The Autocallable Contingent Income Barrier Notes (each a “Note” and collectively the “Notes”) offered hereunder will not be listed on any securities exchange or automated quotation system.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the Notes or passed upon the accuracy or the adequacy of this document, the accompanying prospectus, prospectus supplement or ETF Underlying Supplement. Any representation to the contrary is a criminal offense.

We have appointed HSBC Securities (USA) Inc., an affiliate of ours, as the agent for the sale of the Notes. HSBC Securities (USA) Inc. will purchase the Notes from us for distribution to other registered broker-dealers or will offer the Notes directly to investors. In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use this pricing supplement in market-making transactions in any Notes after their initial sale. Unless we or our agent inform you otherwise in the confirmation of sale, this pricing supplement is being used in a market-making transaction. See “Supplemental Plan of Distribution (Conflicts of Interest)” on page PS-19 of this document.

Investment in the Notes involves certain risks. You should refer to “Risk Factors” beginning on page PS-7 of this document, page S-1 of the accompanying prospectus supplement and page S-1 of the accompanying ETF Underlying Supplement.

The Estimated Initial Value of the Notes on the Pricing Date is $962.80 per Note, which is less than the price to public. The market value of the Notes at any time will reflect many factors and cannot be predicted with accuracy. See “Estimated Initial Value” on page PS-3 and “Risk Factors” beginning on page PS-7 of this document for additional information.

⁽¹⁾ HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 1.75% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers.

Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and ETF Underlying Supplement if you request them by calling toll-free 1-866-811-8049.

If the Official Closing Price of each Underlying is at or above its Call Threshold on any Call Observation Date the Notes will be automatically called, and you will receive a cash payment, per $1,000 Principal Amount, equal to the Principal Amount plus the applicable Contingent Coupon on the corresponding Call Payment Date.

We will pay a quarterly Contingent Coupon payment on a Coupon Payment Date if the Official Closing Price of each Underlying on the applicable Observation Date is greater than or equal to its Coupon Trigger. Otherwise, no coupon will be paid on such Coupon Payment Date. For information regarding the record dates applicable to the Contingent Coupons payable on the Notes, please see the section entitled “Description of Notes—Interest and Principal Payments—Recipients of Interest Payments” beginning on page S-14 in the accompanying prospectus supplement. The Contingent Coupon Rate is 13.48% per annum (or $33.70 per $1,000 Principal Amount per quarter, if payable).

Unless the Notes are called, on the Maturity Date and for each $1,000 Principal Amount, you will receive a cash payment equal to the Final Settlement Value determined as follows:

n If the Reference Return of the Least Performing Underlying is greater than or equal to -30.00%:

n If the Reference Return of the Least Performing Underlying is less than -30.00%:

If the Notes are not called and the Final Value of the Least Performing Underlying is less than its Barrier Value, you will not receive the final Contingent Coupon, and will lose up to 100% of the Principal Amount. Even with any Contingent Coupons received prior to maturity, your return on the Notes may be negative in this case.

We or one of our affiliates will act as calculation agent with respect to the Notes.

The reference Ssponsor of the KRE is PDR Services, LLC. The reference sponsor of the XBI is the Select Sector SPDR Trust. The reference sponsor of the XLK is the Select Sector SPDR Trust.

The Notes may be suitable for you if:

You believe that the Official Closing Price of each Underlying will be at or above its Coupon Trigger on most or all of the Observation Dates, and the Final Value of the Least Performing Underlying will be at or above its Barrier Value.

You seek a quarterly Contingent Coupon, based on the performance of the Underlyings, that will be paid at the Contingent Coupon Rate of 13.48% per annum if the Official Closing Price of each Underlying is greater than or equal to its Coupon Trigger on the applicable Observation Date.

You are willing to invest in the Notes based on the fact that your maximum potential return is limited to any Contingent Coupons payable on the Notes.

You do not seek an investment that provides an opportunity to participate in the appreciation of the Underlyings.

You are willing to make an investment that is exposed to the potential downside performance of the Least Performing Underlying on a 1-to-1 basis if the Notes are not called and the Reference Return of the Least Performing Underlying is less than -30.00%.

You are willing to lose up to 100% of the Principal Amount.

You are willing to hold the Notes which will be automatically called on any Call Observation Date on which the Official Closing Price of each Underlying is at or above its Call Threshold, or you are otherwise willing to hold the Notes to maturity.

You are willing to forgo guaranteed interest payments on the Notes, and the dividends or other distributions paid on the stocks included in the Underlyings.

You do not seek an investment for which there will be an active secondary market.

You are willing to accept the risk and return profile of the Notes versus a conventional debt security with a comparable maturity issued by HSBC or another issuer with a similar credit rating.

You are comfortable with the creditworthiness of HSBC, as Issuer of the Notes.

The Notes may not be suitable for you if:

You believe that the Official Closing Price of at least one Underlying will be below its Coupon Trigger on most or all of the Observation Dates, including the Final Valuation Date, and the Final Value of the Least Performing Underlying will be below its Barrier Value.

You believe that the Contingent Coupon, if any, will not provide you with your desired return.

You are unwilling to invest in the Notes based on the fact that your maximum potential return is limited to any Contingent Coupons payable on the Notes.

You seek an investment that provides an opportunity to participate in the appreciation of the Underlyings.

You are unwilling to make an investment that is exposed to the potential downside performance of the Least Performing Underlying on a 1-to-1 basis if the Notes are not called and the Reference Return of the Least Performing Underlying is less than -30.00%.

You seek an investment that provides full return of principal at maturity.

You are unable or unwilling to hold Notes that will be automatically called on any Call Observation Date on which the Official Closing Price of each Underlying is at or above its Call Threshold, or you are otherwise unable or unwilling to hold the Notes to maturity.

You prefer to receive guaranteed periodic interest payments on the Notes, or the dividends or other distributions paid on the stocks included in the Underlyings.

You seek an investment for which there will be an active secondary market.

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 are not willing or are unable to assume the credit risk associated with HSBC, as Issuer of the Notes.

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page S-1 of the accompanying ETF Underlying Supplement. You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this document, and the accompanying prospectus, prospectus supplement and ETF Underlying Supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and ETF Underlying Supplement including the explanation of risks relating to the Notes described in the following sections:

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

The Notes do not guarantee any return of principal and you may lose all of your Principal Amount.

The Notes do not guarantee any return of principal. The Notes differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount of your Notes if the Notes are not called and the Final Value of the Least Performing Underlying is less than its Barrier Value. In this case, the Payment at Maturity you will be entitled to receive will be less than the Principal Amount and you will lose 1% for each 1% that the Reference Return of the Least Performing Underlying is less than 0.00%. You may lose up to 100% of your investment at maturity. Even with any Contingent Coupons received prior to maturity, your return on the Notes may be negative in this case.

We will not necessarily make periodic coupon payments on the Notes. If the Official Closing Price of any Underlying on an Observation Date is less than its Coupon Trigger, we will not pay you the Contingent Coupon applicable to that Observation Date. If on each of the Observation Dates, the Official Closing Price of any Underlying is less than its Coupon Trigger, we will not pay you any Contingent Coupons during the term of, and you will not receive a positive return on, the Notes. Generally, this non-payment of the Contingent Coupon coincides with a period of greater risk of principal loss on 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 any Underlying.

For each $1,000 Principal Amount, you will receive $1,000 at maturity plus the final Contingent Coupon if the Final Value of the Least Performing Underlying is equal to or greater than its Coupon Trigger, regardless of any appreciation in the value of any Underlying, which may be significant. Accordingly, the return on the Notes may be significantly less than the return on a direct investment in the Underlyings during the term of the Notes.

Since the Notes are linked to the performance of more than one Underlying, you will be fully exposed to the risk of fluctuations in the value of each Underlying.

Since the Notes are linked to the performance of more than one Underlying, the Notes will be linked to the individual performance of each Underlying. Because the Notes are not linked to a basket, in which the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the value of each Underlying. For example, in the case of notes linked to a basket, the return would depend on the aggregate performance of the basket components reflected as the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component. However, in the case of these Notes, the individual performance of each of the Underlyings would not be combined to calculate your return and the depreciation of either Underlying would not be mitigated by the appreciation of the other Underlying. Instead, your return would depend on the Least Performing Underlying.

Because the Notes are linked to the performance of the Least Performing Underlying, you are exposed to greater risks of receiving no Contingent Coupons and sustaining a significant loss on your investment than if the Notes were linked to just one Underlying.

The risk that you will not receive any Contingent Coupons, or that you will suffer a significant loss on your investment, is greater if you invest in the Notes as opposed to substantially similar securities that are linked to the performance of just one Underlying. With multiple Underlyings, it is more likely that one of the Underlyings will close below its respective Coupon Trigger on any Observation Date (including the Final Valuation Date) and below its respective Barrier Value on the Final Valuation Date, than if the Notes were linked to

only one Underlying. Therefore, it is more likely that you will not receive any Contingent Coupons, and that you will suffer a significant loss on your investment. In addition, because each Underlying must close above its Call Threshold on a Call Observation Date in order for the Notes to be called, the Notes are less likely to be called than if the Notes were linked to just one Underlying.

If the Notes are called early, the holding period over which you may receive coupon payments could be as little as approximately 3 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 called prior to the Maturity Date.

If the Notes are not called, your return will be based on the Reference Return of the Least Performing Underlying.

If the Notes are not called, your return will be based on the Reference Return of the Least Performing Underlying without regard to the performance of any other Underlying. As a result, you could lose all or some of your initial investment if the Final Value of the Least Performing Underlying is less than its Barrier Value, even if there is an increase in the value of any other Underlying. This could be the case even if any other Underlying increased by an amount greater than the decrease in the Least Performing Underlying.

Higher Contingent Coupon Rates or lower Barrier Values are generally associated with Underlyings with greater expected volatility and therefore can indicate a greater risk of loss.

"Volatility" refers to the frequency and magnitude of changes in the value of an Underlying. The greater the expected volatility with respect to an Underlying on the Pricing Date, the higher the expectation as of the Pricing Date that the value of that Underlying could close below its Coupon Trigger on an Observation Date or its Barrier Value on the Final Valuation Date, indicating a higher expected risk of non-payment of Contingent Coupons or loss on the Notes. This greater expected risk will generally be reflected in a higher Contingent Coupon Rate than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as a lower Barrier Value, a lower Coupon Trigger or a higher Contingent Coupon Rate) than for similar securities linked to the performance of an Underlying with a lower expected volatility as of the Pricing Date. You should therefore understand that a relatively higher Contingent Coupon Rate may indicate an increased risk of loss. Further, a relatively lower Barrier Value may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of an Underlying can change significantly over the term of the Notes. The value of an Underlying for your Notes could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Least Performing Underlying and the potential to lose some or all of your principal at maturity not receive any Contingent Coupons.

The amount payable on the Notes is not linked to the values of the Underlyings at any time other than the Observation Dates, including the Final Valuation Date.

The payments on the Notes will be based on the Official Closing Prices of the Underlyings on the Observation Dates, including the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the value of each Underlying is greater than or equal to its Coupon Trigger during the term of the Notes other than on an Observation Date but then decreases on an Observation Date to a value that is less than its Coupon Trigger, the Contingent Coupon will not be payable for the relevant quarterly period. Similarly, if the Notes are not called, even if the value of the Least Performing Underlying is greater than or equal to its Barrier Value during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a value that is less than its Barrier Value, the Payment at Maturity will be less, possibly significantly less, than it would have been had the Payment at Maturity been linked to the value of the Least Performing Underlying prior to such decrease. Although the actual values of the Underlyings on the Maturity Date or at other times during the term of the Notes may be higher than their respective values on the Observation Dates, whether each Contingent Coupon will be payable and the Payment at Maturity will be based solely on the Official Closing Prices of the Underlyings on the applicable Observation Dates.

Changes that affect an Underlying may affect the value of that Underlying and the market value of the Notes and the amount you will receive on the Notes and the amount you will receive at maturity.

The policies of the reference sponsor of an Underlying, concerning additions, deletions and substitutions of the stocks included in that Underlying and the manner in which the reference sponsor takes account of certain changes affecting those stocks may affect the value of that Underlying. The policies of the reference sponsor could also affect the value of that Underlying. The reference sponsor may discontinue or suspend calculation or dissemination of an Underlying. Any such actions could affect the value of an Underlying and the value of and the return on the Notes.

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.

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 payments due on the Notes.

The Estimated Initial Value of the Notes, which was determined by us on the Pricing Date, is 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 was calculated by us on the Pricing Date and is less than the price to public. The Estimated Initial Value reflects 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 pay 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 prices 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 determined 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 is expected to be less than the price to public.

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, 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 Notes, and the costs associated with structuring and hedging our obligations under the Notes. 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 values of the Underlyings 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 we 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 may initially be used for customer account statements, if any, may exceed the Estimated Initial Value on the Pricing Date for a temporary period expected to be approximately 6 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.

You will not have any ownership interest in the stocks included in an Underlying.

As a holder of the Notes, you will not have any ownership interest in the stocks included in an Underlying, such as rights to vote, dividend payments or other distributions. Because the return on the Notes will not reflect any dividends on those stocks, the Notes may underperform an investment in the stocks included in an Underlying.

The Notes will not be listed on any securities exchange or automated quotation system. HSBC Securities (USA) Inc. is not required to offer to purchase the Notes in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. 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.

An affiliate of HSBC has a minority equity interest in the owner of an electronic platform, through which we may make available certain structured investments offering materials. HSBC and its 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 the calculation agent and other affiliates of ours 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 action that might affect the value of your Notes.

For a discussion of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “U.S. Federal Income Tax Considerations” herein and the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

The following table and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the value of any Underlying relative to its Initial Value. We cannot predict the Official Closing Price of an Underlying on any Observation Date, including the Final Valuation Date. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Underlyings or the return on the Notes.

The table and examples below illustrate how the Contingent Coupon and the Payment at Maturity would be calculated with respect to a $1,000 investment in the Notes, given a range of hypothetical performances of any Underlying. The hypothetical returns on the Notes below are numbers, expressed as percentages, that result from comparing the Payment at Maturity per $1,000 Principal Amount to $1,000. You should consider carefully whether the Notes are suitable to your investment goals. The numbers appearing in the following table and examples have been rounded for ease of analysis. The following table and examples assume the following:

* The hypothetical Initial Value of $100.00 used in the examples below has been chosen for illustrative purposes only and does not represent the actual Initial Value of any Underlying. The actual Initial Value of each Underlying is set forth on page PS-3 of this document.

Example 1—The Official Closing Price of each Underlying on the second Observation Date is greater than or equal to its Call Threshold and each Underlying closed at or above its Coupon Trigger (but below its Call Threshold) on the first Observation Date prior to the Notes being called.

Because the Official Closing Price of each Underlying on the second Observation Date is at or above its Call Threshold, the Notes will be called and you will receive $1,033.70 per Note, reflecting the Principal Amount plus the Contingent Coupon. When added to the Contingent Coupon payment of $33.70 received in respect of the first Observation Date, we will have paid you a total of $1,067.40 per Note, resulting in a 6.74% return on the Notes. No extra payment will be made on account of each Underlying closing above its respective Initial Value.

Example 2— The Notes are not called, the Final Value of the Least Performing Underlying is greater than or equal to its Barrier Value, and each Underlying closed at or above its Coupon Trigger (but below its Call Threshold) on two Observation Dates prior to the Final Valuation Date.

Because the Final Value of the Least Performing Underlying is greater than or equal to its Coupon Trigger, you will receive $1,033.70 per Note, reflecting the Principal Amount plus the final Contingent Coupon.

When added to the Contingent Coupon payments of $67.40 received in respect of the previous Observation Dates, we will have paid you a total of $1,101.10 per Note, resulting in a 10.11% return on the Notes.

Example 3—The Notes are not called, the Final Value of the Least Performing Underlying is less than its Barrier Value, and the Underlyings did not all close at or above their respective Coupon Triggers on any of the Observation Dates prior to maturity.

Because the Final Value of the Least Performing Underlying is less than its Barrier Value, you will receive $400.00 per $1,000 Principal Amount, calculated as follows:

Because there was no Contingent Coupon payable in respect of the prior Observation Dates, we will pay you a total of $400.00, resulting in a -60.00% return on the Notes.

If the Notes are not called and the Final Value of the Least Performing Underlying is less than its Barrier Value, you will be exposed to any decrease in the value of the Least Performing Underlying on a 1:1 basis and could lose up to 100% of your principal at maturity.

The shares of the SPDR^® S&P^® Regional Banking ETF (the “KRE”) are issued by the SPDR^® Series Trust, a registered investment company. The KRE seeks investment results that, before fees and expenses, correspond generally to the total return performance of the S&P Regional Banks Select Industry Index. The KRE trades on the NYSE Arca under the ticker symbol “KRE”. The returns of the KRE may be affected by certain management fees and other expenses, which are detailed in its prospectus.

The KRE seeks to provide investment results that correspond generally to the total return performance, before fees and expenses, of the S&P Regional Banks Select Industry Index. Prior to October 24, 2011, the KRE’s investment strategy sought to track the total return performance, before fees and expenses, of an index different from the S&P Regional Banks Select Industry Index. Performance of the KRE prior to October 24, 2011 is therefore based on the KRE’s investment strategy with respect to the prior index, the KBW Regional Banking Index.

The KRE uses a representative sampling strategy to try to achieve its investment objective, which means that the KRE is not required to purchase all of the securities represented in the S&P Regional Banks Select Industry Index. Instead, the KRE may purchase a subset of the securities in the index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the index. Under normal market conditions, the KRE generally invests substantially all, but at least 80%, of its total assets in the securities comprising the index. The KRE will provide shareholders with at least 60 days’ notice prior to any change in this 80% investment policy. In addition, the KRE may invest in equity securities not included in the index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the KRE’s investment adviser).

In certain situations or market conditions, the KRE may temporarily depart from its normal investment policies and strategies provided that the alternative is consistent with the KRE’s investment objective and is in the best interest of the KRE. For example, the KRE may make larger than normal investments in derivatives to maintain exposure to the index if it is unable to invest directly in a component security.

The board may change the KRE’s investment strategy, index and other policies without shareholder approval. The board may also change the KRE’s investment objective without shareholder approval.

Notwithstanding the KRE’s investment objective, the return on your securities will not reflect any dividends paid on the KRE shares, on the securities purchased by the KRE or on the securities that comprise the S&P Regional Banks Select Industry Index.

The S&P Regional Banks Select Industry Index (the “SPSIRBK”) is managed by S&P Dow Jones Indices LLC (“S&P”) and is an equal-weighted index that is designed to measure the performance of stocks in the S&P Total Market Index that both (i) are classified under the Global Industry Classification Standard (“GICS^®”) in the regional banks sub-industry and (ii) satisfy certain liquidity and market capitalization requirements. The S&P Total Market Index tracks all U.S. common stocks with a primary listing on the NYSE, NYSE Arca, NYSE MKT, NASDAQ Global Select Market, NASDAQ Select Market, NASDAQ Capital Market, Bats BZX, Bats BYX, Bats EDGA or Bats EDGX exchanges. The SPSIRBK is one of the 21 sub-industry sector indices S&P maintains that are derived from a portion of the stocks comprising the S&P Total Market Index. An equal-weighted index is one where every stock has the same weight in the SPSIRBK. As such, the SPSIRBK must be rebalanced from time to time to re-establish the proper weighting.

The KRE tracks the performance of the total version of the SPSIRBK. A total return index represents the total return earned in a portfolio that tracks the price index and reinvests dividend income in the overall index, not in the specific stock paying the dividend. The difference between the price return calculation and the total return calculation is that, with respect to the price return calculation, changes in the SPSIRBK level reflect changes in stock prices, whereas with respect to the total return calculation of the SPSIRBK, changes in the SPSIRBK level reflect both movements in stock prices and the reinvestment of dividend income. Notwithstanding that the KRE tracks the performance of the total return version of the SPSIRBK, the return on your securities will not reflect any dividends paid on the KRE shares, on the securities purchased by the KRE or on the securities that comprise the SPSIRBK.

The price return index is calculated as the SPSIRBK market value divided by the divisor. The total return calculation begins with the price return of the SPSIRBK. Given the SPSIRBK is an equal-weighted index, the market capitalization of each stock used in the calculation of the SPSIRBK market value is redefined so that each stock has an equal weight in the SPSIRBK on each rebalancing date. The adjusted market capitalization for each stock in the SPSIRBK is calculated as the product of the stock price, the number of shares outstanding, the stock’s float factor and the adjustment factor.

A stock’s float factor refers to the number of shares outstanding that are available to investors. S&P indices exclude shares closely held by control groups from the SPSIRBK calculation because such shares are not available to investors. For each stock, S&P calculates an Investable Weight Factor (IWF) which is the percentage of total shares outstanding that are included in the SPSIRBK calculation.

The adjustment factor for each stock is assigned at each rebalancing date and is calculated by dividing a specific constant set for the purpose of deriving the adjustment factor (often referred to as modified index shares) by the number of stocks in the SPSIRBK multiplied by the float adjusted market value of such stock on such rebalancing date.

Adjustments are also made to ensure that no stock in the SPSIRBK will have a weight that exceeds the value that can be traded in a single day for a theoretical portfolio of $2 billion. Theoretical portfolio values are reviewed annually and any updates are made at the discretion of the index committee, as defined below.

The maximum basket liquidity weight for each stock in the SPSIRBK will be calculated using the ratio of its three-month median daily value traded to the theoretical portfolio value of $2 billion. Each stock’s weight in the SPSIRBK is then compared to its maximum basket liquidity weight and is set to the lesser of (1) its maximum basket liquidity weight or (2) its initial equal weight. All excess weight is redistributed across the SPSIRBK to the uncapped stocks. If necessary, a final adjustment is made to ensure that no stock in the SPSIRBK has a weight greater than 4.5%. No further adjustments are made if the latter step would force the weight of those stocks limited to their maximum basket liquidity weight to exceed that weight. If the SPSIRBK contains exactly 22 stocks as of the rebalancing effective date, the SPSIRBK will be equally weighted without basket liquidity constraints.

If a company has more than one share class line in the S&P Total Market Index, such company will be represented once by the primary listing (generally the most liquid share line). In the event that a company issues a secondary share class to the index share class holders by means of a mandatory distribution, the newly issued share class line will be added to the SPSIRBK on the distribution ex-date, provided that the distributed class is not considered to be de minimis. Both share class lines will then remain in the SPSIRBK until the next rebalancing, at which time only the primary share class line will be considered for continued inclusion.

The index is calculated by using the divisor methodology used in all S&P equity indices. The initial divisor was set to have a base value of 1,000 on June 20, 2003. The index level is the index market value divided by the index divisor. In order to maintain index series continuity, it is also necessary to adjust the divisor at each rebalancing. Therefore, the divisor (after rebalancing) equals the index market value (after rebalancing) divided by the index value before rebalancing. The divisor keeps the SPSIRBK comparable over time and is one manipulation point for adjustments to the SPSIRBK, which we refer to as maintenance of the SPSIRBK.

Once the price return index has been calculated, the total return index is calculated. First, the total daily dividend for each stock in the SPSIRBK is calculated by multiplying the per share dividend by the number of shares included in the SPSIRBK. Then the index dividend is calculated by aggregating the total daily dividends for each of the SPSIRBK stocks (which may be zero for some stocks) and dividing by the divisor for that day. Next the daily total return of the SPSIRBK is calculated as a fraction minus 1, the numerator of which is the sum of the index level plus the index dividend and the denominator of which is the index level on the previous day. Finally, the total return index for that day is calculated as the product of the value of the total return index on the previous day times the sum of 1 plus the index daily total return for that day.

The composition of the SPSIRBK is reviewed quarterly. Rebalancing occurs after the closing of the relevant U.S. trading markets on the third Friday of the month ending that quarter. The reference date for float-adjusted market capitalization and the float-adjusted liquidity ratio is after the closing of the last trading day of the previous month. The reference date for GICS^® classification is as of the rebalancing effective date. Existing stocks in the SPSIRBK are removed at the quarterly rebalancing if either their float-adjusted capitalization falls below $1 billion or their float-adjusted liquidity ratio falls below 50%. A company will also be deleted from the SPSIRBK if the S&P Total Market Index deletes that company. Companies are added between rebalancings only if a company deletion causes the number of companies in the SPSIRBK to fall below 22. The newly added company will be added to the SPSIRBK at the weight of the deleted company. If the stock was deleted at $0.00, the newly added stock will be added at the deleted stock’s previous day’s closing value (or the most immediate prior business day that the deleted stock was not valued at $0.00) and an adjustment to the divisor will be made (only in the case of stocks removed at $0.00). At the next rebalancing, the SPSIRBK will be rebalanced based on the eligibility requirements and equal-weight methodology discussed above. In the case of GICS^® changes, where a stock no longer qualifies to belong to the SPSIRBK after the classification change, it is removed from the SPSIRBK on the next rebalancing date. In the case of a spin-off, the spin-off company will be added to the SPSIRBK at a zero price after the close of the trading on the day before the ex-date. In general and subject to certain exceptions, both the parent company and spin-off companies will remain in the SPSIRBK until the next index rebalancing.

In the case of mergers involving two index constituents, the merged entity will remain in the SPSIRBK provided that it meets all general eligibility requirements. The merged entity will be added to the SPSIRBK at the weight of the stock deemed to be the surviving stock in the transaction. The surviving stock will not experience a weight change and its subsequent weight will not be equal to that of the pre-merger weight of the merged entities.

The XBI is an investment portfolio maintained and managed by SSgA Funds Management, Inc. The inception date of the XBI is January 31, 2006. The XBI is an exchange traded fund that trades on NYSE Arca under the ticker symbol “XBI.” The XBI seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P^® Biotechnology Select Industry^®Index (the “underlying index”). The underlying index represents the biotechnology sub-industry portion of the S&P Total Market Index (“S&P TMI”), an index that measures the performance of the U.S. equity market. The XBI is composed of companies that are in the biotechnology sector. The returns of the XBI may be affected by certain management fees and other expenses, which are detailed in its prospectus. The XBI utilizes a “replication” investment approach in attempting to track the performance of its underlying index. The XBI typically invests in substantially all of the securities which comprise the underlying index in approximately the same proportions as the underlying index. The XBI will normally invest at least 80% of its total assets in the common stocks that comprise the underlying index. Information provided to or filed with the SEC by the Select Sector SPDR^® Trust pursuant to the Securities Act of 1933 and the Investment Company Act of 1940 can be located by reference to SEC file numbers 333-57791 and 811-08837, respectively, through the SEC’s website at http://www.sec.gov.

The underlying index is an equal-weighted index that is designed to measure the performance of the biotechnology sub-industry portion of the S&P TMI. The S&P TMI includes all U.S. common equities listed on the NYSE (including NYSE Arca), the NYSE MKT, the NASDAQ Global Select Market, and the NASDAQ Capital Market. Each of the component stocks in the underlying index is a constituent company within the biotechnology sub-industry portion of the S&P TMI. To be eligible for inclusion in the underlying index, companies must be in the S&P TMI and must be included in the relevant Global Industry Classification Standard (GICS) sub-industry. The GICS was developed to establish a global standard for categorizing companies into sectors and industries. In addition to the above, companies must satisfy one of the two following combined size and liquidity criteria: (i) float-adjusted market capitalization above US$500 million and float-adjusted liquidity ratio above 90%; or (ii) float-adjusted market capitalization above US$400 million and float-adjusted liquidity ratio above 150%. All U.S. companies satisfying these requirements are included in the underlying index. The total number of companies in the underlying index should be at least 35. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds above are included in order of their float-adjusted market capitalization to reach 35 constituents. Minimum market capitalization requirements may be relaxed to ensure there are at least 22 companies in the underlying index as of each rebalancing effective date.

Eligibility factors include: (i) Market Capitalization: Float-adjusted market capitalization should be at least US$400 million for inclusion in the underlying index. Existing index components must have a float-adjusted market capitalization of US$300 million to remain in the underlying index at each rebalancing. (ii) Liquidity: The liquidity measurement used is a liquidity ratio, defined as dollar value traded over the previous 12-months divided by the float-adjusted market capitalization as of the underlying index rebalancing reference date. Stocks having a float-adjusted market capitalization above US$500 million must have a liquidity ratio greater than 90% to be eligible for addition to the underlying index. Stocks having a float-adjusted market capitalization between US$400 and US$500 million must have a liquidity ratio greater than 150% to be eligible for addition to the underlying index. Existing index constituents must have a liquidity ratio greater than 50% to remain in the underlying index at the quarterly rebalancing. The length of time to evaluate liquidity is reduced to the available trading period for IPOs or spin-offs that do not have 12 months of trading history. (iii) Takeover Restrictions: At the discretion of S&P, constituents with shareholder ownership restrictions defined in company bylaws may be deemed ineligible for inclusion in the underlying index. Ownership restrictions preventing entities from replicating the index weight of a company may be excluded from the eligible universe or removed from the underlying index. (iv) Turnover: S&P believes turnover in index membership should be avoided when possible. At times, a company may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the underlying index, not for continued membership. As a result, an index constituent that appears to violate the criteria for addition to the underlying index will not be deleted unless ongoing conditions warrant a change in the composition of the underlying index.

The Select Sector SPDR^® Trust is a registered investment company that consists of eleven separate investment portfolios (each, a “Select Sector SPDR^® Fund”), including the XLK. Each Select Sector SPDR^® Fund is an Index Fund that invests in a particular sector or group of industries represented by a specified Select Sector Index (together, the “Select Sector Indices”). The companies included in each Select Sector Index are selected on the basis of the Global Industry Classification Standard from a universe of companies defined by the S&P 500^® Index (the “SPX”). The Select Sector Indices upon which the Select Sector SPDR^® Funds are based, together, comprise all of the companies in the SPX. Additional information about how each of the Select Sector Indices is determined and calculated can be found in the section “The Financial Select Sector SPDR^® Fund” beginning on page S-12 of the ETF Underlying Supplement, and is applicable to the XLK, except as discussed in this section.

Information provided to or filed with the SEC by the Select Sector SPDR^® Trust pursuant to the Securities Act, and the Investment Company Act, can be located by reference to SEC file numbers 333-57791 and 811-08837, respectively, through the SEC’s website at http://www.sec.gov.

The Technology Select Sector SPDR^® Fund trades on the NYSE under the ticker symbol “XLK.”

The XLK seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the Technology Select Sector Index. The Technology Select Sector Index measures the performance of the technology sector of the U.S. equity market. The Technology Select Sector Index is composed of companies whose primary line of business is directly associated with the technology sector. The returns of the XLK may be affected by certain management fees and other expenses, which are detailed in its prospectus.

The Technology Select Sector Index includes companies from the following industries: computers & peripherals; software; diversified telecommunication services; communications equipment; semiconductors & semiconductor equipment; internet software & services; IT services; electronic equipment, instruments & components; wireless telecommunication services; and office electronics. As of January 31, 2020, the Technology Select Sector Index is one of eleven Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the index is a constituent company of the S&P 500^® Index; and (2) the index is calculated by SPDJI based on methodology proprietary to the SPDJI and BofA Merrill Lynch Research using a “modified market capitalization” methodology, which means that modifications may be made to the market capitalization weights of single stock concentrations in order to conform to the requirements of the Internal Revenue Code of 1986, as amended.

The following graph sets forth the historical performance of the XLK based on the daily historical closing values from November 13, 2010 through November 13, 2020. We obtained the closing values below from 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 values of the XLK should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Value of the XLK on any Observation Date, including the Final Valuation Date.

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 due and payable in the same general manner as described in this document except that in such a case, the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the Reference Return of an Underlying, and the accelerated Maturity Date will be three business days after the accelerated Final Valuation Date. If a Market Disruption Event exists with respect to an Underlying on that scheduled trading day, then the accelerated Final Valuation Date for that Underlying will be postponed for up to five scheduled trading days (in the same 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 following the postponed accelerated Final Valuation Date. For the avoidance of doubt, if no Market Disruption Event exists with respect to an Underlying on the scheduled trading day preceding the date of acceleration, the determination of such Underlying’s Final Value will be made on such date, irrespective of the existence of a Market Disruption Event with respect to any other Underlying occurring on such 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.

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the Notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the Notes from HSBC at the price to public less the underwriting discount set forth on the cover page of this document, for distribution to other registered broker-dealers, or will offer the Notes directly to investors. HSBC Securities (USA) Inc. has offered the Notes at the price to public set forth on the cover page of this document. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 1.75% per $1,000 Principal Amount in connection with the distribution of the Notes to other registered broker-dealers.

An affiliate of HSBC has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the Notes.

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

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-61 in the prospectus supplement.

Delivery of the Notes will be made against payment for the Notes on the Original Issue Date set forth on the inside cover page of this document, which is more than two business days following the Trade Date. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to that 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 an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

There is no direct legal authority as to the proper tax treatment of the Notes, and therefore significant aspects of the tax treatment of the Notes are uncertain as to both the timing and character of any inclusion in income in respect of the Notes. Under one approach, a Note should be treated as a contingent income-bearing pre-paid executory contract with respect to the Underlyings. We intend to treat the Notes consistent with this approach. 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 the limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Mayer Brown LLP, it is reasonable to treat a Note as a contingent income-bearing pre-paid executory contract with respect to the Underlyings. 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 herein. 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.

We will not attempt to ascertain whether the Underlyings or any of the entities whose stock is owned by the Underlyings 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 the Underlyings or one or more of the entities whose stock is owned by the Underlyings 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 Underlyings and the entities whose stock is owned by the Underlyings and consult your tax advisor regarding the possible consequences to you if an Underlying or one or more of the entities whose stock is owned by the Underlyings is or becomes a PFIC or a USRPHC.

U.S. Holders. Please see the discussion under the heading “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 further discussion of U.S. federal income tax considerations applicable to U.S. holders (as defined in the accompanying prospectus supplement). Pursuant to the approach discussed above, 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, 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.

Non-U.S. Holders. Please see the discussion under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of Non-U.S. Holders” in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to non-U.S. holders (as defined in the accompanying prospectus supplement). Because the U.S. federal income tax treatment (including the applicability of withholding) of the Contingent Coupons is uncertain, 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.

Under current law, while the matter is not entirely clear, individual non-U.S. holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, the Notes are likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in the Notes.

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 the Issuer’s 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 Underlyings 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 the Underlyings 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.

For a discussion of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

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