The Sendal Co., Ltd., of Japan has budgeted costs in its various departments as follows for the coming year: Factory Administration Custodial Services Personnel Maintenance Machining-overhead Assembly-overhead Total cost $ 825, 470 108,831 28,970 60,569 633,098 865, 282 $2,522,220 The company allocates service department costs to other departments in the order listed below. Department Factory Administration Custodial Services Personnel Maintenance Machining Assembly Square Total Feet of Direct Number of Labor Space Labor- Machine- Employees Hours Occupied Hours Hours 7,000 - 7,200 11,900 19,100 8,000 52,600 17,300 120,000 45,000 61,000 140,800 114 160,000 15,000 235,000 35,200 310 358,900 104,200 296,000 176,000 59 76 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- Direct Labor- Hours 27 Hours 300 Machining Department Assembly Department Total hours 10 80 310 107 Using the overhead rates computed in (U). (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
