Insights

Regulatory Compliance Specialist

Amendment reflects administrative reallocation of beneficial ownership within Vanguard.

The filing cites SEC Release No. 34-39538 and an internal realignment effective January 12, 2026, explaining that subsidiaries will report on a disaggregated basis. The statement indicates that The Vanguard Group no longer is deemed to beneficially own the reported shares.

Because this is a disclosure-driven reattribution rather than a market trade, the practical effect is administrative; subsequent filings from the named subsidiaries will show the actual holdings.

Institutional Ownership Analyst

Reported 0 ownership removes Vanguard as a beneficial holder in this filing, but ownership likely appears under separate Vanguard entities.

The amendment shows Amount beneficially owned: 0 and Percent of class: 0%. This is a reallocation of reporting responsibility; the underlying investment strategy is stated to be unchanged.
