Selected Purchase Considerations

· AUTOMATIC CALL FEATURE — The Notes will be automatically called if the Official Closing Level on any Observation Date is at or above the Initial Level. If the Notes are automatically called, you will receive, on the applicable Call Payment Date, a cash payment per $1,000 Principal Amount of Notes equal to the Principal Amount plus the Call Premium. The Call Premiums are 12.50% of the Principal Amount if called on the first Observation Date, 25.00% if called on the second Observation Date and 37.50% if called on the Final Observation Date.

· DIVERSIFICATION OF THE EURO STOXX 50^® INDEX — The return on the Notes is linked to the EURO STOXX 50^® Index. The EURO STOXX 50^® Index consists of 50 component stocks from the Eurozone. For additional information about the Reference Asset, see the information set forth under “The EURO STOXX 50^® Index” in the Equity Index Underlying Supplement.

Investor Suitability

The Notes may be suitable for you if:   §     You believe that the Official Closing Level of the Reference Asset will be greater than or equal to the Initial Level on at least one of the Observation Dates.   §     You are willing to make an investment that is exposed to downside performance of the Reference Asset on a 1-to-1 basis if the Final Level is less than the Trigger Level.   §     You are willing to hold the Notes that will be automatically called on any of the Observation Dates on which the Official Closing Level of the Reference Asset is at or above the Initial Level.   §     You are willing to invest in the Notes based on the fact that your maximum potential return is any Call Premium payable on the Notes.   §     You are willing to forgo dividends or other distributions paid on the stocks included in the Reference Asset.   §     You are willing to hold the Notes to maturity.   §     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 Level of the Reference Asset will be less than the Initial Level on each Observation Date.   §     You are unwilling to make an investment that is exposed to downside performance of the Reference Asset on a 1-to-1 basis if the Final Level is less than the Trigger Level.   §     You are unable or unwilling to hold the Notes that will be automatically called on any of the Observation Dates on which the Official Closing Level of the Reference Asset is at or above the Initial Level, or you are otherwise unable or unwilling to hold the Notes to maturity.   §     You are unwilling to invest in the Notes based on the fact that your maximum potential return is any Call Premium payable on the Notes.   §     You prefer to receive dividends or other distributions paid on the stocks included in the Reference Asset.   §     You prefer an investment that provides upside participation in the Reference Asset, as opposed to any Call Premium payable on the Notes.   §     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.

Selected Risk Considerations

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

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

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

· REINVESTMENT RISK — If your Notes are automatically called, the term of the Notes may be as short as approximately 12 months. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are automatically called prior to the maturity date. No portion of the fees and commissions described on the cover page will be repaid if the Notes are automatically called.

· YOUR RETURN ON THE NOTES IS LIMITED TO THE PRINCIPAL AMOUNT PLUS THE CALL PREMIUM, IF ANY, REGARDLESS OF ANY APPRECIATION IN THE LEVEL OF THE REFERENCE ASSET — If the level of the Reference Asset is greater than or equal to the Initial Level on any Observation Date, the Notes will be called and you will receive the Principal Amount plus the applicable Call Premium, regardless of any appreciation in the level of the Reference Asset, which may be significant. Accordingly, the return on the Notes may be significantly less than the return on a direct investment in the Reference Asset during the term of the Notes.

· THE AMOUNT PAYABLE ON THE NOTES IS NOT LINKED TO THE LEVEL OF THE REFERENCE ASSET AT ANY TIME OTHER THAN ON THE OBSERVATION DATES AND THE FINAL VALUATION DATE — The Final Level will be based on the Official Closing Level of the Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain market disruption events. Even if the level of the Reference Asset appreciates during the term of the Notes other than on the Final Valuation Date but then drops on the Final Valuation Date to a level that is less than the Trigger Level, 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 level of the Reference Asset prior to such decrease. Although the actual level of the Reference Asset on the Maturity Date or at other times during the term of the Notes may be higher than the Final Level, the Payment at Maturity will be based solely on the Official Closing Level of the Reference Asset on the Final Valuation Date. Similarly, whether the Call Premium with respect to an Observation Date is paid will depend on the Official Closing Level of the Reference Asset on that day.

· 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.

· HIGHER CALL PREMIUMS OR LOWER TRIGGER LEVELS ARE GENERALLY ASSOCIATED WITH REFERENCE ASSETS WITH GREATER EXPECTED VOLATILITY AND THEREFORE CAN INDICATE A GREATER RISK OF LOSS — "Volatility" refers to the frequency and magnitude of changes in the level of the Reference Asset. The greater the expected volatility with respect to the Reference Asset on the Pricing Date, the higher the expectation as of the Pricing Date that the level of the Reference Asset could close below its Trigger Level on the Final Valuation Date, indicating a higher expected risk of loss on the Notes. This greater expected risk will generally be reflected in a higher call premium payment than the yield payable on our conventional debt securities with a similar maturity, or in more favorable terms (such as a lower Trigger Level or a higher Call Premium) than for similar securities linked to the performance of the Reference Asset with a lower expected volatility as of the Pricing Date. You should therefore understand that a relatively higher Call Premium may indicate an increased risk of loss. Further, a relatively lower Trigger Level may not necessarily indicate that the Notes have a greater likelihood of a repayment of principal at maturity. The volatility of the Reference Asset can change significantly over the term of the

-4-

Notes. The level of the Reference Asset could fall sharply, which could result in a significant loss of principal. You should be willing to accept the downside market risk of the Reference Asset and the potential to lose some or all of your principal at maturity.

· THE ESTIMATED INITIAL VALUE OF THE NOTES, WHICH WILL BE DETERMINED BY US ON THE PRICING DATE, WILL BE LESS THAN THE PRICE TO PUBLIC AND MAY DIFFER FROM THE MARKET VALUE OF THE NOTES IN THE SECONDARY MARKET, IF ANY — The Estimated Initial Value of the Notes will be calculated by us on the Pricing Date and will be less than the price to public. The Estimated Initial Value will reflect our internal funding rate, which is the borrowing rate we pay to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the Notes may be lower if it were based on the 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 PRICING DATE WILL BE LESS THAN THE PRICE TO PUBLIC — The price to public takes into account certain costs. These costs will include our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes, the underwriting discount and the costs associated with structuring and hedging our obligations under the Notes. These costs, except for the underwriting discount, will be used or retained by us or one of our affiliates. If you were to sell your Notes in the secondary market, if any, the price you would receive for your Notes may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Reference Asset and changes in market conditions, and cannot be predicted with accuracy. The Notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Notes to maturity. Any sale of the Notes prior to maturity could result in a loss to you.

· IF HSBC SECURITIES (USA) INC. WERE TO REPURCHASE YOUR NOTES IMMEDIATELY AFTER THE ORIGINAL ISSUE DATE, THE PRICE YOU RECEIVE MAY BE HIGHER THAN THE ESTIMATED INITIAL VALUE OF THE NOTES — Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed the Estimated Initial Value on the Pricing Date for a temporary period expected to be approximately 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.

· NO INTEREST OR DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the Notes, you will not receive interest payments, and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of securities included in the Reference Asset would have. An investment in the Notes may return less than a hypothetical investment in the securities included in the Reference Asset.

· RISKS ASSOCIATED WITH NON-U.S. COMPANIES — The level of the Reference Asset depends upon the stocks of non-U.S. companies, and thus involve risks associated with the home countries of those non-U.S. companies. The prices of these non-U.S. stocks may be affected by political, economic, financial and social factors in the home country of each applicable company, including changes in that country’s government, economic and fiscal policies, currency exchange laws or other laws or restrictions, which could affect the value of the Notes. These foreign securities may have less liquidity and could be more volatile than many of the securities traded in U.S. or other securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may affect trading levels or prices and volumes in those markets.

-5-

The other special risks associated with foreign securities may include, but are not limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; different accounting and disclosure standards; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of the Reference Asset and, as a result, the value of the Notes.

· THE NOTES WILL NOT BE ADJUSTED FOR CHANGES IN EXCHANGE RATES — Although the equity securities that comprise the Reference Asset are traded in euro, and your Notes are denominated in U.S. dollars, the amount payable on your Notes at maturity, if any, will not be adjusted for changes in the exchange rates between the U.S. dollar and the euro. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the level of the Reference Asset, and therefore your Notes. The amount we pay in respect of your Notes on the maturity date, if any, will be determined solely in accordance with the procedures described in this free writing prospectus.

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

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

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

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

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

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

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

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

-6-

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

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

· the actual and expected volatility of the Reference Asset;

· the time to maturity of the Notes;

· the dividend rate on the equity securities included in the Reference Asset;

· interest and yield rates in the market generally;

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

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

Hypothetical Examples

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

Hypothetical Initial Level:	$100.00
Call Premiums:	12.50% of the Principal Amount if called on the first Observation Date, 25.00% if called on the second Observation Date and 37.50% if called on the Final Observation Date
Observation Dates:	July 20, 2018, June 25, 2019 and July 7, 2020
Hypothetical Trigger Level:	$80.00 (which is equal to 80.00% of the Hypothetical Initial Level)

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

Date	Official Closing Level	Payment (per Note)
First Observation Date	$130.00 (at or above Initial Level)	$1,125.00 (Payment at Redemption)
	Total Payment: $1,125.00 (12.50% return)

Since the Notes are called on the first Observation Date, HSBC will pay you on the applicable Call Settlement Date a total of $1,125.00 per $1,000 Note, reflecting your Principal Amount plus the Call Premium of $125.00. The total return on the Notes would be 12.50%. No further amount will be owed to you under the Notes.

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

Dates	Official Closing Level/Final Level	Payment (per Note)
First Observation Date	$90.00 (below Initial Level)	N/A
Second Observation Date	$87.00 (below Initial Level)	N/A
Final Valuation Date	$85.00 (at or above Trigger Level; below Initial Level)	$1,000.00 (Payment at Maturity)
	Total Payment: $1,000.00 (0.00% return)

Since the Notes are not called and the Final Level of the Reference Asset is above the Trigger Level, HSBC will pay you a total of $1,000 at maturity per $1,000 Note, reflecting your Principal Amount. The total return on the Notes would be 0.00%.

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

Dates	Official Closing Level/Final Level	Payment (per Note)
First Observation Date	$90.00 (below Initial Level)	N/A
Second Observation Date	$87.00 (below Initial Level)	N/A
Final Valuation Date	$60.00 (below Trigger Level)	$1,000 × (1 + Reference Return) =
		$1,000 × (1 + -40.00%) =
		$1,000 - $400.00 =
		$600.00 (Payment at Maturity)
	Total Payment $600.00 (-40.00% return)

Since the Notes are not called and the Final Level of the Reference Asset is below the Trigger Level, HSBC will pay you a total of $600.00 at maturity per $1,000 Note. The total loss on the Notes would be 40.00%.

Events of Default and Acceleration

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

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

Supplemental Plan of Distribution (Conflicts of Interest)

Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc., an affiliate of HSBC, will purchase the Notes from HSBC for distribution to JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC, acting as placement agents, at the price indicated on the cover of the pricing supplement, the document that will be filed pursuant to Rule 424(b)(2) containing the final pricing terms of the Notes. The placement agents for the Notes will receive a fee that will not exceed $20 per $1,000 Principal Amount. Certain fiduciary accounts purchasing the Notes will pay a purchase price of $980 per Note, and the placement agents with respect to sales made to such accounts will forgo any fees.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the Notes. However, it 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-59 in the prospectus supplement.

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, the Notes should be treated as pre-paid executory contracts with respect to the Reference Asset. 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, Morrison & Foerster LLP, it is reasonable to treat the Notes as pre-paid executory contracts with respect to the Reference Asset. 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 or exchange and we generally intend to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the Note for more than one year at such time for U.S. federal income tax purposes.

We will not attempt to ascertain whether any of the entities whose stock is included in the Reference Asset would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the Reference Asset were treated as a PFIC or USRPHC, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in the Reference Asset and consult your tax advisor regarding the possible consequences to you, if any, if one or more of the entities whose stock is included in the Reference Asset 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, U.S. Treasury regulations provide 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, 2018. 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 Reference Asset 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 Reference Asset 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.

Additionally, the IRS has announced that withholding under the Foreign Account Tax Compliance Act (as discussed in the accompanying prospectus supplement) on payments of gross proceeds from a sale, exchange, redemption, or other disposition of the Notes will only apply to dispositions after December 31, 2018.

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.
