Investment description

Linked to the EURO STOXX 50^®Index

Unlike ordinary debt securities, the securities do not pay interest or repay a fixed amount of principal at stated maturity. Instead, the securities provide for a payment at stated maturity that may be greater than, equal to or less than the original offering price of the securities, depending on the performance of the Index from its starting level to its ending level.
The payment at stated maturity will reflect the following terms:

If the ending level is greater than the starting level:

You will receive the original offering price plus 200% participation in the upside performance of the Index, subject to a maximum total return at stated maturity of 60% to 65% (to be determined on the pricing date) over the original offering price

If the ending level is equal to or less than the starting level but equal to or greater than the threshold level:

You will be repaid the original offering price

If the ending level is less than the threshold level:

You will receive less than the original offering price and will have 1-to-1 downside exposure to the decrease in the level of the Index beyond the threshold level

Investors may lose up to 80% of the original offering price

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 periodic interest payments or dividends

No exchange listing; designed to be held to maturity

* To the extent that we make any change to the expected pricing date or expected issue date, the calculation day and stated maturity may also be changed at our discretion to ensure that the term of the securities remains the same.

Credit Suisse currently estimates the value of each $1,000 original offering price of the securities on the pricing date will be between $920 and $960 (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)). This range of estimated values reflects terms that are not yet fixed. A single estimated value reflecting final terms will be determined on the pricing date. See “Investment Description” and “Selected Risk Considerations” in the accompanying preliminary 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, “Selected Risk Considerations” in the accompanying preliminary pricing supplement and “Risk Factors” in the accompanying product supplement.

For purposes of the securities offered by the accompanying preliminary 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 preliminary pricing supplement, as set forth in the table below:

The risks set forth below are discussed in detail in the “Selected Risk Considerations” section in the accompanying preliminary pricing supplement and the “Risk Factors” section in the accompanying product supplement. Please review those risk disclosures carefully.

Assumes a hypothetical capped value of 162.50%, or $1,625 per security (the midpoint of the specified range of the capped value). 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. The actual amount you receive at stated maturity and the resulting rates of return will depend on the actual starting level, ending level and capped value.

The following profile is based on a hypothetical capped value of 162.50% or $1,625 per security (the midpoint of the specified range for the capped value), a participation rate of 200% and a threshold level equal to 80% of the starting level. This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual ending level, the actual capped value and whether you hold your securities to maturity.

If the ending level is less than the threshold level, you will receive less than the original offering price of your securities at stated maturity, and you may lose 80% of your investment.

You may revoke your offer to purchase the securities at any time prior to the time at which we accept such offer on the date the securities are priced. We reserve the right to change the terms of, or reject any offer to purchase the securities prior to their issuance. In the event of any changes to the terms of the securities, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.
