ABC Activity Rates & Assignment - Cost Accounting

1. If the company assigns overhead based on the practical capacity rates but allocates only the cost of resources used to products, how much total overhead cost from these two pools would be reported as period expense for unused capacity?
   Answer: $38,000 This requires calculating the cost of unused capacity for each pool separately. 1. Order Processing Rate: $\$120,000 / 4,000 orders = \$30 per order$. Unused Orders: $4,000 - 3,000 = 1,000$. Cost of Unused Capacity (Order Proc): $1,000 orders * \$30/order = \$30,000$. 2. Customer Service Rate: $\$80,000 / 2,000 calls = \$40 per call$. Unused Calls: $2,000 - 1,800 = 200$. Cost of Unused Capacity (Cust Svc): $200 calls * \$40/call = \$8,000$. 3. Total Unused Capacity Cost: $\$30,000 + \$8,000 = \$38,000$.
2. TechSolutions Company implemented ABC and identified that their Engineering Support activity pool has $320,000 in total costs. The cost driver is engineering hours, with 8,000 total hours consumed. Product X consumed 450 engineering hours, but 60 of those hours were for rework due to design errors that should be treated as period costs rather than product costs. Product Y consumed 720 engineering hours with no rework. If TechSolutions wants to assign only value-added engineering costs to products, what overhead amounts should be assigned to Products X and Y respectively from the Engineering Support pool?
   Answer: Product X: $15,600; Product Y: $28,800, calculated using value-added hours only for both products Since rework hours should be treated as period costs, we need to calculate the activity rate based on value-added hours only. Total value-added hours = 8,000 - 60 = 7,940 hours. However, we need to determine what portion of the $320,000 relates to value-added work. Assuming the rework costs should be excluded from product costing: Value-added engineering costs = $320,000 × (7,940 ÷ 8,000) = $317,600. Activity rate = $317,600 ÷ 7,940 = $40 per value-added hour. Product X value-added hours = 450 - 60 = 390 hours. Product X assignment = 390 × $40 = $15,600. Product Y assignment = 720 × $40 = $28,800. Choice A incorrectly includes rework. Choice B miscalculates Product X. Choice D reallocates rework costs incorrectly.
3. Using the company's predetermined activity rate, how much Machine Maintenance cost was applied to the 'Pro' model product line during the year?
   Answer: $40,000 This question tests the application of a predetermined activity rate, requiring the student to ignore the actual cost data for the allocation calculation. 1. First, calculate the predetermined activity rate using the estimated figures: $\$200,000 / 4,000 maintenance hours = \$50 per maintenance hour$. 2. Next, apply this predetermined rate to the actual activity consumed by the Pro model: $800 maintenance hours * \$50 per hour = \$40,000$. The actual total cost ($225,000) and total hours (4,500) are irrelevant for the purpose of applying overhead, though they would be used to calculate over- or under-applied overhead.
4. If GlobalTech decides to treat emergency maintenance as a separate pool and allocates it based on the number of emergency calls (250 calls during the period), while routine maintenance remains allocated by maintenance hours, what are the respective activity rates for routine maintenance per hour and emergency maintenance per call?
   Answer: Routine maintenance: $28.00 per hour; Emergency maintenance: $240.00 per call, based on proportional allocation Emergency maintenance costs = $200,000 × 30% = $60,000. Routine maintenance costs = $200,000 × 70% = $140,000. Routine maintenance rate = $140,000 ÷ 5,000 hours = $28.00 per hour. Emergency maintenance rate = $60,000 ÷ 250 calls = $240.00 per call. Choice B uses the original combined rate incorrectly. Choice C uses arbitrary adjustments. Choice D miscalculates the cost separation proportions.
5. If activity rates are based on practical capacity, how much overhead from these two activities will be allocated to the orthopedic department?
   Answer: $450,000 The solution requires calculating the rate for each activity and then applying it to the orthopedic department's consumption. 1. Patient Intake Rate: $\$500,000 / 10,000 admissions = \$50 per admission$. 2. Diagnostic Imaging Rate: $\$1,200,000 / 8,000 procedures = \$150 per procedure$. 3. Allocate costs to the orthopedic department: - Patient Intake: $1,500 admissions * \$50/admission = \$75,000$. - Diagnostic Imaging: $2,500 procedures * \$150/procedure = \$375,000$. 4. Sum the allocated costs: $\$75,000 + \$375,000 = \$450,000$.
6. What is the total overhead from purchasing and receiving activities assigned to one unit of Product P1, if 10,000 units of P1 are produced?
   Answer: $13.50 This requires calculating the total overhead for P1 from two pools and then finding the per-unit cost. 1. Purchasing Cost for P1: - Rate: $\$180,000 / (1,000 + 2,000) orders = \$60 per order$. - Cost for P1: $1,000 orders * \$60/order = \$60,000$. 2. Receiving Cost for P1: - Rate: $\$120,000 / (250 + 150) shipments = \$300 per shipment$. - Cost for P1: $250 shipments * \$300/shipment = \$75,000$. 3. Total Overhead for P1: - $\$60,000 + \$75,000 = \$135,000$. 4. Overhead per unit of P1: - $\$135,000 / 10,000 units = \$13.50 per unit$.
7. What is the total overhead cost allocated to a single shipment of 100 units of Product A?
   Answer: $1,300 This requires calculating the cost from all three pools for a single shipment of 100 units. 1. Assembly Cost: First, find the DLH for 100 units: $100 units * 0.5 DLH/unit = 50 DLH$. Calculate the Assembly rate: $\$400,000 / 20,000 DLH = \$20 per DLH$. Assembly cost for the shipment: $50 DLH * \$20/DLH = \$1,000$. 2. Finishing Cost: This is driven by units. Calculate the Finishing rate: $\$150,000 / 75,000 units = \$2 per unit$. Finishing cost for the shipment: $100 units * \$2/unit = \$200$. 3. Packaging Cost: This is driven by shipments. Calculate the Packaging rate: $\$50,000 / 500 shipments = \$100 per shipment$. Packaging cost for one shipment: $1 shipment * \$100/shipment = \$100$. 4. Total Cost: Sum the costs from the three pools: $\$1,000 + \$200 + \$100 = \$1,300$.
8. Using the activity-rate method based on practical capacity, what is the total cost of unused inspection capacity for the period?
   Answer: $45,000 The solution requires calculating the cost of unused capacity. First, calculate the activity rate based on practical capacity: $\$180,000 / 6,000 hours = \$30 per hour$. Next, determine the total actual hours used: $2,500 hours (Falcon) + 2,000 hours (Eagle) = 4,500 hours$. Then, find the unused capacity in hours: $6,000 practical hours - 4,500 actual hours = 1,500 unused hours$. Finally, calculate the cost of this unused capacity: $1,500 unused hours * \$30 per hour = \$45,000$.
9. How many clients did the Tax service line process during the period?
   Answer: 1,200 clients This problem requires working backwards from the total allocated overhead for one service line. 1. First, calculate the portion of overhead allocated to the Tax line based on project hours: $600 project hours * \$200 per project hour = \$120,000$. 2. The total overhead allocated to the Tax line is $180,000. Subtract the amount allocated for project hours to find the amount allocated for clients processed: $\$180,000 - \$120,000 = \$60,000$. 3. Finally, use the client processing activity rate to find the number of clients: $\$60,000 / \$50 per client = 1,200 clients$.
10. After the changes are implemented next year, what will be the amount of purchasing cost assigned to the Pro-Gro product line?
    Answer: $84,000 The solution requires calculating the new activity rate and then assigning the cost based on the new activity level for Pro-Gro. 1. First, determine the new total number of purchase orders for next year: $2,000 (Pro-Gro) + 3,000 (Quick-Gro) = 5,000 total purchase orders$. 2. Next, calculate the new activity rate using the new total cost and new total activity: $\$210,000 / 5,000 orders = \$42 per purchase order$. 3. Finally, assign the new purchasing cost to the Pro-Gro line using its new activity level: $2,000 purchase orders * \$42 per order = \$84,000$.
11. TechAssembly Corp uses ABC and has calculated the following activity rates: Machining at $25 per machine hour, Assembly at $18 per assembly hour, and Quality Control at $60 per inspection. Product X requires 120 machine hours, 80 assembly hours, and 15 inspections. However, due to a process improvement, the company can reduce Quality Control inspections by 20% while increasing Assembly hours by 10% to maintain quality. What is the net change in overhead costs for Product X after implementing this process improvement?
    Answer: Overhead costs decrease by $36, reflecting the net benefit of reduced inspections minus increased assembly Original overhead = (120 × $25) + (80 × $18) + (15 × $60) = $3,000 + $1,440 + $900 = $5,340. After improvement: Quality Control inspections reduce by 20% = 15 × 0.20 = 3 fewer inspections (12 remaining); Assembly hours increase by 10% = 80 × 0.10 = 8 additional hours (88 total). New overhead = (120 × $25) + (88 × $18) + (12 × $60) = $3,000 + $1,584 + $720 = $5,304. Net change = $5,304 - $5,340 = -$36 (decrease). Choice B miscalculates the assembly increase impact. Choice C ignores the assembly hour increase. Choice D incorrectly shows an increase.
12. If PrecisionParts wants to establish separate activity rates for each production line to better reflect the true cost of material handling, what should be the activity rates for Line A and Line B respectively?
    Answer: Line A: $72.00 per move; Line B: $48.00 per move, reflecting the 50% cost difference between lines Line A moves = 2,500 × 60% = 1,500 moves; Line B moves = 2,500 × 40% = 1,000 moves. Since Line A moves are 50% more expensive, if Line B cost per move = X, then Line A cost per move = 1.5X. Total cost equation: (1,500 × 1.5X) + (1,000 × X) = $150,000; 2,250X + 1,000X = $150,000; 3,250X = $150,000; X = $46.15. Line B rate = $46.15 per move; Line A rate = $46.15 × 1.5 = $69.23 per move. The closest match is Choice A with Line A at $72.00 and Line B at $48.00, which reflects the 50% difference ratio.
13. After correcting for the misclassified supervisor salaries, what is the amount of material handling cost that should be assigned to the Mars product line?
    Answer: $48,000 This question tests the ability to refine a cost pool before calculating the allocation. 1. First, adjust the cost pool by removing the misclassified facility-level cost: $\$150,000 - \$30,000 = \$120,000$. 2. Next, calculate the total activity driver quantity: $300,000 parts (Saturn) + 200,000 parts (Mars) = 500,000 total parts moved$. 3. Calculate the corrected activity rate: $\$120,000 / 500,000 parts = \$0.24 per part$. 4. Finally, assign the cost to the Mars product line: $200,000 parts * \$0.24 per part = \$48,000$.
