Ownership & management
Current ownership uses CURRENT OWNED_BY evidence only. UNKNOWN is not a former owner.
These relationships were observed in an older snapshot. UNKNOWN does not mean former owner, previous owner, or that ownership ended.
Ownership change history
No CMS ownership-change event is currently attached to this profile in the Trust Hub research graph. That is not proof that ownership never changed.

Profile generated 2026-11-04. That timestamp is not CMS evidence freshness.
