• Investors will not receive any interest or dividend payments.

• If a Barrier Event has not occurred on any trading day during the Observation Period, investors will receive the principal amount of their investment plus a return equal to the greater of (i) zero and (ii) the Underlying Performance. If a Barrier Event has not occurred, the Redemption Amount will not be greater than $1,350 (to be determined on the Trade Date) and could be as low as $1,000. If a Barrier Event has occurred, investors will receive for each $1,000 principal amount of the securities an amount equal to $1,000 multiplied by the sum of one plus the Contingent Return, which is expected to be 6% (to be determined on the Trade Date). If a Barrier Event has occurred, your return will be limited by the Contingent Return regardless of the performance of the Underlying.

Key Terms

Issuer:	Credit Suisse AG (“Credit Suisse”), acting through its London branch
Underlying:	The securities are linked to the performance of the Underlying set forth in the table below. For more information on the Underlying, see “The Underlying” herein. The Underlying is identified in the table below, together with its Bloomberg ticker symbol, Initial Level and expected Digital Barrier (each level to be determined on the Trade Date):
	Underlying	Ticker	Initial Level	Digital Barrier  (135% of the Initial Level)
	Utilities Select Sector SPDR® Fund	XLU UP <Equity>
Redemption Amount:	At maturity, for each $1,000 principal amount of securities, you will receive a Redemption Amount in cash that will equal $1,000 multiplied by the sum of one plus the Underlying Return, calculated as set forth below. Any payment on the securities is subject to our ability to pay our obligations as they become due.
Underlying Return:	The Underlying Return is expressed as a percentage and is calculated as follows:

•	If a Barrier Event has occurred, the Contingent Return.
	In this case, the Redemption Amount will be $1,060 for every $1,000 principal amount of the securities.

In this case, the maximum Redemption Amount is expected to be $1,350 for every $1,000 principal amount of the securities.

Barrier Event:	A Barrier Event will occur if, on any trading day during the Observation Period, the closing level of the Underlying is greater than the Digital Barrier.
Contingent Return:	Expected to be 6% (to be determined on the Trade Date).
Underlying Performance:	The Underlying Performance is expressed as a percentage and is calculated as follows:
	Final Level – Initial Level Initial Level
Initial Level:	The closing level of the Underlying on the Trade Date. In the event that the closing level for the Underlying is not available on the Trade Date, the Initial Level will be determined on the immediately following trading day on which a closing level is available.
Final Level:	The closing level of the Underlying on the Valuation Date.
Observation Period:	The period from but excluding the Trade Date to and including the Valuation Date.
Valuation Date:	December 14, 2021, subject to postponement as set forth in any accompanying product supplement under “Description of the Securities—Postponement of calculation dates.”

Hypothetical Redemption Amounts at Maturity

The tables and examples below illustrate the hypothetical Redemption Amounts payable at maturity on a $1,000 investment in the securities for a hypothetical range of the performance of the Underlying. The tables and examples below assume that (i) the Digital Barrier is equal to 135% of the Initial Level and (ii) the Contingent Return is 6%. The actual Digital Barrier and Contingent Return will be determined on the Trade Date. The hypothetical Redemption Amounts set forth below are provided for illustration purposes only. The actual Redemption Amount applicable to a purchaser of the securities will depend on whether a Barrier Event has occurred and the Final Level. You should consider carefully whether the securities are suitable to your investment goals. Any payment on the securities 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.

Percentage Change from the Initial Level to the Final Level	Underlying Return	Redemption Amount per $1,000 Principal Amount of Securities
35%	35%	$1,350
30%	30%	$1,300
20%	20%	$1,200

−80%	0%	$1,000
−90%	0%	$1,000
−100%	0%	$1,000

EXAMPLES:

The following examples illustrate how the Redemption Amount is calculated.

Example 1:

A Barrier Event has occurred because, on a trading day during the Observation Period, the closing level of the Underlying was greater than the Digital Barrier. The level of the Underlying increases by 90% from the Initial Level to the Final Level. Therefore, the determination of the Redemption Amount is as follows:

Underlying Return	=	Contingent Return
	=	6%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 1.06
	=	$1,060

Even though the Underlying has appreciated from the Initial Level to the Final Level, because a Barrier Event has occurred during the Observation Period, you will receive the Contingent Return and you will not benefit from the appreciation in the level of the Underlying.

4 

Example 2:

A Barrier Event has occurred because, on a trading day during the Observation Period, the closing level of the Underlying was greater than the Digital Barrier. The level of the Underlying increases by 10% from the Initial Level to the Final Level. Therefore, the determination of the Redemption Amount is as follows:

Underlying Return	=	Contingent Return
	=	6%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 1.06
	=	$1,060

Even though the Final Level is less than the Digital Barrier, because a Barrier Event has occurred during the Observation Period, you will receive the Contingent Return and you will not benefit from the appreciation in the level of the Underlying.

Example 3:

A Barrier Event has not occurred because the closing level of the Underlying on every trading day during the Observation Period was equal to or less than the Digital Barrier. The level of the Underlying increases by 30% from the Initial Level to the Final Level. Therefore, the determination of the Redemption Amount is as follows:

Underlying Return	=	the greater of (i) zero and (ii) Underlying Performance
		the greater of (i) zero and (ii) 30%
	=	30%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 1.30
	=	$1,300

Because a Barrier Event has not occurred and the Final Level is greater than the Initial Level, the Underlying Return is equal to the Underlying Performance. At maturity, you would receive a Redemption Amount of $1,300 per $1,000 principal amount of securities.

Example 4:

A Barrier Event has not occurred because the closing level of the Underlying on every trading day during the Observation Period was equal to or less than the Digital Barrier. The level of the Underlying decreases by 50% from the Initial Level to the Final Level. Therefore, the determination of the Redemption Amount is as follows:

Underlying Return	=	the greater of (i) zero and (ii) Underlying Performance
	=	the greater of (i) zero and (ii) −50%
	=	0%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 1
	=	$1,000

Because a Barrier Event has not occurred and the Final Level is less than the Initial Level, the Underlying Return is equal to 0%. At maturity, you would receive a Redemption Amount of $1,000 per $1,000 principal amount of securities. Therefore, your Redemption Amount will be less than your Redemption Amount if a Barrier Event had occurred.

Selected Risk Considerations

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

• THE SECURITIES DO NOT PAY INTEREST — We will not pay interest on the securities. 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 Redemption Amount is based on the performance of the Underlying. Even if the Redemption Amount is greater than the principal amount of your securities, the return payable on each security 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.

• 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 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 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 maturity.

• THE APPRECIATION POTENTIAL IS LIMITED — The appreciation potential of the securities is limited by the Digital Barrier. If a Barrier Event occurs during the Observation Period, you will receive a Redemption Amount for each $1,000 principal amount of securities equal to $1,000 multiplied by the sum of one plus the Contingent Return. Therefore, you will not benefit from any positive Underlying Performance above the Digital Barrier.

• IF A BARRIER EVENT DOES NOT OCCUR, THE REDEMPTION AMOUNT WILL BE SUBJECT TO AN EMBEDDED CAP — If, on every trading day during the Observation Period, the closing level of the Underlying is equal to or less than the Digital Barrier, the Redemption Amount will equal the principal amount of the securities you hold multiplied by the sum of one plus the greater of (i) zero and (ii) the Underlying Performance. In this scenario, the maximum possible Redemption Amount of the securities is $1,350 per $1,000 principal amount of securities (to be determined on the Trade Date). Any payment on the securities is subject to our ability to pay our obligations as they become due.

• IF A BARRIER EVENT DOES NOT OCCUR, THE REDEMPTION AMOUNT COULD BE LESS THAN THE CONTINGENT RETURN — If a Barrier Event does not occur and the Final Level is less than 106% of the Initial Level, the Redemption Amount could be less than the Contingent Return. In this scenario, your Redemption Amount could be less than your Redemption Amount if a Barrier Event had occurred.

• THE PROBABILITY THAT A BARRIER EVENT WILL OCCUR WILL DEPEND ON THE VOLATILITY OF THE UNDERLYING — “Volatility” refers to the frequency and magnitude of changes in the level of the Underlying. The greater the expected volatility with respect to the Underlying on the Trade Date, the higher the expectation as of the Trade Date that a Barrier Event will occur during the Observation Period. The terms of the securities are set, in part, based on expectations about the volatility of the Underlying as of the Trade Date. The volatility of the Underlying can change significantly over the term of the securities. The level of the Underlying could rise sharply, which could result in a Barrier Event occurring. You should be willing to accept the potential to lose any upside participation in the Underlying at maturity and to receive only the principal amount of $1,000 plus a return equal to the Contingent Return.

• THERE ARE RISKS ASSOCIATED WITH THE UNDERLYING — Although shares of the Underlying 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 Underlying or that there will be liquidity in the trading market. The

6 

Underlying is subject to management risk, which is the risk that the Underlying’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Pursuant to the Underlying’s investment strategy or otherwise, its investment advisor may add, delete or substitute the assets held by the Underlying. Any of these actions could adversely affect the price of the shares of the Underlying and consequently the value of the securities. For additional information on the Underlying, see “The Underlying” herein.

• THE PERFORMANCE AND MARKET VALUE OF THE UNDERLYING, PARTICULARLY DURING PERIODS OF MARKET VOLATILITY, MAY NOT CORRELATE TO THE PERFORMANCE OF THE TRACKED INDEX — The Underlying will generally invest in all of the equity securities included in the index tracked by the Underlying, the “Tracked Index,” but may not fully replicate the Tracked Index. There may be instances where the investment advisor for the Underlying may choose to overweight a stock in the Tracked Index, purchase securities not included in the Tracked Index that the investment advisor believes are appropriate to substitute for a security included in the Tracked Index or utilize various combinations of other available investment techniques. In addition, the performance of the Underlying will reflect additional transaction costs and fees that are not included in the calculation of the Tracked Index. Finally, because the shares of the Underlying are traded on a national securities exchange and are subject to market supply and investor demand, the market value of one share of the Underlying may differ from the net asset value per share of the Underlying.

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

• The Stocks Included in THE Underlying are Concentrated in One Particular Sector — All of the stocks included in the Underlying are issued by companies in a single sector. As a result, the stocks that will determine the performance of the Underlying are concentrated in a single sector. Although an investment in the securities will not give holders any ownership or other direct interests in the stocks held by the Underlying, the return on an investment in the securities will be subject to certain risks associated with a direct equity investment in companies in a single sector. Accordingly, by investing in the securities, you will not benefit from the diversification which could result from an investment linked to companies that operate in a broader range of sectors.

• HEDGING AND TRADING ACTIVITY — We or any of our affiliates may carry out hedging activities related to the securities, including in the Underlying or instruments related to the Underlying. We or our affiliates may also trade in the Underlying or instruments related to the Underlying from time to time. Any of these hedging or trading activities on or prior to the Trade Date and during the term of the securities could adversely affect our payment to you at maturity.

• THE ESTIMATED VALUE OF THE SECURITIES ON THE TRADE DATE MAY BE LESS THAN THE PRICE TO PUBLIC — The initial estimated value of your securities on the Trade Date (as determined by reference to our pricing models and our internal funding rate) may be significantly less than the original Price to Public. The Price to Public of the securities includes 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 Trade Date, we value the components of the securities in accordance with our pricing models. These include a fixed income component valued using our internal funding rate, and individual option components valued using 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

7 

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

• SECONDARY MARKET PRICES — If Credit Suisse (or an affiliate) bids for your securities in secondary market transactions, which we are not obligated to do, the secondary market price (and the value used for account statements or otherwise) may be higher or lower than the Price to Public and the estimated value of the securities on the Trade Date. The estimated value of the securities on the cover of this pricing supplement does not represent a minimum price at which we would be willing to buy the securities in the secondary market (if any exists) at any time. The secondary market price of your securities at any time cannot be predicted and will reflect the then-current estimated value determined by reference to our pricing models and other factors. 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 Trade Date, the secondary market price of your securities 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 securities to a dealer in a secondary market transaction, the dealer may impose an additional discount or commission, and as a result the price you receive on your securities may be lower than the price at which we may repurchase the securities from such dealer.

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

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

• 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.

8 

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

• POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and as agent of the issuer for the offering of the securities, hedging our obligations under the securities and determining their estimated value. In performing these duties, the economic interests of us and our affiliates 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.

• 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 Trade Date may be less than the Price to Public.” Therefore, in addition to the level of the Underlying, the terms of the securities at issuance and the value of the securities 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 Underlying;

o the time to maturity of the securities;

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

o interest and yield rates in the market generally;

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

o events affecting companies engaged in the industry tracked by the Underlying;

o geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the components included in the Underlying or markets generally and which may affect the level of the Underlying; 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 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 UNDERLYING — Your return on the securities will not reflect the return you would realize if you actually owned shares of the Underlying or the assets that comprise the Underlying. The return on your investment is not the same as the total return based on the purchase of shares of the Underlying or the assets that comprise the Underlying.

• 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 shares of the Underlying or the assets that comprise the Underlying.

• ANTI-DILUTION PROTECTION IS LIMITED — The calculation agent will make anti-dilution adjustments for certain events affecting the Underlying. However, an adjustment will not be required in response to all events that could affect the Underlying. 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

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 securities may be used in connection with hedging our obligations under the securities through one or more of our affiliates. Such hedging or trading activities on or prior to the Trade Date and during the term of the securities (including on any calculation date, as defined in any accompanying product supplement) could adversely affect the value of the Underlying and, as a result, could decrease the amount you may receive on the securities 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.” The discussions below and in the accompanying product supplement do not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b) of the Internal Revenue Code.

In the opinion of our counsel, Davis Polk & Wardwell LLP, the securities should be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, as described in the section of the accompanying product supplement called “Material United States Federal Income Tax Considerations—U.S. Holders—Contingent Payment Debt Instruments,” and the remaining discussion assumes that this treatment of the securities is respected.

If you are a U.S. Holder, you will be required to recognize interest income during the term of the securities at the “comparable yield,” which generally is the yield at which we could issue a fixed-rate debt instrument with terms similar to those of the securities, including the level of subordination, term, timing of payments and general market conditions, but excluding any adjustments for the riskiness of the contingencies or the liquidity of the securities. We are required to construct a “projected payment schedule” in respect of the securities representing a payment the amount and timing of which would produce a yield to maturity on the securities equal to the comparable yield. Assuming you hold the securities until their maturity, the amount of interest you include in income based on the comparable yield in the taxable year in which the securities mature will be adjusted upward or downward to reflect the difference, if any, between the actual and projected payment on the securities at maturity as determined under the projected payment schedule.

Upon the sale, exchange or retirement of the securities prior to maturity, you generally will recognize gain or loss equal to the difference between the proceeds received and your adjusted tax basis in the securities. Your adjusted tax basis will equal your purchase price for the securities, increased by interest previously included in income on the securities. Any gain generally will be treated as ordinary income, and any loss generally will be treated as ordinary loss to the extent of prior interest inclusions on the security and as capital loss thereafter.

If the payment at maturity becomes fixed as a result of a Barrier Event that occurs more than six months prior to the maturity date, you will be required to account for the difference between the originally projected payment at maturity and the fixed payment in a reasonable manner over the remaining term of the securities. In addition, the character of any gain or loss recognized upon sale or exchange of the securities after any such Barrier Event will be affected. You should consult your tax advisor concerning the tax consequences of a Barrier Event.

We will determine the comparable yield for the securities and will provide that comparable yield, and the projected payment schedule, in the final pricing supplement for the securities.

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

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 securities, you generally will not be subject to U.S. federal withholding or income tax in respect of any amount paid to you with respect to the securities, provided that (i) income in respect of the securities 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. See “Material United States Federal Income Tax Considerations —Non-U.S. Holders Generally” in the accompanying product supplement for a more detailed discussion of the rules applicable to Non-U.S. Holders of the securities.

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 Internal Revenue Service (the “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

14 

Section 871(m) will be made as of the Trade 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.

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.

You should read the section entitled “Material United States Federal Income Tax Considerations” in the accompanying product supplement.

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.

Supplemental Plan of Distribution

Under the terms and subject to the conditions contained in a distributor accession confirmation with Incapital LLC dated March 23, 2012, Incapital LLC will act as placement agent for the securities. The placement agent will receive a fee from Credit Suisse or one of our affiliates that will not exceed $49 per $1,000 principal amount of the securities. The placement agent will forgo some or all discounts and commissions with respect to the sales of securities into certain fiduciary accounts. For additional information, see “Underwriting (Conflicts of Interest)” in the accompanying product supplement.

We expect to deliver the securities against payment for the securities on the Settlement Date indicated herein, which may be a date that is greater than two business days following the Trade 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 Trade Date, purchasers who wish to transact in the securities more than two business days prior to the Settlement Date will be required to specify alternative settlement arrangements to prevent a failed settlement.
