• Outgoing officer: Edward McGee stepped down after 7 years of service; departure is not due to any disagreement with the company.

Why It Matters
A change in the sponsor’s finance leadership affects who is responsible for financial reporting and accounting oversight for the ETF. The filing indicates continuity (two experienced finance executives were named immediately and the departure was voluntary and on good terms), which can help reduce operational disruption. Investors should note the leadership change when evaluating future disclosures or any changes in financial controls or reporting cadence.
