Redemption Amount:

If the securities are not automatically redeemed, you will be entitled to receive a Redemption Amount in cash at maturity that will equal the principal amount of the securities you hold multiplied by the sum of one plus the Underlying Return of the Lowest Performing Underlying, calculated as set forth below. Any payment on the securities is subject to our ability to pay our obligations as they become due.

Underlying Return:	For each Underlying, the Underlying Return is expressed as a percentage and is calculated as follows:
	•	If a Knock-In Event does not occur, the Underlying Return for such Underlying will equal the Contingent Minimum Return.
	•	If a Knock-In Event occurs, the Underlying Return for such Underlying will equal:
			Final Level – Initial Level Initial Level	, subject to a maximum of zero
	If the securities are not automatically redeemed prior to maturity and a Knock-In Event occurs, the Underlying Return of the Lowest Performing Underlying will be negative and you will receive less than the principal amount of your securities at maturity. You could lose your entire investment.
Lowest Performing Underlying:	The Underlying with the lowest Underlying Return.
Knock-In Event:	A Knock-In Event occurs if the Final Level of either Underlying is equal to or less than its Knock-In Level.
Knock-In Level:	For each Underlying, as set forth in the table above.
Initial Level:	For each Underlying, as set forth in the table above.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.

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. We may, without the consent of the registered holder of the securities and the owner of any beneficial interest in the securities, amend the securities to conform to its terms as set forth in this pricing supplement and the documents listed above, and the trustee is authorized to enter into any such amendment without any such consent. You should carefully consider, among other things, the matters set forth in “Risk Factors” in the product supplement and “Selected Risk Considerations” in this pricing supplement, “Foreign Currency Risks” in the accompanying prospectus, and any risk factors we describe in the combined Annual Report on Form 20-F of Credit Suisse Group AG and us incorporated by reference therein, and any additional risk factors we describe in future filings we make with the SEC under the Securities Exchange Act of 1934, as amended, 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.

Hypothetical Redemption Amounts

The table and examples below illustrate hypothetical payments upon Automatic Redemption and Redemption Amounts payable at maturity, as applicable, on a $1,000 investment in the securities for a range of scenarios. The table and examples reflect that (i) for each Underlying, the Trigger Level is 100% of the Initial Level of such Underlying, (ii) the Automatic Redemption Premiums applicable to the first, second, third and fourth Observation Dates are $176, $352, $528 and $704, respectively, (iii) the Knock-In Level for each Underlying is 70% of the Initial Level of such Underlying and (iv) the Contingent Minimum Return is 10.00%. The actual Trigger Levels and Knock-In Levels are set forth on the cover of this pricing supplement. The examples are intended to illustrate hypothetical calculations of the payment upon Automatic Redemption and the Redemption Amount payable at maturity, as applicable, and are provided for illustration purposes only. The actual payment upon Automatic Redemption or the Redemption Amount payable at maturity, as applicable, that a purchaser of the securities will be entitled to receive will depend on several variables, including, but not limited to (a) whether the closing level of each Underlying is equal to or greater than its Trigger Level on any Observation Date, (b) the Final Level of each Underlying determined on the Valuation Date and (c) whether a Knock-In Event occurs. It is not possible to predict whether a Trigger Event or a Knock-In Event will occur, and in the event that the securities are not automatically redeemed and there is a Knock-In Event, by how much the level of the Lowest Performing Underlying has decreased from its Initial Level to its Final Level. You should consider carefully whether the securities are suitable to your investment goals. Any payment on the securities is subject to our ability to pay our obligations as they become due. The numbers appearing in the following table and the examples below have been rounded for ease of analysis.

TABLE 1: The securities are not automatically redeemed.

Principal Amount of Securities	Percentage Change from the Initial Level to the Final Level of the Lowest Performing Underlying	Redemption Amount per $1,000 Principal Amount of Securities
$1,000	−0.01%	$1,100
$1,000	−10%	$1,100
$1,000	−20%	$1,100
$1,000	−30%	$700
$1,000	−40%	$600
$1,000	−50%	$500
$1,000	−60%	$400
$1,000	−70%	$300
$1,000	−80%	$200
$1,000	−90%	$100
$1,000	−100%	$0

Example 1: The closing level of each Underlying on the first Observation Date is equal to or greater than its Trigger Level.

Underlying	Closing Level of each Underlying on the first Observation Date	Closing Level of each Underlying on the second Observation Date	Closing Level of each Underlying on the third Observation Date	Closing Level of each Underlying on the fourth Observation Date / Final Level
SPX	110% of Initial Level	N/A	N/A	N/A
XOP	100% of Initial Level	N/A	N/A	N/A

Since the closing level of each Underlying is equal to or greater than its Trigger Level on the first Observation Date, the securities are automatically redeemed.

Therefore, the cash payment per $1,000 principal amount of securities is equal to $1,000 plus the Automatic Redemption Premium applicable to the first Observation Date:

= $1,000 + $176 = $1,176

Example 2: The securities are not automatically redeemed on the first Observation Date and the closing level of each Underlying on the second Observation Date is equal to or greater than its Trigger Level.

Underlying	Closing Level of each Underlying on the first Observation Date	Closing Level of each Underlying on the second Observation Date	Closing Level of each Underlying on the third Observation Date	Closing Level of each Underlying on the fourth Observation Date / Final Level
SPX	90% of Initial Level	125% of Initial Level	N/A	N/A
XOP	95% of Initial Level	100% of Initial Level	N/A	N/A

Since the closing level of each Underlying is equal to or greater than its Trigger Level on the second Observation Date, the securities are automatically redeemed.

Therefore, the cash payment per $1,000 principal amount of securities is equal to $1,000 plus the Automatic Redemption Premium applicable to the second Observation Date:

= $1,000 + $352 = $1,352

Example 3: The securities are not automatically redeemed on the first Observation Date or the second Observation Date and the closing level of each Underlying on the third Observation Date is equal to or greater than its Trigger Level.

Underlying	Closing Level of each Underlying on the first Observation Date	Closing Level of each Underlying on the second Observation Date	Closing Level of each Underlying on the third Observation Date	Closing Level of each Underlying on the fourth Observation Date / Final Level
SPX	80% of Initial Level	80% of Initial Level	110% of Initial Level	N/A
XOP	95% of Initial Level	70% of Initial Level	100% of Initial Level	N/A

Since the closing level of each Underlying is equal to or greater than its Trigger Level on the third Observation Date, the securities are automatically redeemed.

Therefore, the cash payment per $1,000 principal amount of securities is equal to $1,000 plus the Automatic Redemption Premium applicable to the third Observation Date:

= $1,000 + $528 = $1,528

Example 4: The securities are not automatically redeemed on the first Observation Date, the second Observation Date or the third Observation Date and the closing level of each Underlying on the fourth Observation Date is equal to or greater than its Trigger Level.

Underlying	Closing Level of each Underlying on the first Observation Date	Closing Level of each Underlying on the second Observation Date	Closing Level of each Underlying on the third Observation Date	Closing Level of each Underlying on the fourth Observation Date / Final Level
SPX	80% of Initial Level	80% of Initial Level	95% of Initial Level	100% of Initial Level
XOP	95% of Initial Level	70% of Initial Level	90% of Initial Level	110% of Initial Level

Since the closing level of each Underlying is equal to or greater than its Trigger Level on the fourth Observation Date, the securities are automatically redeemed.

Therefore, the cash payment per $1,000 principal amount of securities is equal to $1,000 plus the Automatic Redemption Premium applicable to the fourth Observation Date:

= $1,000 + $704 = $1,704

Example 5: The securities are not automatically redeemed; a Knock-In Event occurs because the Final Level of an Underlying is equal to or less than its Knock-In Level.

Underlying	Closing Level of each Underlying on the first Observation Date	Closing Level of each Underlying on the second Observation Date	Closing Level of each Underlying on the third Observation Date	Closing Level of each Underlying on the fourth Observation Date / Final Level
SPX	95% of Initial Level	70% of Initial Level	80% of Initial Level	65% of Initial Level
XOP	80% of Initial Level	80% of Initial Level	65% of Initial Level	80% of Initial Level

Since the Final Level of an Underlying is less than its Knock-In Level, a Knock-In Event occurs.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of SPX – Initial Level of SPX Initial Level of SPX	; subject to a maximum of 0.00

= −0.35

The Redemption Amount = $1,000 × (1 + Underlying Return)

= $1,000 × (1 - 0.35) = $650

Example 6: The securities are not automatically redeemed; a Knock-In Event does not occur.

Underlying	Closing Level of each Underlying on the first Observation Date	Closing Level of each Underlying on the second Observation Date	Closing Level of each Underlying on the third Observation Date	Closing Level of each Underlying on the fourth Observation Date / Final Level
SPX	80% of Initial Level	80% of Initial Level	90% of Initial Level	85% of Initial Level
XOP	95% of Initial Level	75% of Initial Level	85% of Initial Level	80% of Initial Level

Since the Final Level of an Underlying is not equal to or less than the Knock-In Level, a Knock-In Event does not occur.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal the Contingent Minimum Return of 10.00%.

The Redemption Amount = $1,000 × (1 + Underlying Return)

= $1,000 × (1 + 0.10) = $1,100

Selected Risk Considerations

An investment in the securities involves significant risks. Investing in the securities is not equivalent to investing directly in the Underlyings. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement.

•

YOU MAY RECEIVE LESS THAN THE PRINCIPAL AMOUNT AT MATURITY — You may receive less at maturity than you originally invested in the securities, or you may receive nothing. If the securities are not automatically redeemed and a Knock-In Event occurs, you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, the Redemption Amount you will be entitled to receive will be less than the principal amount of the securities, and you will lose your entire investment if the Final Level of the Lowest Performing Underlying falls to zero. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, by how much the level of the Lowest Performing Underlying has decreased from its Initial Level to its Final Level. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE — Investors are dependent on our ability to pay all amounts due on the securities and, therefore, if we were to default on our obligations, you may not receive any amounts owed to you under the securities. 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.

•

YOU WILL NOT BE ENTITLED TO ANY MINIMUM RETURN IF A KNOCK-IN EVENT OCCURS — If the securities are not automatically redeemed and if the Final Level of an Underlying is equal to or less than its Knock-In Level, you will not be entitled to receive the Contingent Minimum Return of 10.00% on the securities and you will be fully exposed to any depreciation of the level of the Lowest Performing Underlying from its Initial Level to its Final Level and you will lose 1.00% of the principal amount of your investment for every 1.00% decrease in the Final Level as compared to the Initial Level. Under these circumstances, you will lose some or all of your investment at maturity and you will be fully exposed to any depreciation in the level of the Lowest Performing Underlying.

•

THE SECURITIES DO NOT PAY INTEREST — We will not pay interest on the securities. You may receive less at maturity than you could have earned on ordinary interest-bearing debt securities with similar maturities, including other of our debt securities, since the Redemption Amount at maturity is based on the appreciation or depreciation of the Underlyings. Because the Redemption Amount due at maturity may be less than the amount originally invested in the securities, the return on the securities (the effective yield to maturity) may be negative. Even if it is positive, the return payable on each security may not be enough to compensate you for any loss in value due to inflation and other factors relating to the value of money over time.

•

APPRECIATION POTENTIAL IS LIMITED — If a Trigger Event occurs, the appreciation potential of the securities will be limited to the Automatic Redemption Premium applicable to the relevant Observation Date, as set forth on the cover of this pricing supplement, regardless of any appreciation in the Underlyings, which may be significant. If a Trigger Event and a Knock-In Event do not occur, for each $1,000 principal amount of securities, you will be entitled to receive at maturity $1,000 multiplied by the sum of one plus the Contingent Minimum Return of 10.00%. In this case, the maximum Redemption Amount of the securities at maturity will be $1,100 per $1,000 principal amount of securities. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

IF A KNOCK-IN EVENT OCCURS, YOUR RETURN WILL BE BASED ON THE INDIVIDUAL PERFORMANCE OF THE LOWEST PERFORMING UNDERLYING — If the securities are not automatically redeemed and a Knock-In Event occurs, your return will be based on the individual performance of the Lowest Performing Underlying and your return will be negative even if the Knock-In Event occurs with respect to only one Underlying.

•

THE RETURN ON THE SECURITIES WILL BE AFFECTED BY THE KNOCK-IN LEVEL FOR EACH UNDERLYING AND THE OCCURRENCE OF A KNOCK-IN EVENT — The return on the securities will be affected by the Knock-In Level for each Underlying and whether a Knock-In Event occurs. If the securities are not automatically redeemed and the Final Level of the Lowest Performing Underlying is less than its Knock-In Level, a Knock-In Event will have occurred and you will receive substantially less than your principal amount at maturity.

•

YOU WILL BE SUBJECT TO RISKS RELATING TO THE RELATIONSHIP BETWEEN THE UNDERLYINGS — The securities are linked to the individual performance of each Underlying. As such, the securities will perform poorly if only one of the Underlyings performs poorly. Each additional Underlying to which the securities are linked increases the risk that the securities will perform poorly. By investing in the securities, you assume the risk that the performance of at least one of the Underlyings will be negative, regardless of the performance of any other Underlying.

It is impossible to predict the relationship between the Underlyings. If the performances of the Underlyings exhibit no relationship to each other, it is more likely that one of the Underlyings will cause the securities to perform poorly. However, if the performances of the equity securities included in each Underlying are related such that the performances of the Underlyings are correlated, then there is less likelihood that only one Underlying will cause the securities to perform poorly. Furthermore, to the extent that each Underlying represents a different market segment or market sector, the risk of one Underlying performing poorly is greater. As a result, you are not only taking market risk on each Underlying, you are also taking a risk relating to the relationship among the Underlyings.

•

THERE ARE RISKS ASSOCIATED WITH THE SPDR^® S&P^® OIL & GAS EXPLORATION & PRODUCTION ETF — Although shares of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF (the “Reference Fund”) are listed for trading on a national securities exchange and a number of similar products have been traded on various national securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of the Reference Fund or that there will be liquidity in the trading market. The Reference Fund is subject to management risk, which is the risk that a fund's investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Pursuant to the Reference Fund's investment strategy or otherwise, its investment advisor may add, delete or substitute the assets held by the Reference Fund. Any of these actions could adversely affect the price of the shares of the Reference Fund and consequently the value of the securities. For additional information on the Reference Fund, see “The Reference Funds—The SPDR^® Funds—The SPDR^® S&P^® Oil & Gas Exploration & Production ETF” in the accompanying underlying supplement.

•

THE PERFORMANCE OF THE REFERENCE FUND MAY NOT CORRELATE TO THE PERFORMANCE OF THE TRACKED INDEX — The Reference Fund will generally invest in all of the equity securities included in the S&P Oil & Gas Exploration & Production Select Industry Index, the “Tracked Index” for the Reference Fund. There may, however, be instances where the Reference Fund’s investment advisor, may choose to overweight another stock in the Tracked Index, purchase securities not included in the Tracked Index that the investment advisor believes are appropriate to substitute for a security included in the Tracked Index or utilize various combinations of other available investment techniques. In addition, the performance of the Reference Fund will reflect additional transaction costs and fees that are not included in the calculation of the Tracked Index. Finally, because the shares of the Reference Fund are traded on a national securities exchange and are subject to market supply and investor demand, the market value of one share of the Reference Fund may differ from the net asset value per share of the Reference Fund. For these reasons, the performance of the Reference Fund may not correlate with the performance of the Tracked Index. For additional information about the variation between the performance of the Reference Fund and the performance of the Tracked Index, see “The Reference Funds—The SPDR^®Funds—The SPDR^® S&P^® Oil & Gas Exploration & Production ETF” in the accompanying underlying supplement.

The Stocks Included in THE REFERENCE FUND are Concentrated in One Particular Sector — All of the stocks included in the Reference Fund are issued by companies in the oil and gas exploration and production sector. As a result, the stocks that will

determine the performance of the Reference Fund are concentrated in the oil and gas exploration and production sector industry. Although an investment in the securities will not give holders any ownership or other direct interests in the stocks held by the Reference Fund, the return on an investment in the securities will be subject to certain risks associated with a direct equity investment in companies in the oil and gas exploration and production. Accordingly, by investing in the securities, you will not benefit from the diversification which could result from an investment linked to companies that operate in a broader range of sectors.

•

RISKS ASSOCIATED WITH INVESTMENTS IN SECURITIES WITH CONCENTRATION IN THE OIL AND GAS EXPLORATION AND PRODUCTION INDUSTRY — The Reference Fund’s assets will be concentrated in the oil and gas exploration and production industry, which means the Reference Fund will be more affected by the performance of the oil and gas exploration and production industry versus an exchange-traded fund that is more diversified. Companies in the oil and gas sector develop and produce crude oil and natural gas and provide drilling and other energy resources production and distribution related services. Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for energy products in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. Securities of companies in the oil and gas exploration and production industry are at times subject to swift price and supply fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies. Weak demand for the companies’ products or services or for energy products and services in general, as well as negative developments in these other areas, would adversely impact the Reference Fund’s performance. In addition, oil and gas exploration and production can be significantly affected by natural disasters as well as changes in exchange rates, interest rates, government regulation, world events and economic conditions. These companies may also be at risk for environmental damages claims which may affect the stock price of the companies included in the Reference Fund and your securities.

•

THE ESTIMATED VALUE OF THE SECURITIES ON THE TRADE DATE MAY BE LESS THAN THE PRICE TO PUBLIC — The initial estimated value of your securities on the Trade Date (as determined by reference to our pricing models and our internal funding rate) may be significantly less than the original Price to Public. The Price to Public of the securities includes the agent’s discounts or commissions as well as transaction costs such as expenses incurred to create, document and market the securities and the cost of hedging our risks as issuer of the securities through one or more of our affiliates (which includes a projected profit). These costs will be effectively borne by you as an investor in the securities. These amounts will be retained by Credit Suisse or our affiliates in connection with our structuring and offering of the securities (except to the extent discounts or commissions are reallowed to other broker-dealers or any costs are paid to third parties).

On the Trade Date, we value the components of the securities in accordance with our pricing models. These include a fixed income component valued using our internal funding rate, and individual option components valued using mid-market pricing. Our option valuation models are proprietary. They take into account factors such as interest rates, volatility and time to maturity of the securities, and they rely in part on certain assumptions about future events, which may prove to be incorrect.

Because Credit Suisse’s pricing models may differ from other issuers’ valuation models, and because funding rates taken into account by other issuers may vary materially from the rates used by Credit Suisse (even among issuers with similar creditworthiness), our estimated value at any time may not be comparable to estimated values of similar securities of other issuers.

•

EFFECT OF INTEREST RATE USED IN STRUCTURING THE SECURITIES — The internal funding rate we use in structuring notes such as these securities is typically lower than the interest rate that is reflected in the yield on our conventional debt securities of similar maturity in the secondary market (our “secondary market credit spreads”). If on the Trade Date our internal funding rate is lower than our secondary market credit spreads, we expect that the economic terms of the securities will generally be less favorable to you than they would have been if our secondary market credit spread had been used in structuring the securities. We will also use our internal funding rate to determine the

price of the securities if we post a bid to repurchase your securities in secondary market transactions. See “—Secondary Market Prices” below.

•

SECONDARY MARKET PRICES — If Credit Suisse (or an affiliate) bids for your securities in secondary market transactions, which we are not obligated to do, the secondary market price (and the value used for account statements or otherwise) may be higher or lower than the Price to Public and the estimated value of the securities on the Trade Date. The estimated value of the securities on the cover of this pricing supplement does not represent a minimum price at which we would be willing to buy the securities in the secondary market (if any exists) at any time. The secondary market price of your securities at any time cannot be predicted and will reflect the then-current estimated value determined by reference to our pricing models and other factors. These other factors include our internal funding rate, customary bid and ask spreads and other transaction costs, changes in market conditions and any deterioration or improvement in our creditworthiness. In circumstances where our internal funding rate is lower than our secondary market credit spreads, our secondary market bid for your securities could be more favorable than what other dealers might bid because, assuming all else equal, we use the lower internal funding rate to price the securities and other dealers might use the higher secondary market credit spread to price them. Furthermore, assuming no change in market conditions from the Trade Date, the secondary market price of your securities will be lower than the Price to Public because it will not include the agent’s discounts or commissions and hedging and other transaction costs. If you sell your securities to a dealer in a secondary market transaction, the dealer may impose an additional discount or commission, and as a result the price you receive on your securities may be lower than the price at which we may repurchase the securities from such dealer.

We (or an affiliate) may initially post a bid to repurchase the securities from you at a price that will exceed the then-current estimated value of the securities. That higher price reflects our projected profit and costs that were included in the Price to Public, and that higher price may also be initially used for account statements or otherwise. We (or our affiliate) may offer to pay this higher price, for your benefit, but the amount of any excess over the then-current estimated value will be temporary and is expected to decline over a period of approximately 90 days.

The securities are not designed to be short-term trading instruments and any sale prior to maturity could result in a substantial loss to you. You should be willing and able to hold your securities to maturity.

CREDIT SUISSE IS SUBJECT TO SWISS REGULATION — As a Swiss bank, Credit Suisse is subject to regulation by governmental agencies, supervisory authorities and self-regulatory organizations in Switzerland. Such regulation is increasingly more extensive and complex and subjects Credit Suisse to risks. For example, pursuant to Swiss banking laws, the Swiss Financial Market Supervisory Authority (FINMA) may open resolution proceedings if there are justified concerns that Credit Suisse is over-indebted, has serious liquidity problems or no longer fulfills capital adequacy requirements. FINMA has broad powers and discretion in the case of resolution proceedings, which include the power to convert debt instruments and other liabilities of Credit Suisse into equity and/or cancel such liabilities in whole or in part. If one or more of these measures were imposed, such measures may adversely affect the terms and market value of the securities and/or the ability of Credit Suisse to make payments thereunder and you may not receive any amounts owed to you under the securities.

•

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, hedging our obligations under the securities and determining their estimated value. In performing these duties, the economic interests of us and our affiliates are potentially adverse to your interests as an investor in the securities. Further, hedging activities may adversely affect any payment on or the value of the securities. Any profit in connection with such hedging activities will be in addition to any other compensation that we and our affiliates receive for the sale of the securities, which creates an additional incentive to sell the securities to you.

•

UNPREDICTABLE ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE SECURITIES — In addition to the levels of the Underlyings, the value of the securities may be influenced by factors such as:

the expected and actual volatility of the Underlyings;

the expected and actual correlation, if any, between the Underlyings;

the time to maturity of the securities;

the dividend rate on the equity securities included in the Underlyings;

interest and yield rates in the market generally;

investors’ expectations with respect to the rate of inflation;

geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the components included in the Underlyings or markets generally and which may affect the levels of the Underlyings; 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.

•

NO OWNERSHIP RIGHTS RELATING TO THE UNDERLYINGS — Your return on the securities will not reflect the return you would realize if you actually owned the equity securities that comprise the Underlyings. The return on your investment is not the same as the total return based on the purchase of shares of the equity securities that comprise the Underlyings.

•

NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to the shares of the Reference Fund or the equity securities that comprise the Underlyings.

•

ANTI-DILUTION PROTECTION IS LIMITED — The Calculation Agent will make anti-dilution adjustments for certain events affecting the Reference Fund. However, an adjustment will not be required in response to all events that could affect the Reference Fund. If an event occurs that does not require the Calculation Agent to make an adjustment, or if an adjustment is made but such adjustment does not fully reflect the economics of such event, the value of the securities may be materially and adversely affected. See “Description of the Securities—Adjustments for a reference fund” in the accompanying product supplement.

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. Such hedging or trading activities on or prior to the Trade Date and during the term of the securities, including on the Observation Dates (including on the Valuation Date), could adversely affect the value of the Underlyings and, as a result, could decrease the amount you may receive on the securities at maturity. For

additional information, see “Supplemental Use of Proceeds and Hedging” in the accompanying product supplement.

Historical Information

The following graphs set forth the historical performance of the Underlyings based on the closing levels of such Underlyings from January 4, 2010 through August 21, 2015. The closing level of the S&P 500^® Index on August 21, 2015 was 1970.89. The closing level of one share of the SPDR^® S&P^® Oil & Gas Exploration & Production ETF on August 21, 2015 was $35.38. We obtained the historical information below from Bloomberg, without independent verification.

You should not take the historical levels of the Underlyings as an indication of future performance of the Underlyings or the securities. Any historical trend in the levels of the Underlyings during any period set forth below is not an indication that the levels of the Underlyings are more or less likely to increase or decrease at any time over the term of the securities.

For additional information on the S&P 500^® Index and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF, see “The Reference Indices—The S&P Dow Jones Indices—The S&P 500^® Index” and “The Reference Funds—The SPDR^® Funds—The SPDR^® S&P^® Oil & Gas Exploration & Production ETF” in the accompanying underlying supplement.

Material U.S. Federal Income Tax Considerations

The following discussion summarizes material U.S. federal income tax consequences of owning and disposing of the securities that may be relevant to holders of the securities that acquire their securities from us as part of the original issuance of the securities. This discussion applies only to holders that hold their securities as capital assets within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”). Further, this discussion does not address all of the U.S. federal income tax consequences that may be relevant to you in light of your individual circumstances or if you are subject to special rules, such as if you are:

a financial institution,

a mutual fund,

a tax-exempt organization,

a grantor trust,

certain U.S. expatriates,

an insurance company,

a dealer or trader in securities or foreign currencies,

a person (including traders in securities) using a mark-to-market method of accounting,

a person who holds the securities as a hedge or as part of a straddle with another position, constructive sale, conversion transaction or other integrated transaction, or

an entity that is treated as a partnership for U.S. federal income tax purposes.

The discussion is based upon the Code, law, regulations, rulings and decisions, in each case, as available and in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. Tax consequences under state, local and foreign laws are not addressed herein. No ruling from the U.S. Internal Revenue Service (the “IRS”) has been sought as to the U.S. federal income tax consequences of the ownership and disposition of the securities, and the following discussion is not binding on the IRS.

You should consult your tax advisor as to the specific tax consequences to you of owning and disposing of the securities, including the application of federal, state, local and foreign income and other tax laws based on your particular facts and circumstances.

Characterization of the Securities

There are no statutory provisions, regulations, published rulings, or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of your securities. Thus, the characterization of the securities is not certain. Our special tax counsel, Orrick, Herrington & Sutcliffe LLP, has advised that the securities should be treated, for U.S. federal income tax purposes, as prepaid financial contracts, with respect to the Underlyings that are eligible for open transaction treatment. In the absence of an administrative or judicial ruling to the contrary, we and, by acceptance of the securities, you agree to treat the securities for all tax purposes in accordance with such characterization. In light of the fact that we agree to treat the securities as prepaid financial contracts, the balance of this discussion assumes that the securities will be so treated.

You should be aware that the characterization of the securities as described above is not certain, nor is it binding on the IRS or the courts. Thus, it is possible that the IRS would seek to characterize your securities in a manner that results in tax consequences to you that are different from those described below. For example, the IRS might assert that securities with a term of more than one year constitute debt instruments that are “contingent payment debt instruments” that are subject to special tax rules under the applicable Treasury regulations governing the recognition of income over the term of your securities. If the securities were to be treated as contingent payment debt instruments, you would be required to include in income on an economic accrual basis over the term of the securities an amount of interest that is based upon the yield at which we would issue a non-contingent fixed-rate debt instrument with other terms and conditions similar to your securities (the comparable yield). The characterization of the securities as contingent payment debt instruments under these rules is likely to be adverse. However, if the securities had a term of one year or less, the rules for short-term debt obligations would apply rather than the rules for contingent payment debt instruments. Under Treasury regulations, a short-term

debt obligation is treated as issued at a discount equal to the difference between all payments on the obligation and the obligation’s issue price. A cash method U.S. Holder that does not elect to accrue the discount in income currently should include the payments attributable to interest on the securities as income upon receipt. Under these rules, any contingent payment would be taxable upon receipt by a cash basis taxpayer as ordinary interest income. You should consult your tax advisor regarding the possible tax consequences of characterization of the securities as contingent payment debt instruments or short-term debt obligations. It is also possible that the IRS would seek to characterize your securities as options, and thus as Code section 1256 contracts in the event that they are listed on a securities exchange. In such case, the securities would be marked-to-market at the end of the year and 40% of any gain or loss would be treated as short-term capital gain or loss, and the remaining 60% of any gain or loss would be treated as long-term capital gain or loss. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the securities for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of your securities for U.S. federal income tax purposes.

U.S. Holders

For purposes of this discussion, the term “U.S. Holder,” for U.S. federal income tax purposes, means a beneficial owner of securities that is (1) a citizen or resident of the United States, (2) a corporation (or an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust, if (a) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has in effect a valid election to be treated as a domestic trust for U.S. federal income tax purposes. If a partnership (or an entity treated as a partnership for U.S. federal income tax purposes) holds securities, the U.S. federal income tax treatment of such partnership and a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership, or a partner of a partnership, holding securities, you should consult your tax advisor regarding the tax consequences to you from the partnership’s purchase, ownership and disposition of the securities.

In accordance with the agreed-upon tax treatment described above (and subject to the discussion below under “Constructive Ownership Transaction Rules”), if the security provides for the payment of the redemption amount in cash based on the return of the Underlyings, upon receipt of the redemption amount of the security from us, a U.S. Holder will recognize gain or loss equal to the difference between the amount of cash received from us and the U.S. Holder’s tax basis in the security at that time. For securities with a term of more than one year, such gain or loss will be long-term capital gain or loss if the U.S. Holder has held the security for more than one year at maturity. For securities with a term of one year or less, such gain or loss will be short-term capital gain or loss. If the security provides for the payment of the redemption amount in physical shares or units of the Underlyings, the U.S. Holder should not recognize any gain or loss with respect to the security (other than with respect to cash received in lieu of fractional shares or units, as described below). A U.S. Holder will have a tax basis in all physical shares or units received (including for this purpose any fractional shares or units) equal to its tax basis in the security (generally its cost). A U.S. Holder’s holding period for any physical shares or units received will start on the day after the delivery of the physical shares or units. A U.S. Holder should generally recognize short-term capital gain or loss with respect to cash received in lieu of fractional shares or units in an amount equal to the difference between the amount of such cash received and the U.S. Holder’s basis in the fractional shares or units, which should be equal to the U.S. Holder’s basis in all of the physical shares or units (including the fractional shares or units), multiplied by a fraction, the numerator of which is the fractional shares or units and the denominator of which is all of the physical shares or units (including fractional shares or units).

Upon the sale or other taxable disposition of a security (and subject to the discussion below under “Constructive Ownership Transaction Rules”), a U.S. Holder generally will recognize gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. Holder’s tax basis in the security (generally its cost). For securities with a term of more than one year, such gain or loss will be long-term capital gain or loss if the U.S. Holder has held the security for more than one year at the time of disposition. For securities with a term of one year or less, such gain or loss will be short-term capital gain or loss.

Constructive Ownership Transaction Rules

All or a portion of gain arising from certain “constructive ownership transactions” may be recharacterized as ordinary income, and certain interest charges may be imposed with respect to any such recharacterized income. These rules by their terms may apply to any gain derived from the securities if the securities reference an equity interest in a “pass-thru entity” within the meaning of Code section 1260, which includes shares in an exchange traded fund. If the term of the securities is one year or greater and the underlying includes an equity interest in an exchange traded fund, the IRS might assert that the constructive ownership transaction rules of Code section 1260 apply.

If the securities are treated as a constructive ownership transaction, any gain therefrom that otherwise would be long-term capital gain in excess of the “net underlying long-term capital gain” will be treated as ordinary income, and an interest charge will apply as if such income had accrued for tax purposes at a constant yield over the term of the securities. There is a presumption that all of the gain realized that otherwise would have been long-term capital gain is subject to recharacterization as ordinary income and an interest charge, unless the contrary is demonstrated by clear and convincing evidence. Accordingly, any gain a U.S. Holder realizes from the sale, exchange or redemption of its securities in excess of the amount of long-term capital gain that it can establish that it would have realized had it (1) invested in the underlying (rather than the securities) on the issue date of the securities, and (2) sold the underlying on the date of sale, exchange or redemption of the securities, could be recharacterized as ordinary income and subject to an interest charge, as described above.

Code section 1260 also provides that the U.S. Department of the Treasury is to issue regulations that would exclude from the scope of Code section 1260 certain forward contracts that do not convey “substantially all of the economic return” with respect to the applicable reference asset, which in the case of the securities would be all or a portion of the underlying. However, no such regulations have been issued despite the fact that Code section 1260 was enacted in 1999, and there can be no assurance that any regulations that may be issued would apply to securities that are issued before such regulations. Thus, although we believe that the securities should not be considered to convey substantially all the economic return with respect to the underlying, in the absence of regulations, there can be no assurance that the securities would not be so considered or that Code section 1260 would not otherwise apply to the securities.

You should consult with your tax advisor regarding the possible application of the constructive ownership transaction rules to the securities.

Medicare Tax

Certain U.S. Holders that are individuals, estates, and trusts must pay a 3.8% tax (the “Medicare Tax”) on the lesser of the U.S. person’s (1) “net investment income” or “undistributed net investment income” in the case of an estate or trust and (2) the excess of modified adjusted gross income over a certain specified threshold for the taxable year. “Net investment income” generally includes income from interest, dividends, and net gains from the disposition of property (such as the securities) unless such income or net gains are derived in the ordinary course of a trade or business (other than a trade or business that is a passive activity with respect to the taxpayer or a trade or business of trading in financial instruments or commodities). Net investment income may be reduced by allowable deductions properly allocable to such gross income or net gain. Any interest earned or deemed earned on the securities and any gain on sale or other taxable disposition of the securities will be subject to the Medicare Tax. If you are an individual, estate, or trust, you are urged to consult with your tax advisor regarding application of the Medicare Tax to your income and gains in respect of your investment in the securities.

Securities Held Through Foreign Entities

Under certain provisions of the “Hiring Incentives to Restore Employment Act,” generally referred to as “FATCA,” and recently finalized regulations, a 30% withholding tax is imposed on “withholdable payments” and certain “passthru payments” made to “foreign financial institutions” (as defined in the regulations or an applicable intergovernmental agreement) (and their more than 50% affiliates) unless the payee foreign financial institution agrees, among other things, to disclose the identity of any U.S. individual with an account at the institution (or the institution’s affiliates) and to annually report certain information about such account. The term “withholdable payments” generally includes (1) payments of fixed or determinable annual or periodical gains, profits, and income (“FDAP”), in each case, from sources within the United States, and (2) gross proceeds from the sale of

any property of a type which can produce interest or dividends from sources within the United States. “Passthru payments” means any withholdable payment and any foreign passthru payment. To avoid becoming subject to the 30% withholding tax on payments to them, we and other foreign financial institutions may be required to report information to the IRS regarding the holders of the securities and, in the case of holders who (i) fail to provide the relevant information, (ii) are foreign financial institutions who have not agreed to comply with these information reporting requirements, or (iii) hold the securities directly or indirectly through such non-compliant foreign financial institutions, we may be required to withhold on a portion of payments under the securities. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or certify that they do not have any substantial United States owners) to withhold tax at a rate of 30%. If payments on the securities are determined to be from sources within the United States, we will treat such payments as withholdable payments for these purposes.

Withholding under FATCA will apply to all withholdable payments and certain passthru payments without regard to whether the beneficial owner of the payment is a U.S. person, or would otherwise be entitled to an exemption from the imposition of withholding tax pursuant to an applicable tax treaty with the United States or pursuant to U.S. domestic law. Unless a foreign financial institution is the beneficial owner of a payment, it will be subject to refund or credit in accordance with the same procedures and limitations applicable to other taxes withheld on FDAP payments provided that the beneficial owner of the payment furnishes such information as the IRS determines is necessary to determine whether such beneficial owner is a United States owned foreign entity and the identity of any substantial United States owners of such entity.

Pursuant to the recently finalized regulations described above and IRS Notice 2013-43, and subject to the exceptions described below, FATCA’s withholding regime generally will apply to (i) withholdable payments (other than gross proceeds of the type described above) made after June 30, 2014 (other than certain payments made with respect to a “preexisting obligation,” as defined in the regulations); (ii) payments of gross proceeds of the type described above with respect to a sale or disposition occurring after December 31, 2016; and (iii) foreign passthru payments made after the later of December 31, 2016, or the date that final regulations defining the term ”foreign passthru payment” are published. Notwithstanding the foregoing, the provisions of FATCA discussed above generally will not apply to (a) any obligation (other than an instrument that is treated as equity for U.S. tax purposes or that lacks a stated expiration or term) that is outstanding on July 1, 2014 (a “grandfathered obligation”); (b) any obligation that produces withholdable payments solely because the obligation is treated as giving rise to a dividend equivalent pursuant to Code section 871(m) and the regulations thereunder that is outstanding at any point prior to six months after the date on which obligations of its type are first treated as giving rise to dividend equivalents; and (c) any agreement requiring a secured party to make payments with respect to collateral securing one or more grandfathered obligations (even if the collateral is not itself a grandfathered obligation). Thus, if you hold your securities through a foreign financial institution or foreign entity, a portion of any of your payments may be subject to 30% withholding.

Non-U.S. Holders Generally

Except as provided under “Securities Held Through Foreign Entities” and “Substitute Dividend and Dividend Equivalent Payments,” payments made with respect to the securities to a holder of the securities that is not a U.S. Holder (a “Non-U.S. Holder”) and that has no connection with the United States other than holding its securities will not be subject to U.S. withholding tax, provided that such Non-U.S. Holder complies with applicable certification requirements. Any gain realized upon the sale or other disposition of the securities by a Non-U.S. Holder generally will not be subject to U.S. federal income tax unless (1) such gain is effectively connected with a U.S. trade or business of such Non-U.S. Holder or (2) in the case of an individual, such individual is present in the United States for 183 days or more in the taxable year of the sale or other disposition and certain other conditions are met. Any effectively connected gains described in clause (1) above realized by a Non-U.S. Holder that is, or is taxable as, a corporation for U.S. federal income tax purposes may also, under certain circumstances, be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

Non-U.S. Holders that are subject to U.S. federal income taxation on a net income basis with respect to their investment in the securities should refer to the discussion above relating to U.S. Holders.

Substitute Dividend and Dividend Equivalent Payments

The Code and regulations thereunder treat a “dividend equivalent” payment as a dividend from sources within the United States. Unless reduced by an applicable tax treaty with the United States, such payments generally will be subject to U.S. withholding tax. A “dividend equivalent” payment is (i) a substitute dividend payment made pursuant to a securities lending or a sale-repurchase transaction that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, (ii) a payment made pursuant to a “specified notional principal contract” (a “specified NPC”) that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, and (iii) any other payment determined by the IRS to be substantially similar to a payment described in the preceding clauses (i) and (ii). For payments made before January 1, 2016, the regulations provide that a specified NPC is any NPC if (a) in connection with entering into the contract, any long party to the contract transfers the underlying security to any short party to the contract, (b) in connection with the termination of the contract, any short party to the contract transfers the underlying security to any long party to the contract, (c) the underlying security is not readily tradable on an established securities market, or (d) in connection with entering into the contract, the underlying security is posted as collateral by any short party to the contract with any long party to the contract.

Proposed regulations provide that a dividend equivalent is (i) any payment of a substitute dividend made pursuant to a securities lending or sale-repurchase transaction that references the payment of a dividend from an underlying security, (ii) any payment made pursuant to a specified NPC that references the payment of a dividend from an underlying security, (iii) any payment made pursuant to a “specified equity-linked instrument” (a “specified ELI”) that references the payment of a dividend from an underlying security, or (iv) any other substantially similar payment. An underlying security is any interest in an entity taxable as a domestic corporation if a payment with respect to that interest could give rise to a U.S. source dividend. An ELI is a financial instrument (other than a securities lending or sale-repurchase transaction or an NPC) or combination of financial instruments that references one or more underlying securities to determine its value, including a futures contract, forward contract, option, debt instrument, or other contractual arrangement. For payments made after December 31, 2015, a specified NPC is any NPC that has a delta of 0.70 or greater with respect to an underlying security at the time of acquisition. For payments made after December 31, 2015, a specified ELI is any ELI issued on or after 90 days after the date the proposed regulations are finalized that has a delta of 0.70 or greater with respect to an underlying security at the time of acquisition. The delta of an NPC or ELI is the ratio of the change in the fair market value of the contract to the change in the fair market value of the property referenced by the contract. If an NPC or ELI references more than one underlying security, a separate delta must be determined with respect to each underlying security without taking into account any other underlying security or other property or liability. If an NPC (or ELI) references more than one underlying security, the NPC (or ELI) is a specified NPC (or specified ELI) only with respect to underlying securities for which the NPC (or ELI) has a delta of 0.70 or greater at the time that the long party acquires the NPC (or ELI). The proposed regulations provide an exception for qualified indices that satisfy certain criteria; however, it is not entirely clear how the proposed regulations will apply to securities that are linked to certain indices or baskets. The proposed regulations provide that a payment includes a dividend equivalent payment whether there is an explicit or implicit reference to a dividend with respect to the underlying security.

We will treat any portion of a payment or deemed payment on the securities (including, if appropriate, the payment of the purchase price) that is substantially similar to a dividend as a dividend equivalent payment, which will be subject to U.S. withholding tax unless reduced by an applicable tax treaty and a properly executed IRS Form W-8 (or other qualifying documentation) is provided. If withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld. The proposed regulations are extremely complex. Non-U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them of these proposed regulations and whether payments or deemed payments on the securities constitute dividend equivalent payments.

U.S. Federal Estate Tax Treatment of Non-U.S. Holders

A security may be subject to U.S. federal estate tax if an individual Non-U.S. Holder holds the security at the time of his or her death. The gross estate of a Non-U.S. Holder domiciled outside the United States includes only property situated in the United States. Individual Non-U.S. Holders should consult their tax advisors regarding the U.S. federal estate tax consequences of holding the securities at death.

IRS Notice and Proposed Legislation on Certain Financial Transactions

In Notice 2008-2, the IRS and the Treasury Department stated they are considering issuing new regulations or other guidance on whether holders of an instrument such as the securities should be required to accrue income during the term of the instrument. The IRS and Treasury Department also requested taxpayer comments on (1) the appropriate method for accruing income or expense (e.g., a mark-to-market methodology or a method resembling the noncontingent bond method), (2) whether income and gain on such an instrument should be ordinary or capital, and (3) whether foreign holders should be subject to withholding tax on any deemed income accrual. Additionally, unofficial statements made by IRS officials have indicated that they will soon be addressing the treatment of prepaid forward contracts in proposed regulations.

Accordingly, it is possible that regulations or other guidance may be issued that require holders of the securities to recognize income in respect of the securities prior to receipt of any payments thereunder or sale thereof. Any regulations or other guidance that may be issued could result in income and gain (either at maturity or upon sale) in respect of the securities being treated as ordinary income. It is also possible that a Non-U.S. Holder of the securities could be subject to U.S. withholding tax in respect of the securities under such regulations or other guidance. It is not possible to determine whether such regulations or other guidance will apply to your securities (possibly on a retroactive basis). You are urged to consult your tax advisor regarding Notice 2008-2 and its possible impact on you.

Members of Congress have from time-to-time proposed legislation relating to financial instruments, including legislation that would require holders to annually mark to market affected financial instruments (potentially including the securities). These or other potential changes in law could adversely affect the tax treatment of the securities and may be applied with retroactive effect. You are urged to consult your tax advisor regarding how any such potential changes in law could affect you.

Information Reporting Regarding Specified Foreign Financial Assets

The Code and regulations thereunder generally require individual U.S. Holders (“specified individuals”) and “specified domestic entities” with an interest in any “specified foreign financial asset” to file an annual report on IRS Form 8938 with information relating to the asset, including the maximum value thereof, for any taxable year in which the aggregate value of all such assets is greater than $50,000 on the last day of the taxable year or $75,000 at any time during the taxable year. Certain individuals are permitted to have an interest in a higher aggregate value of such assets before being required to file a report. Specified foreign financial assets include, with some limited exceptions, any financial account maintained at a foreign financial institution and any debt or equity interest in a foreign financial institution, including a financial institution organized under the laws of a U.S. possession, and any of the following that are held for investment and not held in an account maintained by a financial institution: (1) any stock or security issued by person other than a U.S. person (including a person organized in a U.S. possession), (2) any financial instrument or contract that has an issuer or counterparty that is other than a U.S. person (including a person organized in a U.S. possession), and (3) any interest in a foreign entity. Additionally, for tax years beginning after December 12, 2014, the regulations provide that specified foreign financial assets include certain retirement and pension accounts and non-retirement savings accounts.

Proposed regulations relating to specified domestic entities apply to taxable years beginning after December 31, 2011, but have not yet been adopted as final regulations. Under the proposed regulations, “specified domestic entities” are domestic entities that are formed or used for the purposes of holding, directly or indirectly, specified foreign financial assets. Generally, specified domestic entities are certain closely held corporations and partnerships that meet passive income or passive asset tests and, with certain exceptions, domestic trusts that have a specified individual as a current beneficiary and exceed the reporting threshold. Pursuant to an IRS Notice, reporting by domestic entities of interests in specified foreign financial assets will not be required before the date specified by final regulations, which will not be earlier than taxable years beginning after December 31, 2012.

Depending on the aggregate value of your investment in specified foreign financial assets, you may be obligated to file an IRS Form 8938 under this provision if you are an individual U.S. Holder. Penalties apply to any failure to file IRS Form 8938. In the event a U.S. Holder (either a specified individual or specified domestic entity) does not file such form, the statute of limitations on the assessment and collection of U.S. federal income taxes of such U.S. Holder for the related tax year may not close before the date which is three years after the date such information

is filed. You should consult your tax advisor as to the possible application to you of this information reporting requirement and related statute of limitations tolling provision.

Backup Withholding and Information Reporting

A holder of the securities (whether a U.S. Holder or a Non-U.S. Holder) may be subject to backup withholding with respect to certain amounts paid to such holder unless it provides a correct taxpayer identification number, complies with certain certification procedures establishing that it is not a U.S. Holder or establishes proof of another applicable exemption, and otherwise complies with applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. You can claim a credit against your U.S. federal income tax liability for amounts withheld under the backup withholding rules, and amounts in excess of your liability are refundable if you provide the required information to the IRS in a timely fashion. A holder of the securities may also be subject to information reporting to the IRS with respect to certain amounts paid to such holder unless it (1) is a Non-U.S. Holder and provides a properly executed IRS Form W-8 (or other qualifying documentation) or (2) otherwise establishes a basis for exemption.

Supplemental Plan of Distribution (Conflicts of Interest)

Under the terms and subject to the conditions contained in a distribution agreement dated May 7, 2007, as amended, which we refer to as the distribution agreement, we have agreed to sell the securities to CSSU.

The distribution agreement provides that CSSU is obligated to purchase all of the securities if any are purchased.

CSSU proposes to offer the securities at the offering price set forth on the cover page of this pricing supplement and will receive underwriting discounts and commissions of $27.00 per $1,000 principal amount of securities and will forgo fees for sales to fiduciary accounts. CSSU 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. If all of the securities are not sold at the initial offering price, CSSU may change the public offering price and other selling terms.

An affiliate of Credit Suisse has paid or may pay in the future a fixed amount to broker dealers in connection with the costs of implementing systems to support these securities.

We expect to deliver the securities against payment for the securities on the Settlement Date indicated herein, which may be a date that is greater than three business days following the Trade Date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to a trade expressly agree otherwise. Accordingly, if the Settlement Date is more than three business days after the Trade Date, purchasers who wish to transact in the securities more than three business days prior to the Settlement Date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The agent for this offering, CSSU, is our affiliate. In accordance with FINRA Rule 5121, CSSU may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer. A portion of the net proceeds from the sale of the securities will be used by CSSU or one of its affiliates in connection with hedging our obligations under the securities.
