The Fund values each Fund Component it holds for operational purposes by reference to an Index Price. The "Index Price" of each Fund Component is the U.S. dollar value of each Fund Component derived from the Constituent Trading Platforms that are reflected in each Fund Component's CoinDesk Benchmark Rate, calculated at 4:00 p.m., New York time, on each business day.

Prior to the changes announced on May 19, 2026, the Constituent Trading Platforms used to calculate the Index Price for each respective Fund Component were as follows:

Effective May 19, 2026, the Index Provider added OSL (BTC-USD, ETH-USD, and SOL-USD trading pairs), Bybit (BTC-USD and ETH-USD trading pairs), and Gemini (BNB-USD trading pair) as Constituent Trading Platforms used to calculate the Index Prices for Bitcoin, Ether, SOL, and BNB due to the trading platforms meeting the Index Provider's conditions for inclusion, and did not remove any Constituent Trading Platforms as part of its scheduled monthly review. As of the date of this current report, the Constituent Trading Platforms used to calculate the Index Price for each respective Fund Component were as follows:

The Index Provider may change the trading venues that are used to calculate an Index Price, or otherwise change the way in which an Index Price is calculated, at any time. For example, the Index Provider has scheduled monthly reviews, in which it may add or remove Constituent Trading Platforms that satisfy or fail the criteria described in "Item 1. Business-Overview of the Digital Asset Industry and Market-The Index Prices" in the Fund's Annual Report on Form 10-K for the year ended June 30, 2025, as filed with the Securities and Exchange Commission on September 5, 2025.
