Airlines Reporting Corporation (ARC) Specialist Training Practice Test

Understanding stock accountability in ARC means distinguishing items that are tracked in the agency’s settlement (accountable) from those that aren’t (non-accountable). Non-accountable stock items are used for day-to-day operations and don’t impact the ARC settlement, so they don’t get posted to the agency’s financial reconciliation. In this set, REN, AAD, and Mini Itins are treated as non-accountable stock items, meaning they don’t enter the settlement process. The item that is not a non-accountable stock item—i.e., it is an accountable stock item—will be tracked in the settlement because it affects ticketing records and revenue. So ATBs is the item that is NOT a non-accountable stock item.
