What is the treatment of abnormal waste in inventory costing?

• A. Abnormal waste is included in inventory cost.
• B. Abnormal waste is recorded as a separate asset.
• C. Abnormal waste is not included in inventory cost; recognize as a period expense.
• D. Abnormal waste is ignored.

Answer: (C)

In inventory costing, abnormal waste is treated as a period expense rather than part of the inventory cost. Normal waste is considered a normal part of production and is included in the cost of inventory, but waste beyond what is expected under normal operating conditions signals inefficiency and should not be capitalized. By expensing the abnormal waste in the period it occurs, the inventory value reflects only normal resource consumption, and the period’s results show the inefficiency separately.

Including abnormal waste in inventory would inflate inventory value and net income in the current period. Recording it as a separate asset would misclassify a loss as a future benefit. Ignoring it would fail to recognize a real expense.
