Information about the Reference Asset

The following graph illustrates the hypothetical daily historical performance of the SPX/RTY/EFA Basket from October 28, 2006 through October 28, 2011 based on information from Bloomberg Professional® service, if the level of the Basket was made to equal 100 on October 28, 2006. The hypothetical historical performance reflects the performance the Basket would have exhibited based on (i) the actual historical performance of the Reference Asset Components and (ii) the assumption that no adjustment to the Official Closing Value occurred from October 28, 2006 through October 28, 2011 for any Reference Asset Component. Neither the hypothetical historical performance of the Basket nor the actual historical performance of the Reference Asset Components should be taken as indications of future performance.

We cannot give you assurance that the performance of the Basket will result in the return of your initial investment. You may lose up to 80% of your investment.

Pricing Date:		November 18, 2011

Original Issue Date:		November 28, 2011

Final Valuation Date:		November 18, 2014, subject to adjustment as described below under the caption “Final Valuation Date and Maturity Date.”

Maturity Date:		5 business days after the Final Valuation Date, which is expected to be November 25, 2014. The Maturity Date is subject to adjustment as described below under the caption “Final Valuation Date and Maturity Date.”

Payment at Maturity:		On the Maturity Date, for each security, we will pay you the Final Settlement Value.

Component Weighting:		With respect to the SPX, 1/3, with respect to the RTY, 1/3 and with respect to the EFA, 1/3.

Final Settlement Value:

If the 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 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 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 + 20%)].

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 20% of loss, if the Reference Return is -30%, you will suffer a 10% loss and receive 90% of the Principal Amount. If the Reference Return is less than the Buffer Value, you may lose up to 80% of your investment.

We reserve the right to change the terms of, or reject any offer to purchase, the securities prior to their issuance. In the event of any material changes to the terms of the securities, we will notify you.

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 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 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 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 + 20%)].

FWP-6

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 20% loss, subject to the credit risk of HSBC, if the Reference Return is -30%, you will suffer a 10% loss and receive 90% of the Principal Amount. You should be aware that if the Reference Return is less than the Buffer Value, you may lose up to 80% of your investment.

RISK FACTORS

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

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying underlying supplement no. 3, the accompanying underlying supplement no. 4, the accompanying product supplement and the accompanying prospectus 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;

}	“— Additional Risks Relating to Certain Notes with More than One Instrument Comprising the Reference Asset” in the prospectus supplement;

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

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

}	“— 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; and

}	“— The Notes are Subject to Currency Exchange 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 -20%. Accordingly, if the Reference Return is less than -20%, your Payment at Maturity will be less than the Principal Amount of your securities. You may lose up to 80% of your investment at maturity if the Reference Return is negative.

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 (as magnified by the Upside Participation Rate) beyond the Maximum Cap. The Maximum Cap (to be determined on the Pricing Date) will not be less than 37.00% or greater than 41.00%. You will not receive a return on the securities greater than the Maximum Cap.

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 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 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 periodic interest payments.

No interest or dividend payments or voting rights.

As a holder of the securities, 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 the stocks comprising the Reference Asset Components or the Reference Asset Components themselves would have.

FWP-8

Changes in the values of the Reference Asset Components may offset each other.

Movements in the values of the Reference Asset Components may not correlate with each other. At a time when the value of one of the Reference Asset Components increases, the values of the other Reference Asset Components may not increase as much or may even decline. Therefore, in calculating the Final Value and therefore the Reference Return and Final Settlement Value, increases in the value of one or more of the Reference Asset Components may be moderated, or more than offset, by lesser increases or declines in the values of the other Reference Asset Components. As a result, the Final Settlement Value may be adversely affected even if the value of some of the Reference Asset Components increase during the term 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 the respective underlying index, because such index fund will reflect transaction costs and fees that are not included in the calculation of the respective 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 the respective underlying index due to the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments contained in such 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 the respective underlying index and in managing cash flows.

The Reference Asset is subject to management risk.

The index fund included in the Reference Asset is 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 fund, utilizing a ‘‘passive’’ or indexing investment approach, attempts to approximate the investment performance of its underlying index by investing in a portfolio of securities that generally replicate the underlying index. Therefore, unless a specific security is removed from the underlying index, the index fund generally would not sell a security because the security’s issuer was in financial trouble. In addition, the index fund is subject to the risk that the investment strategy of the index fund’s investment advisor may not produce the intended results.

There is limited anti-dilution protection.

For certain events affecting shares of an index fund, such as stock splits or extraordinary dividends, the calculation agent may make adjustments to the relevant Final Component 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 Component. If an event occurs that does not require the calculation agent to adjust the amount of the shares of the relevant Reference Asset Component, the market price of the securities and the Final Settlement Value may be materially and adversely affected.

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.

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 free writing prospectus 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.

FWP-9

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 the 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 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 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 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:	150%

}	Hypothetical Maximum Cap:	37.00% (The actual Maximum Cap will be determined on the Pricing Date and will not be less than 37.00% or greater than 41.00%)

Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Security
100.00%	$1,370.00	37.00%
80.00%	$1,370.00	37.00%
60.00%	$1,370.00	37.00%
40.00%	$1,370.00	37.00%
24.67%	$1,370.00	37.00%

5.00%	$1,075.00	7.50%
2.00%	$1,030.00	3.00%
1.00%	$1,015.00	1.50%
0.00%	$1,000.00	0.00%
-1.00%	$1,000.00	0.00%
-2.00%	$1,000.00	0.00%
-5.00%	$1,000.00	0.00%
-10.00%	$1,000.00	0.00%
-15.00%	$1,000.00	0.00%
-20.00%	$1,000.00	0.00%
-30.00%	$900.00	-10.00%
-40.00%	$800.00	-20.00%
-60.00%	$600.00	-40.00%
-80.00%	$400.00	-60.00%
-100.00%	$200.00	-80.00%

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 Reference Return is 5.00%.


Reference Return:	5.00%
Final Settlement Value:	$1,075.00

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 $1,075.00 per $1,000 Principal Amount of securities, calculated as follows:

FWP-11

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

= $1,000 + ($1,000 × 5.00% × 150%)

= $1,075.00

Example 1 shows that you will receive the return of your principal investment plus a return equal to the Reference Return multiplied by 150% when such Reference Return is positive and if such amount is equal to or less than the Maximum Cap.

Example 2: The Reference Return is 30.00%.


Reference Return:	30.00%
Final Settlement Value:	$1,370.00

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 $1,370.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + ($1,000 × Maximum Cap)

= $1,000 + ($1,000 × 37.00%)

= $1,370.00

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 150% exceeds the Maximum Cap.

Example 3: The Reference Return is -5.00%.


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

Because the Reference Return is less than zero but greater than the Buffer Value, 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 Reference Asset declines by no more than 20% over the term of the securities.

Example 4: The Reference Return is -30%.


Reference Return:	-30.00%
Final Settlement Value:		$900.00

Here, the Reference Return is -30.00%. Because the Reference Return is less than the Buffer Value of -20%, the Final Settlement Value would be $900.00 per $1,000 Principal Amount of securities, calculated as follows:

$1,000 + [$1,000 × (Reference Return + 20%)]

= $1,000 + [$1,000 × (-30.00% + 20%)]

= $900.00

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 -20%. YOU MAY LOSE UP TO 80% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

The SPX/RTY/EFA Basket

The following graph illustrates the hypothetical daily historical performance of the SPX/RTY/EFA Basket from October 30, 2006 through October 28, 2011 based on information from Bloomberg Professional® service, if the level of the Basket was made to equal 100 on October 30, 2006. The hypothetical historical performance reflects the performance the Basket would have exhibited based on (i) the actual historical performance of the Reference Asset Components and (ii) the assumption that no adjustment to the Official Closing Value occurred from October 30, 2006 through October 28, 2011 for any Reference Asset Component. Neither the hypothetical historical performance of the Basket nor the actual historical performance of the Reference Asset Components should be taken as indications of future performance.

We cannot give you assurance that the performance of the Basket will result in the return of your initial investment. You may lose up to 80% of your investment.

FINAL VALUATION DATE AND MATURITY DATE

If the Final Valuation Date is not a scheduled trading day for any Reference Asset Component, then the Final Valuation Date for such Reference Asset Component will be the next succeeding day that is a scheduled trading day (as defined in the relevant underlying supplement with respect to each Reference Asset Component) for such Reference Asset Component. For each Reference Asset Component, the calculation agent will determine whether a market disruption event (as defined in the relevant underlying supplement with respect to each Reference Asset Component) exists on the Final Valuation Date with respect to such Reference Asset Component independent from other Reference Asset Components; therefore a market disruption event may exist for certain Reference Asset Components and not exist for other Reference Asset Components. If a market disruption event exists for a Reference Asset Component on the Final Valuation Date, then the Final Valuation Date for such Reference Asset Component will be the next scheduled trading day for which there is no market disruption event for such Reference Asset Component. If such market disruption event continues for five consecutive scheduled trading days, then that fifth scheduled trading day will nonetheless be the Final Valuation Date for such Reference Asset Component, and the Final Component Value with respect to such Reference Asset Component will be determined (1) with respect to a Reference Asset Component that is an index, by means of the formula for and method of calculating such index which applied just prior to the market disruption event, using the relevant exchange’s traded or quoted price of each stock or other security included in such index (or if an event giving rise to a market disruption event has occurred with respect to a stock or other security in such index and is continuing on that fifth scheduled trading day, the calculation agent’s good faith estimate of the value for that stock or other security), or (2) with respect to a Reference Asset Component that is an index fund, by the calculation agent, in its sole discretion, using its estimate of the exchange traded prices for such index fund that would have prevailed but for that market disruption event. For the avoidance of doubt, if no market disruption event exists with respect to a Reference Asset Component on the originally scheduled Final Valuation Date, the determination of such Reference Asset Component’s Final Component Value will be made on the originally scheduled Final Valuation Date, irrespective of the existence of a market disruption event with respect to any other Reference Asset Component. If the Final Valuation Date for any Reference Asset Component is postponed, then the Maturity Date will also be postponed to the fifth business day following the latest of such postponed Final Valuation Dates.

FWP-15

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 at Maturity due and payable in the same general manner as described in “Payment at Maturity” in this free writing prospectus. In such a case, the third scheduled trading day for all of the Reference Asset Components immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the accelerated Reference Asset Component Return for each Reference Asset Component. If a market disruption event exists with respect to a Reference Asset Component on that scheduled trading day, then the accelerated Final Valuation Date will be postponed for up to five scheduled trading days (in the same general manner used for postponing the originally scheduled Final Valuation Date). The accelerated Maturity Date will be the fifth business day following such accelerated postponed Final Valuation Date.

For more information, see “Description of 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 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 offering price set forth on the cover page of this free writing prospectus and will receive underwriting discounts and commissions of up to 2.15%, or $21.50, per $1,000 Principal Amount of securities. HSBC Securities (USA) Inc. may allow selling concessions on sales of such securities by other brokers or dealers of up to 2.15%, or $21.50 per $1,000 Principal Amount of securities.

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 these 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 do so and may discontinue any market-making activities at any time without notice.

See “Supplemental Plan of Distribution” on page S-52 in the prospectus supplement. All references to NASD Rule 2720 in the prospectus supplement shall be to FINRA Rule 5121.

We expect that delivery of the securities will be made against payment for the securities on or about the Original Issue Date set forth on page FWP-2 of this document, which is expected to be the fifth business day following the Trade Date of the securities. Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade securities on the Trade Date and the following business day thereafter will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

There is no direct legal authority as to the proper tax treatment of the 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 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 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 EFA). Under the “constructive ownership”

FWP-16

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 (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 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. 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 the issuer of any stock included in, or owned by, one or more of the Reference Asset Components would be treated as either a “passive foreign investment company” (“PFIC”) or a United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. In the event that the issuer of any stock included in, or owned by, one or more of the Reference Asset Components 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 issuers of stock included in, or owned by, the Reference Asset Components and consult your tax advisor regarding the possible consequences to you in the event that one or more issuers of stock included in, or owned by, one or more of the Reference Asset Components is or becomes a PFIC or 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.
