The following misstatements are included in the inventory and related records of Westbox Manufacturing Company:

2. In taking the physical inventory, the last shipments for the day were excluded from inventory and were not included as a sale until the subsequent year.

4. After the auditor left the premises, several inventory tags were lost and were not included in the final inventory summary.
5. When raw material acquisitions were recorded, the improper unit price was included in the perpetual inventory master file. Therefore, the inventory valuation was misstated because the physical inventory was priced by referring to the perpetual records.
6. During the physical count, several obsolete inventory items were included.
7. Because of a significant increase in volume during the current year and excellent control over manufacturing overhead costs, the manufacturing overhead rate applied to inventory was far greater than actual cost.
