This is the policyLevel property of a 64-bit threshold definition object, the definition of one 64-bit-valued statistics threshold, used for larger cumulative counters such as total bytes transferred, that belongs to a threshold policy, reflecting where in the UCS org hierarchy the governing policy for this instance was resolved from. An admin troubleshooting unexpected policy behavior on a 64-bit threshold definition can use this value to see whether the setting in effect came from the root organization, a sub-organization, or the local object itself. For example, if a 64-bit threshold definition under a threshold policy is not behaving as its local settings suggest, checking policyLevel here can reveal that a higher-level org policy is actually the one taking precedence.
