In: Accounting
Sarah Corp. is a manufacturing firm which has two service
departments, General plant administration and Storeroom, and two
production departments, Machining and Assembly. The General plant
administration Department costs of $100,000 are allocated on the
basis of indirect labor hours. The Storeroom Department costs of
$25,000 are allocated based on the number of requisitions. The
costs of production departments, Machining and Assembly, are
$560,000 and $450,000, respectively.
Data on overhead costs, and information about the indirect labor
hours and number of requisitions given as percentages (e.g., 13% is
shown as 0.13), are as follows:
Service Departments | production Departments | |||
| General plant administration Department | Storeroom Department | Machining Department | Assembly Department |
Overhead costs: | $100,000 | $25,000 | $560,000 | $450,000 |
indirect labor hours (percent) | 0.02 | 0.08 | 0.28 | 0.62 |
number of requisitions (percent) | 0.21 | 0.10 | 0.37 | 0.32 |
Overhead rates are established for each of the production
departments. The Machining Department allocates overhead based upon
machining hours and the Assembly Department allocates overhead
based upon assembly direct labor hours. The planned levels are
7,000 machining hours and 18,600 assembly direct labor hours.
Allocate costs to the production departments using the direct
method, then find the overhead rates for the Machining and Assembly
departments.
