The Trust has no employees, officers or directors and is managed by the Sponsor. None of the directors or officers of the Sponsor receive compensation from the Trust. The Trust pays the Sponsor a Sponsor Fee of 0.25% per annum of the Trust’s average daily net assets. The Sponsor Fee is calculated on a daily basis (accrued at 1/365, or 1/366 in a leap year, of the applicable Sponsor Fee percentage multiplied by the Trust’s NAV) and paid on a monthly basis. The Sponsor previously waived the entire Sponsor Fee on the first $1 billion of Trust assets for the 6-month period commencing on the day the Trust’s Shares were initially listed on the Exchange. Effective July 11, 2024, this waiver expired, and the Sponsor is no longer waiving the Sponsor Fee. The Sponsor may, in its sole discretion and from time to time, waive all or a portion of the Sponsor Fee for stated periods of time. For the fiscal year ended December 31, 2025, the Trust incurred a Sponsor Fee of $515,401 of which $485,363 had been paid as of December 31, 2025. For the month of December 2025, the Trust incurred a Sponsor Fee of $30,038, which was unpaid as of December 31, 2025, and is reported as a liability on the Statement of Assets and Liabilities.
