Our Central Index Key, or CIK, on the SEC website is 1053092. As used in this pricing supplement, the “Company,” “we,” “us,” or “our” refers to Credit Suisse.

This pricing supplement, together with the documents listed above, contains the terms of the securities and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, fact sheets, correspondence, trade ideas, structures for implementation, sample structures, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in “Selected Risk Considerations” in this pricing supplement and “Risk Factors” in the accompanying product supplement, as the securities involve risks not associated with conventional debt securities. You should consult your investment, legal, tax, accounting and other advisors before deciding to invest in the securities.

Selected Risk Considerations

An investment in the securities involves significant risks. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement.

•

THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE — Although the return on the securities will be based on the Interest Rate, the payment of any amount due on the securities, including any applicable interest payments and the redemption amount, is subject to the credit risk of Credit Suisse. Investors are dependent on our ability to pay all amounts due on the securities and, therefore, investors are subject to our credit risk. 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.

•

CERTAIN BUILT-IN COSTS ARE LIKELY TO ADVERSELY AFFECT THE VALUE OF THE SECURITIES PRIOR TO MATURITY — While the payment at maturity described in this pricing supplement is based on the full principal amount of your securities, the original issue price of the securities includes the agent’s commission and the cost of hedging our obligations under the securities through one or more of our affiliates. As a result, the price, if any, at which Credit Suisse (or its affiliates), will be willing to purchase securities from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the Maturity Date could result in a substantial loss to you. The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity.

•

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 hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities.

•

MANY ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE SECURITIES — The value of the securities will be affected by a number of economic and market factors that may either offset or magnify each other, including:

the time to maturity of the securities;

changes in U.S. interest and swap rates;

interest and yield rates in the market generally;

investors’ expectations with respect to the rate of inflation;

geopolitical conditions and a variety of economic, financial, political, regulatory or judicial events that affect the interest and yield rates or markets generally; and

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.

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. For further information, please refer to “Supplemental Use of Proceeds and Hedging” in the accompanying product supplement.

Material United States Federal Income Tax Considerations

In the opinion of Davis Polk & Wardwell LLP, acting as special tax counsel, for U.S. federal income tax purposes, the securities will be treated as fixed rate debt instruments, and will not be treated as having original issue discount. Accordingly, interest paid on the securities should generally be taxable to you as ordinary interest income at the time it accrues or is received in accordance with your regular method of tax accounting for U.S. federal income tax purposes. See “Material United States Federal Income Tax Considerations—U.S. Holders—Fixed Rate Notes” in the accompanying product supplement.

Supplemental Plan of Distribution (Conflicts of Interest)

Under the terms and subject to the conditions contained in a distribution agreement with Incapital LLC dated March 23, 2012, which we refer to as the distribution agreement, Incapital LLC will act as placement agent for the securities. The placement agents will receive a fee from Credit Suisse or one of our affiliates that will not exceed $13.50 per $1,000 principal amount of the securities. For additional information, see “Underwriting (Conflicts of Interest)” in the accompanying product supplement.
