Autocallable Market-Linked Step Up Notes

Summary

The Autocallable Market-Linked Step Up Notes Linked to the S&P 500^® Index, due September 25, 2020 (the “notes”) are our senior unsecured debt securities and are not a direct or indirect obligation of any third party. The notes are not deposit liabilities or other obligations of a bank and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other governmental agency of the United States or any other jurisdiction. The notes will rank equally with all of our other senior unsecured debt. Any payments due on the notes, including any repayment of principal, depend on the credit risk of HSBC and its ability to satisfy its obligations as they come due. The notes will be automatically called at the applicable Call Amount if the Observation Level of the Index, which is the S&P 500^® Index (the “Index”), is equal to or greater than the Call Level on the relevant Observation Date. If not called, at maturity, the notes provide you with a Step Up Payment if the Ending Value of the Index is equal to or greater than the Starting Value, but is not greater than the Step Up Value. If the Ending Value is greater than the Step Up Value, you will participate on a 1-for-1 basis in the increase in the level of the Index above the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

The estimated initial value of the notes is less than the price you pay to purchase the notes. The estimated initial value was determined by reference to our or our affiliates’ internal pricing models and reflects our internal funding rate, which is the borrowing rate we pay to issue market-linked notes, and the market prices for hedging arrangements related to the notes (which may include call options, put options or other derivatives). This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. The difference in the borrowing rate, as well as the underwriting discount and the costs associated with hedging the notes, including the hedging related charge described below, reduced the economic terms of the notes (including the Call Premiums and Call Amounts). The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes.

Hypothetical Payout Profile at Maturity

These hypothetical values show a payout profile at maturity, which would only apply if the notes are not called on any Observation Date.

Autocallable Market-Linked Step Up Notes   This graph reflects the returns on the notes, based on the Threshold Value of 100% of the Starting Value, the Step Up Payment of $2.10 per unit and the Step Up Value of 121% of the Starting Value. The green line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the stocks included in the Index, excluding dividends.   This graph has been prepared for purposes of illustration only.

Hypothetical Payments at Maturity

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes, assuming the notes are not called on any Observation Date. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value, Threshold Value, Ending Value, Step Up Value, whether the notes are called on an Observation Date, and term of your investment.

The following table is based on a Starting Value of 100, a Threshold Value of 100, the Step Up Value of 121 and the Step Up Payment of $2.10 per unit. It illustrates the effect of a range of Ending Values on the Redemption Amount per unit of the notes and the total rate of return to holders of the notes. The following examples do not take into account any tax consequences from investing in the notes.

Ending Value	Percentage Change from the Starting Value to the Ending Value	Redemption Amount per Unit	Total Rate of Return on the Notes
0.00	-100.00%	$0.00	-100.00%

150.00	50.00%	$15.00	50.00%
160.00	60.00%	$16.00	60.00%

(1) The hypothetical Starting Value of 100 used in these examples has been chosen for illustrative purposes only. The actual Starting Value is 2,495.62, which was the closing level of the Index on the pricing date.

(2) This is the hypothetical Threshold Value.

(3) This amount represents the sum of the principal amount and the Step Up Payment of $2.10.

(4) This is the hypothetical Step Up Value.

For recent actual levels of the Index, see “The Index” section below. The Index is a price return index and as such the Ending Value will not include any income generated by dividends paid on the stocks included in the Index, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

Risk Factors

We urge you to read the section “Risk Factors” in the product supplement and in the accompanying prospectus supplement. Investing in the notes is not equivalent to investing directly in the stocks included in the Index. You should understand the risks of investing in the notes and should reach an investment decision only after careful consideration, with your advisers, with respect to the notes in light of your particular financial and other circumstances and the information set forth in this term sheet and the accompanying product supplement, prospectus supplement and prospectus.

In addition to the risks in the product supplement identified below, you should review “Risk Factors” in the accompanying prospectus supplement, including the explanation of risks relating to the notes described in the section “— Risks Relating to All Note Issuances.”

§ If the notes are not automatically called, depending on the performance of the Index as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

§ Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

§ Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

§ If the notes are called, your investment return is limited to the return represented by the applicable Call Premium.

§ Your investment return may be less than a comparable investment directly in the stocks included in the Index.

§ The estimated initial value of the notes is less than the public offering price and may differ from the market value of the notes in the secondary market, if any. We determined the estimated initial value 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. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. Different pricing models and assumptions could provide valuations for the notes that are different from our estimated initial value. The estimated initial value reflects our internal funding rate we use to issue market-linked notes, as well as the mid-market value of the hedging arrangements related to the notes (which may include call options, put options or other derivatives).

§ Our internal funding rate for the issuance of these notes is lower than the rate we would use when we issue conventional fixed or floating rate debt securities. This is one of the factors that may result in the market value of the notes being less than their estimated initial value. 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 notes may be lower if it were based on the levels at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the notes to be more favorable to you.

§ The price of your notes in the secondary market, if any, immediately after the pricing date will be less than the public offering price. The public offering price takes into account certain costs, principally the underwriting discount, the hedging costs described on page TS-13 and the costs associated with issuing the notes. The costs associated with issuing the notes will be used or retained by us or one of our affiliates. If you were to sell your notes in the secondary market, if any, the price you would receive for your notes may be less than the price you paid for them.

§ The estimated initial value does not represent a minimum price at which we, MLPF&S or any of our respective affiliates would be willing to purchase your notes in the secondary market (if any exists) at any time. The price of your notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the level of the Index and changes in market conditions, and cannot be predicted with accuracy. The notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the notes to maturity. Any sale of the notes prior to maturity could result in a loss to you.

§ A trading market is not expected to develop for the notes. Neither we nor MLPF&S is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

§ Our business, hedging and trading activities, and those of MLPF&S and our respective affiliates (including trades in shares of companies included in the Index), and any hedging and trading activities we, MLPF&S or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

§ The Index sponsor may adjust the Index in a way that affects its level, and has no obligation to consider your interests.

§ You will have no rights of a holder, of the securities represented by the Index, and you will not be entitled to receive securities or dividends or other distributions by issuers of those securities.

§ Except to the extent that the common stock of Bank of America Corporation (the parent company of MLPF&S) is included in the Index, we, MLPF&S and our respective affiliates do not control any company included in the Index, and have not verified any disclosure made by any other company.

The Index

We have derived all information relating to the Index including, without limitation, its make-up, performance, method of calculation and changes in its components, from publicly available sources.  That information reflects the policies of and is subject to change by S&P Dow Jones Indices LLP (the “Index sponsor”). The Index sponsor is under no obligation to continue to publish, and may discontinue or suspend the publication of the Index at any time.

The Index Sponsor Publishes the Index

The Index is intended to provide an indication of the pattern of common stock price movement.  The calculation of the level of the Index, discussed below in further detail, is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 500 companies as of a particular time compared to the aggregate average Market Value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.  The Index sponsor chooses companies for inclusion in the Index with the aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the Standard & Poor’s Stock Guide Database, which the Index sponsor uses as an assumed model for the composition of the total market.  The Index sponsor may from time to time in its sole discretion, add companies to or delete companies from, the Index to achieve these objectives.

Relevant criteria employed by the Index sponsor include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the market price of that company’s common stock is generally responsive to changes in the affairs of the respective industry and the market value and trading activity of the common stock of that company.  Eleven main industry groups comprise the Index:  Information Technology, Financials, Consumer Staples, Health Care, Energy, Industrials, Consumer Discretionary, Utilities, Real Estate, Materials and Telecommunication Services.  Changes in the Index are reported daily in the financial pages of many major newspapers, on Bloomberg Professional^® service under the symbol “SPX” and on the Index sponsor’s website.  Information contained in the Index sponsor’s website is not incorporated by reference in, and should not be considered a part of, this document.

The Index does not reflect the payment of dividends on the stocks included in the Index and therefore the payment on the notes will not produce the same return you would receive if you were able to purchase such underlying stocks and hold them until the maturity date or earlier call.

Computation of the Index

Prior to March 2005, the Market Value of a component stock was calculated as the product of the market price per share and the total number of outstanding shares of the component stock.  In March 2004, the Index sponsor announced that it would transition the Index to float adjusted market capitalization weights.  The transition began in March 2005 and was completed in September 2005.  The Index sponsor’s criteria for selecting stocks for the Index were not changed by the shift to float adjustment.  However, the adjustment affects each company’s weight in the Index (i.e., its Market Value).  Currently, the Index sponsor calculates the Index based on the total float-adjusted market capitalization of each component stock, where each stock’s weight in the Index is proportional to its float-adjusted Market Value.

Under float adjustment, the share counts used in calculating the Index reflect only those shares that are available to investors, not all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock’s outstanding shares, other than holdings by “block owners,” were removed from the float for purposes of calculating the Index. Generally, these “control holders” will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float.  Shares held in trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares, are normally part of the float unless those shares form a control block. If a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class are treated as a control block.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares by the total shares outstanding. As of September 21, 2012, available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company’s officers and directors hold 3% of the company’s shares, and no other control group holds 5% of the company’s shares, the Index sponsor would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company’s officers and directors hold 3% of the company’s shares and another control group holds 20% of the company’s shares, the Index sponsor would assign an IWF of 0.77, reflecting the fact that 23% of the company’s outstanding shares are considered to be held for control. For companies with multiple classes of stock,

Autocallable Market-Linked Step Up Notes TS-9

Autocallable Market-Linked Step Up Notes
Linked to the S&P 500^® Index, due September 25, 2020

the Index sponsor calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

As of the date of this term sheet, the Index is also calculated using a base-weighted aggregate methodology:  the level of the Index reflects the total Market Value of all the component stocks relative to the Index base period of 1941-43.  The daily calculation of the Index is computed by dividing the Market Value of the Index component stocks by a Divisor, which is adjusted from time to time as discussed below.

The simplest capitalization weighted index can be thought of as a portfolio consisting of all available shares of the stocks in the index.  While this might track this portfolio’s value in dollar terms, it would probably yield an unwieldy number in the trillions.  Therefore, the actual number used in the Index is scaled to a more easily handled number, currently in the thousands, by dividing the portfolio Market Value by the Divisor.

Ongoing maintenance of the Index includes monitoring and completing the adjustments for additions and deletions of the constituent companies, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spin-offs.  Continuity in the level of the Index is maintained by adjusting the Divisor for all changes in the Index constituents’ share capital after the base period of 1941-43 with the level of the Index as of the base period set at 10.  Some corporate actions, such as stock splits and stock dividends do not require Divisor adjustments because following a stock split or stock dividend, both the stock price and number of shares outstanding are adjusted by the Index sponsor so that there is no change in the Market Value of the component stock.  All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

To prevent the level of the Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the Index also require a Divisor adjustment.  By adjusting the Divisor for the change in total Market Value, the level of the Index remains constant.  This helps maintain the level of the Index as an accurate barometer of stock market performance and ensures that the movement of the Index does not reflect the corporate actions of individual companies in the Index.  All Divisor adjustments are made after the close of trading and after the calculation of the closing levels of the Index.  As noted in the preceding paragraph, some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the Index and do not require Divisor adjustments. The table below summarizes the types of Index maintenance adjustments and indicates whether or not a Divisor adjustment is required.

Type of Corporate Action	Comments	Divisor Adjustment
Company added/deleted	Net change in Market Value determines Divisor adjustment.	Yes
Change in shares outstanding	Any combination of secondary issuance, share repurchase or buy back—share counts revised to reflect change.	Yes
Stock split	Share count revised to reflect new count.  Divisor adjustment is not required since the share count and price changes are offsetting.	No
Spin-off	If spun-off company is not being added to the Index, the Divisor adjustment reflects the decline in Index Market Value (i.e., the value of the spun-off unit).	Yes
Spin-off	Spun-off company added to the Index, no company removed from the Index. As a general policy, a spin off company is added to the Index if the parent company is an Index constituent, at a zero price at the market close of the day before the ex-date (with no divisor adjustment). The spin off security will remain in the Index if it meets all necessary criteria.	No
Spin-off	Spun-off company added to the Index, another company removed to keep number of names	Yes

	fixed. Divisor adjustment reflects deletion.
Change in IWF	Increasing (decreasing) the IWF increases (decreases) the total Market Value of the Index. The Divisor change reflects the change in Market Value caused by the change to an IWF.	Yes
Special dividend	When a company pays a special dividend the share price is assumed to drop by the amount of the dividend; the Divisor adjustment reflects this drop in Index Market Value.	Yes
Rights offering	Each shareholder receives the right to buy a proportional number of additional shares at a set (often discounted) price.  The calculation assumes that the offering is fully subscribed.  Divisor adjustment reflects increase in market cap measured as the shares issued multiplied by the price paid.	Yes

Each of the corporate events exemplified in the table requiring an adjustment to the Divisor has the effect of altering the Market Value of the component stock and consequently of altering the aggregate Market Value of the Index component stocks (the “Post-Event Aggregate Market Value”).  In order that the level of the Index (the “Pre-Event Index Value”) not be affected by the altered Market Value (whether increase or decrease) of the affected component stock, a new Divisor (“New Divisor”) is derived as follows:

Post-Event Aggregate Market Value	=	Pre-Event Index Value
New Divisor
New Divisor	=	Post-Event Aggregate Market Value
		Pre-Event Index Value

Another large part of the Index maintenance process involves tracking the changes in the number of shares outstanding of each of the companies whose stocks are included in the Index.  To prevent the level of the Index from changing due to corporate actions, corporate actions which affect the total Market Value of the Index require a Divisor adjustment. By adjusting the Divisor for the change in Market Value, the level of the Index remains constant and does not reflect the corporate actions of individual companies in the Index. Divisor adjustments are made after the close of trading and after the calculation of the Index closing level.

Changes in a company’s shares outstanding of 5.00% or more due to public offerings are made as soon as reasonably possible. Share changes due to mergers or acquisitions of publicly held companies that trade on a major exchange are implemented when the transaction occurs, even if both of the companies are not in the same headline index, and regardless of the size of the change. All other changes of 5.00% or more (due to, for example, tender offers, Dutch auctions, voluntary exchange offers, company stock repurchases, private placements, acquisitions of private companies or non-index companies that do not trade on a major exchange, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participations, at-the-market stock offerings or other recapitalizations) are made weekly, and are announced on Fridays for implementation after the close of trading on the following Friday.

Changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September and December, and are usually announced two to five days prior.

If a change in a company’s shares outstanding of 5.00% or more causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case-by-case basis.

Supplement to the Plan of Distribution

We will deliver the notes against payment therefor in New York, New York on a date that is greater than two business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than two business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S acting as a principal in effecting the transaction for your account.

MLPF&S may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these will include MLPF&S’s trading commissions and mark-ups. MLPF&S may act as principal or agent in these market-making transactions; however, it is not obligated to engage in any such transactions. At MLPF&S’s discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the estimated initial value of the notes. Any price offered by MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Index, the remaining term of the notes, and the issuer’s creditworthiness. However, neither we nor any of our affiliates is obligated to purchase your notes at any price, or at any time, and we cannot assure you that we, MLPF&S or any of our respective affiliates will purchase your notes at a price that equals or exceeds the estimated initial value of the notes.

The value of the notes shown on your account statement provided by MLPF&S will be based on their estimate of the value of the notes if MLPF&S or one of its affiliates were to make a market in the notes, which it is not obligated to do. This estimate will be based upon the price that MLPF&S may pay for the notes in light of then-prevailing market conditions, and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the estimated initial value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding HSBC or for any purpose other than that described in the immediately preceding sentence.

Role of MLPF&S

MLPF&S will participate as selling agent in the distribution of the notes. Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the performance of the Index and the $10 per unit principal amount. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with MLPF&S or one of its affiliates. The terms of these hedging arrangements are determined by MLPF&S seeking bids from market participants, which could include one of our affiliates and MLPF&S and its affiliates. These hedging arrangements take into account a number of factors, including the issuer’s creditworthiness, interest rate movements, the volatility of the Index, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes depend in part on the terms of the hedging arrangements.

MLPF&S has advised us that the hedging arrangements will include a hedging related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to MLPF&S from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by MLPF&S or any third party hedge providers.

Summary Tax Consequences

You should consider the U.S. federal income tax consequences of an investment in the notes, including the following:

§ There is no statutory, judicial, or administrative authority directly addressing the characterization of the notes.

§ You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the notes for all tax purposes as pre-paid executory contracts with respect to the Index.

§ Under this characterization and tax treatment of the notes, a U.S. holder (as defined in the prospectus supplement) generally will recognize capital gain or loss upon maturity or upon a sale or exchange of the notes prior to maturity. This capital gain or loss generally will be long-term capital gain or loss if you held the notes for more than one year.

§ No assurance can be given that the IRS or any court will agree with this characterization and tax treatment.

§ Under current Internal Revenue Service guidance, withholding on “dividend equivalent” payments (as discussed in the product supplement and prospectus supplement), if any, will not apply to notes that are issued as of the date of this pricing supplement unless such notes are “delta-one” instruments. Additionally, the IRS has announced that withholding under the Foreign Account Tax Compliance Act (as discussed in the prospectus supplement) on payments of gross proceeds from a sale or redemption of the notes will only apply to payments made after December 31, 2018.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws. You should review carefully the discussion under the section entitled “U.S. Federal Income Tax Summary” beginning on page PS-32 of product supplement EQUITY INDICES SUN-1.

This opinion is given as of the date hereof and is limited to the laws of the State of New York, the Maryland General Corporation Law (including the statutory provisions, all applicable provisions of the Maryland Constitution and the reported judicial decisions interpreting the foregoing) and the federal laws of the United States of America. This opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the Senior Indenture and the genuineness of signatures and to such counsel’s reliance on the issuer and other sources as to certain factual matters, all as stated in the legal opinion dated March 5, 2015, which has been filed as Exhibit 5.3 to the issuer’s registration statement on Form S-3 dated March 5, 2015.

Market-Linked Investments Classification

 

MLPF&S classifies certain market-linked investments (the “Market-Linked Investments”) into categories, each with different investment characteristics. The following description is meant solely for informational purposes and is not intended to represent any particular Enhanced Return Market-Linked Investment or guarantee any performance.

Enhanced Return Market-Linked Investments are short- to medium-term investments that offer you a way to enhance exposure to a particular market view without taking on a similarly enhanced level of market downside risk. They can be especially effective in a flat to moderately positive market (or, in the case of bearish investments, a flat to moderately negative market). In exchange for the potential to receive better-than market returns on the linked asset, you must generally accept market downside risk and capped upside potential. As these investments are not market downside protected, and do not assure full repayment of principal at maturity, you need to be prepared for the possibility that you may lose all or part of your investment.
