Investment Description

Linked to the SPDR^® S&P^®Biotech ETF

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 fund closing price on the relevant calculation day.

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 fund closing price on the calculation day for that quarter is greater than or equal to the threshold price. However, if the fund closing price on a calculation day is less than the threshold price, you will not receive any contingent coupon for the relevant quarter. If the closing level is less than the threshold level on every calculation day, you will not receive any contingent coupons throughout the entire term of the securities. The contingent coupon rate is 9.00% per annum

Automatic Call: If the fund closing price on any of the quarterly calculation days from October 2019 to January 2021, inclusive, is greater than or equal to the starting price, the securities will be automatically called for the original offering price plus a final contingent coupon

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 price is greater than or equal to the threshold price. If the ending price is less than the threshold price, you will lose more than 25%, and possibly all, of the original offering price of your securities

The threshold price is equal to 75% of the starting price

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

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 stated maturity

Credit Suisse currently estimates the value of each $1,000 principal amount of the securities on the pricing date is $969.15 (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.

The securities have complex features and investing in the securities involves risks not associated with an investment in conventional debt securities. See “Selected Risk Considerations” in this fact sheet and “Selected Risk Considerations” in the accompanying pricing supplement.

Investors should carefully review the accompanying pricing supplement, underlying supplement, product supplement, prospectus supplement and prospectus before making a decision to invest in the securities.

NOT A BANK DEPOSIT AND NOT INSURED OR GUARANTEED BY THE FDIC OR ANY OTHER GOVERNMENTAL AGENCY

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:

On each “contingent coupon payment date” (the third business day following each calculation day, subject to postponement as set forth in the accompanying pricing supplement), you will receive a contingent coupon at a per annum rate equal to the contingent coupon rate if, and only if, the fund closing price on the related calculation day is greater than or equal to the threshold price.

If the fund closing price on any calculation day is less than the threshold price, you will not receive any contingent coupon on the related contingent coupon payment date. If the fund closing price is less than the threshold price on all quarterly calculation days, you will not receive any contingent coupons over the term of the securities.

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

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

If the fund closing price on any of the quarterly calculation days from October 2019 to January 2021, inclusive, is greater than or equal to the starting price, 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. 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, 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 price is less than the threshold price, 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 coupons, if any. You will not participate in any appreciation of the Fund, but you will have full downside exposure to the Fund on the final calculation day if the ending price is less than the threshold price.

The following profile illustrates the potential payment at stated maturity on the securities (excluding the final contingent coupon, if any) for a range of hypothetical performances of the Fund on the final calculation day from the starting price to the ending price, 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 price on the final calculation day and whether you hold your securities to stated maturity.

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 on the call settlement date. In the event the securities are automatically called, your total return on the securities will equal any contingent coupons received prior to the call settlement date and the contingent coupon 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 ending prices of the Fund on the final calculation day, the hypothetical redemption amount payable at stated maturity per security (excluding the final contingent coupon, if any).

The above figures do not take into account contingent coupons, 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 coupons, 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 price on the final calculation day.

The risk factors listed below are discussed in detail in the “Selected Risk Considerations” section in the accompanying pricing supplement. Please review those risk disclosures carefully.
