A) -$79,100 B) -$21,700 C) -$4,500 D) $52,900 Solution: Incremental revenue from reworking ($54,400 − $1,500). $52,900 Less incremental revenue from selling as scrap................ 57,400 Net loss from reworking.................................................... ($ 4,500) 27. Milford Corporation has in stock 16,100 kilograms of material R that it bought five years ago for $5.75 per kilogram. This raw material was purchased to use in a product line that has been discontinued. Material R can be sold as is for scrap for $3.91 per kilogram. An alternative would be to use material R in one of the company's current products, S88Y, which currently requires 2 kilograms of a raw material that is available for $7.60 per kilogram. Material R can be modified at a cost of $0.77 per kilogram so that it can be used as a substitute for this material in the production of product S88Y. However, after modification, 4 kilograms of material R is required for every unit of product S88Y that is produced. Milford Corporation has now received a

Chapter 13 Relevant Costs for Decision Making request from a company that could use material R in its production process. Assuming that Milford Corporation could use all of its stock of material R to make product S88Y or the company could sell all of its stock of the material at the current scrap price of $3.91 per kilogram, what is the minimum acceptable selling price of material R to the company that could use material R in its own production process? A) $0.88 B) $3.03 C) $4.57 D) $3.91 Solution: Product S88Y: Current cost (2 kg @ $7.60): $15.20 If material R were used, 4 kilograms would be needed. It currently costs $15.20 for Product S88Y; to maintain this same cost, material R would need to cost $3.03 per kilogram [($15.20 ÷ 4 kg) − $0.77]. The company should sell material R for $3.91 per kilogram. 28. Otool Inc. is considering using stocks of an old raw material in a special project. The special project would require all 240 kilograms of the raw material that are in stock and that originally cost the company $2,112 in total. If the company were to buy new supplies of this raw material on the open market, it would cost $9.25 per kilogram. However, the company has no other use for this raw material and would sell it at the discounted price of $8.35 per kilogram if it were not used in the special project. The sale of the raw material would involve delivery to the purchaser at a total cost of $71.00 for all 240 kilograms. What is the relevant cost of the 240 kilograms of the raw material when deciding whether to proceed with the special project? A) $1,933 B) $2,004 C) $2,220 D) $2,112 Solution: Opportunity cost of sales foregone if special project is undertaken ($8.35 × 240)............................................... $2,004 Less: delivery cost.............................................................. 71 Relevant cost of 240 kilograms of raw material................ $1,933 29. Hamby Corporation is preparing a bid for a special order that would require 780 liters of material W34C. The company already has 640 liters of this raw material in stock that originally cost $8.30 per liter. Material W34C is used in the company's main product and is replenished on a periodic basis. The resale value of the existing stock of the material is $7.60 per liter. New stocks of the material can be readily purchased for $8.35 per liter. What is the relevant cost of the 780 liters of the raw material when deciding how much to bid on the special order?

Chapter 13 Relevant Costs for Decision Making 47. Sardi Inc. is considering whether to continue to make a component or to buy it from an outside supplier. The company uses 17,000 of the components each year. The unit product cost of the component according to the company's cost accounting system is given as follows: Direct materials.......................................... Direct labor................................................ Variable manufacturing overhead.............. Fixed manufacturing overhead.................. Unit product cost........................................

$ 8.20 8.30 1.20 4.30 $22.00

Assume that direct labor is a variable cost. Of the fixed manufacturing overhead, 70% is avoidable if the component were bought from the outside supplier. In addition, making the component uses 2 minutes on the machine that is the company's current constraint. If the component were bought, this machine time would be freed up for use on another product that requires 4 minutes on the constraining machine and that has a contribution margin of $7.00 per unit. When deciding whether to make or buy the component, what cost of making the component should be compared to the price of buying the component?

The facilities now being used to produce Part MR24 have a fixed monthly cost of $150,000 and a capacity to produce 35,000 units per month. If Elly were to buy part MR24 from an outside supplier, the facilities would be idle, but its fixed costs would continue at 40% of their present amount. The variable production costs of Part MR24 are $11 per unit. 86.

Chapter 13 Relevant Costs for Decision Making Solution: A company will be indifferent between purchasing and making a part when the outside purchase price is equal to the total relevant cost per unit of making the part. The total relevant cost per unit of making the part is composed of the variable production cost per unit ($11) plus the fixed cost per unit. Since the total cost must be equal to $15, then the fixed cost per unit must be $4 ($15 − $11). The fixed cost per unit is calculated as: Fixed cost per unit = Total relevant fixed costs ÷ Units to be produced Substituting: $4 = $90,000 ÷ Units to be produced Units to be produced = 22,500 Use the following to answer questions 88-90: Ahron Company makes 80,000 units per year of a part it uses in the products it manufactures. The unit product cost of this part is computed as follows: Direct materials.......................................... Direct labor................................................ Variable manufacturing overhead.............. Fixed manufacturing overhead.................. Unit product cost........................................

$14.90 17.50 1.90 21.10 $55.40

An outside supplier has offered to sell the company all of these parts it needs for $46.60 a unit. If the company accepts this offer, the facilities now being used to make the part could be used to make more units of a product that is in high demand. The additional contribution margin on this other product would be $560,000 per year. If the part were purchased from the outside supplier, all of the direct labor cost of the part would be avoided. However, $13.60 of the fixed manufacturing overhead cost being applied to the part would continue even if the part were purchased from the outside supplier. This fixed manufacturing overhead cost would be applied to the company's remaining products.

Chapter 13 Relevant Costs for Decision Making 131. Companies often allocate common fixed costs among segments. For example, common fixed corporate costs are often allocated to divisions and appear as part of the divisional performance reports. Required: What dangers are there in allocating common fixed costs to segments when involved in a decision to possibly drop a segment such as a product or a division? Ans: A segment such as a product or a division may show a net loss only because of the allocated common fixed cost. However, if the segment is dropped, the common fixed expense will continue. A segment should be dropped only if its contribution margin does not cover its own avoidable fixed costs. And even in cases where a segment does not cover its own costs, it may be beneficial to retain the segment if it has positive effects on other segments. For example, a “losing” product may be important in luring customers into a store where they will buy other products.

Variable manufacturing overhead........ Fixed manufacturing overhead............ Unit product cost..................................

$13.80 18.10 4.30 24.60 $60.80

An outside supplier has offered to sell the company all of these parts it needs for $51.80 a unit. If the company accepts this offer, the facilities now being used to make the part could be used to make more units of a product that is in high demand. The additional contribution margin on this other product would be $268,000 per year. If the part were purchased from the outside supplier, all of the direct labor cost of the part would be avoided. However, $17.00 of the fixed manufacturing overhead cost being applied to the part would continue even if the part were purchased from the outside supplier. This fixed manufacturing overhead cost would be applied to the company's remaining products. Required: a. How much of the unit product cost of $60.80 is relevant in the decision of whether to make or buy the part? b.

An outside supplier has offered to supply component P0 for $78 each. The outside supplier is known for quality and reliability. Assume that direct labor is a variable cost, variable manufacturing overhead is really driven by direct labor-hours, and total fixed manufacturing overhead would not be affected by this decision. Gottshall chronically has idle capacity. Required: Is the offer from the outside supplier financially attractive? Why?

Garrison/Noreen/Brewer, Managerial Accounting, Twelfth Edition

13-115

Chapter 13 Relevant Costs for Decision Making Ans: Direct materials, direct labor, and variable manufacturing overhead are relevant in this decision. Fixed manufacturing overhead is not relevant since it would not be affected by the decision. The variable portion of the manufacturing overhead rate is computed as follows: Variable portion of the predetermined overhead rate = Variable manufacturing overhead ÷ Direct labor-hours = $225,000 ÷ 45,000 DLHs = $5.00 per DLH The direct-labor hours per unit for the special order can be determined as follows: Direct labor-hours = Manufacturing overhead applied ÷ Predetermined overhead rate = $32.30 ÷ $19.00 per DLH = 1.70 DLHs Consequently, the variable manufacturing overhead for the special order would be: Variable manufacturing overhead = Variable portion of the predetermined overhead rate × Direct labor-hours = $5.00 per DLH × 1.70 DLHs = $8.50 Putting this all together: Direct materials.......................................... Direct labor................................................ Variable manufacturing overhead.............. Total variable cost......................................

$21.00 40.80 8.50 $70.30

Since the outside supplier has offered to sell the component for $78.00 each, but it only costs the company $70.30 to make the component internally, this is not a financially attractive offer.

The costs associated with production and sale of the company's product are given below: Manufacturing costs: Variable................................................... Fixed (annual cost).................................. Selling and administrative costs: Variable (sales commissions).................. Fixed (annual cost)..................................

$12 per unit $90,000 $3 per unit $60,000

The company presently is selling 12,000 units annually at a selling price of $28 each. A special order has been received from a distributor who wants to purchase 3,000 units at a special price of $20 each. Regular sales would not be affected by this order and the order could be filled without any impact on total fixed costs. Sales commissions on the special order would be reduced by one-third. Required: Determine whether the company should accept the special order. Ans: Incremental revenues (3,000 units @ $20)............ Less incremental costs: Variable manufacturing (3,000 units @ $12)...... Variable selling (3,000 units @ $2).................... Net advantage of accepting the order.....................

Chapter 13 Relevant Costs for Decision Making 143. Mcniff Corporation makes a range of products. The company's predetermined overhead rate is $28 per direct labor-hour, which was calculated using the following budgeted data: Variable manufacturing overhead.............. $180,000 Fixed manufacturing overhead.................. $380,000 Direct labor-hours...................................... 20,000 Management is considering a special order for 200 units of product O96S at $122 each. The normal selling price of product O96S is $149 and the unit product cost is determined as follows: Direct materials.......................................... Direct labor................................................ Manufacturing overhead applied............... Unit product cost........................................

$ 67.00 32.00 44.80 $143.80

If the special order were accepted, normal sales of this and other products would not be affected. The company has ample excess capacity to produce the additional units. Assume that direct labor is a variable cost, variable manufacturing overhead is really driven by direct labor-hours, and total fixed manufacturing overhead would not be affected by the special order. Required: If the special order were accepted, what would be the impact on the company's overall profit? Ans: Direct materials, direct labor, and variable manufacturing overhead are relevant in this decision. Fixed manufacturing overhead is not relevant since it would not be affected by the decision. The variable portion of the manufacturing overhead rate is computed as follows: Variable portion of the predetermined overhead rate = Variable manufacturing overhead ÷ Direct labor-hours = $180,000 ÷ 20,000 direct labor-hours = $9.00 per direct labor-hour

The company has just received a special one-time order for 500 medals at $89 each. For this particular order, no variable selling and administrative costs would be incurred. This order would also have no effect on fixed costs. Required: Should the company accept this special order? Why? Ans: Only the direct materials and direct labor costs are relevant in this decision. To make the decision, we must compute the average direct materials and direct labor cost per unit. Direct materials...............................................................
