An Authorized Participant will deliver, or cause to be delivered, cash to the Trust when it purchases Shares from the Trust, and the Trust will deliver cash to an Authorized Participant, or its designee, when it redeems Shares with the Trust. Authorized Participants, and their customers, may then, in turn, offer Shares to the public at prices that depend on various factors, including the supply and demand for Shares, the value of the Trust’s assets, and market conditions at the time of a transaction.

The statement of assets and liabilities and schedule of investment as of September 30, 2024, and the statements of operations, cash flows, and changes in net assets for the period ended September 30, 2024, have been prepared on behalf of the Trust and are unaudited.
