SQL Server Audit Action Group:
SCHEMA_OBJECT_OWNERSHIP_CHANGE_GROUP
This group tracks changes of ownership on schema objects such as a table, view or stored procedure.
This is an important audit action group because ownership changes are significant to the security of the system.
If you enable this group in a database audit specification, it will track ownership changes on schema objects within that database only. If you enable this group in a server audit specification, it will track ownership changes on schema objects in all databases within that SQL Server instance.
