Q1: Organizational Vision and Core Competencies

• The organizational vision is the core purpose and

ideology of the organization.

• Determining the organizational vision precedes all

other management decision making.

• Management must also isolate the organization’s

core competencies – its strengths relative to

competitors.

Q1: Monitoring and Motivating Performance

Actual

Operations

Organizational

Vision & Core

Competencies

Managers use the results of actual

operations to monitor performance and

ensure that it is in line with the

organizational vision.

Managers may find that the results of

actual operations make them re-think the

organizational vision or their view of the

organization’s core competencies.

If you had an accounting practice, can you think of an example of a

measure of actual operations and how you would use it to motivate

performance?

Can you think of an example of a measure of actual operations that

might make you redefine your organizational vision or your view of your

core competencies?

Q3: Strategic Cost Management

and the Balanced Scorecard

• Strategic cost management is an approach to

reducing costs while strengthening the

organization’s strategic position.

• The balanced scorecard can be used to formalize

strategic cost management efforts by detailing

financial and nonfinancial benchmarks for all

segments of the organization.

• Examples of such benchmarks include:

• Personnel can reduce costs by completing all hiring within 20

days of initial interview.

• Production can reduce costs and improve quality if Engineering

can reduce the number of processes in the production process.

Q4: What Information is Relevant

for Decision Making?

• Information is relevant if:

• Differs across the alternatives, and

• Is about the future.

• Relevant information can be quantitative or

qualitative

• Information is irrelevant if:

• Does not vary with the option chosen or action taken

Irrelevant information is NOT useful in

decision making!

• Relevant cash flows are future cash flows that

differ across the alternatives.

• also called incremental cash flows

• also called avoidable cash flows

• Irrelevant cash flows are:

• non-incremental and unavoidable cash flows

• do not vary among alternatives

• Must look at the cash flow relevance to the

decision being made

Q4: Relevance of Income Statement Information

• Income Statements include:

– Period costs

– Product costs (recorded as cost of goods sold)

• Many business decisions require the incremental

cost to produce a unit

• Cost per unit on the income statement includes

both fixed and variable costs

• Including fixed costs does not represent the true

incremental cost of a unit

• Uncertainties come from many sources and can be

exogenous or endogenous.

• The future is always uncertain.

• Managers may be uncertain that the right information

was captured in a report.

• Biases can come from many sources.

• The decision maker may be biased towards or against a

particular alternative (predisposition bias)

• The methods used to collect information could have

introduced bias (information bias)

• The decision maker may exercise an error in judgment or

processing information (cognitive bias)

Q8: Ethical Decision Making

Suppose you work for the Lee K. Fawcett Plumbing Company as Mr.

Fawcett’s administrative assistant. Recently Mr. Fawcett asked you to

type some financial statements from his hand-written notes so that he

can take them to the bank as part of a loan application.

This exercise seems odd to you because the company’s CPA recently

delivered the monthly financial statements that she prepares.

While typing the financial statements you notice that the building the

company rents is listed as an asset. Also, you write checks each month

for the monthly payments on two car loans, and these are not listed as

liabilities.

Do you have an ethical dilemma? Discuss your approach to handling

this situation.

• In manufacturing:

• all materials costs that are easily traced to the product are called

direct material costs

• all labor costs that are easily traced to the product are called direct

labor costs

• all other production costs are called overhead costs

• Whether or not a cost is a direct cost depends upon:

• the definition of the cost object

• the precision of the bookkeeping system that tracks costs

• the technology available to capture cost information

• whether the benefits of tracking the cost as direct exceed the

resources expended to track the cost

• the nature of the operations that produce the product or service

Q1: Linear Cost Behavior Terminology

• Total fixed costs are costs that do not change (in

total) as activity levels change.

• Total variable costs are costs that increase (in total)

in proportion to the increase in activity levels.

• Total costs equal total fixed costs plus total variable

costs.

• The relevant range is the span of activity levels for

which the cost behavior patterns hold.

• A cost driver is a measure of activity or volume

level; increases in a cost driver cause total costs to

increase.

Q1: Cost Terms for Decision Making

• In Chapter 1 we learned the distinction between

relevant and irrelevant cash flows.

• Opportunity costs are the benefits of an alternative

one gives up when that alternative is not chosen.

• Opportunity costs are difficult to measure because they

are associated with something that did not occur.

• Opportunity costs are always relevant in decision

making.

• Sunk costs are costs that were incurred in the past.

• Sunk costs are never relevant for decision making.

Q1: Cost Terms for Decision Making

• Discretionary costs are periodic costs incurred for

activities that management may or may not

determine are worthwhile.

• These costs may be variable or fixed costs.

• Discretionary costs are relevant for decision making

only if they vary across the alternatives under

consideration.

• Marginal cost is the incremental cost of producing

the next unit.

• When costs are linear and the level of activity is within

the relevant range, marginal cost is the same as

variable cost per unit.

• Marginal costs are often relevant in decision making.

Q2: What Process is Used to Estimate

Future Costs?

Past costs are often used to estimate future,

non-discretionary, costs. In these instances,

one must also consider:

• whether the past costs are relevant to the

decision at hand

• whether the future cost behavior is likely to

mimic the past cost behavior

• whether the past fixed and variable cost

estimates are likely to hold in the future

kayaks would estimate some of the following:

• the amount and cost of the rubber required

• the amount and cost of labor required in the cutting department

•

Q3: Account Analysis Method of

Estimating a Cost Function

• Review past costs in the general ledger and past

activity levels to determine each cost’s past

behavior.

• For example, a company producing clay wine

goblets might review its records and find:

• the cost of clay is piecewise linear with respect to the number of

pounds of clay purchased

• skilled production labor is variable with respect to the number of

goblets produced

Q3: Two-Point Method of

Estimating a Cost Function

• Use the information contained in two past

observations of cost and activity to separate

mixed and variable costs.

• It is much easier and less costly to use than the

account analysis or engineered estimate of cost

methods, but:

• it estimates only mixed cost functions,

• it is not very accurate, and

• it can grossly misrepresent costs if the data points

come from different relevant ranges of activity

Q3: Example – Two-Point Method of

Estimating a Cost Function

In July the Gibson Co. incurred total overhead costs of $58,000 and

made 6,200 units. In December it produced 3,200 units and total

overhead costs were $40,000. What are the total fixed factory costs per

month and average variable factory costs?

We first need to determine V, using the equation for the slope of a line.

$

rise/run = $58,000 – $40,000

6,200 – 3,200 units

= $18,000/3,000 units

= $6/unit

Then, using TC = F + V x Q, and one

of the data points, determine F.

$58,000

$58,000 = F + $6/unit x 6,200 units

$40,000

$58,000 = F + $37,200

$20,800

be representative of costs in the relevant

range

• this method may underestimate total fixed costs

and overestimate variable costs per unit,

Q5: How is Regression Analysis Used to

Estimate a Mixed Cost Function?

• Regression analysis estimates the parameters for a linear

relationship between a dependent variable and one or more

independent (explanatory) variables.

• When there is only one independent variable, it is called

simple regression.

• When there is more than one independent variable, it is

called multiple regression.

Q5: Regression Output Terminology:

p-value and t-statistic.

• The t-statistic and the p-value both measure our

confidence that the true coefficient is non-zero.

• In general, if the t-statistic for the intercept (slope) term

> 2, we can be about 95% confident (at least) that the

true intercept (slope) term is not zero.

• The p-value is more precise

• it tells us the probability that the true coefficient

being estimated is zero

• if the p-value is less than 5%, we are more than

95% confident that the true coefficient is non-zero.

• The future is always unknown, so there are

uncertainties when estimating future costs.

• The estimated cost function may have misspecified the cost behavior.

• The cost function may be using an incorrect cost

driver.

• Future cost behavior may not mimic past cost

behavior.

• Future costs may be different from past costs.

Q6: Considerations When Using

Estimates of Future Costs

• The data used to estimate past costs may not be of

high-quality.

• The accounting system may aggregate costs in a

way that mis-specifies cost behavior.

• Information from outside the accounting system

may not be accurate.

• The true cost function may not be in agreement

with the cost function assumptions.

• For example, if variable costs per unit of the cost

driver are not constant over any reasonable

range of activity, the linearity of total cost

assumption is violated.

A learning curve is

• the rate at which labor hours per unit decrease as the

volume of activity increases

• the relationship between cumulative average hours per

unit and the cumulative number of units produced.

A learning curve can be represented mathematically as:

Y = α Xr, where

Y = cumulative average labor hours,

α = time required for the first unit,

X = cumulative number of units produced,

r = an index for learning = ln(% learning)/ln(2), and

ln is the natural logarithmic function.

Suppose that Bill’s marketing department says that he can sell 6,000

briefcases if the selling price is reduced to $170. Bill’s target pretax

profit is $210,000. Determine the highest level that his variable costs

can so that he can make his target. Recall that F = $360,000.

Use the CVP formula for units, but solve for V:

commission for sales persons

• highly automated production process with low variable

costs per unit vs. lower technology process with higher

variable costs per unit and lower fixed costs.

• broad advertising campaign with higher selling prices vs.

minimal advertising and lower selling prices

Q1,2: Using CVP to Compare Alternatives

Currently Bill’s salespersons have salaries totaling $80,000 (included

in F of $360,000) and earn a 5% commission on each unit ($10 per

briefcase). He is considering an alternative compensation arrangement

where the salaries are decreased to $35,000 and the commission is

increased to 20% ($40 per briefcase). Compute the BEP in units under

the proposed alternative. Recall that P = $200 and V = $80 currently.

First compute F and V under the proposed plan:

F = $360,000 – $45,000 decrease in salaries = $315,000

V = $80 + $30 increase in commission = $110

Then compute Q under the proposed plan:

Q4: Assumptions in CVP Analysis

CVP analysis assumes that costs and revenues are

linear within a relevant range of activity.

• Linear total revenues means that selling prices per unit

are constant and the sales mix does not change.

• Offering volume discounts to customers violates this assumption.

• Linear total costs means total fixed costs are constant

and variable costs per unit are constant.

• If volume discounts are received from suppliers, then

variable costs per unit are not constant.

• If worker productivity changes as activity levels change,

then variable costs per unit are not constant.

Q4: Assumptions in CVP Analysis

• These assumptions may induce a small relevant

range.

• Results of CVP calculations must be checked to see if

they fall within the relevant range.

• Linear CVP analysis may be inappropriate if the

linearity assumptions hold only over small ranges

of activity.

• Nonlinear analysis techniques are available.

• For example, regression analysis, along with nonlinear

transformations of the data, can be used to estimate

nonlinear cost and revenue functions.

• The degree of operating leverage shows the

sensitivity of profits to changes in sales.

• On the prior slide Bill’s degree of operating leverage

was 2.5 and profits were $240,000.

• If expected sales were to increase to 6,000 units,

a 20% increase, then profits would increase by

2.5 x 20%, or 50%, to $360,000.*

• If expected sales were to decrease to 4,500 units,

a 10% decrease, then profits would decrease by

2.5 x 10%, or 25%, to $180,000.**

* $240,000 x 1.5 = $360,000

Q2: Special Order Decisions

Suppose that the capacity of RobotBits is 107,000 units and projected

sales to regular customers this year total 94,000 units. Does the

quantitative analysis suggest that the company should accept the

special order?

First determine if there is sufficient idle capacity to accept this

order without disrupting normal operations:

Projected sales to regular customers

Special order

94,000 units

8,000 units

102,000 units

RobotBits still has 5,000 units of idle capacity if the order is

accepted. Compare incremental revenue to incremental cost:

Incremental profit if accept special order =

($24 selling price – $20 relevant costs) x 8,000 units = $32,000

Q2: Qualitative Factors in

Special Order Decisions

What qualitative issues, in general, might RobotBits consider before

finalizing its decision?

• Will USR expect the same selling price per unit on future

orders?

• Will other regular customers be upset if they discover the

lower selling price to one of their competitors?

• Will employee productivity change with the increase in

production?

• Given the increase in production, will the incremental costs

remain as predicted for this special order?

• Are materials available from its supplier to meet the increase

in production?

Q2: Special Order Decisions and Capacity Issues

Suppose instead that the capacity of RobotBits is 100,000 units and

projected sales to regular customers this year totals 94,000 units.

Should the company accept the special order?

Here the company does not have enough idle

capacity to accept the order:

Projected sales to regular customers

Special order

94,000 units

8,000 units

102,000 units

If USR will not agree to a reduction of the order to 6,000

units, then the offer can only be accepted by denying sales

of 2,000 units to regular customers.

Variable cost/unit for

regular sales = $22.50.

CM/unit on regular sales

= $38.00 – $22.50 = $15.50.

The opportunity cost of accepting this

order is the lost contribution margin

on 2,000 units of regular sales.

Incremental profit if accept special order =

$32,000 incremental profit under idle capacity – opportunity cost =

$32,000 – $15.50 x 2,000 = $1,000

Q2: Qualitative Factors in

Special Order Decisions

What additional qualitative issues, in this case of a capacity constraint,

might RobotBits consider before finalizing its decision?

• What will be the effect on the regular customer(s) that do not

receive their order(s) of 2,000 units?

• What is the effect on the company’s reputation of leaving

orders from regular customers of 2,000 units unfilled?

• Will any of the projected costs change if the company

operates at 100% capacity?

• Are there any methods to increase capacity? What effects do

these methods have on employees and on the community?

• Notice that the small incremental profit of $1,000 will probably

be outweighed by the qualitative considerations.

Q3: Keep or Drop Decisions

•

Managers must determine whether to keep or

eliminate business segments that appear to be

unprofitable.

•

The general rule for keep or drop decisions is:

•

•

keep the business segment if its contribution margin

covers its avoidable fixed costs,

subject to qualitative considerations.
