Standard MH per unit = 32,000 MH 6,400 units = 5 MH per unit
No. of units manufactured during the period = standard allowed MH standard
MH/unit = 30,000 MH 5 MH/unit = 6,000 units
Budgeted no. of units/setup = 6,400 units 32 set-ups = 200 units/set-up
Standard no. of setups for the units manufactured = 6,000 200 = 30

overhead in the master budget practical capacity (MH)
Setup cost = $64,000 + ($600/setup × 32 setups) = $ 83,200

VOH: 35,000 × $7.60 = 266,000 30,000 × $7.60 = 228,000
FOH: 200,000 200,000
Total OH $480,000 $466,000 $428,000
Notice that assumptions made regarding the number and type of activity measures used
to apply standard overhead costs to production can affect both the total flexible-budget
variance and the components of this variance. For this reason, the activities used to
construct flexible-budgets for control purposes should be carefully selected.

The difference (variances) reported when the denominator activity level is defined as
"practical capacity" can be interpreted as the "cost of unused capacity." This information
can be reported over time (time-series basis) to management to determine whether
some of the available capacity should be eliminated or whether some alternative uses to
this available capacity can be made. Notice that when practical capacity is used as the
denominator, there is consistency between the numerator and denominator: the

15-37 Use of Payoff Tables (Appendix); Spreadsheet Application (30-45 minutes)
(1) Expected value of the decision to investigate the variance:
E(Investigate) = [(I × (1 −p)] + [(I + C) × p]
(2) Payoff table:
Management States of Nature (prob.) Expected
Action Random (75%) Systematic (25%) Value
(3) Let p = the indifference probability, that is, the probability of for a nonrandom
variance such that management is indifferent between the two courses of action,
investigate or do not investigate:
p = I ÷ (L − C)
where I = the expected cost to conduct an investigation, L = expected loss
associated with leaving an out-of-control process out of control (i.e., the present
value of losses the organization will experience until the next decision point), and
C = the expected cost to correct the process if the variance is found to have a
nonrandom cause.
Thus, if the probability (p) for a nonrandom cause (or causes) is 4.96%,
management would be indifferent, in expected value terms, between investigating

15-38 Capacity Levels and Fixed Overhead Rates (60 minutes)
1. As the name suggests, maximum (theoretical) capacity is the maximum output
level for the plant, one that assumes operating at maximum efficiency. This
level of productivity suggests no “down time” for machine maintenance, no
internal disruptions to the manufacturing process, and no slack in external
(expected sales demand over an upcoming three- to five-year period).
