Auto-Callable Contingent Income Securities due November 23, 2018
All Payments on the Securities Subject to the Coupon Barrier and Downside Threshold Features

Linked to the Performance of the Common Stock of Netflix, Inc. 

Principal at Risk Securities

Unlike ordinary debt securities, the Auto-Callable Contingent Income Securities due November 23, 2018 linked to the common stock of Netflix, Inc. (the “Underlying”), which we refer to as the securities, do not provide for the regular payment of interest or guarantee the return of any principal at maturity. Instead, the securities offer the opportunity for investors to earn a Contingent Coupon but only if the closing level of the Underlying on the applicable Observation Date is greater than or equal to 70% of the Initial Level, which we refer to as the Coupon Barrier Level. If the closing level of the Underlying is less than the Coupon Barrier Level on any Observation Date, you will not receive any Contingent Coupon for that period. As a result, investors must be willing to accept the risk of not receiving any Contingent Coupon during the entire term of the securities. In addition, if the closing level of the Underlying is greater than or equal to the Initial Level on any Observation Date scheduled to occur on or after February 20, 2018 (other than the Valuation Date), the securities will be automatically redeemed for an amount per security equal to the Principal Amount plus the Contingent Coupon payable on the immediately following Contingent Coupon Payment Date. At maturity, if the securities have not previously been automatically redeemed and the Final Level is greater than or equal to 70% of the Initial Level, which we refer to as the Downside Threshold Level, investors will receive the Principal Amount, and, because the Final Level is also greater than or equal to the Coupon Barrier Level, the Contingent Coupon with respect to the Valuation Date. However, if the Final Level is less than the Downside Threshold Level, investors will be fully exposed to the decline in the level of the Underlying over the term of the securities, and the Redemption Amount will be less than 70% of the Principal Amount of the securities and could be zero. Accordingly, investors may lose up to their entire initial investment in the securities. Investors will not participate in any appreciation of the Underlying. These securities are for investors who seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of losing a significant portion or all of their principal, the risk of receiving no Contingent Coupon on a Contingent Coupon Payment Date if the closing level of the Underlying is below the Coupon Barrier Level on the immediately preceding Observation Date, and the risk of an Automatic Redemption of the securities. 

All payments on the securities, including the repayment of principal, are subject to the credit risk of Credit Suisse.

Investment Summary

Auto-Callable Contingent Income Securities

Principal at Risk Securities

The Auto-Callable Contingent Income Securities due November 23, 2018 linked to the common stock of Netflix, Inc., which we refer to as the securities, provide an opportunity for investors to earn a Contingent Coupon at an annual rate of 12% (corresponding to $0.30 per period per security) but only if the closing level of the Underlying on the applicable Observation Date is greater than or equal to 70% of the Initial Level, which we refer to as the Coupon Barrier Level. It is possible that the closing level of the Underlying could remain below the Coupon Barrier Level for extended periods of time or even throughout the entire term of the securities so that you may receive few or no Contingent Coupons during the entire term of the securities. In addition, if the closing level of the Underlying is greater than or equal to the Initial Level on any Observation Date scheduled to occur on or after February 20, 2018 (other than the Valuation Date), the securities will be automatically redeemed for an amount per security equal to the Principal Amount plus the Contingent Coupon payable on the immediately following Contingent Coupon Payment Date.

If the securities have not been previously automatically redeemed and the Final Level is greater than or equal to 70% of the Initial Level, which we refer to as the Downside Threshold Level, the Redemption Amount will be the Principal Amount, and, because the Final Level is also greater than or equal to the Coupon Barrier Level, the Contingent Coupon with respect to the Valuation Date. However, if the Final Level is less than the Downside Threshold Level, investors will be fully exposed to the decline in the Underlying over the term of the securities and will receive an amount of cash that is significantly less than the Principal Amount, in proportion to the decline in the Underlying from the Initial Level to the Final Level. In this scenario, the value of any such payment will be less than 70% of the Principal Amount of the securities and could be zero. Investors in the securities must be willing to accept the risk of losing their entire principal and also the risk of not receiving any Contingent Coupons. In addition, investors will not participate in any appreciation of the Underlying.

Maturity:	Approximately one year, unless automatically redeemed earlier
Redemption Amount:	If the securities have not previously been automatically redeemed, investors will receive on the Maturity Date a Redemption Amount determined as follows: If the Final Level is greater than or equal to the Downside Threshold Level, investors will receive the Principal Amount, and, because the Final Level is also greater than or equal to the Coupon Barrier Level, the Contingent Coupon with respect to the Valuation Date. If the Final Level is less than the Downside Threshold Level, investors will receive a Redemption Amount that is less than 70% of the Principal Amount of the securities and could be zero. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment.
Contingent Coupons:	A Contingent Coupon at an annual rate of 12% (corresponding to $0.30 per period per security) will be paid on the securities on each Contingent Coupon Payment Date but only if the closing level of the Underlying is at or above the Coupon Barrier Level on the immediately preceding Observation Date. If, on any Observation Date, the closing level of the Underlying is less than the Coupon Barrier Level, we will pay no coupon for the applicable period.
Automatic Redemption:	If an Early Redemption Event occurs, the securities will be automatically redeemed and you will be entitled to receive a cash payment equal to the Principal Amount of the securities you hold and the Contingent Coupon payable on the immediately following Contingent Coupon Payment Date. No further payments will be made in respect of the securities following an Automatic Redemption. Payment will be made in respect of such Automatic Redemption on the Contingent Coupon Payment Date following the immediately preceding Observation Date. An Early Redemption Event will occur on any Observation Date scheduled to occur on or after February 20, 2018 (other than the Valuation Date) if the closing level of the Underlying on such Observation Date is equal to or greater than the Early Redemption

Key Investment Rationale

The securities do not guarantee any repayment of principal at maturity and offer investors an opportunity to earn a Contingent Coupon of 12% per annum but only if the closing level of the Underlying on the applicable Observation Date is greater than or equal to 70% of the Initial Level, which we refer to as the Coupon Barrier Level. The securities have been designed for investors who seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of (i) losing a significant portion or all of their principal, (ii) receiving no Contingent Coupon on a Contingent Coupon Payment Date if the level of the Underlying is below the Coupon Barrier Level on the immediately preceding Observation Date and (iii) an Automatic Redemption of the securities. The following scenarios are for illustrative purposes only to demonstrate how the Contingent Coupon and the Redemption Amount (if the securities have not previously been automatically redeemed) are calculated, and do not attempt to demonstrate every situation that may occur. Accordingly, the securities may or may not be automatically redeemed, the Contingent Coupon may be payable in none of, or some but not all of, the periods during the term of the securities and the Redemption Amount may be less than 70% of the Principal Amount of the securities and may be zero.

Scenario 1: The securities are automatically redeemed prior to maturity.	This scenario assumes that the securities are automatically redeemed prior to the Maturity Date on one of the Contingent Coupon Payment Dates for the Automatic Redemption Amount equal to the Principal Amount plus any Contingent Coupon otherwise due with respect to the immediately preceding Observation Date.  Prior to the Automatic Redemption, the Underlying may close at or above the Coupon Barrier Level on some or all of the Observation Dates.  In this scenario, investors receive the Contingent Coupon with respect to each Observation Date for which the Underlying closes at or above the Coupon Barrier Level, but not for the periods for which the Underlying closes below the Coupon Barrier Level on the related Observation Date. No further payments will be made on the securities once they have been automatically redeemed.
Scenario 2: The securities are not automatically redeemed prior to maturity, and investors receive principal back at maturity.	This scenario assumes that the securities are not automatically redeemed on any of the Contingent Coupon Payment Dates, and, as a result, investors hold the securities to maturity.  During the term of the securities, the Underlying may close at or above the Coupon Barrier Level on some Observation Dates and below the Coupon Barrier Level on the others.  Consequently, investors receive the Contingent Coupon for the periods for which the closing level of the Underlying is at or above the Coupon Barrier Level on the related Observation Date, but not for the periods for which the closing level of the Underlying is below the Coupon Barrier Level on the related Observation Date. On the Valuation Date, the Underlying closes at or above the Downside Threshold Level. Therefore, at maturity, investors will receive the Principal Amount, and, because the Final Level is greater than or equal to the Coupon Barrier Level, the Contingent Coupon with respect to the Valuation Date.
Scenario 3: The securities are not automatically redeemed prior to maturity, and investors suffer a substantial loss of principal at maturity.	This scenario assumes that the securities are not automatically redeemed on any of the Contingent Coupon Payment Dates, and, as a result, investors hold the securities to maturity. During the term of the securities, the Underlying closes below the Coupon Barrier Level on all or nearly all of the Observation Dates.  In this scenario, investors do not receive any Contingent Coupons, or receive Contingent Coupons for only a limited number of Contingent Coupon Payment Dates. On the Valuation Date, the Underlying closes below the Downside Threshold Level.  Therefore, investors receive an amount equal to the Principal Amount multiplied by the Underlying Return at maturity.  Under these circumstances, the Redemption Amount will be less than 70% of the Principal Amount and could be zero.  No coupon will be paid at maturity in this scenario.

Hypothetical Examples

The following hypothetical examples are for illustrative purposes only. Whether you receive a Contingent Coupon and whether an Early Redemption Event occurs will be determined on each Observation Date. If the securities are not automatically redeemed, the Redemption Amount will be determined by reference to the closing level of the Underlying on the Valuation Date. The actual Initial Level, Coupon Barrier Level, Downside Threshold Level and Early Redemption Level are set forth in “Key Terms” herein. All payments on the securities are subject to the credit risk of Credit Suisse. The numbers in the hypothetical examples may be rounded for ease of analysis. The below examples are based on the following terms:

Hypothetical Initial Level:	$200
Hypothetical Coupon Barrier Level:	$140, which is 70% of the hypothetical Initial Level
Hypothetical Downside Threshold Level:	$140, which is 70% of the hypothetical Initial Level
Hypothetical Early Redemption Level:	$200 which is 100% of the hypothetical Initial Level
Contingent Coupons:	12% per annum (corresponding to $0.30 per period per security) A Contingent Coupon is paid on each Contingent Coupon Payment Date but only if the closing level of the Underlying is at or above the Coupon Barrier Level on the related Observation Date.
Automatic Redemption:	If on any Observation Date scheduled to occur on or after February 20, 2018 (other than the Valuation Date) the closing level of the Underlying is greater than or equal to the Initial Level, the securities will be automatically redeemed for an Automatic Redemption Amount equal to the Principal Amount plus the Contingent Coupon payable on the immediately following Contingent Coupon Payment Date.
Redemption Amount (if the securities have not been automatically redeemed):	If the Final Level is greater than or equal to the Downside Threshold Level: the Principal Amount, and, because the Final Level is also greater than or equal to the Coupon Barrier Level, the Contingent Coupon with respect to the Valuation Date. If the Final Level is less than the Downside Threshold Level: (i) the Principal Amount multiplied by (ii) the Underlying Return.
Principal Amount:	$10

In Example 1, the securities are automatically redeemed on one of the Contingent Coupon Payment Dates, and no further payments are made on the securities after they have been automatically redeemed. In Examples 2, 3, and 4, the securities are not automatically redeemed prior to, and remain outstanding until, maturity.

Example 1 — The closing level of the Underlying is at or above the Early Redemption Level on the third Observation Date, but below the Early Redemption Level on the prior two Observation Dates, so the securities are automatically redeemed on the Contingent Coupon Payment Date immediately following the third Observation Date. The closing level of the Underlying is also at or above the Coupon Barrier Level on the two Observation Dates prior to (and excluding) the Observation Date immediately preceding the Automatic Redemption. Therefore, you would receive the Contingent Coupons with respect to those two Observation Dates, totaling $0.30 × 2 = $0.60. The closing level of the Underlying is greater than or equal to the Coupon Barrier Level on the Observation Date immediately preceding the third Contingent Coupon Payment Date. Upon Automatic Redemption, investors receive the Automatic Redemption Amount calculated as $10 + $0.30 = $10.30.

The total payment over the nine-month term of the securities is $0.60 + $10.30 = $10.90.

Example 2 — The closing level of the Underlying is below the Early Redemption Level on the three Observation Dates prior to the Valuation Date, so the securities are not automatically redeemed prior to maturity. The closing level of the Underlying is at or above the Coupon Barrier Level on all four Observation Dates including the Valuation Date, and the Final Level is above the Initial Level. Therefore, you would receive (i) the Contingent Coupons with respect to the three Observation Dates prior to (and excluding) the Valuation Date, totaling $0.30 × 3 = $0.90 and (ii) the Redemption Amount calculated as $10 + $0.30 = $10.30.

The total payment over the one-year term of the securities is $0.90 + $10.30 = $11.20.

This example illustrates the scenario where you receive a Contingent Coupon on every Contingent Coupon Payment Date throughout the term of the securities and receive your principal back at maturity, resulting in a 12% per annum interest rate over the term of the securities. Despite the fact that the Final Level is greater than the Initial Level, you will not participate in any appreciation of the Underlying. This is therefore the maximum amount payable over the term of the securities (including all potential Contingent Coupons). To the extent that coupons are not paid on every Contingent Coupon Payment Date, the effective interest rate on the securities will be less than 12% per annum and could be zero. If the securities are automatically

Principal at Risk Securities

redeemed prior to maturity, you will receive no more Contingent Coupon payments, may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

Example 3 — The closing level of the Underlying is below the Early Redemption Level on the three Observation Dates prior to the Valuation Date, so the securities are not automatically redeemed prior to maturity. The closing level of the Underlying is at or above the Coupon Barrier Level on two of the three Observation Dates prior to (and excluding) the Valuation Date. The Final Level is $160, which is above the Downside Threshold Level and Coupon Barrier Level. In this scenario, you receive a Redemption Amount equal to the Principal Amount and the Contingent Coupon with respect to the Valuation Date. Therefore, you would receive (i) the Contingent Coupons with respect to those two Observation Dates prior to (and excluding) the Valuation Date, totaling $0.30 × 2 = $0.60, but not for the other Observation Date prior to (and excluding) the Valuation Date, and (ii) the Redemption Amount calculated as $10 + $0.30 = $10.30.

The total payment over the one-year term of the securities is $0.60 + $10.30 = $10.90.

Example 4 — The closing level of the Underlying is below the Early Redemption Level on the three Observation Dates prior to the Valuation Date, so the securities are not automatically redeemed prior to maturity. The closing level of the Underlying is below the Coupon Barrier Level on all of the Observation Dates, and the Final Level is $80, which is below the Downside Threshold Level. Therefore, you would receive no Contingent Coupons, and the Redemption Amount would be calculated as $10 × $80 / $200 = $4.

The total payment over the one-year term of the securities is $0 + $4 = $4.

If the securities are not automatically redeemed prior to maturity and the Final Level is less than the Downside Threshold Level, you will lose a significant portion or all of your investment in the securities.

Selected Risk Considerations

This section describes the most significant risks relating to the securities. For a complete list of risk factors, please see any accompanying product supplement, prospectus and prospectus supplement. Investors should consult their financial and legal advisers as to the risks entailed by an investment in the securities and the suitability of the securities in light of their particular circumstances.

§ The securities do not guarantee the return of any principal. The terms of the securities differ from those of ordinary debt securities in that the securities do not guarantee the payment of regular interest or the return of any of the principal amount at maturity. Instead, if the securities have not automatically been redeemed prior to maturity and the Final Level is less than the Downside Threshold Level, you will be fully exposed to the decline in the Underlying over the term of the securities, and you will receive for each security that you hold at maturity an amount of cash that is significantly less than the Principal Amount, in proportion to the decline in the level of the Underlying from the Initial Level to the Final Level. Under this scenario, the value of any such payment will be less than 70% of the Principal Amount and could be zero. You may lose up to your entire initial investment in the securities. Any payment on the securities is subject to our ability to pay our obligations as they become due.

§ Regardless of the amount of any payment you receive on the securities, your actual yield may be different in real value terms. Inflation may cause the real value of any payment you receive on the securities to be less at maturity than it is at the time you invest. An investment in the securities also represents a forgone opportunity to invest in an alternative asset that generates a higher real return. You should carefully consider whether an investment that may result in a return that is lower than the return on alternative investments is appropriate for you.

§ The securities do not provide regular fixed interest payments. Unlike conventional debt securities, the securities do not provide for regular fixed interest payments. You will receive a Contingent Coupon with respect to a period only if the closing level of the Underlying on the related Observation Date is greater than or equal to the Coupon Barrier Level. If the closing level of the Underlying remains below the Coupon Barrier Level on each Observation Date over the term of the securities, you will not receive any Contingent Coupons. Thus, the securities are not a suitable investment for investors who require regular fixed income payments, since the number of Contingent Coupons is variable and may be zero.

In addition, if rates generally increase over the term of the securities, it is more likely that the Contingent Coupon, if any, could be less than the yield one might receive based on market rates at that time. This would have the further effect of decreasing the value of your securities both nominally in terms of below-market coupon payments and in real value terms. Furthermore, it is possible that you will not receive some or all of the Contingent Coupon payments over the term of the securities, and still lose your principal amount. Even if you do receive some or all of your principal amount at maturity, you will not be compensated for the time value of money. These securities are not short-term investments, so you should carefully consider these risks before investing.

§ More favorable terms to you are generally associated with an Underlying with greater expected volatility and therefore greater risk that you might lose some or all of your investment at maturity. “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 the Underlying could close below the Downside Threshold Level on the Valuation Date, indicating a higher expected risk of loss on the securities. The securities offer Contingent Coupon payments with the potential to result in a higher yield than the yield on our conventional debt securities of the same maturity. You should understand that, in exchange for this potentially higher yield, you will be exposed to significantly greater risks than investors in our conventional debt securities. These risks include (i) the risk that the number of Contingent Coupon payments you receive over the term of the securities, if any, will result in a below-market yield that is lower, and perhaps significantly lower, than the yield on our conventional debt securities of the same maturity and (ii) the risk that you might lose some or all of your principal amount at maturity if the Final Level is less than the Downside Threshold Level. The volatility of the Underlying is an important factor affecting these risks. Further, a relatively lower Downside Threshold Level may not necessarily indicate that the securities have a greater likelihood of a return of principal at maturity. Greater expected volatility of the Underlying as of the Trade Date may contribute to the higher yield potential, but would also represent a greater expected likelihood that you will receive only a few or no Contingent Coupon payments

Principal at Risk Securities

over the term of the securities and lose some or all of your principal at maturity. You should be willing to accept the downside market risk of the Underlying and the potential to lose a significant portion or all of your principal at maturity.

§ The securities are subject to a potential Automatic Redemption, which would limit your opportunity to be paid Contingent Coupons over the full term of the securities. The securities are subject to a potential Automatic Redemption. If an Early Redemption Event occurs, the securities will be automatically redeemed and you will be entitled to receive a cash payment equal to the Principal Amount of the securities you hold and the Contingent Coupon payable on that Contingent Coupon Payment Date, and no further payments will be made in respect of the securities. In this case, you will lose the opportunity to continue to be paid Contingent Coupons from the Automatic Redemption Date to the scheduled Maturity Date. If the securities are automatically redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that provide you with the opportunity to be paid the same coupons as the securities.

§ Investors will not participate in any appreciation in the level of the Underlying. Investors will not participate in any appreciation in the level of the Underlying from the Initial Level, and the return on the securities will be limited to the Contingent Coupons, if any, that are paid with respect to each Observation Date on which the closing level of the Underlying is greater than or equal to the Coupon Barrier Level until the securities are automatically redeemed or reach maturity. It is possible that the closing level of the Underlying could be below the Coupon Barrier Level on most or all of the Observation Dates so that you will receive few or no Contingent Coupons. If you do not earn sufficient Contingent Coupons over the term of the securities, the overall return on the securities may be less than the amount that would be paid on a conventional debt security of the issuer of comparable maturity.

§ The Contingent Coupon, if any, is paid on a periodic basis and is based solely on the closing level of the Underlying on the specified Observation Dates. Whether the Contingent Coupon will be paid with respect to an Observation Date will be based on the closing level of the Underlying on such date. As a result, you will not know whether you will receive the Contingent Coupon until near the end of the relevant period. Moreover, because the Contingent Coupon is based solely on the closing level of the Underlying on a specific Observation Date, if the closing level of the Underlying is less than the Coupon Barrier Level, you will not receive any Contingent Coupon with respect to such Observation Date, even if the closing level of the Underlying was higher on other days during the term of the securities.

§ At maturity or upon Automatic Redemption, the securities will not pay more than the Principal Amount, plus the final Contingent Coupon, if any. At maturity or upon Automatic Redemption, the securities will not pay more than the principal amount, plus the final Contingent Coupon, if any, regardless of the performance of the Underlying. Even if the Final Level is greater than the Initial Level, you will not participate in the appreciation of the Underlying. The maximum amount payable with respect to the securities (excluding any Contingent Coupons) is $10 for each $10 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.

§ No affiliation with the Reference Share Issuer. We are not affiliated with the Reference Share Issuer. You should make your own investigation into the Underlying and the Reference Share Issuer. 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 Issuer.

§ Hedging and trading activity. We, the dealer or any of our respective affiliates may carry out hedging activities related to the securities, including in the Underlying or instruments related to the Underlying. We, the dealer or our respective affiliates may also trade in the Underlying or instruments related to the Underlying from time to time. Any of these hedging or trading activities as of 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 is 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) is 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

Principal at Risk Securities

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 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

November 2017 Page 12

Auto-Callable Contingent Income Securities due November 23, 2018
All Payments on the Securities Subject to the Coupon Barrier and Downside Threshold Features  

Linked to the Performance of the Common Stock of Netflix, Inc.
Principal at Risk Securities

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. For instance, as calculation agent, Credit Suisse International will determine the Initial Level, the Coupon Barrier Level, and the Downside Threshold Level, whether you receive a Contingent Coupon on each Contingent Coupon Payment Date, whether you receive any previously unpaid Contingent Coupons and the Redemption Amount, if any. Moreover, certain determinations made by Credit Suisse International, in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor underlying or calculation of the closing level in the event of a market disruption event or discontinuance of the Underlying. These potentially subjective determinations may adversely affect the payout to you at maturity, if any. In addition, hedging activities by us or our affiliates on or prior to the Trade Date could potentially increase the Initial Level, and therefore, could increase the Coupon Barrier Level, which is the level at or above which the Underlying must close in order for you to receive a Contingent Coupon, and the Downside Threshold Level, which is the level at or above which the Underlying must close so that you are not exposed to the negative performance of the Underlying on the Valuation Date. 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 Issuer, including extending loans to, or making equity investments in, the Reference Share Issuer or providing advisory services to the Reference Share Issuer. In addition, one or more of our affiliates may publish research reports or otherwise express opinions with respect to the Reference Share Issuer and these reports may or may not recommend that investors buy or hold shares of the Underlying. As a prospective purchaser of the securities, you should undertake an independent investigation of the Reference Share Issuer 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 is 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 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 video tape rental industry;

o   geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the Reference Share Issuer 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 in the Underlying. Your return on the securities will not reflect the return you would realize if you actually owned shares of the Underlying. The return on your investment is not the same as the total return based on a purchase of the shares of the Underlying. For example, as a holder of the securities, you will not have any ownership interest or rights in the Underlying, such as voting rights or dividend payments. In addition, the issuer of the Underlying 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 Underlying 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 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 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 income tax consequences of the securities are not certain. There are no statutory provisions, regulations, published rulings, or judicial decisions addressing the characterization, for U.S. federal income tax purposes, of instruments with terms that are substantially the same as those of the securities.  No ruling from the U.S. Internal Revenue Service (the “IRS”) has been sought as to the U.S. federal income tax consequences of the ownership and disposition of the securities, and the tax treatment described under “Material U.S. Federal Income Tax Considerations” is not binding on the IRS or any court. Thus, the U.S. federal income tax consequences of the securities are not certain. 

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.

Material U.S. Federal Income Tax Considerations

The following discussion summarizes material U.S. federal income tax consequences of owning and disposing of the securities that may be relevant to holders of the securities that acquire their securities from us as part of the original issuance of the securities. This discussion applies only to holders that hold their securities as capital assets within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”). Further, this discussion does not address all of the U.S. federal income tax consequences that may be relevant to you in light of your individual circumstances or if you are subject to special rules, such as if you are:

· a financial institution,

· a mutual fund,

· a tax-exempt organization,

· a grantor trust,

· certain U.S. expatriates,

· an insurance company,

· a dealer or trader in securities or foreign currencies,

· a person (including traders in securities) using a mark-to-market method of accounting,

· a person who holds the securities as a hedge or as part of a straddle with another position, constructive sale, conversion transaction or other integrated transaction,

· a person whose functional currency is not the U.S. dollar, or

· an entity that is treated as a partnership for U.S. federal income tax purposes.

The discussion is based upon the Code, law, regulations, rulings and decisions, in each case, as available and in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. Tax consequences under state, local and foreign laws are not addressed herein. No ruling from the U.S. Internal Revenue Service (the “IRS”) has been sought as to the U.S. federal income tax consequences of the ownership and disposition of the securities, and the following discussion is not binding on the IRS.

You should consult your tax advisor as to the specific tax consequences to you of owning and disposing of the securities, including the application of federal, state, local and foreign income and other tax laws based on your particular facts and circumstances.

Characterization of the Securities

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of the securities or instruments with terms that are substantially the same as those of your securities. We cannot assure you that the IRS or any court will agree with the tax treatment described below. Possible alternative characterizations and risks to investors of such characterizations are discussed below.

Due to the terms of the securities and the uncertainty of the tax law with respect to the characterization of the securities, our special tax counsel, Orrick, Herrington & Sutcliffe LLP, believes that it is reasonable to treat the securities, for U.S. federal income tax purposes, as prepaid financial contracts with respect to the Underlying that are eligible for open transaction treatment in part, but is unable to opine that this characterization is more likely than not to be upheld. In the absence of an administrative or judicial ruling to the contrary, we intend to treat the securities and, by acceptance of the securities, you agree to treat the securities for all tax purposes in accordance with such characterization and the balance of this discussion assumes that the securities will be so treated.

Alternative Characterizations of the Securities

You should be aware that the characterization of the securities as described above is not certain, nor is it binding on the IRS or the courts. Thus, it is possible that the IRS would seek to characterize your securities in a manner that results in tax consequences to you that are different from those described below. For example, the IRS might characterize a security as a notional principal contract (an “NPC”). In general, payments on an NPC are accrued ratably (as ordinary income or deduction, as the case may be) over the period to which they relate regardless of an investor’s usual method of tax accounting. Payments made to terminate an NPC (other than perhaps a final scheduled payment) are capital in nature. Deductions for NPC payments may be limited in certain cases. Certain payments under an NPC may be treated as U.S. source income. Generally, the securities are not, and we do not expect that the securities will be, listed on a securities exchange. In the event the securities are listed on a securities exchange and the IRS seeks to characterize your securities as options, the securities would be characterized as Code section 1256 contracts. In such case, the securities would be

Principal at Risk Securities

marked-to-market at the end of the year and 40% of any gain or loss would be treated as short-term capital gain or loss, and the remaining 60% of any gain or loss would be treated as long-term capital gain or loss. It is also possible that the IRS would assert that the securities are debt instruments, which may result in adverse tax consequences. You should consult your tax advisor regarding the possible tax consequences of characterization of the securities as debt instruments. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the securities for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of your securities for U.S. federal income tax purposes.

U.S. Holders

For purposes of this discussion, the term “U.S. Holder,” for U.S. federal income tax purposes, means a beneficial owner of securities that is (1) a citizen or resident of the United States, (2) a corporation (or an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust, if (a) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has in effect a valid election to be treated as a domestic trust for U.S. federal income tax purposes. If a partnership (or an entity treated as a partnership for U.S. federal income tax purposes) holds securities, the U.S. federal income tax treatment of such partnership and a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership, or a partner of a partnership, holding securities, you should consult your tax advisor regarding the tax consequences to you from the partnership’s purchase, ownership and disposition of the securities.

In accordance with the agreed-upon tax treatment described above, a U.S. Holder will treat any coupon payment received in respect of a security as ordinary income includible in such U.S. Holder’s income in accordance with the U.S. Holder’s method of accounting. Upon the redemption, sale or other taxable disposition of a security, a U.S. Holder generally will recognize gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. Holder’s tax basis in the security. Such gain or loss will be long-term capital gain or loss in the case of a U.S. Holder that has held the security for more than one year at the time of disposition and short-term capital gain or loss otherwise. It is possible that a portion of the amount realized from the sale or taxable disposition of the securities prior to the payment date attributable to an expected coupon could be treated as ordinary income. You should consult your tax advisor regarding this possibility and the consequences of such treatment to you.

Medicare Tax

Certain U.S. Holders that are individuals, estates, and trusts must pay a 3.8% tax (the “Medicare Tax”) on the lesser of the U.S. Holder’s (1) “net investment income” or “undistributed net investment income” in the case of an estate or trust and (2) the excess of modified adjusted gross income over a certain specified threshold for the taxable year. “Net investment income” generally includes income from interest, dividends, and net gains from the disposition of property (such as the securities) unless such income or net gains are derived in the ordinary course of a trade or business (other than a trade or business that is a passive activity with respect to the taxpayer or a trade or business of trading in financial instruments or commodities). Net investment income may be reduced by allowable deductions properly allocable to such gross income or net gain. Any interest earned or deemed earned on the securities and any gain on sale or other taxable disposition of the securities will be subject to the Medicare Tax. If you are an individual, estate, or trust, you should consult with your tax advisor regarding application of the Medicare Tax to your income and gains in respect of your investment in the securities.

Securities Held Through Foreign Entities

Under certain provisions of the “Hiring Incentives to Restore Employment Act,” generally referred to as “FATCA,” and regulations thereunder, a 30% withholding tax is imposed on “withholdable payments” and certain “passthru payments” made to “foreign financial institutions” (as defined in the regulations or an applicable intergovernmental agreement) (and their more than 50% affiliates) unless the payee foreign financial institution agrees, among other things, to disclose the identity of any U.S. individual with an account at the institution (or the institution’s affiliates) and to annually report certain information about such account. The term “withholdable payments” generally includes (1) payments of fixed or determinable annual or periodical gains, profits, and income (“FDAP”), in each case, from sources within the United States, and (2) gross proceeds from the sale of any property of a type which can produce interest or dividends from sources within the United States. “Passthru payments” means any withholdable payment and any foreign passthru payment. To avoid becoming subject to the 30% withholding tax on payments to it, a financial institution may be required to report information to the IRS regarding the holders of the securities. In the case of holders who (i) fail to provide the relevant information, (ii) are foreign financial institutions who have not agreed to comply with these information reporting requirements, or (iii) hold the securities

directly or indirectly through such non-compliant foreign financial institutions, a payor may be required to withhold on a portion of payments under the securities. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or certify that they do not have any substantial U.S. owners) to withhold tax at a rate of 30%. If payments on the securities are determined to be from sources within the United States, such payments will be treated as withholdable payments for these purposes.

Withholding under FATCA will apply to all withholdable payments and certain passthru payments without regard to whether the beneficial owner of the payment is a U.S. person, or would otherwise be entitled to an exemption from the imposition of withholding tax pursuant to an applicable tax treaty with the United States or pursuant to U.S. domestic law. Unless a foreign financial institution is the beneficial owner of a payment, it will be subject to refund or credit in accordance with the same procedures and limitations applicable to other taxes withheld on FDAP payments provided that the beneficial owner of the payment furnishes such information as the IRS determines is necessary to determine whether such beneficial owner is a U.S.-owned foreign entity and the identity of any substantial U.S. owners of such entity. If such withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld.

Subject to the exceptions described below, FATCA’s withholding regime generally will apply to (i) withholdable payments (other than gross proceeds of the type described above and certain payments made with respect to a “preexisting obligation,” as defined in the regulations), (ii) payments of gross proceeds of the type described above with respect to a sale or disposition occurring after December 31, 2018, and (iii) foreign passthru payments made after the later of December 31, 2018, or the date that final regulations defining the term “foreign passthru payment” are published. Notwithstanding the foregoing, the provisions of FATCA discussed above generally will not apply to (a) with respect to foreign passthru payments, any obligation (other than an instrument that is treated as equity for U.S. tax purposes or that lacks a stated expiration or term) that is executed on or prior to the date that is six months after the date on which final regulations defining foreign passthru payments are published (a “grandfathered obligation”), (b) any obligation that produces withholdable payments solely because the obligation is treated as giving rise to a dividend equivalent pursuant to Code section 871(m) and the regulations thereunder that is executed on or prior to the date that is six months after the date on which obligations of its type are first treated as giving rise to dividend equivalents, and (c) any agreement requiring a secured party to make payments with respect to collateral securing one or more grandfathered obligations (even if the collateral is not itself a grandfathered obligation). Thus, if you hold your securities through a foreign financial institution or foreign entity, a portion of any of your payments may be subject to 30% withholding.

Information Reporting Regarding Specified Foreign Financial Assets

The Code and regulations thereunder generally require individual U.S. Holders (“specified individuals”) and “specified domestic entities” with an interest in any “specified foreign financial asset” to file an annual report on IRS Form 8938 with information relating to the asset, including the maximum value thereof, for any taxable year in which the aggregate value of all such assets exceeds $50,000 on the last day of the taxable year or $75,000 at any time during the taxable year. Certain individuals are permitted to have an interest in a higher aggregate value of such assets before being required to file a report. Specified foreign financial assets include, with some limited exceptions, any financial account maintained at a foreign financial institution and any debt or equity interest in a foreign financial institution, including a financial institution organized under the laws of a U.S. possession, and any of the following that are held for investment and not held in an account maintained by a financial institution: (1) any stock or security issued by a person other than a U.S. person (including a person organized in a U.S. possession), (2) any financial instrument or contract that has an issuer or counterparty that is other than a U.S. person (including a person organized in a U.S. possession), and (3) any interest in a foreign entity. Additionally, the regulations provide that specified foreign financial assets include certain retirement and pension accounts and non-retirement savings accounts.

Pursuant to the regulations and subject to certain exceptions, “specified domestic entities” are domestic corporations, domestic partnerships, or certain trusts that are formed or used for the purposes of holding, directly or indirectly, specified foreign financial assets. Generally, specified domestic entities are certain corporations and partnerships, which are closely held by a specified individual and that meet passive income or passive asset tests, and, with certain exceptions, domestic trusts that have one or more specified individuals or specified domestic entities as a current beneficiary.

Depending on the aggregate value of your investment in specified foreign financial assets, you may be obligated to file an IRS Form 8938 under this provision if you are an individual U.S. Holder or a specified domestic entity. Penalties apply to any failure to file IRS Form 8938. In the event a U.S. Holder (either a specified individual or specified domestic entity) does not file such form, the statute of limitations on the assessment and collection of U.S. federal income taxes of such U.S. Holder for the related tax year may not close before the date which is three years after the date such information is filed. You should consult your tax advisor as to the possible application to you of this information reporting requirement and the related statute of limitations tolling provision.

Non-U.S. Holders Generally

The U.S. federal income tax treatment of the coupon payments is unclear. Except as provided under “Securities Held Through Foreign Entities” and “Substitute Dividend and Dividend Equivalent Payments,” we currently do not intend to withhold any tax on any coupon payments made to a holder of the securities that is not a U.S. Holder (a “Non-U.S. Holder”) and that has no connection with the United States other than holding its securities, provided that such Non-U.S. Holder complies with applicable certification requirements. However, it is possible that the IRS could assert that such payments are subject to U.S. withholding tax, or that we or another withholding agent may otherwise determine that withholding is required, in which case we or the other withholding agent may withhold up to 30% on such payments (subject to reduction or elimination of such withholding tax pursuant to an applicable income tax treaty). We will not pay any additional amounts in respect of such withholding.

Except as provided under “Securities Held Through Foreign Entities” and “Substitute Dividend and Dividend Equivalent Payments,” payment of the redemption amount by us in respect to the securities (except to the extent of the coupons) to a Non-U.S. Holder that has no connection with the United States other than holding its securities will not be subject to U.S. withholding tax, provided that such Non-U.S. Holder complies with applicable certification requirements. Any gain realized upon the sale or other disposition of the securities by a Non-U.S. Holder generally will not be subject to U.S. federal income tax unless (1) such gain is effectively connected with a U.S. trade or business of such Non-U.S. Holder or (2) in the case of an individual, such individual is present in the United States for 183 days or more in the taxable year of the sale or other disposition and certain other conditions are met. Any effectively connected gains described in clause (1) above realized by a Non-U.S. Holder that is, or is taxable as, a corporation for U.S. federal income tax purposes may also, under certain circumstances, be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

Non-U.S. Holders that are subject to U.S. federal income taxation on a net income basis with respect to their investment in the securities should refer to the discussion above relating to U.S. Holders.

Substitute Dividend and Dividend Equivalent Payments

The Code and regulations thereunder treat a “dividend equivalent” payment as a dividend from sources within the United States. Unless reduced by an applicable tax treaty with the United States, such payments generally will be subject to U.S. withholding tax at a rate of 30%. A “dividend equivalent” payment is defined under the Code as (i) a substitute dividend payment made pursuant to a securities lending or a sale-repurchase transaction that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, (ii) a payment made pursuant to a “specified notional principal contract” (a “specified NPC”) that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, and (iii) any other payment determined by the IRS to be substantially similar to a payment described in the preceding clauses (i) and (ii).

Regulations provide that a dividend equivalent is any payment that references the payment or deemed payment of (i) a dividend from an underlying security pursuant to a securities lending or sale-repurchase transaction, (ii) a dividend from an underlying security pursuant to a specified NPC, (iii) a dividend from an underlying security pursuant to a specified equity-linked instrument (a “specified ELI”), and (iv) any other substantially similar payment. The regulations provide that a payment includes a dividend equivalent payment whether there is an explicit or implicit reference to a dividend with respect to the underlying security. An underlying security is any interest in an entity if a payment with respect to that interest could give rise to a U.S. source dividend pursuant to Treasury regulation section 1.861-3. An NPC is a notional principal contract as defined in Treasury regulation section 1.446-3(c). An equity-linked instrument (“ELI”) is a financial instrument (other than a securities lending or sale-repurchase transaction or an NPC) that references the value of one or more underlying securities, including a futures contract, forward contract, option, debt instrument, or other contractual arrangement. A “section 871(m) transaction” is any securities lending or sale-repurchase transaction, specified NPC, or specified ELI.

Pursuant to the regulations and Notice 2017-42, for any payment made on or after January 1, 2017 with respect to any transaction issued on or after January 1, 2017, any NPC or ELI that has a delta of one with respect to an underlying security when the NPC or ELI is issued is a specified NPC or specified ELI, respectively. For any payment made on or after January 1, 2019 with respect to any transaction issued on or after January 1, 2019, (a) a “simple” NPC or “simple” ELI that has a delta of 0.8 or greater with respect to an underlying security when the NPC or ELI is issued is a specified NPC or specified ELI, respectively, and (b) a “complex” NPC or “complex” ELI that meets a substantial equivalence test with respect to an underlying security at the time of issuance is a specified NPC or specified ELI, respectively.

Certain events could cause previously issued securities to be deemed to be issued as new securities for purposes of the effective dates provided in the regulations. For example, it is possible that the IRS could assert that a reconstitution or rebalancing of the Underlying is a significant modification of the securities due to an exercise of discretion with respect to such reconstitution or rebalancing and,

therefore, a deemed issuance of the securities upon the occurrence of such event. It is also possible that U.S. withholding tax could apply to the securities under these rules if a Non-U.S. Holder enters, or has entered, into certain other transactions in respect of the Underlying or the securities. A Non-U.S. Holder that enters, or has entered, into other transactions in respect of the Underlying or the securities should consult its own tax advisor regarding the application of Code section 871(m) to its securities in the context of its other transactions.

Withholding on payments will be based on actual dividends or, if otherwise notified by us in accordance with applicable regulations, on estimated dividends used in pricing the security. If an adjustment is made for the actual dividends, then the true-up payment (in addition to the estimated dividend) is added to the per-share dividend amount. If a transaction is a section 871(m) transaction, information regarding the amount of each dividend equivalent, the delta of the potential 871(m) transaction, the amount of any tax withheld and deposited, the estimated dividend amount and any other information necessary to apply the regulations will be provided, communicated, or made available to Non-U.S. Holders in a manner permitted by the applicable regulations.

In accordance with the regulations and Notice 2017-42, U.S. tax will be withheld on any portion of a payment or deemed payment (including, if appropriate, the payment of the purchase price) that is a dividend equivalent with respect to any security issued (or deemed issued) on or after January 1, 2017 and prior to January 1, 2019 that has a delta of one unless reduced by an applicable tax treaty and a properly executed IRS Form W-8 (or other qualifying documentation) is provided. Based on the terms of the securities and representations provided by us, our counsel is of the opinion that the securities (exclusive of any other transactions that may be combined with the securities as discussed herein) should not be treated as “delta-one transactions” with respect to an underlying security within the meaning of the regulations and, as a result, we do not intend to treat the securities as section 871(m) transactions. If withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld. These regulations are extremely complex. Non-U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them of these regulations and whether payments or deemed payments on the securities constitute dividend equivalent payments.

U.S. Federal Estate Tax Treatment of Non-U.S. Holders

A security may be subject to U.S. federal estate tax if an individual Non-U.S. Holder holds the security at the time of his or her death. The gross estate of a Non-U.S. Holder domiciled outside the United States includes only property situated in the United States. Individual Non-U.S. Holders should consult their tax advisors regarding the U.S. federal estate tax consequences of holding the securities at death.

Potential Changes to the Tax Rules for Financial Instruments

Members of Congress have from time to time proposed legislation relating to financial instruments, including legislation that would require holders to annually mark to market affected financial instruments (potentially including the securities). These or other potential changes in law could adversely affect the tax treatment of the securities and may be applied with retroactive effect. You are urged to consult your tax advisor regarding how any such potential changes in law could affect you.

Backup Withholding and Information Reporting

A holder of the securities (whether a U.S. Holder or a Non-U.S. Holder) may be subject to backup withholding with respect to certain amounts paid to such holder unless it provides a correct taxpayer identification number, complies with certain certification procedures establishing that it is not a U.S. Holder or establishes proof of another applicable exemption, and otherwise complies with applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. You can claim a credit against your U.S. federal income tax liability for amounts withheld under the backup withholding rules, and amounts in excess of your liability are refundable if you provide the required information to the IRS in a timely fashion. A holder of the securities may also be subject to information reporting to the IRS with respect to certain amounts paid to such holder unless it (1) is a Non-U.S. Holder and provides a properly executed IRS Form W-8 (or other qualifying documentation) or (2) otherwise establishes a basis for exemption. If such withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld.

Supplemental Plan of Distribution

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

CSSU will offer the securities at the offering price set forth on the cover page of this pricing supplement and will receive discounts and commissions of $0.175 per $10 principal amount of securities. MSSB and its financial advisors will collectively receive from CSSU discounts and commissions of $0.175 for each security they sell, of which $0.05 per $10 principal amount of securities reflects a structuring fee. CSSU 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. If all of the securities are not sold at the initial offering price, CSSU 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.

The agent for this offering, 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.

Validity of the Securities

In the opinion of Davis Polk & Wardwell LLP, as United States counsel to Credit Suisse, when the securities offered by this pricing supplement have been executed and issued by Credit Suisse and authenticated by the trustee pursuant to the indenture, and delivered against payment therefor, such securities will be valid and binding obligations of Credit Suisse, enforceable against Credit Suisse in accordance with their terms, subject to (i) applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, (ii) possible judicial or regulatory actions giving effect to governmental actions or foreign laws affecting creditors’ rights and (iii) concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith), provided that such counsel expresses no opinion as to the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above. This opinion is given as of the date of this pricing supplement and is limited to the laws of the State of New York, except that such counsel expresses no opinion as to the application of state securities or Blue Sky laws to the securities. Insofar as this opinion involves matters governed by Swiss law, Davis Polk & Wardwell LLP has relied, without independent inquiry or investigation, on the opinion of Homburger AG, dated July 31, 2017 and filed by Credit Suisse as an exhibit to a Current Report on Form 6-K on July 31, 2017. The opinion of Davis Polk & Wardwell LLP is subject to the same assumptions, qualifications and limitations with respect to such matters as are contained in the opinion of Homburger AG. In addition, the opinion of Davis Polk & Wardwell LLP is subject to customary assumptions about the establishment of the terms of the securities, the trustee’s authorization, execution and delivery of the indenture and its authentication of the securities, and the validity, binding nature and enforceability of the indenture with respect to the trustee, all as stated in the opinion of Davis Polk & Wardwell LLP dated July 31, 2017, which was filed by Credit Suisse as an exhibit to a Current Report on Form 6-K on July 31, 2017. Davis Polk & Wardwell LLP expresses no opinion as to waivers of objections to venue, the subject matter or personal jurisdiction of a United States federal court or the effectiveness of service of process other than in accordance with applicable law. In addition, such counsel notes that the enforceability in the United States of Section 10.08(c) of the indenture is subject to the limitations set forth in the United States Foreign Sovereign Immunities Act of 1976.
