Overhead rates were based upon normal and expected monthly capacity, both of which
were 4,000 direct labor hours. Practical capacity for this department is 5,000 direct labor
hours per month. Variable overhead costs are expected to vary with the number of direct
labor hours actually used.
During October, 900 transformers were produced. This was below expectations because a
work stoppage occurred during contract negotiations with the labor force. Once the
contract was settled, the wage rate was increased to $7.25/hour and overtime was

The following costs were incurred in October:
600 of the 1,400 hours were subject to overtime premium. The total overtime premium is
included in variable overhead in accordance with company accounting practices.
