The Notes

These Barrier Participation Notes with Call Feature may be suitable for investors who believe that the Underlyings will increase over the term of the Notes. So long as the Reference Return of the Least Performing Underlying is greater than -50.00%, the Notes will outperform the Reference Return of Least Performing Underlying.

If the Official Closing Price of each Underlying is at or above its Call Threshold on the Call Observation Date, your Notes will be automatically called and you will receive a payment equal to 100% of the Principal Amount, together with the Call Premium on the Call Payment Date.

If the Notes are not called, and if at maturity:

(i)       the Least Performing Underlying appreciates over the term of the Notes, you will realize a return equal to 200.00% (2.00x) of the appreciation of the Least Performing Underlying;

(ii)      the Reference Return of the Least Performing Underlying is less than or equal to zero but greater than or equal to the Barrier Percentage of -50.00%, you will receive a Payment at Maturity equal to 100% of the Principal Amount; or

(iii)     the Reference Return of the Least Performing Underlying is less than the Barrier Percentage, you will receive the Physical Delivery Amount and lose 1% of your investment for every 1% decline in the Least Performing Underlying from its Initial Value, and you may lose up to 100% of your Principal Amount at maturity.

PAYMENT ON THE NOTES

Call Feature

If the Official Closing Price of each Underlying is at or above its Call Threshold on the 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 Call Premium on the Call Payment Date.

Call Premium

If the Notes are called on the Call Observation Date, we will pay the Call Premium on the Call Payment Date, which will be at least 40.00% (or $400.00 for each $1,000 Principal Amount) (to be determined on the Trade Date). For information regarding the record dates applicable to the Call Premiums payable on the Notes, please see the section entitled “Description of Notes—Interest and Principal Payments—Recipients of Interest Payments” beginning on page S-17 in the accompanying prospectus supplement.

Payment at Maturity

Unless the Notes are called, on the Maturity Date, for each Note you hold, we will pay you the Final Settlement Value, which is an amount in cash, as described below:

If the Reference Return of the Least Performing Underlying is greater than or equal to zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Reference Return of the Least Performing Underlying × Upside Participation Rate).

If the Reference Return of the Least Performing Underlying is less than zero but greater than or equal to the Barrier Percentage, you will receive:

$1,000 per $1,000 Principal Amount (zero return).

If the Reference Return of the Least Performing Underlying is less than the Barrier Percentage, you will receive the Physical Delivery Amount in shares of the Least Performing Underlying.

Under these circumstances, you will lose 1% of the Principal Amount of your Notes for each percentage point that the Reference Return of the Least Performing Underlying is less than zero. For example, if the Reference Return of the Least Performing Underlying is
-60.00%, you will suffer a 60.00% loss and receive shares of the Least Performing Underlying with a value equal to 40.00% of the Principal Amount, subject to the credit risk of HSBC. If the Reference Return of the Least Performing Underlying is less than the Barrier Percentage, you will lose some or all of your investment.

Interest

The Notes will not pay interest.

Calculation Agent

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

FWP-7

INVESTOR SUITABILITY

The Notes may be suitable for you if:

► You seek (i) a Call Premium based on the performance of the Underlyings, that will be payable if the Official Closing Price of each Underlying is greater than or equal to the Call Threshold on the Call Observation Date; and /or (ii) an investment with an enhanced return linked to the potential positive performance of the Least Performing Underlying and you believe the Reference Return of the Least Performing Underlying will be positive or will not decline below the Barrier Percentage of -50.00%.

► You are willing to make an investment that is exposed to the negative Reference Return of the Least Performing Underlying on a 1-to-1 basis from the Initial Value, and receive shares of the Least Performing Underlying, if the Reference Return of the Least Performing Underlying is less than the Barrier Percentage.

► You understand and accept that your investment may not provide full return of principal.

► 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 willing to forgo dividends or other distributions paid to holders of the stocks included in any Underlying.

► You do not seek current income from your investment.

► You do not seek an investment for which there is an active secondary market.

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

The Notes may not be suitable for you if:

► You are unwilling to make an investment that is exposed to the negative Reference Return of the Least Performing Underlying on a 1-to-1 basis from the Initial Value, and receive shares of the Least Performing Underlying if the Reference Return of the Least Performing Underlying is less than the Barrier Percentage.

► You seek an investment that provides full return of principal.

► 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.

FWP-8

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and on page S-1 of the accompanying Stock-Linked 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 Stock-Linked Underlying Supplement.

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

4 “— Risks Relating to All Note Issuances” in the prospectus supplement; and

4 “— General Risks Related to Indices” in the Stock-Linked Underlying Supplement.

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

Risks Relating to the Structure or Features of the Notes

Your investment in the Notes may result in a loss.

You will be exposed to the decline in the Final Value from the Initial Value if the Reference Return of the Least Performing Underlying is beyond the Barrier Percentage of -50.00%. In this case, we will pay you in shares of the Least Performing Underlying, and the Physical Delivery Amount 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%. Accordingly, if the Reference Return of the Least Performing Underlying is less than the Barrier Percentage of -50.00%, your Payment at Maturity will be less than the Principal Amount of your Notes. You will lose some or all of your investment at maturity if the Reference Return of the Least Performing Underlying is less than the Barrier Percentage.

If the Physical Delivery Amount will be paid on the Notes, you will be subject to the price fluctuation of the Least Performing Underlying after the Final Valuation Date.

If the Reference Return of the Least Performing Underlying is beyond the Barrier Percentage, we will deliver to you at maturity the Physical Delivery Amount in shares of the Least Performing Underlying. The value of those shares may further decrease between the Final Valuation Date and the Maturity Date, and you will incur additional losses to the extent of such decrease. In addition, there is no assurance that an active trading market will continue for shares of the Least Performing Underlying or that there will be liquidity in that trading market.

You may not receive the Call Premium.

The Notes may not be called, and in such a case you will not receive the Call Premium.

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

The payments on the Notes will be based on the Official Closing Prices of the Underlyings on the Call Observation Date and, if the Notes are not called, 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 Call Threshold during the term of the Notes other than on the Call Observation Date but then decreases on the Call Observation Date to a value that is less than its Call Threshold, the Call Premium will not be payable for the relevant Call Payment Date. Similarly, if the Notes are not called, even if the value of the Least Performing Underlying appreciates 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 reflects a Reference Return that is less than the Barrier Percentage, the Payment at Maturity may be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the 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 Call Observation Date or the Final Valuation Date, the Call Premium will be based solely on the Official Closing Prices of the Underlyings on the Call Observation Date, and the Payment at Maturity will be based solely on the Official Closing Price of the Least Performing Underlying on the Final Valuation Date.

The Notes will not bear interest.

As a holder of the Notes, you will not receive interest payments.

FWP-9

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 sustaining a significant loss on your investment than if the Notes were linked to just one Underlying. 

The risk 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 the Reference Return of one of the Underlyings will be below the Barrier Percentage on the Final Valuation Date, than if the Notes were linked to only one Underlying. Therefore, it is more likely that you will suffer a significant loss on your investment.

Risks Relating to the Reference Asset

Risks Associated with the Energy Sector

Each of the Underlyings develop and produce crude oil and natural gas and provide drilling and other energy resources production and distribution related services. Consequently, the value of the Notes may be subject to greater volatility and be more adversely affected by a single economic, environmental, political or regulatory occurrence affecting such industries than an investment linked to a more broadly diversified group of issuers. Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for energy products and services in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. The stock prices of oil service companies could be subject to wide fluctuations in response to a variety of factors, including the ability of the OPEC to set and maintain production levels and pricing, the level of production in non-OPEC countries, the demand for oil and gas, which is negatively impacted by economic downturns, the policies of various governments regarding exploration and development of oil and gas reserves, advances in exploration and development technology and the political environment of oil-producing regions. Correspondingly, securities of companies in the energy field are subject to swift price and supply fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies. Weak demand for the companies’ products or services or for energy products and services in general, as well as negative developments in these other areas, would adversely impact the performance of each of the Underlyings.

General Risk Factors

The Notes are subject to the credit risk of HSBC USA Inc.

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

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.

FWP-10

The Estimated Initial Value of the Notes, which will be determined by us on the Trade Date, is expected to be less than the price to public and may differ from the market value of the Notes in the secondary market, if any.

The Estimated Initial Value of the Notes will be calculated by us on the Trade Date and is expected to be less than the price to public. The Estimated Initial Value will reflect our internal funding rate, which is the borrowing rate we pay to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the Notes may be lower if it were based on the 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 will determine the value of the embedded derivatives in the Notes by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the Notes that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your Notes in the secondary market (if any exists) at any time.

The price of your Notes in the secondary market, if any, immediately after the Trade 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 Trade 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 any Underlying.

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

The Notes lack liquidity.

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.

FWP-11

Potential conflicts of interest may exist.

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.

Uncertain tax treatment.

ILLUSTRATIVE EXAMPLES

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 Final Value of an Underlying. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events, and the hypothetical Initial Value used in the table and examples below is not expected to be the actual Initial Value of any Underlying. 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 your Notes. The Final Settlement Value may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including such a security issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Payment at Maturity if the Notes are not called on a $1,000 investment in the Notes for a hypothetical range of Reference Returns of the Least Performing Underlying from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Notes” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount to $1,000. The potential returns described here assume that your Notes are held to maturity. You should consider carefully whether the Notes are suitable to your investment goals. The following table and examples assume the following:

4	Principal Amount:	$1,000
4	Hypothetical Initial Value for each Underlying:	$100.00
4	Call Threshold	110.00%
4	Hypothetical Call Premium*	40.00%
4	Maximum Cap	None
4	Upside Participation Rate:	200.00%
4	Barrier Percentage:	-50.00%

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 will be determined on the Pricing Date.

*To be determined on the Trade Date and will be at least 40.00%.

Hypothetical Final Value of the Least Performing Underlying	Hypothetical Reference Return of the Least Performing Underlying	Hypothetical Payment at Maturity	Hypothetical Return on the Notes
$200.00	100.00%	$3,000.00	200.00%

The following examples indicate how the Final Settlement Value would be calculated with respect to a hypothetical $1,000 investment in the Notes.

Example 1: The Official Closing Price of each Underlying on the Call Observation Date is greater than or equal to its Call Threshold.

Underlying	Initial Value	Official Closing Price
CVX	$100.00	$125.00 (130.00% of Initial Value)
MPC	$100.00	$120.00 (120.00% of Initial Value)
VLO	$100.00	$195.00 (196.00% of Initial Value)

Payment Upon a Call: $1,400.00

Because the Official Closing Price of each Underlying on the Call Observation Date is at or above its Call Threshold, the Notes will be called and you will receive $1,400.00 per Note, reflecting the Principal Amount plus the hypothetical Call Premium, resulting in a 40.00% 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 and the value of the Least Performing Underlying increases from the Initial Value of $100.00 to a Final Value of $105.00.

Underlying	Initial Value	Final Value
CVX	$100.00	$125.00 (125.00% of Initial Value)
MPC	$100.00	$105.00 (105.00% of Initial Value)
VLO	$100.00	$110.00 (110.00% of Initial Value)

MPC is the Least Performing Underlying.

Reference Return of the Least Performing Underlying:	5.00%
Final Settlement Value:	$1,100.00

Because the Reference Return of the Least Performing Underlying is positive, the Final Settlement Value would be $1,100.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Reference Return of the Least Performing Underlying × Upside Participation Rate)

= $1,000 + ($1,000 × 5.00% × 200.00%)

= $1,100.00

Example 2 shows that you will receive the return of your principal investment plus a return equal to the Reference Return of the Least Performing Underlying multiplied by the Upside Participation Rate of 200.00% when the Reference Return of the Least Performing Underlying is positive.

FWP-14

Example 3: The Notes are not called and the value of the Least Performing Underlying decreases from the Initial Value of $100.00 to a Final Value of $95.00.

Underlying	Initial Value	Final Value
CVX	$100.00	$115.00 (115.00% of Initial Value)
MPC	$100.00	$95.00 (95.00% of Initial Value)
VLO	$100.00	$105.00 (105.00% of Initial Value)

MPC is the Least Performing Underlying.

Reference Return of the Least Performing Underlying:	-5.00%
Final Settlement Value:	$1,000.00

Because the Reference Return of the Least Performing Underlying is less than zero but greater than the Barrier Percentage of -50.00%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 4: The Notes are not called and the value of the Least Performing Underlying decreases from the Initial Value of $100.00 to a Final Value of $40.00.

Underlying	Initial Value	Final Value
CVX	$100.00	$110.00 (110.00% of Initial Value)
MPC	$100.00	$40.00 (40.00% of Initial Value)
VLO	$100.00	$105.00 (105.00% of Initial Value)

MPC is the Least Performing Underlying.

Reference Return of the Least Performing Underlying:	-60.00%
Final Settlement Value:	$400.00

Because the Reference Return of the Least Performing Underlying is less than the Barrier Percentage, you will receive the Physical Delivery Amount, calculated as follows:

Physical Delivery Amount = Principal Amount/Initial Value of the Least Performing Underlying.

= $1,000/$100.00 = 10 shares of the Least Performing Underlying

As of the Valuation Date, these shares would have a value of $400.00 (10 shares multiplied by the Final Value of the Least Performing Underlying of $40.00). The value of the Physical Delivery Amount would result in a -60.00% return on the Notes.

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the value of the Least Performing Underlying if its Reference Return is beyond the Barrier Percentage of -50.00%. You may lose some or all of your investment.

EVENTS OF DEFAULT AND ACCELERATION

If the Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Notes, the calculation agent will determine the accelerated payment 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 the Reference Asset, 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 the Reference Asset on that scheduled trading day, then the accelerated Final Valuation Date for the Reference Asset 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. 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 Reference Return 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.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

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 the pricing supplement to which this document relates, for distribution to other registered broker-dealers, or will offer the Notes directly to investors. HSBC Securities (USA) Inc. proposes to offer 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 0.25% 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 the pricing supplement to which this document relates 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-83 in the prospectus supplement.

We expect that delivery of the Notes will be made against payment for the Notes on or about 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.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

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 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 pre-paid executory contract with respect to the Underlyings. Pursuant to this approach, we do not intend to report any income or gain with respect to the Notes prior to their maturity or an earlier sale, call or exchange and we intend to treat any gain or loss upon maturity or an earlier sale, call or exchange as long-term capital gain or loss, provided you have held the Note for more than one year at such time for U.S. federal income tax purposes. If the Notes are held by the same United States holder until maturity, that holder’s holding period will generally include the maturity date. If upon maturity of the Notes, you receive shares of the Least Performing Underlying (the “Underlying Shares”) and cash in lieu of any fractional Underlying Share, you should generally recognize capital gain or loss equal to the difference between the amount of cash received in lieu of any fractional Underlying Share and the pro rata portion of your tax basis in the Notes that is allocable to such fractional Underlying Share, based on the amount of cash received and the fair market value of the Underlying Shares received. Although no assurances can be provided in this regard, you may generally expect not to recognize any gain or loss with respect to any Underlying Shares received. You

FWP-18 

should generally have a basis in the Underlying Shares equal to your tax basis in the Notes, other than any amount allocated to a fractional Underlying Share. The holding period for such Underlying Shares should start on the day after receipt.

We will not attempt to ascertain whether any Underlying 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 any Underlying 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 consult your tax advisor regarding the possible consequences to you if any Underlying is or becomes a PFIC or a USRPHC.

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 an Underlying 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 an Underlying 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.
