Summary

The Strategic Accelerated Redemption Securities^® Linked to the NYSE Arca Gold Miners Index, due December , 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 closing level of the Market Measure, which is the NYSE Arca Gold Miners Index (the “Index”), on any Observation Date is equal to or greater than the Starting Value. If your notes are not called, 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 Amounts and Call Premiums) 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-14.

Investor Considerations

You may wish to consider an investment in the notes if:

The notes may not be an appropriate investment for you if:

§  You anticipate that the closing level of the Index on any of the Observation Dates will be equal to or greater than the Starting Value and, in that case, you accept an early exit from your investment. §  You accept that the return on the notes will be limited to the return represented by the applicable Call Premium even if the percentage change in the level of the Index is significantly greater than the applicable Call Premium. §  If the notes are not called, you accept that your investment will result in a loss, which could be significant, if the Ending Value is below the Threshold Value. §  You are willing to forgo the interest payments that are paid on traditional interest bearing debt securities. §  You are willing to forgo dividends or other benefits of owning the stocks included in the Index. §  You are willing to accept a limited or no market for sales prior to maturity, and understand that the market prices for the notes, if any, will be affected by various factors, including our actual and perceived creditworthiness, our internal funding rate and fees and charges on the notes. §  You are willing to assume our credit risk, as issuer of the notes, for all payments under the notes, including the Call Amounts and the Redemption Amount.

§  You wish to make an investment that cannot be automatically called prior to maturity. §  You believe that the level of the Index will decrease from the Starting Value to the Ending Value. §  You anticipate that the Observation Level will be less than the Call Level on each Observation Date. §  You seek an uncapped return on your investment §  You seek principal repayment or preservation of capital. §  You seek interest payments or other current income on your investment. §  You want to receive dividends or other distributions paid on the stocks included in the Index. §  You seek an investment for which there will be a liquid secondary market. §  You are unwilling or are unable to take market risk on the notes or to take our credit risk as issuer of the notes.

Examples of Hypothetical Payments

The following examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. The actual amount you receive and the resulting return will depend on the actual Starting Value, Threshold Value, Call Level, Observation Levels, Call Premiums, and the term of your investment. The following examples do not take into account any tax consequences from investing in the notes. These examples are based on:

1) a Starting Value of 100.00;

2) a Threshold Value of 100.00;

3) a Call Level of 100.00;

4) an expected term of the notes of approximately three years if the notes are not called on the first or second Observation Dates;

5) a Call Premium of 20.00% of the principal amount if the notes are called on the first Observation Date, 40.00% if called on the second Observation Date, and 60.00% if called on the final Observation Date (the midpoint of the applicable Call Premium ranges); and

6) Observation Dates occurring approximately one, two, and three years after the pricing date.

The hypothetical Starting Value of 100.00 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value of the Market Measure. 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.

Notes Are Called on an Observation Date

The notes will be called at $10.00 plus the applicable Call Premium on one of the Observation Dates if the Observation Level is equal to or greater than the Call Level.

Example 1 – The Observation Level on the first Observation Date is 110.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $2.00 = $12.00 per unit. After the notes are called, they will no longer remain outstanding and there will not be any further payments on the notes.

Example 2 – The Observation Level on the first Observation Date is below the Call Level, but the Observation Level on the second Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $4.00 = $14.00 per unit. After the notes are called, they will no longer remain outstanding and there will not be any further payments on the notes.

Example 3 – The Observation Levels on the first and second Observation Dates are below the Call Level, but the Observation Level on the third and final Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $6.00 = $16.00 per unit.

Notes Are Not Called on Any Observation Date

Example 4 – The notes are not called on any Observation Date and the Ending Value is less than the Threshold Value. The Redemption Amount will be less, and possibly significantly less, than the principal amount. For example, if the Ending Value is 85.00, the Redemption Amount per unit will be:

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 STR-1 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 called, your investment will 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.

§ Your investment return is limited to the return represented by the applicable Call Premium and 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-14. 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-14.

§ 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-14. 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.

§ Your return on the notes and the value of the notes may be affected by exchange rate movements and factors affecting the international securities markets.

§ 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 have not verified 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.

§ 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, 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.

§ 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 Considerations” beginning on page PS-28 of product supplement EQUITY INDICES STR-1.

Additional Risk Factors

All of the securities included in the Index are concentrated in one industry.

All of the securities included in the Index are issued by companies in the gold and silver mining industry. As a result, the securities that will determine the performance of the notes are concentrated in one industry. Although an investment in the notes will not give holders any ownership or other direct interests in the securities included in the Index, the return on an investment in the notes will be subject to certain risks similar to those associated with direct equity investments in the gold and silver mining industry. Accordingly, by investing in the notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

A limited number of Index components may affect its level and the Index is not necessarily representative of the gold and silver mining industry.

As of December 7, 2015, the top three Index components constituted 20.60% of the total weight of the Index and the top six Index components constituted 37.42% of the total weight of the Index. Any reduction in the market price of those securities is likely to have a substantial adverse impact on the level of the Index and the value of the notes.

While the securities included in the Index are common stocks, American Depositary Receipts (“ADRs”) or global depositary receipts (“GDRs”) of companies generally considered to be involved in various segments of the gold and silver mining industry, the securities included in the Index may not follow the price movements of the entire gold and silver mining industry generally. If the securities included in the Index decline in value, the Index will decline in value even if security prices in the gold and silver mining industry generally increase in value.

There is no direct correlation between the value of the notes or the level of the Index, on the one hand, and gold and silver prices, on the other hand.

Although the price of gold or silver is one factor that may influence the performance of the securities underlying the Index, the notes are not linked to the gold or silver spot prices or to gold or silver futures. There is no direct linkage between the level of the Index and the prices of gold and silver. While gold and silver prices may be one factor that could affect the prices of the securities included in the Index and, consequently, the level of the Index, the notes and the Redemption Amount are not directly linked to the movement of gold and silver prices and may be affected by factors unrelated to those movements. Investing in the notes is not the same as investing in gold or silver, and you should not invest in the notes if you wish to invest in a product that is linked directly to the price of gold or silver.

NYSE Arca, Inc. (“NYSE Arca”) the sponsor and compiler of the Index, retains significant control and discretionary decision-making over the Index and is responsible for decisions regarding the interpretation of and amendments to the Index rules, which may have an adverse effect on the level of the Index, the market value of the notes and the Redemption Amount on the maturity date.

NYSE Arca is the compiler of the Index and, as such, is responsible for the day-to-day management of the Index and for decisions regarding the interpretation of the rules governing the Index. NYSE Arca has the discretion to make operational adjustments to the Index and to the Index components, including discretion to exclude companies that otherwise meet the minimum criteria for inclusion in the Index. In addition, NYSE Arca retains the power to supplement, amend in whole or in part, revise or withdraw the Index rules at any time, any of which may lead to changes in the way the Index is compiled or calculated or adversely affect the Index in another way. Any of these adjustments to the Index or the Index rules may adversely affect the level of the Index, the market value of the notes and the Redemption Amount on the maturity date. The Index sponsor has no obligation to take the needs of any buyer, seller or holder of the notes into consideration at any time.

The performance of the securities underlying the Index may be influenced by gold and silver prices.

To the extent the price of gold or silver has a limited effect, if any, on the prices of the securities included in the Index, gold prices and silver prices are subject to volatile price movements over short periods of time, represent trading in commodities markets, which are substantially different from equities markets, and are affected by numerous factors. These include economic factors, including the structure of and confidence in the global monetary system, expectations of the future rate of inflation, the relative strength of, and confidence in, the U.S. dollar (the currency in which the prices of gold and silver are generally quoted), interest rates and gold and silver borrowing and lending rates, and global or regional economic, financial, political, regulatory, judicial, or other events.

Gold prices and silver prices may also be affected by industry factors such as industrial and jewelry demand, lending, sales and purchases of gold and silver by the official sector, including central banks and other governmental agencies and multilateral institutions which hold gold and silver, levels of gold and silver production and production costs, and short-term changes in supply and demand because of trading activities in the gold and silver markets. It is not possible to predict the aggregate effects of all or any combination of these factors.

We are not incorporating by reference these websites or any material included on those websites in this term sheet. The information reflects the policies of, and is subject to change by, NYSE Arca, the sponsor of the Index. NYSE Arca, which owns 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 NYSE Arca discontinuing publication of the Index are discussed in the section entitled “Description of the Notes—Discontinuance of an Index” beginning on page PS-21 of product supplement EQUITY INDICES STR-1. 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 a modified market capitalization weighted index comprised of securities issued by publicly traded companies involved primarily in the mining of gold or silver. The Index was initially launched and published in October 2004.

Eligibility Criteria for Index Components

The Index includes common stocks, American depositary receipts (“ADRs”) or global depositary receipts (“GDRs”) of selected companies that are involved in mining for gold and silver and that are listed for trading and electronically quoted on a major stock market that is accessible by foreign investors. Generally, this includes exchanges in most developed markets and major emerging markets, and includes companies that are cross-listed, i.e., both U.S. and Canadian listings. NYSE Arca will use its discretion to avoid exchanges and markets that are considered “frontier” in nature or have major restrictions to foreign ownership. The Index includes companies that derive at least 50% of their revenues from gold mining and related activities (40% for companies that are already included in the Index). Also, the Index will maintain an exposure to companies with a significant revenue exposure to silver mining in addition to gold mining, which will not exceed 20% of the Index weight at each rebalance.

Currently, only companies with a market capitalization of greater than $750 million that have an average daily trading volume of at least 50,000 shares and an average daily value traded of at least $1 million over the past three months are eligible for inclusion in the Index. Starting in December 2013, for companies already included in the Index, the market capitalization requirement at each rebalance will be $450 million, the average daily volume requirement will be at least 30,000 shares over the past three months and the average daily value traded requirement will be at least $600,000 over the past three months. Only one listing is permitted per company, and the listing representing the company’s ordinary shares is generally used.

NYSE Arca has the discretion to exclude a company even if the minimum criteria for inclusion has been met, or to include a company that fails to meet these criteria, if it feels that by doing so it maintains the quality and/or character of the Index.

Calculation of the Index

The Index is calculated by NYSE Arca on a price return basis. The calculation is based on the current modified market capitalization divided by a divisor. The divisor was determined on the initial capitalization base of the Index and the base level and may be adjusted as a result of corporate actions and composition changes, as described below. The level of the Index was set at 500.00 on December 20, 2002 which is the index base date. The Index is calculated using the following formula:

Where:

t = day of calculation;

N = number of constituent equities in the Index;

Qi,t = number of shares of equity i on day t;

Mi,t = multiplier of equity i;

Ci,t = price of equity i on day t; and

DIV = current index divisor on day t.

Index Maintenance

The Index is reviewed quarterly to ensure that at least 90% of the Index weight is accounted for by Index components that continue to meet the initial eligibility requirements. NYSE Arca may at any time and from time to time change the number of securities comprising the group by adding or deleting one or more securities, or replacing one or more securities contained in the group with one or more substitute securities of its choice, if in NYSE Arca’s discretion such addition, deletion or substitution is necessary or appropriate to maintain the quality and/or character of the Index. Components will be removed from the Index during the quarterly review if either (1) the market capitalization falls below $450 million or (2) the traded average daily shares for the previous three months is less than 30,000 shares and the average daily traded value for the previous three months is less than $600,000.

At the time of the quarterly rebalance, the component security weights (also referred to as the multiplier or share quantities of each component security) will be modified to conform to the following asset diversification requirements:

(1) the weight of any single component security may not account for more than 20% of the total value of the Index;

(2) the component securities are split into two subgroups–large and small, which are ranked by market capitalization weight in the Index. Large securities are defined as having a starting Index weight greater than or equal to 5%. Small securities are defined as having a starting Index weight below 5%; and

(3) the final aggregate weight of those component securities which individually represent more than 4.5% of the total value of the Index may not account for more than 45% of the total Index value.

The weights of the components securities (taking into account expected component changes and share adjustments) are modified in accordance with the Index’s diversification rules.

Diversification Rule 1: If any component stock exceeds 20% of the total value of the Index, then all stocks greater than 20% of the Index are reduced to represent 20% of the value of the Index. The aggregate amount by which all component stocks are reduced is redistributed proportionately across the remaining stocks that represent less than 20% of the Index value. After this redistribution, if any other stock then exceeds 20%, the stock is set to 20% of the Index value and the redistribution is repeated.

Diversification Rule 2: The components are sorted into two groups, large are components with a starting index weight of 5% or greater and small are components with a weight of under 5% (after any adjustments for Diversification Rule 1). The large group will represent in the aggregate 45% and the small group will represent 55% in the aggregate of the final index weight. This will be adjusted through the following process: The weight of each of the large stocks will be scaled down proportionately (with a floor of 5%) so that the aggregate weight of the large components will be reduced to represent 45% of the Index. If any large component stock falls below a weight equal to the product of 5% and the proportion by which the stocks were scaled down following this distribution, then the weight of the stock is set equal to 5% and the components with weights greater than 5% will be reduced proportionately. The weight of each of the small components will be scaled up proportionately from the redistribution of the large components. If any small component stock exceeds a weight equal to the product of 4.5% and the proportion by which the stocks were scaled down following this distribution, then the weight of the stock is set equal to 4.5%. The redistribution of weight to the remaining stocks is repeated until the entire amount has been redistributed.

Changes to the Index composition and/or the component security weights in the Index are determined and announced prior to taking effect. These changes typically become effective after the close of trading on the third Friday of each calendar quarter month in connection with the quarterly Index rebalance. The share quantities of each component security in the Index portfolio remains fixed between quarterly reviews except in the event of certain types of corporate actions such as stock splits, reverse stock splits, stock dividends, or similar events. The share quantities used in the Index calculation are not typically adjusted for shares issued or repurchased between quarterly reviews. However, in the event of a merger between two components, the share quantities of the surviving entity may be adjusted to account for any stock issued in the acquisition. NYSE Arca may substitute securities or change the number of securities included in the Index, based on changing conditions in the industry or in the event of certain types of corporate actions, including mergers, acquisitions, spin-offs, and reorganizations.

Corporate Action Related Adjustments

The Index may be adjusted in order to ensure that it continues to reflect as closely as possible the value of the underlying portfolio.

(1) Removal of constituents. Generally, any stock deleted from the Index as a result of a corporate action such as a merger, acquisition, spin-off, delisting or bankruptcy is not replaced by any new stock. If a company is removed from the Index, the divisor will be adapted to maintain the Index level.

(a) Mergers and Acquisitions. In the event that a merger or acquisition occurs between members of the Index, the acquired company is deleted and its market capitalization moves to the acquiring company’s stock. In the event that only one of the parties to a merger or acquisition is a member of the Index, an acquiring member of the Index continues as a member of the Index and its shares will be adjusted at the next rebalance while an acquired member of the Index is removed from the Index and the acquiring company may be considered for inclusion at the next rebalance.

(b) Suspensions and company distress. Immediately upon a company filing for bankruptcy, an announcement will be made to remove the stock from the Index effective for the sixth day following the bankruptcy. If the stock does not trade on the relevant exchange between the bankruptcy announcement and the next rebalance effective date, the stock may be deleted from the Index in that rebalance with a presumed market value of $0.

(c) Split-up / spin-off. The closing price of the Index constituent is adjusted by the value of the spin-off. Spun-off companies will not be automatically added to the Index at the time of the event.

(2) Dividends. The Index will be adjusted for special dividends. Special dividends include: (a) the declaration of a dividend additional to those dividends declared as part of a company’s normal results and dividend reporting cycle; or (b) the identification of an element of a dividend paid in line with a company’s normal results and dividend reporting cycle as an element that is unambiguously additional to the company’s normal payment.

(3) Rights issues and other rights. In the event of a rights issue, the price is adjusted for the value of the right on the ex-date, and the shares are increased according to the terms of the offering. The amount of the price adjustment is determined from the terms of the rights issue, including the subscription price, and the price of the underlying security. NYSE Arca will only effect adjustments if the rights represent a positive value, or are in-the-money, or alternatively, represent or can be converted into a tangible cash value.

(4) Bonus issues, stock splits and reverse stock splits. The number of shares included in the Index will be adjusted in accordance with the ratio given in the corporate action. The divisor will not change.

(5) Changes in number of shares. Changes in the number of shares outstanding, typically due to share repurchases, tenders, or offerings, will not be reflected in the Index until the next review unless the change is related to a specific corporate action.

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.

An investor’s household, as referenced on the cover of this term sheet, will generally include accounts held by any of the following, as determined by MLPF&S in its discretion and acting in good faith based upon information then available to MLPF&S:

· the investor’s spouse (including a domestic partner), siblings, parents, grandparents, spouse’s parents, children and grandchildren, but excluding accounts held by aunts, uncles, cousins, nieces, nephews or any other family relationship not directly above or below the individual investor;

· a family investment vehicle, including foundations, limited partnerships and personal holding companies, but only if the beneficial owners of the vehicle consist solely of the investor or members of the investor’s household as described above;

· a trust where the grantors and/or beneficiaries of the trust consist solely of the investor or members of the investor’s household as described above; provided that, purchases of the notes by a trust generally cannot be aggregated together with any purchases made by a trustee’s personal account.

Purchases in retirement accounts will not be considered part of the same household as an individual investor’s personal or other non-retirement account, except for individual retirement accounts (“IRAs”), simplified employee pension plans (“SEPs”), savings incentive match plan for employees (“SIMPLEs”), and single-participant or owners only accounts (i.e., retirement accounts held by self-employed individuals, business owners or partners with no employees other than their spouses).

Please contact your Merrill Lynch financial advisor if you have any questions about the application of these provisions to your specific circumstances or think you are eligible.

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 Considerations” beginning on page PS-28 of product supplement EQUITY INDICES STR-1, which you should carefully review prior to investing in the notes.

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.

However, even if the agreed-upon tax characterization of the notes were upheld, it is possible that the IRS could assert that a reconstitution or rebalancing (together, a “Rebalancing”) of the Market Measure is a significant modification of the notes due to an exercise of discretion with respect to the Rebalancing and, therefore, a taxable event to you. If the IRS were to prevail in treating any Rebalancing of the Market Measure as a taxable event, you would recognize capital gain or, possibly, loss on the notes on the date of such Rebalancing to the extent of the difference between the fair market value of the notes and your adjusted basis in the notes at that time. Such gain or loss generally would be short-term capital gain or loss.

Notes Held Through Foreign Entities

Pursuant to regulations and IRS Notice 2015-66, and subject to the exceptions described in “Material U.S. Federal Income Tax Considerations—Notes Held Through Foreign Entities” in the accompanying product supplement, FATCA’s withholding regime generally will apply to (i) withholdable payments (other than certain gross proceeds and 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, 2018, and (iii) foreign passthru payments made after the later of December 31, 2018, or the date that final regulations defining the term “foreign passthru payment” are published.

Non-U.S. Holders Generally

The following replaces the discussion of Substitute Dividend and Dividend Equivalent Payments in the accompanying product supplement under “Certain U.S. Federal Income Tax Considerations—Tax Treatment of Non-U.S. Holders.”

The Treasury Department has issued regulations under Code section 871(m) which impose U.S. federal withholding tax on “dividend equivalent” payments made on certain financial instruments linked to U.S. corporations (which the regulations refer to as “specified ELIs” or “specified NPCs,” as applicable) that are owned by non-U.S. holders. However, the regulations do not apply to “specified ELIs” or “specified NPCs” issued prior to January 1, 2017; accordingly, non-U.S. Holders of the notes will not be subject to tax under Code section 871(m).
