Summary

The four charts below provide a summary of the Notes, including Note characteristics and risk considerations, as well as an illustrative diagram and table reflecting hypothetical returns on the Notes.   These charts should be reviewed together with the other information contained in this free writing prospectus as well as in the accompanying prospectus and prospectus supplement.

The following charts illustrate the hypothetical total return on the Notes. The “total return” as used in this free writing prospectus is the number, expressed as a percentage, that results from comparing the payment on the Notes upon a call or at maturity per $1,000 in Principal Amount to $1,000. The hypothetical total returns set forth below assume an Initial Price of $100.00 and the Contingent Coupon of $35.50 for each applicable Coupon Payment Date. The hypothetical total returns set forth below are for illustrative purposes only, and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following table and examples have been rounded for ease of analysis.

Selected Purchase Considerations

· CONTINGENT COUPON PAYMENT— HSBC will pay a quarterly Contingent Coupon payment on a Coupon Payment Date if the Official Closing Price of the Reference Asset on the applicable Observation Date or the Final Price is equal to or greater than the Coupon Barrier. Otherwise, no coupon will be paid on such Coupon Payment Date. The expected Coupon Payment Dates are November 24, 2015, February 23, 2015, May 24, 2015 and August 24, 2016 (which is also the expected Maturity Date). For information regarding the record dates applicable to the Coupons paid on the Notes, please see the section entitled “Recipients of Interest Payments” on page S-12 in the accompanying prospectus supplement. The Contingent Coupon Rate is 14.20% per annum, payable in equal quarterly installments. The actual Contingent Coupon Rate will be determined on the Trade Date.

· AUTOMATIC CALL FEATURE — The Notes will be automatically called if the Official Closing Price on any Observation Date is at or above the Initial Price. If the Notes are automatically called, you will receive, on the applicable Call Payment Date, a cash payment per $1,000 Principal Amount of Notes equal to the Principal Amount plus the Contingent Coupon.

· TAX TREATMENT — You should carefully consider, among other things, the matters set forth in the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement. The following discussion summarizes certain of the material U.S. federal income tax consequences of the purchase, beneficial ownership, and disposition of each of the Notes. This summary supplements the section “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement and supersedes it to the extent inconsistent therewith.

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes. Under one reasonable approach, the Notes should be treated as contingent income-bearing pre-paid executory contracts with respect to the Reference Asset. We intend to treat the Notes consistent with this approach, and pursuant to the terms of the Notes, you agree to treat the Notes under this approach for all U.S. federal income tax purposes. Subject to certain limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Morrison & Foerster LLP, it is reasonable to treat the Notes in accordance with this approach. Pursuant to this approach, we intend to treat any gain or loss upon maturity or an earlier sale, exchange or call as capital gain or loss in an amount equal to the difference between the amount you receive at such time (other than with respect to a Contingent Coupon) and your tax basis in the Note. Any such gain or loss will be long-term capital gain or loss if you have held the Note for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a Note generally will equal your cost of the Note. In addition, the tax treatment of the Contingent Coupons is unclear. Although the tax treatment of the Contingent Coupons is unclear, we intend to treat any Contingent Coupon, including on the Maturity Date or upon automatic call, as ordinary income includible in income by you at the time it accrues or is received in accordance with your normal method of accounting for U.S. federal income tax purposes. See “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated as Executory Contracts” in the accompanying prospectus supplement for the U.S. federal income tax considerations applicable to securities that are treated as income-bearing pre-paid executory contracts.

Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes, other characterizations and treatments are possible and the timing and character of income in respect of the Notes might differ from the treatment described above. For example, the Notes could be treated as debt instruments that are “contingent payment debt instruments” for U.S. federal income tax purposes subject to the treatment described under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes — Contingent Notes” in the accompanying prospectus supplement.

In addition, if you are a non-U.S. holder (as defined in the accompanying prospectus supplement), because the U.S. federal income tax treatment of the Contingent Coupons (including the applicability of withholding) is unclear, the entire amount of the Contingent Coupons will be subject to U.S. federal income tax withholding at a 30% rate (or at a lower rate under an applicable income tax treaty). We will not pay any additional amounts in respect of such withholding.

In Notice 2008-2, the Internal Revenue Service (“IRS”) and the Treasury Department requested comments as to whether the purchaser of an exchange traded note or pre-paid forward contract (which may include the Notes) should be required to accrue income during its term under a mark-to-market, accrual or other methodology, whether income and gain on such a note or contract should be ordinary or capital, and whether foreign holders should be subject to withholding tax on any deemed income accrual. Accordingly, it is possible that regulations or other guidance could provide that a U.S. holder (as defined in the accompanying prospectus supplement) of a Note is required to accrue income in respect of the Notes prior to the receipt of payments with respect to the Notes or their

-4-

earlier sale. Moreover, it is possible that any such regulations or other guidance could treat all income and gain of a U.S. holder in respect of the Notes as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder of the Notes could be subject to U.S. withholding tax in respect of the Notes. It is unclear whether any regulations or other guidance would apply to the Notes (possibly on a retroactive basis). Prospective investors are urged to consult with their tax advisors regarding Notice 2008-2 and the possible effect to them of the issuance of regulations or other guidance that affects the U.S. federal income tax treatment of the Notes.

We will not attempt to ascertain whether the Reference Asset Issuer would be treated as a passive foreign investment company (“PFIC”) or a United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If the Reference Asset Issuer were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC by the Reference Asset Issuer and consult your tax advisor regarding the possible consequences to you if the Reference Asset Issuer is or becomes a PFIC or a USRPHC.

PROSPECTIVE PURCHASERS OF NOTES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE U.S. FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF NOTES.

Selected Risk Considerations

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Reference Asset. These risks are explained in more detail in the “Risk Factors” sections of the accompanying Stock-Linked Underlying Supplement and prospectus supplement.

· SUITABILITY OF THE NOTES FOR INVESTMENT — You should only reach a decision to invest in the Notes after carefully considering, with your advisors, the suitability of the Notes in light of your investment objectives and the information set out in this free writing prospectus. Neither HSBC nor any dealer participating in the offering makes any recommendation as to the suitability of the Notes for investment.

· YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — The Notes do not guarantee any return of principal. The return on the Notes is linked to the performance of the Reference Asset, and will depend on whether the Official Closing Price of the Reference Asset on the Observation Dates or the Final Price, as applicable, is at or above the Coupon Barrier or Trigger Price. If the Notes are not called, HSBC will only pay you the Principal Amount of your Securities (plus the final Contingent Coupon) if the Final Price is greater than or equal to the Trigger Price and will only make such payment at maturity. If the Notes are not called and the Final Price is less than the Trigger Price, you will lose some or all of your initial investment in an amount proportionate to the decline in the Final Price from the Initial Price.

· THE AMOUNT PAYABLE ON THE NOTES IS NOT LINKED TO THE PRICE OF THE REFERENCE ASSET AT ANY TIME OTHER THAN ON THE OBSERVATION DATES AND THE FINAL VALUATION DATE — The Final Price will be based on the Official Closing Price of the Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the price of the Reference Asset appreciates during the term of the Notes other than on the Final Valuation Date but then drops on the Final Valuation Date to a price that is less than the Initial Price, the Payment at Maturity may be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the price of the Reference Asset prior to such decrease. Although the actual price of the Reference Asset on the Maturity Date or at other times during the term of the Notes may be higher than the Final Price, the Payment at Maturity will be based solely on the Official Closing Price of the Reference Asset on the Final Valuation Date. Similarly, whether your Notes are subject to an automatic call will depend on the Official Closing Price on the Observation Dates. If the Official Closing Price is less than the Trigger Price on any Observation Date, your notes will not be called, even if the Official Closing Price is higher than the Trigger Price at other times during the term of the Notes. As a result, it is possible that your Payment at Maturity may be less than 100% of the principal amount if the Final Price is less than the Trigger Price.

· You May Not Receive any Contingent Coupons — HSBC will not necessarily make periodic coupon payments on the Notes. If the Official Closing Price of the Reference Asset on an Observation Date or the Final Price is less than the Coupon Barrier, HSBC will not pay you the Contingent Coupon applicable to such Observation Date or the Final Valuation Date, as applicable. If the Official Closing Price of the Reference Asset on each of the Observation Dates (and the Final Price) is less than the Coupon Barrier, HSBC will not pay you any Contingent Coupons during the term of, and you will not receive a positive return on, your Notes. Generally, this non-payment of the Contingent Coupon coincides with a period of greater risk of principal loss on your Notes.

· REINVESTMENT RISK — If your Notes are automatically called, the term of the Notes may be as short as approximately three months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are automatically called prior to the maturity date.

· THE NOTES ARE SUBJECT TO THE CREDIT RISK OF HSBC USA INC. — The Notes are senior unsecured debt obligations of the Issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the Notes will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the Notes, including any return of principal at maturity, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the Notes and, in the event HSBC were to default on its obligations, you may not receive the amounts owed to you under the terms of the Notes.

· YOUR RETURN ON THE NOTES IS LIMITED TO THE PRINCIPAL AMOUNT PLUS THE CONTINGENT COUPONS, IF ANY, REGARDLESS OF ANY APPRECIATION IN THE VALUE OF THE REFERENCE ASSET — If the Notes are not automatically called, for each $1,000 principal amount Note, you will receive $1,000 at maturity plus the Contingent Coupon if the Final Price of the Reference Asset is equal to or greater than the Trigger Price (and Coupon Barrier), regardless of any appreciation in the value of the Reference Asset, which may be significant.

-6-

Additionally, if the Notes are automatically called, you will not receive any Contingent Coupon payments for periods after which the Notes are called. Accordingly, the return on the Notes may be significantly less than the return on a direct investment in the Reference Asset during the term of the Notes.

· Potentially Inconsistent Research, Opinions or Recommendations by HSBC and JPMorgan — HSBC, JPMorgan, or their respective affiliates may publish research, express opinions or provide recommendations that are inconsistent with investing in or holding the Notes and which may be revised at any time. Any such research, opinions or recommendations could affect the price of the Reference Asset, and therefore, the market value of the Notes.

· THE ESTIMATED INITIAL VALUE OF THE NOTES, WHICH WILL BE DETERMINED BY US ON THE PRICING DATE, WILL BE LESS THAN THE PRICE TO PUBLIC AND MAY DIFFER FROM THE MARKET VALUE OF THE NOTES IN THE SECONDARY MARKET, IF ANY — The Estimated Initial Value of the Notes will be calculated by us on the Pricing Date and will be less than the price to public. The Estimated Initial Value will reflect our internal funding rate, which is the borrowing rate we pay to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. 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. We will determine the value of the embedded derivatives in the Notes 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. Different pricing models and assumptions could provide valuations for the Notes that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our 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, IMMEDIATELY AFTER THE PRICING DATE WILL BE LESS THAN THE PRICE TO PUBLIC — The price to public takes into account certain costs. These costs will include our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes, the underwriting discount and the costs associated with structuring and hedging our obligations under the Notes. These costs, except for the underwriting discount, 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 because secondary market prices will not take into account these costs. The price of your Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the price of the Reference Asset 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.

· IF HSBC SECURITIES (USA) INC. WERE TO REPURCHASE YOUR NOTES IMMEDIATELY AFTER THE ORIGINAL ISSUE DATE, THE PRICE YOU RECEIVE MAY BE HIGHER THAN THE ESTIMATED INITIAL VALUE OF THE NOTES — Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed the Estimated Initial Value on the Pricing Date for a temporary period expected to be approximately three months after the Original Issue Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes that we will no longer expect to incur over the term of the Notes. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the Notes and any agreement we may have with the distributors of the Notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

· There is limited anti-dilution protection — The Calculation Agent will adjust the Official Closing Price, for certain events affecting the shares of the Reference Asset, such as stock splits and corporate actions which may affect the price of the Reference Asset. The Calculation Agent is not required to make an adjustment for every corporate action which affects the shares of the Reference Asset. If an event occurs that does not require the Calculation Agent to adjust the price of the shares of the Reference Asset, the market price of the Notes and the Payment at Maturity may be materially and adversely affected. See the section “Additional Terms of the Notes—

-7-

Antidilution and Reorganization Adjustments” in the accompanying Stock-Linked Underlying Supplement for additional information.

· NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the Notes, you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of shares of the Reference Asset would have. In addition, the Reference Asset Issuer will not have any obligation to consider your interests as a holder of the Notes in taking any corporate action that might affect the value of the Reference Asset and the Notes.

· WE ARE NOT AFFILIATED WITH THE REFERENCE ASSET ISSUER— We are not affiliated with the Reference Asset Issuer. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information about the Reference Asset contained in this free writing prospectus. You should make your own investigation into the Reference Asset and the Reference Asset Issuer. We are not responsible for the Reference Asset Issuer’s public disclosure of information, whether contained in SEC filings or otherwise.

· In some circumstances, the payment you receive on the Notes may be partially based on the common stock of a company other than the reference asset— Following certain corporate events relating to the Reference Asset Issuer where such issuer is not the surviving entity, your Payment at Maturity may be based on the common stock of a successor to the respective Reference Asset Issuer or any cash or any other assets distributed to holders of the Reference Asset in such corporate event. The occurrence of these corporate events and the consequent adjustments may materially and adversely affect the value of the Notes. For more information, see the “Additional Terms of the Notes—Antidilution and Reorganization” in the accompanying Stock-Linked Underlying Supplement.

· THE NOTES LACK LIQUIDITY — The Notes will not be listed on any securities exchange. HSBC Securities (USA) Inc. may offer to purchase the Notes in the secondary market. However, it is not required to do so and may cease making such offers at any time, if at all. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the Notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily.

· POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the Notes, including acting as Calculation Agent and hedging our obligations under the Notes. In performing these duties, the economic interests of us and our affiliates are potentially adverse to your interests as an investor in the Notes. We will not have any obligation to consider your interests as a holder of the Notes in taking any corporate actions or other actions that might affect the price of the Reference Asset and the value of the Notes.

· The Notes are Not Insured OR GUARANTEED by any Governmental Agency of the United States or any Other Jurisdiction — The Notes are not deposit liabilities or other obligations of a bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency or program of the United States or any other jurisdiction. An investment in the Notes is subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations as they become due, you may not receive the full Payment at Maturity of the Notes.

· HISTORICAL PERFORMANCE OF THE REFERENCE ASSET SHOULD NOT BE TAKEN AS AN INDICATION OF ITS FUTURE PERFORMANCE DURING THE TERM OF THE NOTES — It is impossible to predict whether the price of the Reference Asset will rise or fall. The Reference Asset will be influenced by complex and interrelated political, economic, financial and other factors.

· MARKET DISRUPTIONS MAY ADVERSELY AFFECT YOUR RETURN — The Calculation Agent may, in its sole discretion, determine that the markets have been affected in a manner that prevents it from determining the Reference Asset in the manner described herein, and calculating the amount that we are required to pay you upon maturity, or from properly hedging its obligations under the Notes. These events may include disruptions or suspensions of trading in the markets as a whole. If the Calculation Agent, in its sole discretion, determines that any of these events prevents us or any of our affiliates from properly hedging our obligations under the Notes or prevents the Calculation Agent from determining the Reference Return or Payment at Maturity in the ordinary manner, the Calculation Agent will determine the Reference Return or Payment at Maturity in good faith and in a commercially reasonable manner, and it is possible that the Final Valuation Date and the Maturity Date will be postponed, which may adversely affect the return on your Notes.

· MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES — In addition to the price of the Reference Asset on any day, the value of the Notes will be affected by a number of economic and market factors that may either offset or magnify each other, including:

· the actual and expected volatility of the Reference Asset;

· the time to maturity of the Notes;

· the dividend rate on the Reference Asset;

· interest and yield rates in the market generally;

· a variety of economic, financial, political, regulatory or judicial events that affect the Reference Asset or the securities markets generally; and

· our creditworthiness, including actual or anticipated downgrades in our credit ratings.

Hypothetical Examples

The below scenario analysis and examples are hypothetical and provided for illustrative purposes only. They do not purport to be representative of every possible scenario concerning increases or decreases in the price of the Reference Asset relative to its Initial Price. We cannot predict the Final Price or the Official Closing Price of the Reference Asset on any Observation Date. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Reference Asset. The following scenario analysis and examples illustrate the Payment at Maturity per $1,000.00 Note on a hypothetical offering of the Notes, based on the following assumptions (the actual Initial Price, Coupon Barrier and Trigger Price for the Notes will be determined on the Pricing Date):

Hypothetical Initial Price:	$100.00
Contingent Coupon Rate:	14.20%, payable in equal quarterly installments.
Contingent Coupon:	$35.50 for each applicable Coupon Payment Date
Observation Dates:	Quarterly
Hypothetical Coupon Barrier:	$70.00 (which is equal to 70% of the Hypothetical Initial Price)
Hypothetical Trigger Price:	$70.00 (which is equal to 70% of the Hypothetical Initial Price)

Example 1 — The Notes are called on the first Observation Date

Date	Official Closing Price	Payment (per Security)
First Observation Date	$130.00 (at or above Initial Price)	$1,035.50 (Payment at Redemption)
	Total Payment: $1,035.50 (3.55% return)

Since the Notes are called on the first Observation Date, HSBC will pay you on the applicable Call Settlement Date a total of $1,035.50 per $1,000 Note, reflecting your Principal Amount plus the Contingent Coupon of $35.50. The total return on the Notes would be 3.55%. No further amount will be owed to you under the Notes.

Example 2 — The Notes are NOT called on any of the Observation Dates and the Final Price of the Reference Asset is greater than or equal to the Trigger Price

Dates	Official Closing Price/Final Price	Payment (per Security)
First Observation Date	$90.00 (at or above Coupon Barrier; below Initial Price)	$35.50 (Contingent Coupon)
Second Observation Date	$87.00 (at or above Coupon Barrier; below Initial Price)	$35.50 (Contingent Coupon)
Third Observation Date	$85.00 (at or above Coupon Barrier; below Initial Price)	$35.50 (Contingent Coupon)
Final Valuation Date	$140.00 (at or above Trigger Price and Coupon Barrier; below Initial Price)	$1,035.50 (Payment at Maturity)
	Total Payment: $1,142.00 (14.20% return)

Since the Notes are not called and the Final Price of the Reference Asset is above the Trigger Price, HSBC will pay you a total of $1,035.50 at maturity per $1,000 Note, reflecting your Principal Amount plus the Contingent Coupon of $35.50. When added to the Contingent Coupon payments of $35.50 received in respect of each of the three Observation Dates, HSBC will have paid you a total of $1,142.00 per $1,000 Note. The total return on the Notes would be 14.20%.

Example 3 — The Notes are NOT called on any of the Observation Dates and the Final Price of the Reference Asset is below the Trigger Price

Dates	Official Closing Price/Final Price	Payment (per Security)
First Observation Date	$90.00 (at or above Coupon Barrier; below Initial Price)	$35.50 (Contingent Coupon)
Second Observation Date	$87.00 (at or above Coupon Barrier; below Initial Price)	$35.50 (Contingent Coupon)
Third Observation Date	$85.00 (at or above Coupon Barrier; below Initial Price)	$35.50 (Contingent Coupon)
Final Valuation Date	$70.00 (below Trigger Price and Coupon Barrier)	$1,000 × (1 + Reference Return) =
		$1,000 × (1 + -30.00%) =
		$1,000 - $300.00 =
		$700.00 (Payment at Maturity)
	Total Payment $806.50 (-19.35% return)

Since the Notes are not called and the Final Price of the Reference Asset is below the Trigger Price, HSBC will pay you a total of $700.00 at maturity per $1,000 Note. When added to the Contingent Coupon payments of $35.50 received in respect of each of the three Observation Dates, HSBC will have paid you $806.50 per $1,000 Note. The total loss on the Notes would be 19.35%.

Events of Default and Acceleration

If the Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Notes, the Calculation Agent will determine the accelerated Payment at Maturity due and payable in the same general manner as described in “Key Terms” in this free writing prospectus. In that case, the trading day preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the accelerated Reference Return (including the Final Price). The accelerated Maturity Date will be the third business day following the postponed accelerated Final Valuation Date.

If the Notes have become immediately due and payable following an event of default, you will not be entitled to any additional payments with respect to the Notes. For more information, see “Description of Debt Securities — Senior Debt Securities — Events of Default” in the accompanying prospectus.
