Professor Anthony Atkinson, (University of Waterloo) and adapted by Professor John Shank (The Amos Tuck School of Business Administration Dartmouth College) This case is reprinted from Cases in Cost Management, Shank, J. K., 1996, South Western Publishing Company. The case was adapted by Professor John Shank, with permission from the author from an earlier case written by Professor Anthony Atkinson under a grant from the Society of Management Accountants of Canada. The case was originally set in the mid-1980s. In September of 2017 Michael Smith, Division Manager of Brunswick Plastics, faced an important pricing decision on a major new bid opportunity. Michael knew that pricing too high meant losing a bid that would employ currently unused capacity. On the other hand, pricing too low meant losses on the job. In the first two months after Michael arrived in November of 2015, the presses were running only about 40 per cent of available machine hours. The division had recently lost two large contracts and was struggling to find a solid market position. Michael had instituted a policy of ‘contribution margin pricing’ to restore profitability. He reasoned that the fixed costs were already in place and there was heavy excess capacity. Any orders that generated positive contribution would enhance bottom line profits. In two years, machine running time was up to almost 50 per cent of available machine hours and the number of different products manufactured was up from 30 to 50. THE COMPANY In addition to the 50 different products BP was selling, it was also typically experimenting in the factory with a few others at any given time. New product introductions seemed to Michael to be a key step in filling up the factory. Smith’s best estimate of sales for 2017 was $1 200 000 and he thought BP would again be just above the breakeven level on profits. An estimated income statement for 2017 is shown in Exhibit 1. The division had 20 full-time employees. Since the factory was not unionised, the factory employment fluctuated monthly, based on demand. Factory employment had ranged between 13 and 31 people in the past 2 ½ years. Through strict attention to quality control, and by aggressively promoting its products, BP products were specified by major customers and had become the industry standard for quality. BP sold its products in both domestic and US markets and faced a highly competitive environment. There were many injection moulding companies in eastern Canada and the northeastern part of the USA. As a result, pricing was a key to success, both from the point of view of securing contracts, and from the point of view of profitability. Manufacturing at EP was done in two different modes. Some of the high-volume products were manufactured to stock in long runs to minimize set-up costs and to maintain required inventory levels. However, for most products, production was in response to a specific order. THE COSTING ENVIRONMENT There were five major injection moulding presses in use at BP. The machines were of varying ages and all experienced frequent down-time because of set-ups, raw material problems, regular repairs, and special repairs related to complex products or new product problems. The factory typically operated 2 shifts a day, 5 days a week, but volume fluctuations also led sometimes to one shift or three shift operations. There were four common stages involved in manufacturing a product: (1) set up of the production machine, (2) the production operation, (3) the assembly operation, and (4) the testing operation. The setup, assembly, and the testing operations were labour-intensive. The labour content of the production operation varied widely from product to product. In injection moulding, molten plastic is forced into a mould where it is ‘cured’. The curing process requires cooling the mould, usually with water. Once the product has cured, the mould is opened and the product is removed. Some products were produced in stationary moulds that required little manual intervention. Water has passed through these moulds during the curing cycle. At the completion of the curing cycle, the moulds were opened and the products ejected automatically. For these products, the direct labour content was minimal and the operation was machine-paced. Other products were produced in removable moulds that required manual intervention. After the plastic was injected, these moulds were removed from the moulding machine and placed into a vat of water for the curing cycle. At the completion of the curing cycle, the moulds were opened manually and the product removed. For these products, the direct labour content could be significant since the operation was labour-paced. The products also varied widely in terms of assembly and testing time required. On the one hand, the company manufactured paediatric syringes used in the care of premature infants. These syringes required extensive attention to quality control and a considerable amount of manual assembly in a ‘clean room’. On the other hand, the company also manufactured wheel chocks that required only a cursory inspection and no assembly. The other products produced by BP varied between these two extremes. In addition to the product costing complications caused by the wide mix of manufacturing, assembly and testing requirements, there were difficulties caused by the machines. Typical of the industry, the machines used at BP differed widely in terms of their reliability and their performance when producing different products. A machine problem meant that the machine would have to be stopped and reset. Because the machine stoppages were highly unpredictable, incorporating a normal or average machine failure cost into the product cost was difficult. On the other hand, the materials, assembly and testing costs of most products were well understood since each of these costs could be measured with reasonable accuracy. Materials costs could be estimated by the weight of the final product since the materials in most defective products could be reused. The assembly and testing operations involved the use of machines that were both highly reliable and labour- paced. These difficulties and the costing issues were all on Michael’s mind as he considered the milk crate contract. THE MILK CRATE CONTRACT Dairies in eastern Canada used plastic crates to ship milk cartons from the dairies to the stores. The annual sales volume of milk crates in the local region was about 30 000 units. Dairies merged their orders for crates through the Dairy Council in order to take maximum advantage of possible quantity discounts. Michael had been asked to submit a bid on an initial order of 150 000 units. It was clear in Michael’s mind that a successful initial bid would give BP a competitive advantage in future orders. Michael felt that the successful bid price for these crates would be ‘$3.00 plus or minus ten cents. Michael had been approached by the customer several times and felt that BP’s reputation for quality would ensure that a $3.00 bid would be successful. As a result, estimating the bid price was not the major issue. The question to be resolved was whether or not, given its cost structure, $3.00 could cover BP’s cost for producing this product. Discussions with Walt Roberts and Larry Bobbit, BP’s technical and production supervisors, suggested that the machine cycle time to produce this product would be 50 seconds per unit. The product would be produced in a stationary mould and would be automatically ejected at the rate of one every 50 seconds. As a result, Michael calculated that it would require 20831 hours of machine running time to fill the order. On the basis of his discussion with Walt Roberts, Michael expected that the rate of defective crates produced by this process would be negligible. Following discussions with Larry Bobbit, Michael felt that during the machine cycle the time machine operator would have sufficient time to trim the excess plastic (flash) off the previous crate that had been made and stamp that crate with the particular dairy’s name. Based on BP’s experience, which was comparable to the industry average, Michael calculated that the moulding machine would run for only 60 per cent of the time that it was scheduled for operation. The rest of the time that it was scheduled for operation the machine would be down for repair, set-up or maintenance. Consequently, Michael estimated that it would require 34722 hours of scheduled machine time to achieve the required 2083 hours of machine operating time. Since the operator would be required for most of the repair time, all the set-up time, and all the maintenance time, an operator would have to be scheduled for each hour of scheduled machine time. Michael decided that the production of the milk crates would be undertaken on BP’s 750-ton injection moulder. This would require that some of the production scheduled for that be rescheduled to other machines. Because BP currently had excess capacity available on other machines, Michael felt that the new order would not require sacrificing any production of any other products. The cost of a production mould used to manufacture the milk crates would normally be $90 000. However, the Diary Council already owned a suitable mould which they had agreed to lend to the successful bidder on the contract. Each milk crate weighed 1.6 kilograms. Polyethelene would be used to produce the milk crate. The cost of polyethylene was $1.07 per kilogram. Michael felt that plastic trimmed off crates, or plastic in defective crates, could be reprocessed at a minimal cost. Consequently, the cost of raw material per crate was estimated as $1.71.3 Since the machine operators were paid $6.00 per hour (including benefits), the labour cost per crate was computed at $0.14.4 The materials cost to stamp the crates was estimated as $0.01 per side, yielding a total cost of $0.04 per crate. In addition, a stamping machine costing $5000 would have to be acquired. The life of this simple stamping machine was estimated as 10 years, at least. The crates did not require packaging for shipping and the Dairy Council paid for shipment. Michael estimated that the labour costs to load the crates on a truck at the factory door would be $0.02 per crate. As a result of these calculations, Michael believed that the direct variable cost of producing the milk crates would be $1.91 (1.71 + .14 + .04 + 02). This still left the matter of the overhead associated with producing each milk crate. This issue had been a source of continuing concern to Michael on almost every contract he negotiated. Michael knew that a common ‘rule of thumb’ in his plant was to apply variable overhead to products at a rate of $13 for each machine hour (running time). An industry rule of thumb was to estimate total variable cost as being 1.3 times the direct material and direct labour costs5. Some analysts also advocated looking at fixed, as well as variable, manufacturing overhead. Based on a recent study of BP’s costs, the corporate controller estimated that, on average, selling price must equal at least 2.33 times the sum of direct material and direct labour costs in order to earn average industry margins of 6 per cent (pre-tax) when operating at the industry average 90 per cent capacity utilization ratio (scheduled hours). Some comparative data on industry economics is summarized in Exhibit 2. Michael wondered about the accuracy of any of these approaches in general and, in particular, he wondered if anyone was suitable in this situation. Michael looked at the ratio market price to the sum of direct material and direct labour cost for some of his more popular products and found that this ratio varied from two to seven. As a result, he wondered what, if anything, was the implication of the 2.33 factor. As a guide to understanding the relationship between direct costs (material and labour) and fixed manufacturing overhead Michael developed the data that appear in Exhibit 3. The plant accountant advised Michael that plant fixed manufacturing overhead did not include direct materials, direct labour, variable overhead or plant supervision (about $50 000 per year). In addition to manufacturing costs, BP was incurring about $220 000 per year in Selling, General and Administrative (S, G & A) expenses. Michael was not sure how to use Exhibit 3 to help him assign overhead cost to the milk crate order. The results did seem to indicate that overhead was virtually unrelated to the level of output in the factory. The results thus did seem to support ‘contribution margin pricing’ policy. Michael was still unsure, however, as to how he should approach this large incremental order. He observed to the case writer: ‘If I only knew my cost structure better, I would feel more confident about what I’m doing. Right now I feel that I am shooting in the dark.’ When operating near capacity, BP shows up as the High CM/High fixed cost/high profit player. But note that the profit impact (Profit % of Sales) of BP’s apparent strategy only shows up near full capacity. High volume is a key to high profit for BP.

To explore the casual relationships reflected here, Michael developed the following four linear regressions:


QUESTIONS:

1. Based on your interpretation of Exhibit 3, what is your estimate of the change in ‘PFMOH’ cost if the factory was to run one extra batch of 150 000 milk crates?
2. What is your estimate of the incremental cost per unit for one batch of 150 000 milk crates?
3. What does Exhibit 2 suggest would be a ‘normal’ price for milk crates for an ‘average’ job shop? What does this suggest about the $3.00 price which seems to prevail at the time of the case?
4. What is the ‘strategically relevant’ cost per unit for milk crates (for purposes of deciding whether or not the $3.00 ‘market price’ is profitable, on an ongoing basis)?
5. What is your advice to Mr Smith regarding the milk crate opportunity? Be specific and show the calculations supporting your advice.
6. What overall strategic advice do you have for Mr Smith? Why isn’t the business doing better, given the new ‘specialities strategy’ and good business conditions? Support your answer with relevant cost analysis.

Michael estimated that the labour costs to load the crates on a truck at the factory door would be $0.02 per crate. As a result of these calculations, Michael believed that the direct variable cost of producing the milk crates would be $1.91 (1.71 + .14 + .04 + 02).
This still left the matter of the overhead associated with producing each milk crate. This issue had been a source of continuing concern to Michael on almost every contract he negotiated. Michael knew that a common ‘rule of thumb’ in his plant was to apply variable overhead to products at a rate of $13 for each machine hour (running time). An industry rule of thumb was to estimate total variable cost as being 1.3 times the direct material and direct labour costs5.
Some analysts also advocated looking at fixed, as well as variable, manufacturing overhead. Based on a recent study of BP’s costs, the corporate controller estimated that, on average, selling price must equal at least 2.33 times the sum of direct material and direct labour costs in order to earn average industry margins of 6 per cent (pre-tax) when operating at the industry average 90 per cent capacity utilization ratio (scheduled hours). Some comparative data on industry economics is summarized in Exhibit 2.
Michael wondered about the accuracy of any of these approaches in general and, in particular, he wondered if anyone was suitable in this situation. Michael looked at the ratio market price to the sum of direct material and direct labour cost for some of his more popular products and found that this ratio varied from two to seven. As a result, he wondered what, if anything, was the implication of the 2.33 factor.
As a guide to understanding the relationship between direct costs (material and labour) and fixed manufacturing overhead Michael developed the data that appear in Exhibit 3. The plant accountant advised Michael that plant fixed manufacturing overhead did not include direct materials, direct labour, variable overhead or plant supervision (about $50 000 per year).
In addition to manufacturing costs, BP was incurring about $220 000 per year in Selling, General and Administrative (S, G & A) expenses. Michael was not sure how to use Exhibit 3 to help him assign overhead cost to the milk crate order. The results did seem to indicate that overhead was virtually unrelated to the level of output in the factory. The results thus did seem to support ‘contribution margin pricing’ policy. Michael was still unsure, however, as to how he should approach this large incremental order. He observed to the case writer: ‘If I only knew my cost structure better, I would feel more confident about what I’m doing. Right now I feel that I am shooting in the dark.’ When operating near capacity, BP shows up as the High CM/High fixed cost/high profit player. But note that the profit impact (Profit % of Sales) of BP’s apparent strategy only shows up near full capacity. High volume is a key to high profit for BP.




To explore the casual relationships reflected here, Michael developed the following four linear regressions:

This case is reprinted from Cases in Cost Management, Shank, J. K., 1996, South Western Publishing Company. The case was adapted by Professor John Shank, with permission from the author from an earlier case written by Professor Anthony Atkinson under a grant from the Society of Management Accountants of Canada. The case was originally set in the mid-1980s.
In September of 2017 Michael Smith, Division Manager of Brunswick Plastics, faced an important pricing decision on a major new bid opportunity. Michael knew that pricing too high meant losing a bid that would employ currently unused capacity. On the other hand, pricing too low meant losses on the job. In the first two months after Michael arrived in November of 2015, the presses were running only about 40 per cent of available machine hours. The division had recently lost two large contracts and was struggling to find a solid market position. Michael had instituted a policy of ‘contribution margin pricing’ to restore profitability. He reasoned that the fixed costs were already in place and there was heavy excess capacity. Any orders that generated positive contribution would enhance bottom line profits. In two years, machine running time was up to almost 50 per cent of available machine hours and the number of different products manufactured was up from 30 to 50.
THE COMPANY
In addition to the 50 different products BP was selling, it was also typically experimenting in the factory with a few others at any given time. New product introductions seemed to Michael to be a key step in filling up the factory. Smith’s best estimate of sales for 2017 was $1 200 000 and he thought BP would again be just above the breakeven level on profits. An estimated income statement for 2017 is shown in Exhibit 1. The division had 20 full-time employees. Since the factory was not unionised, the factory employment fluctuated monthly, based on demand. Factory employment had ranged between 13 and 31 people in the past 2 ½ years. Through strict attention to quality control, and by aggressively promoting its products, BP products were specified by major customers and had become the industry standard for quality.
BP sold its products in both domestic and US markets and faced a highly competitive environment. There were many injection moulding companies in eastern Canada and the northeastern part of the USA. As a result, pricing was a key to success, both from the point of view of securing contracts, and from the point of view of profitability.
Manufacturing at EP was done in two different modes. Some of the high-volume products were manufactured to stock in long runs to minimize set-up costs and to maintain required inventory levels. However, for most products, production was in response to a specific order.
THE COSTING ENVIRONMENT
There were five major injection moulding presses in use at BP. The machines were of varying ages and all experienced frequent down-time because of set-ups, raw material problems, regular repairs, and special repairs related to complex products or new product problems. The factory typically operated 2 shifts a day, 5 days a week, but volume fluctuations also led sometimes to one shift or three shift operations.
There were four common stages involved in manufacturing a product: (1) set up of the production
 machine, (2) the production operation, (3) the assembly operation, and (4) the testing operation. The setup, assembly, and the testing operations were labour-intensive. The labour content of the production operation varied widely from product to product.
In injection moulding, molten plastic is forced into a mould where it is ‘cured’. The curing process requires cooling the mould, usually with water. Once the product has cured, the mould is opened and the product is removed.
Some products were produced in stationary moulds that required little manual intervention. Water has passed through these moulds during the curing cycle. At the completion of the curing cycle, the moulds were opened and the products ejected automatically. For these products, the direct labour content was minimal and the operation was machine-paced.
Other products were produced in removable moulds that required manual intervention. After the plastic was injected, these moulds were removed from the moulding machine and placed into a vat of water for the curing cycle. At the completion of the curing cycle, the moulds were opened manually and the product removed. For these products, the direct labour content could be significant since the operation was labour-paced.
The products also varied widely in terms of assembly and testing time required. On the one hand, the company manufactured paediatric syringes used in the care of premature infants. These syringes required extensive attention to quality control and a considerable amount of manual assembly in a ‘clean room’.
On the other hand, the company also manufactured wheel chocks that required only a cursory inspection and no assembly. The other products produced by BP varied between these two extremes.
In addition to the product costing complications caused by the wide mix of manufacturing, assembly and testing requirements, there were difficulties caused by the machines. Typical of the industry, the machines used at BP differed widely in terms of their reliability and their performance when producing different products. A machine problem meant that the machine would have to be stopped and reset.
Because the machine stoppages were highly unpredictable, incorporating a normal or average machine failure cost into the product cost was difficult.
On the other hand, the materials, assembly and testing costs of most products were well understood since each of these costs could be measured with reasonable accuracy. Materials costs could be estimated by the weight of the final product since the materials in most defective products could be reused. The assembly and testing operations involved the use of machines that were both highly reliable and labour- paced. These difficulties and the costing issues were all on Michael’s mind as he considered the milk crate contract.
THE MILK CRATE CONTRACT
Dairies in eastern Canada used plastic crates to ship milk cartons from the dairies to the stores. The annual sales volume of milk crates in the local region was about 30 000 units. Dairies merged their orders for crates through the Dairy Council in order to take maximum advantage of possible quantity discounts.
Michael had been asked to submit a bid on an initial order of 150 000 units. It was clear in Michael’s mind that a successful initial bid would give BP a competitive advantage in future orders.
Michael felt that the successful bid price for these crates would be ‘$3.00 plus or minus ten cents. Michael had been approached by the customer several times and felt that BP’s reputation for quality would ensure that a $3.00 bid would be successful. As a result, estimating the bid price was not the major issue. The question to be resolved was whether or not, given its cost structure, $3.00 could cover BP’s cost for producing this product.
Discussions with Walt Roberts and Larry Bobbit, BP’s technical and production supervisors, suggested that the machine cycle time to produce this product would be 50 seconds per unit. The product would be produced in a stationary mould and would be automatically ejected at the rate of one every 50 seconds. As a result, Michael calculated that it would require 20831 hours of machine running time to fill the order. On the basis of his discussion with Walt Roberts, Michael expected that the rate of defective crates produced by this process would be negligible.
Following discussions with Larry Bobbit, Michael felt that during the machine cycle the time machine operator would have sufficient time to trim the excess plastic (flash) off the previous crate that had been made and stamp that crate with the particular dairy’s name. Based on BP’s experience, which was comparable to the industry average, Michael calculated that the moulding machine would run for only 60 per cent of the time that it was scheduled for operation. The rest of the time that it was scheduled for operation the machine would be down for repair, set-up or maintenance.
Consequently, Michael estimated that it would require 34722 hours of scheduled machine time to achieve the required 2083 hours of machine operating time. Since the operator would be required for most of the repair time, all the set-up time, and all the maintenance time, an operator would have to be scheduled for each hour of scheduled machine time. Michael decided that the production of the milk crates would be undertaken on BP’s 750-ton injection moulder. This would require that some of the production scheduled for that be rescheduled to other machines. Because BP currently had excess capacity available on other machines, Michael felt that the new order would not require sacrificing any production of any other products. The cost of a production mould used to manufacture the milk crates would normally be $90 000. However, the Diary Council already owned a suitable mould which they had agreed to lend to the successful bidder on the contract.
Each milk crate weighed 1.6 kilograms. Polyethelene would be used to produce the milk crate. The cost of polyethylene was $1.07 per kilogram. Michael felt that plastic trimmed off crates, or plastic in defective crates, could be reprocessed at a minimal cost. Consequently, the cost of raw material per crate was estimated as $1.71.3 Since the machine operators were paid $6.00 per hour (including benefits), the labour cost per crate was computed at $0.14.4
The materials cost to stamp the crates was estimated as $0.01 per side, yielding a total cost of $0.04 per crate. In addition, a stamping machine costing $5000 would have to be acquired. The life of this simple stamping machine was estimated as 10 years, at least. The crates did not require packaging for shipping and the Dairy Council paid for shipment. Michael estimated that the labour costs to load the crates on a truck at the factory door would be $0.02 per crate. As a result of these calculations, Michael believed that the direct variable cost of producing the milk crates would be $1.91 (1.71 + .14 + .04 + 02).
This still left the matter of the overhead associated with producing each milk crate. This issue had been a source of continuing concern to Michael on almost every contract he negotiated. Michael knew that a common ‘rule of thumb’ in his plant was to apply variable overhead to products at a rate of $13 for each machine hour (running time).

Some comparative data on industry economics is summarized in Exhibit 2.
Michael wondered about the accuracy of any of these approaches in general and, in particular, he wondered if anyone was suitable in this situation. Michael looked at the ratio market price to the sum of direct material and direct labour cost for some of his more popular products and found that this ratio varied from two to seven. As a result, he wondered what, if anything, was the implication of the 2.33 factor.
As a guide to understanding the relationship between direct costs (material and labour) and fixed manufacturing overhead Michael developed the data that appear in Exhibit 3. The plant accountant advised Michael that plant fixed manufacturing overhead did not include direct materials, direct labour, variable overhead or plant supervision (about $50 000 per year).
In addition to manufacturing costs, BP was incurring about $220 000 per year in Selling, General and Administrative (S, G & A) expenses.
