Autocallable Market-Linked Step Up Notes
Linked to the Russell 2000^® Index, due August   , 2020

Summary

The Autocallable Market-Linked Step Up Notes Linked to the Russell 2000^® Index, due August , 2020 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other governmental agency of the United States, Switzerland or any other jurisdiction and are not secured by collateral. The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of Credit Suisse. The notes will be automatically called at the applicable Call Amount if the Observation Level of the Market Measure, which is the Russell 2000^® Index (the “Index”), is equal to or greater than the Call Level on the relevant Observation Date. If not called, at maturity, the notes provide you with a Step Up Payment if the Ending Value of the Index is equal to or greater than its Starting Value, but is not greater than the Step Up Value. If the Ending Value is greater than the Step Up Value, you will participate on a 1-for-1 basis in the increase in the level of the Index above the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

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

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This range of estimated values reflects terms that are not yet fixed and was determined based on our valuation of the theoretical components of the notes in accordance with our pricing models. These include a theoretical bond component valued using our internal funding rate, and theoretical individual option components valued using mid-market pricing. You will not have any interest in, or rights to, the theoretical components we use to determine the estimated value of the notes. The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes. The initial estimated value of the notes calculated on the pricing date will be set forth in the final term sheet made available to investors in the notes. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-13.

Hypothetical Payout Profile at Maturity

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

Autocallable Market-Linked Step Up Notes     This graph reflects the returns on the notes, based on the Threshold Value of 100% of the Starting Value, the Step Up Payment of $3.00 per unit and the Step Up Value of 130% of the Starting Value. The green line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the stocks included in the Index, excluding dividends.   This graph has been prepared for purposes of illustration only.
See below table for a further illustration of the range of hypothetical payments at maturity.

Hypothetical Payments at Maturity

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

The following table is based on a Starting Value of 100, a Threshold Value of 100, a Step Up Value of 130 and the Step Up Payment of $3.00 per unit. It illustrates the effect of a range of Ending Values on the Redemption Amount per unit of the notes and the total rate of return to holders of the notes. The following examples do not take into account any tax consequences from investing in the notes.

Ending Value	Percentage Change from the Starting Value to the Ending Value	Redemption Amount per Unit	Total Rate of Return on the Notes
0.00	-100.00%	$0.00	-100.00%
50.00	-50.00%	$5.00	-50.00%
80.00	-20.00%	$8.00	-20.00%
90.00	-10.00%	$9.00	-10.00%
100.00(1)(2)	0.00%	$13.00(3)	30.00%
110.00	10.00%	$13.00	30.00%

150.00	50.00%	$15.00	50.00%
160.00	60.00%	$16.00	60.00%

(1) The hypothetical Starting Value of 100 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value for the Market Measure.

(2) This is the hypothetical Threshold Value.

(3) This amount represents the sum of the principal amount and the Step Up Payment of $3.00.

(4) This is the hypothetical Step Up Value.

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

Redemption Amount Calculation Examples

Example 1
The Ending Value is 90.00, or 90.00% of the Starting Value:
Starting Value:	100.00
Threshold Value:	100.00

The Ending Value is 110.00, or 110.00% of the Starting Value:
Starting Value:	100.00
Step Up Value:	130.00
Ending Value:	110.00

Redemption Amount per unit, the principal amount plus the Step Up Payment, since the Ending Value is equal to or greater than the Starting Value, but less than the Step Up Value.

Example 3
The Ending Value is 140.00, or 140.00% of the Starting Value:
Starting Value:	100.00
Step Up Value:	130.00
Ending Value:	140.00

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.

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

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

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

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

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

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

§ Our internal funding rate for market-linked notes is typically lower than our secondary market credit rates, as further described in “Structuring the Notes” on page TS-13. 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-13.

§ 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-13. These factors, together with customary bid ask spreads, other transaction costs and various credit, market and economic factors over the term of the notes, including changes in the level of the Index, are expected to reduce the price at which you may be able to sell the notes in any secondary market and will affect the value of the notes in complex and unpredictable ways.

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

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

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

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

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

§ There may be potential conflicts of interest involving the calculation agents, one of which is our affiliate and one of which is MLPF&S. 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 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-30 of product supplement EQUITY INDICES SUN-1.

Additional Risk Factors

The notes are subject to risks associated with small-size capitalization companies.

The stocks composing the Index are issued by companies with small-sized market capitalization. The stock prices of small-size companies may be more volatile than stock prices of large capitalization companies. Small-size capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies. Small-size capitalization companies may also be more susceptible to adverse developments related to their products or services.

The Index

All disclosures contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation, and changes in its components, have been derived from publicly available sources. The Index was developed by Russell Investments (“Russell”) before FTSE International Limited and Russell combined in 2015 to create FTSE Russell. The information reflects the policies of, and is subject to change by, FTSE Russell (the “Index sponsor”). The Index sponsor, which licenses the copyright and all other rights to the Index, has no obligation to continue to publish, and may discontinue publication of, the Index. The consequences of the Index sponsor discontinuing publication of the Index are discussed in the section entitled “Description of the Notes—Discontinuance of an Index” beginning on page PS-22 of product supplement EQUITY INDICES SUN-1. None of us, the calculation agents, or MLPF&S accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

The Index is intended to track the performance of the small-cap segment of the U.S. equity market. The Index is reconstituted annually and eligible initial public offerings (“IPOs”) are added to the Index quarterly. The Index is a subset of the Russell 3000E^TM Index, which contains the largest 4,000 companies incorporated in the U.S. and its territories and represents approximately 99% of the U.S. equity market. The Index measures the composite price performance of stocks of approximately 2,000 U.S. companies ranked from 1,001 to 3,000 (based on descending total market capitalization) within the Russell 3000E^TM Index members. As of June 30, 2017, the largest five sectors represented by the Index were Financial Services, Health Care, Technology, Producer Durables and Consumer Discretionary. Real-time dissemination of the value of the Index by Reuters began on December 31, 1986. The Index was developed by Russell and is calculated, maintained and published by FTSE Russell. The Index is reported by Bloomberg under ticker symbol “RTY.”

Methodology for the Russell U.S. Indices

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

Preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights, installment receipts and trust receipts are not eligible for inclusion in the Russell U.S. Indices. Royalty trusts, limited liability companies, closed-end investment companies, blank check companies, special purpose acquisition companies, limited partnerships and companies that generate or have historically generated unrelated business taxable income (“UBTI”) and have not taken steps to block UBTI from equity holders are also not eligible for inclusion in the Russell U.S. Indices. Companies that are required to report acquired fund fees and expenses, business development companies, exchange-traded funds and mutual funds are excluded. Bulletin board, pink sheets, and over-the-counter (“OTC”) traded securities are not eligible for inclusion, including securities for which prices are displayed on the FINRA ADF. Stocks must trade at or above $1.00 on their primary exchange on the rank day in May to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing member’s closing price is less than $1.00 on the rank day in May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the 30 days prior to the rank day is equal to or greater than $1.00. Initial public offerings must have a closing price at or above $1.00 on the last day of their eligibility period in order to qualify for index inclusion. If a stock, new or existing, does not have a closing price at or above $1.00 (on its primary exchange) on the rank day in May, but does have a closing price at or above $1.00 on another major U.S. exchange, that stock will be eligible for inclusion. Companies with a total market capitalization of less than $30 million are not eligible. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible. When unavailable shares are determined to be 94.5% or greater, this will be rounded to 95%.

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

Common stock, non-restricted exchangeable shares that may be exchanged at any time at the holder’s option on a one-for-one basis for common stock, and partnership units/membership interests (in certain cases, described below) are used to determine market capitalization for a company. FTSE Russell includes membership or partnership units/interests as part of total market capitalization when the company in question is merely a holding company of an underlying entity that issues membership or partnership units/interests and these units are the company’s sole assets. If multiple share classes of common stock exist, they are combined. In cases where the common stock share classes act independently of each other, each class is considered for inclusion separately.

Stapled units and other paired share structures are considered eligible for index inclusion, unless an underlying component of the stock is an ineligible security type (e.g., convertible debt). On the rank day in May of each year, all eligible securities are ranked by their total market capitalization. Reconstitution occurs on the last Friday in June. However, at times this date precedes a long U.S. holiday weekend, when liquidity is low. In order to ensure proper liquidity in the markets, when the last Friday in June is the 29th or 30th, reconstitution will occur on the preceding Friday. In addition, FTSE Russell adds initial public offerings on a quarterly basis based on market capitalization guidelines established during the most recent reconstitution.

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

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

Float Adjustments

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

Effective June 2017, the following types of shares are considered unavailable for purchase and removed from total market capitalization to arrive at free float or available market capitalization:

§ Shares directly owned by state, regional, municipal and local governments (excluding shares held by independently managed pension schemes for governments)

§ Shares held by directors, senior executives and managers of the company, by their family and direct relations and by companies with which they are affiliated*

§ Shares held within employee share plans

§ Shares held by public companies or by non-listed subsidiaries of public companies

§ All shares where the holder is subject to a lock-in clause (for the duration of that clause)**

§ Shares held by an investor, investment company or an investment fund that is actively participating in the management of a company or is holding shares in a company for strategic reasons as evidenced by specific statements to that effect in publicly available announcements, or has successfully placed a current member to the board of directors of a company

§ Shares that are subject to ongoing contractual agreements (such as swaps) where they would ordinarily be treated as restricted

* For the analysis of US company free float, holdings of options, warrants and convertibles will be removed from the officer and director holdings when those shares are provided in a summed format within the footnotes of the SEC filings. Where FTSE Russell determines that a company is being excluded from index membership solely on the basis of the minimum float requirement, FTSE Russell will use the best available information contained in the SEC filings to determine the free float.

** Free float changes resulting from the expiry of a lock-in will be implemented at the next quarterly review subsequent to there being a minimum of 20 business days between the lock-in expiry date and the Tuesday before the first Friday of the review month. If the previously locked-in shares are sold by way of a corporate event (such as a secondary offering), any change to the free float will be applied T+2 following completion and will not be subject to the minimum 20 business day rule.

Corporate Actions and Events Affecting a Russell U.S. Index

Depending upon the time an event is determined to be final, FTSE Russell will either (1) apply the event before the open on the ex-date, or (2) apply the event providing appropriate notice if it is deemed to be “actionable” for passive index managers. The timing of when corporate actions and events are applied is critical for accurate market representation, and how it impacts tracking for passive managers. The impact of the event and the effective date will be communicated to clients on a regular schedule, via the daily corporate actions and events deliverables. A full description of all corporate action driven change to the Russell U.S. Indices can be found on FTSE Russell’s website.

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 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; 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 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 supplements, the discussion under the section entitled “Material U.S. Federal Income Tax Considerations” beginning on page PS-30 of product supplement EQUITY INDICES SUN-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 will be long-term capital gain or loss in the case of a U.S. Holder that has held the note for more than one year at settlement or maturity and short-term capital gain or loss otherwise.

Substitute Dividend and Dividend Equivalent Payments

Based on the terms of the notes and representations provided by us, our counsel is of the opinion that a note (exclusive of any other transactions that may be combined with the note as discussed in the product supplement) should not be a “delta-one transaction” with respect to a specified ELI or specified NPC within the meaning of the regulations and, as a result, we will not treat the note as a section 871(m) transaction. If withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld.

Where You Can Find More Information

We have filed a registration statement (including a product supplement, a prospectus supplement, and a prospectus) with the SEC for the offering to which this term sheet relates. Before you invest, you should read the Note Prospectus, including this term sheet, and the other documents that we have filed with the SEC, for more complete information about us and this offering.
