What investment objectives do the Buffered Uncapped Notes fulfill? ·  The Buffered Uncapped Notes may be useful for investors who seek an investment with a return linked to the relevant Reference Asset but also seek to protect a portion of their investment from downside risk at maturity. ·  The Notes provide the potential for uncapped investment growth with a defined level of downside protection. This downside protection, also known as a “Buffer”, “Buffer Level” or “Buffer Percentage” provides a predefined range of loss protection at maturity, subject to the credit risk of HSBC. ·  These Notes provide at least 100% upside participation (referred to as the Upside Participation Rate) in any positive return of the Reference Asset, typically an equity index or exchange-traded fund (an “ETF”), measured from the Pricing Date to the Final Valuation Date.

How do the Buffered Uncapped Notes work? ·  These investments offer two important features: (1) an Upside Participation Rate of at least 100%, in any positive performance of an equity index or ETF with no maximum return cap and (2) limited downside protection in the form of a pre-determined Buffer at maturity. ·  At maturity, there are three possible scenarios based on the performance of the Reference Asset: o  Scenario 1: The return of the Reference Asset is zero or positive at maturity. In this scenario, investors would receive their full principal amount plus the return of the Reference Asset times the Upside Participation Rate, with no maximum return cap. o  Scenario 2: The return of the Reference Asset is negative at maturity, BUT not by more than the Buffer. In this scenario, investors would receive only their full principal amount at maturity. o  Scenario 3: The return of the Reference Asset is negative at maturity by MORE THAN the Buffer Level. In this scenario, investors would lose 1% for every percent that the return of the Reference Asset is beyond the Buffer. For instance, if the Reference Asset has decreased by 20% and the Buffer is 15%, the Buffered Uncapped Note would return -5% at maturity. ·  It is important to note that if the return of the Reference Asset is less than the Buffer, investors will be exposed to an investment loss.   How do the Buffered Uncapped Notes work? ·  These investments offer two important features: (1) an Upside Participation Rate of at least 100%, in any positive performance of an equity index or ETF with no maximum return cap and (2) limited downside protection in the form of a pre-determined Buffer at maturity. ·  At maturity, there are three possible scenarios based on the performance of the Reference Asset: o  Scenario 1: The return of the Reference Asset is zero or positive at maturity.
