Records needed for this question
Asset ownership, rental terms and maintenance schedules.
How to investigate
Match serial numbers to rental lines and distinguish owned devices from managed-service assets.
An illustrative review decision
If equipment was bought outright but a rental line remains, gather the purchase and service change records. A purchase of one router does not establish ownership of every device on the account.
What can lead to the wrong conclusion?
A maintenance charge may survive a hardware purchase under a separate agreement.
The result to retain
An ownership-and-service schedule for challenged rentals.
