Market-Linked Step Up Notes
Linked to an International Equity Index Basket, due June  , 2021

Summary

The Market-Linked Step Up Notes Linked to an International Equity Index Basket, due June , 2021 (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 provide you with a Step Up Payment if the Ending Value of the international equity index basket described below (the “Basket”) 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 value of the Basket 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. Any payments on the notes, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Basket, subject to our credit risk. See “Terms of the Notes” below.

The Basket will be comprised of the EURO STOXX 50^® Index, the FTSE^® 100 Index, the Nikkei Stock Average Index, the Swiss Market Index^®, the S&P/ASX 200 Index, and the Hang Seng^® Index (each a “Basket Component”). On the pricing date, the EURO STOXX 50^® Index will be given an initial weight of 40.00%, each of the FTSE^® 100 Index and the Nikkei Stock Average Index will be given an initial weight of 20.00%, each of the Swiss Market Index^® and the S&P/ASX 200 Index will be given an initial weight of 7.50%, and the Hang Seng^® Index will be given an initial weight of 5.00%.

The economic terms of the notes (including the Step Up Payment) 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 BofAS 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 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-28.

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-1 identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

§ Depending on the performance of the Basket 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.

§ Your investment return may be less than a comparable investment directly in the stocks included in the Basket Components.

§ 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-30. 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-30.

§ 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-30. 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 value of the Basket, 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, nor BofAS, 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 BofAS, or any of our affiliates would be willing to purchase your notes in any secondary market (if any exists) at any time. BofAS 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 BofAS’s trading commissions and mark-ups. If you sell your notes to a dealer other than BofAS in a secondary market transaction, the dealer may impose its own discount or commission. BofAS has also advised us that, at its discretion and for your benefit, assuming no changes in market conditions from the pricing date, MLPF&S, or BofAS, 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 BofAS and our respective affiliates (including trading in shares of companies included in the Basket Components), and any hedging and trading activities we, BofAS 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.

§ Changes in the level of one of the Basket Components may be offset by changes in the levels of the other Basket Components. Due to the different Initial Component Weights, changes in the levels of some Basket Components will have a more substantial impact on the value of the Basket than similar changes in the levels of the other Basket Components.

§ The index sponsors may adjust their respective Basket Components in a way that affects their levels, and have no obligation to consider your interests.

§ You will have no rights of a holder of the securities included in the Basket Components, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

§ While we, BofAS or our respective affiliates may from time to time own securities of companies included in the Basket Components, except to the extent that our common stock is included in the Swiss Market Index®, we, BofAS and our

Market-Linked Step Up Notes TS-7

Market-Linked Step Up Notes
Linked to an International Equity Index Basket, due June  , 2021

respective affiliates do not control any company included in any Basket Component, and we have not verified any disclosure made by any other company.

§ Your return on the notes may be affected by factors affecting the international securities markets, specifically changes in the countries represented by the Basket Components. In addition, you will not obtain the benefit of any increase in the value of the currencies in which the securities in the Basket Components trade against the U.S. dollar which you would have received if you had owned the securities in the Basket Components during the term of your notes, although the value of the Basket may be adversely affected by general exchange rate movements in the market.

§ There may be potential conflicts of interest involving the calculation agents, one of which is our affiliate and one of which is BofAS. We have the right to appoint and remove the calculation agents.

§ 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 tax consequences of an investment in the notes are unclear. There is no direct legal authority regarding the proper U.S. federal tax treatment of the notes, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the notes are uncertain, and the IRS or a court might not agree with the treatment of the notes as prepaid financial contracts that are treated as “open transactions.” If the IRS were successful in asserting an alternative treatment of the notes, the tax consequences of the ownership and disposition of the notes, including the timing and character of income recognized by U.S. investors and the withholding tax consequences to non-U.S. investors, might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the notes, possibly retroactively.

The Basket

 The Basket is designed to allow investors to participate in the percentage changes in the levels of the Basket Components from the Starting Value to the Ending Value of the Basket. The Basket Components are described in the section “The Basket Components” below. Each Basket Component will be assigned an initial weight on the pricing date, as set forth in the table below.

For more information on the calculation of the value of the Basket, please see the section entitled “Description of the Notes—Basket Market Measures” beginning on page PS-23 of product supplement EQUITY INDICES SUN-1.

If May 23, 2019 were the pricing date, for each Basket Component, the Initial Component Weight, the closing level, the hypothetical Component Ratio and the initial contribution to the Basket value would be as follows:

Basket Component	Bloomberg Symbol	Initial Component Weight	Closing Level(1)(2)	Hypothetical Component Ratio(1)(3)	Initial Basket Value Contribution
EURO STOXX 50® Index	SX5E	40.00%	3,327.20	0.01202212	40.00
FTSE® 100 Index	UKX	20.00%	7,231.04	0.00276585	20.00

Hang Seng® Index	HSI	5.00%	27,267.13	0.00018337	5.00
				Starting Value	100.00

(1) The actual closing level of each Basket Component and the resulting actual Component Ratios will be determined on the pricing date, subject to adjustment as more fully described in the section entitled “Description of the Notes — Basket Market Measures — Determination of the Component Ratio for Each Basket Component” beginning on page PS-23 of product supplement EQUITY INDICES SUN-1 if a Market Disruption Event occurs on the pricing date as to any Basket Component.

(2) These were the closing levels of the Basket Components on May 23, 2019.

(3) Each hypothetical Component Ratio equals the Initial Component Weight of the relevant Basket Component (as a percentage) multiplied by 100, and then divided by the closing level of that Basket Component on May 23, 2019 and rounded to eight decimal places.

The calculation agents will calculate the value of the Basket on the calculation day by summing the products of the closing level for each Basket Component on such day and the Component Ratio applicable to such Basket Component. If a Market Disruption Event occurs as to any Basket Component on the scheduled calculation day, the closing level of that Basket Component will be determined as more fully described in the section entitled “Description of the Notes — Basket Market Measures — Observation Level or Ending Value of the Basket” on page PS-25 of product supplement EQUITY INDICES SUN-1.

The SX5E was created by STOXX Limited, a company owned by Deutsche Börse AG. Publication of the SX5E began on February 26, 1998, based on an initial index level of 1,000 at December 31, 1991. The SX5E is published in The Wall Street Journal and disseminated on the STOXX Limited website, which sets forth, among other things, the country and industrial sector weightings of the securities included in the SX5E, and updates these weightings at the end of each quarter. The SX5E is reported by Bloomberg under the ticker symbol “SX5E.”

On March 1, 2010, STOXX Limited announced the removal of the “Dow Jones” prefix from all of its indices, including the SX5E.

Methodology of the SX5E

The composition of the SX5E is reviewed annually in September, based on the closing stock data on the last trading day in August. The component stocks are announced on the first trading day in September. Changes in the composition of the SX5E are made to ensure that the SX5E includes 50 market sector leaders from within the SX5E. Changes to the component stocks are implemented on the third Friday in September and are effective the following trading day.

The composition of the SX5E is also reviewed monthly to ensure that component stocks still remain eligible for inclusion. The announcement will be on the first trading day of the month after close of the relevant markets. Any resulting changes from the monthly review are implemented on the close of the fifth trading day following the monthly review and are effective the next trading day. All stocks on the latest selection lists and initial public offering (IPO) stocks are reviewed for a fast-track addition on a quarterly basis. The announcement will be on the first trading day of the month after market close. The implementation is effected together with that of the STOXX Total Market Indices. A current list of the issuers that comprise the SX5E is available on the STOXX Limited website. Information contained in the STOXX Limited website is not incorporated by reference in, and should not be considered a part of, this term sheet.

The free float factors for each component stock used to calculate the SX5E, as described below, are reviewed, calculated and implemented on a quarterly basis and are fixed until the next quarterly review. Each component’s weight is capped at 10% of the SX5E’s total free float market capitalization.

The SX5E is also reviewed on an ongoing basis. Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings and bankruptcy) that affect the SX5E composition are immediately reviewed. Any changes are announced, implemented and effective in line with the type of corporate action and the magnitude of the effect.

Computation of the SX5E

The SX5E is calculated with the “Laspeyres formula,” which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the index value can be expressed as follows:

The “free float market capitalization of the index” is equal to the sum of the product of the price, number of shares outstanding and free float factor for each component stock as of the time the SX5E is being calculated. The free float factor reduces the number of shares outstanding to the actual amount available on the market. All fractions of the total number of shares that are larger than 5.00% and whose holding is of a long-term nature are excluded from the index calculation. The free float factor typically excludes cross-ownership (stock owned either by the company itself or other companies), government ownership, private ownership, and restricted shares that cannot be traded during a certain period or have a foreign ownership restriction. Block ownership is not applied for holdings of custodian nominees, trustee companies, mutual funds, investment companies with short-term investment strategies, pension funds and similar entities.

The SX5E is also subject to a divisor, which is adjusted to maintain the continuity of SX5E values despite changes due to corporate actions. All corporate actions and dividends are implemented at the effective date (ex-date); i.e., with corporate actions where cash or other corporate assets are distributed to shareholders, the price of the stock will decrease on the ex-date. The following is a summary of the adjustments to any component stock made for corporate actions and the effect of such adjustment on the divisor, where

shareholders of the component stock will receive “B” number of shares for every “A” share held (where applicable). If the new shares have a dividend disadvantage —i.e., the new shares have a different dividend from that paid on the old shares — the price for these new shares will be adjusted according to the gross dividend amount. The divisor may increase, decrease or be held constant.

DIVISOR:	Decrease	A) Cash dividend (applies to return indices only) adjusted price (net return) = closing price − announced dividend * (1 − withholding tax) adjusted price (gross return) = closing price − announced dividend

DIVISOR:	Constant	E) Stock Dividend adjusted price = closing price * A / (A + B) new number of shares = old number of shares * (A + B) / A
	Decrease	F) Stock Dividend (from treasury stock) If treated as regular cash dividend, only the return indices are adjusted. adjusted price = closing price – closing price * B / (A + B) If treated as extraordinary dividend, the price and the return indices are adjusted. adjusted price = closing price – closing price * B / (A + B)
DIVISOR:	Decrease	G) Stock Dividend of a Different Company Security adjusted price = (closing price * A − price of the different company security * B) / A
DIVISOR:	Decrease	H) Return of Capital and Share Consolidation adjusted price = (closing price − capital return announced by company * (1 − withholding tax)) * A / B new number of shares = old number of shares * B / A
DIVISOR:	Decrease	I) Repurchase Shares-Self-Tender adjusted price = ((price before tender * old number of shares) − (tender price * number of tendered shares))

The FTSE^® 100 Index

The FTSE^® 100 Index (the “UKX”) is a market-capitalization weighted index calculated, published and disseminated by FTSE, an independent company wholly owned by the London Stock Exchange Group (the “LSE”). The UKX is designed to measure the composite performance of the 100 largest UK domiciled blue chip companies that pass screening for size and liquidity traded on the LSE. The UKX was launched on January 3, 1984 and has a base date of December 30, 1983. The UKX is reported by Bloomberg under the ticker symbol “UKX.”

The UKX is calculated by (i) multiplying the per share price of each stock included in the UKX by the number of outstanding shares and by the free float factor applicable to such stock, (ii) calculating the sum of all these products (such sum referred to hereinafter as the “FTSE Aggregate Market Value”) as of the starting date of the UKX and (iii) dividing the FTSE Aggregate Market Value by a divisor which represents the total issued share capital of the UKX on the base date and which can be adjusted to allow changes in the issued share capital of individual underlying stocks (including the deletion and addition of stocks, the substitution of stocks, stock dividends and stock splits) to be made without distorting the UKX. Because of such capitalization weighting, movements in share prices of companies with relatively larger market capitalization will have a greater effect on the level of the entire index than will movements in share prices of companies with relatively smaller market capitalization.

The 100 stocks included in the UKX (the “FTSE 100 Index Underlying Stocks”) were selected from a reference group of stocks trading on the LSE which were selected by excluding certain stocks that have low liquidity based on public float, accuracy and reliability of prices, size and number of trading days. The FTSE 100 Index Underlying Stocks were selected from this reference group by selecting 100 stocks with the largest market value. A list of the issuers of the FTSE 100 Index Underlying Stocks is available from FTSE. The UKX is reviewed quarterly by the FTSE Russell Europe, Middle East & Africa Regional Equity Advisory Committee (the “Committee”) in order to maintain continuity in the level. The FTSE 100 Index Underlying Stocks may be replaced, if necessary, in accordance with deletion/addition rules which provide generally for the removal and replacement of a stock from the UKX if such stock is delisted or its issuer is subject to a takeover offer that has been declared unconditional or it has ceased to be a viable component of the UKX. To maintain continuity, a stock will be added at the quarterly review if it has risen to 90th place or above and a stock will be deleted if at the quarterly review it has fallen to 111th place or below, in each case ranked on the basis of market value.

The following graph shows the daily historical performance of the UKX in the period from January 1, 2008 through May 23, 2019. We obtained this historical data from Bloomberg L.P. We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On May 23, 2019, the closing level of the UKX was 7,231.04.

The Nikkei Stock Average Index

The Nikkei Stock Average (the “NKY”) is a stock index calculated, published and disseminated by Nikkei Inc., the index sponsor of the NKY, which measures the composite price performance of certain Japanese stocks. The NKY currently is based on 225 underlying stocks trading on the Tokyo Stock Exchange (the “TSE”) representing a broad cross-section of Japanese industries. ETFs, REITs, preferred stocks, preferred securities and tracking stocks are excluded. All 225 components of the NKY are listed in the First Section of the TSE. Stocks listed in the First Section of the TSE are among the most actively traded stocks on the TSE. The index rules require that the 75 most liquid issues (one-third of the components of the NKY) be included in the NKY.

Standards for Listing and Maintenance

The NKY is reviewed annually at the beginning of October. Stocks with high market liquidity are added and those with low liquidity are deleted. At the same time, to take into account changes in industry structure, the index sponsor examines the balance of the sectors, in terms of the number of constituents. Liquidity of a stock is assessed by the two measures: “trading value” and “magnitude of price fluctuation by volume,” which is calculated as (High price/Low price) / Volume. Among stocks on the TSE First Section, the top 450 stocks in terms of liquidity are selected to form the “high liquidity group”. Those constituents not in the high liquidity group are deleted. Those non-constituent stocks which are in the top 75 of the high liquidity group are added. After the liquidity deletions and additions, constituents are deleted and added to balance the number of constituents among sectors, and to make the total number of the constituents equal 225.

The 225 companies included in the NKY are divided into six sector categories: Technology, Financials, Consumer Goods, Materials, Capital Goods/Others and Transportation and Utilities. The six sector categories are divided into 36 industrial classifications as follows:

· Technology—Pharmaceuticals, Electrical Machinery, Automobiles and Auto parts, Precision Machinery, Telecommunications;

· Financials—Banks, Miscellaneous Financial Services, Securities, Insurance;

· Consumer Goods—Marine Products, Food, Retail, Services;

· Materials—Mining, Textiles, Paper and Pulp, Chemicals, Oil, Rubber, Ceramics, Steel, Nonferrous Metals, Trading Companies;

· Capital Goods/Others—Construction, Machinery, Shipbuilding, Transportation Equipment, Miscellaneous Manufacturing, Real Estate; and

· Transportation and Utilities—Railroads and Buses, Trucking, Shipping, Airlines, Warehousing, Electric Power, Gas.

Among the 450 “high liquidity” stocks, half of those that belong to any sector are designated as the “appropriate number of stocks” for that sector. The actual number of constituents in a sector is then compared with its “appropriate number,” and if the actual number is larger or smaller than the “appropriate number,” then components are deleted or added, as necessary. Stocks to be deleted are selected from stocks with lower liquidity and stocks to be added are selected from stocks with higher liquidity. Stocks selected according to the foregoing procedures are candidates for addition or deletion, as applicable, and the final determinations will be made by the index sponsor.

The NKY is also reviewed on an ongoing basis in response to extraordinary developments, such as bankruptcies or mergers. Any stock removed from the TSE First Section due to any of the following reasons will be removed from the NKY: (i) bankruptcy, including filing for Corporate Reorganization Act, Civil Rehabilitation Act, or liquidation; (ii) corporate restructuring such as merger, share exchange or share transfer; (iii) excess debt or other reasons; or (iv) transfer to the TSE Second Section. In addition, component stocks designated as “securities under supervision” become deletion candidates. However, the decision to delete such candidates will be made by examining the sustainability and the probability of delisting for each individual case. Upon deletion of a stock from the NKY, the index sponsor will generally select as a replacement the most liquid stock that is both in the “high liquidity group” and in the same sector as the deleted stock. When deletions are known in advance, replacements may be selected as part of the periodic review process or by using similar procedures.

Calculation of the NKY

The NKY is a modified price-weighted index (i.e., a stock’s weight in the NKY is based on its price per share rather than the total market capitalization of the issuer) where the sum of the constituent stock prices, adjusted by the presumed par value, is divided by a divisor.

The NKY is calculated by (i) converting the component stocks that do not have a par value of 50 yen to 50 yen par value, as described below, (ii) calculating the sum of the adjusted share prices of each component stock and (iii) dividing such sum by a divisor. Most listed companies in Japan have a par value of 50 yen. All companies included in the NKY are given an equal weighting based on a par value of 50 yen. Stocks with irregular par values are modified to reflect a 50 yen par value. For example, a stock with a 500 yen par value will have its share price divided by 10 to give a 50 yen par value price. The level of the NKY is calculated every 15 seconds during TSE trading hours.

Market-Linked Step Up Notes TS-17

In order to maintain continuity in the NKY in the event of certain changes due to non-market factors affecting the component stocks, such as the addition or deletion of stocks, substitution of stocks, stock splits or distributions of assets to stockholders, the divisor used in calculating the NKY is adjusted in a manner designed to prevent any instantaneous change or discontinuity in the level of the NKY. Thereafter, the divisor remains at the new value until a further adjustment is necessary as the result of another change. As a result of such change affecting any component stock, the divisor is adjusted in such a way that the sum of all share prices immediately after such change multiplied by the applicable weight factor and divided by the new divisor (i.e., the level of the NKY immediately after such change) will equal the level of the NKY immediately prior to the change. For the NKY, presumed par value may be changed for large scale splits and reverse splits. The divisor is not changed in these cases.

The following graph shows the daily historical performance of the NKY in the period from January 1, 2008 through May 23, 2019. We obtained this historical data from Bloomberg L.P. We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On May 23, 2019, the closing level of the NKY was 21,151.14.

The Swiss Market Index^®

The Swiss Market Index^® (Bloomberg ticker “SMI”) (the “SMI”):

· was first launched with a base level of 1,500 as of June 30, 1988; and

· is sponsored, calculated, published and disseminated by the SIX Swiss Exchange.

The SMI is a price return float-adjusted market capitalization-weighted index of the 20 largest stocks traded on the SIX Swiss Exchange. The Management Committee of SIX Swiss Exchange is supported by an Index Commission (advisory board) in all index-related matters, notably in connection with changes to the index rules and adjustments, additions and exclusions outside of the established review and acceptance period. The Index Commission meets at least twice annually.

Index Composition and Selection Criteria

The SMI is comprised of the 20 highest ranked stocks traded on the SIX Swiss Exchange that have a free float of 20% or more and that are not investment companies. The equity universe is largely Swiss domestic companies; however, in some cases, foreign issuers with a primary listing on the SIX Swiss Exchange or investment companies that do not hold any shares of any other eligible company and that have a primary listing on the SIX Swiss Exchange may be included.

The ranking of each security is determined by a combination of the following criteria:

· average free-float market capitalization over the last 12 months (compared to the capitalization of the entire SIX Swiss Exchange index family), and

· cumulative on order book turnover over the last 12 months (compared to the total turnover of the SIX Swiss Exchange index family).

For companies that have been listed during the 12-month period, the cumulated on order book turnover will be extrapolated, whereby generally the first five trading days for those shares will not be included in the calculation.

The SMI is reconstituted annually after prior notice of at least two months on the third Friday in September after the close of trading.

The reconstitution is based on data from the previous July 1 through June 30. Provisional interim selection (ranking) lists are also published following the end of the third, fourth and first financial quarters.

In order to reduce turnover, an index constituent will not be replaced unless it is ranked below 23 or, if it is ranked 21 or 22, if another share ranks 18 or higher. If a company has primary listings on several exchanges and less than 50% of that company’s total turnover is generated on the SIX Swiss Exchange, it will not be included in the SMI unless it ranks at least 18 or better on the selection list on the basis of its turnover alone (i.e., without considering its free float).

Maintenance of the SMI

Constituent Changes. In the case of major market changes as a result of capital events such as mergers or new listings, the Management Committee of SIX Swiss Exchange can decide at the request of the Index Commission that a security should be admitted to the SMI outside the annual review period as long as it clearly fulfills the criteria for inclusion. For the same reasons, a security can also be excluded if the requirements for admission to the SMI are no longer fulfilled. As a general rule, extraordinary acceptances into the SMI take place after a three-month period on a quarterly basis after the close of trading on the third Friday of March, June, September and December (for example, a security listed on or before the fifth trading day prior to the end of November cannot be included until the following March). An announced insolvency is deemed to be an extraordinary event and the security will be removed from the SMI with five trading days’ prior notice if the circumstances permit such notice.

Number of Shares and Free Float. The securities included in the SMI are weighted according to their free float. This means that shares deemed to be in firm hands are subtracted from the total market capitalization of that company. The free float is calculated on the basis of outstanding shares. Issued and outstanding equity capital is, as a rule, the total amount of equity capital that has been fully subscribed and wholly or partially paid in and documented in the Commercial Register. Not counting as issued and outstanding equity capital are the approved capital and the conditional capital of a company. The free float is calculated on the basis of listed shares only. If a company offers several different categories of listed participation rights, each is treated separately for purposes of index calculation.

Shares held deemed to be in firm hands are shareholdings that have been acquired by one person or a group of persons in companies domiciled in Switzerland and which, upon exceeding 5%, have been reported to the SIX Swiss Exchange. Shares of persons and groups of persons who are subject to a shareholder agreement which is binding for more than 5% of the listed shares or who, according to publicly known facts, have a long-term interest in a company, are also deemed to be in firm hands.

For the calculation of the number of shares in firm hands, the SIX Swiss Exchange may also use other sources than the reports submitted to it. In particular, the SIX Swiss Exchange may use data gained from issuer surveys that it conducts itself.

In general, shares held by custodian nominees, trustee companies, investment funds, pension funds and investment companies are deemed free-floating regardless whether a report has been made to the SIX Swiss Exchange. The SIX Swiss Exchange classifies at its own discretion persons and groups of persons who, because of their area of activity or the absence of important information, cannot be clearly assigned.

The free-float rule applies only to bearer shares and registered shares. Capital issued in the form of participation certificates and bonus certificates is taken into full account in calculating the SMI because it does not confer voting rights.

Market-Linked Step Up Notes TS-19

Market-Linked Step Up Notes

The number of securities in the SMI and the free-float factors are adjusted after the close of trading on four adjustment dates per year, the third Friday of March, June, September and December. Such changes are pre-announced at least one month before the adjustment date, although the index sponsor reserves the right to take account of recent changes before the adjustment date in the actual adjustment, so the definite new securities are announced five trading days before the adjustment date.

In order to avoid frequent slight changes to the weighting and to maintain the stability of the SMI, any extraordinary change of the total number of outstanding securities or the free float will only result in an extraordinary adjustment if it exceeds 10% and 5% respectively, occurs from one trading day to the next one and is in conjunction with a corporate action.

After a takeover, SIX Swiss Exchange may, in exceptional cases, adjust the free float of a company upon publication of the end results after a five-day notification period or may exclude the security from the relevant index family. When an insolvency has been announced, an extraordinary adjustment will be made and the affected security will be removed from the SMI after five trading days’ notice.

The index sponsor reserves the right to make an extraordinary adjustment, in exceptional cases, without observing the notification period.

Calculation of the SMI

The index sponsor calculates the SMI using the “Laspeyres formula,” with a weighted arithmetic mean of a defined number of securities issues. The formula for calculating the index value can be expressed as follows:

Index  = Free Float Market Capitalization of the index
Divisor

The “free float market capitalization of the index” is equal to the sum of the product of the last-paid price, the number of shares, the free-float factor and, if a foreign stock is included, the current CHF exchange rate as of the time the index value is being calculated. The index value is calculated in real time and is updated whenever a trade is made in a component stock. Where any index component stock price is unavailable on any trading day, SIX Swiss Exchange will use the last reported price for such component stock. Only prices from the SIX Swiss Exchange’s electronic order book are used in calculating the SMI.

Divisor Value and Adjustments

The divisor is a technical number used to calculate the SMI and is adjusted to reflect changes in market capitalization due to corporate events, and is adjusted by SIX Swiss Exchange to reflect corporate events, as described in the index rules.

The S&P/ASX 200 Index

The S&P/ASX 200 Index (Bloomberg ticker “AS51”) (the “AS51”):

· was first launched in 1979 by the Australian Securities Exchange and was acquired and re-launched by its current index sponsor on April 3, 2000; and

· is sponsored, calculated, published and disseminated by S&P Dow Jones Indices LLC (“S&P”).

The AS51 includes 200 companies and covers approximately 80% of the Australian equity market by market capitalization. As discussed below, the AS51 is not limited solely to companies having their primary operations or headquarters in Australia or to companies having their primary listing on the Australian Securities Exchange (the “ASX”). All ordinary and preferred shares (if such preferred shares are not of a fixed income nature) listed on the ASX, including secondary listings, are eligible for the AS51. Hybrid stocks, bonds, warrants, preferred stock that provides a guaranteed fixed return and listed investment companies are not eligible for inclusion.

The AS51 is intended to provide exposure to the largest 200 eligible securities that are listed on the ASX by float-adjusted market capitalization. Constituent companies for the AS51 are chosen based on market capitalization, public float and liquidity. All index-eligible securities that have their primary or secondary listing on the ASX are included in the initial selection of stocks from which the 200 index stocks may be selected.

The float-adjusted market capitalization of companies is determined based on the daily average market capitalization over the last six months. The security’s price history over the last six months, the latest available shares on issue and the investable weight factor (the “IWF”), are the factors relevant to the calculation of daily average market capitalization. The IWF is a variable that is primarily used to determine the available float of a security for ASX listed securities.

Number of Shares

When considering the index eligibility of securities for inclusion or promotion into S&P/ASX indices, the number of index securities under consideration is based upon the latest available ASX quoted securities. For domestic securities (companies incorporated in Australia and traded on the ASX, companies incorporated overseas but exclusively listed on the ASX and companies incorporated overseas and traded on other markets but most of its trading activity is on the ASX), this figure is purely based upon the latest available data from the ASX.

Foreign-domiciled securities may quote the total number of securities on the ASX that is representative of their global equity capital; whereas other foreign-domiciled securities may quote securities on the ASX on a partial basis that represents their Australian equity capital. In order to overcome this inconsistency, S&P will quote the number of index securities that are represented by CHESS Depositary Interests (“CDIs”) for a foreign entity. When CDIs are not issued, S&P will use the total securities held on the Australian register (CHESS and, where supplied, the issuer sponsored register). This quoted number for a foreign entity is representative of the Australian equity capital, thereby allowing the AS51 to be increasingly reflective of the Australian market.

The number of CDIs or shares of a foreign entity quoted on the ASX can experience more volatility than is typically the case for ordinary shares on issue. Therefore, an average number on issue will be applied over a six-month period.

Where CDI information is not supplied to the ASX by the company or the company’s share register, estimates for Australian equity capital will be drawn from CHESS data and, ultimately, registry-sourced data.

IWF

The IWF represents the float-adjusted portion of a stock’s equity capital. Therefore any strategic holdings that are classified as either corporate, private or government holdings reduce the IWF which, in turn, results in a reduction in the float-adjusted market capital.

The IWF ranges between 0 and 1, is calculated as 1 – Sum of the % held by strategic shareholders who possess 5.00% or more of issued shares, and is an adjustment factor that accounts for the publicly available shares of a company. A company must have a minimum IWF of 0.3 to be eligible for index inclusion.

S&P Dow Jones Indices identifies the following shareholders whose holdings are considered to be control blocks and are subject to float adjustment:

1. Government and government agencies;

2. Controlling and strategic shareholders/partners;

3. Any other entities or individuals which hold more than 5%, excluding insurance companies, securities companies and investment funds; and

4. Other restricted portions such as treasury stocks.

Liquidity Test

Only stocks that are regularly traded are eligible for inclusion. Eligible stocks are considered for index inclusion based on their stock median liquidity (median daily value traded divided by its average float-adjusted market capitalization for the last six months relative to the market capitalization weighted average of the stock median liquidities of the 500 constituents of the All Ordinaries index, another member of the S&P/ASX index family).

Maintenance of the AS51

S&P rebalances constituents quarterly to ensure adequate market capitalization and liquidity using the previous six months’ data to determine index eligibility. Quarterly review changes take effect the third Friday of March, June, September and December. Eligible stocks are considered for index inclusion based on their float-adjusted market capitalization rank relative to the stated quota of 200 securities. For example, a stock that is currently in the S&P/ASX 300 and is ranked at 175, based on float-adjusted market capitalization, within the universe of eligible securities may be considered for inclusion into the AS51, provided that liquidity hurdles are met.

In order to limit the level of index turnover, eligible securities will only be considered for index inclusion once another stock is excluded due to a sufficiently low rank and/or liquidity, based on the float-adjusted market capitalization. Potential index inclusions and exclusions need to satisfy buffer requirements in terms of the rank of the stock relative to a given index. The buffers are established to limit the level of index turnover that may take place at each quarterly rebalancing.

Between rebalancing dates, an index addition is generally made only if a vacancy is created by an index deletion. Index additions are made according to float-adjusted market capitalization and liquidity. An initial public offering is added to the AS51 only when an appropriate vacancy occurs and is subject to proven liquidity for at least two months. An exception may be made for extraordinary large offerings where sizeable trading volumes justify index inclusion.

Deletions can occur between index rebalancing dates due to acquisitions, mergers and spin-offs or due to suspension or bankruptcies. The decision to remove a stock from the AS51 will be made once there is sufficient evidence that the transaction will be completed. Stocks that are removed due to mergers and acquisitions are removed from the AS51 at the cash offer price for cash-only offers. Otherwise, the best available price in the market is used.

Share numbers for all index constituents are updated quarterly and are rounded to the nearest thousand. The update to the number of issued shares will be considered if the change is at least 5% of the float adjusted shares or $100 million in value.

Share updates for foreign-domiciled securities will take place annually at the March rebalancing. The update to the number of index shares will only take place when the six-month average of CDIs or the Total Securities held in the Australian branch of issuer sponsored register (where supplied) and in CHESS, as of the March rebalancing, differs from the current index shares by either 5% or a market-cap dollar amount greater than A$ 100 million. Where CDI information is not supplied to the ASX by the company or the company’s share register, estimates for Australian equity capital will be drawn from CHESS data and, ultimately, registry-sourced data.

Intra-quarter share changes are implemented at the effective date or as soon as reliable information is available; however, they will only take place in the following circumstances:

§ changes in a company’s float-adjusted shares of 5% or more due to market-wide shares issuance;

§ rights issues, bonus issues and other major corporate actions; and

§ share issues resulting from index companies merging and major off-market buy-backs.

Share changes due to mergers or acquisitions are implemented when the transaction occurs, even if both of the companies are not in the same index and regardless of the size of the change.

IWFs are reviewed annually as part of the September quarterly review. However, any event that alters the float of a security in excess of 5% will be implemented as soon as practicable by an adjustment to the IWF.

The function of the IWF is also to manage the index weight of foreign-domiciled securities that quote shares on the basis of CDIs. Due to the volatility that is displayed by CDIs, unusually large changes in the number of CDIs on issue could result. Where this is the case, the IWF may be used to limit the effect of unusually large changes in the average number of CDIs (and, thereby, limit the potential to manipulate this figure). Where the Australian Index Committee sees fit to apply the IWF in this manner, the rationale for the decision will be announced to the market. This will be reviewed annually at the March-quarter index rebalancing date.

Calculation of the AS51

The AS51 is calculated using a base-weighted aggregate methodology. The value of the AS51 on any day for which an index value is published is determined by a fraction, the numerator of which is the aggregate of the price of each stock in the AS51 times the number of shares of such stock included in the AS51 times that stock’s IWF, and the denominator of which is the divisor, which is described more fully below.

In order to prevent the value of the AS51 from changing due to corporate actions, all corporate actions may require S&P to make an index or divisor adjustment, as described in S&P’s rules. This helps maintain the value of the AS51 and ensures that the movement of the AS51 does not reflect the corporate actions of the individual companies that comprise the AS51.

In situations where an exchange is forced to close early due to unforeseen events, such as computer or electric power failures, weather conditions or other events, S&P will calculate the closing price of the indices based on (1) the closing prices published by the exchange or (2) if no closing price is available, the last regular trade reported for each security before the exchange closed. If the exchange fails to open due to unforeseen circumstances, S&P treats this closure as a standard market holiday. The AS51 will use the prior day’s closing prices and shifts any corporate actions to the following business day. If all exchanges fail to open or in other extreme circumstances, S&P may determine not to publish the AS51 for that day.

S&P reserves the right to recalculate the AS51 under certain limited circumstances.

The Hang Seng^® Index

The Hang Seng^® Index (the “HSI”) is calculated, maintained and published by Hang Seng^® Indexes Company Limited (“HSIL”), a wholly owned subsidiary of Hang Seng Bank, in concert with the HSI Advisory Committee and was first developed, calculated and published on November 24, 1969. The HSI is a free float-adjusted market capitalization weighted stock market index that is designed to reflect the performance of the Hong Kong stock market.

Only companies with a primary listing on the main board of the Stock Exchange of Hong Kong (“SEHK”) are eligible as constituents of the HSI. Mainland China enterprises that have an H-share listing in Hong Kong will not be eligible for inclusion in the HSI unless the company has no unlisted share capital. In addition, to be eligible for selection, a company: (1) must be among those that constitute the top 90% of the total market value of all primary listed shares on the SEHK (the market value of a company refers to the average of its month-end market capitalizations for the past 12 months); (2) must be among those that constitute the top 90% of the total turnover of all primary listed shares on the SEHK in a sufficient number of measurement sub-periods (turnover is assessed over the last eight quarterly sub-periods: if a company was in the top 90% in any of the most recent four sub-periods, it receives two points; if it was in the top 90% in any of the latter four sub-periods, it receives one point. A company must attain a “score” of eight points to meet the turnover requirement); and (3) should normally have a listing history of 24 months (there are exceptions for companies that have shorter listing histories but large market values and/or high turnover scores). From the many eligible candidates, final selections are based on the following: (1) the market value and turnover rankings of the companies; (2) the representation of the sub-sectors within the HSI directly reflecting that of the market; and (3) the financial performance of the companies. The number of constituents is fixed at 50.

Calculation of the HSI

The calculation methodology of the HSI is a free float-adjusted market capitalization weighting with a cap on individual stocks. Under this calculation methodology, shares held by any entities (excluding custodians, trustees, mutual funds and investment companies) which control more than 5% of shares are excluded for index calculation:

· Strategic holdings (governments and affiliated entities or any other entities which hold substantial shares in the company would be considered as non-free-float unless otherwise proved);

· Directors’ and management holdings (directors, members of the board committee, principal officers or founding members);

· Corporate cross holdings (publicly traded companies or private firms / institutions); and

· Lock-up shares (shareholdings with a publicly disclosed lock-up arrangement).

A free float-adjusted factor representing the proportion of shares that is free floated as a percentage of the issued shares, is rounded up to the nearest multiple of 5% for the calculation of the HSI and is updated quarterly.

A cap of 15% on individual stock weightings was applied before September 2014. In September 2014, it was decided that the cap would be lowered to 10%. This change will be phased in over a 12-month period through five rounds of Index rebalancing. A cap factor is calculated quarterly to coincide with the regular update of the free float-adjusted factor. Additional re-capping is performed upon constituent changes.

The formula for the index calculation is as follows:

Current Index =

where:

P_t :    current price at day t;

P_t-1:  closing price at day t-1;

IS:    number of issued shares;

FAF: free-float-adjusted factor, which is between 0 and 1; and

CF:  capping factor, which is between 0 and 1.

Supplement to the Plan of Distribution

Under our distribution agreement with BofAS, BofAS 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.

BofAS has informed us of the information in the following paragraph. MLPF&S will purchase the notes from BofAS for resale, and will receive a selling concession in connection with the sale of the notes in an amount up to the full amount of underwriting discount set forth on the cover of this term sheet.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than two 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 two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the notes occurs more than two business days from the pricing date, purchasers who wish to trade the notes more than two 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 and/or one of its affiliates acting as a principal in effecting the transaction for your account.

MLPF&S and BofAS 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 and BofAS’s trading commissions and mark-ups or mark-downs. MLPF&S and BofAS may act as principal or agent in these market-making transactions; however, neither is obligated to engage in any such transactions. BofAS has informed us that at their discretion and for your benefit, assuming no changes in market conditions from the pricing date, MLPF&S and BofAS 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 BofAS or MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Basket and the remaining term of the notes. However, none of us, MLPF&S, BofAS, 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, BofAS, or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

BofAS has informed us that, as of the date of this term sheet, it expects that if you hold your notes in a BofAS account, the value of the notes shown on your account statement will be based on BofAS’s estimate of the value of the notes if BofAS 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 BofAS 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; and

· 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 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 Basket. 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, will be calculated based on the $10 Principal Amount per unit and will depend on the performance of the Basket. 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 BofAS or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including BofAS and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Basket Components, 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.

BofAS 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 BofAS 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 BofAS or any third party hedge providers.

United States Federal Tax Considerations

This discussion supplements and, to the extent inconsistent therewith, supersedes the discussion in the accompanying product supplement under “Material U.S. Federal Income Tax Considerations.”

There are no statutory, judicial or administrative authorities that address the U.S. federal income tax treatment of the notes or instruments that are similar to the notes. In the opinion of our counsel, Davis Polk & Wardwell LLP, a note should be treated as a prepaid financial contract that is an “open transaction” for U.S. federal income tax purposes. However, there is uncertainty regarding this treatment. Moreover, our counsel’s opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date.

Assuming this treatment of the notes is respected and subject to the discussion in “Material U.S. Federal Income Tax Considerations” in the accompanying product supplement, the following U.S. federal income tax consequences should result:

· You should not recognize taxable income over the term of the notes prior to maturity, other than pursuant to a sale or other disposition.

· Upon a sale or other disposition (including retirement) of a note, you should recognize capital gain or loss equal to the difference between the amount realized and your tax basis in the note. Such gain or loss should be long-term capital gain or loss if you held the note for more than one year.

We do not plan to request a ruling from the IRS regarding the treatment of the notes, and the IRS or a court might not agree with the treatment described herein. In particular, the IRS could treat the notes as contingent payment debt instruments, in which case the tax consequences of ownership and disposition of the notes, including the timing and character of income recognized, could be materially and adversely affected. Moreover, the U.S. Treasury Department and the IRS have requested comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar financial instruments and have indicated that such transactions may be the subject of future regulations or other guidance. In addition, members of Congress have proposed legislative changes to the tax treatment of derivative contracts. Any legislation, Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect. You should consult your tax advisor regarding possible alternative tax treatments of the notes and potential changes in applicable law.

Non-U.S. Holders. Subject to the discussions in the next paragraph and in “Material U.S. Federal Income Tax Considerations” in the accompanying product supplement, if you are a Non-U.S. Holder (as defined in the accompanying product supplement) of the notes, you generally should not be subject to U.S. federal withholding or income tax in respect of any amount paid to you with respect to the notes, provided that (i) income in respect of the notes is not effectively connected with your conduct of a trade or business in the United States, and (ii) you comply with the applicable certification requirements.

As discussed under “Material U.S. Federal Income Tax Considerations—Non-U.S. Holders Generally—Substitute Dividend and Dividend Equivalent Payments” in the accompanying product supplement, Section 871(m) of the Internal Revenue Code generally imposes a 30% withholding tax on “dividend equivalents” paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. Treasury regulations under Section 871(m), as modified by an IRS notice, exclude from their scope financial instruments issued prior to January 1, 2021 that do not have a “delta” of one with respect to any U.S. equity. Based on the terms of the notes and representations provided by us as of the date of this preliminary pricing supplement, our counsel is of the opinion that the notes should not be treated as transactions that have a “delta” of one within the meaning of the regulations with respect to any U.S. equity and, therefore, should not be subject to withholding tax under Section 871(m). However, the final determination regarding the treatment of the notes under Section 871(m) will be made as of the pricing date for the notes and it is possible that the notes will be subject to withholding tax under Section 871(m) based on circumstances on that date.

A determination that the notes are not subject to Section 871(m) is not binding on the IRS, and the IRS may disagree with this determination. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to a U.S. equity to which the notes relate. You should consult your tax advisor regarding the potential application of Section 871(m) to the notes.

If withholding tax applies to the notes, we will not be required to pay any additional amounts with respect to amounts withheld.

FATCA.  You should review the section entitled "Material U.S. Federal Income Tax Considerations—Notes Held Through Foreign Entities" in the accompanying product supplement regarding withholding rules under the “FATCA” regime. The discussion in that section is hereby modified to reflect regulations proposed by the U.S. Treasury Department indicating an intent to eliminate the requirement under FATCA of withholding on gross proceeds of the disposition of affected financial instruments. The U.S. Treasury Department has indicated that taxpayers may rely on these proposed regulations pending their finalization.

You should read the section entitled “Material U.S. Federal Income Tax Considerations” in the accompanying product supplement. The preceding discussion, when read in combination with that section, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of owning and disposing of the notes.
