Six bases used for applying factory overhead are units produced, direct materials cost, direct labor cost, direct labor hours, machine hours, and transactions.. If factory overhead costs
Trang 1Q12-1 Supervisors’ salaries, indirect labor, overtime
premium, supplies, indirect materials, payroll
tax, factory insurance, and depreciation.
Q12-2 The most important reason for variation in
fac-tory overhead is the presence of fixed and
variable expenses Therefore, as production
volume changes from month to month, the
costs will do likewise However, overhead also
will change because of improved or decreased
efficiencies and changes in prices paid for
overhead items such as supplies and repairs.
Q12-3 Predetermined rates are used when it
becomes obvious that any other method of
charging overhead results in inequitable
cost-ing and delays the reportcost-ing of financial
results Charging actual overhead to jobs and
products can result in charging unreasonable
amounts of overhead to various periods and
in delayed reporting of cost data The use of
predetermined rates also enhances control
through analysis of over- or underapplied
fac-tory overhead.
Q12-4 Six bases used for applying factory overhead
are units produced, direct materials cost,
direct labor cost, direct labor hours, machine
hours, and transactions Important
considera-tions in selecting a base are the relaconsidera-tionship
(correlation) of the base used and the use of
overhead items in manufacturing operations,
as well as the clerical practicability of using a
particular base.
Q12-5 Predetermined rates are used to charge
over-head and become the basis for determining
the cost of a job or product Therefore, the
rea-sonableness of such costs is to a large extent
determined by the reasonableness of the
rates Since these costs are used for costing
inventories and play an important role in
estab-lishing sales prices, the selection of proper
pre-determined rates can be appreciated.
Q12-6 An objective in selecting the base for a
prede-termined factory overhead rate is to ensure
the application of factory overhead in
reason-able proportion to a beneficial or causal
rela-tionship to jobs, products, or work performed
or to be performed, i.e., for estimating pur-poses Ordinarily, the base selected should be closely related to functions represented by the applied overhead cost If factory overhead costs are predominantly labor oriented, such
as supervision and indirect labor, the proper base would probably be direct labor hours If factory overhead costs are predominantly related to the cost incurred in the ownership and operation of the machinery, the proper base would probably be machine hours Another objective in selecting the base is
to minimize clerical cost and effort relative to the benefits attained When two or more bases provide approximately the same applied overhead cost to specific units of pro-duction, the simplest base should be used Q12-7 (a) Theoretical capacity is actually the
maxi-mum production possible from a given plant with no allowance made for cessation
of operations for holidays, weekends, mate-rials shortages, or machine breakdowns (b) Practical capacity is theoretical capacity less an allowance for interruptions such
as breakdowns, delays in receiving sup-plies, and worker absences Practical capacity is usually 75 to 85 percent of theoretical capacity.
(c) Expected actual capacity is practical capacity adjusted for the lack of sufficient demand in a single operating period and may be used in building operating budg-ets when expected capacity differs sub-stantially from normal capacity.
(d) Normal capacity is practical capacity adjusted to give consideration to the lack
of sufficient demand over a period long enough to include cyclical and seasonal fluctuations This is usually the basis for long-range planning, standards, and preferably for the determination of over-head rates.
Q12-8 The underapplied overhead will be higher If
maximum capacity is used and lower if nor-mal is used If this cost is charged to the
Trang 2current period, then maximum capacity will
produce a lower, and normal capacity a
higher, operating profit.
Q12-9 (a) Idle capacity costs arise from idle
employ-ees and idle facilities Idle employemploy-ees give
rise to costs such as base wages paid,
employer’s share of payroll taxes, and
other fringe benefit costs Idle facilities
cause capacity costs due to deterioration
with time, approaching obsolescence,
costs for upkeep, readiness,
mainte-nance, repairs, shelter, and protection of
valuables such as insurance.
(b) When idle capacity is present, an attempt
should be made to segregate idle
employees and idle facilities through
proper reclassification The accumulation
of the cost attributable to these idle
work-ers or facilities in excess of a reasonable
budgeted amount might be in some kind
of overhead account to be treated
sepa-rately as a “management by exception”
factor Idle capacity costs should be
accounted for separately for these
rea-sons: (1) to prevent distortion and
confu-sion in the analysis of production costs;
(2) to facilitate income determination; (3)
to control operations; and (4) to plan next
year’s budget adequately.
(c) Excess capacity cost has been identified
with those capacity costs that result from
greater production capacity than the
com-pany could ever hope to use, or from
unbalanced equipment or machinery
within departments In creating the
fore-cast budget, it is important to isolate the
excess capacity cost so that
manage-ment can be made aware of its
responsi-bility regarding the excess investment in
labor and machines.
Q12-10 (a) Analyze and identify the overhead
trans-actions.
(b) Journalize the transactions.
(c) Enter transactions in general and sub-sidiary ledgers.
Q12-11 Overhead applied to production is entered
as a credit in the factory overhead control account Actual overhead is debited to the same account Therefore, overhead has been overapplied when the account has a credit balance.
Q12-12 Overhead can be overapplied because (a)
actual overhead was less than budgeted; (b) capacity utilized was greater than that esti-mated in computing overhead rates; (c) the overhead estimate was too high (a mistake); (d) the production estimate was too low (a mistake); (e) combinations of the above Q12-13 Over- or underapplied factory overhead may
be prorated among work in process, finished goods, and cost of goods sold, or it may be treated entirely as a period cost The first method would have a smaller effect on cost
of goods sold and therefore on the net income for the period.
Q12-14 The existence of large underabsorbed
vari-ances does not necessarily mean that unit costs are incorrect An analysis of the under-absorbed figures will indicate (a) whether actual overhead is too high or whether expenses have been incorrectly estimated; and (b) what part of the underabsorption is caused by unused capacity If actual over-head is considered to be too high and there
is idle capacity, unit costs computed are more reasonable than they would be if over-head rates were computed to absorb all of the actual overhead.

(1) $1,750,000 fixed overhead and $720 variable overhead per ton, calculated as
follows:
For both the normal capacity and expected actual capacity, the problem states the total budgeted overhead cost and the number of tons of activity The high-low method of estimating cost behavior can be used to determine the over-head budget, using those two points:
Budgeted
Variable
overhead rate
Budgeted fixed overhead = $5,350,000 total overhead
– ($720 × 5,000) variable overhead
= $5,350,000 – $3,600,000 = $1,750,000
or, budgeted
– ($720 × 6,000) variable overhead
= $6,070,000 – $4,320,000 = $1,750,000

(2) The predetermined rate at practical capacity would be $938.75 per ton Using
the budget for fixed and variable overhead, a predetermined overhead rate can
be calculated at any level of activity within the relevant range Assuming prac-tical capacity is within that range, the calculation is:
Predetermined

(8,000 tons)
Budgeted fixed overhead + Budgeted variable
or, $720 variable overhead per ton + ($1,750,000/8,000 tons)
= $720 per ton + $218.75 per ton = $938.75 per ton.

(1) Actual overhead incurred $3,470,000
Applied overhead* 3,325,000
Underapplied overhead $ 145,000
*actual MH × predetermined rate based on expected actual capacity
= 9,500 MH × ($3,500,000/10,000 MH)
= 9,500 MH × $350 per MH = $3,325,000
(2) The predetermined rate at practical capacity would be $316.67 per machine
hour (MH), calculated as follows:
First, find the budgeted total fixed overhead and the budgeted variable over-head rate per MH The problem states both the total budgeted overover-head cost and the number of MH of activity, at both the normal capacity and expected actual capacity levels, so the high-low method of estimating cost behavior can
be used:
Variable
overhead rate
Budgeted fixed overhead = $3,500,000 total overhead
– ($250 × 10,000) variable overhead
= $3,500,000 – $2,500,000 = $1,000,000
or, budgeted
fixed overhead = $3,000,000 total overhead
– ($250 × 8,000) variable overhead
= $3,000,000 – $2,000,000 = $1,000,000
Then, using the budget for fixed and variable overhead, a predetermined overhead rate can be calculated at any level of activity within the relevant range Assuming practical capacity is within that range, the calculation is:

(3) If the actual overhead of $3,470,000 were underapplied by $10,000, then Applied
