Contingent Income Auto-Callable Securities due April 4, 2013

Based on the Performance of the iShares^® MSCI Emerging Markets Index Fund

Contingent Income Auto-Callable Securities offer the opportunity for investors to earn a contingent quarterly payment equal to 2.00% of the stated principal amount, with respect to each determination date on which the closing price of the underlying shares is greater than or equal to 75% of the initial share price, which we refer to as the downside threshold level. In addition, if the closing price of the underlying shares is greater than or equal to the initial share price on any of the first three determination dates, the securities will be automatically redeemed for an amount per security equal to the sum of the stated principal amount and the contingent quarterly payment with respect to the related determination date. If the securities have not been previously redeemed and the final share price is greater than or equal to the downside threshold level, the payment at maturity will be the sum of the stated principal amount and the contingent quarterly payment with respect to the final determination date. However, if the securities have not been previously redeemed and the final share price is less than the downside threshold level, you will be exposed to the decline in the closing price of the underlying shares, as compared to the initial share price, on a 1 to 1 basis and will receive an amount which will be substantially less than the stated principal amount of the securities and which could be zero. As a result, investors must be willing to accept the risk of losing their entire principal and also the risk of not receiving any contingent quarterly payment. Accordingly, the securities do not guarantee any return of principal at maturity. Investors will not participate in any appreciation of the underlying shares. All payments on the securities are subject to the credit risk of HSBC.

General Information
Listing:	The securities will not be listed on any securities exchange.

ISIN:	US40433K2318
Minimum ticketing size:	$1,000 / 100 securities
Tax considerations:	Prospective investors should note that the discussion under the section called “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement does not apply to the securities issued under this document and is superseded by the following discussion. The following summary is a general discussion of the material U.S. federal tax consequences of ownership and disposition of the securities. This discussion applies only to initial investors in the securities who:

· purchase the securities at their “issue price”; and

· will hold the securities as capital assets, within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”).

This discussion does not describe all of the tax consequences that may be relevant to a holder in light of the holder’s particular circumstances or to holders subject to special rules, such as:

· certain financial institutions;

· insurance companies;

· certain dealers and traders in securities, commodities or foreign currencies;

· investors holding the securities as part of a “straddle,” conversion transaction, integrated transaction or constructive sale transaction;

· U.S. Holders, as defined below, whose functional currency is not the U.S. dollar;

· partnerships or other entities classified as partnerships for U.S. federal income tax purposes;

· regulated investment companies;

· real estate investment trusts;

· tax-exempt entities, including an “individual retirement account” or “Roth IRA”, as defined in Section 408 or 408A of the Code, respectively; or

· persons subject to the alternative minimum tax.

As the law applicable to the U.S. federal income taxation of instruments such as the securities is technical and complex, the discussion below necessarily represents only a general summary. Moreover, the effect of any applicable state, local or foreign tax laws is not discussed.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof, changes to any of which subsequent to the date of this document may affect the tax consequences described herein. Persons considering the purchase of the securities should consult their tax advisers with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

General

Pursuant to the terms of the securities, you agree to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a contingent quarterly payment that will be treated as gross income to you at the time received or accrued in accordance with your regular method of tax accounting.

Due to the absence of statutory, judicial or administrative authorities that directly address the treatment of the securities or instruments that are similar to the securities for U.S. federal income tax purposes, no assurance can be given that the Internal Revenue Service (the “IRS”) or the courts will agree with the tax treatment described herein. Accordingly, you should consult your tax advisers regarding all aspects of the U.S. federal tax consequences of an investment in the securities (including possible alternative treatments of the securities) and with respect to any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. Unless otherwise stated, the following discussion is based on the treatment

March 2012 Page 3

 

Contingent Income Auto-Callable Securities due April 4, 2013

Based on the Performance of the iShares^® MSCI Emerging Markets Index Fund

of each security as described in the previous paragraph.

Tax Consequences to U.S. Holders

This section applies to you only if you are a U.S. Holder. As used herein, the term “U.S. Holder” means a beneficial owner of a security that is, for U.S. federal income tax purposes:

· a citizen or individual resident of the United States;

· a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia; or

· an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

The term “U.S. Holder” also includes certain former citizens and residents of the United States.

Tax Treatment of the Securities

Assuming the treatment of the securities as set forth above is respected, the following U.S. federal income tax consequences should result.

Tax Basis. A U.S. Holder’s tax basis in the securities should equal the amount paid by the U.S. Holder to acquire the securities.

Tax Treatment of Contingent Quarterly Payment. Any contingent quarterly payment on the securities should be taxable as ordinary income to a U.S. Holder at the time received or accrued in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.

Sale, Exchange, Early Redemption or Settlement of the Securities. Upon a sale, exchange, early redemption or settlement of the securities at maturity, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized (other than with respect to cash attributable to the contingent quarterly coupon, which should be treated as discussed above) on the sale, exchange, early redemption or settlement and the U.S. Holder’s tax basis in the securities sold, exchanged, redeemed or settled. Any such gain or loss should be short-term capital gain or loss.

Possible Alternative Tax Treatments of an Investment in the Securities

Due to the absence of authorities that directly address the proper tax treatment of the securities, no assurance can be given that the IRS will accept, or that a court will uphold, the tax treatment described above. In particular, the IRS could seek to treat a security as a short-term debt instrument. Under such treatment, the timing and character of income thereon would be significantly affected. Among other things, gain realized by a U.S. Holder upon early redemption or settlement of a security at maturity would be treated as ordinary income. In addition, such a security would be treated as issued with original issue discount equal to the difference between the security’s stated redemption price at maturity and its issue price, and as a result (1) gain recognized by a U.S. Holder upon sale or exchange of the security would be treated as ordinary income to the extent of any accrued original issue discount, and (2) accrual-method U.S. Holders (and cash-method U.S. Holders that elect to apply an accrual method of tax accounting to the securities) would be required to accrue as ordinary income original issue discount over the term of the security before maturity. However, the amount of accrued original issue discount would be unclear because the amount payable at maturity of the security is not known as of the issue date.

Other alternative federal income tax treatments of the securities are also possible, which if applied could also affect the timing and character of the income or loss with respect to the securities. On December 7, 2007, the Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses on whether to require holders of “prepaid forward contracts” and similar instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether short-term instruments should be subject to any such accrual regime; the relevance of factors such as the exchange–traded status of the instruments and the nature of the underlying property to which the instruments are linked; whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose an interest charge; and appropriate transition rules and effective dates. While it is not clear whether instruments such as the securities would be viewed as similar to the prepaid forward contracts described in the notice, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax

Contingent Income Auto-Callable Securities due April 4, 2013

Based on the Performance of the iShares^® MSCI Emerging Markets Index Fund

consequences of an investment in the securities, possibly with retroactive effect. U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments and the issues presented by this notice.

Backup Withholding and Information Reporting

Backup withholding may apply in respect of the amounts paid to a U.S. Holder, unless such U.S. Holder provides proof of an applicable exemption or a correct taxpayer identification number, or otherwise complies with applicable requirements of the backup withholding rules. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the U.S. Holder’s U.S. federal income tax liability, provided that the required information is furnished to the IRS.  In addition, information returns may be filed with the IRS in connection with payments on the securities and the proceeds from a sale, exchange, early redemption or other disposition of the securities, unless the U.S. Holder provides proof of an applicable exemption from the information reporting rules.

Tax Consequences to Non-U.S. Holders

This section applies to you only if you are a Non-U.S. Holder. As used herein, the term “Non-U.S. Holder” means a beneficial owner of a security that is for U.S. federal income tax purposes:

· an individual who is classified as a nonresident alien;

· a foreign corporation; or

· a foreign trust or estate.

The term “Non-U.S. Holder” does not include any of the following holders:

· a holder who is an individual present in the United States for 183 days or more in the taxable year of disposition and who is not otherwise a resident of the United States for U.S. federal income tax purposes;

· certain former citizens or residents of the United States; or

· a holder for whom income or gain in respect of the securities is effectively connected with the conduct of a trade or business in the United States.

Such holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities.

Although significant aspects of the tax treatment of each security are uncertain, we intend to withhold on any contingent quarterly payment made to a Non-U.S. Holder generally at a rate of 30% or at a reduced rate specified by an applicable income tax treaty under an “other income” or similar provision. We will not be required to pay any additional amounts with respect to amounts withheld. In order to claim an exemption from or a reduction in the 30% withholding tax, a Non-U.S. Holder of the securities must comply with certification requirements to establish that it is not a U.S. person and is eligible for a reduction of, or an exemption from withholding under, an applicable tax treaty. If you are a Non-U.S. Holder, you should consult your tax advisers regarding the tax treatment of the securities, including the possibility of obtaining a refund of any withholding tax and the certification requirement described above.

U.S. Federal Estate Tax

Individual Non-U.S. Holders and entities the property of which is potentially includible in such an individual’s gross estate 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 may be treated as U.S. situs property subject to U.S. federal estate tax. Prospective investors that are non-U.S. individuals, or are entities of the type described above, should consult their tax advisers regarding the U.S. federal estate tax consequences of an investment in the securities.

Backup Withholding and Information Reporting

Information returns may be filed with the IRS in connection with payments on the securities and the proceeds from a sale, exchange, early redemption or other disposition. A Non-U.S. Holder may be subject to backup withholding in respect of amounts paid to the Non-U.S. Holder, unless such Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person for U.S. federal income tax purposes or otherwise establishes an exemption. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is furnished to the IRS.

Hypothetical Examples

The below examples are based on the following terms:

Initial Share Price:	$42.94
Downside Threshold Level:	75% of the initial share price
Contingent Quarterly Payment:	$0.2000 (2.00% of the stated principal amount)
Stated Principal Amount:	$10 per security

In Examples 1 and 2, the closing price of the underlying shares fluctuates over the term of the securities and the determination closing price of the underlying shares is greater than or equal to the initial share price of $42.94 on one of the first three determination dates. Because the determination closing price is greater than or equal to the initial share price on one of the first three determination dates, the securities are automatically redeemed following the relevant determination date. In Examples 3 and 4, the determination closing price on the first three determination dates is less than the initial share price, and, consequently, the securities are not automatically redeemed prior to, and remain outstanding until, maturity.

	Example 1			Example 2
Determination Dates	Hypothetical Determination Closing Price	Contingent Quarterly Payment	Early Redemption Amount*	Hypothetical Determination Closing Price	Contingent Quarterly Payment	Early Redemption Amount
#1	$42.94	—*	$10.2000	$35.00	$0.2000	N/A
#2	N/A	N/A	N/A	$15.00	$0	N/A
#3	N/A	N/A	N/A	$53.68	—*	$10.2000
Final Determination Date	N/A	N/A	N/A	N/A	N/A	N/A

* The Early Redemption Amount includes the unpaid contingent quarterly payment with respect to the determination date on which the determination closing price is greater than or equal to the initial share price and the securities are redeemed as a result.

§ In Example 1, the securities are automatically redeemed following the first determination date as the determination closing price on the first determination date is equal to the initial share price. You receive the early redemption payment, calculated as follows:

stated principal amount + contingent quarterly payment = $10 + $0.2000 = $10.2000

In this example, the early redemption feature limits the term of your investment to approximately 3 months and you may not be able to reinvest at comparable terms or returns. If the securities are redeemed early, you will stop receiving contingent payments.

§ In Example 2, since the determination closing price on the first determination date is greater than the downside threshold level, you receive the contingent payment of $0.2000 with respect to such determination date. The securities are automatically redeemed following the third determination date, as the determination closing price on the third determination date is greater than the initial share price. Following the third determination date, you receive an early redemption amount of $10.2000, which includes the contingent quarterly payment with respect to the third determination date.

In this example, the early redemption feature limits the term of your investment to approximately 9 months and you may not be able to reinvest at comparable terms or returns. If the securities are redeemed early, you will stop receiving contingent payments. Further, although the underlying shares has appreciated by approximately 25% from its initial share price on the third determination date, you only receive $10.2000 per security and do not benefit from such appreciation.

	Example 3			Example 4

Final Determination Date	$18.00	$0	N/A	$34.35	$0.2000*	N/A
Payment at Maturity	$4.19			$10.2000

* The final contingent quarterly payment, if any, will be paid at maturity.

Examples 3 and 4 illustrate the payment at maturity per security based on the final share price.

§ In Example 3, the closing price of the underlying shares remains below the downside threshold level throughout the term of the securities. As a result, you do not receive any contingent payments during the term of the securities and, at maturity, you are fully exposed to the decline in the closing price of the underlying shares. As the final share price is less than the downside threshold level, you will lose 1% for every 1% decline in the price of the underlying shares from the pricing date to the final determination date, calculated as follows:

$10 x the share performance factor = $10 x (final share price / initial share price) = $10 x (18/42.94) = $10 x 0.419 = $4.19

In this example, the payment you receive at maturity is significantly less than the stated principal amount.

§ In Example 4, the closing price of the underlying shares decreases to a final share price of $34.35. Although the final share price is less than the initial share price, because the final share price is still not less than the downside threshold level, you receive the stated principal amount plus a contingent quarterly payment with respect to the final determination date. Your payment at maturity is calculated as follows:

$10 + $0.2000 = $10.2000

In this example, although the final share price represents an approximate 20% decline from the initial share price, you receive the stated principal amount per security plus the contingent quarterly payment, equal to a total payment of $10.2000 per security at maturity.

Risk Factors

We urge you to read the section “Risk Factors” on page S-3 in the accompanying prospectus supplement and on page S-2 of ETF Underlying Supplement. Investing in the securities is not equivalent to investing directly in the underlying shares or any of the stocks composing the underlying index. 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 ETF Underlying Supplement, prospectus supplement and prospectus.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and ETF 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;

“—General risks related to Index Funds” in the prospectus supplement;

“— 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 ETF Underlying Supplement;

“— Risks Associated with non-U.S. companies” in ETF Underlying Supplement;

“— 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 ETF Underlying Supplement;

“— The Notes are Subject to Currency Exchange Risk” in ETF Underlying Supplement; and

“— There are Risks Associated with Emerging Markets” in ETF Underlying Supplement.

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

§ You may lose your entire initial investment. The securities do not guarantee any return of principal. The securities differ from ordinary debt securities in that the issuer will not necessarily pay the full principal amount of the securities at maturity. HSBC will only pay you the principal amount of your notes in cash if the securities have not been automatically redeemed prior to maturity and the final share price is greater than or equal to the downside threshold level. If the final share price is less than the downside threshold level, you will be exposed to the decline in the closing price of the underlying shares, as compared to the initial share price, on a 1 to 1 basis and you will receive an amount which will be less than 75% of the stated principal amount of the securities and which could be zero. As a result, you may lose up to 100% of the stated principal amount of the securities.

§ You will not receive any contingent quarterly payment for any quarterly period where the determination closing price is less than the downside threshold level on the related determination date. A contingent quarterly payment will be made with respect to a quarterly period only if the determination closing price is greater than or equal to the downside threshold level on the related determination date. If the determination closing price remains below the downside threshold level on each determination date over the term of the securities, you will not receive any contingent quarterly payments.

§ Your return on the securities is limited to the principal amount plus any contingent quarterly payments, regardless of any appreciation in the value of the underlying shares. Unless the final share price is less than the downside threshold level, you will receive at maturity the stated principal amount plus the contingent quarterly coupon payment with respect to the final determination date, regardless of any appreciation in the value of the underlying shares, which may be significant. The return on the securities will be limited to the contingent quarterly payment that is paid with respect to each determination date on which the determination closing price or the final share price, as applicable, is greater than or equal to the downside threshold level. It is possible that the closing price of the underlying shares could be below the downside threshold level on most or all of the determination dates so that you will receive little or no contingent quarterly payments. Accordingly, the return on the securities may be significantly less than the return on a direct investment in the underlying shares during the term of the securities.

§ The securities may be called prior to the maturity date.If the securities are called early, the holding period over which you will receive contingent quarterly payments could be as little as three months. There is no guarantee that

Based on the Performance of the iShares^® MSCI Emerging Markets Index Fund

you would be able to reinvest the proceeds from an investment in the securities at a comparable return for a similar level of risk following our exercise of the call provision.

§ The market price will be influenced by many unpredictable factors. Several factors will influence the value of the securities in the secondary market and the price at which HSBC Securities (USA) Inc. may be willing to purchase or sell the securities in the secondary market, including: the value, volatility and dividend yield of the underlying shares, whether the determination closing price has been below the downside threshold level on any determination date, interest and yield rates, time remaining to maturity, geopolitical conditions and economic, financial, political and regulatory or judicial events that affect the underlying shares and which may affect the final share price, the occurrence of certain events affecting the underlying shares that may or may not require an adjustment to the final share price and any actual or anticipated changes in our credit ratings or credit spreads. The price of the underlying shares may be, and has recently been, volatile, and we can give you no assurance that the volatility will lessen. You may receive less, and possibly significantly less, than the stated principal amount per security if you sell your securities prior to maturity.

§ 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 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 be listed on any securities exchange and secondary trading may be limited. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. HSBC Securities (USA) Inc. may, but is not obligated to, make a market in the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Because we do not expect that other broker-dealers will participate significantly in the 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 transact. If, at any time, HSBC Securities (USA) Inc. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

§ Certain built-in costs are likely to adversely affect the value of the securities prior to maturity. The original issue price of the securities includes the agent’s fees and commissions 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 stated 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.

§ Hedging and trading activity by our affiliates could potentially affect the value of the securities. One or more of our affiliates have carried out and will continue to carry out hedging activities related to the securities (and possibly to other instruments linked to the underlying shares), including trading in the underlying shares. Some of our affiliates also trade the underlying shares and other financial instruments related to the underlying shares on a regular basis as part of their general broker-dealer and other businesses. Any of these hedging or trading activities on or prior to the pricing date could potentially have increased the initial share price and, as a result, the downside threshold level which is the price at or above which the underlying shares must close on each determination date in order for you to earn a contingent quarterly payment or, if the securities are not called prior to maturity, in order for you to avoid being exposed to the negative price performance of the underlying shares at maturity. Additionally, such hedging or trading activities during the term of the securities could adversely affect the price of the underlying shares on the determination dates and, accordingly, whether the securities are automatically called prior to maturity and, if the securities are not called prior to maturity, the payout to you at maturity.

§ The calculation agent, which is HSBC or one of its affiliates, will make determinations with respect to the securities. As calculation agent, HSBC or one of its affiliates has determined the initial share price and the downside threshold level and will determine the final share price, whether the contingent quarterly payment will be

March 2012 Page 10

paid on each contingent payment date, whether the securities will be redeemed following any determination date, whether a market disruption event has occurred, whether to make any adjustments to any determination closing price or the final share price and the payment that you will receive upon an automatic early redemption or at maturity, if any. Determinations made by HSBC or one of its affiliates in its capacity as calculation agent, including with respect to the occurrence or non-occurrence of market disruption events, may adversely affect the payout to you upon an automatic early redemption or at maturity.

§ 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 amount due on the securities.

§ The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority as to the proper treatment of the securities for U.S. federal income tax purposes, and our counsel has not rendered an opinion as to their proper tax treatment.

Please read the discussion under “Fact Sheet – General Information – Tax considerations” in this document concerning the U.S. federal income tax consequences of an investment in the securities. Pursuant to the terms of the securities, you agree to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a contingent quarterly payment that will be treated as gross income to you at the time received or accrued in accordance with your regular method of tax accounting. If the IRS were successful in asserting an alternative treatment for the securities, the timing and character of income or loss on the securities might differ significantly from the tax treatment described herein. Non-U.S. Holders should note that we currently intend to withhold on any contingent quarterly payment paid to Non-U.S. Holders and will not be required to pay any additional amounts with respect to amounts withheld. We do not plan to request a ruling from the IRS regarding the tax treatment of the securities, and the IRS or a court may not agree with the tax treatment described herein.

On December 7, 2007, the Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. While it is not clear whether the securities would be viewed as similar to the prepaid forward contracts described in the notice, it is possible that any Treasury regulations or other guidance issued after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. The notice focuses on a number of issues, the most relevant of which for holders of the securities are the character and timing of income or loss and the degree, if any, to which income realized by non-U.S. investors should be subject to withholding tax. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, the issues presented by this notice and any tax consequences arising under the laws of any state, local or foreign taxing jurisdictions.
