HSBC Buffered Accelerated Market Participation Securities™ Invest with Confidence

Invest with Confidence With the development of structured notes, today’s investors can now take control of their portfolio and gain exposure to markets like US or international equities, currencies, or commodities in a way that suits their specific risk profile. As complements or alternatives to traditional stock and bond holdings, structured notes can be designed to provide different levels of downside protection (subject to issuer’s credit risk), thus giving investors more confidence to stay engaged in the markets, or explore new ones. HSBC USA, Inc. (“HSBC”) offers a diverse array of structured notes, including Buffered Accelerated Market Participation Securities or “Buffered AMPS”. Buffered AMPS are an alternative to traditional long-only investing and may out-perform a direct investment in the underlying asset in a moderately positive return environment and in a negative return environment. They provide investors with a degree of downside protection (subject to the issuer’s credit risk) while also affording an opportunity for accelerated returns on the upside, subject to a maximum return. Buffered AMPS are typically linked to a broad based equity index but can also be linked to particular regions, sectors, or individual stocks*. Buffered AMPS: where do they fit? Investors often hold Buffered AMPS within the equity portion of their portfolio. That is, Buffered AMPS can be used alongside, or in place of, investments like index funds or ETFs to both gain the benefit of the buffer and pursue a return enhancement strategy.

Investor profile Buffered AMPS may be of interest to a broad range of investors, including but not limited to the following: Current or prospective holders of the underlying. Investors looking for a potential recovery strategy for underperforming assets. Investors who seek to out-perform a direct investment in the underlying asset for both moderately positive returns as well as negative returns. The Buffered AMPS may be attractive if: You believe the level of the underlying will increase, but not by more than the maximum return. You seek an investment that provides limited protection from a decline in the underyling. You are willing to hold the Buffered AMPS to maturity. You are comfortable with the creditworthiness of HSBC, as issuer of the Buffered AMPS. The Buffered AMPS may not be attractive if: You believe the underlying performance will be negative or not sufficiently positive to provide you with your desired return. You are unwilling to accept a capped return and be exposed to any negative underlying performance on a 1-to-1 basis if the underlying performance is less than the buffer. You prefer to receive dividends paid on the underlying or seek current income. You are not willing or are unable to assume the credit risk associated with HSBC, as issuer of the Buffered AMPS.

Risk factors An investment in the Buffered AMPS involves risks some of which are summarized below. Buffered AMPS are linked to the performance of a specific underlying asset and are not equivalent to investing directly in that asset. It is important to note that Buffered AMPS may not always reflect the actual performance of the underlying asset and have different risks than traditional debt securities. Like other investments, each individual issuance of Buffered AMPS should be carefully evaluated with respect to an individual investor’s financial objectives, suitability, tax considerations and other relevant factors. Prior to investing in an individual issuance of Buffered AMPS, you should carefully review the prospectus for that issuance which will include a fuller description of the risks related to investing in Buffered AMPS. Factors to consider before investing in the Buffered AMPS include: The investment may result in a loss. The return on the Buffered AMPS is linked to the performance of the underlying asset, which may be negative, and involves risks specific to the relevant underlying asset. The positive return, if any, is limited by the maximum return and may not reflect the full performance of the underlying asset. Payment, if any, is subject to the ability of HSBC to pay its obligations as they become due. Any payment on the Buffered AMPS is subject to the credit risk of HSBC. Investors will not receive any periodic interest payments, dividend payments or other distributions. Investors should consider their liquidity needs prior to purchasing Buffered AMPS as there may be little or no secondary market for the Buffered AMPS and they will not be listed or displayed on any securities exchange. Certain built-in costs are likely to adversely affect the value of the Buffered AMPS if sold prior to maturity. Therefore the Buffered AMPS should be viewed as instruments to be held for the full term of the Note. There is a potential conflict of interest in that HSBC or its affiliates will play a variety of roles, including acting as calculation agent and hedge provider for HSBC’s obligations under the Buffered AMPS. The Buffered AMPS may provide a yield to maturity that is less than that of a standard debt security of comparable maturity issued by HSBC or any other issuer. The Buffered AMPS are not deposits of HSBC or any of its affiliates; they are not insured by the FDIC or any other federal or state government agency of the United States or any other jurisdiction.
