HSBC USA Inc.

Contingent Coupon Buffered Securities with

Trigger Upside and Downside Participation

Indicative Terms(1)
Principal Amount	$1,000 per security
Term	Approximately [4.25 years to 4.75 years], to be determined on the Trade Date.
Reference Asset	The S&P 500® Index (Ticker: SPX)
Contingent Coupon Rate	0.3333% per month (4.00% per annum), payable monthly with respect to each Contingent Coupon Observation Period on the related Coupon Payment Date as long as a Knock-Out Event does not occur.
Contingent Coupon Payment	$3.333 per month, if payable
Contingent Coupon	If a Knock-Out Event has not occurred during or prior to a Contingent Coupon Observation Period: you will receive the Contingent Coupon Payment applicable to that period. If a Knock-Out Event has occurred during any Contingent Coupon Observation Period: you will not receive the Contingent Coupon Payment applicable to that period and all subsequent Contingent Coupon Observation Periods. In this event, no further Contingent Coupon Payments will be payable in connection with the securities.
Coupon Trigger	80% of the Initial Level
Buffer Level	-20%
Participation Rate	1.25x
Knock-Out Event	A Knock-Out Event shall occur if, on any Scheduled Trading Day, the Official Closing Level of the Reference Asset is less than its Coupon Trigger
Reference Return	Final Level – Initial Level           Initial Level
Payment at Maturity per Security	If a Knock-Out Event has not occurred: $1,000 (zero return) If a Knock-Out Event has occurred: $1,000 × (1+ [Reference Return + 20%] × Participation Rate). This amount will be greater than the principal amount if the Reference Return is greater than -20%. However, if the Reference Return is less than -20%, you will lose a portion of the principal amount. Under these circumstances, you will lose 1.25% of the Principal Amount for each percentage point that the Reference Return is less than the Buffer Level. For example, if the Reference Return is -21%, you will suffer a 1.25% loss and receive 98.75% of the Principal Amount at maturity, subject to the credit risk of HSBC. If the Reference Return is less than the Buffer Level, you will lose up to 100% of your investment, excluding any Contingent Coupon Payments paid on the securities.

The Securities

The securities are designed for investors who believe the Reference Asset will not significantly depreciate over the term of the securities. If the Official Closing Level of the Reference Asset does not fall below its Coupon Trigger on any Scheduled Trading Date, and thus a Knock-Out Event does not occur, you will receive a payment at maturity equal to the Principal Amount plus the final Contingent Coupon Payment. If a Knock-Out Event occurs, you will not receive the Contingent Coupon Payment relating to that Contingent Coupon Observation Period, and no further Contingent Coupon Payments will be payable in connection with the securities.

If a Knock-Out Event has occurred during the term of the securities, you will receive, at maturity, a payment equal to the Principal Amount plus the Principal Amount multiplied by the sum of one plus the Reference Return plus 20%, multiplied by the Participation Rate. If, at maturity, the Reference Return is greater than -20%, this amount will be greater than the principal amount. If, at maturity, the Reference Return is less than the Buffer Level, then the securities are subject to 1.25x exposure to any potential decline of the Reference Asset beyond the Buffer Level of -20%, excluding any Contingent Coupon Payments that have been paid on the securities.

The offering period for the securities is through March 23, 2017

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 a Knock-Out Event has not occurred during or prior to the term of the securities, you will receive $1,000 per $1,000 Principal Amount (zero return), plus the final Contingent Coupon Payment.

If a Knock-Out Event occurs during the term of the securities, you will receive a cash payment on the Maturity Date, per $1,000 Principal Amount, calculated as follows:

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

This amount will be greater than the principal amount if the Reference Return is greater than -20%.

However, if the Reference Return is less than -20%, you will lose a portion of the principal amount. Under these circumstances, you will lose 1.25% of the Principal Amount for each percentage point that the Reference Return is less than the Buffer Level. For example, if the Reference Return is -21%, you will suffer a 1.25% loss and receive 98.75% of the Principal Amount at maturity, subject to the credit risk of HSBC. If the Reference Return is less than the Buffer Level, you will lose up to 100% of your investment, excluding any Contingent Coupon Payments paid on the securities.

Contingent Coupon

If a Knock-Out Event has not occurred during a Contingent Coupon Observation Period: you will receive the Contingent Coupon Payment applicable to that period.

If a Knock-Out Event has occurred during any Contingent Coupon Observation Period: you will not receive the Contingent Coupon Payment applicable to that period and all subsequent Contingent Coupon Observation Periods. In this event, no further Contingent Coupon Payments will be payable in connection with the securities.

Calculation Agent

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

Reference Sponsor

INVESTOR SUITABILITY

The securities may be suitable for you if:

4 You seek an investment with a return linked to the potential positive performance of the Reference Asset and you believe the level of the Reference Asset will not significantly decrease over the term of the securities.

4 You are willing to make an investment that is exposed to the downside Participation Rate of 1.25x for each percentage point that the Reference Return is less than -20% and you understand that the downside Participation Rate may magnify your losses up to a 100% loss of your investment.

4 You seek a monthly Contingent Coupon Payment based on the performance of the Reference Asset in the related Contingent Coupon Observation Period, which will be paid at the Contingent Coupon Rate if the Official Closing Level of the Reference Asset is greater than or equal to its Coupon Trigger on each Scheduled Trading Day during the applicable and each previous Contingent Coupon Observation Period.

4 You are willing to invest in securities, the return on which will be limited to the Contingent Coupon Payments if a Knock-Out Event does not occur.

4 You are willing to hold the securities to maturity.

4 You are comfortable with the creditworthiness of HSBC, as Issuer of the securities.

4 You believe that the Contingent Coupon Payments, if any, will not provide you with your desired return.

4 You are unwilling to accept that the return on the Notes will be limited to the Contingent Coupons, if any, if a Knock-Out Event does not occur or you seek an investment that provides a guaranteed opportunity to participate in the positive performance of the Reference Asset.

4 You seek an investment that provides full return of principal.

4 You prefer to receive the dividends or other distributions paid on the stocks included in the Reference Asset.

4 You prefer the lower risk, and therefore accept the potentially lower returns, of conventional debt securities with comparable maturities issued by HSBC or another issuer with a similar credit rating.

FWP-9

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page S-2 of the accompanying Equity Index Underlying Supplement. Investing in the securities is not equivalent to investing directly in any of the stocks included in the Reference Asset. 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 prospectus, prospectus supplement and Equity Index Underlying Supplement.

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

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

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

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

Your investment in the securities may result in a loss.

You will be exposed on a leveraged basis to any decline in the Final Level from the Initial Level beyond the Buffer Level of -20%, which will magnify your losses up to a 100% loss of your investment. Accordingly, if the Reference Return is less than -20%, your Payment at Maturity will be less than the Principal Amount of your securities. You will lose up to 100% of your investment at maturity if the Reference Return is less than the Buffer Level, excluding any Contingent Coupon Payments paid during the term of the securities.

You may not receive any Contingent Coupon Payments.

We will not necessarily make monthly Contingent Coupon Payments on the securities. If the Official Closing Level of the Reference Asset on a Scheduled Trading Day during a Contingent Coupon Observation Period is less than its Coupon Trigger, you will not receive the related Contingent Coupon Payment or any further Contingent Coupon Payments in connection with the securities. Especially if a Knock-Out Event occurs early in the term of the securities, the Contingent Coupon Payments on the securities may be negligible.

You are exposed to the market risk of the Reference Asset, with respect to both the Contingent Coupons, if any, and the payment at maturity.

To receive each Contingent Coupon Payment, the Reference Asset must close at or above the Coupon Trigger on each Scheduled Trading Day during the related and each previous Contingent Coupon Observation Period. In addition, if a Knock-Out Event has occurred during the term of the securities, you will be fully exposed to the decrease in the Reference Asset on a 1.25x leveraged basis beyond the Buffer Level of -20%. Under this scenario, the payment at maturity may be less than the Principal Amount and you may lose up to 100% of your investment. Accordingly, your investment is subject to the market risk of the Reference Asset.

Excluding any final Contingent Coupon, the payment at maturity can only exceed the principal amount if a Knock-Out Event occurs.

If a Knock-Out Event does not occur during the term of the securities, the payment on the securities will be limited to the Contingent Coupon Payments, and you will not participate in any positive return of the Reference Asset. You will only receive a payment at maturity that exceeds the principal amount (excluding any final Contingent Coupon Payment) if a Knock-Out Event occurs and the Reference Return is greater than -20%. However, if a Knock-Out Event occurs, any payment at maturity in excess of the principal amount may be limited, as the level of the Reference Asset will need to increase after the Knock-Out Event to at least 80% of the Initial Level in order for you to receive an amount that equals or exceeds the principal amount.

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 Contingent Coupon Payments and the 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.

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

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

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

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

The Estimated Initial Value of the securities, which will be determined by us on the Pricing Date, will be less than the price to public and may differ from the market value of the securities in the secondary market, if any.

The Estimated Initial Value of the securities will be calculated by us on the Pricing Date and will be less than the price to public. The Estimated Initial Value will reflect our internal funding rate, which is the borrowing rate we pay to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the securities. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the securities may be lower if it were based on the prices at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the securities to be more favorable to you. We will determine the value of the embedded derivatives in the securities by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the securities that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your securities in the secondary market (if any exists) at any time.

The price of your securities in the secondary market, if any, immediately after the Pricing Date will be less than the price to public.

The price to public takes into account certain costs. These costs, which will be used or retained by us or one of our affiliates, include the underwriting discount, our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the securities and the costs associated with structuring and hedging our obligations under the securities. If you were to sell your securities in the secondary market, if any, the price you would receive for your securities may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your securities in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Reference Asset and changes in market conditions, and cannot be predicted with accuracy. The securities are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the securities to maturity. Any sale of the securities prior to maturity could result in a loss to you.

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

Assuming that all relevant factors remain constant after the Original Issue Date, the price at which HSBC Securities (USA) Inc. may initially buy or sell the securities in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed the Estimated Initial Value on the Pricing Date for a temporary period expected to be approximately 12 months after the Original Issue Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the securities and other costs in connection with the securities that we will no longer expect to incur over the term of the securities. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the securities and any agreement we may have with the distributors of the securities. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the securities based on changes in market conditions and other factors that cannot be predicted.

The securities lack liquidity.

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

Potential conflicts of interest may exist.

HSBC and its affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and our other affiliates 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 and the discussion under “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 level of the Reference Asset relative to its Initial Level. We cannot predict the Final Level. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events, and the hypothetical Initial Level used in the table and examples below is not expected to be the actual Initial Level of the Reference Asset. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset or the return on your securities. The Final Settlement Value may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including such a security issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the Payment at Maturity on a $1,000 investment in the securities for a hypothetical range of Reference Returns from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Securities” as used below is the number, expressed as a percentage, that results from comparing the Final Settlement Value per $1,000 Principal Amount to $1,000. The potential returns described here assume that a Knock-Out Event has occurred during the term of the securities and that your securities are held to maturity, and exclude any Contingent Coupon Payments paid on the securities. You should consider carefully whether the securities are suitable to your investment goals. The following table and examples assume the following:

4	Principal Amount:	$1,000
4	Hypothetical Initial Level:	2,000.00
4	Participation Rate (upside and downside):	1.25x
4	Buffer Level:	-20%

The actual Initial Level will be determined on the Pricing Date.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Payment at Maturity	Hypothetical Return on the Securities
4,000.00	100.00%	$2,500.00	150.00%

FWP-12

The following examples indicate how the Final Settlement Value would be calculated with respect to a hypothetical $1,000 investment in the securities, and exclude the effect of any Contingent Coupon Payments paid on the securities.

Example 1: The level of the Reference Asset increases from the Initial Level of 2,000.00 to a Final Level of 2,200.00 and a Knock-Out Event has not occurred during the term of the securities.

Reference Return:	10.00%
Final Settlement Value:	$1,000.00

Because a Knock-Out Event has not occurred during the term of the securities, the Final Settlement Value would be $1,000.00 per $1,000 Principal Amount. In that case, you will not participate in the appreciation of the Reference Asset.

Example 2: The level of the Reference Asset increases from the Initial Level of 2,000.00 to a Final Level of 2,400.00, and a Knock-Out Event has occurred during the term of the securities.

Reference Return:	20.00%
Final Settlement Value:	$1,500.00

Because a Knock-Out Event has occurred during the term of the securities, the Final Settlement Value would be $1,500.00 per $1,000 Principal Amount, calculated as follows:

= $1,000 × (1+ [Reference Return + 20.00%] × Participation Rate)

= $1,000 × (1+ [20.00% + 20.00%] × 1.25)

= $1,500.00

Example 2 shows that you have enhanced upside exposure if a Knock-Out Event has occurred during the term of the securities and the Reference Return is greater than the Buffer Level.

Example 3: The level of the Reference Asset decreases from the Initial Level of 2,000.00 to a Final Level of 1,800.00, and a Knock-Out Event has occurred during the term of the securities.

Reference Return:	-10.00%
Final Settlement Value:	$1,125.00

Because a Knock-Out Event has occurred during the term of the securities, the Final Settlement Value would be $1,125.00 per $1,000 Principal Amount, calculated as follows:

= $1,000 × (1+ [Reference Return + 20.00%] × Participation Rate)

= $1,000 × (1+ [-10.00% + 20.00%] × 1.25)

= $1,125.00

Example 3 shows that if a Knock-Out Event occurs, and the Final Level is less than the Initial Level, you will still receive a payment at maturity that exceeds the principal amount if the Reference Return is greater than -20%.

Example 4: The level of the Reference Asset decreases from the Initial Level of 2,000.00 to a Final Level of 1,400.00 and a Knock-Out Event has occurred during the term of the securities.

Reference Return:	-30.00%
Final Settlement Value:	$875.00

Because a Knock-Out Event has occurred during the term of the securities, the Final Settlement Value would be $875.00 per $1,000 Principal Amount, calculated as follows:

= $1,000 × (1+ [Reference Return + 20.00%] × Participation Rate)

= $1,000 × (1+ [-30.00% + 20.00%] × 1.25)

= $875.00

Example 4 shows that you are exposed on a 1.25x leveraged basis to declines in the level of the Least Performing Underlying beyond the Buffer Level of -20% if a Knock-Out Event has occurred during the term of the securities. YOU MAY LOSE UP TO 100% OF THE PRINCIPAL AMOUNT OF YOUR SECURITIES.

THE S&P 500® Index (“SPX”)

Description of the SPX The SPX is a capitalization-weighted index of 500 U.S. stocks. It is designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries. The top 5 industry groups by market capitalization as of February 28, 2017 were: Information Technology, Financials, Health Care, Consumer Discretionary and Industrials. For more information about the SPX, see “S&P 500® Index” on page S-44 of the accompanying Equity Index Underlying Supplement.

Historical Performance of the SPX The following graph sets forth the historical performance of the SPX based on the daily historical closing levels from January 1, 2008 through March 15, 2017. We obtained the closing levels below from the Bloomberg Professional® service. We have not undertaken any independent review of, or made any due diligence inquiry with respect to, the information obtained from the Bloomberg Professional® service.

The historical levels of the SPX should not be taken as an indication of future performance, and no assurance can be given as to the Official Closing Level of the SPX on the Final Valuation Date.

EVENTS OF DEFAULT AND ACCELERATION

If the securities have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the securities, the calculation agent will determine the accelerated payment due and payable at maturity in the same general manner as described in “Payment at Maturity” in this free writing prospectus. In that case, the Scheduled Trading Day immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the Reference Return, and the accelerated maturity date will be three business days after the accelerated Final Valuation Date. If a final Contingent Coupon Payment is due, the calculation agent may reduce it to reflect the shortened length of the relevant monthly Contingent Coupon Observation Period. If a Market Disruption Event exists with respect to the Reference Asset on that Scheduled Trading Day, then the accelerated Final Valuation Date for the Reference Asset will be postponed for up to five Scheduled Trading Days (in the same manner used for postponing the originally scheduled Final Valuation Date). The accelerated maturity date will also be postponed by an equal number of business days.

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

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

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

An affiliate of HSBC has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the securities.

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

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

FWP-15

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 contingent income-bearing pre-paid executory contract with respect to the Reference Asset. We intend to treat the securities consistent with this approach. Pursuant to the terms of the securities, you agree to treat the securities under this approach for all U.S. federal income tax purposes. Subject to the limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Morrison & Foerster LLP, it is reasonable to treat a security as a contingent income-bearing pre-paid executory contract with respect to the Reference Asset. Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the securities, other characterizations and treatments are possible and the timing and character of income in respect of the securities might differ from the treatment described herein. For example, the securities could be treated as debt instruments that are “contingent payment debt instruments” for U.S. federal income tax purposes subject to the treatment described under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes — Contingent Notes” in the accompanying prospectus supplement.

We will not attempt to ascertain whether any of the entities whose stock is included in the Reference Asset would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purposes. If one or more of the entities whose stock is included in the Reference Asset were 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 the Reference Asset and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in the Reference Asset is or becomes a PFIC or a USRPHC.

U.S. Holders. Please see the discussion under the heading “U.S. Federal Income Tax Considerations — Tax Treatment of U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated as Executory Contracts” in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to U.S. holders (as defined in the accompanying prospectus supplement). Pursuant to the approach discussed above, we intend to treat any gain or loss upon maturity or an earlier sale or exchange as capital gain or loss in an amount equal to the difference between the amount you receive at such time (other than with respect to a Contingent Coupon) and your tax basis in the security. Any such gain or loss will be long-term capital gain or loss if you have held the security for more than one year at such time for U.S. federal income tax purposes. Your tax basis in a security generally will equal your cost of the security. In addition, the tax treatment of the Contingent Coupons is unclear. Although the tax treatment of the Contingent Coupons is unclear, we intend to treat any Contingent Coupon, including on the Maturity Date, as ordinary income includible in income by you at the time it accrues or is received in accordance with your normal method of accounting for U.S. federal income tax purposes.

Non-U.S. Holders. Please see the discussion under the heading “U.S. Federal Income Tax Considerations—Tax Treatment of Non-U.S. Holders” in the accompanying prospectus supplement for further discussion of U.S. federal income tax considerations applicable to non-U.S. holders (as defined in the accompanying prospectus supplement). Because the U.S. federal income tax treatment (including the applicability of withholding) of the Contingent Coupons is uncertain, the entire amount of the Contingent Coupons will be subject to U.S. federal income tax withholding at a 30% rate (or at a lower rate under an applicable income tax treaty). We will not pay any additional amounts in respect of such withholding.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a non-U.S. holder. Under U.S. Treasury Department regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, the IRS has issued guidance that states that the U.S. Treasury Department and the IRS intend to amend the effective dates of the U.S. Treasury regulations to provide that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2018. Based on the Issuer’s determination that the securities are not “delta-one” instruments, non-U.S. holders should not be subject to withholding on dividend equivalent payments, if any, under the securities. However, it is possible that the securities could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Asset or the securities, and following such occurrence the securities could be treated as subject to withholding on dividend equivalent payments. Non-U.S. holders that enter, or have entered, into other transactions in respect of the References Asset or the securities should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the securities and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

FWP-16

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

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

PROSPECTIVE PURCHASERS OF SECURITIES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF SECURITIES.
