 gradually reduced until it is de-weighted entirely. Similarly, once trading activity at a Constituent Trading Platform resumes, the corresponding weighting for that Constituent Trading Platform is gradually increased until it reaches the appropriate level. 

•Manipulation Resistance: In order to mitigate the effects of wash-trading and order book spoofing, the Index only includes executed trades in its calculation. Additionally, the Index only includes Constituent Trading Platforms that charge trading fees to its users in order to attach a real, quantifiable cost to any manipulation attempts.

The Index Provider re-evaluates the weighting algorithm on a periodic basis, 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 Sponsor believes the Index Provider’s selection process for Constituent Trading Platforms as well as the methodology of the Index Price’s algorithm provides a more accurate picture of ZEC price movements than a simple average of Digital Asset Trading Platform spot prices, and that the weighting of ZEC prices on the Constituent Trading Platforms limits the inclusion of data that is influenced by temporary price dislocations that may result from technical problems, limited liquidity or fraudulent activity elsewhere in the ZEC spot market. By referencing multiple trading venues and weighting them based on trade activity, the Sponsor believes that the impact of any potential fraud, manipulation or anomalous trading activity occurring on any single venue is reduced.

If the Index Price becomes unavailable, or if the Sponsor determines in good faith that such Index Price does not reflect an accurate price for ZEC, then the Sponsor will, on a best efforts basis, contact the Index Provider to obtain the Index Price directly from the Index Provider. If after such contact such Index Price remains unavailable or the Sponsor continues to believe in good faith that such Index Price does not reflect an accurate price for ZEC, then the Sponsor will employ a cascading set of rules to determine the Index Price, as described below in “—Determination of the Index Price When Index Price is Unavailable.”

The Trust values its ZEC for operational purposes by reference to the Index Price. The Index Price is the value of a ZEC as represented by the Index, calculated at 4:00 p.m., New York time, on each business day.
