HSBC USA Inc. Return Optimization Securities

Linked to the S&P 500^® Index due on or about November 30, 2015

Investment Description

These Return Optimization Securities Linked to the S&P 500^® Index (the "Index") are senior unsecured debt securities issued by HSBC USA Inc. (“HSBC”), which we refer to as the “Securities”. The Securities will rank equally with all of our other unsecured and unsubordinated debt obligations. If the Index Return is equal to or greater than zero, HSBC will repay the Principal Amount at maturity, and will pay a return equal to the Multiplier of 3.00 times the Index Return, up to the Maximum Gain, which will be set on the Trade Date and is expected to be at least 11%. If the Index Return is less than zero, HSBC will pay less than the full Principal Amount at maturity, if anything, resulting in a loss of principal that is proportionate to the negative Index Return. Investing in the Securities involves significant risks. HSBC will not pay any interest on the Securities. You may lose some or all of your Principal Amount. The stated payout from the Issuer applies if you hold the Securities to maturity. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of HSBC. If HSBC were to default on its payment obligations, you may not receive any amounts owed to you under the Securities and you could lose your entire investment.

Features

q Enhanced Growth Potential Up to the Maximum Gain: If the Index Return is greater than zero, HSBC will repay your Principal Amount at maturity plus a return equal to the Index Return multiplied by the Multiplier, up to the Maximum Gain. If the Index Return is negative, investors will be exposed to the downside market risk of the Index at maturity.

q Full Downside Market Exposure: If the Index Return is negative, investors will be exposed to the full downside performance of the Index and HSBC will pay less than the full Principal Amount at maturity, resulting in a loss of principal that is proportionate to the Index's decline.  Accordingly, you could lose some or all of the Principal Amount. Any payment on the Securities, including any repayment of principal, is subject to the creditworthiness of HSBC.

Investor Suitability

The Securities may be suitable for you if:   ¨  You fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment.   ¨  You can tolerate a loss of all or a substantial portion of your Principal Amount and are willing to make an investment that has the same downside market risk as the Index.   ¨  You believe the Index will appreciate over the term of the Securities, but will not appreciate by more than the Maximum Gain.   ¨  You understand and accept that your potential return is limited by the Maximum Gain and you would be willing to invest in the Securities if the Maximum Gain was set equal to 11% (the actual Maximum Gain will be determined on the Trade Date).   ¨  You are willing to accept the risk and return profile of the Securities versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating.   ¨  You do not seek current income from your investment and are willing to forgo dividends paid on the stocks included in the Index.   ¨  You are willing to hold the Securities to maturity and accept that there may be little or no secondary market for the Securities.   ¨  You are willing to assume the creditworthiness of HSBC, as Issuer of the Securities, and understand that if HSBC defaults on its obligations, you may not receive any amounts due to you, including any repayment of principal. The Securities may not be suitable for you if:   ¨  You do not fully understand the risks inherent in an investment in the Securities, including the risk of loss of your entire initial investment.   ¨  You cannot tolerate a loss of all or a substantial portion of your Principal Amount, and you are not willing to make an investment that has the same downside market risk as the Index.   ¨  You believe that the level of the Index will decline during the term of the Securities and is likely to close below the Initial Level on the Final Valuation Date, or you believe the Index will appreciate over the term of the Securities by more than the Maximum Gain.   ¨  You require an investment designed to provide full return of principal at maturity.   ¨  You seek an investment that participates in the full appreciation of the Index or that has unlimited returns, or you would not be willing to invest in the Securities if the Maximum Gain was set equal to 11% (the actual Maximum Gain will be determined on the Trade Date).   ¨  You prefer the lower risk, and therefore accept the potentially lower returns, of conventional debt securities with comparable maturities issued by HSBC or another issuer with a similar credit rating.   ¨  You seek current income from your investment or prefer to receive the dividends paid on the stocks included in the Index.   ¨  You are unable or unwilling to hold the Securities to maturity, or you seek an investment for which there will be an active secondary market.   ¨  You are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Securities, for any payment on the Securities, including any repayment of principal.

The suitability considerations identified above are not exhaustive. Whether or not the Securities are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the suitability of an investment in the Securities in light of your particular circumstances. You should also review “Key Risks” beginning on page 5 of this free writing prospectus and the more detailed “Risk Factors” beginning on page S-1 of the Equity Index Underlying Supplement and beginning on page S-3 of the accompanying prospectus supplement.

Investment Timeline

Key Risks

An investment in the Securities involves significant risks. Some of the risks that apply to the Securities are summarized here, but we urge you to read the more detailed explanation of risks relating to the Securities generally in the “Risk Factors” section of the accompanying Equity Index Underlying Supplement and the accompanying prospectus supplement. We also urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Securities.

¨ Your Investment in the Securities May Result in a Loss – The Securities differ from ordinary debt securities in that the Issuer will not necessarily pay the full Principal Amount of the Securities at maturity. HSBC will only pay you an amount that is equal to or greater than the Principal Amount of your Securities if the Final Level is greater than or equal to the Initial Level and only at maturity. If the Final Level is below the Initial Level, you will lose 1% of the Principal Amount for each 1% that the Final Level is less than the Initial Level. Accordingly, if the Index Return is negative, the amount of cash you receive will be less than the Principal Amount, resulting in a loss of some or all of the Principal Amount in an amount proportionate to the negative Index Return.

¨ Limited Return at Maturity – The return on the Securities at maturity is subject to the Maximum Gain. If the Index Return times the Multiplier is greater than the Maximum Gain, the return on the Securities will be limited to the Principal Amount multiplied by the Maximum Gain and you will not benefit from any further appreciation of the Index.

¨ The Multiplier Applies Only if You Hold the Securities to Maturity – You should be willing to hold your Securities to maturity. If you are able to sell your Securities prior to maturity in the secondary market, the price you receive will likely not reflect the full economic value of the Multiplier or the Securities themselves, and the return you realize may be less than three times the Index’s return, even if such return is positive and is less than the Maximum Gain. You can receive the full benefit of the Multiplier only if you hold your Securities to maturity.

¨ The Amount Payable on the Securities Is Not Linked to the Level of the Index at Any Time Other Than on the Final Valuation Date – The Final Level will be based on the Official Closing Level of the Index on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the level of the Index appreciates prior to the Final Valuation Date but then drops on the Final Valuation Date to a level that is less than the Initial Level, the Payment at Maturity will be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the level of the Index prior to such drop. Although the actual level of the Index on the Maturity Date or at other times during the term of the Securities may be higher than the Final Level, the Payment at Maturity will be based solely on the Official Closing Level of the Index on the Final Valuation Date. You may have to sell the Securities at a loss relative to your initial investment even if the level of the Index at that time is above the Initial Level.

¨ The Securities Are Subject to the Credit Risk of the Issuer –The Securities are senior unsecured debt obligations of 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 Securities 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 Securities, including any repayment 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 Securities and, in the event HSBC were to default on its obligations, you may not receive any amount owed to you under the terms of the Securities and you could lose your entire investment.

¨ The Estimated Initial Value of the Securities, Which Will Be Determined by Us on the Trade Date, May Be Less Than the Price to Public and May Differ from the Market Value of the Securities in the Secondary Market, if Any – The Estimated Initial Value of the Securities will be calculated by us on the Trade Date and may be less than the price to public. The Estimated Initial Value will reflect the internal funding rate we use to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Securities. The 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 Securities 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 Securities to be more favorable to you. We will determine the value of the embedded derivatives in the Securities 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 Securities 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 Securities in the secondary market (if any exists) at any time.

¨ The Price of Your Securities in the Secondary Market, if Any, Immediately After the Trade Date May Be Less Than the Price to Public – The price to public takes into account certain costs. These costs include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Securities and the costs associated with structuring and hedging our obligations under the Securities. 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 Securities in the secondary market, if any, the price you would receive for your Securities 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 Securities 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 Securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Securities to maturity. Any sale of the Securities prior to maturity could result in a loss to you.

5

¨ If We Were to Repurchase Your Securities Immediately After the Settlement Date, the Price You Receive May Be Higher Than the Estimated Initial Value of the Securities – Assuming that all relevant factors remain constant after the Settlement Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the Securities 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 Trade Date for a temporary period expected to be approximately five months after the Settlement 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 Securities and other costs in connection with the Securities that we will no longer expect to incur over the term of the Securities. 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 Securities and any agreement we may have with the distributors of the Securities. 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 Settlement Date of the Securities based on changes in market conditions and other factors that cannot be predicted.

¨ No Interest Payments – HSBC will not make any interest payments with respect to the Securities.

¨ Owning the Securities Is Not the Same as Owning the Stocks Comprising the Index – The return on your Securities may not reflect the return you would realize if you actually owned the stocks included in the Index. As a holder of the Securities, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the stocks included in the Index would have.

¨ The Securities Are Not Insured or Guaranteed by any Governmental Agency of the United States or any Other Jurisdiction – The Securities 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 Securities 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 Securities and you could lose your entire investment.

¨ The Securities Lack Liquidity – The Securities will not be listed on any securities exchange or quotation system. An affiliate of HSBC intends to offer to repurchase the Securities in the secondary market but is not required to do so and may cease any such market-making activities at any time without notice. Because other dealers are not likely to make a secondary market for the Securities, the price at which you may be able to trade your Securities is likely to depend on the price, if any, at which an affiliate of HSBC is willing to buy the Securities. The price, if any, will exclude any fees or commissions paid when the Securities were purchased and therefore will generally be lower than your purchase price.

¨ Changes Affecting the Index – The policies of the reference sponsor concerning additions, deletions and substitutions of the stocks included in the Index and the manner in which the reference sponsor takes account of certain changes affecting those stocks included in the Index may adversely affect the level of the Index. The policies of the reference sponsor with respect to the calculation of the Index could also adversely affect the level of the Index. The reference sponsor may discontinue or suspend calculation or dissemination of the Index. Any such actions could have an adverse effect on the value of the Securities.

¨ Potential HSBC and UBS Financial Services Inc. Impact on Price – Trading or transactions by HSBC, UBS Financial Services Inc., or any of their respective affiliates in the stocks included in the Index, or in futures, options, exchange-traded funds or other derivative products on stocks included in the Index, may adversely affect the market value of the stocks included in the Index, the level of the Index, and, therefore, the market value of the Securities.

¨ Potential Conflict of Interest – HSBC, UBS Financial Services Inc., or any of their respective affiliates may engage in business with the issuers of the stocks comprising the Index, which could affect the price of such stocks or the level of the Index and thus, may present a conflict between the obligations of HSBC and you, as a holder of the Securities.  Additionally, potential conflicts of interest may exist between the Calculation Agent, which may be HSBC or any of its affiliates, and you with respect to certain determinations and judgments that the Calculation Agent must make, which include determining the Payment at Maturity based on the Final Level as well as whether to postpone the determination of the Final Level and the Maturity Date if a Market Disruption Event occurs and is continuing on the Final Valuation Date.

¨ Potentially Inconsistent Research, Opinions or Recommendations by HSBC, UBS Financial Services Inc., or Their Respective Affiliates – HSBC, UBS Financial Services Inc., or any of their respective affiliates may publish research, express opinions or provide recommendations that are inconsistent with investing in or holding the Securities and such research, opinions or recommendations may be revised at any time. Any such research, opinions or recommendations could affect the price of the stocks included in the Index or the level of the Index, and therefore, the market value of the Securities.

¨ Market Price Prior to Maturity – The market price of the Securities will be influenced by many unpredictable and interrelated factors, including the level of the Index; the volatility of the Index; dividends paid on the stocks included in the Index; the time remaining to the maturity of the Securities; interest rates in the markets in general; geopolitical conditions and economic, financial, political, regulatory, judicial or other events; and the creditworthiness of HSBC. The stated payout from the Issuer applies if you hold the Securities to maturity and any sales prior to maturity may result in a loss even if the level of the Index is above the Initial Level at that time.

¨ Uncertain Tax Treatment – Significant aspects of the tax treatment of the Securities are uncertain. You should consult your tax advisor about your own tax situation. See “What Are the Tax Consequences of the Securities?” on page 10 of this free writing prospectus.

Scenario Analysis and Examples at Maturity

The scenario analysis and examples below are provided for illustrative purposes only and are purely hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the level of the Index relative to the Initial Level. We cannot predict the Final Level. You should not take the scenario analysis and these examples as an indication or assurance of the expected performance of the Index. The numbers set forth in the examples below have been rounded for ease of analysis. The following scenario analysis and examples illustrate the Payment at Maturity for a $10.00 Principal Amount.

The following scenario analysis and examples assume an Initial Level of 2,000.00 and a Maximum Gain of 11% (the actual Initial Level and Maximum Gain will be determined on the Trade Date), and reflect the Multiplier of 3.00.

Example 1 — The level of the Index increases from an Initial Level of 2,000.00 to a Final Level of 2,060.00. The Index Return is calculated as follows:

(2,060.00 – 2,000.00) / 2,000.00 = 3.00%

Because the Index Return is greater than zero, the Payment at Maturity for each $10.00 Principal Amount of Securities is calculated as the lesser of:

(A) $10.00 + ($10.00 × Index Return × Multiplier), and

(B) $10.00 + ($10.00 × Maximum Gain)

= the lesser of (A) $10.00 + ($10.00 × 3.00% × 3.00) and (B) $10.00 + ($10.00 × 11%)

= the lesser of (A) $10.00 + ($10.00 × 9.00%) and (B) $10.00 + ($10.00 × 11%)

= $10.00 + ($10.00 × 9.00%)

= $10.00 + $0.90

= $10.90

Because the Index Return of 3.00% multiplied by the Multiplier is less than the hypothetical Maximum Gain, at maturity, for each $10.00 Principal Amount of Securities, HSBC will pay you $10.90, resulting in a total return on the Securities of 9.00%.

Example 2 — The level of the Index increases from an Initial Level of 2,000.00 to a Final Level of 2,400.00. The Index Return is calculated as follows:

(2,400.00 – 2,000.00) / 2,000.00 = 20.00%

Because the Index Return is greater than zero, the Payment at Maturity for each $10.00 Principal Amount of Securities is calculated as the lesser of:

(A) $10.00 + ($10.00 × Index Return × Multiplier), and

(B) $10.00 + ($10.00 × Maximum Gain)

= the lesser of (A) $10.00 + ($10.00 × 20.00% × 3.00) and (B) $10.00 + ($10.00 × 11%)

= the lesser of (A) $10.00 + ($10.00 × 60.00%) and (B) $10.00 + ($10.00 × 11%)

= $10.00 + ($10.00 × 11%)

= $10.00 + $1.10

= $11.10

Because the Index Return of 20.00% multiplied by the Multiplier is greater than the hypothetical Maximum Gain, at maturity, for each $10.00 Principal Amount of Securities, HSBC will pay you $11.10, the maximum payment on the Securities, resulting in a total return on the Securities of 11%.

Example 3 — The level of the Index decreases from an Initial Level of 2,000.00 to a Final Level of 1,600.00. The Index Return is calculated as follows:

(1,600.00 – 2,000.00) / 2,000.00 = -20.00%

Because the Index Return is negative, at maturity, for each $10.00 Principal Amount of Securities HSBC will pay you an amount equal to the Principal Amount reduced by 1% for every 1% by which the Index declines, and the Payment at Maturity is calculated as follows:

   $10.00 + ($10.00 × Index Return)

= $10.00 + ($10.00 × -20.00%)

= $10.00 - $2.00

= $8.00

In this scenario, the total loss on the Securities is 20.00%.

What Are the Tax Consequences of the Securities?

You should carefully consider, among other things, the matters set forth in the section “U.S. Federal Income Tax Considerations” in the prospectus supplement. The following discussion summarizes the U.S. federal income tax consequences of the purchase, beneficial ownership and disposition of each of the Securities. This summary supplements the section “U.S. Federal Income Tax Considerations” in the 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 Securities. Under one reasonable approach, the Securities should be treated as pre-paid cash-settled executory contracts with respect to the Index. HSBC intends to treat the Securities consistent with this approach and pursuant to the terms of the Securities, you agree to treat the Securities under this approach for all U.S. federal income tax purposes. Subject to certain limitations described in the prospectus supplement, and based on certain factual representations received from HSBC, in the opinion of HSBC’s special U.S. tax counsel, Morrison & Foerster LLP, it is reasonable to treat the Securities in accordance with this approach. Pursuant to this approach, HSBC does not intend to report any income or gain with respect to the Securities prior to their maturity or an earlier sale or exchange and HSBC intends to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Security for more than one year at such time for U.S. federal income tax purposes. See "U.S. Federal Income Tax Considerations — Certain Equity-Linked Notes — Certain Notes Treated as Forward Contracts or Executory Contracts" in the prospectus supplement for the U.S. federal income tax considerations applicable to Securities that are treated as pre-paid cash-settled 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 Securities, other characterizations and treatments are possible and the timing and character of income in respect of the Securities might differ from the treatment described above. For example, the Securities 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 — U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes — Contingent Payment Debt Instruments” in the prospectus supplement.

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 Securities) 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 prospectus supplement) of the Securities is required to accrue income in respect of the Securities prior to the receipt of payments with respect to the Securities or their 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 Securities as ordinary income (including gain on a sale). Finally, it is possible that a non-U.S. holder (as defined in the prospectus supplement) of the Securities could be subject to U.S. withholding tax in respect of the Securities. It is unclear whether any regulations or other guidance would apply to the Securities (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 Securities.

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

Withholding and reporting requirements under the legislation enacted on March 18, 2010 (as discussed beginning on page S-48 of the prospectus supplement) will generally apply to payments made after June 30, 2014. However, this withholding tax will not be imposed on payments pursuant to obligations outstanding on July 1, 2014. Additionally, with respect to non-U.S. holders, withholding due to any payment being treated as a “dividend equivalent” (as discussed beginning on page S-47 of the prospectus supplement) will begin no earlier than January 1, 2016. However, the Treasury Department and IRS have announced that they intend to limit this withholding to equity-linked instruments issued on or after the date that is 90 days after the date of publication in the U.S. Federal Register of final regulations addressing dividend equivalent withholding. Holders are urged to consult with their own tax advisors regarding the possible implications of this legislation on their investment in the Securities.

PROSPECTIVE PURCHASERS OF THE SECURITIES 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 THE SECURITIES.

Historical Performance of the Index   The following graph sets forth the historical performance of the Index based on the daily historical closing levels from January 1, 2008 to October 22, 2014, as reported on the Bloomberg Professional^® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional^® service. The historical levels of the Index should not be taken as an indication of future performance.     The Official Closing Level of the Index on October 22, 2014 was 1,927.11.

Events of Default and Acceleration

If the Securities have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Securities, the Calculation Agent will determine the accelerated Payment at Maturity due and payable in the same general manner as described in “Indicative Terms” in this free writing prospectus. In that case, the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the accelerated Index Return, and the accelerated Maturity Date will be four business days after the accelerated Final Valuation Date. If a market disruption event exists on that scheduled trading day, then the accelerated Final Valuation Date will be postponed for up to five scheduled trading days (in the same general manner used for postponing the originally scheduled Final Valuation Date). The accelerated Maturity Date will also be postponed by an equal number of business days.

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

Supplemental Plan of Distribution (Conflicts of Interest)

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc., an affiliate of HSBC, will purchase the Securities from HSBC for distribution to UBS Financial Services Inc. (the “Agent”). HSBC will agree to sell to the Agent, and the Agent will agree to purchase, all of the Securities at the price indicated on the cover of the pricing supplement, the document that will be filed pursuant to Rule 424(b)(2) containing the final pricing terms of the Securities. HSBC has agreed to indemnify the Agent against liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Agent may be required to make relating to these liabilities as described in the accompanying prospectus supplement and the prospectus. The Agent may allow a concession not in excess of the underwriting commission set forth in the cover of this free writing prospectus to its affiliates.

Subject to regulatory constraints, HSBC (or an affiliate thereof) intends to offer to purchase the Securities in the secondary market, but is not required to do so. We or our affiliate will enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties, which may include the Agent, in connection with the sale of the Securities and the Agent and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the Securities, but is under no obligation to make a market in the Securities and may discontinue any market-making activities at any time without notice.
