Investment Description

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

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

Contingent Coupon: The securities will pay a contingent coupon on a quarterly basis until the earlier of stated maturity or automatic call if, and only if, the closing level of the lowest performing Index on the calculation day for that quarter is greater than or equal to its threshold level. However, if the closing level of the lowest performing Index on a calculation day is less than its threshold level, you will not receive any contingent coupon for the relevant quarter. The contingent coupon rate is 9.00% per annum

Automatic Call: If the closing level of the lowest performing Index on any of the quarterly calculation days from October 2017 to January 2019, inclusive, is greater than or equal to its starting level, the securities will be automatically called for the original offering price plus a final contingent coupon payment

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

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

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

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

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

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

Credit Suisse currently estimates the value of each $1,000 principal amount of the securities on the pricing date is $985.50 (as determined by reference to our pricing models and the rate we are currently paying to borrow funds through issuance of the securities (our internal funding rate)). See “Investment Description” and “Selected Risk Considerations” in the accompanying pricing supplement.

For purposes of the securities offered by the accompanying pricing supplement, all references to each of the following terms used in the accompanying product supplement will be deemed to refer to the corresponding term used in such pricing supplement, as set forth in the table below:

The lowest performing Index on any calculation day is the Index with the lowest performance factor on that calculation day.

The performance factor, with respect to an Index on any calculation day, will be its closing level on such calculation day divided by its starting level (expressed as a percentage).

On each contingent coupon payment date, you will receive a contingent coupon payment at a per annum rate equal to the contingent coupon rate if, and only if, the closing level of the lowest performing Index on the related calculation day is greater than or equal to its threshold level.

If the closing level of the lowest performing Index on any calculation day is less than its threshold level, you will not receive any contingent coupon payment on the related contingent coupon payment date. If the closing level of the lowest performing Index is less than its threshold level on all quarterly calculation days, you will not receive any contingent coupon payments over the term of the securities.

Each quarterly contingent coupon payment, if any, will be calculated per security as follows:

The contingent coupon rate is 9.00%per annum. Any contingent coupon payments will be rounded to the nearest cent, with one-half cent rounded upward.

If the closing level of the lowest performing Index on any of the quarterly calculation days from October 2017 to January 2019, inclusive, is greater than or equal to its starting level, the securities will be automatically called, and on the related call settlement date you will be entitled to receive a cash payment per security equal to the original offering price per security plus a final contingent coupon payment. The securities will not be subject to automatic call until the second quarterly calculation day, which is approximately six months after the issue date.

If the securities are automatically called, they will cease to be outstanding on the related call settlement date and you will have no further rights under the securities after such call settlement date.

If the securities are not automatically called prior to stated maturity, you will receive at stated maturity a payment per security equal to the redemption amount (in addition to the final contingent coupon payment, if any). The redemption amount per security will be determined as follows:

If the securities are not automatically called prior to stated maturity and the ending level of the lowest performing Index is less than its threshold level, you will lose more than 25%, and possibly all, of the original offering price of your securities at stated maturity.

Any return on the securities will be limited to the sum of your contingent coupon payments, if any. You will not participate in any appreciation of any Index, but you will have full downside exposure to the lowest performing Index on the final calculation day if the ending level of that Index is less than its threshold level.

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

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

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

The above figures do not take into account contingent coupon payments, if any, received during the term of the securities. As evidenced above, in no event will you have a positive rate of return based solely on the redemption amount received at maturity; any positive return will be based solely on the contingent coupon payments, if any, received during the term of the securities. Each security has an original offering price of $1,000.

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