Product Costing and Transfer Prices –
Butyl rubbers were costed using standard
rates for variable and fixed costs.
Variable costs included feedstocks, chemicals, and
energy. Standard variable cost per ton of butyl was
calculated by multiplying the standard utilization factor
(i.e., the standard quantity of inputs used) by a standard
price established for each unit of input. Since feedstock
prices varied with worldwide market conditions and
represented the largest component of costs, it was
impossible to establish standard input prices that
remained valid for extended periods. Therefore, the
company reset standard costs each month to a price that
reflected market prices. Chemical and energy standard
costs were established annually.

1b) Interpret the amount $22,589 on
Exhibit 2, for variable costs.
The $22,589 is in the “actual” column, and is the
variable cost
at standard
. Therefore, it is based
on the actual volume of output (i.e., sales), but
uses the budgeted cost of the inputs (feedstocks,
chemicals, and energy) per ton of output.
The standard cost per ton for raw materials,
averaged over the 9 months,was $631 per ton
($22,589/35.8).
The $22,589 is equivalent to a flexible budget
amount. It is the answer to the question: What
should our input costs have been for our actual
level of output (sales)?

1c) Interpret the amount
$21,450 on Exhibit 2, for
variable costs.
This is the static budget number for variable
costs (feedstocks, chemicals, energy). Since it
is the static budget, it is based on the original,
projected level of sales. From Exhibit 1, the
projected level of sales was 33,000 tons.
Hence, the standard cost per ton for variable
costs, as of the beginning of the year, was $650
per ton ($21,450/33).
How can the standard cost per ton
for variable costs differ from the
beginning of the year to the end of
the year?
I.e.: $650 per ton vs. $631 per ton.

• Sales price per ton is slightly below budget.
• Sales volume is almost 10% above budget.
• The efficiency variance for variable costs is very small.
• The price variance for variable costs is very small, due in part
to the fact that standards are revised monthly.
• Fixed manufacturing expenses are within 2% of budget.
• Non-manufacturing expenses are within 1% of budget.

Does Polysar close out variances to
Cost of Goods Sold, or allocate
variances between Cost of Goods Sold
and Inventory?
POLYSAR
In the previous question, we were able to
recalculate the fixed cost component of butyl
added to ending inventory, and butyl transferred
to EROW, using the budgeted $700 per ton rate.
Therefore, no variances are included in these
amounts, and all variances closed out to the
income statement (Exhibit 2). These variances
appear on the line items for “Cost Adjustments,”
“Spending Variance,” and “Volume Variance.”

5.
Using the information on Exhibit 1,
identify EROW’s rate for applying fixed
manufacturing costs to Butyl.
What
might explain the difference in
the
fixed overhead rates of the two
divisions?
POLYSAR
From the Budgeted column on Exhibit 1,
we know that NASA planned to take 1K
tonnes of butyl from EROW, at a cost
(i.e., fixed cost component) of $620K, or
$620 per ton.
EROW’s fixed cost rate of $620 is lower
than NASA’s rate of $700, probably
because EROW’s facility is older. Note
that the difference in rates cannot be due
to differences in capacity utilization.

Transfer Pricing Options
• Market-Based Transfer Price
• Cost-Based Transfer Price
• Negotiated Transfer Price
• Dual Transfer Price
Product Costing and Transfer Prices –
… Product transfers between divisions for
performance accounting purposes were
made at standard full cost, representing,
for each ton, the sum of standard variable
cost and standard fixed cost.
POLYSAR
• Polysar uses a cost-based transfer
price.
COST-BASED TRANSFER PRICE
• Can be variable cost or full cost.
• Whether variable or full, can be
actual costs or budgeted costs.
• Whether variable or full, can
include a “mark-up” to allow profit
for the “selling” division.
POLYSAR
Interview with Pierre Choquette (Vice
President of NASA Rubber Division) –
“Our transfers to EROW are still a problem. Since
the transfers are at standard cost and are not
recorded as revenue, these transfers do nothing
for our profit. Also, if they cut back on orders,
our profit is hurt through the volume variance.
Few of our senior managers truly understand the
volume variance.
POLYSAR
• Polysar uses a cost-based transfer price.
• It is a full cost transfer price (i.e., it
includes both variable and fixed costs).
• It is based on budgeted (i.e., standard
costs).
POLYSAR
8b. What is the transfer price for
butyl?
Product Costing and Transfer Prices –
… Fixed costs were allocated to production based
on a plant’s “demonstrated capacity” using the
following formula,
standard fixed cost per ton =
estimated annual total fixed cost ÷
annual demonstrated plant capacity
To apply the formula, product estimates were
established each fall for the upcoming year.
Exhibit 5
POLYSAR
LIM
ITED – CONTROLLER’S GUIDE
DEFINITIONS
Demonstrated capacity
is the actual annualized production of a plant which was
required to run full out within the last fiscal year for a sufficiently long period to
assess production capability after adjusting for abnormally low or high unscheduled
shutdowns, scheduled shutdowns, and unusual or annualized items which impacted
either favourably
or unfavourably
on the period’s production. The resulting
adjusted historical base should be further modified for changes planned to be
implemented within the current fiscal year.
a)
Where a plant has not been required to run full out within the last fiscal
year, production data may be used for a past period afer adjusting for
changes (
debottleneckings
/inefficiencies) since that time affecting
production.
b)
Where a plant has never been required to run full out, demonstrated
capacity could be reasonably considered as “name plate” capacity after
adjusting for
i)
known invalid assumptions in arriving at “name plate”
ii)
changes to original design affecting “name plate”
iii)
a reasonable negative allowance for error
CALCULATION OF TRANSFER
PRICE FOR BUTYL
Total Fixed Costs were budgeted at $44,625K
(from Exhibit 1).
Denominator is “demonstrated capacity.” This is
85,000 tons per year, or 63,750 tonnes for 9
months.
POLYSAR
8c. What is the effect on NASA when
EROW takes less butyl than
planned, if NASA produces for
actual demand?
POLYSAR
Each ton of butyl transferred to EROW has
$700 in fixed costs attached to it. EROW
covers $700 of NASA’s fixed costs with
each ton “purchased” from NASA.
When EROW takes less butyl than
planned, and NASA cuts back on
production accordingly, NASA’s volume
variance increases, and its net
contribution (i.e., income) decreases,
relative to plan.
POLYSAR
8d. What is the effect on NASA when
EROW takes less butyl than
planned, if NASA produces for
budgeted demand?
POLYSAR
If NASA produces at budgeted demand, and EROW purchases less butyl than planned,
NASA will increase its ending inventory.
In this case, the fact that EROW takes less butyl than planned will have no effect on
NASA’s net contribution. The $700 per ton in fixed costs that NASA thought would be
covered by EROW, will now be capitalized in ending inventory.
POLYSAR
8c. What is the best butyl sourcing
strategy for Polysar?
POLYSAR
Polysar should allocate production of butyl and halobutyl to EROW
and NASA to minimize total production and shipping costs, while
still meeting customer demand.
In making this determination, fixed costs are
irrelevant, since they are either sunk costs, or are
unavoidable unless the plant is closed down.
Polysar should manufacture butyl as long as the
sales price is more than the variable costs of
Product Costing and Transfer Prices –
… Fixed costs comprised three categories of cost.
Direct costs included direct labor, maintenance,
chemicals required to keep the plant bubbling,
and fixed utilities. Allocated cash costs included
plant management, purchasing department costs,
engineering, planning, and accounting. Allocated
non-cash costs represented primarily

8f. What is the best butyl sourcing
strategy for EROW, given the
current accounting treatment,
and the bonus scheme?
POLYSAR
From EROW’s point of view, the $700 per
tonne allocation of fixed costs is a
variable cost. If EROW can manufacture
an extra ton of butyl in Antwerp, instead
of buying the butyl from NASA, EROW
saves $700.
EROW should manufacture as much butyl
in Antwerp as possible, before buying
POLYSAR
If EROW can sell one more ton of butyl,
at a price equal to NASA’s variable costs,
plus shipping, plus $699, will they want
to?
In the above situation, will the company
want EROW to make the sale?
POLYSAR
Compensation
Management –
For managers, the percent of remuneration
received through annual bonuses was greater
than 12% and increased with responsibility
levels.
The bonuses of top Division management in 1985
were calculated by a formula that awarded
50%
of bonus potential to meeting or exceeding
Divisional profit targets
and 50% to meeting or
exceeding corporate profit targets.
POLYSAR
Product Scheduling
Although NASA served customers in North and South
America and EROW served customers in Europe and the
rest of the world, regular butyl could be shipped from
either the Sarnia 2 or Antwerp plant. NASA shipped
approximately 1/3 of its regular butyl output to EROW.
Also, customers located in distant locations could receive
shipments from either plant due to certain cost or
logistical advantages. For example, Antwerp sometimes
shipped to Brazil and Sarnia sometimes shipped to the
Far East. …
POLYSAR
Product Scheduling
… In September and October of each year, NASA and
EROW divisions prepared production estimates for the
upcoming year. These estimates were based on estimated
sales volumes and plant loadings (i.e., capacity
utilization). Since the Antwerp plant operated at capacity,
the planning exercise was largely for the benefit of the
managers of the Sarnia 2 plant, who needed to know how
much regular butyl Antwerp would need from the Sarnia
2 plant.
POLYSAR
What are EROW’s incentives in the
budgeting process?
What happens if EROW estimates
greater demand for butyl than EROW
actually needs?
