, affecting the value of the securities. It is not possible to predict the aggregate effect of all or any combination of these factors.

The securities may be adversely affected by “negative roll yields” in “contango” markets

An underlying may track the value of hypothetical or actual positions in futures contracts on physical commodities, where each position is “rolled” periodically out of one futures contract as the expiration date of that futures contract approaches and into another futures contract on the same underlying commodity with a later expiration date. Unlike stocks, which typically entitle the holder to a continuing stake in a corporation, commodity futures specify a certain future date for cash settlement or the physical delivery of a commodity. In order to avoid settlement or physical delivery and maintain continuing exposure to commodity futures, such underlying may unwind its hypothetical position in each futures contract shortly before its expiration date and replaces that position with a hypothetical or actual position in another futures contract on the same underlying commodity with a later expiration date. For example, a futures contract entered into in August may specify a September expiration. As the September expiration date approaches, the futures contract expiring in September may be replaced with a futures contract on the same underlying commodity expiring in October. We refer to this process as “rolling” exposure to an expiring futures contract into another futures contract on the same underlying commodity with a later expiration date. Through this rolling process, the underlying is able to reflect continuing exposure to futures contracts on the same underlying commodities.

The rolling feature of the underlying creates the potential for a significant negative effect on the level of the underlying—which we refer to as a “negative roll yield”—that is independent of the performance of the spot prices of the underlying physical commodities tracked by the underlying. The “spot price” of a commodity is the price of that commodity for immediate delivery, as opposed to a futures price, which represents the price for delivery on a specified date in the future. The underlying would be expected to experience negative roll yield if commodity futures prices tend to be greater than the spot prices for the relevant commodities. A market where futures prices are generally greater than spot prices is referred to as a “contango” market. Futures prices on a commodity may be greater than spot prices for a variety of reasons, including costs of storing the commodity until the delivery date, financing costs and market expectations that future spot prices may be higher than current spot prices. As any commodity futures contract approaches expiration, its value will generally approach the spot price of the relevant commodity, because by expiration it will effectively represent a contract to buy or sell that commodity for immediate delivery. Therefore, if the futures market for a given commodity is in contango, then the value of a futures contract on that commodity would tend to decline over time (assuming the spot price remains unchanged), because the higher futures price would fall as it converges to the lower spot price by expiration. If the futures market for a given commodity is in contango and the spot price of that commodity remains constant, the underlying would enter into a hypothetical position in a futures contract on that commodity at the higher contango futures price and then unwind that position near the lower spot price just prior to expiration of that contract, and then enter into a hypothetical position in a new futures contract on that commodity at the higher contango futures price and unwind that position near the lower spot price, and so on over the term of the securities, all the while accumulating losses

from the erosion in value that results as the higher contango price declines toward the lower spot price. The remaining time to expiration may also be a factor. For example, a futures contract with a remaining term of one month may have a higher negative roll yield as compared to a futures contract with a remaining term of six months. Finally, some futures contracts may be in contango whereas other futures contracts on the same commodity may be in backwardation. Any of these circumstances could cause a decline in the level of an underlying and therefore the value of and return on your securities.

Prospective investors in the securities should understand that futures on the commodities underlying an underlying may have historically been in contango markets. Therefore, there is a significant risk that negative roll yields may adversely affect the level of an underlying and the return you receive on the securities. Any negative roll yield will offset any gains in the spot prices of the underlying commodities that may occur over the term of the securities, exacerbate any decline and cause a steady erosion in value if the spot prices of the underlying commodities remain relatively constant.

Holders of the securities will not benefit from regulatory protections of the Commodity Futures Trading Commission

The securities are our direct obligations. The net proceeds to be received by us from the sale of the securities will not be used to purchase or sell commodity futures or options contracts on commodity futures for the benefit of the holders of securities. An investment in the securities does not constitute an investment in commodity futures or options contracts on commodity futures, and holders of the securities will not benefit from the regulatory protections of the Commodity Futures Trading Commission (the “CFTC”) afforded to persons who trade in such contracts.

Legal and regulatory changes could adversely affect the return on and value of the securities

Futures contracts and options on futures contracts, including the futures contracts that may be tracked by an underlying, or futures contracts on an underlying itself, are subject to extensive statutes, regulations and margin requirements. The CFTC and the exchanges on which such futures contracts trade are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily limits and the suspension of trading. Furthermore, futures exchanges may have regulations designed to limit the amount of fluctuations in futures contract prices. These limits could adversely affect the market prices of futures contracts, which could adversely affect the return on and value of the securities.

In addition, the regulation of commodity transactions in the U.S. is subject to ongoing modification by government and judicial action. The effect on the value of the securities of any future regulatory change is impossible to predict, but could be substantial and adverse to the interests of holders of the securities. For example, the Dodd–Frank Wall Street Reform and Consumer Protection Act, which was enacted on July 21, 2010, requires the CFTC to establish limits on the size of the positions any person may hold in futures contracts on a commodity, options on such futures contracts and swaps that are economically equivalent to such contracts. In particular, the CFTC has proposed rules to establish position limits that will apply to specified agricultural, metals and energy futures contracts and futures, options and swaps that are economically equivalent to those futures contracts, including many of the futures contracts that may be included in an underlying. The limits will apply to a person’s combined position in futures, options and swaps on the relevant commodities. The rules, if enacted in their proposed form, may reduce liquidity in the exchange-traded market for the relevant commodity futures, which may, in turn, have an adverse effect on your payment at maturity. Market participants may decide, or be required to, sell their positions in the relevant commodity futures as a result of these rules. While the effects of these or other regulatory developments are difficult to predict, if broad market selling were to occur, it would likely lead to declines, possibly significant declines, in the price of the relevant commodity futures contracts and therefore, the level of the underlying and the return on and value of the securities.

You may have exposure to contracts that are not traded on regulated futures exchanges

The underlyings may include over-the-counter contracts (such as swaps and forward contracts) linked to commodities and traded on trading facilities that are subject to lesser degrees of regulation than futures contracts traded on regulated futures exchanges or, in some cases, no substantive regulation. As a result, trading in such contracts, and the manner in which prices and volumes are reported by the relevant trading facilities, may not be subject to the same provisions of, and the protections afforded by, the Commodity Exchange Act, as amended, or other applicable statutes and related regulations that govern trading on regulated futures exchanges. In addition, many electronic trading facilities have only recently initiated trading and do not have significant trading histories. The trading of contracts on such facilities and the inclusion of such contracts in the underlyings may expose you to greater risks than those presented by most exchange-traded futures contracts, including risks related to the liquidity and price histories of the relevant contracts.

Distortions or disruptions of market trading in futures contracts could adversely affect the value of and return on the securities

The commodity markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. These circumstances could adversely affect the settlement price of the futures contracts included in an underlying or futures contracts on an underlying itself and, therefore, the level of such underlying and the value of and return on the securities.

The level of an underlying may be calculated and published at different times than the prices of its components

The level of an underlying may not correspond to the prices of its components due to differences in timing. The prices of commodities, futures contracts or other components may be calculated and published at times when the level of the relevant underlying is not calculated and published. Consequently, there could be market developments or other events that cause or exacerbate the difference between the level of an underlying and the prices of its components.

An increase in the margin requirements for any futures contracts or an underlying or any futures contracts on commodities included in such underlying may adversely affect the value of the securities

Futures exchanges require market participants to post collateral in order to open and keep open positions in futures contracts. If an exchange increases the amount of collateral required to be posted to hold positions in a futures contract relating to any underlying or any components included in such underlying, market participants who are unwilling or unable to post additional collateral may return and liquidate their positions, which may cause the level of that futures contract to decline significantly. As a result, the value of the securities may be adversely affected.

Prices of futures contracts are characterized by high and unpredictable volatility, which could lead to high and unpredictable volatility in an underlying

Market prices of the futures contracts that may be included in an underlying or futures contracts on an underlying itself, could be highly volatile and may fluctuate rapidly based on numerous factors, including the factors that affect the prices of these futures contracts. The prices of futures contracts are subject to variables that may be less significant to the values of traditional securities, such as stocks and bonds. These variables may create additional risks that cause the value of the securities to be more volatile than the values of traditional securities. As a general matter, the risk of low liquidity or higher volatility around the maturity date of a futures contract is greater than in the case of other futures contracts because (among other factors) a number of market participants may be required to take physical delivery of the underlying commodities. Many commodities are also highly cyclical. The high volatility and cyclical nature of commodity markets may render such an investment inappropriate as the focus of an investment portfolio.

The securities may be linked to an underlying which tracks futures contracts, not physical commodities (or their spot prices). The price of a futures contract reflects the expected value of a commodity upon delivery in the future, whereas the spot price of a commodity reflects the immediate delivery value of the commodity. A variety of factors can lead to a disparity between the expected future price of a commodity and the spot price at a given point in time, such as the cost of storing the commodity for the term of the futures contract, interest charges incurred to finance the purchase of the commodity and expectations concerning supply and demand for the commodity. The price movements of a futures contract are typically correlated with the movements of the spot price of the referenced commodity, but the correlation is generally imperfect and price movements in the spot market may not be reflected in the futures market (and vice versa). Accordingly, the securities may underperform a similar investment that is linked to commodity spot prices.

The index sponsor may be required to replace a contract included in an underlying if the existing futures contract is terminated or replaced

The termination or replacement of a futures contract included in an underlying may be terminated or replaced by a futures exchange, in which case a comparable futures contract would be selected by the index sponsor, if available, to replace such futures contract. The termination or replacement of any designated futures contract may have an adverse impact on the return and value of the securities.

A commodity hedging disruption event may result in acceleration of the securities

If a commodity hedging disruption event (as defined under “Description of the Securities—Commodity Hedging Disruption Events”) occurs, we will have the right, but not the obligation, to accelerate the payment on the securities. The amount due and payable to you upon such early acceleration will be determined by the calculation agent in good faith in a commercially reasonable manner on the date on which we deliver notice of such acceleration and will be payable on the fifth business day following the day on which the calculation agent delivers notice of such acceleration. If a commodity hedging disruption event occurs and we decide to exercise our right to accelerate the payment on your securities, your investment may result in a loss and you may not be able to reinvest the proceeds in a comparable investment.

The relevant exchange (as defined under “Description of the Securities—Certain definitions”) is responsible for calculating the official settlement price or fixing level, as applicable, for the commodities included in any underlying(s). The relevant exchange may alter, discontinue or suspend calculation or dissemination of the official settlement price or fixing level for such commodities. Any of these actions could adversely affect the value of the securities. The relevant exchange has no obligation to consider your interests in calculating or revising the official settlement price or fixing level for such commodities.

We intend to use the proceeds from each offering (as indicated in the applicable pricing supplement) for our general corporate purposes, which may include the refinancing of our existing indebtedness outside Switzerland. We may also use some or all of the proceeds from any offering to hedge our obligations under the securities. In addition, we may also invest the proceeds temporarily in short-term securities. The net proceeds will be applied exclusively outside Switzerland unless Swiss fiscal laws allow such usage in Switzerland without triggering Swiss withholding taxes on payments of coupons on debt instruments.

One or more of our affiliates before and following the issuance of any securities may acquire or dispose of positions relating to any underlying or listed or over-the-counter options, futures contracts, forward contracts, swaps or options on the foregoing, or other derivatives or similar instruments linked or related to, any underlying to hedge our obligations under the securities. In the course of pursuing such a hedging strategy, the price at which such positions may be acquired or disposed of may affect the level of any underlying. Although we and our affiliates have no reason to believe that our or their hedging activities will have a material impact on the level of any underlying or the value of the securities, we cannot assure you that these activities will not have such an effect.

From time to time after issuance and prior to the maturity of the securities, depending on market conditions and other factors (including the level of any underlying), in connection with hedging certain of the risks associated with the securities, we expect that one or more of our affiliates will increase or decrease their initial hedging positions using dynamic hedging techniques and may take long or short positions in listed or over-the-counter options, futures contracts, forward contracts, swaps or options on the foregoing, or other derivative or similar instruments linked or related to, the underlyings. These other hedging activities may occur from time to time before the securities mature and will depend on market conditions and other factors (including the levels of the underlyings). In addition, we or one or more of our affiliates may take positions in other types of financial instruments that may become available in the future. To the extent that we, or one or more of our affiliates, have a hedge position in any commodities that compose any underlying(s) or in any instruments linked or related to any such commodities or underlying(s), we or one or more of our affiliates may liquidate a portion of those holdings at or about the time of the maturity or early redemption, if applicable, of any securities. Depending, among other things, on future market conditions, the aggregate amount and composition of such positions are likely to vary over time. Our or our affiliates’ hedging activities will not be limited to any particular exchange or market.

In addition, we or one or more of our affiliates may purchase, or otherwise acquire a long or short position in, the securities from time to time and may, in our or its sole discretion, hold, resell, exercise, cancel or retire such offered securities. We or one or more of our affiliates may also take hedging positions in other types of appropriate financial instruments that may become available in the future. To the extent that we or one or more of our affiliates have a hedge position in, or options, futures contracts, forward contracts, swaps or options on the foregoing, or other derivative or similar instruments linked or related to, any underlying, we or one or more of our affiliates may liquidate all or a portion of those holdings at or about the time of the maturity or early redemption of, or the payment of any interest or coupon(s) on, the securities. Depending, among other things, on future market conditions and other factors, the aggregate amount and the composition of such positions are likely to vary over time. Our or our affiliates’ hedging activities described in this section will not be limited to any particular exchange or market and may be influenced by a number of factors. It is possible that we or one or more of our affiliates may receive a profit from such hedging activities, even if the market value of the securities has declined. We are only able to determine profits or losses from any such hedging position when such position is closed out and any offsetting hedging position(s) are taken into account.

The original issue price of the securities will include the commissions paid to CSSU with respect to the securities and the cost of hedging our obligations under the securities. This cost of hedging includes the projected profit that our subsidiaries expect to realize in consideration for assuming the risks inherent in managing such hedging transactions. Since hedging our obligations entails risk and may be influenced by market forces beyond our or our subsidiaries’ control, such hedging may result in a profit that is more or less than initially projected, or could result in a loss.

We have no reason to believe that our hedging activities, as well as those of our affiliates, will have a material impact on the price of such options, futures contracts, forward contracts, swaps or options on the foregoing, or other derivative or similar instruments, or on the value of the securities or the underlyings. However, we cannot guarantee that our hedging activities, as well as those of our affiliates, will not affect such prices or values. We will use the remainder of the proceeds from the sale of the securities for the general corporate purposes described above.

This description of the terms of the securities adds information to the description of the general terms and provisions of debt securities in the accompanying prospectus supplement and prospectus. If this description differs in any way from the description in the prospectus supplement and prospectus, you should rely on this description. The applicable pricing supplement may also add, update or change the information contained in this product supplement or the other offering documents. If any information in the applicable pricing supplement is inconsistent with the other offering documents, you should rely on the information in that pricing supplement.

The securities are senior unsecured medium-term notes issued by Credit Suisse, acting through one of its branches, the return on which is linked to the positive or inverse performance of one or more underlyings or a basket, as specified in the applicable pricing supplement. We refer generally to each commodity index as an “underlying” and to each underlying included in a basket as a “basket component.” The one or more underlyings or the basket to which the securities will be linked will be specified in the applicable pricing supplement. If the securities are linked to the performance of any other reference asset, the terms applicable to such reference asset will be set forth in the applicable product supplement, pricing supplement or other supplement.

The securities will be issued under an indenture dated March 29, 2007, as may be amended or supplemented from time to time, between us and The Bank of New York Mellon, as trustee, and will rank pari passu with all of our other unsecured and unsubordinated obligations.

The securities are not deposit liabilities and are not insured or guaranteed by the FDIC or any other governmental agency of the United States, Switzerland or any other jurisdiction. Any payment on the securities is subject to our ability to pay our obligations as they become due.

The applicable pricing supplement will contain important terms relating to the determination of any payments on the securities. These may include: “buffer amount,” “buffer level,” “call return,” “contingent minimum return,” “coupon barrier level,” “coupon payment date(s),” “early redemption amount,” “early redemption date(s),” “early redemption notice date(s),” “downside leverage factor,” “final level,” “fixed payment percentage,” “initial level,” “knock-in level,” “lowest performing underlying,” “maximum return,” “observation date(s),” “observation period(s),” “security performance factor,” “strike date,” “threshold level,” “trigger observation date(s),” “trigger level,” “upside participation rate” and “underlying return.”

If your securities are linked to the performance of a basket, we may refer to the underlying return as the “basket return” and the initial level and the final level as the “initial basket level” and the “final basket level,” respectively.

The applicable pricing supplement will specify whether, and under what conditions, coupons will be paid on the securities, the applicable amount of any such coupons and/or rate per annum, as well as any other terms and conditions relating to the calculation, frequency and payment of such coupons.

For securities that pay coupons, each “coupon period” will be (i) the period beginning on, and including, the original issue date of the securities to, and excluding, the first scheduled coupon payment date, and each successive period beginning on, and including, a scheduled coupon payment date to, but excluding, the next scheduled coupon payment date, except the final coupon period, which will be from, and including, the preceding scheduled coupon payment date to, and excluding, the earlier of the scheduled maturity date or early redemption date, as the case may be, or (ii) the period specified in the applicable pricing supplement. The postponement of any coupon payment date will not shorten or lengthen any relevant coupon period.

The securities may be subject to an automatic redemption and/or may be redeemable prior to maturity at our option (the automatic redemption and redemption at our option, each, an “early redemption”), in each case in whole or in part, on such date(s) as specified in the applicable pricing supplement and upon such notice, if applicable, as may be specified in the applicable pricing supplement (such date(s), the “early redemption notice date(s)”).

If the securities are redeemed prior to the maturity date, you will receive only the principal amount of the securities or such other amount as specified in the applicable pricing supplement and any applicable coupons to, and including, the early redemption date. This payment will not be increased to include reimbursement for any discounts or commissions and hedging and other transactions costs, even upon early redemption. In this case, you will lose the opportunity to continue to accrue and be paid coupons, or to participate in the positive or inverse performance of any underlying or basket, from the early redemption date to the originally scheduled maturity date. The applicable pricing supplement will set forth the terms specific to any early redemption applicable to the securities.

The securities are not subject to redemption at the option of any security holder prior to maturity and are not subject to the defeasance provisions described in the accompanying prospectus under “Description of Debt Securities — Defeasance.”

The maturity date of the securities will be the date specified in the applicable pricing supplement, or the next succeeding business day if the scheduled maturity date is not a business day, unless the next business day falls in the next calendar month, in which case payment will be made on the first preceding business day. The maturity date is subject to postponement if the final valuation date is postponed for any reason, as described under “— Postponement of calculation dates” below.

No coupons or other payment will be payable because of any postponement of the maturity date.

The maturity date of the securities may be accelerated upon the occurrence of a commodity hedging disruption event, as described below in “—Commodity hedging disruption events.”

Unless previously accelerated, redeemed, or purchased by us and cancelled, the securities will be redeemed on the maturity date for an amount of cash determined as set forth in the applicable pricing supplement.

The following terms used in this product supplement have the following definitions:

The “basket component weightings” will be specified in the applicable pricing supplement and will be a percentage of a basket applicable to each basket component.

A “business day” is any day, other than a Saturday, Sunday or a day on which banking institutions in The City of New York, New York are generally authorized or obligated by law or executive order to close.

A “calculation date” is any trigger observation date, observation date, valuation date, trade date and strike date, if applicable, and any other day as specified in the applicable pricing supplement, subject to the provisions described under “— Postponement of calculation dates” below.

The “closing level” is, (i) with respect to a basket, on any trading day, the closing level of such basket calculated in accordance with the formula set forth in the applicable pricing supplement and (ii) with respect to an underlying, on any trading day for such underlying, the level of such underlying as determined by the calculation agent at the time at which the index sponsor of such underlying calculates the closing level to be published for such

underlying on such trading day, subject to the provisions described under “— Changes to the calculation of an underlying” below.

“Day count fraction” means, with respect to the calculation of any amount of interest on any security for any period of time, from, and including, the first day of such period to, but excluding, the last day of such period (a “calculation period”):

“D₂” is the calendar day (expressed as a number) immediately following the last day included in the calculation period, unless such number would be 31, in which case D₂ will be 30;

“Y₁” is the year (expressed as a number) in which the first day of the calculation period falls;

“Y₂” is the year (expressed as a number) in which the day immediately following the last day included in the calculation period falls;

“M₂” is the calendar month (expressed as a number) in which the day immediately following the last day included in the calculation period falls;

“D₁” is the first calendar day (expressed as a number) of the calculation period, unless (i) that day is the last day of February or (ii) such number would be 31, in which case D₁ will be 30; and

“D₂” is the calendar day (expressed as a number) immediately following the last day included in the calculation period, unless (i) that day is the last day of February but not the Maturity Date or (ii) such number would be 31, in which case D₂ will be 30.

“Index sponsor” means, with respect to an underlying, the sponsor of such underlying that will publish (or will have published on its behalf) a level for such underlying.

The “level” of (i) a basket, at any time during the term of the securities, is the level of such basket at such time calculated in accordance with the formula set forth in the applicable pricing supplement and subject to the provisions described under “— Changes to the calculation of an underlying” below, and (ii) any underlying, at any time during the term of the securities, is the level of such underlying published at such time by the index sponsor of such underlying and subject to the provisions described under “— Market Disruption Events” below.

An “observation date” will be the date(s) specified in the applicable pricing supplement or, for each underlying, the next succeeding trading day for such underlying if the scheduled observation date is not a trading day for such underlying, subject to the market disruption provisions described under “— Postponement of calculation dates” below.

“Related exchange” means, with respect to an underlying, each exchange or over-the-counter market on which futures or options contracts relating to such underlying are traded.

“Relevant exchange” means, with respect to an underlying, each organized exchange or market of trading for any component of such underlying (or any combination thereof).

The “trade date” will be the date set forth in the applicable pricing supplement.

“Trading day” means any day that is (or, but for the occurrence of a market disruption event with respect to an underlying, would have been) a day on which trading is generally conducted on the relevant exchange or the related exchanges for such underlying (each as defined herein).

A “trigger observation date” will be the date(s) specified in the applicable pricing supplement or, for each underlying, the next succeeding trading day for such underlying if the scheduled trigger observation date is not a trading day for such underlying, subject to the market disruption provisions described under “— Postponement of calculation dates” below.

The “valuation date” will be the date(s) specified in the applicable pricing supplement or, for each underlying, the next succeeding trading day for such underlying if the valuation date specified in the applicable pricing supplement is not a trading day for such underlying, subject to the market disruption provisions described under “— Postponement of calculation dates” below.

If the closing level or other relevant level(s) for any underlying is to be determined on any calculation date for the securities, but such date is not a trading day, then such level(s) for such underlying will be determined by the calculation agent on the immediately following trading day, unless a market disruption event has occurred or is continuing on any such trading day, in which case the provisions below will apply.

If the calculation agent determines that a market disruption event has occurred or is continuing with respect to any underlying on any calculation date for which a closing level must be determined, then such calculation date for such underlying will be postponed to the first succeeding trading day for such underlying on which the calculation agent determines that no market disruption event has occurred or is continuing with respect to such underlying, unless the calculation agent determines that a market disruption event has occurred or is continuing with respect to such underlying on each of the five trading days for such underlying immediately following such scheduled calculation date. In that case, (a) the fifth succeeding trading day for such underlying following such scheduled calculation date will be deemed to be the calculation date for such underlying, notwithstanding any market disruption event, and (b) the calculation agent will determine the closing level for such underlying on that deemed calculation date in accordance with the formula for, and method of calculating, such underlying last in effect prior to the commencement of the market disruption event with respect to such underlying, using exchange-traded prices on the relevant exchanges or, if trading in any index components included in such underlying has been materially suspended or materially limited, the calculation agent’s good faith estimate of the prices that would have prevailed on the relevant exchanges for such index components but for the suspension or limitation, as of the valuation time on that deemed calculation date, of each such index component (subject to the provisions described under”— Changes to the calculation of an underlying” below).

If two or more consecutive calculation dates are specified in the applicable pricing supplement and a market disruption event occurs or is continuing with respect to any underlying on any such calculation date (a “disrupted calculation date”) or any such disrupted calculation date is not a trading day for any underlying, then each calculation date for such underlying scheduled to occur on consecutive trading days following any such disrupted calculation date, if any, will be postponed by the corresponding number of trading days or scheduled trading days, as applicable, by which any such disrupted calculation date is postponed.

If the securities are linked to more than one underlying, the calculation date for any underlying that is not affected by a market disruption event will be the scheduled calculation date for such underlying.

Postponement of coupon payment dates, other relevant payment dates and the maturity date

If a coupon payment date is not a business day, the relevant coupon(s) will be payable on the first following business day, unless that business day falls in the next calendar month, in which case payment will be made on the first preceding business day. In addition, each coupon payment date is subject to postponement if the immediately preceding calculation date is not a trading day for any underlying or because a market disruption event with respect to any underlying has occurred or is continuing, as determined by the calculation agent, on such calculation date as described under “— Market Disruption Events” below. No coupon(s) or other payment will be payable hereon because of any such postponement of a coupon payment date.

If a calculation date (other than the final valuation date) is postponed with respect to any underlying as a result of a market disruption event, or because such calculation date is not a trading day for any underlying, to a date on or after the immediately following coupon payment date or other relevant payment date, then such coupon payment date or other relevant payment date will be postponed to the business day immediately following the latest date to which such calculation date is postponed for any underlying.

If the maturity date is not a business day, the relevant redemption amount and coupon(s) payable at maturity, if any, will be payable on the first following business day, unless that business day falls in the next calendar month, in which case payment will be made on the first preceding business day. If the final valuation date is postponed for any reason provided herein, then the maturity date will be postponed to the fifth business day following the final valuation date as postponed.

“Market disruption event” means, as determined by the calculation agent in its sole discretion:

which in each case, the calculation agent determines in its sole discretion has materially interfered with our ability or the ability of any of our affiliates to maintain, establish, adjust or unwind all or a material portion of any hedge with respect to the securities.

If an underlying (a) is not calculated and announced by its index sponsor, but is instead calculated and announced by a successor sponsor that is acceptable to the calculation agent or (b) is replaced by a successor index that uses what is, in the sole determination of the calculation agent, the same or a substantially similar formula for, and method of, calculation as used for such underlying, then such successor sponsor (if applicable) will be deemed to be the index sponsor for such underlying, and such successor index (if applicable) as so calculated and announced by its index sponsor will be deemed to supersede such underlying (such successor index, a “successor underlying”).

Upon any selection by the calculation agent of a successor underlying, such successor underlying will be substituted for the original underlying for all purposes relating to the securities, and we will, or will cause the calculation agent to, furnish notice thereof to us and the trustee.

If, (x) on or prior to a calculation date or other relevant date(s) on which a closing level for an underlying must be determined, the relevant index sponsor, index calculation agent or index creator makes, in the determination of the calculation agent, a material change in the formula for, or method of calculating, such underlying or in any other way materially modifies such underlying (other than a modification prescribed in such formula or method to maintain such underlying in the event of changes in constituent commodities or other routine events) or, (y) on any calculation date or other relevant date(s) on which a closing level for an underlying must be determined, the relevant index sponsor fails to calculate and announce a closing level for such underlying (including a permanent discontinuance of such underlying where there is no successor underlying as described above), then, in each case, the calculation agent will calculate the closing level of such underlying using the level of such underlying on such calculation date or relevant date(s) in accordance with the formula for, and method of calculating, the closing level for such underlying last in effect immediately prior to such change or failure, but using only those commodities included in such underlying that were also included in such underlying immediately prior to such change or failure. Notice of such an adjustment to an underlying will be provided to the trustee.

The calculation agent will be solely responsible for the determinations and calculations with respect to any event described below and its determinations and calculations will be conclusive absent manifest error.

If a commodity hedging disruption event (as defined below) occurs, we will have the right, but not the obligation, to accelerate the payment on the securities by providing, or causing the calculation agent to provide, written notice of our election to exercise such right to the trustee at its New York office, on which notice the trustee may conclusively rely, as promptly as possible and in no event later than the third business day immediately following the day on which such commodity hedging disruption event occurred. The amount due and payable upon such acceleration will be equal to the amount due on the securities at maturity or otherwise, calculated as though the relevant calculation date were the day on which notice of such commodity hedging disruption event occurred, as determined by the calculation agent in good faith in a commercially reasonable manner on the date such notice of acceleration is delivered and will be payable on the fifth business day thereafter. We will, or will cause the calculation agent to, provide written notice to the trustee at its New York office, on which notice the trustee may conclusively rely, and to the Depository Trust Company (“DTC”) of the cash amount due with respect to the securities as promptly as possible and in no event later than two business days prior to the date on which such payment is due. For the avoidance of doubt, the determination set forth above is only applicable to the amount due with respect to acceleration of the securities as a result of a commodity hedging disruption event.

(a) due to (i) the adoption of, or any change in, any applicable law, regulation or rule or (ii) the promulgation of, or any change in, the interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law, rule, regulation or order (including, without limitation, as implemented by the CFTC or any exchange or trading facility), in each case occurring on or after the trade date of the securities, the calculation agent

determines in good faith that it is contrary to such law, rule, regulation or order to purchase, sell, enter into, maintain, hold, acquire or dispose of our or our affiliates’ (A) positions or contracts in securities, options, futures, derivatives or foreign exchange or (B) other instruments or arrangements, in each case, in order to hedge individually or in the aggregate on a portfolio basis our obligations under the securities (“hedge positions”), including, without limitation, if such hedge positions are (or, but for the consequent disposal thereof, would otherwise be) in excess of any allowable position limit(s) in relation to any commodity traded on any exchange(s) or other trading facility (it being within the sole and absolute discretion of the calculation agent to determine which of the hedge positions are counted towards such limit); or

(b) for any reason, we or our affiliates are unable, after using commercially reasonable efforts, to (i) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) the calculation agent deems necessary to hedge the risk of entering into and performing our commodity-related obligations with respect to the securities, or (ii) realize, recover or remit the proceeds of any such transaction(s) or asset(s).

In case an event of default (as defined in the accompanying prospectus) with respect to any securities shall have occurred and be continuing, the amount declared due and payable upon any acceleration of the securities (in accordance with the acceleration provisions set forth in the accompanying prospectus) will be determined by the calculation agent and will equal, for each security, the arithmetic average, as determined by the calculation agent, of the fair market value of the securities (had the event of default not occurred) as determined by at least three, but not more than five, broker-dealers (which may include CSSU or any of our other subsidiaries or affiliates) as will make such fair market value determinations available to the calculation agent.

We may at any time purchase any securities, which may, in our sole discretion, be held, sold or cancelled.

Upon the purchase and surrender for cancellation of any securities by us or the redemption of any securities, such securities will be cancelled by the trustee.

We will issue the securities in the form of one or more fully-registered global securities, or the global notes, in denominations of $1,000 or integral multiples of $1,000 greater than $1,000 or such other denominations specified in the applicable pricing supplement. We will deposit the notes with, or on behalf of, The Depository Trust Company, New York, New York, or DTC, as the depositary, and will register the notes in the name of Cede & Co., DTC’s nominee. Your beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

As long as the securities are represented by the global notes, we will pay the redemption amount on the securities, if any, to or as directed by DTC as the registered holder of the global notes. Payments to DTC will be in immediately available funds by wire transfer. DTC will credit the relevant accounts of their participants on the applicable date.

For a further description of procedures regarding global securities representing book-entry securities, we refer you to “Description of Certain Provisions Relating to Debt Securities and Contingent Convertible Securities — Book-Entry System” in the accompanying prospectus and “Description of Notes — Book-Entry, Delivery and Form” in the accompanying prospectus supplement.

The calculation agent is Credit Suisse International, an affiliate of ours. The calculation agent makes all determinations with respect to the securities. All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will be conclusive for all purposes and binding upon all parties, including us and the beneficial owners of the securities, absent manifest error. The calculation agent will have no responsibility for good faith errors or omissions in its calculations and determinations, whether caused by negligence or otherwise.

The calculation agent will not act as your agent. Because the calculation agent is an affiliate of ours, potential conflicts of interest may exist between you and the calculation agent. Please refer to “Risk Factors — There may be conflicts of interest.”

Without notice to, or the consent of, the registered holder(s) of the securities, we may from time to time create and issue further securities ranking pari passu with the securities being offered hereby in all respects. Such further securities will be consolidated and form a single series with the securities being offered hereby and will have the same terms as to status, redemption or otherwise as the securities being offered hereby.

We may, without the consent of the registered holder(s) of the securities or the owners of any beneficial interest in the securities, amend the securities to conform their terms to the terms set forth in the applicable offering documents, and the trustee is authorized to enter into any such amendment without any such consent.

Credit Suisse may at any time substitute another of its branches for the branch through which it acts under the securities for all purposes under the securities.

The one or more underlyings or the basket to which the securities are linked will be specified in the applicable pricing supplement. If any underlying or basket component, as applicable, is replaced by a successor underlying or basket component, as applicable, as set forth above, such successor will be substituted for that underlying or basket component, for all purposes relating to the securities.

Additional information relating to the underlyings or the basket will be set forth in one or more underlying supplements or in the applicable pricing supplement.

We will provide historical information on any underlying(s) or the basket in the relevant pricing supplement. You should not misconstrue any historical levels or prices that we may provide in any pricing supplement as an indication of the future performance of any underlying(s) or the basket. Neither we nor any of our affiliates makes any representation to you regarding the future performance of any underlying(s) or the basket.

The following is a discussion of the material U.S. federal income and certain estate tax consequences of the ownership and disposition of the securities. It applies to you only if you purchase a security for cash in the initial offering at the “issue price,” which is the first price at which a substantial amount of the securities is sold to the public (not including sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), and hold it as a capital asset within the meaning of Section 1221 of the Code. Purchasers of securities at another time or price should consult their tax advisors regarding the U.S. federal tax consequences to them of the ownership and disposition of the securities. This discussion does not address all of the tax consequences that may be relevant to you in light of your particular circumstances or if you are a holder subject to special rules, such as:

If an entity that is classified as a partnership for U.S. federal income tax purposes holds the securities, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partnership holding the securities or a partner in such a partnership, you should consult your tax advisor as to the particular U.S. federal tax consequences of holding and disposing of the securities to you.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date of this product supplement, changes to any of which subsequent to the date of this product supplement may affect the tax consequences described herein, possibly with retroactive effect. This discussion does not address the effects of any applicable state, local or non-U.S. tax laws or the potential application of the Medicare contribution tax. You should consult your tax advisor about the application of the U.S. federal income and estate tax laws (including the possibility of alternative treatments of the securities) to your particular situation, as well as any tax consequences arising under the laws of any state, local or non-U.S. jurisdiction.

This discussion may be supplemented, modified or superseded by disclosure regarding U.S. federal tax consequences set out in an applicable pricing supplement, which you should read before making a decision to invest in the relevant securities.

There are no statutory, judicial or administrative authorities that directly address the U.S. federal tax treatment of certain securities described in this product supplement. In particular, the consequences of ownership and disposition of securities that are not treated as debt instruments for U.S. federal income tax purposes (“non-debt securities”) are subject to substantial uncertainty. For securities that are treated as debt instruments, there may be uncertainty regarding specific aspects of the timing and character of income you are required to recognize on the securities. We do not plan to request a ruling from the IRS, and the IRS or a court might not agree with the treatment and consequences described below.

Alternative U.S. federal income tax treatments of the securities are possible that, if applied, could materially and adversely affect the timing and character of income, gain or loss with respect to the securities. For example, the IRS could treat non-debt securities as debt instruments issued by us, with the consequences to U.S. Holders generally as described under “Tax Consequences to U.S. Holders—Securities Treated as Debt Instruments.” Under this treatment, as well as other potential alternative characterizations of the securities, you might be required to recognize taxable income at a time earlier than that described herein and/or recognize ordinary income or short-term capital gain rather than long-term capital gain.

For Non-U.S. Holders, an alternate treatment of a security could cause payments on the security to be subject to U.S. federal withholding tax as well as different information reporting requirements.

The U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. In addition, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect.

Moreover, if there is a change to the securities that results in the securities being treated as reissued for U.S. federal income tax purposes, as discussed below in "Possible Taxable Event," the treatment of the securities after such an event could differ from their prior treatment.

Except where stated otherwise, the following discussions of specific types of securities generally assume that the stated treatment of each type of security is respected and that no deemed retirement and reissuance of the securities has occurred. You should consult your tax advisor regarding the risk that an alternative U.S. federal income tax treatment applies to the securities.

This section applies only to U.S. Holders. You are a “U.S. Holder” if for U.S. federal income tax purposes you are a beneficial owner of a security that is:

The following discussion applies to securities treated as debt instruments for U.S. federal income tax purposes.

The discussion below applies generally to all securities treated as debt instruments, but is subject to special rules applicable to certain categories of debt instruments described below in “—Short-Term Securities,” “—Securities Treated as Variable Rate Debt Instruments” and “—Securities Treated as Contingent Payment Debt Instruments” and should be read in conjunction with those discussions, as applicable.

Payments of Interest. “Qualified stated interest” (as described below under “— Original Issue Discount”) on a security generally will be taxable to you as ordinary interest income at the time it accrues or is received in accordance with your method of accounting for U.S. federal income tax purposes.

Original Issue Discount. A security that has an “issue price” that is less than its “stated redemption price at maturity” will be considered to have been issued with original issue discount (“OID”) for U.S. federal income tax purposes (an “OID security”) unless the security satisfies a de minimis threshold under applicable Treasury regulations. Special rules governing the tax treatment of short-term securities and contingent payment debt instruments (which are not OID securities for purposes of this discussion) are described below under “— Short-Term Securities” and “— Securities Treated as Contingent Payment Debt Instruments,” respectively. The amount of OID will be equal to the excess of the stated redemption price at maturity over the issue price. The “stated redemption price at maturity” of a security generally will equal the sum of all payments required under the security other than payments of “qualified stated interest.” Qualified stated interest (“QSI”) generally includes stated interest unconditionally payable (other than in debt instruments of the issuer) at least annually at a single fixed rate, and also includes stated interest on certain floating-rate securities (as described under “—Securities Treated as Variable Rate Debt Instruments” below). If a security provides for more than one fixed rate of stated interest, interest payable at the lowest stated rate generally is QSI, with any excess included in the stated redemption price at maturity for purposes of determining whether the security was issued with OID.

If the difference between a security’s stated redemption price at maturity and its issue price is less than a de minimis amount as determined under applicable Treasury regulations, the security will not be treated as issued with OID and therefore will not be subject to the rules described below. If you hold securities with less than a de minimis amount of OID, (i) all stated interest on the securities will generally be treated as QSI and (ii) you generally will include any other discount in income, as capital gain, on a pro rata basis as principal payments are made on the security.

If you hold OID securities, you will be required to include any QSI in income when received or accrued, in accordance with your method of accounting for U.S. federal income tax purposes. In addition, you will be required to include OID in income as it accrues, in accordance with a constant-yield method based on a compounding of interest, regardless of your method of tax accounting.

Under this method, you will be required to include in ordinary income the sum of the “daily portions” of OID for all days during the taxable year that you own the OID security. The daily portions of OID are determined by allocating to each day in any accrual period a ratable portion of the OID on the OID security that is allocable to that period. Accrual periods may be any length and may vary in length over the term of an OID security, so long as no accrual period is longer than one year and each scheduled payment of principal or interest occurs on the first or last day of an accrual period. The amount of OID allocable to each accrual period is determined by (i) multiplying the “adjusted issue price” (as defined below) of the OID security at the beginning of the accrual period by a fraction, the numerator of which is the annual yield to maturity (defined below) of the OID security and the denominator of which is the number of accrual periods in a year and (ii) subtracting from that product the amount (if any) payable as QSI allocable to that accrual period. The “adjusted issue price” of an OID security at the beginning of any accrual period will generally be the sum of its issue price and the amount of OID allocable to all prior accrual periods, reduced by the amount of payments in all prior accrual periods other than QSI.

All payments on an OID security (other than QSI) will generally be viewed first as payments of previously accrued but unpaid OID and then as a payment of principal. The “annual yield to maturity” of an OID security is the discount rate (appropriately adjusted to reflect the length of accrual periods) that causes the present value on the issue date of all payments on the OID security to equal the issue price.

You may make an election to include in gross income all interest that accrues on any security (including QSI, OID and de minimis OID) in accordance with the constant-yield method based on the compounding of interest (a “constant-yield election”). This election may be revoked only with the consent of the IRS.

A security that is subject to early redemption may be governed by rules that differ from the general rules described above for purposes of determining its yield and maturity (which may affect whether the security is treated as issued with OID and, if so, the timing of accrual of the OID). Under applicable Treasury regulations, we will generally be presumed to exercise an option to redeem a security if the exercise of the option would lower the yield on the security. Conversely, you will generally be presumed to exercise an option to require us to repurchase a security if the exercise of the option would increase the yield on the security. If such an option were not in fact

exercised, the security would be treated, solely for purposes of calculating OID, as if it were redeemed and a new security were issued on the presumed exercise date for an amount equal to the security’s adjusted issue price on that date. If such a deemed reissuance occurs when the remaining term of the securities is one year or less, it is possible that the security would thereafter be treated as a short-term debt instrument. See “— Short-Term Securities” below

Amortizable Bond Premium. If you purchase a security (other than a contingent payment debt instrument, as described below under “—Securities Treated as Contingent Payment Debt Instruments”) for an amount that is greater than the sum of all amounts payable on the security after the purchase date, other than payments of QSI, you generally will be considered to have purchased the security with amortizable bond premium equal to such excess. If the security is not optionally redeemable prior to its maturity date, you generally may elect to amortize this premium over the remaining term of the security using a constant-yield method. If, however, the security may be optionally redeemed prior to maturity after you have acquired it, the amount of amortizable bond premium is generally determined by substituting the redemption date for the maturity date and the redemption price for the amount payable at maturity but only if the substitution results in a smaller amount of premium attributable to the period before the redemption date. You may generally use the amortizable bond premium allocable to an accrual period to offset QSI required to be included in your income with respect to the security in that accrual period. In addition, if you have purchased an OID security with amortizable bond premium, you will not be required to accrue any OID on such security. If you elect to amortize bond premium, you must reduce your tax basis in the security by the amount of the premium amortized in any year. An election to amortize bond premium applies to all taxable debt instruments then owned or thereafter acquired and may be revoked only with the consent of the IRS.

If you make a constant-yield election (as described under “— Original Issue Discount” above) for a security with amortizable bond premium, that election will result in a deemed election to amortize bond premium for all of your debt instruments with amortizable bond premium.

Sale or Other Taxable Disposition of a Security. Upon a sale or other taxable disposition of a security, you will recognize taxable gain or loss equal to the difference between the amount realized and your tax basis in the security. For this purpose, the amount realized does not include any amount attributable to accrued but unpaid QSI, which will be treated as a payment of interest and taxed as described under “— Payments of Interest” above. Your tax basis in a security will equal its cost, increased by the amounts of any OID you have previously accrued with respect to the security, if any, and decreased by any amortized premium and by the amount of any other payments on the security that do not constitute QSI.

Generally, gain or loss realized upon the sale or other taxable disposition of a security will be capital gain or loss and will be long-term capital gain or loss if you have held the security for more than one year. The deductibility of capital losses is subject to limitations.

The following discussion applies to securities with a term of one year or less (from but excluding the issue date to and including the last possible date that the securities could be outstanding pursuant to their terms) (“Short-Term Securities”). Generally, a Short-Term Security is treated as issued at a discount equal to the sum of all payments required on the security minus its issue price.

If you are a cash-method U.S. Holder, you generally will not be required to recognize income with respect to a Short-Term Security prior to maturity, other than with respect to the receipt of interest payments, if any, or pursuant to a sale or other taxable disposition of the security. If you are an accrual-method U.S. Holder (or a cash-method U.S. Holder who elects to accrue income on the security currently), you will be subject to rules that generally require accrual of discount on Short-Term Securities on a straight-line basis, unless you elect a constant-yield method of accrual based on daily compounding. In the case of Short-Term Securities that provide for one or more contingent payments, it is not clear whether or how any accrual should be determined prior to the relevant valuation date for such a payment. You should consult your tax advisor regarding the amount and timing of any accruals on such securities.

Upon a taxable disposition (including a sale, exchange, early redemption, or retirement) of a Short-Term Security, you will generally recognize gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and your tax basis in the security. Your tax basis in the security should equal the amount paid to acquire the security increased, if you accrue income on the security currently, by any previously accrued but unpaid discount. The amount of any resulting loss generally will be treated as a short-term capital loss, the deductibility of which is subject to limitations. The excess of the amount received at maturity over your tax basis in the security generally should be treated as ordinary income. If you sell a Short-Term Security providing for a contingent payment at maturity prior to the time the contingent payment has been fixed, it is not clear whether any gain you recognize should be treated as ordinary income, short-term capital gain, or a combination of ordinary income and short-term capital gain. You should consult your tax advisor regarding the treatment of a taxable disposition of Short-Term Securities providing for contingent payments.

If you are a cash-method U.S. Holder, unless you make the election to accrue income currently on a Short-Term Security, you will generally be required to defer deductions for interest paid on indebtedness incurred to purchase or carry the security in an amount not exceeding the accrued discount that you have not included in income. As discussed above, in the case of a Short-Term Security providing for a contingent payment, it is unclear whether or how accrual of discount should be determined prior to the relevant valuation date in respect of the payment. If you make the election to accrue income currently, that election will apply to all short-term debt instruments acquired by you on or after the first day of the first taxable year to which that election applies. You should consult your tax advisor regarding these rules.

The following discussion applies to floating-rate securities that are treated as variable rate debt instruments for U.S. federal income tax purposes (“VRDIs”).

Interest on VRDIs That Provide for a Single Variable Rate. Stated interest on a VRDI that provides for a single variable rate (a “Single Rate VRDI”) will be treated as QSI and will be taxable to you as ordinary interest income at the time it accrues or is received, in accordance with your method of tax accounting. If the stated principal amount of a Single Rate VRDI exceeds its issue price by at least a specified de minimis amount, this excess will be treated as OID that you must include in income as it accrues in accordance with a constant-yield method based on compounding of interest before the receipt of cash payments attributable to this income (as described above under “—General—Original Issue Discount”). If a VRDI provides for stated interest at a fixed rate for an initial period of one year or less followed by a variable rate where the variable rate on the issue date is intended to approximate the fixed rate (which will be presumed if the value of the variable rate on the issue date does not differ from the value of the fixed rate by more than 0.25%), the two rates will be treated for purposes of this and the next paragraph as a single variable rate.

Interest on VRDIs That Provide for Multiple Rates. This discussion refers to VRDIs that provide for (i) multiple variable rates or (ii) one or more variable rates and a single fixed rate as “Multiple Rate VRDIs.” Under applicable Treasury regulations, in order to determine the amount of QSI and OID in respect of Multiple Rate VRDIs, an equivalent fixed-rate debt instrument must be constructed. The equivalent fixed-rate debt instrument is constructed in the following manner: (i) first, if the Multiple Rate VRDI contains a fixed rate, that fixed rate is converted to a variable rate that preserves the fair market value of the security and (ii) second, each variable rate (including a variable rate determined under (i) above) is converted to a fixed rate substitute (which will generally be the value of that variable rate as of the issue date of the Multiple Rate VRDI) (the “equivalent fixed-rate debt instrument”). The rules discussed in “—General—Original Issue Discount” are then applied to the equivalent fixed-rate debt instrument to determine the amount, if any, of OID and the timing of accrual of any OID. You will be required to include the OID in income for federal income tax purposes as it accrues, in accordance with a constant-yield method based on a compounding of interest, as described above under “—General—Original Issue Discount.” QSI on a Multiple Rate VRDI will generally be taxable to you as ordinary interest income at the time it accrues or is received, in accordance with your method of tax accounting. If a Multiple Rate VRDI is not issued with OID, all stated interest on the Multiple Rate VRDI will be treated as QSI.

If the amount of interest you receive in a calendar year is greater than the interest assumed to be paid or accrued under the equivalent fixed-rate debt instrument, the excess is generally treated as additional QSI taxable to you as ordinary income. Otherwise, any difference will generally reduce the amount of QSI you are treated as receiving and will therefore reduce the amount of ordinary income you are required to take into income.

Sale or Other Taxable Disposition of a VRDI. Upon the sale or other taxable disposition of a VRDI, you generally will recognize capital gain or loss equal to the difference between the amount realized (other than amounts attributable to accrued but unpaid QSI, which will be treated as a payment of interest) and your tax basis in the VRDI. Your tax basis in a VRDI will equal the amount you paid to purchase the VRDI, increased by the amounts of OID (if any) you previously included in income with respect to the VRDI, and reduced by any payments other than QSI you received and any amortized premium. Your gain or loss generally will be long-term capital gain or loss if you held the VRDI for more than one year at the time of disposition.

The following discussion applies only to securities treated as contingent payment debt instruments for U.S. federal income tax purposes (“CPDIs”).

Interest Accruals on the CPDIs. We are required to determine a “comparable yield” for each issuance of CPDIs. The comparable yield is the yield at which we could issue a fixed-rate debt instrument with terms similar to those of the CPDIs, including the level of subordination, term, timing of payments and general market conditions, but excluding any adjustments for the riskiness of the contingencies or the liquidity of the CPDIs. Solely for purposes of determining the amount of interest income that you will be required to accrue, we are also required to construct a “projected payment schedule” in respect of the CPDIs representing a payment or a series of payments the amount and timing of which would produce a yield to maturity on the CPDIs equal to the comparable yield.

Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amounts that we will pay on the CPDIs.

For U.S. federal income tax purposes, you are required to use our determination of the comparable yield and projected payment schedule in determining interest accruals and adjustments in respect of the CPDIs, unless you timely disclose and justify the use of other estimates to the IRS. Regardless of your method of tax accounting for U.S. federal income tax purposes, you will be required to accrue, as interest income, OID on the CPDIs at the comparable yield, adjusted upward or downward to reflect the difference, if any, between the actual and the projected payments on the CPDIs during the year (as described below).

You will be required for U.S. federal income tax purposes to accrue an amount of OID, for each accrual period prior to and including the maturity (or earlier sale or other taxable disposition) of a CPDI, that equals the product of (i) the “adjusted issue price” of the CPDI (as defined below) as of the beginning of the accrual period, (ii) the comparable yield of the CPDI, adjusted for the length of the accrual period and (iii) the number of days during the accrual period that you held the CPDI divided by the number of days in the accrual period. The “adjusted issue price” of a CPDI is its issue price increased by any interest income you have previously accrued (determined without regard to adjustments due to differences between projected and actual payments) and decreased by the projected amounts of any payments previously made on the CPDI (without regard to actual amounts paid).

Adjustments to Interest Accruals on the CPDIs. In addition to interest accrued based upon the comparable yield as described above, you will be required to recognize interest income equal to the amount of any net positive adjustment (i.e., the excess of actual payments over projected payments) in respect of a CPDI for a taxable year. A net negative adjustment (i.e., the excess of projected payments over actual payments) in respect of a CPDI for a taxable year:

A net negative adjustment is not treated as a miscellaneous itemized deduction (for which deductions would be unavailable or, beginning in 2026, available only to a limited extent). Any net negative adjustment in excess of the amounts described above may be carried forward to offset future interest income in respect of the CPDI or to reduce the amount realized on a sale or other taxable disposition of the CPDI.

Sale or Other Taxable Disposition of the CPDIs. Upon a sale or other taxable disposition of a CPDI, you generally will recognize taxable income or loss equal to the difference between the amount received and your tax basis in the CPDI. Your tax basis in the CPDI will equal your purchase price for the CPDI increased by any interest income you have previously accrued (determined without regard to adjustments due to differences between projected and actual payments) and decreased by the projected amounts of any payments previously made on the CPDI (without regard to actual amounts paid). At maturity, you will be treated as receiving the projected amount for that date, and any difference between the amount actually received and that projected amount will be treated as a positive or negative adjustment governed by the rules described above under “—Adjustments to Interest Accruals on the CPDIs.” As described above, the amount you are treated as receiving upon a disposition of a CPDI, whether at or prior to maturity, will be reduced by any carryforward of a net negative adjustment. You generally must treat any income as interest income and any loss as ordinary loss to the extent of previous interest inclusions (reduced by the total amount of net negative adjustments previously taken into account as ordinary losses), and the balance as capital loss. These losses are not treated as miscellaneous itemized deductions. The deductibility of capital losses, however, is subject to limitations. Additionally, if you recognize a loss above certain thresholds, you may be required to file a disclosure statement with the IRS, as described below under “Reportable Transactions.” You should consult your tax advisor regarding this reporting obligation.

Special Rules for Contingent Payments that Fix Early. Special rules may apply if all the remaining payments on a CPDI become fixed substantially contemporaneously. For this purpose, payments will be treated as fixed if the remaining contingencies with respect to them are remote or incidental. Under these rules, you would be required to account for the difference between the originally projected payments and the fixed payments in a reasonable manner over the period to which the difference relates. In addition, you would be required to make adjustments to, among other things, your accrual periods and your tax basis in the CPDI. The character of any gain or loss on a sale or other taxable disposition of your CPDI also might be affected. If one or more (but not all) contingent payments on a CPDI became fixed more than six months prior to the relevant payment dates, you would be required to account for the difference between the originally projected payments and the fixed payments on a present value basis. You should consult your tax advisor regarding the application of these rules.

Securities Treated as Prepaid Financial Contracts that are Open Transactions

The following discussion applies to securities treated as prepaid financial contracts that are “open transactions” for U.S. federal income tax purposes.

A U.S. Holder should not be required to recognize income over the term of the securities prior to maturity, other than pursuant to an earlier taxable disposition of the securities.

However, if the payment at maturity becomes fixed (or subject to a fixed minimum amount at least equal to the issue price) prior to maturity, the consequences are not entirely clear. A security might be treated as terminated for U.S. federal income tax purposes at such time, in which case you might be required to recognize gain (if any) in respect of the security. In addition, the timing and character of income you recognize in respect of the security after that time could also be affected. You should consult your tax advisor regarding the treatment of the securities in such an event.

Upon a taxable disposition (including a sale, exchange, early redemption or retirement) of a security, you should recognize gain or loss equal to the difference between the amount realized and your tax basis in the security. Your tax basis in a security should generally equal the amount you paid to acquire it. Subject to the discussion below under “—Possible Higher Tax on Securities Linked to ‘Collectibles,’ ” this gain or loss should be long-term capital gain or loss if at the time of the taxable disposition you have held the security for more than one year, and short-term capital gain or loss otherwise. Long-term capital gains recognized by non-corporate U.S. Holders are generally subject to taxation at reduced rates. The deductibility of capital losses is subject to limitations.

Under current law, long-term capital gain recognized on a sale of “collectibles” (which includes, among others, metals) or an ownership interest in certain entities that hold collectibles is generally taxed at the maximum 28% rate applicable to collectibles. It is possible that long-term capital gain from a taxable disposition of certain securities linked to an underlying that is a collectible or is one of certain entities holding collectibles would be subject to the rate applicable to collectibles, instead of the lower long-term capital gain rate. Prospective investors should consult their tax advisors regarding an investment in a security linked to a collectible or to an entity holding collectibles.

The following discussion applies to securities treated for U.S. federal income tax purposes as prepaid financial contracts with one or more associated coupon payments.

The discussions under “—Securities Treated as Prepaid Financial Contracts that are Open Transactions,” other than “—Securities Treated as Prepaid Financial Contracts that are Open Transactions—Tax Treatment Prior to Disposition or Maturity” apply to the securities addressed in this section.

The U.S. federal tax treatment of coupon payments on the securities is unclear. The discussion herein generally assumes that the coupon payments on the securities are taxable as ordinary income to you at the time received or accrued in accordance with your regular method of accounting for U.S. federal income tax purposes. However, if a different treatment applied, the timing and character of income arising from the coupon payments could differ. A different treatment could also affect your tax basis in the securities, and therefore the amount of gain or loss you recognize on a disposition of the securities. Except where stated otherwise, the discussion herein assumes that the coupon payments are taxable as ordinary income at the time received or accrued in accordance with your regular method of tax accounting.

If the payment at maturity on a security becomes fixed (or subject to a fixed minimum amount at least equal to the issue price) prior to maturity, the consequences are not entirely clear. A security might be treated as terminated for U.S. federal income tax purposes at such time, in which case you might be required to recognize gain (if any) in respect of the security. In addition, the timing and character of income you recognize in respect of the security after that time could also be affected. You should consult your tax advisor regarding the treatment of the securities in such an event.

The following discussion applies to securities treated as a put option (the “Put Option”) written by you with respect to the underlying, secured by a deposit equal to the issue price of the security (the “Deposit”). This discussion generally assumes that the issue price of the security is equal to the amount due at maturity of the security (excluding the final coupon payment on the security) if the final value of the underlying equals or exceeds its initial value.

Subject to any discussion in the applicable pricing supplement, interest on the Deposits should generally be treated as ordinary interest income that is taxable to you at the time it accrues or is received in accordance with your method of tax accounting.

If the term of the securities is not more than a year, taking into account the latest possible date on which the securities could be repaid according to their terms, the special rules under “—Securities Treated as Debt Instruments—Short-Term Securities” should apply to interest on the Deposits.

The Put Premium should not be taken into account until retirement (which for purposes of this discussion includes an early redemption) or earlier sale or exchange of the security.

Upon a taxable disposition of a security prior to retirement, you should apportion the amount realized between the Deposit and the Put Option based on their respective values on the date of the disposition. If the value of the Put Option is negative, you should be treated as having made a payment of such negative value to the purchaser in exchange for the purchaser’s assumption of the Put Option, in which case a corresponding amount should be added to the amount realized in respect of the Deposit.

You should recognize gain or loss with respect to the Deposit in an amount equal to the difference between (i) the amount realized that is apportioned to the Deposit (other than any amount attributable to accrued interest on the Deposit, which should be treated as a payment of interest) and (ii) your basis in the Deposit (i.e., the price you paid to acquire the security). Such gain or loss should be long-term capital gain or loss if you have held the security for more than one year, and short-term capital gain or loss otherwise. See “—Securities Treated as Debt Instruments—Short-Term Securities” for special rules applicable to the Deposit if the term of the securities is no more than a year.

You should recognize gain or loss in respect of the Put Option in an amount equal to the total Put Premium you previously received, decreased by the amount deemed to be paid by you, or increased by the amount deemed to be paid to you, in exchange for the purchaser’s assumption of the Put Option. This gain or loss should be short-term capital gain or loss.

The coupon payment received upon retirement will be treated as described above under “Coupon Payments.”

If a security is retired for its stated principal amount (without taking into account any coupon payment), the Put Option should be deemed to have expired unexercised, in which case you should recognize short-term capital gain in an amount equal to the sum of all payments of Put Premium received, including the Put Premium received upon retirement.

At maturity, if you receive an amount of cash, not counting the final coupon payment, that is different from the stated principal amount, the Put Option should be deemed to have been exercised and you should be deemed to have applied the Deposit toward the cash settlement of the Put Option. In that case, you should recognize short-term capital gain or loss with respect to the Put Option in an amount equal to the difference between (i) the sum of the total Put Premium received (including the Put Premium received at maturity) and the cash you receive at maturity, excluding the final coupon payment, and (ii) the Deposit.

This section applies only to Non-U.S. Holders. You are a “Non-U.S. Holder” if for U.S. federal income tax purposes you are a beneficial owner of a security that is:

You are not a Non-U.S. Holder for purposes of this discussion if you are (i) an individual who is present in the United States for 183 days or more in the taxable year of disposition or (ii) a former citizen or resident of the United States and certain conditions apply. If you are or may become such a person during the period in which you hold a security, you should consult your tax advisor regarding the U.S. federal tax consequences of an investment in the securities.

As discussed below under “Possible Taxable Event,” under certain circumstances, the securities could be subject to a significant modification and therefore deemed to be terminated and reissued for U.S. federal income tax purposes. In that event, depending on the facts and the time of the deemed reissuance, the reissued securities might be treated in a manner different from their original treatment for U.S. federal income tax purposes. As a result, you might be subject to withholding tax in respect of the reissued securities, or might be required to provide certification of your status as a non-U.S. person in order to avoid being subject to withholding. You should consult your tax advisor regarding the consequences of a significant modification of the securities.

In the case of securities treated as debt for U.S. federal income tax purposes, you generally should not be subject to U.S. federal income or withholding tax on coupon payments on the securities, assuming you provide an appropriate IRS Form W-8 to the applicable withholding agent certifying under penalties of perjury that you are not a United States person.

In the case of securities other than those treated as debt for U.S. federal income tax purposes, we currently do not intend to treat coupon payments as subject to U.S. federal withholding tax, assuming you provide an appropriate IRS Form W-8 to the applicable withholding agent certifying under penalties of perjury that you are not a United States person. However, because of the uncertain treatment of the securities, it is possible that the IRS could assert that such payments are subject to U.S. withholding tax, or that we or another withholding agent may otherwise determine that withholding is required, in which case we or the other withholding agent may withhold at a rate of up to 30% on such payments.

If income on the securities is effectively connected with your conduct of a trade or business in the United States, see “—Effectively Connected Income” below.

Subject to the discussion below under “FATCA,” you generally should not be subject to U.S. federal withholding or income tax in respect of amounts you receive on a sale, exchange or retirement of a security (other than amounts received in respect of accrued interest, which will be treated as described above under “—Coupon Payments on the Securities”), provided that income in respect of the securities is not effectively connected with your conduct of a trade or business in the United States.

If you are engaged in a U.S. trade or business, and if income or gain from the securities are effectively connected with the conduct of that trade or business, you generally will be subject to regular U.S. federal income tax with respect to that income or gain in the same manner as if you were a U.S. Holder, subject to the provisions of an applicable income tax treaty. In this event, if you are a corporation, you should also consider the potential application of a 30% (or lower treaty rate) branch profits tax.

A change in the methodology by which an underlying is calculated, a change in the components of an underlying, the designation of a successor index or other similar circumstances resulting in a material change to an underlying or to the method by which amounts payable on the securities are calculated could result in a significant modification of the affected securities.

A significant modification would generally result in the securities being treated as terminated and reissued for U.S. federal income tax purposes. In that event, you might be required to recognize gain or loss (subject to the possible application of the wash sale rules) with respect to the securities, and your holding period for your securities could be affected. Moreover, depending on the facts at the time of the significant modification, the reissued securities could be characterized for U.S. federal income tax purposes in a manner different from their original treatment, which could have a significant and potentially adverse effect on the timing and character of income you recognize with respect to the securities after the significant modification.

You should consult your tax advisor regarding the consequences of a significant modification of the securities. Except where stated otherwise, the discussion herein assumes that there has not been a significant modification of the securities.

We may, without the consent of the holders of outstanding securities, issue additional securities with identical terms. Even if they are treated for non-tax purposes as part of the same series as the original securities, these additional securities may be treated as a separate issue for U.S. federal income tax purposes or otherwise be treated differently from the original securities.

In the case of securities treated as debt for U.S. federal income tax purposes, the additional securities may be considered to have been issued (in whole or in part) with OID even if the original securities had no OID, or the additional securities may have a greater amount of OID than the original securities. These differences may affect the market value of the original securities if the additional securities are not otherwise distinguishable from the original securities.

A security may be subject to U.S. federal estate tax if an individual Non-U.S. Holder, or an entity the property of which is potentially includible in such an individual’s gross estate for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), holds the security at the time of the individual’s death. The gross estate of a Non-U.S. Holder domiciled outside the United States includes only property deemed situated in the United States. Individual Non-U.S. Holders, and the entities mentioned above, should consult their tax advisors regarding the U.S. federal estate tax consequences of an investment in the securities in their particular situation.

A taxpayer that participates in a “reportable transaction” is subject to information reporting requirements under Section 6011 of the Code. Reportable transactions include, among other things, certain transactions identified by the IRS as well as certain losses recognized in an amount that exceeds a specified threshold level.

In 2015, the U.S. Treasury Department and the IRS released notices designating certain “basket options,” “basket contracts” and substantially similar transactions as reportable transactions. The notices apply to specified transactions in which a taxpayer or its “designee” has, and exercises, discretion to change the assets or an algorithm underlying the transaction. While an exercise of the type of discretion that would give rise to such reporting requirements in respect of the securities is not expected, if we, an index sponsor or calculation agent or other person were to exercise discretion under the terms of a security or an index underlying a security and were treated as a holder’s designee for these purposes, unless an exception applied certain holders of the relevant securities would be required to report certain information to the IRS, as set forth in the applicable Treasury regulations, or be subject to penalties. We might also be required to report information regarding the transaction to the IRS. You should consult your tax advisor regarding these rules.

Payments on the securities as well as the proceeds of a sale, exchange or other disposition (including retirement) of the securities may be subject to information reporting and, if you fail to provide certain identifying information (such as an accurate taxpayer identification number if you are a U.S. Holder) or meet certain other conditions, may also be subject to backup withholding at the rate specified in the Code. If you are a Non-U.S. Holder that provides an appropriate IRS Form W-8, you will generally establish an exemption from backup withholding. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the relevant information is timely furnished to the IRS.

Legislation commonly referred to as “FATCA” generally imposes a withholding tax of 30% on payments to certain non-U.S. entities (including financial intermediaries) with respect to certain financial instruments, unless various U.S. information reporting and due diligence requirements (that are in addition to, and potentially significantly more onerous than, the requirement to deliver an IRS Form W-8) have been satisfied. An intergovernmental agreement between the United States and the non-U.S. entity’s jurisdiction may modify these requirements. This legislation generally applies to interest from U.S. sources. While existing Treasury regulations would also require withholding on payments of gross proceeds of the disposition (including upon retirement) of securities that provide for U.S.-source interest, the U.S. Treasury Department has indicated in subsequent proposed regulations its intent to eliminate this requirement. The U.S. Treasury Department has stated that taxpayers may rely on these proposed regulations pending their finalization. If you are a Non-U.S. Holder, or a U.S. Holder holding securities through a non-U.S. intermediary, you should consult your tax advisor regarding the potential application of FATCA to the securities, including the availability of certain refunds or credits.

Notwithstanding anything to the contrary herein or in the applicable pricing supplement, we will not be required to pay any additional amounts with respect to amounts withheld in respect of U.S. federal income taxes.

The Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and Section 4975 of the Code, impose certain requirements on (a) employee benefit plans subject to Title I of ERISA, (b) individual retirement accounts, Keogh plans or other arrangements subject to Section 4975 of the Code, (c) entities whose underlying assets include “plan assets” (within the meaning of U.S. Department of Labor Regulation Section 2510.3–101, as modified by Section 3(42) of ERISA) by reason of investment by any such employee benefit plan, plan or arrangement therein (we refer to each entity enumerated in the foregoing paragraphs (a) – (c) as a “Plan”) and (d) persons who are fiduciaries with respect to Plans. In addition, certain governmental, church and non-U.S. plans (each, a “Non-ERISA Arrangement”) are not subject to Section 406 of ERISA or Section 4975 of the Code, but may be subject to other laws that are substantially similar to those provisions (each, a “Similar Law”).

In considering an investment in the securities with a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws. Fiduciaries of any Plans and Non-ERISA Arrangements should consult their own legal counsel before purchasing the securities.

In addition to ERISA’s general fiduciary standards, Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of a Plan and persons who have specified relationships to the Plan, i.e., “parties in interest” as defined in ERISA or “disqualified persons” as defined in Section 4975 of the Code (we refer to the foregoing collectively as “parties in interest”) unless exemptive relief is available by statute or under an exemption issued by the U.S. Department of Labor. Parties in interest that engage in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. We, and our current and future affiliates, including CSSU and the Calculation Agent, may be parties in interest with respect to many Plans. Thus, a Plan fiduciary considering an investment in the securities should also consider whether such an investment might constitute or give rise to a prohibited transaction under ERISA or Section 4975 of the Code. For example, the securities may be deemed to represent a direct or indirect sale of property, extension of credit or furnishing of services between us and an investing Plan which would be prohibited if we are a party in interest with respect to the Plan unless exemptive relief were available under an applicable exemption.

In this regard, each prospective purchaser that is, or is acting on behalf of, a Plan, and proposes to purchase the securities, should consider the exemptive relief available under the following prohibited transaction class exemptions, or PTCEs: (A) the in-house asset manager exemption (PTCE 96–23), (B) the insurance company general account exemption (PTCE 95–60), (C) the bank collective investment fund exemption (PTCE 91–38), (D) the insurance company pooled separate account exemption (PTCE 90–1) and (E) the qualified professional asset manager exemption (PTCE 84–14). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide a limited exemption for the purchase and sale of securities and related lending transactions, provided that neither the Issuer of the securities nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than adequate consideration (within the meaning of Section 408(b)(17) of ERISA or Section 4975(f)(10) of the Code) in connection with the transaction (the so-called “service provider exemption”). There can be no assurance that any of these statutory or class exemptions will be available with respect to transactions involving the securities.

Each purchaser or holder of the securities, and each fiduciary who causes any entity to purchase or hold the securities, shall be deemed to have represented and warranted, on each day such purchaser or holder holds such securities, that either (i) it is neither a Plan nor a Non-ERISA Arrangement and it is not purchasing or holding the securities on behalf of or with the assets of any Plan or Non-ERISA Arrangement, or (ii) its purchase, holding and subsequent disposition of such securities shall not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Code, or violate any provision of Similar Law.

In addition, any purchaser that is a Plan or Non-ERISA Arrangement or that is acquiring the securities on behalf of a Plan, including any fiduciary purchasing on behalf of a Plan or Non-ERISA Arrangement, shall be deemed to represent, in its corporate and its fiduciary capacity, by its purchase, holding, or disposition of the securities that (a) none of Credit Suisse, the Calculation Agent or any of their respective affiliates (collectively, the “Seller”) is a “fiduciary” (under Section 3(21) of ERISA, or under any regulation thereunder, or with respect to a Non-ERISA Arrangement under Similar Law) with respect to the acquisition, holding, or disposition of the securities, or as a result of any exercise by us or our affiliates of any rights in connection with the securities, (b) no communication from the Seller has been directed specifically to, or has been based on the particular investment needs of, such purchaser or has formed a primary basis for any investment decision by or on behalf of such purchaser, and (c) it recognizes and agrees that any communication from the Seller to the purchaser with respect to the securities is not intended by the Seller to be investment advice and is rendered in its capacity as a seller of such securities and not a fiduciary to such purchaser.

Each purchaser of a security will have exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the security does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any Similar Law. Nothing herein shall be construed as a representation that an investment in the securities would meet any or all of the relevant legal requirements with respect to investments by, or is appropriate for, Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

We will sell the securities to CSSU and certain other agents that are or may become party to the Distribution Agreement, as amended or supplemented, from time to time (CSSU and such other agents, each an “Agent” and collectively, the “Agents”), acting as principal, at the discounts or concessions set forth in the applicable pricing supplement, for resale to one or more investors or other purchasers at the offering prices specified in the applicable pricing supplement. Each Agent may offer the securities it has purchased as principal to other dealers. Each Agent may sell securities to any dealer at a discount and, unless otherwise specified in the applicable pricing supplement, the discount allowed to any dealer will not be in excess of the discount to be received by each Agent from us. After the initial public offering of any securities, the public offering price, concession and discount of such securities may be changed.

We may also sell securities to an Agent as principal for its own account at discounts to be agreed upon at the time of sale as disclosed in the relevant terms supplement. That Agent may resell securities to investors and other purchasers at a fixed offering price or at prevailing market prices, or prices related thereto at the time of resale or otherwise, as that Agent determines and as we will specify in the applicable pricing supplement. An Agent may offer the securities it has purchased as principal to other dealers. That Agent may sell the securities to any dealer at a discount and the discount allowed to any dealer will not be in excess of the discount that Agent will receive from us. After the initial public offering of securities that the Agent is to resell on a fixed public offering price basis, the Agent may change the public offering price, concession and discount.

Each issue of securities will be a new issue of securities with no established trading market. CSSU intends to make a secondary market in the securities. Any of our broker-dealer subsidiaries or affiliates, including CSSU, may use the offering documents in connection with the offers and sales of securities related to market making transactions by and through our broker-dealer subsidiaries or affiliates, including CSSU, at negotiated prices related to prevailing market prices at the time of sale or otherwise. Any of our broker-dealer subsidiaries or affiliates, including CSSU, may act as principal or agent in such transactions. None of our broker-dealer subsidiaries or affiliates, including CSSU, has any obligation to make a market in the securities and any broker-dealer subsidiary or affiliate that does make a market in the securities may discontinue any market making activities at any time without notice, at its sole discretion. No assurance can be given as to the liquidity of the trading market for the securities. The securities will not be listed on a national securities exchange in the United States or any other country.

We reserve the right to withdraw, cancel or modify the offer made hereby without notice.

Because CSSU is one of our wholly owned subsidiaries, CSSU has a “conflict of interest” within the meaning of FINRA Rule 5121 in any offering of the securities in which it participates. The net proceeds received from the sale of the securities will be used, in part, by CSSU or one of its affiliates in connection with hedging our obligations under the securities. The underwriting arrangements for any offering in which CSSU participates will comply with the requirements of FINRA Rule 5121 regarding a FINRA member firm’s distribution of the securities of an affiliate and related conflicts of interest. In accordance with FINRA Rule 5121, CSSU may not sell the securities to any of its discretionary accounts without the prior written approval of the customer.

We have agreed to indemnify CSSU against liabilities under the U.S. Securities Act of 1933, as amended, or contribute to payments that CSSU may be required to make in that respect. We have also agreed to reimburse CSSU for expenses.

In connection with the offering, CSSU may engage in stabilizing transactions and over-allotment transactions in accordance with Regulation M under the Exchange Act.

These stabilizing transactions may have the effect of raising or maintaining the market prices of the securities or preventing or retarding a decline in the market prices of the securities. As a result, the prices of the securities may be higher than the prices that might otherwise exist in the open market.

CSSU and its affiliates have engaged and may in the future engage in commercial banking and investment banking and other transactions with us and our affiliates in the ordinary course of business. Certain of the Agents engage in transactions with and perform services for us and our subsidiaries in the ordinary course of business.

In the United States, the securities may be offered for sale in those jurisdictions where it is lawful to make such offers.

Each Agent has represented and agreed that it will not offer or sell the securities in any non-U.S. jurisdiction (i) if that offer or sale would not be in compliance with any applicable law or regulation or (ii) if any consent, approval or permission is needed for that offer or sale by that Agent or for or on our behalf, unless the consent, approval or permission has been previously obtained. We will have no responsibility for, and the applicable Agent will obtain, any consent, approval or permission required by that Agent for the subscription, offer, sale or delivery by that Agent of the securities, or the distribution of any offering materials, under the laws and regulations in force in any non-U.S. jurisdiction to which that Agent is subject or in or from which that Agent makes any subscription, offer, sale or delivery. For additional information regarding selling restrictions, please see “Notice to Investors” in this product supplement.

No action has been or will be taken by us, CSSU or any dealer that would permit a public offering of the securities or possession or distribution of the offering documents in any jurisdiction other than the United States, where action for that purpose is required. No offers, sales or deliveries of the securities, or distribution of the offering documents relating to the securities may be made in or from any jurisdiction, except in circumstances that will result in compliance with any applicable laws and regulations and will not impose any obligations on us, CSSU, the Agents or any dealer.

Concurrently with the offering of the securities as described in this product supplement, we may issue other securities from time to time as described in the accompanying prospectus supplement and prospectus.

This document, and the documents related to the offering of the Securities, have not been submitted to the Argentine Securities Commission (“Comisión Nacional de Valores” or the “CNV” after its acronym in Spanish) for approval. Thus, the CNV has neither approved nor disapproved them, nor has the CNV passed upon or endorsed the merits of any offering or the accuracy or adequacy of such documents. Accordingly, the Securities may not be offered or sold to the public in Argentina, and, therefore, any transaction involving the Securities within Argentina must be done in a manner that does not constitute a public offering or a public distribution of the Securities under Argentine laws. This document does not constitute an offer to sell any of or an invitation to purchase, the Securities referred to therein to any prospective purchaser of the Securities in Argentina, nor do they constitute a solicitation of any prospective purchaser of the Securities in Argentina of an offer to buy or invitation to purchase any of the Securities referred to therein, under circumstances in which such offer, invitation or solicitation, as applicable, would be unlawful.

The securities have not been and will not be issued nor placed, distributed, offered or negotiated in the Brazilian capital markets. The issuance of the securities has not been nor will be registered with the Brazilian Securities Commission (Comissão de Valores Mobiliários) (“CVM”). Any public offering or distribution, as defined under Brazilian laws and regulations, of the securities in Brazil is not legal without prior registration under Law No. 6,385, of December 7, 1976, as amended, and Instruction No. 400, issued by the CVM on December 29, 2003, as amended. Documents relating to the offering of the securities, as well as information contained therein, may not be supplied to the public in Brazil (as the offering of the securities is not a public offering of securities in Brazil), nor be used in connection with any offer for subscription or sale of the securities to the public in Brazil. Therefore, each of the Agents has represented, warranted and agreed that it has not offered or sold, and will not offer or sell, the securities in Brazil, except in circumstances which do not constitute a public offering, placement, distribution or negotiation of securities in the Brazilian capital markets regulated by Brazilian legislation. Persons wishing to offer or acquire the securities within Brazil should consult with their own counsel as to the applicability of registration requirements or any exemption therefrom.

Neither the Issuer nor the notes have been registered with the Comisión para el Mercado Financiero (legal successor of the Superintendencia de Valores y Seguros) pursuant to Law No. 18,045,the Ley de Mercado de Valores, and regulations thereunder, so they may not be offered or sold publicly in Chile. This document does not constitute an offer of, or an invitation to subscribe for or purchase, the notes in the Republic of Chile, other than to individually identified investors pursuant to a private offering within the meaning of Article 4 of the Ley de Mercado de Valores (an offer that is not “addressed to the public at large or to a certain sector or specific group of the public”).
