## Problem 1: Job Order Costing Cycle

Excellent Ltd. had the following inventories on 1 April 2019:

During the month, the cost of materials purchased was \$120,000. Also, the direct labor cost was \$160,000 and factory overhead applicable to production was \$60,000. On 30 April, the inventories were as follows:

Required: Prepare journal entries on April 30 to show the flow of cost through the proper summary accounts, and also give the subsidiary records.

## Problem 2: Charging Actual FOH to Jobs

The Moon Manufacturing Co. has a partial job order costing system instead of predetermining a factory overhead rate.

The company computes a separate factory overhead rate at the end of each month.

This rate is used to charge the factory overhead to the jobs worked on during the month. The number of direct labor hours used on the jobs is the basis of such allocation.

The table below shows the actual factory overhead costs and the direct labor hours for May and June.

During this two-month period, one customer sent in an identical order each month, calling for the production of 1,000 units. This required 400 direct labor hours at \$1 per hour and materials amounting to \$750.

Required:

• Calculate the total cost and unit cost for the job across the two months
• Comment on the method of charging actual factory overhead costs to jobs

### Solution

It is clear from the above calculation that charging actual FOH costs to jobs gives inaccurate and misleading results.

The company should use predetermined FOH rates for correct calculations and control.
