Market Linked Securities—Auto-Callable with Contingent Coupon and Contingent Downside

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the EURO STOXX 50^® Index due March 29, 2023

n  Linked to the lowest performing of the S&P 500^® Index, the Russell 2000^® Index and the EURO STOXX 50^® Index (each referred to as an “Index” and collectively as the “Indices”)

n  Unlike ordinary debt securities, the securities do not provide for fixed payments of interest, do not repay a fixed amount of principal at stated maturity and are subject to potential automatic call prior to stated maturity upon the terms described below. Whether the securities pay a contingent coupon, whether the securities are automatically called prior to stated maturity and, if they are not automatically called, whether you are repaid the original offering price of your securities at stated maturity will depend in each case on the closing level of the lowest performing Index on the relevant calculation day. The lowest performing Index on any calculation day is the Index that has the lowest closing level on that calculation day as a percentage of its starting level 

n  Contingent Coupon. The securities will pay a contingent coupon on a quarterly basis until the earlier of stated maturity or automatic call if, and only if, the closing level of the lowest performing Index on the calculation day for that quarter is greater than or equal to its threshold level. However, if the closing level of the lowest performing Index on a calculation day is less than its threshold level, you will not receive any contingent coupon for the relevant quarter. If the closing level of the lowest performing Index is less than its threshold level on every calculation day, you will not receive any contingent coupons throughout the entire term of the securities. The contingent coupon rate will be determined on the pricing date and will be within the range of 8.00% to 9.00% per annum

n  Automatic Call. If the closing level of the lowest performing Index on any of the quarterly calculation days from September 2019 to December 2022, inclusive, is greater than or equal to its starting level, we will automatically call the securities for the original offering price plus a final contingent coupon

n  Potential Loss of Principal. If the securities are not automatically called prior to stated maturity, you will receive the original offering price at stated maturity if, and only if, the ending level of the lowest performing Index is greater than or equal to its threshold level. If the ending level of the lowest performing Index is less than its threshold level, you will lose more than 25%, and possibly all, of the original offering price of your securities

n  The threshold level for each Index is equal to 75% of its starting level

n  If the securities are not automatically called prior to stated maturity, you will have full downside exposure to the lowest performing Index from its starting level to its ending level if its ending level is less than its threshold level, but you will not participate in any appreciation of any Index and will not receive any dividends on securities included in any Index

n  Your return on the securities will depend solely on the performance of the Index that is the lowest performing Index on each calculation day. You will not benefit in any way from the performance of the better performing Indices. Therefore, you will be adversely affected if any Index performs poorly, even if the other Indices perform favorably

n  All payments on the securities are subject to the credit risk of Credit Suisse; if Credit Suisse defaults on its obligations, you could lose some or all of your investment

n  No exchange listing; you should be willing and able to hold your securities to stated maturity.

The securities have complex features and investing in the securities involves risks not associated with an investment in conventional debt securities. See “Selected Risk Considerations” beginning on page PRS-11 of this pricing supplement and “Risk Factors” beginning on page PS-3 of the accompanying product supplement.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the securities or passed upon the accuracy or the adequacy of this pricing supplement or the accompanying underlying supplement, the product supplement, the prospectus supplement and the prospectus.

Market Linked Securities—Auto-Callable with Contingent Coupon and Contingent Downside  

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the EURO STOXX 50^® Index due March 29, 2023

Investment Description

The Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the EURO STOXX 50^® Index due March 29, 2023 are senior unsecured debt securities of Credit Suisse that do not provide for fixed payments of interest, do not repay a fixed amount of principal at stated maturity and are subject to potential automatic call upon the terms described in this pricing supplement. Whether the securities pay a quarterly contingent coupon, whether the securities are automatically called prior to stated maturity and, if they are not automatically called, whether you are repaid the original offering price of your securities at stated maturity will depend in each case upon the closing level of the lowest performing of the S&P 500^® Index, the Russell 2000^® Index and the EURO STOXX 50^® Index (each referred to as an “Index,” and collectively as the “Indices”) on the relevant calculation day. The lowest performing Index on any calculation day is the Index that has the lowest closing level on that calculation day as a percentage of its starting level. The securities provide:

(i) quarterly contingent coupons at a rate of 8.00% to 9.00% per annum (to be determined on the pricing date) until the earlier of stated maturity or automatic call if, and only if, the closing level of the lowest performing Index on the applicable quarterly calculation day is greater than or equal to 75% of its starting level;

(ii) the possibility of an automatic early call of the securities for an amount equal to the original offering price plus a final contingent coupon if the closing level of the lowest performing Index on any of the quarterly calculation days from September 2019 to December 2022, inclusive, is greater than or equal to its starting level; and

(iii) if the securities are not automatically called prior to stated maturity:

(a) repayment of the original offering price if, and only if, the ending level of the lowest performing Index is greater than or equal to its threshold level; and

(b) full exposure to the decline in the level of the lowest performing Index from its starting level to its ending level if the ending level of the lowest performing Index is less than its threshold level.

If the closing level of the lowest performing Index on any quarterly calculation day is less than 75% of its starting level, you will not receive any contingent coupon for that quarter. If the securities are not automatically called prior to stated maturity and the ending level of the lowest performing Index is less than the threshold level, you will lose more than 25%, and possibly all, of the original offering price of your securities at stated maturity. Accordingly, you will not receive any protection if the ending level of the lowest performing Index is less than its threshold level.

Any return on the securities will be limited to the sum of your contingent coupons, if any. You will not participate in any appreciation of any Index, but you will be fully exposed to the decline in the level of the lowest performing Index from its starting level to its ending level if the securities are not automatically called prior to stated maturity and the ending level of the lowest performing Index is less than its threshold level.

All payments on the securities are subject to the credit risk of Credit Suisse.

Your return on the securities will depend solely on the performance of the Index that is the lowest performing Index on each calculation day. You will not benefit in any way from the performance of the better performing Indices. Therefore, you will be adversely affected if any Index performs poorly, even if the other Indices perform favorably.

The securities are riskier than alternative investments linked to only one of the Indices or linked to a basket composed of each Index. Unlike those alternative investments, the securities will be subject to the full risks of each Index, with no offsetting benefit from the better performing Indices. The securities are designed for investors who understand and are willing to bear this additional risk in exchange for the potential contingent coupons that the securities offer. Because the securities may be adversely affected by poor performance by any Index, you should not invest in the securities unless you understand and are willing to accept the full downside risks of each Index.

The S&P 500^® Index is an equity index that is intended to provide an indication of the pattern of common stock price movement in the large capitalization segment of the United States equity market. The Russell 2000^® Index is an equity index that is designed to reflect the performance of the small capitalization segment of the United States equity market. The EURO STOXX 50^® Index is an equity index that is composed of 50 component stocks of sector leaders in 11 Eurozone countries and is intended to provide an indication of the pattern of common stock price movement in the Eurozone.

Hypothetical Payout Profile

If the securities have not been previously automatically called, on each quarterly contingent coupon payment date, you will either receive a contingent coupon or you will not receive a contingent coupon, depending on the closing level of the lowest performing Index on the related quarterly calculation day.

Step 1: Determine which Index is the lowest performing Index on the relevant calculation day. The lowest performing Index on any calculation day is the Index with the lowest performance factor on that calculation day. The performance factor of an Index on a calculation day is its closing level on that calculation day as a percentage of its starting level (i.e., its closing level on that calculation day divided by its starting level).

Step 2: Determine whether a contingent coupon is paid on the applicable contingent coupon payment date based on the closing level of the lowest performing Index on the relevant calculation day, as follows:

On stated maturity, if the securities have not been automatically called prior to stated maturity, you will receive (in addition to the final contingent coupon, if any) a cash payment per security (the redemption amount) calculated as follows:

Step 1: Determine which Index is the lowest performing Index on the final calculation day. The lowest performing Index on the final calculation day is the Index with the lowest performance factor on the final calculation day. The performance factor of an Index on the final calculation day is its ending level as a percentage of its starting level (i.e., its ending level divided by its starting level).

Step 2: Calculate the redemption amount based on the ending level of the lowest performing Index, as follows:

Hypothetical Payout Profile (Continued)

The following profile illustrates the potential payment at stated maturity on the securities (excluding the final contingent coupon, if any) for a range of hypothetical performances of the lowest performing Index on the final calculation day from its starting level to its ending level, assuming the securities have not been automatically called prior to the stated maturity. This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual ending level of the lowest performing Index and whether you hold your securities to stated maturity. The performance of the better performing Indices is not relevant to your return on the securities.

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the EURO STOXX 50^® Index due March 29, 2023

Selected Risk Considerations

The securities have complex features and investing in the securities will involve risks not associated with an investment in conventional debt securities. You should carefully consider the risk factors set forth below as well as the other information contained in this pricing supplement and any accompanying product supplement, the prospectus supplement and prospectus, including the documents they incorporate by reference. An investment in the securities involves significant risks. Investing in the securities is not equivalent to investing directly in the Indices.

If The Securities Are Not Automatically Called Prior To Stated Maturity, You May Lose Some Or All Of The Original Offering Price Of Your Securities At Stated Maturity.

If the securities are not automatically called prior to stated maturity, you may receive less at stated maturity than you originally invested in the securities, or you may receive nothing, excluding contingent coupons, if any. If the ending level of the lowest performing Index is less than its threshold level, you will be fully exposed to any depreciation in the lowest performing Index. In this case, the payment at stated maturity you will be entitled to receive will be less than the original offering price of your securities, and you could lose your entire investment. It is not possible to predict whether the ending level of the lowest performing Index will be less than its threshold level and, in such case, by how much the level of the lowest performing Index has decreased from its starting level to its ending level. Any payment on the securities is subject to our ability to pay our obligations as they become due.

Regardless Of The Amount Of Any Payment You Receive On The Securities, Your Actual Yield May Be Different In Real Value Terms.

Inflation may cause the real value of any payment you receive on the securities to be less at stated maturity than it is at the time you invest. An investment in the securities also represents a forgone opportunity to invest in an alternative asset that generates a higher real return. 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 Securities Do Not Provide For Regular Fixed Interest Payments.

Unlike conventional debt securities, the securities do not provide for regular fixed interest payments. The number of contingent coupons you receive over the term of the securities, if any, will depend on the performance of the Indices during the term of the securities. On each quarterly contingent coupon payment date you will receive a contingent coupon if, and only if, the closing level of the lowest performing Index on the immediately preceding calculation day is greater than or equal to its threshold level. If the closing level of the lowest performing Index on any calculation day is less than its threshold level, you will not receive any contingent coupon on the related contingent coupon payment date, and if the closing level of the lowest performing Index is less than its threshold level on each calculation day over the term of the securities, you will not receive any contingent coupons during the term of the securities. Thus, the securities are not a suitable investment for investors who require regular fixed income payments, since the number of contingent coupons is variable and may be zero.

In addition, if interest rates generally increase over the term of the securities, it is more likely that the contingent 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, 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 initial investment. Even if you do receive some or all of your initial investment at stated maturity, you will not be compensated for the time value of money. These securities are not short-term investments, so you should carefully consider these risks before investing.

The Securities Are Subject To The Full Risks Of Each Index And Will Be Negatively Affected If Any Index Performs Poorly, Even If The Other Indices Perform Favorably.

You are subject to the full risks of each Index. If any Index performs poorly, you will be negatively affected, even if the other Indices perform favorably. The securities are not linked to a basket composed of the Indices, where the better performance of some Indices could offset the poor performance of others. Instead, you are subject to the full risks of whichever Index is the lowest performing Index on each calculation day. For example, if one Index appreciates from its starting level to its ending level, but the ending level of the lowest performing Index is less than its threshold level, you will be exposed to the depreciation of the lowest performing Index and you will not benefit from the performance of any other Index. As a result, the securities are riskier than an alternative investment linked to only one of the Indices or linked to a basket composed of each Index. Each additional Index to which the securities are linked increases the risk that the securities will perform poorly. You should not invest in the securities unless you understand and are willing to accept the full downside risks of each Index.

It is impossible to predict the relationship between the Indices. If the performances of the Indices exhibit no correlation to each other, it is more likely that one of the Indices will cause the securities to perform poorly. However, if the performances of the equity securities included in each Index are related such that the performances of the Indices are correlated, then there is less likelihood that only one Index will cause the securities to perform poorly. Furthermore, to the extent that each Index represents a different market

Selected Risk Considerations (Continued)

segment or market sector, the risk of one Index performing poorly is greater. As a result, you are not only taking market risk on each Index, you are also taking a risk relating to the relationship among the Indices.

Your Return On The Securities Will Depend Solely On The Performance Of The Index That Is The Lowest Performing Index On Each Calculation Day, And You Will Not Benefit In Any Way From The Performance Of The Better Performing Indices.

Your return on the securities will depend solely on the performance of the Index that is the lowest performing Index on each calculation day. Although it is necessary for each Index to close above its respective threshold level on the relevant calculation day in order for you to receive a quarterly contingent coupon and for you to be repaid the original offering price of your securities at stated maturity, you will not benefit in any way from the performance of the better performing Indices. The securities may underperform an alternative investment linked to a basket composed of the Indices, since in such case the performance of the better performing Indices would be blended with the performance of the lowest performing Index, resulting in a better return than the return of the lowest performing Index alone.

The Starting Level of Any Index May Be Determined On A Date Later Than The Pricing Date.

The starting level of any Index may be determined after the pricing date. In the event that the closing level for any Index is not available on the pricing date, the starting level for such Index will be determined on the immediately following trading day on which a closing level is available. Under these circumstances, you will not know the starting level of such Index until a date later than the pricing date.

More Favorable Terms Are Generally Associated With Greater Expected Volatility, And Can Indicate A Greater Risk Of Loss.

“Volatility” refers to the frequency and magnitude of changes in the level of an Index. The greater the expected volatility with respect to an Index on the pricing date, the higher the expectation as of the pricing date that the closing level of such Index could be less than its threshold level on any calculation day, indicating a higher expected risk of loss on the securities. This greater expected risk will generally be reflected in a higher contingent coupon rate than the yield payable on our conventional debt securities with a similar stated maturity, or in more favorable terms (such as lower threshold levels) than for similar securities linked to the performance of an index with a lower expected volatility as of the pricing date. You should therefore understand that a relatively higher contingent coupon rate may indicate an increased risk of loss. Further, relatively lower threshold levels may not necessarily indicate that you will receive a contingent coupon on any contingent coupon payment date or that the securities have a greater likelihood of a return of principal at stated maturity. The volatility of any Index can change significantly over the term of the securities. The levels of the Indices for your securities could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Indices and the potential to lose a significant portion, and possibly all, of the original offering price per security at stated maturity.

At Stated Maturity Or Upon Automatic Call, The Securities Will Not Pay More Than The Original Offering Price Of Your Securities, Plus The Final Contingent Coupon, If Any.

At stated maturity or upon automatic call, the securities will not pay more than the original offering price of your securities, plus the final contingent coupon, if any, regardless of the performance of any Index. Even if the ending level of each Index is greater than its respective starting level, you will not participate in the appreciation of any Index. The maximum amount payable with respect to the securities (excluding contingent coupons, if any) is $1,000 for each $1,000 original offering price.

The Securities Are Subject To A Potential Automatic Call, Which Would Limit Your Opportunity To Be Paid Contingent Coupons Over The Full Term Of The Securities.

The securities are subject to a potential automatic call. If the closing level of the lowest performing Index on any of the quarterly calculation days is greater than or equal to its starting level, the securities will be automatically called and you will be entitled to receive a cash payment equal to the original offering price of the securities you hold and the contingent coupon payable on that contingent coupon payment date, and no further payments will be made in respect of the securities. In this case, you will lose the opportunity to continue to be paid contingent coupons from the call settlement date to the scheduled stated maturity.

The Securities Are Subject To A Potential Automatic Call, Which Exposes You To Reinvestment Risk.

The securities are subject to a potential automatic call. If the securities are automatically called prior to the stated maturity, 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.

Selected Risk Considerations (Continued)

Historical Performance Of Any Index Is Not Indicative Of Future Performance.

The future performance of any Index cannot be predicted based on its historical performance. We cannot guarantee that the closing level or ending level of any Index will be at a level that would result in a positive return on your overall investment in the securities.

We And Our Affiliates Generally Do Not Have Any Affiliation With Any Index Or Index Sponsor And Are Not Responsible For Its Public Disclosure of Information.

We and our affiliates generally are not affiliated with any Index or index sponsor in any way (except for licensing arrangements) and have no ability to control or predict its actions, including any errors in or discontinuance of disclosure regarding its methods or policies.

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

Changes To Any Index Could Adversely Affect The Securities.

The index sponsor can add, delete or substitute the components included in any Index, make other methodological changes that could change the level of any Index, or discontinue or suspend calculation or dissemination of any Index at any time. If one or more of these events occurs, the calculation of the redemption amount payable at stated maturity will be adjusted to reflect such event or events. Please refer to “Additional Terms of the Securities—Adjustments to an Index” and “Additional Terms of the Securities—Discontinuance of an Index” herein. Any of these actions could adversely affect the amount payable in respect of the securities and/or the value of the securities.

We Cannot Control The Actions Of Any Issuers Whose Equity Securities Are Included In Or Held By Any Index.

We cannot control the actions of any issuers of the equity securities included in or held by any Index. Actions by such issuers may have an adverse effect on the level of an Index and, consequently, on the value of the securities.

The Securities Are Linked To The Russell 2000^® Index And Are Subject To The Risks Associated With Small-Capitalization Companies.

The Russell 2000^® Index is composed of equity securities issued by companies with relatively small market capitalization. These equity securities often have greater stock price volatility, lower trading volume and less liquidity than the equity securities of large-capitalization companies, and are more vulnerable to adverse business and economic developments than those of large-capitalization companies. In addition, small-capitalization companies are typically less established and less stable financially than large-capitalization companies. These companies may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products. Therefore, the Russell 2000^® Index may be more volatile than it would be if it were composed of equity securities issued by large-capitalization companies.

The Closing Level Of The EURO STOXX 50^® Index Will Not Be Adjusted For Changes In Exchange Rates Relative To The U.S. Dollar Even Though The Equity Securities Included In The EURO STOXX 50^® Index Are Traded In A Foreign Currency And The Securities Are Denominated In U.S. Dollars.

The value of your securities will not be adjusted for exchange rate fluctuations between the U.S. dollar and the currencies in which the equity securities included in the EURO STOXX 50^® Index are based. Therefore, if the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the securities, you will not receive any additional payment or incur any reduction in your return, if any, at stated maturity.

Foreign Securities Markets Risk.

Some or all of the assets included in the EURO STOXX 50^® Index are issued by foreign companies and trade in foreign securities markets. Investments in the securities therefore involve risks associated with the securities markets in those countries, including risks of volatility in those markets, government intervention in those markets and cross shareholdings in companies in certain countries. Also, foreign companies are generally subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies. The equity securities included in the EURO STOXX 50^® Index may be more volatile than domestic equity securities and may be subject to different political, market, economic, exchange rate, regulatory and other risks, including changes in foreign governments, economic and fiscal policies, currency exchange laws or other laws or restrictions. Moreover, the economies of foreign countries may differ favorably or unfavorably from the economy of the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources

and self-sufficiency. These factors may adversely affect the values of the equity securities included in the EURO STOXX 50^® Index, and therefore the performance of the EURO STOXX 50^® Index and the value of the securities.

The Securities Are Subject To The Credit Risk Of Credit Suisse.

Investors are dependent on our ability to pay all amounts due on the securities and, 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 stated maturity.

Hedging And Trading Activity Could Adversely Affect Our Payment To You At Stated Maturity.

Credit Suisse (or any of its affiliates) or WFS (or any of its affiliates) may carry out hedging activities related to the securities, including in instruments related to the Indices. Credit Suisse (or any of its affiliates) or WFS (or any of its affiliates) may also trade instruments related to the Indices from time to time. Any of these hedging or trading activities on or prior to the pricing date and during the term of the securities could adversely affect our payment to you at stated maturity.

The Estimated Value Of The Securities On The Pricing Date May Be Less Than The Original Offering Price.

The initial estimated value of your securities on the pricing date (as determined by reference to our pricing models and our internal funding rate) may be significantly less than the original offering price. The original offering price of the securities includes any 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 pricing 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 mid-market pricing. 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 time to stated 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 estimated values of similar securities of other issuers.

Effect Of Interest Rate Used In Structuring The Securities.

The internal funding rate we use in structuring securities 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 pricing 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 “The Estimated Value Of The Securities Is Not An Indication Of The Price, If Any, At Which Credit Suisse Or Any Other Person May Be Willing To Buy The Securities From You In The Secondary Market” below.

The Estimated Value Of The Securities Is Not An Indication Of The Price, If Any, At Which Credit Suisse Or Any Other Person May Be Willing To Buy The Securities From You In The Secondary Market.

If Credit Suisse (or any of its affiliates) or WFS (or any of its affiliates) bid for your securities in secondary market transactions, the secondary market price (and the value used for account statements or otherwise) may be higher or lower than the original offering price and the estimated value of the securities on the pricing date. Neither Credit Suisse (or any of its affiliates) nor WFS (or any of its affiliates) is obligated to make a secondary market. The estimated value of the securities on the cover of this pricing supplement does not represent a minimum price at which Credit Suisse or WFS 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. These other factors include our internal funding rate, customary bid and ask spreads and other transaction costs, changes in market conditions and any deterioration or improvement in our creditworthiness. In circumstances where our internal funding rate is lower than our secondary market credit spreads, our secondary market bid for your securities could be more favorable than what other dealers might bid because, assuming all else equal, we use the

lower internal funding rate to price the securities and other dealers might use the higher secondary market credit spread to price them. Furthermore, assuming no change in market conditions from the pricing date, the secondary market price of your securities will be lower than the original offering price because it will not include any 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.

Credit Suisse (or any of its affiliates) or WFS (or any of its affiliates) 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 that were included in the original offering price, and that higher price may also be initially used for account statements or otherwise. Credit Suisse (or any of its affiliates) or WFS (or any of its affiliates) 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 approximately three months.

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

A Contingent Coupon Payment Date, A Call Settlement Date And The Stated Maturity May Be Postponed If A Calculation Day Is Postponed.

If a postponement occurs with respect to a calculation day other than the final calculation day for any Index, then the related contingent coupon payment date or call settlement date, as applicable, will be postponed. If a postponement occurs with respect to the final calculation day for any Index, the stated maturity will be the later of (i) the initial stated maturity and (ii) three business days after the last final calculation day as postponed. For additional information, see “Additional Terms of the Securities—Market Disruption Events” and “Terms of the Securities—Postponement of a Calculation Day” herein.

Postponement Of Certain Dates May Adversely Affect Your Return.

If the calculation agent determines that a market disruption event has occurred or that any calculation day is not a trading day, it is possible that one or more calculation days and stated maturity will be postponed, and your return could be adversely affected. No coupon payments or other payment will be payable as a result of such postponement. For additional information, see “Additional Terms of the Securities—Market Disruption Events” and “Terms of the Securities—Postponement of a Calculation Day” herein.

Credit Suisse Is Subject To Swiss Regulation.

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.

The Securities Will Not Be Listed On Any Securities Exchange And A Trading Market For The Securities May Not Develop.

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 stated maturity, you may not be able to do so or you may have to sell them at a substantial loss.

Our Economic Interests Are Potentially Adverse To Your Interests.

We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent 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 are potentially adverse to your interests as an investor in the securities. Further, hedging activities may adversely affect any payment on or the value of the securities. Any profit in connection with such hedging activities will be in addition to any other compensation that we and our affiliates receive for the sale of the securities, which creates an additional incentive to sell the securities to you.

Selected Risk Considerations (Continued)

Unpredictable Economic And Market Factors Will Affect The Value Of The Securities.

The payout on the securities can be replicated using a combination of the components described in “The Estimated Value Of The Securities On The Pricing Date May Be Less Than The Original Offering Price.” Therefore, in addition to the levels of any Index, the terms of the securities at issuance and the value of the securities prior to stated maturity may be influenced by factors that impact the value of fixed income securities and options in general such as:

o the expected and actual volatility of the Indices;

o the expected and actual correlation, if any, between the Indices;

o the time to stated maturity of the securities;

o the dividend rate on the equity securities included in the Indices;

o interest and yield rates in the market generally;

o investors’ expectations with respect to the rate of inflation;

o geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the components included in the Indices or markets generally and which may affect the levels of the Indices; and

o our creditworthiness, including actual or anticipated downgrades in our credit ratings.

Some or all of these factors may influence the price that you will receive if you choose to sell your securities prior to stated maturity. The impact of any of the factors set forth above may enhance or offset some or all of any change resulting from another factor or factors.

No Ownership Rights Relating To The Indices.

Your return on the securities will not reflect the return you would realize if you actually owned the assets that comprise the Indices. The return on your investment is not the same as the total return you would receive based on the purchase of the equity securities that comprise the Indices.

No Dividend Payments Or Voting Rights.

As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to the equity securities that comprise the Indices.

The U.S. Federal Tax Consequences Of An Investment In The Securities Are Unclear.

There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the securities are uncertain, and the IRS or a court might not agree with the treatment of the securities as described in “United States Federal Tax Considerations” below. If the IRS were successful in asserting an alternative treatment, the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized by U.S. investors and the withholding tax consequences to non-U.S. investors, might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the securities, possibly retroactively.

We intend to use the proceeds of this offering for our general corporate purposes, which may include the refinancing of existing debt outside Switzerland.

Such hedging or trading activities on or prior to the pricing date and during the term of the securities (including on any calculation day) could adversely affect the levels of the Indices and, as a result, could decrease the amount you may receive on the securities at stated maturity.

Hypothetical Returns

If the securities are automatically called:

If the securities are automatically called prior to stated maturity, you will receive the original offering price of your securities plus a final contingent coupon on the call settlement date. In the event the securities are automatically called, your total return on the securities will equal any contingent coupons received prior to the call settlement date and the contingent coupon received on the call settlement date.

If the securities are not automatically called:

If the securities are not automatically called prior to stated maturity, the following table illustrates, for a range of hypothetical performance factors of the lowest performing Index on the final calculation day, the hypothetical redemption amount payable at stated maturity per security (excluding the final contingent coupon, if any). The performance factor of the lowest performing Index on the final calculation day is its ending level expressed as a percentage of its starting level (i.e., its ending level divided by its starting level).

Hypothetical performance factor of lowest performing Index on final calculation day	Hypothetical payment at stated maturity per security

The above figures do not take into account contingent coupons, if any, received during the term of the securities. As evidenced above, in no event will you have a positive rate of return based solely on the redemption amount received at stated maturity; any positive return will be based solely on the contingent coupons, if any, received during the term of the securities.

The above figures are for purposes of illustration only and may have been rounded for ease of analysis. If the securities are not automatically called prior to stated maturity, the actual amount you will receive at stated maturity will depend on the actual ending level of the lowest performing Index. The performance of the better performing Indices is not relevant to your return on the securities.

Hypothetical Contingent Coupons

Set forth below are three examples that illustrate how to determine whether a contingent coupon will be paid and whether the securities will be automatically called on a quarterly contingent coupon payment date prior to stated maturity. The examples do not reflect any specific quarterly contingent coupon payment date. The following examples reflect a hypothetical contingent coupon rate of 8.00% per annum (the bottom of the specified range for the contingent coupon rate) and assume the hypothetical starting level, threshold level and closing levels for each Index indicated in the examples. The actual contingent coupon rate will be determined on the pricing date. The terms used for purposes of these hypothetical examples do not represent any actual starting level or threshold level. The hypothetical starting level of 100 for each Index has been chosen for illustrative purposes only and does not represent the actual starting level for any Index. The actual starting level and threshold level for each Index will be determined on the pricing date and will be set forth under “Terms of the Securities” above. For historical data regarding the actual closing levels of the Indices, see the historical information set forth herein. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis.

Example 1. The closing level of the lowest performing Index on the relevant calculation day is greater than or equal to its threshold level and less than its starting level. As a result, investors receive a contingent coupon on the applicable quarterly contingent coupon payment date and the securities are not automatically called.

	S&P 500® Index	Russell 2000® Index	EURO STOXX 50® Index
Hypothetical starting level:	100	100	100
Hypothetical closing level on relevant calculation day:	90	95	80
Hypothetical threshold level:	75	75	75
Performance factor (closing level on calculation day divided by starting level):	90%	95%	80%

Step 1: Determine which Index is the lowest performing Index on the relevant calculation day.

In this example, the EURO STOXX 50^® Index has the lowest performance factor and is, therefore, the lowest performing Index on the relevant calculation day.

Step 2: Determine whether a contingent coupon will be paid and whether the securities will be automatically called on the applicable quarterly contingent coupon payment date.

Since the hypothetical closing level of the lowest performing Index on the relevant calculation day is greater than or equal to its threshold level, but less than its starting level, you would receive a contingent coupon on the applicable contingent coupon payment date and the securities would not be automatically called. The contingent coupon would be equal to $20 per security, which is the product of $1,000 × 8.00% per annum / 4.

Example 2. The closing level of the lowest performing Index on the relevant calculation day is less than its threshold level. As a result, investors do not receive a contingent coupon on the applicable quarterly contingent coupon payment date and the securities are not automatically called.

	S&P 500® Index	Russell 2000® Index	EURO STOXX 50® Index
Hypothetical starting level:	100	100	100
Hypothetical closing level on relevant calculation day:	60	125	105
Hypothetical threshold level:	75	75	75
Performance factor (closing level on calculation day divided by starting level):	60%	125%	105%

Step 1: Determine which Index is the lowest performing Index on the relevant calculation day.

In this example, the S&P 500^® Index has the lowest performance factor and is, therefore, the lowest performing Index on the relevant calculation day.

Step 2: Determine whether a contingent coupon will be paid and whether the securities will be automatically called on the applicable quarterly contingent coupon payment date.

Since the hypothetical closing level of the lowest performing Index on the relevant calculation day is less than its threshold level, you would not receive a contingent coupon on the applicable contingent coupon payment date. In addition, the securities would not be automatically called, even though the closing levels of the better performing Indices on the relevant calculation day are greater than their starting levels. As this example illustrates, whether you receive a contingent coupon and whether the securities are automatically called on a quarterly contingent coupon payment date will depend solely on the closing level of the

lowest performing Index on the relevant calculation day. The performance of the better performing Indices is not relevant to your return on the securities.

Example 3. The closing level of the lowest performing Index on the relevant calculation day is greater than or equal to its starting level. As a result, the securities are automatically called on the applicable quarterly contingent coupon payment date for the original offering price plus a final contingent coupon.

	S&P 500® Index	Russell 2000® Index	EURO STOXX 50® Index
Hypothetical starting level:	100	100	100
Hypothetical closing level on relevant calculation day:	115	105	130
Hypothetical threshold level:	75	75	75
Performance factor (closing level on calculation day divided by starting level):	115%	105%	130%

Step 1: Determine which Index is the lowest performing Index on the relevant calculation day.

In this example, the Russell 2000^® Index has the lowest performance factor and is, therefore, the lowest performing Index on the relevant calculation day.

Step 2: Determine whether a contingent coupon will be paid and whether the securities will be automatically called on the applicable quarterly contingent coupon payment date.

Since the hypothetical closing level of the lowest performing Index on the relevant calculation day is greater than or equal to its starting level, the securities would be automatically called and you would receive the original offering price plus a final contingent coupon on the applicable contingent coupon payment date, which is also referred to as the call settlement date. On the call settlement date, you would receive $1,020 per security.

If the securities are automatically called prior to stated maturity, you will not receive any further payments after the call settlement date.

Hypothetical Contingent Coupons (Continued)

Set forth below are three examples of calculations of the redemption amount payable at stated maturity, assuming that the securities have not been automatically called prior to stated maturity and assuming the hypothetical starting level, threshold level and ending levels for each Index indicated in the examples. The terms used for purposes of these hypothetical examples do not represent any actual starting level or threshold level. The hypothetical starting level of 100 for each Index has been chosen for illustrative purposes only and does not represent the actual starting level for any Index. The actual starting level and threshold level for each Index will be determined on the pricing date and will be set forth under “Terms of the Securities” above. For historical data regarding the actual closing levels of the Indices, see the historical information set forth herein. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis.

Example 1. The ending level of the lowest performing Index is greater than its starting level, the redemption amount is equal to the original offering price of your securities at stated maturity and you receive a final contingent coupon:

	S&P 500® Index	Russell 2000® Index	EURO STOXX 50® Index
Hypothetical starting level:	100	100	100
Hypothetical ending level:	145	135	125
Hypothetical threshold level:	75	75	75
Performance factor (ending level divided by starting level):	145%	135%	125%

Step 1: Determine which Index is the lowest performing Index on the final calculation day.

In this example, the EURO STOXX 50^® Index has the lowest performance factor and is, therefore, the lowest performing Index on the final calculation day.

Step 2: Determine the redemption amount based on the ending level of the lowest performing Index.

Since the hypothetical ending level of the lowest performing Index is greater than its hypothetical threshold level, the redemption amount would equal the original offering price. Although the hypothetical ending level of the lowest performing Index is significantly greater than its hypothetical starting level in this scenario, the redemption amount will not exceed the original offering price.

In addition to any contingent coupons received during the term of the securities, at stated maturity you would receive $1,000 per security as well as a final contingent coupon.

Example 2. The ending level of the lowest performing Index is less than its starting level but greater than its threshold level, the redemption amount is equal to the original offering price of your securities at stated maturity and you receive a final contingent coupon:

	S&P 500® Index	Russell 2000® Index	EURO STOXX 50® Index
Hypothetical starting level:	100	100	100
Hypothetical ending level:	85	115	110
Hypothetical threshold level:	75	75	75
Performance factor (ending level divided by starting level):	85%	115%	110%

Step 1: Determine which Index is the lowest performing Index on the final calculation day.

In this example, the S&P 500^® Index has the lowest performance factor and is, therefore, the lowest performing Index on the final calculation day.

Step 2: Determine the redemption amount based on the ending level of the lowest performing Index.

Since the hypothetical ending level of the lowest performing Index is less than its hypothetical starting level, but greater than or equal to its threshold level, you would be repaid the original offering price of your securities at stated maturity.

In addition to any contingent coupons received during the term of the securities, at stated maturity you would receive $1,000 per security as well as a final contingent coupon.

Hypothetical Contingent Coupons (Continued)

Example 3. The ending level of the lowest performing Index is less than its threshold level, the redemption amount is less than the original offering price of your securities at stated maturity and you do not receive a final contingent coupon:

	S&P 500® Index	Russell 2000® Index	EURO STOXX 50® Index
Hypothetical starting level:	100	100	100
Hypothetical ending level:	120	45	90
Hypothetical threshold level:	75	75	75
Performance factor (ending level divided by starting level):	120%	45%	90%

Step 1: Determine which Index is the lowest performing Index on the final calculation day.

In this example, the Russell 2000^® Index has the lowest performance factor and is, therefore, the lowest performing Index on the final calculation day.

Step 2: Determine the redemption amount based on the ending level of the lowest performing Index.

Since the hypothetical ending level of the lowest performing Index is less than its threshold level, you would lose a portion of the original offering price of your securities and receive the redemption amount equal to $450 per security, calculated as follows:

= $1,000 × performance factor of the lowest performing Index on the final calculation day

= $1,000 × 45%

= $450

In addition to any contingent coupons received during the term of the securities, at stated maturity you would receive $450 per security, but no final contingent coupon.

These examples illustrate that you will not participate in any appreciation of any Index, but will be fully exposed to a decrease in the lowest performing Index from its starting level to its ending level if the ending level of the lowest performing Index is less than its threshold level, even if the ending levels of the other Indices have appreciated or have not declined below their respective threshold level.

To the extent that the starting level, threshold level and ending level of the lowest performing Index differ from the values assumed above, the results indicated above would be different.

· determine whether a market disruption event has occurred;

· determine the closing levels of the Indices under certain circumstances;

· determine if adjustments are required to the closing level of an Index under various circumstances; and

· if publication of an Index is discontinued, select a successor equity index (as defined below) or, if no successor equity index is available, determine the closing level of such Index.

All determinations made by the calculation agent will be at the sole discretion of the calculation agent and, in the absence of manifest error, will be conclusive for all purposes and binding on us and you. The calculation agent will have no liability for its determinations.

Market Disruption Events

A “market disruption event” with respect to the S&P 500^® Index or the Russell 2000^® Index means any of the following events as determined by the calculation agent in its sole discretion:

(A) The occurrence or existence of a material suspension of or limitation imposed on trading by the relevant stock exchanges or otherwise relating to securities which then comprise 20% or more of the level of such Index or any successor equity index at any time during the one-hour period that ends at the close of trading on that day, whether by reason of movements in price exceeding limits permitted by those relevant stock exchanges or otherwise.

(B) The occurrence or existence of a material suspension of or limitation imposed on trading by any related futures or options exchange or otherwise in futures or options contracts relating to such Index or any successor equity index on any related futures or options exchange at any time during the one-hour period that ends at the close of trading on that day, whether by reason of movements in price exceeding limits permitted by the related futures or options exchange or otherwise.

(C) The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market values for, securities that then comprise 20% or more of the level of such Index or any successor equity index on their relevant stock exchanges at any time during the one-hour period that ends at the close of trading on that day.

(4) an “exchange business day” means any trading day for such Index or any successor equity index on which each relevant stock exchange for the securities underlying such Index or any successor equity index and each related futures or options exchange with respect to such Index or any successor equity index are open for trading during their respective regular trading sessions, notwithstanding any such relevant stock exchange or related futures or options exchange closing prior to its scheduled closing time.

A “market disruption event” with respect to the EURO STOXX 50^® Index means, any of (A), (B), (C) or (D) below, as determined by the calculation agent in its sole discretion:

(A) Any of the following events occurs or exists with respect to any security included in such Index or any successor equity index, and the aggregate of all securities included in such Index or successor equity index with respect to which any such event occurs comprise 20% or more of the level of such Index or successor equity index:

(D) Any related futures or options exchange fails to open for trading during its regular trading session.

For purposes of determining whether a market disruption event has occurred with respect to the EURO STOXX 50^® Index:

(1) the relevant percentage contribution of a security included in such Index or any successor equity index to the level of such Index will be based on a comparison of (x) the portion of the level of such index attributable to that security to (y) the overall level of such index, in each case using the official opening weightings as published by the relevant index sponsor as part of the market opening data;

(2) the “scheduled closing time” of any relevant stock exchange or related futures or options exchange on any trading day means the scheduled weekday closing time of such relevant stock exchange or related futures or options exchange on such trading day, without regard to after hours or any other trading outside the regular trading session hours; and

(3) an “exchange business day” means any trading day on which (i) the relevant index sponsor publishes the level of such index or any successor equity index and (ii) each related futures or options exchange is open for trading during its regular trading session, notwithstanding any related futures or options exchange closing prior to its scheduled closing time.

If a market disruption event occurs or is continuing with respect to an Index on any calculation day, then such calculation day for such Index will be postponed to the first succeeding trading day for such Index on which a market disruption event for such Index has not occurred and is not continuing; however, if such first succeeding trading day has not occurred as of the eighth trading day for such Index after the originally scheduled calculation day, that eighth trading day shall be deemed to be the calculation day for such Index. If a calculation day has been postponed eight trading days for an Index after the originally scheduled calculation day and a market disruption event occurs or is continuing with respect to such Index on such eighth trading day, the calculation agent will determine the closing level of such Index on such eighth trading day in accordance with the formula for and method of calculating the closing level of such Index last in effect prior to commencement of the market disruption event, using the closing price (or, with respect to any relevant security, if a market disruption event has occurred with respect to such security, its good faith estimate of the value of such security at (i) with respect to the S&P 500^® Index or the Russell 2000^® Index, the scheduled closing time of the relevant stock exchange for such security or, if earlier, the actual closing time of the regular trading session of such relevant stock exchange or (ii) with respect to the EURO STOXX 50^® Index, the time at which the official closing level of such Index is calculated and published by the relevant index sponsor) on such date of each security included in such Index.

As used herein, “closing price” means, with respect to any security on any date, the relevant stock exchange traded or quoted price of such security as of (i) with respect to the S&P 500^® Index or the Russell 2000^® Index, the scheduled closing time of the relevant stock exchange for such security or, if earlier, the actual closing time of the regular trading session of such relevant stock exchange or (ii)

with respect to the EURO STOXX 50^® Index, the time at which the official closing level of such Index is calculated and published by the relevant index sponsor. Notwithstanding the postponement of a calculation day for an Index due to a market disruption event with respect to such Index on such calculation day, the originally scheduled calculation day will remain the calculation day for any Index not affected by a market disruption event on such day.

Adjustments to an Index

If at any time the method of calculating an Index or a successor equity index, or the closing level thereof, is changed in a material respect, or if an Index or a successor equity index is in any other way modified so that such index does not, in the opinion of the calculation agent, fairly represent the level of such index had those changes or modifications not been made, then the calculation agent will, at the close of business in New York, New York, on each date that the closing level of such index is to be calculated, make such calculations and adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a level of an index comparable to such Index or successor equity index as if those changes or modifications had not been made, and the calculation agent will calculate the closing level of such Index or successor equity index with reference to such index, as so adjusted. Accordingly, if the method of calculating an Index or successor equity index is modified so that the level of such index is a fraction or a multiple of what it would have been if it had not been modified (e.g., due to a split or reverse split in such equity index), then the calculation agent will adjust such Index or successor equity index in order to arrive at a level of such index as if it had not been modified (e.g., as if the split or reverse split had not occurred).

Discontinuance of an Index

If a sponsor or publisher of an Index (each, an “index sponsor”) discontinues publication of an Index, and such index sponsor or another entity publishes a successor or substitute equity index that the calculation agent determines, in its sole discretion, to be comparable to such Index (a “successor equity index”), then, upon the calculation agent’s notification of that determination to the trustee and Credit Suisse, the calculation agent will substitute the successor equity index as calculated by the relevant index sponsor or any other entity for purposes of calculating the closing level of such Index on any date of determination. Upon any selection by the calculation agent of a successor equity index, Credit Suisse will cause notice to be given to holders of the securities.

In the event that an index sponsor discontinues publication of an Index prior to, and the discontinuance is continuing on, a calculation day and the calculation agent determines that no successor equity index is available at such time, the calculation agent will calculate a substitute closing level for such Index in accordance with the formula for and method of calculating such Index last in effect prior to the discontinuance, but using only those securities that comprised such Index immediately prior to that discontinuance. If a successor equity index is selected or the calculation agent calculates a level as a substitute for such Index, the successor equity index or level will be used as a substitute for such Index for all purposes, including the purpose of determining whether a market disruption event exists.

If on a calculation day an index sponsor fails to calculate and announce the level of an Index, the calculation agent will calculate a substitute closing level of such Index in accordance with the formula for and method of calculating such Index last in effect prior to the failure, but using only those securities that comprised such Index immediately prior to that failure; provided that, if a market disruption event occurs or is continuing on such day with respect to such Index, then the provisions set forth above under “—Market Disruption Events” shall apply in lieu of the foregoing.

Notwithstanding these alternative arrangements, discontinuance of the publication of, or the failure by the relevant index sponsor to calculate and announce the level of, an Index may adversely affect the value of the securities.

United States Federal Tax Considerations

This discussion supplements and, to the extent inconsistent therewith, supersedes the discussion in the accompanying product supplement under “Material United States Federal Income Tax Considerations.”

Due to the lack of any controlling legal authority, there is substantial uncertainty regarding the U.S. federal tax consequences of an investment in the securities. In the opinion of our counsel, Davis Polk & Wardwell LLP, it is reasonable under current law to treat the securities for U.S. federal income tax purposes as prepaid financial contracts with associated coupons that will be treated as gross income to you at the time received or accrued in accordance with your regular method of tax accounting. However, our counsel has advised us that it is unable to conclude affirmatively that this treatment is more likely than not to be upheld, and that alternative treatments are possible that could materially affect the timing and character of income or loss you recognize on the securities. Moreover, our counsel’s opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date.

Assuming this treatment of the securities is respected and subject to the discussion in “Material United States Federal Income Tax Considerations” in the accompanying product supplement, the following U.S. federal income tax consequences should result:

· Any coupons paid on the securities should be 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.

· Upon a sale or other disposition (including retirement) of a security, you should recognize capital 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 coupon paid on retirement and may not include sale proceeds attributable to an accrued coupon, which may be treated as a coupon payment. Such gain or loss should be long-term capital gain or loss if you held the security for more than one year.

We do not plan to request a ruling from the IRS regarding the treatment of the securities, and the IRS or a court might not agree with the treatment described herein. In particular, the securities might be determined to be contingent payment debt instruments, in which case the tax consequences of ownership and disposition of the securities, including the timing and character of income recognized, might be materially and adversely affected. Moreover, 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 consult your tax advisor regarding possible alternative tax treatments of the securities and potential changes in applicable law.

Non-U.S. Holders. The U.S. federal income tax treatment of the coupons is unclear. Except as provided below and in the accompanying product supplement under “Material United States Federal Income Tax Considerations—Securities Held Through Foreign Entities” and “Material United States Federal Income Tax Considerations—Non-U.S. Holders Generally—Substitute Dividend and Dividend Equivalent Payments,” we currently do not intend to treat coupons paid to a Non-U.S. Holder (as defined in the accompanying product supplement) of the securities as subject to U.S. federal withholding tax, provided that the Non-U.S. Holder complies with applicable certification requirements. However, 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.

Moreover, as discussed under “Material United States Federal Income Tax Considerations—Non-U.S. Holders Generally—Substitute Dividend and Dividend Equivalent Payments” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code generally imposes a 30% withholding tax on “dividend equivalents” paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. Treasury regulations under Section 871(m), as modified by an IRS notice, exclude from their scope financial instruments issued prior to January 1, 2021 that do not have a “delta” of one with respect to any U.S. equity. Based on the terms of the securities and representations provided by us as of the date of this preliminary pricing supplement, our counsel is of the opinion that the securities should not be treated as transactions that have a “delta” of one within the meaning of the regulations with respect to any U.S. equity and, therefore, should not be subject to withholding tax under Section 871(m). However, the final determination regarding the treatment of the securities under Section 871(m) will be made as of the pricing date for the securities and it is possible that the securities will be subject to withholding tax under Section 871(m) based on circumstances on that date.

United States Federal Tax Considerations (Continued)

A determination that the securities are not subject to Section 871(m) is not binding on the IRS, and the IRS may disagree with this determination. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to a U.S. equity to which the securities relate. You should consult your tax advisor regarding the potential application of Section 871(m) to the securities.

We will not be required to pay any additional amounts with respect to U.S. federal withholding taxes.

FATCA. You should review the section entitled “Material United States Federal Income Tax Considerations—Securities Held Through Foreign Entities” in the accompanying product supplement regarding withholding rules under the “FATCA” regime. The discussion in that section is hereby modified to reflect regulations proposed by the U.S. Treasury Department indicating an intent to eliminate the requirement under FATCA of withholding on gross proceeds of the disposition of affected financial instruments. The U.S. Treasury Department has indicated that taxpayers may rely on these proposed regulations pending their finalization.

You should read the section entitled “Material United States Federal Income Tax Considerations” in the accompanying product supplement. The preceding discussion, when read in combination with that section, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of owning and disposing of the securities.

You should also consult your tax advisor regarding all aspects of the U.S. federal income and estate tax consequences of an investment in the securities and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
