The Sendai Co., Ltd., of Japan has budgeted costs in its various departments as follows for the coming year:
Factory Administration | $ | 1,063,750 |
Custodial Services | 125,540 | |
Personnel | 39,520 | |
Maintenance | 155,140 | |
Machining—overhead | 969,100 | |
Assembly—overhead | 875,450 | |
Total cost | $ | 3,228,500 |
The company allocates service department costs to other departments in the order listed below.
Department | Number of Employees |
Total Labor- Hours |
Square Feet of Space Occupied |
Direct Labor- Hours |
Machine- Hours |
Factory Administration | 27 | — | 11,700 | — | — |
Custodial Services | 11 | 13,400 | 2,900 | — | — |
Personnel | 14 | 17,400 | 12,600 | — | — |
Maintenance | 58 | 44,700 | 16,800 | — | — |
Machining | 100 | 150,000 | 52,500 | 46,000 | 232,000 |
Assembly | 150 | 200,000 | 17,500 | 229,000 | 29,000 |
360 | 425,500 | 114,000 | 275,000 | 261,000 | |
Machining and Assembly are operating departments; the other
departments are service departments. Factory Administration is
allocated based on labor-hours; Custodial Services based on square
feet occupied; Personnel based on number of employees; and
Maintenance based on machine-hours.
Required:
1. Allocate service department costs to consuming departments by the step-down method. Then compute predetermined overhead rates in the operating departments using machine-hours as the allocation base in Machining and direct labor-hours as the allocation base in Assembly.
2. Repeat (1) above, this time using the direct method. Again compute predetermined overhead rates in Machining and Assembly.
3. Assume that the company doesn’t bother with allocating service department costs but simply computes a single plantwide overhead rate that divides the total overhead costs (both service department and operating department costs) by the total direct labor-hours. Compute the plantwide overhead rate.
4. Suppose a job requires machine and labor time as follows:
Machine- Hours |
Direct Labor-Hours |
||||
Machining Department | 270 | 29 | |||
Assembly Department | 19 | 80 | |||
Total hours | 289 | 109 | |||
Using the overhead rates computed in (1), (2), and (3) above, compute the amount of overhead cost that would be assigned to the job if the overhead rates were developed using the step-down method, the direct method, and the plantwide method.
