Summary

The Autocallable Market-Linked Step Up Notes Linked to the Russell 2000® Index, due February , 2018 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other governmental agency of the United States, Switzerland or any other jurisdiction and are not secured by collateral. The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of Credit Suisse. The notes will be automatically called at the applicable Call Amount if the Observation Level of the Market Measure, which is the Russell 2000® Index (the “Index”), is equal to or greater than the Call Level on the relevant Observation Date. If not called, at maturity, the notes provide you with a Step Up Payment if the Ending Value of the Index is equal to or greater than its Starting Value, but is not greater than the Step Up Value. If the Ending Value is greater than the Step Up Value, you will participate on a 1-for-1 basis in the increase in the level of the Index above the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Call Premiums and the Call Amounts) are based on the rate we are currently paying to borrow funds through the issuance of market-linked notes (our “internal funding rate”) and the economic terms of certain related hedging arrangements. Our internal funding rate for market-linked notes is typically lower than a rate reflecting the yield on our conventional debt securities of similar maturity in the secondary market (our “secondary market credit rate”). This difference in borrowing rate, as well as the underwriting discount and the hedging related charge described below, will reduce the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. These costs will be effectively borne by you as an investor in the notes, and will be retained by us and MLPF&S or any of our respective affiliates in connection with our structuring and offering of the notes. Due to these factors, the public offering price you pay to purchase the notes will be greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This range of estimated values reflects terms that are not yet fixed and was determined based on our valuation of the theoretical components of the notes in accordance with our pricing models. These include a theoretical bond component valued using our internal funding rate, and theoretical individual option components valued using mid-market pricing. You will not have any interest in, or rights to, the theoretical components we use to determine the estimated value of the notes. The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes. The initial estimated value of the notes calculated on the pricing date will be set forth in the final term sheet made available to investors in the notes. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-12.

Hypothetical Payout Profile at Maturity

The below graph is based on hypothetical numbers and values. These hypothetical values show a payout profile at maturity, which would only apply if the notes are not called on any Observation Date.

Market-Linked Step Up Notes

This graph reflects the returns on the notes, based on the Threshold Value of 100% of the Starting Value, the Step Up Payment of $2.50 per unit, and the Step Up Value of 125% of the Starting Value. The green line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the stocks included in the Index, excluding dividends.

This graph has been prepared for purposes of illustration only.

See below table for a further illustration of the range of hypothetical payments at maturity.

Hypothetical Payments at Maturity

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes, assuming the notes are not called on any Observation Date. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value, Threshold Value, Ending Value, Step Up Value, whether the notes are called on an Observation Date, and term of your investment.

The following table is based on a Starting Value of 100, a Threshold Value of 100, a Step Up Value of 125 and the Step Up Payment of $2.50 per unit. It illustrates the effect of a range of Ending Values on the Redemption Amount per unit of the notes and the total rate of return to holders of the notes. The following examples do not take into account any tax consequences from investing in the notes.

This amount represents the sum of the principal amount and the Step Up Payment of $2.50.

(4)

This is the hypothetical Step Up Value.

For recent actual levels of the Market Measure, see “The Index” section below. The Index is a price return index and as such the Ending Value will not include any income generated by dividends paid on the stocks included in the Index, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

Risk Factors

There are important differences between the notes and a conventional debt security. An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-7 of product supplement EQUITY INDICES SUN-2 identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

If the notes are not automatically called, depending on the performance of the Index as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

If the notes are called, your investment return is limited to the return represented by the applicable Call Premium.

Your investment return may be less than a comparable investment directly in the stocks included in the Index.

The initial estimated value of the notes is an estimate only, determined as of a particular point in time by reference to our proprietary pricing models. These pricing models consider certain factors, such as our internal funding rate on the pricing date, interest rates, volatility and time to maturity of the notes, and they rely in part on certain assumptions about future events, which may prove to be incorrect. Because our 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 us (even among issuers with similar creditworthiness), our estimated value may not be comparable to estimated values of similar notes of other issuers.

Our internal funding rate for market-linked notes is typically lower than our secondary market credit rates, as further described in “Structuring the Notes” on page TS-12. Because we use our internal funding rate to determine the value of the theoretical bond component, if on the pricing date our internal funding rate is lower than our secondary market credit rates, the initial estimated value of the notes will be greater than if we had used our secondary market credit rates in valuing the notes.

The public offering price you pay for the notes will exceed the initial estimated value. This is due to, among other transaction costs, the inclusion in the public offering price of the underwriting discount and the hedging related charge, as further described in “Structuring the Notes” on page TS-12.

Assuming no change in market conditions or other relevant factors after the pricing date, the market value of your notes may be lower than the price you paid for them and lower than the initial estimated value. This is due to, among other things, the inclusion in the public offering price of the underwriting discount and the hedging related charge and the internal funding rate we used in pricing the notes, as further described in “Structuring the Notes” on page TS-12. These factors, together with customary bid ask spreads, other transaction costs and various credit, market and economic factors over the term of the notes, including changes in the level of the Index, are expected to reduce the price at which you may be able to sell the notes in any secondary market and will affect the value of the notes in complex and unpredictable ways.

A trading market is not expected to develop for the notes. Neither we nor MLPF&S is obligated to make a market for, or to repurchase, the notes. The initial estimated value does not represent a minimum or maximum price at which we, MLPF&S or any of our affiliates would be willing to purchase your notes in any secondary market (if any exists) at any time. MLPF&S has advised us that any repurchases by them or their affiliates will be made at prices determined by reference to their pricing models and at their discretion, and these prices will include MLPF&S’s trading commissions and mark-ups. If you sell your notes to a dealer other than MLPF&S in a secondary market transaction, the dealer may impose its own discount or commission. MLPF&S has also advised us that, at its discretion and for your benefit, assuming no changes in market conditions from the pricing date, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes for a short initial period after the issuance of the notes. That higher price reflects costs that were included in the public offering price of the notes, and that higher price may also be initially used for account statements or otherwise. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

Our business, hedging and trading activities, and those of MLPF&S and our respective affiliates (including trading in shares of companies included in the Index), and any hedging and trading activities we, MLPF&S or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

The Index sponsor may adjust the Index in a way that affects its level, and has no obligation to consider your interests.

You will have no rights of a holder of the securities represented by the Index, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

While we, MLPF&S or our respective affiliates may from time to time own securities of companies included in the Index, we, MLPF&S and our respective affiliates do not control any company included in the Index, and are not responsible for any disclosure made by any other company.

There may be potential conflicts of interest involving the calculation agent. We have the right to appoint and remove the calculation agent.

The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes. See “Material U.S. Federal Income Tax Considerations” below and “Material U.S. Federal Income Tax Consequences” beginning on page PS-29 of product supplement EQUITY INDICES SUN-2.

The Index

All disclosures contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation, and changes in its components, have been derived from publicly available sources. The information reflects the policies of, and is subject to change by, Russell Investments (“Russell,” or the “Index sponsor”). The Index sponsor, which licenses the copyright and all other rights to the Index, has no obligation to continue to publish, and may discontinue publication of, the Index. The consequences of the Index sponsor discontinuing publication of the Index are discussed in the section entitled “Description of the Notes - Discontinuance of an Index” beginning on page PS-22 of product supplement EQUITY INDICES SUN-2. None of us, the calculation agent, or MLPF&S accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

The Index is intended to track the performance of the small-cap segment of the U.S. equity market. The Index is reconstituted annually and eligible initial public offerings (“IPOs”) are added to the Index at the end of each calendar quarter. The Index is a subset of the Russell 3000E™ Index, which contains the largest 4,000 companies incorporated in the U.S. and its territories and represents approximately 99% of the U.S. equity market. The Index measures the composite price performance of stocks of approximately 2,000 U.S. companies. As of December 31, 2014, the largest five sectors represented by the Index were Financial Services, Technology, Health Care, Consumer Discretionary, and Producer Durables. Real-time dissemination of the value of the Index by Reuters began on December 31, 1986. The Index was developed by Russell and is calculated, maintained and published by Russell. The Index is reported by Bloomberg under ticker symbol “RTY”.

Methodology for the Russell U.S. Indices

Companies must be classified as U.S. companies under Russell’s country-assignment methodology in order to be included in the Russell U.S. indices. If a company is incorporated, has a stated headquarters location, and trades in the same country (American Depositary Receipts and American Depositary Shares are not eligible), the company is assigned to the equity market of its country of incorporation. If any of the three do not match, Russell then defines three Home Country Indicators (“HCI”): country of Incorporation, country of Headquarters, and country of the most liquid exchange as defined by two-year average daily dollar trading volume (“ADDTV”) from all exchanges within a country. Using the HCIs, Russell cross-compares the primary location of the company’s assets with the three HCIs. If the primary location of the company’s assets matches any of the HCIs, then the company is assigned to its primary asset location. If there is insufficient information to determine the country in which the company’s assets are primarily located, Russell will use the primary country from which the company’s revenues are primarily derived for the comparison with the three HCIs in a similar manner. If conclusive country details cannot be derived from assets or revenue, Russell assigns the company to the country where its headquarters are located unless the country is a Benefit Driven Incorporation (BDI) country; in which case, the company will be assigned to the country of its most liquid stock exchange. Russell lists the following countries as BDIs: Anguilla, Antigua and Barbuda, Bahamas, Barbados, Belize, Bermuda, Bonaire, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Curacao, Faroe Islands, Gibraltar, Isle of Man, Liberia, Marshall Islands, Panama, Saba, Sint Eustatius, Sint Maarten, and Turks and Caicos Islands. For any companies incorporated or headquartered in a U.S. territory, including countries such as Puerto Rico, Guam, and U.S. Virgin Islands, a U.S. HCI is assigned.

Preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights, and trust receipts are not eligible for inclusion in the Russell U.S. Indices. Royalty trusts, limited liability companies, closed-end investment companies (business development companies are eligible), blank check companies, special-purpose acquisition companies, and limited partnerships are also not eligible for inclusion in the Russell U.S. Indices. Bulletin board, pink-sheets, and over-the-counter (“OTC”) traded securities are not eligible for inclusion. Stocks must trade at or above $1.00 on their primary exchange on the last trading day in May to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing member’s closing price is less than $1.00 on the last day of May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the month of May is equal to or greater than $1.00. Initial public offerings must have a closing price at or above $1.00 on the last day of their eligibility period in order to qualify for index inclusion. If a stock, new or existing, does not have a closing price at or above $1.00 (on its primary exchange) on the last trading day in May, but does have a closing price at or above $1.00 on another major U.S. exchange, that stock will be eligible for inclusion. Companies with a total market capitalization of less than $30 million are not eligible for the Index. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible for the Index.

The primary criterion used to determine the initial list of securities eligible for the Russell U.S. Indices is total market capitalization, which is determined by multiplying total outstanding shares by the market price as of the last trading day in May for those securities being considered at annual reconstitution. IPO eligibility is determined each quarter.

Common stock, non-restricted exchangeable shares that may be exchanged at any time at the holder’s option on a one-for-one basis for common stock, and partnership units/membership interests (in certain cases, described below) are used to determine market capitalization for a company. Russell includes membership or partnership units/interests as part of total market capitalization when the company in question is merely a holding company of underlying entity that issues membership or partnership units/interests and these units are the company’s sole assets. If multiple share classes of common stock exist, they are combined. In cases where the common stock share classes act independently of each other, each class is considered for inclusion separately. On the last trading day of May of each year, all eligible securities are ranked by their total market capitalization. Reconstitution occurs on the last Friday in June. However, at times this date precedes a long U.S. holiday weekend, when liquidity is low. In order to ensure proper liquidity in the markets, when the last Friday in June is the 28th, 29th or 30th, reconstitution will occur on the preceding Friday. In addition, Russell

Autocallable Market-Linked Step Up Notes

TS-8

Autocallable Market-Linked Step Up Notes

Linked to the Russell 2000® Index, due February , 2018

adds initial public offerings to the Index on a quarterly basis based on market capitalization guidelines established during the most recent reconstitution.

Once the market capitalization for each security is determined by use of total shares and price, each security is placed in the appropriate Russell market capitalization based index. The largest 4,000 securities become members of the Russell 3000E™ Index.

After the initial market capitalization breakpoints are determined by the ranges listed above, new members are assigned on the basis of the breakpoints and existing members are reviewed to determine if they fall within a cumulative 5% market capitalization range around these new market capitalization breakpoints. If an existing member’s market capitalization falls within this cumulative 5% of the market capitalization breakpoint, it will remain in its current index rather than be moved to a different market capitalization–based Russell index.

Capitalization Adjustments

After membership is determined, a security’s shares are adjusted to include only those shares available to the public, which is often referred to as “free float.” The purpose of this adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set. Stocks are weighted in the Russell U.S. Indices by their available market capitalization, which is calculated by multiplying the primary closing price by the available shares.

The following types of shares are considered unavailable for purchase and removed from total market capitalization to arrive at free float or available market capitalization:

ESOP or LESOP shares that comprise 10% or more of the shares outstanding are adjusted;

Cross ownership by another Russell 3000E™ Index or Russell Global® Index member: Shares held by another member of a Russell index (including Russell global indices) is considered cross ownership, and all shares will be adjusted regardless of percentage held;

Large corporate and private holdings: Shares held by another listed company (non-member) or by private individuals will be adjusted if they are greater than 10% of shares outstanding. Not included in this class are institutional holdings, including investment companies, partnerships, insurance companies, mutual funds, banks or venture capital firms;

Unlisted share classes: Classes of common stock that are not traded on a U.S. exchange are adjusted;

IPO lock-ups: Shares locked up during an IPO that are not available to the public and will be excluded from the market value at the time the IPO enters the index; and

Government Holdings:

Direct government holders: Those holdings listed as “government of” are considered unavailable and will be removed entirely from available shares.

Indirect government holders: Shares held by government investment boards and/or investment arms will be treated similar to large private holdings and removed if the holding is greater than 10%.

Government pensions: Any holding by a government pension plan is considered institutional holdings and will not be removed from available shares.

Corporate Actions Affecting a Russell U.S. Index

Depending upon the time an action is determined to be final, Russell will either (1) apply the action before the open on the ex-date, or (2) apply the action providing appropriate notice, referred to as “delayed action.” The following describes the treatment of the most common corporate actions within the Russell Indexes.

“No Replacement” Rule: Securities that leave a Russell U.S. Index for any reason (e.g., mergers, acquisitions or other similar corporate activity) are not replaced. Thus, the number of securities in a Russell U.S. Index over the year will fluctuate according to corporate activity.

Mergers and Acquisitions: Mergers and Acquisitions (M&A) result in changes to the membership and to the weighting of members within a Russell U.S. Index. M&A activity is applied to a Russell U.S. Index after the action is determined to be final. If both companies involved are included in the Russell 3000E™ Index or the Russell Global Index, the acquired company is deleted and its market capitalization is moved to the acquiring company’s stock, according to the merger terms. If only one company is included in the Russell 3000E™ Index, there may be two forms of merger or acquisition: if the acquiring company is a member, the acquiring company’s shares will be adjusted at month end, and if the acquiring company is not a member, the acquired company will be deleted after the action is determined as final.

Reverse Mergers: When a Russell 3000 Index member is acquired or merged with a private, non-publicly-traded company or OTC company, Russell will review the action to determine whether it is considered a reverse merger. If it is determined that the action is a reverse merger, the newly formed entity will be placed in the appropriate market capitalization index after the close of the day following the completion of the merger and the acquired company will be simultaneously removed from the current index.

Reincorporations: Members that are reincorporated to another country are analyzed for country assignment the following year during reconstitution, as long as they continue to trade in the U.S. Companies that reincorporate and are no longer trade in the U.S. are immediately deleted from the U.S. indexes and placed in the appropriate country within the Russell Global Index.

Reclassification: The class of a member’s securities included in the Index will not be assessed or changed outside of a reconstitution period unless the existing class ceases to exist.

Rights offerings: Russell will not apply poison pill rights or entitlements that give shareholders the right to purchase ineligible securities such as convertible debt. Russell will only adjust the Index to account for a right if the subscription price of the right is at a discount to the market price of the stock. Provided Russell is aware of the rights offer prior to the ex-date, a price adjustment will be applied before the open on the ex-date to account for the value of the rights, and shares increased according to the terms of the offering. If Russell is unable to provide prior notice, the price adjustment and share increase will be delayed until appropriate notice is given. In these circumstances the price of the stock involved is adjusted to delay the performance due to the rights issue.

Changes to shares outstanding: Changes to shares outstanding due to buybacks (including Dutch auctions), secondary offerings, merger activity with a non-index member and other potential changes are updated at the end of the month in which the change is reflected in vendor-supplied updates and are verified by Russell by use of an SEC filing. For a change in shares to occur, the cumulative change to available shares must be greater than 5%. These share changes are communicated three trading days prior to month-end and include shares provided by the vendor and verified by Russell four days prior to month-end. The float factor determined at reconstitution is applied to the new shares issued or bought back.

Spin-offs: Spin-off companies are added to the parent company’s index and capitalization tier of membership, if the spin-off company is large enough. To be eligible, the spun-off company’s total market capitalization must be greater than the market adjusted total market capitalization of the smallest security in the Russell 3000E™ Index at the latest reconstitution.

Tender offers: In the case of a cash tender offer, the target company will be removed from the index when: the offer period completes (initial, extension or subsequent); shareholders have validly tendered, not withdrawn, the shares have been accepted for payment; all regulatory requirements have been fulfilled; and the acquiring company is able to finalize the acquisition via short-form merger, top-up option or other compulsory mechanism. If the requirements have been fulfilled except where the acquirer is unable to finalize the acquisition through a compulsory mechanism, an adjustment will be applied to the target company’s float-adjusted shares if they have decreased by 30% or more, and the tender offer has fully complete and closed. The adjustment will occur on a date pre-announced by Russell.

Delisting: Only companies listed on U.S. exchanges are included in the Russell U.S. Indices. Therefore, when a company is delisted from a U.S. exchange and moved to OTC, the company is removed from the Russell U.S. Index either at the close of the current day or the following day.

Bankruptcies and Voluntary Liquidations: Companies filing for Chapter 7 bankruptcy or that have filed a liquidation plan will be removed from the Russell U.S. Indices at the time of filing. Companies filing for Chapter 11 reorganization bankruptcy will remain members of the Russell U.S. Indices, unless the companies are delisted from the primary exchange and then normal delisting rules will apply.

Change of Company Structure: In the event a company changes its corporate designation from that of a Business Development Company, Russell will remove the member as ineligible for index inclusion and provide two-days’ notice of its removal.

Stock Distributions: Stock distributions can take two forms: (1) a stated amount of stock distributed on the ex-date, or (2) an undetermined amount of stock based on earnings and profits to be distributed at a future date. In both cases, a price adjustment is done on the ex-date of the distribution. Shares are increased on the ex-date for category (1) and on the pay-date for category (2).

Halted securities: When a stock’s trading has been halted, Russell holds the security at its most recent closing price until trading is resumed or is officially delisted.

In addition, Russell will review stocks in two categories for removal: (1) stocks halted due to financial difficulty/debt or cash flow issues for a period longer than 40 calendar days or (2) those stocks suspended due to exchange listing rules or legal regulatory issues longer than one calendar quarter. Determination for removal will be made on a case-by-case basis and based upon reasonable likelihood of trade resumption and likelihood of residual value returned to equity holders. Should removal be deemed appropriate, announcement will be made with monthly share changes and removed on month-end at zero value (for system purposes the actual value used is .0001, in local currency).

Stocks that are scheduled for removal but suspended or not trading through reconstitution due to low liquidity or those that are suspended by the exchange or other governing body due to liquidity issues will be monitored for trade resumption. Once trading resumes, these securities will be removed from the index with announcement as usual. Securities will be removed using the primary exchange close price.

Supplement to the Plan of Distribution

Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than three business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the notes occurs more than three business days from the pricing date, purchasers who wish to trade the notes more than three business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S acting as a principal in effecting the transaction for your account.

MLPF&S will not receive an underwriting discount for notes sold to certain fee-based trusts and fee-based discretionary accounts managed by U.S. Trust operating through Bank of America, N.A.

MLPF&S has advised us as follows: They or their affiliates may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices determined by reference to their pricing models and at their discretion, and these prices will include MLPF&S’s trading commissions and mark-ups. MLPF&S may act as principal or agent in these market-making transactions; however, it is not obligated to engage in any such transactions. MLPF&S has informed us that at MLPF&S’s discretion and for your benefit, assuming no changes in market conditions from the pricing date, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes for a short initial period after the issuance of the notes. Any price offered by MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Index and the remaining term of the notes. However, none of us, MLPF&S, or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S, or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

MLPF&S has informed us that, as of the date of this term sheet, it expects that if you hold your notes in a MLPF&S account, the value of the notes shown on your account statement will be based on MLPF&S’s estimate of the value of the notes if MLPF&S or another of its affiliates were to make a market in the notes, which it is not obligated to do; and that estimate will be based upon the price that MLPF&S may pay for the notes in light of then-prevailing market conditions and other considerations, as mentioned above, and will include transaction costs. Any such price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding Credit Suisse or for any purpose other than that described in the immediately preceding sentence.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Index. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. In addition, because market-linked notes result in increased operational, funding and liability management costs to us, the internal funding rate we use in pricing market-linked notes is typically lower than a rate reflecting the yield on our conventional debt securities of similar maturity in the secondary market. Because we use our internal funding rate to determine the value of the theoretical bond component, if on the pricing date our internal funding rate is lower than our secondary market credit rates, the initial estimated value of the notes will be higher than if the initial estimated value was based our secondary market credit rates.

Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with MLPF&S or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including MLPF&S and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Index, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

MLPF&S has advised us that the hedging arrangements will include a hedging related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to MLPF&S from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by MLPF&S or any third party hedge providers.

Material U.S. Federal Income Tax Considerations

The following discussion is a brief summary of material U.S. federal income tax consequences relating to an investment in the notes. The following summary is not complete and is qualified and supplemented by, or in some cases supplements, the discussion under the section entitled “Material U.S. Federal Income Tax Consequences” beginning on page PS-29 of product supplement EQUITY INDICES SUN-2, which you should carefully review prior to investing in the notes.

There are no statutory provisions, regulations, published rulings, or judicial decisions addressing the characterization for U.S. federal income tax purposes of the notes or securities with terms that are substantially the same as those of the notes. Thus, the characterization of the notes is not certain. In the absence of an administrative or judicial ruling to the contrary and pursuant to the terms of the notes, you agree with us to treat the notes, for U.S. federal income tax purposes, as prepaid financial contracts, with respect to the Market Measure, that are eligible for open transaction treatment. The balance of this discussion assumes that the notes will be treated as prepaid financial contracts. You should be aware that such characterization of the notes is not certain, nor is it binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Thus, it is possible that the IRS would seek to characterize your notes in a manner that results in tax consequences to you that are different from those described below or in the accompanying product supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the notes 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 the notes for U.S. federal income tax purposes.

If the notes are treated as prepaid financial contracts, a U.S. Holder (as defined in the accompanying product supplement) should generally recognize gain or loss upon the sale, exchange or maturity of its notes in an amount equal to the difference between the amount realized at such time and the U.S. Holder’s tax basis in its notes (generally the amount paid for the notes). Such gain or loss generally should be long-term capital gain or loss if the notes have been held for more than one year. For notes with a term of one year or less, such gain or loss will be short-term capital gain or loss.

Notes Held Through Foreign Entities

Pursuant to recently finalized regulations and IRS Notice 2013-43, and subject to certain exceptions, FATCA’s withholding regime generally will apply to (i) withholdable payments (other than certain gross proceeds) made after June 30, 2014 (other than certain payments made with respect to a “preexisting obligation,” as defined in the regulations); (ii) payments of certain gross proceeds 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.

Substitute Dividend and Dividend Equivalent Payments

In Notice 2014-14, the IRS stated that it intends to limit specified ELIs, as defined in the proposed regulations under Code section 871(m), to ELIs issued on or after 90 days after the date the proposed regulations are finalized.

Proposed Legislation on Certain Financial Transactions

On February 26, 2014, the Chairman of the House Ways and Means Committee released in draft form certain proposed legislation relating to financial instruments. If enacted as proposed, the effect of that legislation generally would be to require instruments such as the notes acquired after December 31, 2014, or any notes held after December 31, 2019, to be marked to market on an annual basis with all gains and losses to be treated as ordinary, subject to certain exceptions. You are urged to consult your tax advisor regarding the draft legislation and its possible impact on you.

You should consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.
