ETRACS Crude Oil Shares Covered Call ETN

Key Considerations

Selected risk considerations:

An investment in the ETRACS ETNs involves risks. Selected risks are summarized here, but we urge you to read the more detailed explanation of risks described in the "Risk Factors" section of the prospectus supplement for the ETRACS ETNs (the "ETRACS Prospectus"). Capitalized terms used below but not defined herein shall have the meanings attributed to them in the ETRACS Prospectus.

• Market Risk — The ETNs are fully exposed to any decline in the Index. The level of the Index will be reduced by the cost of implementing the Index methodology, which will reduce both the value of and your return on the ETNs. Such reduction may be significant. The value of the Index used to calculate the payment at maturity or upon early redemption or acceleration will be reduced by the Notional Transaction Costs incurred in connection with the implementation of the covered call strategy of the Index. The Notional Transaction Costs reflect the monthly transaction costs of hypothetically buying and selling the call options and selling the Reference Oil Shares and equal 0.03%, 0.03% and 0.01%, respectively, times the closing price of the Reference Oil Shares on the date of such notional transactions and, which, on an annual basis, are expected to be approximately equal to 0.84%. The actual cost will vary depending on the value of the Reference Oil Shares on the date of such transactions. In addition, the Daily Investor Fee, based on an annual Investor Fee Rate of 0.85%, reduces the indicative value of the ETNs and the amount of your payment at maturity or upon early redemption or acceleration. The amount of your payment upon early redemption is further reduced by the Early Redemption Charge. If the level of the Index decreases or does not increase sufficiently to offset the impact of the Daily Investor Fee, and the Early Redemption Charge, if applicable, you will receive less, and possibly significantly less, than the initial amount of your investment in the ETNs.
• Variable Coupons — The monthly coupon amounts (if any) are variable and dependent on the premium generated by the notional sale of options on the Reference Oil Shares. You will not receive any fixed periodic interest payments on the ETNs. Any coupon amount is uncertain and could be zero.
• Credit Risk — Although the return on the ETNs will be based on the performance of the price return version of the Index, the payment of any amount due on the ETNs, including any payment at maturity or upon early redemption or acceleration, and payment of coupon amounts, if any, are subject to the credit risk of Credit Suisse. Investors are dependent on Credit Suisse’s ability to pay all amounts due on the ETNs, 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 market value of the ETNs prior to maturity.
• Strategy Risk — Unfavorable price movements in the Reference Oil Shares or the options on the Reference Oil Shares may cause negative performance of the Index and loss of your investment, and there is no assurance that the strategy on which the Index is based will be successful.
• Listing — We have listed the ETNs on NASDAQ under the symbol “USOI”. As long as an active secondary market in the ETNs exist, we expect that investors will purchase and sell the ETNs primarily in this secondary market. We are not required to maintain any listing of the ETNs on NASDAQ or any other exchange. Under certain circumstances, the ETNs may be subject to delisting by the NYSE Arca. We have not and do not intend to list the ETNs on any other exchange. No key information document required by Regulation (EU) No 1286/2014 (as amended) has been prepared as the ETNs are not available to retail investors in the European Economic Area. In addition, we are not obliged to, and may not, sell any additional ETNs. We may suspend or cease issuances and sales of the ETNs at any time, at our sole discretion.
• Indicative Value and Secondary Market — The indicative value is not the same as the closing price or any other trading price of the ETNs in the secondary market. The trading price of the ETNs at any time is the price at which you may be able to sell your ETNs in the secondary market at such time, if one exists. The trading price of the ETNs at any time may vary significantly from the indicative value of such ETNs at such time. Before trading in the secondary market, you should compare the indicative value with the thenprevailing trading price of the ETNs.
• Concentration Risk — The return on the ETNs is linked to the performance of the price version of the Index, which measures the return of a covered call strategy on the Reference Oil Shares. Your investment reflects a concentrated exposure to a single asset and, therefore, could experience greater volatility than a more diversified investment. In addition, there are Notional Transaction Costs associated with the implementation of the Index strategy.
• Fees and Costs — The ETNs should not be expected to track the performance of the Reference Oil Shares or the spot price of WTI crude oil because of the fees and expenses applied to each of the Reference Oil Shares and the ETN, the design of the Index methodology which includes Notional Transaction Costs and limits upside participation in any appreciation of the Reference Oil Shares, as well as lack of correlation between changes in prices of the Reference Oil Shares and the spot price of WTI crude oil. The Index, the Reference Oil Shares and the ETNs are each subject to fees and costs. The level of the Index is reduced by the Notional Transaction Costs. The annual expense ratio of the United States Oil Fund® is currently 0.72%. The indicative value of the ETNs and the amount of your payment at maturity or upon early redemption or acceleration are reduced by the Daily Investor Fee and in the case of an early redemption, your payment is further reduced by the Early Redemption Charge. In addition, the level of the Index and, therefore, the value of the ETNs will decline each month in connection with the Index Distribution and Coupon Amount. For all of the foregoing reasons, the performance of the ETNs should not be expected to mirror the performance of the Reference Oil Shares or the spot price of WTI crude oil. The Index replicates notional positions in Reference Oil Shares and options. As an owner of the ETNs, you will not have rights that holders of the Reference Oil Shares or any call options on the Reference Oil Shares may have, and you will have no right to receive delivery of any components of the Index or any interest in WTI crude oil.
• Optional Acceleration — The ETNs are subject to Optional Acceleration. Credit Suisse may accelerate all outstanding ETNs at any time on or after May 9, 2017, and upon any such acceleration you may receive less than, and possibly may lose all of, your original investment in the ETNs.
• Federal Income Taxes — Tax consequences of the ETNs are uncertain and potential investors should consult their tax advisors regarding the U.S. federal income tax consequences of an investment in the ETNs.
• Conflicts of Interest — We and our affiliates play a variety of roles in connection with the issuance of the ETNs, including acting as Calculation Agent, an Index Sponsor and as agent of the Issuer for the offering of the ETNs, and hedging our obligations under the ETNs. The Calculation Agent will, among other things, decide the amount of the return paid out to you on your ETNs at maturity or upon redemption or acceleration. As an Index Sponsor, our affiliate is responsible for decisions and determinations relating to the Index, including the interpretation of the Index methodology, that may impact the level of the Index and, in turn, the indicative value of the ETNs. In performing these duties, the economic interests of us and our affiliates are potentially adverse to your interests as an investor in the ETNs.
