The estimated initial value of the notes on the pricing date is expected to be between $8.50 and $9.50 per unit, which will be less than the public offering price listed below. The market value of the notes at any time will reflect many factors and cannot be predicted with accuracy. See “Summary” on page TS-2 and “Risk Factors” beginning on page TS-7 of this term sheet for additional information.

Neither the Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the notes or passed upon the accuracy or the adequacy of this document, the accompanying product supplement, prospectus or prospectus supplement.

Summary

The Autocallable Market-Linked Step Up Notes Linked to the S&P 500^® Index, due July , 2028 (the “notes”) are our senior unsecured debt securities and are not a direct or indirect obligation of any third party. The notes are not deposit liabilities or other obligations of a bank and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other governmental agency of the United States or any other jurisdiction. The notes will rank equally with all of our other senior unsecured debt. Any payments due on the notes, including any repayment of principal, depend on the credit risk of HSBC and its ability to satisfy its obligations as they come due. The notes will be automatically called at the applicable Call Amount if the Observation Level of the Market Measure, which is the S&P 500^® Index (the “Index”), is equal to or greater than the Call Level on the relevant Observation Date. If the notes are 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 the 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 but greater than or equal to the Threshold Value, you will receive the principal amount of your notes. If the Ending Value is less than the Threshold Value, you will lose a portion, which could be significant, 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 Index, subject to our credit risk. See “Terms of the Notes” below.

The estimated initial value of the notes will be less than the price you pay to purchase the notes. The estimated initial value is determined by reference to our or our affiliates’ internal pricing models and reflects our internal funding rate, which is the borrowing rate we pay to issue market-linked notes, and the market prices for hedging arrangements related to the notes (which may include call options, put options or other derivatives). This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. The difference in the borrowing rate, as well as the underwriting discount and the costs associated with hedging the notes, including the hedging related charge described below, will reduce the economic terms of the notes (including the Call Premiums and the Call Amounts). The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes. The estimated initial value will be calculated on the pricing date and will be set forth in the pricing supplement to which this term sheet relates.

Investor Considerations

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

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

§      You are willing to receive a return on your investment capped at the return represented by the applicable Call Premium if the relevant Observation Level is equal to or greater than the Call Level. §      You anticipate that the notes will be automatically called or that the Index will not decrease from the Starting Value to the Ending Value. §      You are willing to risk a loss of principal and return if the notes are not automatically called and the Index decreases from the Starting Value to an Ending Value that is below the Threshold Value. §      You are willing to forgo the interest payments that are paid on traditional interest bearing debt securities. §      You are willing to forgo dividends or other benefits of owning the stocks included in the Index. §      You are willing to accept that a secondary market is not expected to develop for the notes, and understand that the market prices for the notes, if any, may be less than the principal amount and will be affected by various factors, including our actual and perceived creditworthiness, our internal funding rate and the fees charged, as described on page TS-2. §      You are willing to assume our credit risk, as issuer of the notes, for all payments under the notes, including the Call Amount or the Redemption Amount.

§      You want to hold your notes for the full term. §      You believe that the notes will not be automatically called and the Index will decrease from the Starting Value to the Ending Value. §      You seek 100% principal repayment or preservation of capital. §      You seek interest payments or other current income on your investment. §      You want to receive dividends or other distributions paid on the stocks included in the Index. §      You seek an investment for which there will be a liquid secondary market. §      You are unwilling or are unable to take market risk on the notes or to take our credit risk as issuer of the notes.

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

Hypothetical Payout Profile at Maturity

The graph below is based on hypothetical numbers and values. The graph below shows 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 85% of the Starting Value, the Step Up Payment of $3.50 per unit and the Step Up Value of 135% 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.

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, Step Up Value and Ending 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 85, a Step Up Value of 135 and the Step Up Payment of $3.50 per unit. It illustrates the effect of a range of Ending Values on the Redemption Amount per unit of the notes and the total rate of return to holders of the notes. The following examples do not take into account any tax consequences from investing in the notes.

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%	$1.50	-85.00%
50.00	-50.00%	$6.50	-35.00%
75.00	-25.00%	$9.00	-10.00%
80.00	-20.00%	$9.50	-5.00%
85.00(1)	-15.00%	$10.00	0.00%
90.00	-10.00%	$10.00	0.00%
95.00	-5.00%	$10.00	0.00%
100.00(2)	0.00%	$13.50(3)	35.00%
105.00	5.00%	$13.50	35.00%
110.00	10.00%	$13.50	35.00%
120.00	20.00%	$13.50	35.00%
135.00(4)	35.00%	$13.50	35.00%
140.00	40.00%	$14.00	40.00%
150.00	50.00%	$15.00	50.00%
200.00	100.00%	$20.00	100.00%

(1) This is the hypothetical Threshold Value.

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

(3) This amount represents the sum of the principal amount and the Step Up Payment of $3.50.

(4) This is the hypothetical Step Up Value.

For recent actual levels of the Index, 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 50.00, or 50.00% of the Starting Value:
Starting Value:	100.00
Threshold Value:	85.00
Ending Value:	50.00

  Redemption Amount per unit

Example 2
The Ending Value is 95.00, or 95.00% of the Starting Value:
Starting Value:	100.00
Threshold Value:	85.00
Ending Value:	95.00
Redemption Amount per unit = $10.00, the principal amount, since the Ending Value is less than the Starting Value, but is equal to or greater than the Threshold Value.

Example 3
The Ending Value is 110.00, or 110.00% of the Starting Value:
Starting Value:	100.00
Step Up Value:	135.00
Ending Value:	110.00

$10.00 + $3.50 = $13.50 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 4
The Ending Value is 150.00, or 150.00% of the Starting Value:
Starting Value:	100.00
Step Up Value:	135.00
Ending Value:	150.00

Risk Factors

We urge you to read the section “Risk Factors” in the product supplement and in the accompanying prospectus supplement. Investing in the notes is not equivalent to investing directly in the stocks included in the Index. You should understand the risks of investing in the notes and should reach an investment decision only after careful consideration, with your advisers, with respect to the notes in light of your particular financial and other circumstances and the information set forth in this term sheet and the accompanying product supplement, prospectus supplement and prospectus.

In addition to the risks in the product supplement identified below, you should review “Risk Factors” in the accompanying prospectus supplement, including the explanation of risks relating to the notes described in the section “—Risks Relating to All Note Issuances.”

Structure-related Risks

§ If the notes are not automatically called, depending on the performance of the Index as measured shortly before the maturity date, you may lose up to 85% of the principal amount.

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

§ 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.

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

§ 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.

Valuation- and Market-related Risks

§ The estimated initial value of the notes will be less than the public offering price and may differ from the market value of the notes in the secondary market, if any. We will determine the estimated initial value by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. Different pricing models and assumptions could provide valuations for the notes that are different from our estimated initial value. The estimated initial value will reflect our internal funding rate we use to issue market-linked notes, as well as the mid-market value of the hedging arrangements related to the notes (which may include call options, put options or other derivatives).

§ Our internal funding rate for the issuance of these notes is lower than the rate we would use when we issue conventional fixed or floating rate debt securities. This is one of the factors that may result in the market value of the notes being less than their estimated initial value. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the estimated initial value of the notes may be lower if it were based on the levels at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the notes to be more favorable to you.

§ The price of your notes in the secondary market, if any, immediately after the pricing date is expected to be less than the public offering price. The public offering price takes into account certain costs, principally the underwriting discount, the hedging costs described on page TS-12 and the costs associated with issuing the notes. The costs associated with issuing the notes will be used or retained by us or one of our affiliates. If you were to sell your notes in the secondary market, if any, the price you would receive for your notes may be less than the price you paid for them.

§ The estimated initial value does not represent a minimum price at which we, MLPF&S, BofAS or any of our respective affiliates would be willing to purchase your notes in the secondary market (if any exists) at any time. The price of your notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Index and changes in market conditions, and cannot be predicted with accuracy. The notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the notes to maturity. Any sale of the notes prior to maturity could result in a loss to you.

§ A trading market is not expected to develop for the notes. None of us, MLPF&S or BofAS is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

Conflict-related Risks

§ Our business, hedging and trading activities, and those of MLPF&S, BofAS and our respective affiliates (including trades in shares of companies included in the Index), and any hedging and trading activities we, MLPF&S, 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.

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

Market Measure-related Risks

§ 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, dividends or other distributions by issuers of those securities.

§ While we, MLPF&S, BofAS or our respective affiliates may from time to time own securities of companies included in the Index, except to the extent that the common stock of Bank of America Corporation (the parent company of MLPF&S and BofAS) is included in the Index, we, MLPF&S, BofAS and our respective affiliates do not control any company included in the Index, and have not verified any disclosure made by any other company.

Tax-related Risks

§ The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes. See “Summary Tax Consequences” below and “U.S. Federal Income Tax Summary” beginning on page PS-40 of product supplement EQUITY SUN-1.

The Index

We have derived all information contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available sources.  That information reflects the policies of and is subject to change by S&P Dow Jones Indices LLC (“S&P” or the “Index sponsor”). The Index sponsor is under no obligation to continue to publish, and may discontinue or suspend the publication of, the Index at any time. 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-27 of product supplement EQUITY SUN-1. None of us, the calculation agents, MLPF&S, or BofAS accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

General

The Index was first launched on March 4, 1957 based on an initial value of 10 from 1941-1943, and it is sponsored by S&P. The Index includes a representative sample of 500 companies in leading industries of the U.S. economy. The 500 companies are not the 500 largest companies listed on the NYSE and not all 500 companies are listed on the NYSE. S&P chooses companies for inclusion in the Index with an aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the U.S. equity market. Although the Index contains 500 constituent companies, at any one time it may contain greater than 500 constituent trading lines since some companies included in the Index prior to July 31, 2017 may be represented by multiple share class lines in the Index. The Index is calculated, maintained and published by S&P and is part of the S&P Dow Jones Indices family of indices. Additional information is available on the following websites: spglobal.com/spdji/en/indices/equity/sp-500 and spglobal.com.

S&P intends for the Index to provide a performance benchmark for the large-cap U.S. equity markets. Constituent changes are made on an as-needed basis and there is no schedule for constituent reviews. Index additions and deletions are announced with at least three business days advance notice. Less than three business days’ notice may be given at the discretion of the S&P Index Committee. Relevant criteria for additions to the Index that are employed by S&P include: the company proposed for addition should have an unadjusted company market capitalization of $9.8 billion or more and a security level float-adjusted market capitalization of at least 50% of such threshold (for spin-offs, eligibility is determined using when-issued prices, if available); using composite pricing and volume, the ratio of annual dollar value traded (defined as average closing price over the period multiplied by historical volume) in the proposed constituent to float-adjusted market capitalization of that company should be at least 1.00 and the stock should trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date; the company must be a U.S. company (characterized as a Form 10-K filer with its U.S. portion of fixed assets and revenues constituting a plurality of the total and with a primary listing of the common stock on the NYSE, NYSE Arca, NYSE American, Nasdaq Global Select Market, Nasdaq Select Market, Nasdaq Capital Market, Cboe BZX, Cboe BYX, Cboe EDGA or Cboe EDGX (each, an “eligible exchange”)); the proposed constituent has an investable weight factor (“IWF”) of 10% or more; the inclusion of the company will contribute to sector balance in the Index relative to sector balance in the market in the relevant market capitalization range; financial viability (the sum of the most recent four consecutive quarters’ Generally Accepted Accounting Principles (GAAP) earnings (net income excluding discontinued operations) should be positive as should the most recent quarter); and, for IPOs, the company must be traded on an eligible exchange for at least twelve months (spin-offs or in-specie distributions from existing constituents do not need to be traded on an eligible exchange for twelve months prior to their inclusion in the Index). In addition, constituents of the S&P MidCap 400^® Index and the S&P SmallCap 600^® Index can be added to the Index provided they meet the unadjusted company level market capitalization eligibility criteria for the Index. Migrations from the S&P MidCap 400^® Index or the S&P SmallCap 600^® Index do not need to meet the financial viability, liquidity, or 50% of the Index’s unadjusted company level minimum market capitalization threshold criteria. Further, constituents of the S&P Total Market Index Ex S&P Composite 1500 (which includes all eligible U.S. common equities except for those included in the Index, the S&P MidCap 400^® Index and the S&P SmallCap 600^® Index) that acquire a constituent of the Index, the S&P MidCap 400^® Index or the S&P SmallCap 600^® Index that do not fully meet the financial viability or IWF criteria may still be added to the Index at the discretion of the Index Committee if the Index Committee determines that the addition could minimize turnover and enhance the representativeness of the Index as a market benchmark. Certain types of organizational structures and securities are always excluded, including, but not limited to, business development companies (BDCs), limited partnerships, master limited partnerships, limited liability companies (LLCs), OTC bulletin board issues, closed-end funds, ETFs, ETNs, royalty trusts, tracking stocks, special purpose acquisition companies (SPACs), preferred stock and convertible preferred stock, unit trusts, equity warrants, convertible bonds, investment trusts, rights and American depositary receipts (ADRs). Stocks are deleted from the Index when they are involved in mergers, acquisitions or significant restructurings such that they no longer meet the inclusion criteria, and when they substantially violate one or more of the addition criteria. Stocks that are delisted or moved to the pink sheets or the bulletin board are removed, and those that experience a trading halt may be retained or removed in S&P’s discretion. S&P evaluates additions and deletions with a view to maintaining Index continuity.

For constituents included in the Index prior to July 31, 2017, all publicly listed multiple share class lines are included separately in the Index, subject to, in the case of any such share class line, that share class line satisfying the liquidity and float criteria discussed above and subject to certain exceptions. It is possible that one listed share class line of a company may be included in the Index while a second listed share class line of the same company is excluded. For companies that issue a second publicly traded share class to index share class holders, the newly issued share class line is considered for inclusion if the event is mandatory and the market capitalization of the distributed class is not considered to be de minimis.

As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the Index. Only common shares are considered when determining whether a company has a multiple share class structure. Constituents of the Index prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the Index. If an Index constituent reorganizes into

a multiple share class line structure, that company will be reviewed for continued inclusion in the Index at the discretion of the S&P Index Committee.

Index Calculation

The Index is calculated using a base-weighted aggregative methodology. This discussion describes the “price return” calculation of the Index. The applicable pricing supplement will describe the calculation if the underlier for your securities is not the price return calculation. The value of the Index on any day for which an index value is published is determined by a fraction, the numerator of which is the aggregate of the market price of each stock in the Index times the number of shares of such stock included in the Index, and the denominator of which is the divisor, which is described more fully below. The “market value” of any index stock is the product of the market price per share of that stock times the number of the then-outstanding shares of such index stock that are then included in the Index.

The Index is also sometimes called a “base-weighted aggregative index” because of its use of a divisor. The “divisor” is a value calculated by S&P that is intended to maintain conformity in index values over time and is adjusted for all changes in the index stocks’ share capital after the “base date” as described below. The level of the Index reflects the total market value of all index stocks relative to the index’s base period of 1941-1943.

In addition, the Index is float-adjusted, meaning that the share counts used in calculating the Index reflect only those shares available to investors rather than all of a company’s outstanding shares. S&P seeks to exclude shares held by long-term, strategic shareholders concerned with the control of a company, a group that generally includes the following: officers and directors and related individuals whose holdings are publicly disclosed, private equity, venture capital, special equity firms, asset managers and insurance companies with board of director representation, publicly traded companies that hold shares in another company, holders of restricted shares (except for shares held as part of a lock-up agreement), company-sponsored employee share plans/trusts, defined contribution plans/savings, investment plans, foundations or family trusts associated with the company, government entities at all levels (except government retirement or pension funds), sovereign wealth funds and any individual person listed as a 5% or greater stakeholder in a company as reported in regulatory filings (collectively, “strategic holders”). To this end, S&P excludes all share-holdings (other than depositary banks, pension funds (including government pension and retirement funds), mutual funds, exchange traded fund providers, investment funds, asset managers (including hedge funds with no board of director representation), investment funds of insurance companies and independent foundations not associated with the company) with a position greater than 5% of the outstanding shares of a company from the float-adjusted share count to be used in Index calculations.

The exclusion is accomplished by calculating an IWF for each stock that is part of the numerator of the float-adjusted index fraction described above:

IWF = (available float shares)/(total shares outstanding)

where available float shares is defined as total shares outstanding less shares held by strategic holders. In most cases, an IWF is reported to the nearest one percentage point. For companies with multiple share class lines, a separate IWF is calculated for each share class line.

Index Maintenance

In order to keep the Index comparable over time S&P engages in an index maintenance process. The Index maintenance process involves changing the constituents as discussed above, and also involves maintaining quality assurance processes and procedures, adjusting the number of shares used to calculate the Index, monitoring and completing the adjustments for company additions and deletions, adjusting for stock splits and stock dividends and adjusting for other corporate actions. In addition to its daily governance of indices and maintenance of the Index methodology, at least once within any 12 month period, the S&P Index Committee reviews the Index methodology to ensure the Index continues to achieve the stated objective, and that the data and methodology remain effective. The S&P Index Committee may at times consult with investors, market participants, security issuers included in or potentially included in the Index, or investment and financial experts.

Supplement to the Plan of Distribution

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 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.

MLPF&S and BofAS may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these 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. At their discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S and BofAS may offer to buy the notes in the secondary market at a price that may exceed the estimated initial value of the notes. Any price offered by MLPF&S or BofAS for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Index, the remaining term of the notes, and the issuer’s creditworthiness. However, neither we nor any of our affiliates are 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 estimated initial value of the notes.

The value of the notes shown on your account statement provided by MLPF&S will be based on BofAS’s estimate of the value of the notes if BofAS or one of its affiliates were to make a market in the notes, which it is not obligated to do. This 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. At certain times, this price may be higher than or lower than the estimated initial 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 HSBC 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.

Role of MLPF&S and BofAS

BofAS will participate as selling agent in the distribution of the notes. 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.

Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 per unit principal amount 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 BofAS or one of its affiliates. The terms of these hedging arrangements are determined by BofAS seeking bids from market participants, which could include one of our affiliates and MLPF&S, BofAS and their affiliates. These hedging arrangements take into account a number of factors, including the issuer’s creditworthiness, interest rate movements, the volatility of the Index, the tenor of the

Autocallable Market-Linked Step Up Notes TS-12

Linked to the S&P 500^® Index, due July  , 2028

notes and the tenor of the hedging arrangements. The economic terms of the notes depend in part on the terms of the hedging arrangements.

BofAS has advised us that the hedging arrangements will include a hedging related charge of approximately $0.05 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.

Summary Tax Consequences

You should consider the U.S. federal income tax consequences of an investment in the notes, including the following:

§ There is no statutory, judicial, or administrative authority directly addressing the characterization of the notes.

§ You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the notes for all tax purposes as pre-paid executory contracts with respect to the Index.

§ Under this characterization and tax treatment of the notes, a U.S. holder (as defined in the prospectus supplement) generally will recognize capital gain or loss upon maturity or upon a sale or exchange of the notes prior to maturity. This capital gain or loss generally will be long-term capital gain or loss if you held the notes for more than one year.

§ No assurance can be given that the IRS or any court will agree with this characterization and tax treatment.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws. You should review carefully the discussion under the section entitled “U.S. Federal Income Tax Summary” beginning on page PS-40 of product supplement EQUITY SUN-1.
