 (3) appropriately handle and adjust for non-market related events. The Index Price is determined by the Index Provider through a process in which trade data is cleansed and compiled in such a manner as to algorithmically reduce the impact of anomalistic or manipulative trading. This is accomplished by adjusting the weight of each data input based on price deviation relative to the observable set, as well as recent and long-term trading volume at each venue relative to the observable set. The Index Price is calculated using non-GAAP methodology and is not used in the Trust’s financial statements. All references to the NAV and NAV per Share of the Trust in this prospectus prior to the Trust’s listing on NYSE Arca have been calculated using the Index Price based on the CoinDesk SUI Reference Rate Price unless otherwise indicated. Prior to the listing of the Shares on NYSE Arca, the Sponsor intends to change the Index to the CoinDesk SUI CCIXber Reference Rate.
