Key Terms

Issuer:	Credit Suisse AG (“Credit Suisse”), acting through its London branch
Reference Share Issuer:	For each Underlying, the issuer of such Underlying.
Underlyings:	The securities are linked to the performance of the lowest performing of the Underlyings set forth in the table below. Each Underlying is identified in the table below, together with its Bloomberg ticker symbol, Initial Level and expected  Knock-In Level and Trigger Level (each level to be determined on the Trade Date):
	Underlying	Ticker	Initial Level	Knock-In Level	Trigger Level
	Common stock of Overstock.com, Inc.	OSTK UQ <Equity>		(Approximately 55% of Initial Level)	(100% of Initial Level)
	Class A common stock of Roku, Inc.	ROKU UW <Equity>		(Approximately 55% of Initial Level)	(100% of Initial Level)
Coupons:	If these securities have not been previously automatically redeemed, we will pay a coupon on each Coupon Payment Date in an amount expected to be $25 (equivalent to approximately 30.00% per annum) (to be determined on the Trade Date) per $1,000 principal amount of securities. If any Coupon Payment Date is not a business day, the coupon will be payable on the first following business day, unless that business day falls in the next calendar month, in which case payment will be made on the first preceding business day. The amount of any coupon will not be adjusted with respect to any postponement of a Coupon Payment Date and no interest or other payment will be payable hereon because of any such postponement of a Coupon Payment Date. No coupons will be payable following an Automatic Redemption. Coupons will be payable on the applicable Coupon Payment Date to the holder of record at the close of business on the business day immediately preceding the applicable Coupon Payment Date, provided that the coupon payable on the Automatic Redemption Date or Maturity Date, as applicable, will be payable to the person to whom the Automatic Redemption Amount or the Redemption Amount, as applicable, is payable.
Redemption Amount:	If these securities have not been previously automatically redeemed, at maturity, the Redemption Amount you will receive will depend on the individual performance of each Underlying and whether a Knock-In Event has occurred. For each $1,000 principal amount of securities, the cash or shares to be paid or delivered will be determined as follows:

	•	If a Knock-In Event has occurred, the Physical Delivery Amount plus a cash amount in respect of any fractional share, subject to our election to pay cash instead as noted below. If a Knock-In Event has occurred, you could receive the shares of the Lowest Performing Underlying with a value likely to be less than $550. You could lose your entire investment.
	•	If a Knock-In Event has not occurred, a cash payment equal to $1,000. Therefore, you will not participate in the appreciation of any Underlying.
	Any payment or delivery on the securities is subject to our ability to meet our obligations as they become due.
Physical Delivery Amount:	The Physical Delivery Amount per $1,000 principal amount of securities is a number of shares of the Lowest Performing Underlying rounded down to the nearest whole number and equal to the product of (i) $1,000 divided by the Initial Level of the Lowest Performing Underlying and (ii) the applicable share adjustment factor. Each share adjustment factor is initially set equal to 1.0 on the Trade Date, subject to adjustment as described under “Description of the Securities—Adjustments” in the relevant product supplement. In lieu of any fractional shares in respect of the Physical Delivery Amount we will pay a cash amount equal to such fractional share multiplied by the Final Level of the Lowest Performing Underlying. If the fractional share amount to be paid in cash is a de minimis amount, as determined by the calculation agent, the holder will not receive such amount. The Physical Delivery Amount (together with any cash amount paid in lieu of fractional shares) will be determined for each $1,000 principal amount of securities you hold. At our election, you may receive cash instead of the Physical Delivery Amount, in an amount equal to the product of (i) $1,000 divided by the Initial Level of the Lowest Performing Underlying and (ii) the Final Level of the Lowest Performing Underlying. If we exercise our option to deliver cash, we will give notice of our election at least one business day before the Valuation Date.

1

Automatic Redemption:	If a Trigger Event occurs, the securities will be automatically redeemed and you will receive a cash payment equal to $1,000 for each $1,000 principal amount of the securities (the “Automatic Redemption Amount”) and the coupon payable on the immediately following Coupon Payment Date. No further payments will be made in respect of the securities. Payment will be made with respect to such Automatic Redemption on the Coupon Payment Date immediately following the relevant Trigger Observation Date (the “Automatic Redemption Date”). Any payment or delivery on the securities is subject to our ability to meet our obligations as they become due.
Trigger Event:	A Trigger Event will occur if, on any Trigger Observation Date, the closing level of each Underlying on such Trigger Observation Date is equal to or greater than its respective Trigger Level.
Knock-In Event:	A Knock-In Event will occur if the Final Level of any Underlying is less than its Knock-In Level.
Lowest Performing Underlying:	The Underlying with the lowest Underlying Return.
Underlying Return:	For each Underlying, the lesser of (i) zero and (ii) an amount calculated as follows:
	Final Level − Initial Level Initial Level
Initial Level:	For each Underlying, the closing level of such Underlying on the Trade Date. In the event that the closing level for any Underlying is not available on the Trade Date, the Initial Level for such Underlying will be determined on the immediately following trading day on which a closing level is available.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.
Valuation Date:	March 26, 2020, subject to postponement as set forth in any accompanying product supplement under “Description of the Securities—Postponement of calculation dates.”
Maturity Date:	March 30, 2020, subject to postponement as set forth in any accompanying product supplement under “Description of the Securities—Postponement of calculation dates.” If the Maturity Date is not a business day, the Redemption Amount will be payable on the first following business day, unless that business day falls in the next calendar month, in which case payment will be made on the first preceding business day.
CUSIP:	22549JJ35

Hypothetical Redemption Amounts and Total Payments on the Securities

The table and examples below illustrate, for a $1,000 investment in the securities, hypothetical Redemption Amounts payable at maturity for a hypothetical range of Underlying Returns of the Lowest Performing Underlying. The table and examples below assume that (i) a coupon of $25 per $1,000 principal amount of securities will be paid on each Coupon Payment Date, (ii) the securities are not automatically redeemed prior to maturity, (iii) the term of the securities is exactly one year, (iv) the Knock-In Level for each Underlying is 55% of the Initial Level of such Underlying, (v) the Lowest Performing Underlying is the common stock of Overstock.com, Inc., (vi) the hypothetical Initial Level of the Lowest Performing Underlying is $18, (vii) a share adjustment factor of 1.0 and (viii) if the Physical Delivery Amount is to be delivered at maturity, we do not exercise our right to pay cash instead of the Physical Delivery Amount. The actual coupon amount and Knock-In Levels will be determined on the Trade Date. The examples are intended to illustrate hypothetical calculations of only the Redemption Amount and do not illustrate the calculation or payment of any individual coupon.

The hypothetical Redemption Amounts set forth below are for illustrative purposes only. The actual Redemption Amount applicable to a purchaser of the securities will depend on whether a Knock-In Event has occurred and on the Final Level of the Lowest Performing Underlying. It is not possible to predict whether a Knock-In Event will occur and, in the event that there is a Knock-In Event, by how much the level of the Lowest Performing Underlying has decreased from its Initial Level to its Final Level. Furthermore, it is not possible to predict whether a Trigger Event will occur. If a Trigger Event occurs, the securities will be automatically redeemed for a cash payment equal to the principal amount of the securities you hold and the coupon payable and no further payments will be made in respect of the securities.

You will not participate in any appreciation in the Underlyings. You should consider carefully whether the securities are suitable to your investment goals. Any payment or delivery on the securities is subject to our ability to meet our obligations as they become due. The numbers appearing in the table and examples below have been rounded for ease of analysis.

The total payment or delivery on the securities will be equal to the Redemption Amount applicable to an investor plus the total coupons on the securities.

The following examples illustrate how the Redemption Amount is calculated.

Example 1: A Knock-In Event has occurred because the Final Level of an Underlying is less than its Knock-In Level.

Underlying	Final Level
OSTK	40% of Initial Level
ROKU	110% of Initial Level

Since the Final Level of OSTK is less than its Knock-In Level, a Knock-In Event has occurred. OSTK is also the Lowest Performing Underlying. Therefore, the Redemption Amount will equal the Physical Delivery Amount, calculated as follows:

Physical Delivery Amount	=	$1,000/Initial Level of the Lowest Performing Underlying
	=	$1,000/$18
	=	55 shares of the Lowest Performing Underlying (55.5556 rounded down)
Redemption Amount	=	Physical Delivery Amount + cash in lieu of fractional shares equal to approximately 0.5556× $7.20
	=	55 shares of the Lowest Performing Underlying + $4

In this example, at maturity an investor would receive a Redemption Amount equal to 55 shares of the Lowest Performing Underlying and a cash payment of $4. The value of the Redemption Amount on the Valuation Date, which is the date on which the Final Level is determined, is $400, calculated as follows:

Physical Delivery Amount	=	55 shares of the Lowest Performing Underlying
Value of Redemption Amount	=	(55 shares of the Lowest Performing Underlying × $7.20) + $4
	=	$396 + $4
	=	$400

In these circumstances, the investor will be exposed to any depreciation in the level of the Lowest Performing Underlying from its Initial Level to the time of delivery.

Example 2: A Knock-In Event has not occurred because the Final Level of each Underlying is equal to or greater than its Knock-In Level; the Final Level of each Underlying is less than its Initial Level.

Underlying	Final Level
OSTK	80% of Initial Level
ROKU	95% of Initial Level

Even though the Final Level of each Underlying is below its Initial Level, since the Final Level of each Underlying is not less than its Knock-In Level, a Knock-In Event has not occurred.

Therefore, the Redemption Amount equals $1,000.

5

Example 3: A Knock-In Event has not occurred because the Final Level of each Underlying is equal to or greater than its Knock-In Level; the Final Level of each Underlying is greater than its Initial Level.

Underlying	Final Level
OSTK	105% of Initial Level
ROKU	110% of Initial Level

Since the Final Level of each Underlying is not less than its Knock-In Level, a Knock-In Event has not occurred. Even though the Final Level of each Underlying is above its Initial Level, you will not participate in any appreciation of the Underlyings.

Therefore, the Redemption Amount equals $1,000.

Selected Risk Considerations

An investment in the securities involves significant risks. Investing in the securities 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.

• YOU MAY RECEIVE LESS THAN THE PRINCIPAL AMOUNT AT MATURITY — If the securities are not automatically redeemed prior to the Maturity Date, you may receive less at maturity than you originally invested in the securities, or you may receive nothing, excluding coupons. If the Final Level of any Underlying is less than its Knock-In Level, you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, the Redemption Amount you will receive will be less than the principal amount of the securities, and you could lose your entire investment. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, by how much the level of the Lowest Performing Underlying has decreased from its Initial Level to its Final Level. Any payment or delivery on the securities is subject to our ability to meet our obligations as they become due.

• REGARDLESS OF THE AMOUNT OF ANY PAYMENT OR DELIVERY YOU RECEIVE ON THE SECURITIES, YOUR ACTUAL YIELD MAY BE DIFFERENT IN REAL VALUE TERMS — Inflation may cause the real value of any payment or delivery 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.

• MORE FAVORABLE TERMS TO YOU ARE GENERALLY ASSOCIATED WITH AN UNDERLYING WITH GREATER EXPECTED VOLATILITY AND THEREFORE CAN INDICATE A GREATER RISK OF LOSS — “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 Trade Date, the higher the expectation as of the Trade Date that the level of such Underlying could be less than its Knock-In Level on the Valuation Date, indicating a higher expected risk of loss on the securities. This greater expected risk will generally be reflected in a higher Coupon Rate than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as lower Knock-In Levels) than for similar securities linked to the performance of an Underlying with a lower expected volatility as of the Trade Date. You should therefore understand that a relatively higher Coupon Rate may indicate an increased risk of loss. Further, relatively lower Knock-In Levels may not necessarily indicate that the securities have a greater likelihood of a return of principal at maturity. The volatility of any Underlying can change significantly over the term of the securities. The levels of the Underlyings 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 Underlyings and the potential to lose a significant amount of your principal at maturity.

• AT MATURITY OR UPON AUTOMATIC REDEMPTION, THE SECURITIES WILL NOT PAY MORE THAN THE PRINCIPAL AMOUNT PLUS THE FINAL COUPON — At maturity or upon Automatic Redemption, the securities will not pay more than the principal amount plus the final coupon, regardless of the performance of any Underlying. Even if the Final Level of each Underlying is greater than its respective Initial Level, you will not participate in the appreciation of any Underlying. The maximum amount payable with respect to the securities (excluding coupons) is $1,000 for each $1,000 principal amount 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 maturity.

• THE SECURITIES ARE SUBJECT TO A POTENTIAL AUTOMATIC REDEMPTION, WHICH EXPOSES YOU TO REINVESTMENT RISK — If the securities are automatically redeemed prior to

7

the Maturity Date, you may be unable to invest in other securities with a similar level of risk that provide you with the opportunity to be paid the same coupons as the securities.

• AN AUTOMATIC REDEMPTION WOULD LIMIT YOUR OPPORTUNITY TO BE PAID COUPONS OVER THE FULL TERM OF THE SECURITIES — The securities are subject to a potential Automatic Redemption. If a Trigger Event occurs, the securities will be automatically redeemed and you will receive a cash payment equal to the principal amount of the securities you hold and the coupon payable on the immediately following Coupon Payment Date, and no further payments will be made with respect to the securities. In this case, you will lose the opportunity to continue to be paid coupons from the Automatic Redemption Date to the scheduled Maturity Date.

• THE VALUE OF THE PHYSICAL DELIVERY AMOUNT COULD BE LESS ON THE MATURITY DATE THAN ON THE VALUATION DATE — If a Knock-In Event has occurred, you will receive on the Maturity Date the Physical Delivery Amount, which will consist of a whole number of shares of the Lowest Performing Underlying plus an amount in cash corresponding to any fractional share, subject to our election to pay cash instead. The value of the Physical Delivery Amount on the Valuation Date will be less than $1,000 per $1,000 principal amount of securities and could fluctuate, possibly decreasing, in the period between the Valuation Date and the Maturity Date. We will make no adjustments to the Physical Delivery Amount to account for any such fluctuation and you will bear the risk of any decrease in the value of the Physical Delivery Amount between the Valuation Date and the Maturity Date.

• YOU WILL BE SUBJECT TO RISKS RELATING TO THE RELATIONSHIP BETWEEN THE UNDERLYINGS — The securities are linked to the individual performance of each Underlying. As such, the securities 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 the Final Level of the Lowest Performing Underlying is less than its Knock-In Level, 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 securities are linked increases the risk that the securities will perform poorly. By investing in the securities, you assume the risk that the Final Level of at least one of the Underlyings will be below its Knock-In 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 securities to perform poorly. However, if the Reference Share Issuers’ businesses tend to be related such that the performances of the Underlyings are correlated, then there is less likelihood that only one Underlying will cause the securities 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 Reference Share Issuer and its businesses, you are also taking a risk relating to the relationship between each Reference Share Issuer and Underlying to others.

• NO AFFILIATION WITH THE REFERENCE SHARE ISSUERS — We are not affiliated with the Reference Share Issuers. You should make your own investigation into the Underlyings and the Reference Share Issuers. In connection with the offering of the securities, neither we nor our affiliates have participated in the preparation of any publicly available documents or made any due diligence inquiry with respect to the Reference Share Issuers.

• HEDGING AND TRADING ACTIVITY — We or any of our affiliates may carry out hedging activities related to the securities, including in the Underlyings or instruments related to the Underlyings. We or our 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 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

8

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 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.

• 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. We and/or our affiliates may also currently or from time to time engage in business with the Reference Share Issuers, including extending loans to, or making equity investments in, the Reference Share Issuers or providing advisory services to the Reference Share Issuers. In addition, one or more of our affiliates may publish research reports or otherwise express opinions with respect to the Reference Share Issuers and these reports may or may not recommend that investors buy or hold shares of the Underlyings. As a prospective purchaser of the securities, you should undertake an independent investigation of the Reference Share Issuers that in your judgment is appropriate to make an informed decision with respect to an investment in the securities.

• 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 levels of any 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 Underlyings;

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

o the time to maturity of the securities;

o the dividend rate on the Underlyings;

o interest and yield rates in the market generally;

10

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

o events affecting companies engaged in the respective industries of the Reference Share Issuers;

o geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the Reference Share Issuers 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.

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.

• THE CLASS A COMMON STOCK OF ROKU, INC. HAS A LIMITED TRADING HISTORY — The Underlying began trading on the Nasdaq Global Select Market on September 28, 2017 and therefore has a limited historical performance. Past performance should not be considered indicative of future performance.

• NO OWNERSHIP RIGHTS IN THE UNDERLYINGS — Your return on the securities will not reflect the return you would realize if you actually owned shares of the Underlyings. The return on your investment is not the same as the total return based on a purchase of shares of the Underlyings.

• NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the securities, you will not have any ownership interest or rights in the Underlyings, such as voting rights or dividend payments. In addition, the issuer of the Underlyings will not have any obligation to consider your interests as a holder of the securities in taking any corporate action that might affect the value of the Underlyings and therefore, the value of the securities.

• 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 securities may be materially and adversely affected. See “Description of the Securities—Adjustments” in the relevant product supplement.

• 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.

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 Underlyings 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.

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 a put option (the “Put Option”) written by you with respect to the underlying shares, secured by a cash deposit equal to the stated principal amount of the security (the “Deposit”). 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 Trade Date.

Under this treatment:

· a portion of each coupon paid with respect to the securities will be attributable to interest on the Deposit; and

· the remainder will represent premium attributable to your grant of the Put Option (“Put Premium”).

We will specify in the final pricing supplement the portion of each coupon that we will allocate to interest on the Deposit and to Put Premium, respectively.

Assuming the treatment of a security as a Put Option and a Deposit is respected, amounts treated as interest on the Deposit should be taxed as ordinary interest income, while the Put Premium should not be taken into account prior to maturity or disposition of the securities.

Under this treatment, if you receive cash upon a redemption of the securities (including at maturity), you should recognize short-term capital gain in respect of the Put Option equal to the aggregate Put Premium previously received (including the Put Premium received upon redemption).  If you receive underlying shares at maturity of the securities, you should not recognize gain or loss with respect to the Put Option (other than in respect of cash received in lieu of a fractional share) but instead should have a tax basis in the underlying shares received (including any fractional share deemed received) equal to your tax basis in the securities minus the aggregate Put Premium previously received.  If you dispose of the securities prior to their maturity (or earlier redemption), you should recognize gain or loss with respect to the Put Option and the Deposit by allocating the amounts you receive on the disposition based on the fair market values of the Put Option and the Deposit at that time.  In the case of the Put Option, the aggregate amount of Put Premium previously received should be added to the amount received upon the disposition for purposes of calculating your gain or loss with respect to the Put Option.

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. For example, the entire coupon could be treated as ordinary income at the time received or accrued. Alternatively, 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.

This discussion does not address the U.S. federal tax consequences of the ownership or disposition of the underlying shares that you may receive at maturity. You should consult your tax advisor regarding the U.S. federal tax consequences of the ownership and disposition of the underlying shares.

Non-U.S. Holders. 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

15

United States Federal Income Tax Considerations—Non-U.S. Holders Generally—Substitute Dividend and Dividend Equivalent Payments,” in general, 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 to establish the Non-U.S. Holder’s status as a non-United States person. 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 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.

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.

Supplemental Plan of Distribution (Conflicts of Interest)

Under the terms and subject to the conditions contained in a distribution agreement dated May 7, 2007, as amended, which we refer to as the distribution agreement, we have agreed to sell the securities to CSSU. We may also agree to sell the securities to other agents that are parties to the distribution agreement. We refer to CSSU and other such agents as the “Agents.”

The distribution agreement provides that the Agents are obligated to purchase all of the securities if any are purchased.

The Agents may offer the securities at the offering price set forth on the cover page of this pricing supplement and may receive varying discounts and commissions of up to $28.75 per $1,000 principal amount of securities. The Agents may re-allow some or all of the discount on the principal amount per security on sales of such securities by other brokers or dealers. CSSU or another broker or dealer will forgo some or all discounts and commissions with respect to the sales of securities into certain fiduciary accounts. If all of the securities are not sold at the initial offering price, the Agents may change the public offering price and other selling terms.

An affiliate of Credit Suisse has paid or may pay in the future a fixed amount to broker-dealers in connection with the costs of implementing systems to support these securities.

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.

CSSU is our affiliate. In accordance with FINRA Rule 5121, CSSU may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer. A portion of the net proceeds from the sale of the securities will be used by CSSU or one of its affiliates in connection with hedging our obligations under the securities.

For further information, please refer to “Underwriting (Conflicts of Interest)” in any accompanying product supplement.
