SAS ASSET INVENTORY One step annual independent asset verification conducted by the equipment’s custodian and an Asset administrator completed on a 9-month cycle. INVENTORY Every two years the PI will receive a list of assets of which he/she is listed as the custodian. The list will detail asset number, name, PO number, asset location and custodian’s name. The custodian verifies the existence and location of the assets, makes necessary changes on the list and returns the list to SAS’s asset Administrator. All changes and corrections are made by the Asset Administrator in the BEN Asset system. New assets will be ‘tagged’ during this process.
