FWP-6

PAYMENT AT MATURITY

On the Maturity Date, for each security you hold, we will pay you the Final Settlement Value, which is an amount in cash, as described below:

If the Reference Return is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, equal to the lesser of:

(a) $1,000 + ($1,000 × Reference Return × Upside Participation Rate); and

(b) $1,000 + ($1,000 × Maximum Cap).

If the Reference Return is less than or equal to zero but greater than or equal to the Buffer Value, you will receive $1,000 per $1,000 Principal Amount (zero return).

If the Reference Return is less than the Buffer Value, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × (Reference Return + 10%)).

Under these circumstances, you will lose 1% of the Principal Amount of your securities for each percentage point that the Reference Return is below the Buffer Value. For example, if the Reference Return is -50%, you will suffer a 40% loss and receive 90% of the Principal Amount, subject to the credit risk of HSBC. You should be aware that if the Reference Return is less than the Buffer Value, you will lose up to 90% of your investment.

Interest

The securities will not pay interest.

Calculation Agent

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

Reference Sponsors and Reference Issuer

With respect to the SX5E, Deutsche Börse AG and SIX Group AG are the reference sponsors. With respect to the MID, S&P Dow Jones Indices LLC, a part of McGraw-Hill Financial, is the reference sponsor. With respect to the EEM, iShares, Inc. is the reference issuer.

FWP-7

4 You seek an investment with a return linked to the potential positive performance of the Reference Asset and you believe the value of the Reference Asset will increase over the term of the securities.

4 You are willing to invest in the securities based on the Maximum Cap indicated herein, which may limit your return at maturity. The actual Maximum Cap for the offering of securities will be determined on the Pricing Date.

FWP-8

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement, page S-2 of the accompanying Equity Index Underlying Supplement and page S-1 of the accompanying ETF Underlying Supplement. Investing in the securities is not equivalent to investing directly in the EEM or in any of the stocks comprising or held by any Reference Asset Component. You should understand the risks of investing in the securities and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the securities in light of your particular financial circumstances and the information set forth in this free writing prospectus and the accompanying Equity Index Underlying Supplement, prospectus supplement and prospectus.

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

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

4 “—General Risks Related to Indices” in the Equity Index Underlying Supplement;

4 “— General Risks Related to Index Funds” in the ETF Underlying Supplement;

4 “—Securities Prices Generally Are Subject to Political, Economic, Financial and Social Factors that Apply to the Markets in which They Trade and, to a Lesser Extent, Foreign Markets” in the Equity Index Underlying Supplement and the ETF Underlying Supplement; and

4 “—Time Differences Between the Domestic and Foreign Markets and New York City May Create Discrepancies in the Trading Level or Price of the Notes” in the Equity Index Underlying Supplement and the ETF Underlying Supplement;

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

Your investment in the securities may result in a loss.

You will be exposed to the decline in the Final Value from the Initial Value beyond the Buffer Value. Accordingly, if the Reference Return is less than the Buffer Value, your Payment at Maturity will be less than the Principal Amount of your securities. You will lose up to 90% of your investment at maturity if the Reference Return is less than the Buffer Value.

The appreciation on the securities is limited by the Maximum Cap.

You will not participate in any appreciation in the value of the Reference Asset beyond the Maximum Cap. The Maximum Cap (to be determined on the Pricing Date) will be at least 19%. You will not receive a return on the securities greater than the Maximum Cap.

The amount payable on the securities is not linked to the value of the Reference Asset at any time other than on the Final Valuation Date.

The Final Value of the Reference Asset will be based on the Official Closing Values of each Reference Asset Component on the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the value of the Reference Asset appreciates prior to the Final Valuation Date but then decreases on the Final Valuation Date to a value that is equal to or less than the Initial Value, the Payment at Maturity will be less, and may be significantly less, than it would have been had the Payment at Maturity been linked to the value of the Reference Asset prior to that decrease. Although the actual value of the Reference Asset on the Maturity Date or at other times during the term of the securities may be higher than the Final Value, the Payment at Maturity will be based solely on the Official Closing Values of the Reference Asset Components on the Final Valuation Date.

Mid-capitalization risk.

The MID tracks companies that may be considered mid-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the respective index level may be more volatile than an investment in stocks issued by larger companies. Stock prices of mid-capitalization companies may also be more vulnerable than those of larger companies to adverse business and economic developments, and the stocks of mid-capitalization companies may be thinly traded, making it difficult for the MID to track them. In addition, mid-capitalization companies are often less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Mid-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. These companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and competitive strengths than large-capitalization companies, and are more susceptible to adverse developments related to their products.

FWP-9

Risks associated with non-U.S. companies.

The value of the EEM depend 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. 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 Components and, as a result, the value of the Notes.

Risks associated with emerging markets.

Because the EEM is a Reference Asset Component, an investment in the Notes will involve risks not generally associated with investments which have no emerging market component. In particular, many emerging nations are undergoing rapid change, involving the restructuring of economic, political, financial and legal systems. Regulatory and tax environments may be subject to change without review or appeal. Many emerging markets suffer from underdevelopment of capital markets and tax regulation. The risk of expropriation and nationalization remains a threat. Guarding against such risks is made more difficult by low levels of corporate disclosure and unreliability of economic and financial data.

The Notes will not be adjusted for changes in exchange rates.

Although the equity securities held by the EEM are traded in currencies other than U.S. dollars, and your securities are denominated in U.S. dollars, the amount payable on the Notes at maturity, if any, will not be adjusted for changes in the exchange rates between the U.S. dollar and the currencies in which these non-U.S. equity securities are denominated. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the value of the EEM, and therefore the Notes. The amount we pay in respect of the Notes on the maturity date, if any, will be determined solely in accordance with the procedures described in this pricing supplement.

Credit risk of HSBC USA Inc.

The securities 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 securities will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law. Any payment to be made on the securities, including any 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 securities 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 securities.

The securities will not bear interest.

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

A change in the value of one or more Reference Asset Components may be offset by a change in the values of the other Reference Asset Components.

A change in the value of one or more Reference Asset Components as of each Observation Date, including the Final Valuation Date, may not correlate with a change in the values of the other Reference Asset Components. The value of one or more Reference Asset Components may increase, while the values of the other Reference Asset Components may not increase as much, or may even decrease. Therefore, in calculating the value of the Reference Asset, an increase in the value of one or more Reference Asset Components may be moderated, or wholly offset, by lesser increases or decreases in the values of the other Reference Asset Components. This effect is further amplified by the differing weights of the Reference Asset Components.

Changes that affect the Reference Asset will affect the market value of the securities and the amount you will receive at maturity.

The policies of the applicable reference sponsor concerning additions, deletions and substitutions of the constituents comprising the relevant Reference Asset Component and the manner in which the applicable reference sponsor takes account of certain changes affecting those constituents may affect the value of that Reference Asset Component. The policies of the applicable reference sponsor or reference issuer with respect to the calculation of the relevant Reference Asset Component could also affect the value of that Reference Asset Component. The applicable reference sponsor or reference issuer may discontinue or suspend calculation or dissemination of the relevant Reference Asset Component. Any such actions could affect the value of the securities and the return on the securities.

FWP-10

The performance and market value of the EEM during periods of market volatility may not correlate with the performance of its underlying index as well as the net asset value per share of the EEM.

During periods of market volatility, securities underlying the EEM may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of the EEM and the liquidity of the EEM may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares of the EEM. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of the EEM. As a result, under these circumstances, the market value of shares of the EEM may vary substantially from the net asset value per share of the EEM. For all of the foregoing reasons, the performance of the EEM may not correlate with the performance of its underlying index as well as the net asset value per share of the EEM, which could materially and adversely affect the value of the securities in the secondary market and/or reduce your payment at maturity.

The securities are not insured or guaranteed by any governmental agency of the United States or any other jurisdiction.

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

The Estimated Initial Value of the securities, 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 securities in the secondary market, if any.

The Estimated Initial Value of the securities 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 securities. 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 securities may be lower if it were based on the levels at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the securities to be more favorable to you. We will determine the value of the embedded derivatives in the securities by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the securities that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your securities in the secondary market (if any exists) at any time.

The price of your securities in the secondary market, if any, immediately after the Pricing Date will 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 securities and the costs associated with structuring and hedging our obligations under the securities. If you were to sell your securities in the secondary market, if any, the price you would receive for your securities may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the value of the Reference Asset and changes in market conditions, and cannot be predicted with accuracy. The securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the securities to maturity. Any sale of the securities prior to maturity could result in a loss to you.

If we were to repurchase your securities immediately after the Original Issue Date, the price you receive may be higher than the Estimated Initial Value of the securities.

Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the securities in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed the Estimated Initial Value on the Pricing Date for a temporary period expected to be approximately 5 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 securities and other costs in connection with the securities that we will no longer expect to incur over the term of the securities. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the securities and any agreement we may have with the distributors of the securities. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the securities based on changes in market conditions and other factors that cannot be predicted.

The securities lack liquidity.

The securities will not be listed on any securities exchange. HSBC Securities (USA) Inc. is not required to offer to purchase the securities 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 securities easily. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the securities.

Potential conflicts of interest may exist.

HSBC and its affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other

FWP-11

affiliates of ours are potentially adverse to your interests as an investor in the securities. We will not have any obligation to consider your interests as a holder of the securities in taking any action that might affect the value of your securities.

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 the Reference Asset relative to its Initial Value. We cannot predict the Final Value of the Reference Asset. 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 Reference Asset or the return on your securities. 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 on a $1,000 investment in the securities for a hypothetical range of Reference Returns from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Securities” 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 securities are held to maturity. You should consider carefully whether the securities are suitable to your investment goals. The following table and examples assume the following:

4	Principal Amount:	$1,000
4	Hypothetical Maximum Cap:	19% (The actual Maxmium Cap will be determined on the Pricing Date and will be at least 19%)
4	Initial Value:	100
4	Upside Participation Rate:	115%
4	Buffer Value:	-10%

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

Example 1: The value of the Reference Asset increases from the Initial Value of 100.00 to a Final Value of 110.00.

Reference Return:	10.00%
Final Settlement Value:	$1,115.00

Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is less than the hypothetical Maximum Cap, the Final Settlement Value would be $1,115.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Reference Return × Upside Participation Rate)

= $1,000 + ($1,000 × 10.00% × 115%)

= $1,115.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by 115% when the Reference Return is positive and, as multiplied by the Upside Participation Rate, equal to or less than the Maximum Cap.

Example 2: The Reference Return is 60.00%.

Reference Return:	60.00%
Final Settlement Value:	$1,190.00

Because the Reference Return is positive, and such Reference Return multiplied by the Upside Participation Rate is greater than the hypothetical Maximum Cap, the Final Settlement Value would be $1,190.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 19.00%)

= $1,190.00

Example 2 shows that you will receive the return of your principal investment plus a return equal to the Maximum Cap when the Reference Return is positive and such Reference Return multiplied by 115% exceeds the Maximum Cap.

Example 3: The value of the Reference Asset decreases from the Initial Value of 100.00 to a Final Value of 95.00.

Reference Return:	-5.00%
Final Settlement Value:	$1,000.00

Because the Reference Return is less than zero but greater than the Buffer Value of -10%, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 4: The value of the Reference Asset decreases from the Initial Value of 100.00 to a Final Value of 60.00.

Reference Return:	-40.00%
Final Settlement Value:	$700.00

Because the Reference Return is less than the Buffer Value of -10%, the Final Settlement Value would be $700.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 10%)]

= $1,000 + [$1,000 × (-40.00% + 10%)]

= $700.00

Example 4 shows that you are exposed on a 1-to-1 basis to declines in the value of the Reference Asset beyond the Buffer Value of -10%. YOU MAY LOSE UP TO 90% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

Hypothetical Performance of the Reference Asset

The following graph illustrates the hypothetical daily historical performance of the Reference Asset from January 1, 2008 through November 25, 2015 based on closing value information from the Bloomberg Professional^® service, if the value of the Reference Asset was made to equal 100 on January 1, 2008. The hypothetical historical performance reflects the performance the Reference Asset would have exhibited based on the actual historical performance of the Indices. Neither the hypothetical historical performance of the Reference Asset nor the actual historical performance of any Index should be taken as indications of future performance.

We cannot give you assurance that the performance of the Reference Asset will result in the return of your initial investment. You may lose up to 90% of your investment.

EVENTS OF DEFAULT AND ACCELERATION

If the securities have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the securities, the calculation agent will determine the accelerated payment due and payable at maturity in the same general manner as described in “Payment at Maturity” in this free writing prospectus. In that case, the scheduled trading day immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the Reference Return, 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 any Reference Asset Component on that scheduled trading day, then the accelerated Final Valuation Date for that Reference Asset Component 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 a Reference Asset Component on the scheduled trading day immediately preceding the date of acceleration, the determination of that Reference Asset Component’s Final Component Level will be made on such date, irrespective of the existence of a Market Disruption Event with respect to the another Reference Asset Component occurring on that date.

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

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the securities. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the securities from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this free writing prospectus relates, for distribution to other registered broker-dealers, or will offer the securities directly to investors. HSBC Securities (USA) Inc. proposes to offer the securities at the price to public set forth on the cover page of this free writing prospectus. HSBC USA Inc. or one of our affiliates may pay an underwriting discount of up to 1.50% per $1,000 Principal Amount in connection with the distribution of the securities to other registered broker-dealers. Neither HSBC USA Inc. nor any of its affiliates will pay any underwriting discounts.

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 securities.

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

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-59 in the prospectus supplement.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

There is no direct legal authority as to the proper tax treatment of the securities, and therefore significant aspects of the tax treatment of the securities are uncertain as to both the timing and character of any inclusion in income in respect of the securities. Under one approach, a security should be treated as a pre-paid executory contract with respect to the Reference Asset. We intend to treat the securities consistent with this approach. Pursuant to the terms of the securities, you agree to treat the securities under this approach for all U.S. federal income tax purposes. Subject to 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 a security as a pre-paid executory contract with respect to the Reference Asset. Pursuant to this approach and subject to the discussion below regarding “constructive ownership transactions,“ we do not intend to report any income or gain with respect to the securities prior to their maturity or an earlier sale or exchange and we 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 security for more than one year at such time for U.S. federal income tax purposes.

Despite the foregoing, U.S. holders (as defined under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement) should be aware that the Internal Revenue Code of 1986, as amended (the “Code”), contains a provision, Section 1260 of the Code, which sets forth rules which are applicable to what it refers to as “constructive ownership transactions.” Due to the manner in which it is drafted, the precise applicability of Section 1260 of the Code to any particular transaction is often uncertain. In general, a “constructive ownership transaction” includes a contract under which an investor will receive payment equal to or credit for the future value of any equity interest in a regulated investment company (such as shares of the EEM (the “Underlying Shares”)). Under the “constructive ownership” rules, if an investment in the securities is treated as a “constructive ownership transaction,” any long-term capital gain recognized by a U.S. holder in respect of a security will be recharacterized as ordinary income to the extent such gain exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Code) (the “Excess Gain”). In addition, an interest charge will also apply to any deemed underpayment of tax in respect of any Excess Gain to the extent such gain would have resulted in gross income inclusion for the U.S. holder in taxable years prior to the taxable year of the sale, exchange or maturity of the security (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale, exchange or maturity of the security). Furthermore, unless otherwise established by clear and convincing evidence, the “net underlying long-term capital gain” is treated as zero.

Although the matter is not clear, there exists a risk that an investment in the securities will be treated as a “constructive ownership transaction.” If such treatment applies, it is not entirely clear to what extent any long-term capital gain recognized by a U.S. holder in respect of a security will be recharacterized as ordinary income. It is possible, for example, that the amount of the Excess Gain (if any) that would be recharacterized as ordinary income in respect of each security will equal the excess of (i) any long-term capital gain recognized by the U.S. holder in respect of such a security and attributable to the Underlying Shares over (ii) the “net underlying long-term capital gain” such U.S. holder would have had if such U.S. holder had acquired a number of the Underlying Shares at fair market value on the Original Issue Date of such security for an amount equal to the “issue price” of the security allocable to the Underlying Shares and, upon the date of sale, exchange or maturity of the security, sold such Underlying Shares at fair market value (which would reflect the percentage increase in the value of the Underlying Shares over the term of the security). Accordingly, it is possible that all or a portion of any gain upon maturity, sale or exchange of a security after one year could be treated as “Excess Gain” from a “constructive ownership transaction,” which gain would be recharacterized as ordinary income, and subject to an interest charge. U.S. holders should consult their tax advisors regarding the potential application of the “constructive ownership” rules.

We will not attempt to ascertain whether any of the entities whose stock is included in, or owned by, the Reference Asset, as the case may be, 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, or owned by, the Reference Asset, as the case may be, were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in, or owned by, the Reference Asset, as the case may be, and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in, or owned by, the Reference Asset, as the case may be, 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 securities 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 securities.

Recently finalized Treasury Regulations provide that withholding on “dividend equivalent” payments (as discussed in the accompanying prospectus supplement), if any, will not apply to securities issued before January 1, 2016. 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 or redemption of the securities will only apply to payments made after December 31, 2018.

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