Autocallable Market-Linked Step Up Notes
Linked to a Global Equity Index Basket, due December 22, 2022

Summary

The Autocallable Market-Linked Step Up Notes Linked to a Global Equity Index Basket, due December 22, 2022 (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 global equity index basket described below (the “Basket”), 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 Basket 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 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 is comprised of the EURO STOXX 50^® Index, the S&P 500^® Index and the Russell 2000^® Index. On the pricing date, each Basket Component was given an approximately equal weight.

The estimated initial value of the notes is less than the price you pay to purchase the notes. The estimated initial value was 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, reduced the economic terms of the notes (including the Call Premiums and Call Amounts). The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes.

Hypothetical Payout Profile at Maturity

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 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 Basket Components, 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 Ending Value, whether the notes are called on an Observation Date, and term of your investment.

The following table is based on the Starting Value of 100.00, the Threshold Value of 100.00, the Step Up Value of 130.00 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%
85.00	-15.00%	$8.50	-15.00%
90.00	-10.00%	$9.00	-10.00%
95.00	-5.00%	$9.50	-5.00%
100.00(1)(2)	0.00%	$13.00(3)	30.00%
105.00	5.00%	$13.00	30.00%
110.00	10.00%	$13.00	30.00%
120.00	20.00%	$13.00	30.00%
130.00(4)	30.00%	$13.00	30.00%
135.00	35.00%	$13.50	35.00%
140.00	40.00%	$14.00	40.00%
150.00	50.00%	$15.00	50.00%
160.00	60.00%	$16.00	60.00%

(1) The Starting Value was set to 100.00 on the pricing date.

(2) This is the Threshold Value.

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

(4) This is the Step Up Value.

For recent hypothetical values of the Basket, see “The Basket” section below. For recent actual levels of the Basket Components, see “The Basket Components” section below. Each Basket Component 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 any of the Basket Components, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

Risk Factors

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 Basket Components. 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.”

§ If the notes are not automatically called, depending on the performance of the Basket as measured shortly before the maturity date, you may lose up to 100% of the principal amount.

§   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.

§ 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 Basket Components.

§ 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.

§ The estimated initial value of the notes is less than the public offering price and may differ from the market value of the notes in the secondary market, if any. We determined 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 reflects 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 will 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-19, 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 value of the Basket 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.

§ 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 Basket Components), 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.

§ Changes in the level of one of the Basket Components may be offset by changes in the levels of the other Basket Components.

§ An index sponsor may adjust the relevant Basket Component 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 Basket Components, and you will not be entitled to receive securities, dividends or other distributions by issuers of those securities.

Autocallable Market-Linked Step Up Notes TS-7

Autocallable Market-Linked Step Up Notes
Linked to a Global Equity Index Basket, due December 22, 2022

§ While we, MLPF&S, BofAS or our respective affiliates may from time to time own securities of the companies included in the Basket Components, we, MLPF&S, BofAS and our respective affiliates do not control any company included in any Basket Component, and have not verified any disclosure made by any other company, except to the extent that the common stock of Bank of America Corporation (the parent company of MLPF&S & BofAS), is included in the S&P 500^® Index.

§ Your return on the notes may be affected by factors affecting the international securities markets, specifically changes within the Eurozone. The Eurozone is and has been undergoing severe financial stress and the political, legal, and regulatory ramifications are impossible to predict. Changes within the Eurozone could adversely affect the performance of the SX5E and, consequently, the value of the notes. In addition, you will not obtain the benefit of any increase in the value of the euro against the U.S. dollar, which you would have received if you had owned the securities in the SX5E during the term of your notes, although the level of the SX5E 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 us and one of which is BofAS. We have the right to appoint and remove the calculation agents.

§ 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-32 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 RTY 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.

Other Terms of the Notes

Market Measure Business Day

The following definition shall supersede and replace the definition of “Market Measure Business Day” set forth in product supplement EQUITY INDICES SUN-1.

A “Market Measure Business Day” means a day on which:

(A) each of the Eurex (as to the EURO STOXX 50^® Index) and the New York Stock Exchange and Nasdaq Stock Market, Inc. (as to the S&P 500^® Index and the Russell 2000^® Index) (or any successor to the foregoing exchanges) are open for trading; and

(B) the Basket Components or any successors thereto are calculated and published.

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 was 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.

On the pricing date, for each Basket Component, the Initial Component Weight, the closing level, the Component Ratio and the initial contribution to the Basket value were as follows:

Basket Component	Bloomberg Symbol	Initial Component Weight	Closing Level(1)	Component Ratio(2)	Initial Basket Value Contribution
EURO STOXX 50® Index	SX5E	33.34%	3,739.17	0.00891642	33.34
S&P 500® Index	SPX	33.33%	3,205.37	0.01039818	33.33
Russell 2000® Index	RTY	33.33%	1,667.094	0.01999287	33.33
				Starting Value	100.00

(1) These were the closing levels of the Basket Components on the pricing date.

(2) Each 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 the pricing date and rounded to eight decimal places.

The calculation agent will calculate the value of the Basket on each Observation Date and 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 or non-Market Measure Business Day occurs as to any Basket Component on a scheduled Observation Date or 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 is weighted by free float market capitalization. Each component’s weight is capped at 10% of the SX5E’s total free float market capitalization. Free float weights are reviewed quarterly and the SX5E’s composition is reviewed annually in September. The review cut-off date is the last trading day of August.

Within each of the 19 EURO STOXX Supersector indices, the component stocks are ranked by free float market capitalization. The largest stocks are added to the selection list until the coverage is close to, but still less than, 60% of the free float market capitalization of the corresponding EURO STOXX Total Market Index Supersector Index. If the next-ranked stock brings the coverage closer to 60% in absolute terms, then it is also added to the selection list. All current component stocks are then added to the selection list. The stocks on the selection list are ranked by free float market capitalization. In exceptional cases, the STOXX Supervisory Board may make additions and deletions to the selection list.

The 40 largest stocks on the selection list are chosen as components. The remaining 10 stocks are selected from the largest remaining current components of the SX5E that are ranked between 41 and 60. If the component number is still below 50, then the largest remaining stocks on the selection list are added until the SX5E contains 50 stocks.

Index Calculation 

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:

index =	free float market capitalization of the index
	divisor of the index

The “free float market capitalization of the index” is equal to the sum of the product of the price, number of shares, free float factor and weighting cap factor for each component stock as of the time the SX5E is being calculated.

The SX5E is also subject to a divisor, which is adjusted to maintain the continuity of index values despite changes due to corporate actions.

The following graph shows the daily historical performance of the SX5E in the period from January 1, 2009 through December 19, 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 the pricing date, the closing level of the SX5E was 3,739.17.

The S&P 500^® Index

General

The SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the SPX, discussed below in further detail, is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 500 companies as of a particular time compared to the aggregate average Market Value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

The SPX does not reflect the payment of dividends on the stocks included in the SPX and therefore the payment on the notes will not produce the same return you would receive if you were able to purchase such underlying stocks.

Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the market price of that company’s common stock is generally responsive to changes in the affairs of the respective industry and the market value and trading activity of the common stock of that company. Eleven main industry groups comprise the SPX: Communication Services, Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care, Industrials, Information Technology, Materials, Real Estate and Utilities. Changes in the SPX are reported daily in the financial pages of many major newspapers, on Bloomberg Professional^® service under the symbol “SPX” and on the S&P website. Information contained in the S&P website is not incorporated by reference in, and should not be considered a part of, this document. As of the close of business on September 21, 2018, S&P and MSCI, Inc. updated the Global Industry Classification Sector (“GICS”) structure. Among other things, the update broadened the Telecommunications Services sector and renamed it the Communication Services sector. The renamed sector includes the previously existing Telecommunication Services Industry group, as well as the Media Industry group, which was moved from the Consumer Discretionary sector and renamed the Media & Entertainment Industry group. The Media & Entertainment Industry group contains three industries: Media, Entertainment and Interactive Media & Services. The Media industry continues to consist of the Advertising, Broadcasting, Cable & Satellite and Publishing sub-industries. The Entertainment industry contains the Movies & Entertainment sub-industry (which includes online entertainment streaming companies in addition to companies previously classified in such industry prior to September 21, 2018) and the Interactive Home Entertainment sub-industry (which includes companies previously classified in the Home Entertainment Software sub-industry prior to September 21, 2018 (when the Home Entertainment Software sub-industry was a sub-industry in the Information Technology sector), as well as producers of interactive gaming products, including mobile gaming applications). The Interactive Media & Services industry and sub-industry includes companies engaged in content and information creation or distribution through proprietary platforms, where revenues are derived primarily through pay-per-click advertisements, and includes search engines, social media and networking platforms, online classifieds and online review companies. The GICS structure changes were effective for the SPX as of the open of business on September 24, 2018 to coincide with the September 2018 quarterly rebalancing.

Computation of the Index

Prior to March 2005, the Market Value of a component stock was calculated as the product of the market price per share and the total number of outstanding shares of the component stock. In March 2004, S&P announced that it would transition the SPX to float adjusted market capitalization weights. The transition began in March 2005 and was completed in September 2005. S&P’s criteria for selecting stock for the SPX were not changed by the shift to float adjustment. However, the adjustment affects each company’s weight in the SPX (i.e., its Market Value). Currently, S&P calculates the SPX based on the total float-adjusted market capitalization of each component stock, where each stock’s weight in the SPX is proportional to its float-adjusted Market Value.

Under the float adjustment, the share counts used in calculating the SPX reflect only those shares that are available to investors, not all of a company’s outstanding shares. The float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

All shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” are removed from the float for purposes of calculating the Index. Generally, these “control shareholders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float. Treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares of a U.S. company traded in Canada as “exchangeable shares” are normally part of the float unless those shares form a control block. All multiple share class companies that have listed share class lines will be adjusted for shares and float such that each share class line will only represent that line’s shares and float. The decision to include each publicly listed line is evaluated individually. All multiple share class companies that have an unlisted class line will also be adjusted.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares by the total shares outstanding. As of September 21, 2012, available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, S&P would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, S&P would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. As of July 31, 2017, companies with multiple share class lines are no longer

eligible for inclusion in the SPX. Constituents of the SPX prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the SPX. If a constituent company of the SPX reorganizes into a multiple share class line structure, that company will remain in the SPX at the discretion of the S&P Index Committee in order to minimize turnover. For companies with multiple classes of stock, S&P calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

The SPX is also calculated using a base-weighted aggregate methodology: the level of the SPX reflects the total Market Value of all the component stocks relative to the SPX base period of 1941-43. The daily index value of the SPX is the quotient of the total float-adjusted market capitalization of the SPX’s constituents and its index divisor (the “Divisor”).

Ongoing maintenance of the SPX includes monitoring and completing the adjustments for additions and deletions of the constituent companies, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spin-offs. Continuity in the level of the SPX is maintained by adjusting the Divisor for all changes in the SPX constituents’ share capital after the base date. Some corporate actions, such as stock splits and stock dividends do not require Divisor adjustments because following a stock split or stock dividend, both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the component stock. Corporate actions (such as stock splits, stock dividends, non-zero price spin-offs and rights offerings) are applied after the close of trading on the day before the ex-date.

To prevent the level of the SPX from changing due to corporate actions, all corporate actions which affect the total Market Value of the SPX also require a Divisor adjustment. By adjusting the Divisor for the change in total Market Value, the level of the SPX remains constant. This helps maintain the level of the SPX as an accurate barometer of stock market performance and ensures that the movement of the SPX does not reflect the corporate actions of individual companies in the SPX. The divisor is adjusted such that the index value at an instant just prior to a change in base capital equals the index value at an instant immediately following that change. As noted in the preceding paragraph, some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the Index and do not require Divisor adjustments.

Index maintenance adjustments will be made to account for certain corporate actions, such as addition/deletion of companies, change in shares outstanding, stock split, spin-off, change in IWF, special dividend, and rights offering. For certain index maintenance adjustments, the divisor will be adjusted and a new divisor will be calculated to account for the altered Market Value of the Index.

Another large part of the SPX maintenance process involves tracking the changes in the number of shares outstanding of each of the companies whose stocks are included in the SPX. To prevent the level of the SPX from changing due to corporate actions, corporate actions which affect the total Market Value of the SPX require a Divisor adjustment. By adjusting the Divisor for the change in Market Value, the level of the SPX remains constant and does not reflect the corporate actions of individual companies in the SPX. Divisor adjustments are made after the close of trading and after the calculation of the SPX closing level.

Changes in a company’s shares outstanding and IWF due to its acquisition of another public company are made as soon as reasonably possible. At S&P’s discretion, de minimis merger and acquisition share changes are accumulated and implemented with the quarterly share rebalancing.

All other changes of less than 5% are accumulated and made quarterly on the third Friday of March, June, September, and December.

Changes in a company’s total shares outstanding of 5% or more due to public offerings are made as soon as reasonably possible. Other changes of 5% or more (for example, due to tender offers, Dutch auctions, voluntary exchange offers, company stock repurchases, private placements, acquisitions of private companies or non-index companies that do not trade on a major exchange, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participations, at-the-market stock offerings or other recapitalizations) are made weekly, and are generally announced on Fridays for implementation after the close of trading the following Friday (one week later). If a 5% or more share change causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case-by-case basis.

The Russell 2000^® Index

FTSE Publishes the RTY

The RTY is calculated, published, and disseminated by FTSE, and measures the composite price performance of stocks of 2,000 companies determined by FTSE to be part of the U.S. equity market. All 2,000 stocks are traded on a major U.S. exchange, and form a part of the Russell 3000^® Index. The Russell 3000^® Index is composed of the 3,000 largest U.S. companies as determined by market capitalization.

The RTY consists of the smallest 2,000 companies, by market capitalization, included in the Russell 3000^® Index. The RTY is designed to track the performance of the small capitalization segment of the U.S. equity market. The inception date of the RTY is January 1, 1984. Members of the RTY are determined each year during annual reconstitution and enhanced quarterly with the addition of initial public offerings (“IPOs”). The RTY is a subset of the Russell U.S. indices.

Defining Eligible Securities

All companies that are determined to be part of the U.S. equity market under FTSE’s country-assignment methodology are included in the Russell U.S. indices. If a company is incorporated in, has a stated headquarters location in, 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 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 cross-compares the primary location of the company’s assets with the three HCIs. If the primary location of the company’s assets matches any of the HCIs, then the company is assigned to its primary asset location. If there is insufficient information to determine the country in which the company’s assets are primarily located, FTSE l will use the primary location of the company’s revenues for the same cross-comparison and will assign the company to the appropriate country in a similar fashion. FTSE uses an average of two years of assets or revenue data for analysis to reduce potential turnover. If conclusive country details cannot be derived from assets or revenue, FTSE 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 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, Curacao, 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 U.S. Virgin Islands, a U.S. HCI is assigned. If a company is designated as a Chinese “N Share,” it will not be considered for inclusion within the RTY. An “N Share” company is controlled by mainland Chinese entities, companies or individuals. It must be incorporated outside of China and traded on the New York Stock Exchange (“NYSE”), the Nasdaq exchange or the NYSE American with a majority of its revenues or assets derived from the People’s Republic of China.

All securities eligible for inclusion in the RTY must trade on an eligible U.S. exchange. The eligible U.S. exchanges are: BATS, IEX, NYSE, NYSE American, Nasdaq and ARCA. 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.

Preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights, installment receipts and trust receipts are not eligible for inclusion in the RTY. Royalty trusts, U.S. limited liability companies, closed-end investment companies, blank check companies, special-purpose acquisition companies, and limited partnerships are also not eligible for inclusion in the RTY. Business development companies, exchange traded funds and mutual funds are also excluded.

If an eligible company trades multiple share classes, FTSE will review each share class independently for U.S. index inclusion. Stocks must trade at or above $1.00 (on its primary exchange) on the rank day in May of each year to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing index member’s closing price is less than $1.00 on the last day of May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the 30 days prior to the rank date is equal to or greater than $1.00. If an existing index member does not trade on the rank day in May, it must price at $1.00 or above on another eligible U.S. exchange to remain eligible. An initial public offering added during the quarterly IPO process is considered a new index addition and therefore must have a closing price on its primary exchange at or above $1.00 on the last day of the IPO eligibility period in order to qualify for index inclusion. Companies with a total market capitalization of less than $30 million are not eligible for inclusion in the RTY. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible for the RTY.

Annual Reconstitution

Annual reconstitution is the process by which the RTY is completely rebuilt. Reconstitution is a vital part of the creation of a benchmark which accurately represents a particular market segment. Companies may get bigger or smaller over time, or periodically undergo changes in their style characteristics. Reconstitution ensures that the companies continue to be correctly represented in the RTY.

On the rank day in May each year (timetable is announced each spring), all eligible securities are ranked by their total market capitalization. Total market capitalization is determined by multiplying total outstanding shares by the last price traded on the primary exchange on the rank day in May. All share classes for a company, including unlisted shares, are aggregated and considered total shares outstanding.

Autocallable Market-Linked Step Up Notes TS-16

Autocallable Market-Linked Step Up Notes
Linked to a Global Equity Index Basket, due December 22, 2022

Reconstitution occurs on the last Friday in June. However, at times this date is too proximal to exchange closures and abbreviated exchange trading schedules when market liquidity is exceptionally low. In order to ensure proper liquidity in the markets, when the last Friday in June falls on the 29th or 30th, reconstitution will occur on the preceding Friday.

Eligible IPOs are added to the RTY quarterly to ensure that new additions to the institutional investing opportunity set are reflected in the representative indices. FTSE focuses on IPOs each quarter because it is important to reflect market additions between reconstitution periods. Companies filing an initial public offering registration statement (or the local equivalent when outside the United States) and listing with the same quarter on an eligible U.S. exchange are reviewed for eligibility regardless of previous trading activity (exceptional or unique events may induce extraordinary treatment which will be communicated appropriately); a one month window is used to ensure that companies submitting the requisite filings just outside of the quarter are not excluded from eligibility. Companies currently trading on foreign exchanges or OTC markets will be reviewed for eligibility if: (1) the company files an initial public offering statement for an eligible U.S. exchange; (2) the offering is announced to the market and confirmed by FTSE’s vendors as an IPO; and (3) the security is not currently a member of the Russell Global Index (eligibility and country assignment are reviewed at reconstitution).

Capitalization Adjustments

After membership is determined, a security’s shares are adjusted to include only those shares available to the public, which is often referred to as “free float.” The purpose of this adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set. Stocks are weighted in the RTY 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, during quarterly update cycles and for corporate actions such as mergers.

Certain types of shares are considered restricted and removed from total market capitalization to arrive at free float or available market capitalization, such as 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, and by their family and direct relations, and by companies with which they are affiliated, and shares with high shareholding concentration, etc.

Corporate Action-Driven Changes

FTSE defines a corporate action as an action on shareholders with a prescribed ex-date (e.g., rights issue, special dividend, stock split). The share price and indexes in which the company is included will be subject to an adjustment on the ex-date. This is a mandatory event. FTSE defines a corporate event as a reaction to company news (event) that might impact the index depending on the index rules. FTSE applies corporate actions and events to its indexes on a daily basis. Depending upon the time an action is determined to be final, FTSE will either (1) apply the action before the open on the ex-date, or (2) apply the action providing appropriate notice, referred to as “delayed action.”

For merger and spin-off transactions that are effective between rank day in May and the Friday prior to annual reconstitution in June, the market capitalizations of the impacted securities are recalculated and membership is reevaluated as of the effective date of the corporate action. For corporate events that occur during the final week of reconstitution (during which reconstitution is finalized Friday after U.S. market close), market capitalizations and memberships will not be reevaluated. Non index members that have been considered ineligible as of rank day will not be reevaluated in the event of a subsequent corporate action that occurs between rank day and the reconstitution effective date.

If a company distributes shares of an additional share class to its existing shareholders through a mandatory corporate action, FTSE evaluates the additional share class for separate index membership. The new share class will be deemed eligible if the market capitalization of the distributed shares meets minimum size requirement (above the minimum market capitalization breakpoint defined as the smallest member of the Russell 3000E Index from previous rebalance, adjusted for performance to date.) RTY membership of additional share classes that are added due to corporate actions will mirror that of the pricing vehicle, as will style and stability probabilities. If the distributed shares of an additional share class do not meet eligibility requirements, they will not be added to the index (the distributed shares may be added to the index temporarily until they are settled and listed to enable index replication).

“No Replacement” Rule: Securities that leave the RTY for any reason (e.g., mergers, acquisitions or other similar corporate activity) are not replaced. Thus, the number of securities in the Index over the year will fluctuate according to corporate activity. To maintain representativeness and maximize the available investment opportunity for index managers, the RTY is reviewed quarterly for updates to shares outstanding and to free floats used within the index calculation. The changes are implemented quarterly, on the third Friday of the month (after the close). The June reconstitution will continue to be implemented on the last Friday of June (unless the last Friday occurs on the 29th or 30th, when reconstitution will occur on the Friday prior).

Supplement to the Plan of Distribution

We will 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, 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 Basket, 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.

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 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 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 Basket Components, the tenor of the 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 $0.075 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.

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 Basket.

· 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.

· A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, Internal Revenue Service guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2023. Based on our determination that the notes are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the notes. However, it is possible that the notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Basket Components or the notes, and following such occurrence the notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of any Basket Component or the notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

· The discussion in the accompanying prospectus supplement under “U.S. Federal Income Tax Considerations – Foreign Account Tax Compliance Act” is hereby modified to reflect regulations proposed by the U.S. Department of Treasury indicating its intent to eliminate the requirements under FATCA of withholding on gross proceeds from the sale, exchange, settlement at maturity or other disposition of relevant financial instruments. The U.S. Department of Treasury has indicated that taxpayers may rely on these proposed regulations pending their finalization.

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-32 of product supplement EQUITY INDICES SUN-1.

Validity of the Notes

In the opinion of Mayer Brown LLP, as counsel to the issuer, when this term sheet has been attached to, and duly notated on, the master note that represents the notes pursuant to the Senior Indenture referred to in the prospectus supplement dated February 26, 2018, and issued and paid for as contemplated herein, the notes offered by this term sheet will be valid, binding and enforceable obligations of the issuer, entitled to the benefits of the Senior Indenture, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith). This opinion is given as of the date hereof and is limited to the laws of the State of New York, the Maryland General Corporation Law (including the statutory provisions, all applicable provisions of the Maryland Constitution and the reported judicial decisions interpreting the foregoing) and the federal laws of the United States of America. This opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the Senior Indenture and the genuineness of signatures and to such counsel’s reliance on the issuer and other sources as to certain factual matters, all as stated in the legal opinion dated March 1, 2018, which has been filed as Exhibit 5.4 to the issuer’s registration statement on Form S-3 dated February 26, 2018.
