Insights

Institutional Ownership Analyst

Disaggregation reduced reported Vanguard stake to zero; this reflects reporting structure changes, not a market sale.

The amendment explains an internal realignment and separate reporting by subsidiaries in reliance on SEC Release No. 34-39538 (January 12, 1998). The filing shows 0 shares and 0% beneficial ownership as reported.

Practical effect: the change is a reporting reallocation. Subsequent filings from the Vanguard entities may show beneficial holdings under different reporting names; timing and amounts are as reported on each entity's schedule.

Securities Compliance Counsel

Filing serves a compliance disclosure after corporate realignment, preserving regulatory traceability.

The text states that certain subsidiaries will report beneficial ownership separately and that Vanguard no longer is deemed to own those securities per the cited SEC release. The amendment is signed and dated.

Key compliance note: the amendment preserves the required disclosure chain; any material change in economic ownership would require additional filings by the relevant reporting entities.
