- Reported Ownership Change: The filing indicates a drop to 0 shares beneficially owned by this specific CIK entity.
- Context: The filing explicitly states: "On January 12, 2026, The Vanguard Group, Inc. went through an internal realignment... certain subsidiaries... will report beneficial ownership separately."
