Inventory of Gov. owned or Furnished Material (GFM)   A physical inventory of GFM accountable to sponsored projects is conducted biennially using the methodology discussed above. It is performed within the period of time allotted for the biennial inventory for equipment on the project, unless otherwise required by the sponsor or the circumstances. Material items are not usually bar-coded. Quantities are verified in a method appropriate to the type of material. The inventory of GFM is limited to the balance on hand items. Records for material will be maintained by a departmental representative in the PMO Material Tracking Database, unless otherwise authorized by the Office of Naval Research or the Sponsor. (See Records chapter). Inventory of Government owned or furnished property at subcontractor facilities Government-owned property at subcontractor facilities, for which Stanford University is ultimately accountable, must also be inventoried in sync with the biennial inventory schedule, or as otherwise required by the accountable sponsored project. PMO will work closely with the DPA and subcontractor to ensure the inventory is completed and reported as required by the sponsor requirements.
