All references to “Enhanced Market Participation Notes” in the accompanying product supplement shall refer to these Buffered Accelerated Market Participation Securities. Each offering of securities has the respective terms described in this pricing supplement and the accompanying product supplement, prospectus supplement, prospectus and relevant underlying supplement.  If the terms of the securities offered hereby are inconsistent with those described in the accompanying product supplement, prospectus supplement, prospectus or relevant underlying supplement, the terms described in this pricing supplement shall control.You should be willing to forgo interest and dividend payments during the term of the securities and, if the relevant Reference Return is negative, lose up to 90% of your principal.

This pricing supplement relates to multiple offerings of securities, each linked to the performance of a specific index or index fund (each index or index fund, a “Reference Asset”). Each of the four offerings of securities is linked to a different index or index fund and each of the four securities has a different Maximum Cap. The performance of each offering of securities does not depend on the performance of any other offering of securities.  The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to the relevant Reference Asset as described below.  The following key terms relate to the offerings of securities:

Issuer:	HSBC USA Inc.
Principal Amount:	$1,000 per security

Original Issue Date:	October 27, 2011
Final Valuation Date:	April 24, 2013.  The Final Valuation Date is subject to adjustment as described under “Additional Terms of the Notes” in the relevant accompanying underlying supplement.
Maturity Date:	3 business days after the Final Valuation Date, which is expected to be April 29, 2013.  The Maturity Date is subject to adjustment as described under “Additional Terms of the Notes” in the relevant accompanying underlying supplement.
Payment at Maturity:	On the Maturity Date, for each security, we will pay you the Final Settlement Value.

PS-2

Final Settlement Value:	If the relevant Reference Return is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, 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 relevant 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 of securities (zero return). If the relevant Reference Return is less than the Buffer Value, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, 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, because the buffer protects the first 10% of loss, if the Reference Return is -30%, you will suffer a 20% loss and receive 80% of the Principal Amount.  If the Reference Return is less than the Buffer Value, you may lose up to 90% of your investment.
Reference Return:	With respect to each Reference Asset, the quotient, expressed as a percentage, calculated as follows:
	Final Value – Initial Value           Initial Value
Buffer Value	With respect to each offering, -10%
Initial Value:	1,254.19 for the securities linked to the SPX, 736.03 for the securities linked to the RTY, $40.38 for the securities linked to the EEM and $56.03 for the securities linked to the GDX, in each case the Official Closing Value of the relevant Reference Asset on the Pricing Date.
Final Value:	With respect to each of the SPX and the RTY, the Official Closing Value of such Reference Asset on the Final Valuation Date.  With respect to the EEM and the GDX, the Official Closing Value of such Reference Asset on the Final Valuation Date, adjusted by the calculation agent as described under “Additional Terms of the Notes—Antidilution and Reorganization Adjustments” in the accompanying underlying supplement no. 4.
Official Closing Value:	The closing level or closing price, as applicable, of the Reference Asset on any scheduled trading day as determined by the calculation agent based upon the value displayed on the relevant Bloomberg Professional® service page (with respect to the SPX, “SPX <INDEX>”, with respect to the RTY, “RTY <INDEX>”, with respect to the EEM, “EEM UP <EQUITY>” and with respect to the GDX, “GDX UP <EQUITY>”) or, for each Reference Asset, any successor page on Bloomberg Professional® service or any successor service, as applicable.
Form of securities:	Book-Entry
Listing:	The securities will not be listed on any U.S. securities exchange or quotation system.

GENERAL

This pricing supplement relates to four separate security offerings, each linked to a different Reference Asset identified on the cover page.  The purchaser of a security will acquire a senior unsecured debt security of HSBC USA Inc. linked to a single Reference Asset.  Although each offering of securities relates to a Reference Asset identified on the cover page, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to such Reference Asset or any component security included in such Reference Asset or as to the suitability of an investment in the securities.

You should read this document together with the prospectus dated April 2, 2009, the prospectus supplement dated April 9, 2009, the product supplement dated April 9, 2009, and either underlying supplement no. 3 dated October 22, 2010 (for securities linked to the SPX or the RTY) or underlying supplement no. 4 dated October 22, 2010 (for securities linked to the EEM or the GDX), as applicable.  All references to “Enhanced Market Participation Notes” in the accompanying product supplement shall refer to these Buffered Accelerated Market Participation Securities. If the terms of the securities offered hereby are inconsistent with those described in the accompanying product supplement, prospectus supplement, prospectus, or relevant underlying supplement, the terms described in this pricing supplement shall control.  You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-6 of this pricing supplement, page PS-4 of the product supplement, page S-3 of the prospectus supplement and either page US3-1 of underlying supplement no. 3 or page US4-2 of underlying supplement no. 4 as applicable, as the securities involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities.  As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, a prospectus supplement, a product supplement and underlying supplements) with the SEC for the offering to which this pricing supplement relates.  Before you invest, you should read the prospectus and prospectus supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering.  You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov.  Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and product supplement if you request them by calling toll-free 1-866-811-8049.

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 relevant Reference Return is greater than zero, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, 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 relevant 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 of securities (zero return).

If the relevant Reference Return is less than the Buffer Value, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount of securities, 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, because the buffer protects the first 10% loss, subject to the credit risk of HSBC, if the

PS-4

Reference Return is -30%, you will suffer a 20% loss and receive 80% of the Principal Amount.  You should be aware that if the relevant Reference Return is less than the Buffer Value, you may lose up to 90% of your investment.

Interest

The securities will not pay periodic interest.

Calculation Agent

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

Trustee

Notwithstanding anything contained in the accompanying prospectus supplement or product supplement to the contrary, the securities will be issued under the senior indenture dated March 31, 2009, between HSBC USA Inc., as Issuer, and Wells Fargo Bank, National Association, as trustee.  Such indenture has substantially the same terms as the indenture described in the accompanying prospectus supplement.

Paying Agent

Notwithstanding anything contained in the accompanying prospectus supplement or product supplement to the contrary, HSBC Bank USA, N.A. will act as paying agent with respect to the securities pursuant to a Paying Agent and Securities Registrar Agreement dated June 1, 2009, between HSBC USA Inc. and HSBC Bank USA, N.A.

Reference Sponsor and Reference Issuer

With respect to securities linked to the SPX, Standard and Poor’s Financial Services LLC, a subsidiary of The McGraw-Hill Companies, Inc., is the reference sponsor.  With respect to securities linked to the RTY, the Russell Investment Group is the reference sponsor.  With respect to securities linked to the EEM, iShares, Inc. is the reference issuer. With respect to securities linked to the GDX, Market VectorsTM ETF Trust is the reference issuer.

} You are willing to make an investment that is exposed to the negative Reference Return on a 1-to-1 basis for each percentage point that the relevant Reference Return is less than -10%.

RISK FACTORS

We urge you to read the section “Risk Factors” on page S-3 in the accompanying prospectus supplement, on page PS-4 of the accompanying product supplement and on either page US3-1 of underlying supplement no. 3 or page US4-2 of underlying supplement no. 4, as applicable.  Investing in the securities is not equivalent to investing directly in any of the stocks comprising the relevant Reference Asset or the Reference Asset itself, as applicable.  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 pricing supplement and the accompanying product supplement, prospectus supplement , prospectus and relevant underlying supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement, product supplement and relevant underlying supplement including the explanation of risks relating to the securities described in the following sections:

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

} “— Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset” in the prospectus supplement;

If your securities are linked to the RTY:

} “— There are Risks Associated With Small-Capitalization Stocks” in underlying supplement no. 3;

If your securities are linked to the EEM or the GDX:

} “— Additional Risks Relating to Notes Linked to the Performance of Exchange-Traded Funds” in the product supplement;

If your securities are linked to the EEM:

} “— The Notes are Subject to Currency Exchange Risk” in underlying supplement no. 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 underlying supplement no. 4;

} “— There are Risks Associated with Emerging Markets” in underlying supplement no. 4;

If your securities are linked to the GDX:

} “— Additional Risks Relating to Notes with a Reference Asset That is a Commodity or a Contract or Index Relating thereto” in the prospectus supplement;

} “—Risks Associated With the Gold Mining Industry” in underlying supplement no. 4;

} “— There are Risks Associated With an Investment in a Concentrated Industry” in underlying supplement no. 4; and

} “— Small-Capitalization or Mid-Capitalization Companies Risk” in underlying supplement no. 4.

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 of -10%.  Accordingly, if the relevant Reference Return is less than -10%, your Payment at Maturity will be less than the Principal Amount of your securities.  You may lose up to 90% of your investment at maturity if the relevant Reference Return is negative.

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

You will not participate in any appreciation in the value of the relevant Reference Asset (as magnified by the Upside Participation Rate) beyond the relevant Maximum Cap.  The Maximum Cap is 16.50% with respect to the securities linked to the SPX, 24.00% with respect to the securities linked to the RTY, 23.00% with respect to the securities linked to the EEM and 27.00% with respect to the securities linked to the GDX. You will not receive a return on the securities greater than the relevant Maximum Cap.

PS-6

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.

An index fund and its underlying index are different.

The performance of an index fund may not exactly replicate the performance of its underlying index, because the index fund will reflect transaction costs and fees that are not included in the calculation of its underlying index.  It is also possible that an index fund may not fully replicate or may in certain circumstances diverge significantly from the performance of its underlying index due to the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments contained in the index fund or due to other circumstances. An index fund may use futures contracts, options, swap agreements, currency forwards and repurchase agreements in seeking performance that corresponds to its underlying index and in managing cash flows.

The Reference Assets that are index funds are subject to management risk.

The Reference Assets that are index funds are not managed according to traditional methods of ‘‘active’’ investment management, which involve the buying and selling of securities based on economic, financial and market analysis and investment judgment. Instead, the index funds, utilizing a ‘‘passive’’ or indexing investment approach, attempt to approximate the investment performance of their respective underlying indices by investing in a portfolio of securities that generally replicate the respective underlying index. Therefore, unless a specific security is removed from the respective underlying index, the respective index fund generally would not sell a security because the security’s issuer was in financial trouble. In addition, the index funds are subject to the risk that the investment strategy of the index funds’ investment advisors may not produce the intended results.

There is limited anti-dilution protection.

For certain events affecting shares of a Reference Asset that is an index fund, such as stock splits or extraordinary dividends, the calculation agent may make adjustments to the relevant Final Value which may affect your Final Settlement Value. However, the calculation agent is not required to make an adjustment for every corporate action which affects the shares of the relevant Reference Asset. If an event occurs that does not require the calculation agent to adjust the amount of the shares of the relevant Reference Asset, the market price of the securities and the Final Settlement Value may be materially and adversely affected.

The securities will not bear interest.

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

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

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

Please read and pay particular attention to the section “Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset” in the accompanying prospectus supplement.

The securities are not insured 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 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.

PS-7

Certain built-in costs are likely to adversely affect the value of the securities prior to maturity.

While the Payment at Maturity described in this pricing supplement is based on the full Principal Amount of your securities, the original issue price of the securities includes the placement agent’s commission and the estimated cost of HSBC hedging its obligations under the securities. As a result, the price, if any, at which HSBC Securities (USA) Inc. will be willing to purchase securities from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the Maturity Date could result in a substantial loss to you. The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity.

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.

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 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.

Uncertain tax treatment.

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

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 relevant Reference Asset relative to its Initial Value.  We cannot predict the Final Value of the relevant 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 relevant Reference Asset to which your securities are linked or the return on your securities.  With respect to the 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 those 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 performance for the relevant Reference Return from -100% to +100%. The following results are based solely on the assumptions outlined below.  The “Hypothetical Return on the Security” as used below is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 Principal Amount of securities 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:

}	Principal Amount:	$1,000
}	Upside Participation Rate:	200%
}	Hypothetical Maximum Cap:	16.50% (The actual Maximum Cap with respect to the securities linked to the SPX, is  16.50%, with respect to the securities linked to the RTY, is 24.00%, with respect to the securities linked to the EEM, is 23.00%, and with respect to the securities linked to the GDX, is 27.00%)

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 relevant Reference Return is 3.00%.

Reference Return:	3.00%
Final Settlement Value:	$1,060.00

Because the relevant 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 $1,060.00 per $1,000 Principal Amount of securities, calculated as follows:

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

= $1,000 + ($1,000 × 3.00% × 200%)

= $1,060.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the relevant Reference Return multiplied by 200% when such Reference Return is positive and such amount is equal to or less than the relevant Maximum Cap.

Example 2: The relevant Reference Return is 10.00%.

Reference Return:	10.00%
Final Settlement Value:	$1,165.00

Because the relevant 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 $1,165.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 16.50%)

= $1,165.00

Example 2 shows that you will receive the return of your principal investment plus a return equal to the Maximum Cap when the relevant Reference Return is positive and such Reference Return multiplied by 200% exceeds the relevant Maximum Cap.

Example 3: The relevant Reference Return is -5.00%.

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

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

Example 3 shows that you will receive the return of your principal investment where the value of the relevant Reference Asset declines by no more than 10% over the term of the securities.

Example 4: The relevant Reference Return is -30.00%.

Reference Return:	-30.00%
Final Settlement Value:		$800.00

Here, the relevant Reference Return is -30.00%.  Because the Reference Return is less than the Buffer Value of -10%, the Final Settlement Value would be $800.00 per $1,000 Principal Amount of securities, calculated as follows:

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

= $1,000 + [$1,000 × (-30.00% + 10%)]

= $800.00

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 Amount of -10%.  YOU MAY LOSE UP TO 90% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

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 forward or other executory contract with respect to the relevant 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.  Notwithstanding any disclosure in the accompanying product supplement to the contrary, our special U.S. tax counsel in this transaction is Sidley Austin llp. 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, Sidley Austin llp, it is reasonable to treat a security as a pre-paid forward or other executory contract with respect to the relevant 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 “Certain 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 and the GDX (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) of the U.S. holder determined as if the U.S. holder had acquired the Underlying Shares on the original issue date of the security at fair market value and sold them at fair market value on the Maturity Date (if the security was held until the Maturity Date) or on the date of sale or exchange of the security (if the security was sold or exchanged prior to the Maturity Date) (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).

Although the matter is not clear, there exists a risk that an investment in the securities linked to the EEM or the GDX 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 linked to the EEM or the GDX 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 linked to the EEM or the GDX will equal the excess of (i) any long-term capital gain recognized by the U.S. holder in respect of such a security 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”

PS-15

of the security 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, 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 relevant 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 relevant 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 relevant 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 relevant Reference Asset, as the case may be, is or becomes a PFIC or a USRPHC.

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