The Trust's Board of Trustees has redesignated existing shares of the fund as "Institutional Shares" because of the creation of another share class of the fund, Token-Enabled Shares, which are offered by a separate prospectus that is also dated January 26, 2026.
Effective immediately, the fund's prospectus dated August 28, 2025, is hereby revised as follows:
All references to "shares" of the fund are hereby replaced with "Institutional Shares."
PLEASE BE SURE TO RETAIN THIS IMPORTANT INFORMATION FOR FUTURE REFERENCE.
