S&P 500® Index Linked Securities due June 26, 2014

General

•

The securities are designed for investors who seek a return linked to the performance of the S&P 500® Index. Investors should be willing to forgo interest and dividend payments and, if the securities have not been automatically redeemed prior to maturity and the Final Level of the Underlying is equal to or less than the Knock-In Level, be willing to lose up to 100% of their investment. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

If the securities are not automatically redeemed prior to maturity and the Final Level is greater than the Knock-In Level, investors will benefit from the greater of (i) the Fixed Payment Percentage, which is expected to be 6.0% (to be determined on the Trade Date), and (ii) the percentage change from the Initial Level to the Final Level.

•	If a Trigger Event occurs, the securities will be automatically redeemed and you will be entitled to receive a cash payment equal to the principal amount of securities you hold multiplied by the sum of 1 plus the Call Return, which is expected to be 12.70% (to be determined on the Trade Date).

•	Senior unsecured obligations of Credit Suisse AG, acting through its Nassau Branch, maturing June 26, 2014.†

•	Minimum purchase of $1,000. Minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

•	The securities are expected to price on or about June 19, 2012 (the “Trade Date”) and are expected to settle on or about June 26, 2012. Delivery of the securities in book-entry form only will be made through The Depository Trust Company.

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.

Hypothetical Redemption Amounts

The table and examples below illustrate hypothetical Redemption Amounts payable at maturity, as applicable, on a $1,000 investment in the securities for a range of scenarios. The table and examples assume that (i) the securities are not automatically redeemed prior to maturity, (ii) the Call Return is 12.70%, (iii) the Fixed Payment Percentage is 6.0% and (iv) the Knock-In Level is 75% of the Initial Level. In addition, the examples below assume that the Initial Level is 1310. The actual Call Return, Fixed Payment Percentage, Knock-In Level and Initial Level will be determined on the Trade Date. The examples are intended to illustrate hypothetical calculations of only the Redemption Amount payable at maturity and are provided for illustration purposes only. The actual Redemption Amount payable at maturity will depend on several variables, including, but not limited to whether a Knock-In Event occurs and the Final Level determined on the Valuation Date. 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 subject to an Automatic Early Redemption and there is a Knock-In Event, by how much the Final Level will decrease in comparison to the Initial Level. If a Trigger Event occurs, the securities will be automatically redeemed and the Redemption Amount per $1,000 principal amount of securities is expected to be $1,127 (to be determined on the Trade Date), and you will not be entitled to participate in any appreciation in the Underlyings above the Call Return. 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 examples have been rounded for ease of analysis.

TABLE 1: Hypothetical Redemption Amounts

Percentage Change from the Initial Level to the Final Level	Underlying Return	Redemption Amount per $1,000 Principal Amount of Securities
100.00%	100.00%	$2,000.00

−40.00%	−40.00%	$600.00
−50.00%	−50.00%	$500.00
−60.00%	−60.00%	$400.00
−70.00%	−70.00%	$300.00

−90.00%	−90.00%	$100.00
−100.00%	−100.00%	$0.00

EXAMPLES:

The following examples illustrate how the Redemption Amount is calculated.

Example 1: The Final Level is 1965, an increase of 50% from the Initial Level. Because the Final Level is greater than the Initial Level, a Knock-In Event does not occur and the Redemption Amount is determined as follows:

Underlying Return	=	the greater of (i) the Fixed Payment Percentage and (ii) (Final Level - Initial Level) / Initial Level
	=	the greater of (i) 6.0% and (ii) (1965 – 1310) / 1310
	=	the greater of (i) 6.0% and (ii) 50%
	=	50%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 1.50
	=	$1,500.00

In this example, the Underlying Return is equal to 50% and at maturity you would be entitled to receive a Redemption Amount equal to $1,500.00 per $1,000 principal amount of securities. Because the Final Level is greater than the Initial Level by more than the Fixed Payment Percentage, the Underlying Return is equal to the appreciation in the level of the Underlying from the Initial Level to the Final Level.

Example 2: The Final Level is 1375.50, an increase of 5% from the Initial Level. Because the Final Level is greater than the Initial Level, a Knock-In Event does not occur and the Redemption Amount is determined as follows:

Underlying Return	=	the greater of (i) the Fixed Payment Percentage and (ii) (Final Level - Initial Level) / Initial Level
	=	the greater of (i) 6.0% and (ii) (1375.50 – 1310) / 1310
	=	the greater of (i) 6.0% and (ii) 5%
	=	6.0%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 1.06
	=	$1,060.00

In this example, the Underlying Return is equal to 6.0% and at maturity you would be entitled to receive a Redemption Amount equal to $1,060.00 per $1,000 principal amount of securities. Because the Final Level is greater than the Initial Level by less than the Fixed Payment Percentage, the Underlying Return is equal to the Fixed Payment Percentage. In this example you will receive more than the appreciation in the level of the Underlying during the term of the securities.

Example 3: The Final Level is 1179, a decrease of 10% from the Initial Level. Because the Final Level is less than the Initial Level and a Knock-In Event does not occur, the Redemption Amount is determined as follows:

Underlying Return	=	the greater of (i) the Fixed Payment Percentage and (ii) (Final Level - Initial Level) / Initial Level
	=	the greater of (i) 6.0% and (ii) (1179 – 1310) / 1310
	=	the greater of (i) 6.0% and (ii) −10%
	=	6.0%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 1.06
	=	$1,060.00

In this example, the Underlying Return is equal to 6.0% and at maturity you would be entitled to receive a Redemption Amount equal to $1,060.00 per $1,000 principal amount of securities. Because the Final Level is less than the Initial Level and a Knock-In Event does not occur, the Underlying Return is equal to the Fixed Payment Percentage. In this example you will receive more than the principal amount of securities.

Example 4: The Final Level is 786, a decrease of 40% from the Initial Level. Because the Final Level is less than the Knock-In Level, a Knock-In Event occurs and the Redemption Amount is determined as follows:

Underlying Return	=	(Final Level - Initial Level) / Initial Level
	=	(786 – 1310) / 1310
	=	−40%
Redemption Amount	=	$1,000 × (1 + Underlying Return)
	=	$1,000 × 0.60
	=	$600.00

In this example, at maturity you would be entitled to receive a Redemption Amount equal to $600.00 per $1,000 principal amount of securities because the Final Level is less than the Knock-In Level. In these circumstances, you will participate in any depreciation in the level of the Underlying from the Initial Level to the Final Level.

Selected Risk Considerations

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

•

YOUR INVESTMENT IN THE SECURITIES MAY RESULT IN A LOSS — The securities do not guarantee any return of your principal amount. You could lose up to $1,000 per $1,000 principal amount of securities. If a Knock-In Event occurs, you will lose 1% of your principal for each 1% decline in the Final Level as compared to the Initial Level. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

IF THE SECURITIES ARE SUBJECT TO AUTOMATIC EARLY REDEMPTION, YOUR GAIN ON THE SECURITIES WILL BE LIMITED TO THE CALL RETURN — If the securities are subject to Automatic Early Redemption, your gain will be limited to the Call Return, which is expected to be 12.70% (to be determined on the Trade Date), regardless of the appreciation in the Underlying, which may be significant. In this case, you will lose the opportunity to participate in the appreciation of the Underlying, if any, during the term of the securities and you may receive less than if the securities have been held to maturity. If the securities are redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that yield as much as the securities.

•

THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE — Although the return on the securities will be based on the performance of the Underlying, the payment of any amount due on the securities 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.

•

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 Underlying. 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.

•

THE RETURN ON THE SECURITIES WILL BE AFFECTED BY THE KNOCK-IN LEVEL AND THE OCCURRENCE OF A KNOCK-IN EVENT — The return on the securities will be affected by the Knock-In Level and whether a Knock-In Event occurs. If the securities are not automatically redeemed prior to maturity and the Final Level of the Underlying is equal to or less than the Knock-In Level, a Knock-In Event will occur. In this case, you will receive less than your principal amount at maturity and you could lose your entire investment.

•

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 — In addition to the level of the Underlying on any trading day, 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 expected volatility of the Underlying;

the time to maturity of the securities;

the dividend rate on the equity securities comprising the Underlying;

interest and yield rates in the market generally;

investors’ expectations with respect to the rate of inflation;

the occurrence of certain events to the shares of the Underlying that may or may not require an anti-dilution adjustment;

geopolitical conditions and a variety of economic, financial, political, regulatory or judicial events that affect the components comprising the Underlying or markets generally and which may affect the level of the Underlying;

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 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 equity securities that comprise the Underlying.

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 Valuation Date) could adversely affect the value of the Underlying and, as a result, could decrease the amount you may receive on the securities at maturity. For further information, please refer to “Supplemental Use of Proceeds and Hedging” in the accompanying product supplement.

Historical Information

The following graph sets forth the historical performance of the S&P 500® Index based on the closing levels of the Underlying from January 1, 2007 through June 11, 2012. The closing level of the Underlying on June 11, 2012 was 1308.93. We obtained the closing levels below from Bloomberg, without independent verification. We make no representation or warranty as to the accuracy or completeness of the information obtained from Bloomberg.

The historical levels of the Underlying should not be taken as an indication of future performance, and no assurance can be given as to the closing level of the Underlying on any trading day during the term of the securities, including on the Valuation Date. We cannot give you assurance that the performance of the Underlying will result in any return of your investment. Any payment on the securities is subject to our ability to pay our obligations as they become due.

For additional information about the S&P 500® Index, see the information set forth under “The Reference Indices—The S&P Indices—The S&P 500® Index” in the accompanying underlying supplement.

Market Disruption Events

If the Review Date is not an underlying business day or if a market disruption event exists in respect of the Underlying on such date, then the Review Date will be postponed in respect of such Underlying to the first succeeding underlying business day for the Underlying on which the calculation agent determines that no market disruption event exists in respect of the Underlying, unless the calculation agent determines that a market disruption event exists in respect of the Underlying on each of the five underlying business days for the Underlying immediately following the scheduled Review Date. In that case, (a) the fifth succeeding underlying business day for the Underlying following the scheduled Review Date will be deemed to be such Review Date for the Underlying, notwithstanding the market disruption event in respect of the Underlying, and (b) the calculation agent will determine the closing level for the Underlying on that deemed Review Date in accordance with the formula for and method of calculating such Underlying last in effect prior to the commencement of the market disruption event in respect of the Underlying using exchange-traded prices on the relevant exchanges (as determined by the calculation agent in its sole discretion) or, if trading in any component comprising the Underlying has been materially suspended or materially limited, the calculation agent’s good faith estimate of the prices that would have prevailed on the relevant exchanges (as determined by the calculation agent in its sole discretion) but for the suspension or limitation, as of the valuation time on that deemed Review Date, of each component comprising the Underlying (subject to the provisions described under “—Changes to the calculation of a reference index” in the accompanying product supplement).

Material U.S. Federal Income Tax Considerations

The following discussion summarizes material U.S. federal income tax consequences of owning and disposing of securities that may be relevant to holders of 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 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 or will be sought as to the U.S. federal income tax consequences of the ownership and disposition of 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 securities, including the application of federal, state, local and foreign income and other tax laws based on your particular facts and circumstances.

IRS CIRCULAR 230 REQUIRES THAT WE INFORM YOU THAT ANY TAX STATEMENT HEREIN REGARDING ANY U.S. FEDERAL TAX IS NOT INTENDED OR WRITTEN TO BE USED, AND CANNOT BE USED, BY ANY TAXPAYER FOR THE PURPOSE OF AVOIDING ANY PENALTIES. ANY SUCH STATEMENT HEREIN WAS WRITTEN TO SUPPORT THE MARKETING OR PROMOTION OF THE TRANSACTION(S) OR MATTER(S) TO WHICH THE STATEMENT RELATES. A PROSPECTIVE INVESTOR (INCLUDING A TAX-EXEMPT INVESTOR) IN THE SECURITIES SHOULD CONSULT ITS OWN TAX ADVISOR IN DETERMINING THE TAX CONSEQUENCES OF AN INVESTMENT IN THE SECURITIES, INCLUDING THE APPLICATION OF STATE, LOCAL OR OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

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 a prepaid financial contract, with respect to the Underlying that is 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 your securities for all tax purposes in accordance with such characterization. In light of the fact that we agree to treat the securities as a prepaid financial contract, 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 above. 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, or the comparable yield. The characterization of 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 security 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, if the security provides for the payment of the redemption amount in cash based on the return of the underlying, 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 underlying, 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 should 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 should 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 reference 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, 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.

Securities Held Through Foreign Accounts

Under the “Hiring Incentives to Restore Employment Act” (the “Act”) and recently proposed regulations, a 30% withholding tax is imposed on “withholdable payments” and certain “passthru payments” made to foreign financial institutions (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. “Withholdable payments” include (1) payments of interest (including original issue discount), dividends, and other items 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” generally are certain payments attributable to withholdable payments. The Act 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%. We will treat payments on the securities as withholdable payments for these purposes.

Withholding under the Act described above 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 proposed regulations, the Act’s withholding regime generally will apply to (i) withholdable payments (other than gross proceeds of the type described above) made after December 31, 2013, (ii) payments of gross proceeds of the type described above with respect to a sale or disposition occurring after December 31, 2014, and (iii) passthru payments made after December 31, 2016. Additionally, the provisions of the Act discussed above generally will not apply to obligations (other than an instrument that is treated as equity for U.S. tax purposes or that lacks a stated expiration or term) that are outstanding on January 1, 2013. Thus, if you hold your securities through a foreign financial institution or foreign corporation or trust, a portion of any of your payments made after December 31, 2013 may be subject to 30% withholding.

Non-U.S. Holders Generally

In the case of a holder of the securities that is not a U.S. Holder and has no connection with the United States other than holding its securities (a “Non-U.S. Holder”), payments made with respect to the 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 should consult their tax advisors regarding the possibility that any portion of the return with respect to the securities could be characterized as dividend income and be subject to U.S. withholding tax.

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 Act and recently proposed and temporary regulations treat a “dividend equivalent” payment as a dividend from sources within the United States. Under the Act, 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” 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). Proposed regulations provide criteria for determining whether a notional principal contract will be a specified notional principal contract, effective for payments made after December 31, 2012.

Proposed regulations address whether a payment is a dividend equivalent. The proposed regulations provide that an equity-linked instrument that provides for a payment that is a substantially similar payment is treated as a notional principal contract for these purposes. An equity-linked instrument is a financial instrument or combination of financial instruments that references one or more underlying securities to determine its value, including a futures contract, forward contract, option, or other contractual arrangement. Although it is not certain, an equity-linked instrument could include instruments treated as indebtedness for U.S. federal income tax purposes. The proposed regulations consider any payment, including the payment of the purchase price or an adjustment to the purchase price, to be a substantially similar payment (and, therefore, a dividend equivalent payment) if made pursuant to an equity-linked instrument that is contingent upon or determined by reference to a dividend (including payments pursuant to a redemption of stock that gives rise to a dividend) from sources within the United States. The rules for equity-linked instruments under the proposed regulations will be effective for payments made after the rules are finalized. Where the securities reference an interest in a fixed basket of securities or a “customized index,” each security or component of such basket or customized index is treated as an underlying security in a separate notional principal contract for purposes of determining whether such notional principal contract is a specified notional principal contract or an amount received is a substantially similar payment.

We will treat any portion of a payment on the securities 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. Investors should consult their tax advisors regarding whether payments on the securities constitute dividend equivalent payments.

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

The securities may be subject to U.S. federal estate tax if an individual Non-U.S. Holder holds the securities 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 on Certain Financial Transactions

On December 7, 2007, the IRS and the Treasury Department issued Notice 2008-2, in which they 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.

Information Reporting Regarding Specified Foreign Financial Assets

The Act and temporary and proposed regulations 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 new 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. The proposed regulations relating to specified domestic entities apply to taxable years beginning after December 31, 2011. 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. Specified foreign financial assets include any depository or custodial account held at a foreign financial institution; any debt or equity interest in a foreign financial institution if such interest is not regularly traded on an established securities market; and, if not held at a financial institution, (i) any stock or security issued by a non-U.S. person, (ii) any financial instrument or contract held for investment where the issuer or counterparty is a non-U.S. person, and (iii) any interest in an entity which is a non-U.S. person.

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. Specified domestic entities are not required to file Form 8938 until the proposed regulations are final. Penalties apply to any failure to file IRS Form 8938. Additionally, 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 own 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 may receive underwriting discounts and commissions of up to $21.00 per $1,000 principal amount of securities. 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.

In addition, Credit Suisse International, an affiliate of Credit Suisse, may pay referral fees of up to $2.50 per $1,000 principal amount of securities in connection with the distribution of the securities. 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 that delivery of the securities will be made against payment for the securities on or about June 26, 2012, which will be the fifth business day following the Trade Date for the securities (this settlement cycle being referred to as T+5). Under Rule 15c6-1 under 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 that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the securities on the Trade Date or the following business day will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

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.
