Investments Credit Suisse
$ Knock-Out Notes due January 7, 2020 Linked to the Performance of the Lowest Performing of the PowerShares QQQ Trust^SM, Series 1 and the iShares^® MSCI Emerging Markets ETF 

• The notes are designed for investors who seek a fixed return at maturity linked to the performance of the lowest performing of the PowerShares QQQ Trust^SM, Series 1 and the iShares^® MSCI Emerging Markets ETF. If a Knock-Out Event has not occurred, at maturity investors will receive $1,148 per $1,000 principal amount of notes. If a Knock-Out Event has occurred, investors will receive a Payment at Maturity that will reflect the performance of the Lowest Performing Underlying, subject to the Maximum Return, and you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, if the Final Level of the Lowest Performing Underlying is less than its Initial Level, the Payment at Maturity you will receive will be less than the principal amount of the notes, and you will lose your entire investment if the Final Level of the Lowest Performing Underlying falls to zero.

• A Knock-Out Event may occur on any trading day during the Monitoring Period, regardless of the Final Level of the Lowest Performing Underlying.

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

• Senior unsecured obligations of Credit Suisse AG, acting through its London branch, maturing January 7, 2020.

• Minimum purchase of $10,000. Minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

• The offering price for the notes is expected to be determined on or about December 21, 2018 (the “Pricing Date”), and the notes are expected to settle on or about December 27, 2018 (the “Settlement Date”). Delivery of the notes in book-entry form only will be made through The Depository Trust Company.

Hypothetical Payments at Maturity for Each $1,000 Principal Amount of Notes

The following table and examples illustrate the hypothetical Payments at Maturity for a $1,000 principal amount of notes for a hypothetical range of performance of the Lowest Performing Underlying.

The tables and examples below assume that (i) the Maximum Return is 14.80% and (ii) the Knock-Out Level is 70%. The actual Maximum Return and Knock-Out Level will be determined on the Strike Date.

The hypothetical Payments at Maturity set forth below are for illustrative purposes only. The actual Payment at Maturity applicable to a purchaser of the notes will depend on the Final Level of the Lowest Performing Underlying and on whether a Knock-Out Event occurs. It is not possible to predict whether a Knock-Out Event will occur. In the event that there is a Knock-Out Event, it is not possible to predict whether and by how much the level of the Lowest Performing Underlying has decreased from its Initial Level to its Final Level. You should consider carefully whether the notes are suited to your investment goals. Any payment on the notes is subject to our ability to pay our obligations as they become due. The numbers appearing in the tables and examples below have been rounded for ease of analysis.

Hypothetical Examples of Amounts Payable at Maturity

EXAMPLES:

The following examples illustrate how the Payment at Maturity is calculated.

Example 1: A Knock-Out Event has not occurred and the level of the Lowest Performing Underlying increases by 70% from its Initial Level to its Final Level.

Underlying	Lowest closing level during the Monitoring Period	Final Level
QQQ	90% of Initial Level	170% of Initial Level
EEM	80% of Initial Level	180% of Initial Level

Because the closing level of each Underlying is not less than its Knock-Out Level on any trading day during the Monitoring Period, a Knock-Out Event has not occurred and the Payment at Maturity is determined as follows:

Payment at Maturity	=	$1,000 + ($1,000 × Maximum Return)
	=	$1,000 + $148
	=	$1,148

The Payment at Maturity will not exceed $1,000 plus the product of $1,000 and the Maximum Return, regardless of the appreciation of any Underlying.

Example 2: A Knock-Out Event has not occurred and the level of the Lowest Performing Underlying increases by 5% from its Initial Level to its Final Level.

Underlying	Lowest closing level during the Monitoring Period	Final Level
QQQ	90% of Initial Level	105% of Initial Level
EEM	80% of Initial Level	120% of Initial Level

Because the closing level of each Underlying is not less than its Knock-Out Level on any trading day during the Monitoring Period, a Knock-Out Event has not occurred and the Payment at Maturity is determined as follows:

Payment at Maturity	=	$1,000 + ($1,000 × Maximum Return)
	=	$1,000 + $148
	=	$1,148

Because a Knock-Out Event has not occurred, the Payment at Maturity is equal to $1,000 plus the product of $1,000 and the Maximum Return.

Example 3: A Knock-Out Event has occurred and the level of the Lowest Performing Underlying increases by 70% from its Initial Level to its Final Level.

Underlying	Lowest closing level during the Monitoring Period	Final Level
QQQ	50% of Initial Level	170% of Initial Level
EEM	80% of Initial Level	180% of Initial Level

Because a Knock-Out Event has occurred and the Final Level of the Lowest Performing Underlying is greater than its Initial Level, the Payment at Maturity is determined as follows:

Payment at Maturity	=	$1,000 + ($1,000 x the lesser of (i) Underlying Return and (ii) Maximum Return)
	=	$1,000 + ($1,000 x the lesser of (i) 70% and (ii) 14.80%)

4 

=	$1,000 + ($1,000 x 14.80%)
=	$1,000 + ($1,000 × 0.148)
	$1,000 + $148
=	$1,148

The Payment at Maturity will not exceed $1,000 plus the product of $1,000 and the Maximum Return, regardless of the appreciation of any Underlying.

Example 4: A Knock-Out Event has occurred and the level of the Lowest Performing Underlying increases by 5% from its Initial Level to its Final Level.

Underlying	Lowest closing level during the Monitoring Period	Final Level
QQQ	50% of Initial Level	105% of Initial Level
EEM	80% of Initial Level	120% of Initial Level

Because a Knock-Out Event has occurred and the Final Level of the Lowest Performing Underlying is greater than its Initial Level, but less than the Maximum Return, the Payment at Maturity is determined as follows:

Payment at Maturity	=	$1,000 + ($1,000 x the lesser of (i) Underlying Return and (ii) Maximum Return)
	=	$1,000 + ($1,000 x the lesser of (i) 5% and (ii) 14.80%)
	=	$1,000 + ($1,000 x 5%)
	=	$1,000 + ($1,000 × 0.05)
	=	$1,050

Because a Knock-Out Event has occurred and the Final Level of the Lowest Performing Underlying has increased, but by an amount less than the Maximum Return, the investor receives a Payment at Maturity that is equal to the appreciation of the Lowest Performing Underlying.  

Example 5: A Knock-Out Event has occurred and the level of the Lowest Performing Underlying decreases by 20% from its Initial Level to its Final Level.

Underlying	Lowest closing level during the Monitoring Period	Final Level
QQQ	50% of Initial Level	80% of Initial Level
EEM	80% of Initial Level	140% of Initial Level

Because a Knock-Out Event has occurred and the Final Level of the Lowest Performing Underlying is less than its Initial Level, the Payment at Maturity is determined as follows:

Payment at Maturity	=	$1,000 + ($1,000 x the lesser of (i) Underlying Return and (ii) Maximum Return)
	=	$1,000 + ($1,000 x the lesser of (i) -20% and (ii) 14.80%)
	=	$1,000 + ($1,000 × -0.20)
	=	$1,000 - $200
	=	$800

Because a Knock-Out Event has occurred and the Final Level of the Lowest Performing Underlying is less than its Initial Level, you will be exposed to any depreciation in the level of the Lowest Performing Underlying from its Initial Level to its Final Level.

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the Underlyings. These risks are explained in more detail in the “Risk Factors” section of any accompanying product supplement.

• YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — You may receive less at maturity than you originally invested in the notes, or you may receive nothing. If a Knock-Out Event has occurred, you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, if the Final Level of the Lowest Performing Underlying is less than its Initial Level, the Payment at Maturity you will receive will be less than the principal amount of the notes, and you will lose your entire investment if the Final Level of the Lowest Performing Underlying falls to zero. It is not possible to predict whether a Knock-Out Event will occur, and in the event that there is a Knock-Out Event,  whether and by how much the level of the Lowest Performing Underlying has decreased from its Initial Level to its Final Level. Any payment on the notes is subject to our ability to pay our obligations as they become due.

• REGARDLESS OF THE AMOUNT OF ANY PAYMENT YOU RECEIVE ON THE NOTES, YOUR ACTUAL YIELD MAY BE DIFFERENT IN REAL VALUE TERMS — Inflation may cause the real value of any payment you receive on the notes to be less at maturity than it is at the time you invest. An investment in the notes 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 NOTES DO NOT PAY INTEREST — We will not pay interest on the notes. You may receive less at maturity than you could have earned on ordinary interest-bearing debt securities with similar maturities, including other of our debt securities, since the Payment at Maturity is based on the performance of the Lowest Performing Underlying. Because the payment due at maturity may be less than the amount originally invested in the notes, the return on the notes (the effective yield to maturity) may be negative. Even if it is positive, the return payable on the notes may not be enough to compensate you for any loss in value due to inflation and other factors relating to the value of money over time.

· THE NOTES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE — Investors are dependent on our ability to pay all amounts due on the notes and, therefore, if we were to default on our obligations, you may not receive any amounts owed to you under the notes. 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 notes prior to maturity.

· THE AVERAGING CONVENTION USED TO CALCULATE THE FINAL LEVEL COULD LIMIT RETURNS — Your investment in the notes may not perform as well as an investment in an instrument that measures the point-to-point performance of the Lowest Performing Underlying from the Pricing Date to the Final Valuation Date (subject to the Maximum Return). Your ability to receive a return equal to the Maximum Return may be limited by the 5-day-end-of-term averaging used to calculate the Final Level, especially if there is a significant increase in the closing level of the Lowest Performing Underlying on the Final Valuation Date. Accordingly, you may not receive the benefit of the full appreciation of the Lowest Performing Underlying, if any, between the Pricing Date and the Final Valuation Date.

· YOU MAY BE SUBJECT TO POTENTIAL LOSS OF PRINCIPAL REGARDLESS OF THE FINAL LEVEL OF THE LOWEST PERFORMING UNDERLYING — If, on any trading day during the Monitoring Period, the closing level of any Underlying is less than its Knock-Out Level, a Knock-Out Event will occur and you will be subject to loss of principal if the Final Level of the Lowest Performing Underlying is less than its Initial Level.

· THE PROBABILITY THAT A KNOCK-OUT EVENT WILL OCCUR AND THE FINAL LEVEL OF THE LOWEST PERFORMING UNDERLYING WILL BE LESS THAN ITS INITIAL LEVEL WILL DEPEND ON THE VOLATILITY OF SUCH UNDERLYING — “Volatility” refers to the frequency and magnitude of changes in the level of an Underlying. The greater the expected volatility with respect to an Underlying on the Pricing Date, the higher the expectation as of the Pricing Date that a Knock-Out Event could occur and the Final Level of the Lowest Performing Underlying could be less than its Initial Level, indicating a higher expected risk of loss on the notes. The terms of the notes are set, in part, based on expectations about the volatility of the Underlyings as of the Pricing Date. The volatility of any Underlying can change significantly over the term of the notes. The level of any Underlying could fall sharply, which could result in

6 

a significant loss of principal. You should be willing to accept the downside market risk of the Underlyings and the potential to lose a significant amount of your principal at maturity.

· IF A KNOCK-OUT EVENT HAS OCCURRED AND THE FINAL LEVEL OF THE LOWEST PERFORMING UNDERLYING IS LESS THAN ITS INITIAL LEVEL, YOU WILL RECEIVE LESS THAN YOUR PRINCIPAL AMOUNT AT MATURITY EVEN IF THE FINAL LEVEL OF THE LOWEST PERFORMING UNDERLYING IS LESS THAN ITS KNOCK-OUT LEVEL — If a Knock-Out Event has occurred, you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, if the Final Level of the Lowest Performing Underlying is less than its Initial Level, the Payment at Maturity will be less than the principal amount of the notes, and you will lose your entire investment if the Final Level of the Lowest Performing Underlying is zero. In this case, even if the Final Level of the Lowest Performing Underlying is less than its Knock-Out Level, the payment at maturity will be less than $1,000 per $1,000 principal amount.

· LIMITED APPRECIATION POTENTIAL — Regardless of whether a Knock-Out Event does not occur, for each $1,000 principal amount of notes, the maximum Payment at Maturity is $1,000 plus $1,000 multiplied by the Maximum Return, regardless of the appreciation in the level of the Lowest Performing Underlying, which may be significant.

· YOU WILL BE SUBJECT TO RISKS RELATING TO THE RELATIONSHIP BETWEEN THE UNDERLYINGS — The notes are linked to the individual performance of each Underlying. As such, the notes will perform poorly if only one of the Underlyings performs poorly. For example, if one Underlying appreciates from its Initial Level to its Final Level, but a Knock-Out Event has occurred, you will be exposed to the depreciation of the Lowest Performing Underlying and you will not benefit from the performance of any other Underlying. Each additional Underlying to which the notes are linked increases the risk that the notes will perform poorly. By investing in the notes, you assume the risk that (i) a Knock-Out Event occurs with respect to at least one of the Underlyings and (ii) if a Knock-Out Event has occurred, the Final Level of at least one of the Underlyings will be less than its Initial Level, regardless of the performance of any other Underlying.

It is impossible to predict the relationship between the Underlyings. If the performances of the Underlyings exhibit no relationship to each other, it is more likely that one of the Underlyings will cause the notes to perform poorly. However, if the performances of the equity securities included in each Underlying are related such that the performances of the Underlyings are correlated, then there is less likelihood that only one Underlying will cause the notes to perform poorly. Furthermore, to the extent that each Underlying represents a different market segment or market sector, the risk of one Underlying performing poorly is greater. As a result, you are not only taking market risk on each Underlying, you are also taking a risk relating to the relationship among the Underlyings.

· THERE ARE RISKS ASSOCIATED WITH THE UNDERLYINGS — Although shares of the Underlyings are listed for trading on a national securities exchange and a number of similar products have been traded on various national securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of the Underlyings or that there will be liquidity in the trading market. The Underlyings are subject to management risk, which is the risk that an Underlying’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Pursuant to each Underlying's investment strategy or otherwise, its investment advisor may add, delete or substitute the assets held by the Underlyings. Any of these actions could adversely affect the price of the shares of the Underlyings and consequently the value of the notes. For additional information on the Underlyings, see “The Underlyings” herein.

• THE PERFORMANCE AND MARKET VALUE OF EACH UNDERLYING, PARTICULARLY DURING PERIODS OF MARKET VOLATILITY, MAY NOT CORRELATE TO THE PERFORMANCE OF ITS TRACKED INDEX — Each Underlying will generally invest in all of the equity securities included in the index tracked by such Underlying (each such index, a “Tracked Index”), but may not fully replicate such Tracked Index. There may be instances where a Underlying’s investment advisor may choose to overweight another stock in such Underlying’s Tracked Index, purchase securities not included in such Underlying’s Tracked Index that such investment advisor believes are appropriate to substitute for a security included in such Tracked Index or utilize various combinations of other available investment techniques. In addition, the performance of each Underlying will reflect additional transaction costs and

7 

fees that are not included in the calculation of such Underlying’s Tracked Index. Finally, because the shares of each Underlying are traded on a national securities exchange and are subject to market supply and investor demand, the market value of one share of each Underlying may differ from the net asset value per share of such Underlying.

During periods of market volatility, securities held by each Underlying may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of such Underlying and the liquidity of such Underlying may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in each Underlying. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of each Underlying. As a result, under these circumstances, the market value of shares of each Underlying may vary substantially from the net asset value per share of such Underlying. For all the foregoing reasons, the performance of each Underlying may not correlate with the performance of its Tracked Index. For additional information on the Underlyings, see “The Underlyings” herein.

• EMERGING MARKETS RISK — The iShares^® MSCI Emerging Markets ETF is exposed to the political and economic risks of emerging market countries. In recent years, some emerging markets have undergone significant political, economic and social upheaval. Such far-reaching changes have resulted in constitutional and social tensions and, in some cases, instability and reaction against market reforms has occurred. With respect to any emerging market nation, there is the possibility of nationalization, expropriation or confiscation, political changes, government regulation and social instability. There can be no assurance that future political changes will not adversely affect the economic conditions of an emerging market nation. Political or economic instability could have an adverse effect on the performance of the notes.

• CURRENCY EXCHANGE RISK — Because the prices of the equity securities included in the iShares^® MSCI Emerging Markets ETF are converted into U.S. dollars for purposes of calculating the level of the iShares^® MSCI Emerging Markets ETF, investors will be exposed to currency exchange rate risk with respect to each of the currencies in which the equity securities included in the iShares^® MSCI Emerging Markets ETF trade. Currency exchange rates may be highly volatile, particularly in relation to emerging or developing nations’ currencies and, in certain market conditions, also in relation to developed nations’ currencies. Significant changes in currency exchange rates, including changes in liquidity and prices, can occur within very short periods of time. Currency exchange rate risks include, but are not limited to, convertibility risk, market volatility and potential interference by foreign governments through regulation of local markets, foreign investment or particular transactions in foreign currency. These factors may adversely affect the values of the equity securities included in the iShares^® MSCI Emerging Markets ETF, the level of the iShares^® MSCI Emerging Markets ETF and the value of the notes.

• FOREIGN SECURITIES MARKETS RISK — Some or all of the assets included in the iShares^® MSCI Emerging Markets ETF are issued by foreign companies and trade in foreign securities markets. Investments in the notes 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 iShares^® MSCI Emerging Markets ETF 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 iShares^® MSCI Emerging Markets ETF, and therefore the performance of the iShares^® MSCI Emerging Markets ETF and the value of the notes.

• HEDGING AND TRADING ACTIVITY — We, any dealer or any of our or their respective affiliates may carry out hedging activities related to the notes, including in the Underlyings or instruments related to the Underlyings. We, any dealer or our or their respective affiliates may also trade in the Underlyings or instruments related to the Underlyings from time to time. Any of these hedging or trading activities on or

8 

prior to the Pricing Date and during the term of the notes could adversely affect our payment to you at maturity.

· THE ESTIMATED VALUE OF THE NOTES ON THE PRICING DATE MAY BE LESS THAN THE PRICE TO PUBLIC — The initial estimated value of your notes on the Pricing 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 notes includes any discounts or commissions as well as transaction costs such as expenses incurred to create, document and market the notes and the cost of hedging our risks as issuer of the notes 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 notes. These amounts will be retained by Credit Suisse or our affiliates in connection with our structuring and offering of the notes (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 notes 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 notes 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 notes at issuance. Our option valuation models are proprietary. Our pricing models take into account factors such as interest rates, volatility and time to maturity of the notes, 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 NOTES — The internal funding rate we use in structuring notes such as these notes 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 notes will generally be less favorable to you than they would have been if our secondary market credit spread had been used in structuring the notes. We will also use our internal funding rate to determine the price of the notes if we post a bid to repurchase your notes in secondary market transactions. See “—Secondary Market Prices” below.

• SECONDARY MARKET PRICES — If Credit Suisse (or an affiliate) bids for your notes 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 notes on the Pricing Date. The estimated value of the notes on the cover of this pricing supplement does not represent a minimum price at which we would be willing to buy the notes in the secondary market (if any exists) at any time. The secondary market price of your notes 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 notes 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 notes 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 notes will be lower than the Price to Public because it will not include any discounts or commissions and hedging and other transaction costs. If you sell your notes 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 notes may be lower than the price at which we may repurchase the notes from such dealer.

We (or an affiliate) may initially post a bid to repurchase the notes from you at a price that will exceed the then-current estimated value of the notes. That higher price reflects our projected profit and costs 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

9 

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 notes 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 notes to maturity.

• 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 notes and/or the ability of Credit Suisse to make payments thereunder and you may not receive any amounts owed to you under the notes.

• POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent, hedging our obligations under the notes 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 notes. Further, hedging activities may adversely affect any payment on or the value of the notes. 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 notes, which creates an additional incentive to sell the notes to you.

• LACK OF LIQUIDITY — The notes will not be listed on any securities exchange. Credit Suisse (or its affiliates) intends to offer to purchase the notes 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 notes when you wish to do so. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which Credit Suisse (or its affiliates) is willing to buy the notes. If you have to sell your notes prior to maturity, you may not be able to do so or you may have to sell them at a substantial loss.

• UNPREDICTABLE ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE NOTES — The payout on the notes can be replicated using a combination of the components described in “The estimated value of the notes on the Pricing Date may be less than the Price to Public.” Therefore, in addition to the levels of any Underlying, the terms of the notes at issuance and the value of the notes prior to 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 Underlyings;

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

o the time to maturity of the notes;

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

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 Underlyings or markets generally and which may affect the levels of the Underlyings; and

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

10 

Some or all of these factors may influence the price that you will receive if you choose to sell your notes prior to 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 UNDERLYINGS — Your return on the notes will not reflect the return you would realize if you actually owned shares of the Underlyings or the assets that comprise the Underlyings. The return on your investment is not the same as the total return you would receive based on the purchase of shares of the Underlyings or the assets that comprise the Underlyings.

• NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the notes, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to the shares of the Underlyings or the assets that comprise the Underlyings.

• ANTI-DILUTION PROTECTION IS LIMITED — The calculation agent will make anti-dilution adjustments for certain events affecting the Underlyings. However, an adjustment will not be required in response to all events that could affect the Underlyings. If an event occurs that does not require the calculation agent to make an adjustment, or if an adjustment is made but such adjustment does not fully reflect the economics of such event, the value of the notes may be materially and adversely affected. See “Description of the Notes—Adjustments—For a reference fund” in the relevant product supplement.

• THE U.S. FEDERAL TAX CONSEQUENCES OF AN INVESTMENT IN THE NOTES ARE UNCLEAR — There is no direct legal authority regarding the proper U.S. federal tax treatment of the notes, 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 notes are uncertain, and the IRS or a court might not agree with the treatment of the notes as prepaid financial contracts that are treated as “open transactions.”  If the IRS were successful in asserting an alternative treatment of the notes, the tax consequences of the ownership and disposition of the notes, 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.  Even if the treatment of the notes described herein is respected, there is a risk that a note will be treated as a “constructive ownership transaction,” with potentially adverse consequences described below under “United States Federal Tax Considerations.”  Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the notes, possibly retroactively.

Supplemental Use of Proceeds and Hedging

We intend to use the proceeds of this offering for our general corporate purposes, which may include the refinancing of existing debt outside Switzerland. Some or all of the proceeds we receive from the sale of the notes may be used in connection with hedging our obligations under the notes through one or more of our affiliates. Such hedging or trading activities on or prior to the Pricing Date and during the term of the notes (including on any calculation date, as defined in any accompanying product supplement) could adversely affect the value of the Underlyings and, as a result, could decrease the amount you may receive on the notes at maturity. For additional information, see “Supplemental Use of Proceeds and Hedging” in any accompanying product supplement.

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.”  

There are no statutory, judicial or administrative authorities that address the U.S. federal income tax treatment of the notes or instruments that are similar to the notes.  In the opinion of our counsel, Davis Polk & Wardwell LLP, a note should be treated as a prepaid financial contract that is an “open transaction” for U.S. federal income tax purposes.  However, there is uncertainty regarding this treatment.  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 notes 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:

· You should not recognize taxable income over the term of the notes prior to maturity, other than pursuant to a sale or other disposition.

· Upon a sale or other disposition (including retirement) of a note, you should recognize gain or loss equal to the difference between the amount realized and your tax basis in the note.  Subject to the discussion below concerning the potential application of the “constructive ownership” rules under Section 1260 of the Internal Revenue Code of 1986, as amended (the “Code”), such gain or loss should be long-term capital gain or loss if you held the note for more than one year.

Even if the treatment of the notes as described herein is respected, there is a risk that your purchase of a note will be treated as entry into a “constructive ownership transaction,” within the meaning of Section 1260 of the Code. In that case, all or a portion of any long-term capital gain you would otherwise recognize in respect of your notes would be recharacterized as ordinary income to the extent such gain exceeded the “net underlying long-term capital gain.”  Any long-term capital gain recharacterized as ordinary income under Section 1260 would be treated as accruing at a constant rate over the period you held your notes, and you would be subject to an interest charge in respect of the deemed tax liability on the income treated as accruing in prior tax years. Due to the lack of governing authority under Section 1260, our counsel is not able to opine as to whether or how Section 1260 applies to the notes. You should read the section entitled “Material United States Federal Income Tax Considerations—U.S. Holders—Constructive Ownership Transaction Rules” in the accompanying product supplement for additional information and consult your tax advisor regarding the potential application of the “constructive ownership” rule.

We do not plan to request a ruling from the IRS regarding the treatment of the notes, and the IRS or a court might not agree with the treatment described herein.  In particular, the IRS could treat the notes as contingent payment debt instruments, in which case the tax consequences of ownership and disposition of the notes, including the timing and character of income recognized, could 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 notes, possibly with retroactive effect.  You should consult your tax advisor regarding possible alternative tax treatments of the notes and potential changes in applicable law.

Non-U.S. Holders.  Subject to the discussions in the next paragraph and in “Material United States Federal Income Tax Considerations” in the accompanying product supplement, if you are a Non-U.S. Holder (as defined in the accompanying product supplement) of the notes, you generally should not be subject to U.S. federal withholding or income tax in respect of any amount paid to you with respect to the notes, provided that (i) income in respect of the notes is not effectively connected with your conduct of a trade or business in the United States, and (ii) you comply with the applicable certification requirements.

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 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

14 

respect to any U.S. equity.  Based on the terms of the notes and representations provided by us as of the date of this preliminary pricing supplement, our counsel is of the opinion that the notes 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 notes under Section 871(m) will be made as of the Pricing Date for the notes and it is possible that the notes will be subject to withholding tax under Section 871(m) based on circumstances on that date.

A determination that the notes 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 notes relate.  You should consult your tax advisor regarding the potential application of Section 871(m) to the notes.

If withholding tax applies to the notes, we will not be required to pay any additional amounts with respect to amounts withheld.

FATCA. You should review the section entitled "Material United States Federal Income Tax Considerations—Notes 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 notes.  

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 notes and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Supplemental Plan of Distribution

Under the terms of distributor accession confirmations with JPMS LLC and JPMorgan Chase Bank, N.A., each dated as of June 18, 2008, JPMS LLC and JPMorgan Chase Bank, N.A. will act as placement agents for the notes. The placement agents will receive a fee from Credit Suisse or one of our affiliates that will not exceed $10 per $1,000 principal amount of notes and will forgo fees for sales to fiduciary accounts. For additional information, see “Underwriting (Conflicts of Interest)” in any accompanying product supplement.

We expect to deliver the notes against payment for the notes on the Settlement Date indicated herein, which may be a date that is greater than two business days following the Pricing Date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, if the Settlement Date is more than two business days after the Pricing Date, purchasers who wish to transact in the notes more than two business days prior to the Settlement Date will be required to specify alternative settlement arrangements to prevent a failed settlement.
