15 58 cost management

Able Control Company, which manufactures electrical switches, uses a standard cost system and carries all inventory at standard cost. The standard factory overhead cost per switch is based on direct labor hours:

 

Variable overhead 5 hours at $8.00 /hour $40.00

Fixed overhead* 5 hours at $12.00 /hour $60.00

Total standard overhead cost per unit produced $100.00

Based on a practical capacity of 300,000 direct labor hours per month.

 

The following information is for the month of October:

 

The company produced 56,000 switches although, 60,000 switches were scheduled to be produced

The company worked 275,000 direct labor hours at a total cost of $2,550,000

Variable overhead costs were $2,340,000

Fixed overhead costs were $3,750,000

 

The production manager argued during the last performance review that the company should use a more up-to-date base for charging factory overhead costs to production. She commented that her factory had been highly automated in the last two years and, as a result, now has hardly any labor. The factory hires only highly skilled workers to set up production runs and to do periodic adjustments of machinery whenever the need arises.
