Ideally;
Inventory = Cost of raw materials + Cost of finished goods + Cost of work-in-progress
Assuming this ideal case, Harlan's inventory would be;
Inventory = $14,000+$25,000+$18,600 = $57,600
However, if work-in-progress inventory was listed as $0;
Then, the new work-in-progress would be;
Inventory = 57,600-18,600 = $39,000
This would reduce the inventory for Harlan Enterprises which may affect other financial ratios such as inventory turn-over ratio. As a result, such ratios will not reflect the exact position of the company.
