4) The management of Shastri Corporation would like to investigate the possibility of
basing its predetermined overhead rate on activity at capacity rather than on the
estimated amount of activity for the year. The company’s controller has provided an
example to illustrate how this new system would work. In this example, the allocation
base is machine-hours and the estimated amount of the allocation base for the upcoming
year is 69,000 machine-hours. In addition, capacity is 76,000 machine-hours and the
actual activity for the year is 71,600 machine-hours. All of the manufacturing overhead
is fixed and is $3,461,040 per year. For simplicity, it is assumed that this is the
estimated manufacturing overhead for the year as well as the manufacturing overhead at
capacity and the actual amount of manufacturing overhead for the year. Job Z67J,
which required 330 machine-hours, is one of the jobs worked on during the year.
Required:
a. Determine the predetermined overhead rate if the predetermined overhead rate is
based on the estimated amount of the allocation base.
b. Determine how much overhead would be applied to Job Z67J if the predetermined
overhead rate is based on estimated amount of the allocation base.
c. Determine the underapplied or overapplied overhead for the year if the predetermined
overhead rate is based on the estimated amount of the allocation base.
d. Determine the predetermined overhead rate if the predetermined overhead rate is
based on the amount of the allocation base at capacity.
e. Determine how much overhead would be applied to Job Z67J if the predetermined
overhead rate is based on the amount of the allocation base at capacity.
f. Determine the underapplied or overapplied overhead for the year if the predetermined
overhead rate is based on the amount of the allocation base at capacity.
