No use or publication may be made of the Index, or any of its provisions or values, without the prior written consent of HSBC Bank pplc. Neither HSBC Bank plc nor its duly appointed successor, acting as index owner (the "Index Owner"), nor Solactive AG or its duly appointed successor, acting as index administrator ("Index Administrator") and index calculation agent ("Index Calculation Agent"), are obliged to enter into or promote transactions or investments that are linked to the Index. The Index Owner makes no express or implied representaions or warranties as to (a) the advisability of purchasing or assuming any risk in connection with any transaction or investment linked to the Index, (b) the levels at which the Index stands at any particular time on any particular date, (c) the results to be obtained by any party from the use of the Index or any data included in it for the purposes of issuing any financial instruments or carrying out any financial transaction linked to the Index or (d) any other matter. Calculations may be based on information obtained from various publicly available sources. The Index Administrator and the Index Calculation Agent have relied on these sources and have not independently verified the information extracted from these sources and accept no responsibility or liability in respect thereof. Use o s ula ed e u ns The Index was launched on November 8, 2019 and therefore has limited historical performance. As a result, limited actual historical performance information is available for you to consider in making an independent investigation of the Index, which may make it difficult for you to evaluate the historical performance of the Index and make an informed investment decision than would be the case if the Index had a longer trading history. Hypothetical back-tested performance prior to the launch of the Index provided in this document refers to simulated performance data created by applying the Index's calculation methodologies to historical prices of the underlying constituents and the reference rate. In addition, because certain of the Index Constituents (SPLV, HYG, EEM, EMB, GLD, and TIP) were not in existence at the start of the backtested period, adjustments have been made to calculate their performance prior to their inception. Such simulated performance dta has been produced by the retroactive application of a back-tested methodology in hindsight, and may give more preference towards underlying constituents that have performed well in the past. The hypothetical back-tested annualized performance and annulized volatility of the Index have inherent limitations. These performance and volatility results were achieved by means of a retroactive application of a back-tested volatility model designed with the benefit of hindsight. Hopythetical back-tested results are neither an indicator nor a guarantor of future results. The hypothetical back-tested performance of the Index prior to November 8, 2019 cannot fully reflect the actual results that would have occurred had the Index actually been calculated during that period, and should not be relied upon as an indication of the Index's future performance.
