Insights

Institutional Ownership Specialist

Vanguard lists zero beneficial holdings in Hanover common stock after internal realignment.

The Schedule 13G/A states Amount beneficially owned: 0 and Percent of class: 0%, with disclosures about internal disaggregation under SEC Release No. 34-39538. This reflects a reporting allocation among Vanguard entities rather than an open-market trade.

Cash‑flow treatment or trading activity is not disclosed; subsequent filings may clarify whether any subsidiary reports holdings separately.

Securities Compliance Analyst

Filing is administrative and compliance‑focused, not a material position change.

The form is an amendment describing that certain Vanguard subsidiaries will report on a disaggregated basis following an internal realignment. The signature block is dated 03/27/2026, and the cover shows 03/13/2026.

Because the filing records 0 shares, it is routine disclosure under Schedule 13G/A and does not, by itself, alter investor metrics.
