CMA Intermediate · Cost Accounting · Overheads

As per the usual treatment of overheads in cost accounting, the cost of abnormal idle time arising from a power failure in a factory should be:

Abnormal idle time caused by a power failure is excluded from product cost and charged to the Costing Profit and Loss Account, because it is an abnormal loss and not a normal cost of production.

  1. ACharged to the cost of production as part of factory overheads
  2. BAdded to the closing stock value of work-in-progress
  3. CExcluded from product cost and charged to the Costing Profit and Loss AccountCorrect
  4. DSpread over all units produced in the following period

Explanation

Abnormal idle time and similar abnormal costs are not a normal part of production cost. They are written off to the Costing Profit and Loss Account. Charging them to production would inflate product costs and inventory values.
