Melanie, a Senior Auditor, encountered the following independent scenarios during her examination of Inventory and related ledger accounts at Taylor Electronic Systems Inc. (TESI):

(a) several TESI trucks containing finished goods inventory were parked at the shipping dock, the contents of the trucks were included in TESI's finished goods inventory accounting records

(b) finished goods inventory at TESI included products with old packaging and products covered in dust - the warehouse manager stated "all of these products will eventually be sold - some price adjustments may be required"

(c) while reviewing the unit product cost calculations for finished goods inventory at TESI, the auditor noted that engineering costs were treated as period costs in previous years but were treated as product costs this year

(d) TESI implemented a new perpetual inventory management system during the year and the auditor noted that several inventory record quantities differed from the actual physical inventory count values, as a result, TESI performed a complete physical inventory count at year-end

(e) inventory at TESI's warehouse consisted primarily of "finished goods available for sale", however, goods held on consignment and customer's goods in for repairs were also in the warehouse - these non-owned goods were often difficult to distinguish from TESI's "finished goods available for sale".
