 on the price and trading volume data of the Digital Asset Trading Platforms included in the Index over the preceding 24-hour period. The Index Price is calculated using non-GAAP methodology and is not used in the Trust’s financial statements.The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. Still, the Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions (“IOSCO”) principles for financial benchmarks. For an exchange to become a Constituent Trading Platform (as defined herein), it must satisfy the Inclusion Criteria described in the Annual Report, as may be updated by the Index Provider from time to time. See “—Risk Factors—Risk Factors Related to the Digital Asset Markets—The Index Price used to calculate the value of the Trust’s Bitcoin may be volatile, and purchasing and selling activity in the Digital Asset Markets associated with Basket creations and redemptions may affect the Index Price and Share trading prices, adversely affecting the value of the Shares.” |
