All Manufacturing Variances Eastern Company manufactures special electrical equipment and parts. The company uses a standard cost system with separate standards established for each product. The transformer department manufactures a special transformer. This department measures production volume in terms of direct labor hours (DLHs) and uses a flexible-budget system to plan
and control departmental overhead costs.
Standard costs for the special transformer are determined annually in September for the coming year. The standard cost of a transformer at its DeCatur plant for the year just completed is $67 per unit, as shown here:

Overhead rates were based on practical capacity of 4,000 DLHs per month. Variable overhead costs are expected to vary with the number of DLHs actually used.
During October, the plant produced 800 transformers. This number was below expectations because a work stoppage occurred during labor contract negotiations. When the contract was settled, the department scheduled overtime in an attempt to reach expected production levels.
The following costs were incurred in October:
Direct Material
Iron Purchased 5,000 sheets at $2.00/sheet and used 3,900 sheets
Copper Purchased 2,200 spools at $3.10/spool and used 2,600 spools
Direct Labor
Regular time 2,000 hours at $7.00 and 1,400 hours at $7.20
Overtime 600 of the 1,400 hours were subject to overtime premium. The total overtime premium of $2,160 is included in variable overhead in accordance with company accounting practices.
Factory Overhead
Variable $12,000
Fixed $8,800
