Trang 5Learning Objective 1
• Why are all costs controllable by
someone at some time, but in the short run some costs may be
classified as noncontrollable?
Trang 6Performance Reporting
• Involves the comparison of actual
results with planned results
• The objective is highlighting those
activities where planned and actual
results differ
• Appropriate actions may be taken to
address the causes of the favorable
or unfavorable variances
Trang 7Strategic, Operational, and Financial Planning
Planning and Control Cycle
Trang 8Relationship of Total Costs to
Volume of Activity
• Any differences between achieved and
planned performances should be evaluated
• As the level of activity changes from the
planned activity, total variable costs should
change
• The total amount of fixed costs should not
change with changes in levels of activity
Trang 9
+/-Cost Classification According
to a Time-Frame Perspective
• A noncontrollable cost is one which the
manager can do nothing to influence
the amount of the cost
• Noncontrollable costs occur in the short
run
• In the long run every cost is controllable
by someone in the organization
Trang 10Learning Objective 2
• How does performance reporting
facilitate the
management-by-exception process?
Trang 11Characteristics of the Performance Report
• A performance report compares actual
results to budgeted amounts
• It is an integral part of the control process
• The general format is as follows:
Budget Actual Activity Amount Amount Variance Explanation
Trang 12• Variances are usually described as either
favorable or unfavorable
• A favorable variance occurs when results
exceed planned activities in a positive
manner – revenues are larger than expected
• An unfavorable variance occurs when results exceed planned activities in a negative
manner – expenses are larger than expected
Trang 13
+/-Responsibility Reporting
• The explanation column in the performance report is to communicate to upper-level
management the causes of variances
• In responsibility reporting, higher levels of
management receive less details regarding lower levels in the chain of command
• Managers want to eliminate unfavorable
variances and retain favorable variances
Trang 14Management by Exception
• Managers concentrate their efforts only on
those activities that are not performing
according to the plan
• To aid in this effort, variances are often
expressed in percentages
• Only those variances that exceed a
predetermined percentage are investigated
Trang 15Frequency of Performance Reports
• Performance reports should be issued soon after the period in which the activity takes place
• If later, actions are forgotten or confused
• A question regarding performance reports is
whether noncontrollable expenses should be
reported
• May want managers to be aware of all costs, or
may want managers to deal only with controllable
Trang 17Reporting for Segments of
an Organization
• A segment is a division, product line, or
other organizational unit
• Using the contribution margin format,
sales, variable expenses, contribution
margin, fixed expenses, and operating
income are calculated for each segment
• Fixed expenses should be divided into
direct fixed expenses and common fixed expenses
Trang 18Segment Fixed Expenses
• Direct fixed expenses would be
eliminated if the segment were eliminated
• Common fixed expenses are an allocated portion of the organization’s fixed
expenses
• Common fixed expenses would not be
eliminated if the segment were eliminated
Trang 19Types of Segments
• A responsibility center is an element of
the organization over which a manager
has responsibility and authority
– Cost center – does not generate revenue
for the organization
– Profit center – generates revenue for the
organization
– Investment center – generates revenue
and controls assets of the organization
Trang 20Evaluating Segments
• Cost centers are evaluated by comparing
actual costs incurred to budgeted costs
• Profit centers are evaluated by comparing
actual segment margin to budgeted
segment margin
• Investment centers are evaluated by
comparing actual and budgeted return on
investment based on segment margin and
assets controlled by the segment
Trang 21Learning Objective 4
• What is a flexible budget, and
how is it used?
Trang 22Flexible Budget
• A flexible budget is one that reflects
budgeted amounts for actual activity
• Flexible budgeting does not affect the
predetermined overhead application
rate
• Therefore, fixed overhead will be
overapplied or underapplied
Trang 23Learning Objective 5
• How and why are the two
components of a standard cost
variance calculated?
Trang 24Analysis of Variable
Cost Variances
• The total variance for a cost component is
called the budget variance
• The budget variance is caused by two
Trang 25Variance Terminology
• Different variances are the responsibility
of different managers
• Must separate total variances so that
each manager can take appropriate
Trang 26Direct Labor Variances
• Direct labor efficiency variance is the quantity
variance for direct labor
• The direct labor efficiency variance is the difference between standard hours allowed and actual hours worked
• Direct labor rate variance is the cost per unit of
input variance
• The direct labor rate variance is the difference
Trang 27Learning Objective 6
• What are the specific names
assigned to variances for different product inputs?
Trang 28Variance Names
Cost per unit
Input Quantity of Input
Raw materials Usage Price
Direct labor Efficiency Rate
Variable overhead Efficiency Spending
Trang 29General Variance Model
• Quantity variance =
Standard Actual Standard
quantity - quantity X cost per
allowed used unit
• Cost per unit of input variance =
Standard Actual Standard
quantity - quantity X cost per
allowed used unit
Trang 30Graphical Representation
Actual quantity used Actual quantity used Standard quantity allowed
Actual cost per unit Standard cost per unit Standard cost per unit
Cost per unit of Input variance
Quantity variance
Trang 31Variance Analysis Objectives
• Objective is to highlight deviations from planned results
• Want to eliminate unfavorable variances and
capture favorable variances
• Need to analyze variances for each standard
• Usually raw materials usage variances and direct labor efficiency variances are reported frequently
Trang 32Raw Materials Purchase Variance
• Many firms calculate and report raw
materials price variances at the time the
materials are purchased rather than when they are used
• Modified purchase price variance:
Standard Actual Actual
cost per - cost per X quantity
unit unit purchased
Trang 33Learning Objective 7
• How do the control and analysis
of fixed overhead variances and
variable cost variances differ?
Trang 34Analysis of Fixed Overhead
• Analyzed differently from variable cost
variances
• The focus is on the difference budgeted
fixed overhead and actual fixed
overhead expenditures
• This difference is divided into a budget
variance and a volume variance
Trang 35Fixed Overhead Volume Variance
• Volume variance is the difference
between the amount of fixed overhead
applied to production and that planned to
be applied
• It is not appropriate to make per unit fixed overhead variance calculations because fixed costs do not behave on a per unit
basis
Trang 36Fixed Overhead Budget Variance
• The budget variance is the difference
between budgeted fixed overhead for the period and the actual fixed overhead for
Trang 37Learning Objective 8
• What are the alternative methods
of accounting for variances?
Trang 38Accounting for Variances
• If the total of all of the variance is not
significant, it is included with cost of goods
sold in the income statement
• Standard costs also are released to cost of
goods sold
• Therefore, cost of goods sold reports the
actual cost of the items
• If variances are large, the variances are
allocated between inventory and cost of
