Answer:
Craftmore Machining
1. Classification of activity as unit level, batch level, product level, or facility level:
Production Activity Level
Indirect Labor Facility
Indirect Materials Product
Grinding Product
Polishing Product
Product modification Product
Providing power Facility
System calibration Batch
2. The Activity Overhead Rates using ABC:
Grinding = $24.62/machine hour
Polishing = $10.38/machine hour
Product modification = $400/eng.h
Providing power = $15/DLH
System calibration = $1.25/batch
3. Assignment of overhead costs:
Job 3175 Job 4286
Number of units 200 units 2,500 units
Machine hours 550 MH 5,500 MH
Engineering hours 26 eng hours 32 eng. hours
Batches 30 batches 90 batches
Direct labor hours 500 DLH 4,375 DLH
Job 3175 Job 4286
Grinding = $24.62/machine hour $13,541 $135,410
Polishing = $10.38/machine hour 5,709 57,090
Product modification = $400/eng.h 10,400 12,800
Providing power = $15/DLH 7,500 65,625
System calibration = $1.25/batch 37.50 112.50
Total costs allocated $37,187.50 $271,037.50
Cost per unit $185.94 $108.42
4. Overhead cost per unit:
Job 3175 , Overhead cost per unit = $185.94 ($37,187.50/200)
Job 4286 Overhead cost per unit = $108 ($271,037.50/2,500)
5. Plantwide overhead rate
Total overhead costs = $1,810,000
Total direct labor hours = 4,875
Overhead rate = $1,810,000/4,875 = $371.28
Job 3175 Job 4286
Direct labor hours 500 DLH 4,375 DLH
Total overhead cost $185,640 $1,624,350
Overhead cost per unit $928.20 $649.74
6. Overhead cost per unit Job 3175 Job 4286
Using ABC $185.94 $108.42
Using Plantwide rate $928.20 $649.74
ABC rate more accurately assigns overhead costs than using plantwide rate.
Step-by-step explanation:
a) Data and Calculations:
Production Activity
Indirect Labor
Indirect Materials
Other Overhead Costs Usage Usage Rate
Grinding $320,000 13,000 machine hours $24.62/mh
Polishing $135,000 13,000 machine hours $10.38/mh
Product modification 600,000 1,500 engineering hours $400/eng.h
Providing power $255,000 17,000 DLH $15/DLH
System calibration 500,000 400 batches $1.25/batch
Total overhead $1,810,000
b) Craftmore incurs unit-level costs each time a unit is produced. It incurs batch-level costs each time it produces a batch of goods. It incurs product-level costs to support the production of each type of product. Finally, Craftmore's facility-level costs sustain the facility's general manufacturing process.
