Product Terms

If the Final Level is greater than the Initial Level, you will participate in the leveraged appreciation, if any, of the Underlying.

If the Final Level is equal to or less than the Initial Level, you will receive the principal amount of the securities you hold at maturity.

Any payment on the securities is subject to our ability to pay our obligations as they become due.

The Underlying is designed to provide exposure to a hypothetical “balanced” portfolio while targeting a realized daily volatility of 5%. By “balanced” we mean the Underlying’s hypothetical portfolio may, under certain circumstances include both equity exposure, in the form of large-cap U.S. equities included in the Credit Suisse RavenPack AIS Index described in the accompanying underlying performance supplement and the accompanying underlying supplement; and fixed income exposure, in the form of U.S. Treasury note futures contracts tracked by the Fixed Income Indices described in the accompanying underlying performance supplement and the accompanying underlying supplement. “Balanced” does not imply any risk adjusted diversified asset class allocation or actual balance among asset classes. The Index Calculation Agent and Index Sponsor for the Underlying is an affiliate of ours. For more information on the Underlying, please see the underlying performance supplement and underlying supplement.

Fees:	Certain fiduciary accounts may pay a purchase price of at least $965 per $1,000 principal amount of securities. Credit Suisse Securities (USA) LLC and any agent (the “Agents”) may pay varying discounts and commissions of up to $35 per $1,000 principal amount of securities, of which $5 may be paid to certain institutions or service providers on securities not sold to certain fiduciary accounts in consideration for providing education, structuring or other services with respect to the distribution of the securities. CSSU or another broker or dealer will forgo some or all discounts and commissions with respect to the sales of securities into certain fiduciary accounts. The Agent(s) through whom we distribute securities may enter into arrangements with other institutions with respect to the distribution of the securities, and those institutions may share in the commissions, discounts or other compensation received by the Agent(s), may be compensated separately and may also receive commissions from purchasers for whom they may act as agents. In addition, an affiliate of ours will pay referral fees of $7.50 per $1,000 principal amount of securities. The Agent(s) 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.

Credit Suisse currently estimates the value of each $1,000 principal amount of the securities on the Trade Date will be between $920 and $950 (as determined by reference to its pricing models and the rate it is currently paying to borrow funds through issuance of the securities (its “internal funding rate”)). A single estimated value reflecting final terms will be determined on the Trade Date.
