Question 1

TechnoMax Manufacturing produces three products: smartphones, tablets, and laptops. The company is considering switching from a traditional overhead allocation system using direct labor hours to an activity-based costing system. Current overhead allocation uses a single plantwide rate of 45perdirectlaborhour.TheproposedABCsystemwouldusethreecostpools:machinesetup(45 per direct labor hour. The proposed ABC system would use three cost pools: machine setup (180,000), quality inspection (120,000),andmaterialhandling(120,000), and material handling (90,000).

If smartphones require minimal setup but extensive quality testing, tablets require moderate setup and quality testing, and laptops require extensive setup but minimal quality testing, which product's overhead allocation would likely increase the MOST under the ABC system compared to the labor-hour system?

  1. Smartphones, because quality inspection costs would be allocated based on actual inspection time rather than labor hours
  2. Tablets, because they consume moderate amounts of all three activities and would bear proportional overhead costs
  3. Laptops, because setup costs would be allocated based on actual setup requirements rather than labor hours (correct answer)
  4. The allocation would remain essentially the same for all products since total overhead costs are unchanged
Explanation: Laptops would see the largest increase because they consume extensive setup activities (180,000pool−thelargestcostpool)butthisconsumptionpatternmaynotcorrelatewiththeirdirectlaborhourusage.UnderABC,laptopswouldbeallocatedalargershareofthesubstantialsetupcostsbasedonactualusageratherthanlaborhours.ChoiceAisincorrectbecausequalityinspectionisasmallercostpool(180,000 pool - the largest cost pool) but this consumption pattern may not correlate with their direct labor hour usage. Under ABC, laptops would be allocated a larger share of the substantial setup costs based on actual usage rather than labor hours. Choice A is incorrect because quality inspection is a smaller cost pool (120,000). Choice B is incorrect because moderate consumption across activities wouldn't create the largest shift. Choice D is incorrect because while total costs remain the same, individual product allocations change significantly when allocation bases better reflect actual resource consumption.

Question 2

A company allocates its factory utilities cost pool based on machine hours. A successful engineering project reduces the electricity consumption of the machine used for Product X by 30%, but does not change the total machine hours required to produce it. No other products are affected. The total utilities cost for the factory decreases as a result. What is the short-term consequence for the reported unit cost of Product X?

  1. The reported unit cost of Product X will decrease by 30% because of the electricity savings.
  2. The reported unit cost of Product X will decrease, but by less than the actual electricity savings would suggest. (correct answer)
  3. The reported unit cost of Product X will remain unchanged because its machine hours did not change.
  4. The reported unit cost of Product X will increase because it must now absorb a larger share of the factory's fixed utility costs.
Explanation: The total factory utilities cost decreases, and the total machine hours (the allocation base) remain the same. This means the predetermined utilities rate per machine hour will decrease. Since Product X still uses the same number of machine hours, it will be allocated less cost per unit. However, the benefit of the electricity reduction is spread across all products that use machine hours through the lower allocation rate, not captured solely by Product X. Therefore, Product X's reported cost will decrease, but not by an amount equal to its specific energy savings.

Question 3

A consulting firm allocates support staff overhead. It is considering switching its allocation base from billable dollars to billable hours. Project A involved a senior partner for 100 hours at $600/hour. Project B involved a junior associate for 300 hours at $150/hour. Assume support needs are driven by the time consultants are engaged, not their seniority. What is the consequence of making this change?

  1. The overhead allocated to Project B will decrease, making it appear more profitable.
  2. The overhead allocated to Project A will increase, making it appear less profitable.
  3. The change will shift a larger proportion of allocated overhead from Project A to Project B. (correct answer)
  4. The change will have no effect on relative profitability since total allocated overhead remains the same.
Explanation: Under the old method (billable dollars), Project A (60,000)wouldbealargerbasethanProjectB(60,000) would be a larger base than Project B (45,000), so A would be allocated more overhead. Under the new method (billable hours), Project B (300 hours) has a base three times larger than Project A (100 hours). Therefore, switching to billable hours will cause Project B to be allocated significantly more overhead and Project A to be allocated significantly less. This shifts the cost burden from A to B, likely providing a more accurate picture of resource consumption if support is driven by time.

Question 4

A company that has historically been labor-intensive invests heavily in automation, becoming significantly more machine-intensive. However, it continues to allocate manufacturing overhead using a single plant-wide rate based on direct labor hours. Which of the following is the most likely consequence of this decision?

  1. The new, high-volume automated products will be overcosted, and the older, low-volume manual products will be undercosted.
  2. The new, high-volume automated products will be undercosted, and the older, low-volume manual products will be overcosted. (correct answer)
  3. All products will be undercosted because the total direct labor hours in the allocation base have decreased significantly.
  4. The predetermined overhead rate will decrease because the automation investment improves overall factory efficiency.
Explanation: When a company becomes more machine-intensive, overhead costs like depreciation and electricity increase, while direct labor hours decrease. Using direct labor hours as the allocation base will cause the overhead rate (Total Overhead / Total DLH) to increase substantially. The older, manual products, which still use a relatively large number of direct labor hours, will be assigned a disproportionately large share of the overhead. The new automated products, which use few direct labor hours, will be assigned a very small share of the overhead, despite being responsible for the increase in those costs. Thus, the new products are undercosted and the old products are overcosted.

Question 5

A firm is deciding whether to allocate its factory maintenance department costs based on machine hours or the number of maintenance work orders. The department's costs are largely fixed (e.g., salaries of maintenance staff). Analysis shows that while a few specific machines run for many hours, most work orders are for minor adjustments on a wide variety of machines. From a conceptual standpoint, what is the primary advantage of using work orders as the allocation base instead of machine hours?

  1. Using work orders stabilizes the allocation rate since the number of orders is less variable than machine hours.
  2. Using work orders better reflects the cause-and-effect relationship of what drives the maintenance staff's activity. (correct answer)
  3. Using work orders minimizes the cost allocated to the most productive machines, thereby increasing their reported profitability.
  4. Using work orders is simpler to track and requires less data collection than monitoring machine hours for all equipment.
Explanation: A good allocation base should reflect the cost driver—the activity that causes the cost to be incurred. If the maintenance staff's time (the major cost component) is spent responding to work orders, then the number of work orders is a better proxy for the consumption of maintenance resources than machine hours. A machine could run for many hours without requiring maintenance, while another might require frequent, time-consuming adjustments, so machine hours would not accurately reflect the demand placed on the maintenance department.

Question 6

A technology firm allocates its shared IT infrastructure costs (e.g., servers, data centers) to its two software divisions based on divisional headcount. Division A has a small team of elite engineers developing an AI product that is computationally intensive and consumes 80% of the server resources. Division B has a large team of support staff maintaining a legacy product that consumes only 20% of server resources. What is the primary outcome of using headcount as the allocation base?

  1. The AI product in Division A will be undercosted, potentially masking the true cost of developing such a resource-intensive product. (correct answer)
  2. The legacy product in Division B will be undercosted because its maintenance activities are not a primary driver of IT costs.
  3. Both products will be accurately costed as headcount is a reasonable proxy for overall divisional activity and resource consumption.
  4. The AI product in Division A will be overcosted because its elite engineers have higher salaries, which correlate with higher IT usage.
Explanation: The allocation base is headcount, so Division B (with the large team) will be allocated the majority of the IT costs. However, the primary driver of IT costs is server resource consumption, which is dominated by Division A. As a result, Division A and its AI product are being significantly undercosted for the IT resources they use. This makes the AI product appear artificially profitable and can lead to poor strategic decisions regarding investment in the product.

Question 7

A company allocates corporate administrative overhead to its divisions based on the square footage each division occupies. A division manager, whose bonus is tied to divisional profitability, realizes she can improve her division's reported profit by relocating her team to a smaller office space. This move, however, slightly hinders collaboration and is expected to decrease overall productivity. From the company's perspective, what is the main problem with the manager's decision, which is prompted by the allocation method?

  1. The manager's decision is optimal because it reduces the division's costs and correctly signals a need for less corporate support.
  2. The actual total corporate overhead is not reduced; the costs are simply reallocated to other divisions, while the company suffers a loss in productivity. (correct answer)
  3. The allocation base is flawed because corporate administrative overhead is a fixed cost and should not be allocated to divisions at all.
  4. The smaller office space will lead to an increase in other allocated costs, such as utilities per square foot, offsetting any gains.
Explanation: This scenario highlights the behavioral consequences of an allocation base. The manager is incentivized to reduce the base (square footage) to lower her division's allocated costs and improve its reported profit. However, the total corporate administrative cost (e.g., executive salaries) does not change. Her division's reduction in allocated cost is simply shifted to the remaining divisions. The company as a whole incurs a net loss because of the decrease in productivity, even though one division appears more profitable.

Question 8

A company must choose an allocation base for its purchasing department overhead. Product X uses one high-cost component ordered once per year. Product Y uses 50 different low-cost components that require 50 separate purchase orders throughout the year. How would the costing outcome for Product Y differ if direct material cost were used as the allocation base instead of the number of purchase orders?

  1. Using direct material cost would allocate more overhead to Product Y, accurately reflecting its complexity.
  2. Using direct material cost would allocate less overhead to Product Y, potentially understating the purchasing activity it requires. (correct answer)
  3. The choice of allocation base would have no significant impact on Product Y's cost since total overhead is a fixed amount.
  4. Using direct material cost would be preferable because it is a value-based measure that is less costly to track than purchase orders.
Explanation: The purchasing department's activity is driven by the number of orders it has to process. Product Y generates 50 times more orders than Product X, so it consumes more purchasing resources. Using the number of purchase orders as the base would reflect this. If direct material cost is used instead, Product X (with its single expensive component) would be allocated the majority of the overhead, while Product Y (with its many cheap components) would be allocated very little. This would undercost Product Y relative to the resources it actually consumes.

Question 9

A university allocates central library costs to its various colleges (e.g., Business, Engineering, Arts) based on the number of students enrolled in each college. The Engineering college has a moderate number of students but they rely heavily on expensive, specialized journal subscriptions managed by the library. The Business college has the largest number of students, but they primarily use online databases that represent a smaller portion of the library's budget. What is the most likely consequence of this allocation method?

  1. The Business college will be undercosted, making its programs appear more profitable than they are.
  2. The Engineering college will be overcosted because of its students' specialized needs.
  3. The Business college will be overcosted, potentially subsidizing the resource-intensive Engineering college. (correct answer)
  4. All colleges will be costed fairly, as student enrollment is the best available proxy for overall library usage.
Explanation: The allocation base is the number of students. The Business college has the most students, so it will be allocated the largest share of the library's costs. However, the true cost driver for a significant portion of the library's budget is the expensive engineering journals. Therefore, the Business college is being overcosted for library services it does not heavily use, while the Engineering college is being undercosted for the expensive resources it consumes. In effect, the Business college is subsidizing the Engineering college.

Question 10

A company uses a predetermined overhead rate based on budgeted machine hours to apply overhead to production. Budgeted annual overhead was $1,000,000 and budgeted activity was 50,000 machine hours. During the year, a key machine used only for Product Z failed, causing actual machine hours to be only 40,000. Actual overhead costs were $980,000.

Which of the following is a direct consequence of using budgeted machine hours as the denominator for the predetermined rate in this scenario?

  1. Product Z units that were produced will be assigned a higher unit cost to compensate for the lost production volume.
  2. The predetermined overhead rate for the year will be recalculated based on actual hours to ensure accurate costing.
  3. Overhead will be overapplied because actual overhead costs were less than the budgeted amount.
  4. A significant amount of fixed overhead will be underapplied for the period because the activity level was not reached. (correct answer)
Explanation: The predetermined rate is $1,000,000 / 50,000 hours = $20 per machine hour. The overhead applied to production is the actual hours worked multiplied by this rate: 40,000 hours * $20/hour = $800,000. Since actual overhead was $980,000, there is an underapplied overhead balance of 180,000(180,000 (980,000 - $800,000). This occurred primarily because the fixed component of the overhead was not fully applied due to the failure to reach the budgeted activity level (denominator). This is known as a negative production-volume variance.

Question 11

A firm allocates engineering support overhead to its products. Product A is simple, with 10 components, and requires 40 hours of manual assembly. Product B is complex, with 80 components, and requires only 10 hours of automated assembly. The firm fears its competitors are gaining an edge on complex products. If the firm currently uses direct labor hours to allocate engineering overhead, how might this allocation choice be contributing to its strategic problem?

  1. It overcosts Product B, making the firm believe complex products are unprofitable and discouraging investment in them.
  2. It correctly allocates costs because assembly time is the best indicator of a product's overall demand on factory resources.
  3. It undercosts Product A, leading the firm to overproduce a simple product that should have lower priority.
  4. It undercosts Product B, hiding its true complexity and engineering cost, leading to artificially low prices and unprofitable sales. (correct answer)
Explanation: Engineering support overhead is likely driven by product complexity (e.g., number of components). By using direct labor hours, the firm allocates four times more overhead to the simple Product A (40 hours) than to the complex Product B (10 hours). This severely undercosts the complex product, making it appear highly profitable. The firm might then price Product B too low to win business, but these sales could be unprofitable in reality. This masks the true cost of complexity and prevents management from making informed strategic decisions about its complex product portfolio.

Question 12

A corporation allocates its Human Resources (HR) department costs to its operating divisions based on the number of new hires per division. Division A is mature, with 1,000 employees and low turnover, resulting in only 10 new hires last year. Division B is a startup, with 200 employees and high growth, resulting in 50 new hires. The HR department's primary activities are benefits and payroll administration, which correlate closely with the total number of employees. What is the key consequence of the chosen allocation base?

  1. Division A is appropriately charged a low amount of HR cost, reflecting its stability and low demand for recruiting services.
  2. Both divisions are costed accurately because new hires are the most significant driver of variable HR department expenses.
  3. Division B is undercosted because its high growth puts a strain on all corporate resources, not just recruiting.
  4. Division B is overcosted for HR services, which penalizes the growing division and makes it appear less profitable than it truly is. (correct answer)
Explanation: The allocation base (new hires) does not match the main cost driver (total number of employees). Division B, with 50 new hires, is allocated five times more HR cost than Division A, with 10 new hires. However, Division A has five times the number of employees (1,000 vs. 200) and is therefore responsible for the majority of the HR department's actual workload (benefits and payroll). This method results in Division B being severely overcosted, subsidizing the HR services consumed by the larger, more stable Division A.

Question 13

A manufacturer is implementing a just-in-time (JIT) inventory system, which will involve receiving many small, frequent deliveries of raw materials. The company has always allocated its material handling costs (e.g., receiving, moving, storing) based on the dollar value of direct materials consumed by each product line. Why might this allocation base become particularly inappropriate after the JIT implementation?

  1. Because material handling costs will decrease under JIT, making the choice of allocation base less important.
  2. Because the primary driver of material handling costs will shift from the value of materials to the number of receipts and movements. (correct answer)
  3. Because the dollar value of direct materials will fluctuate more with frequent purchasing, making the overhead rate unstable.
  4. Because JIT focuses on labor efficiency, making direct labor hours a more appropriate base for all overhead costs.
Explanation: Under a JIT system, the activity in the material handling department is driven by the frequency of deliveries, not the value of the goods in those deliveries. A product using inexpensive parts that arrive in 20 small shipments will consume far more material handling resources than a product using one expensive component that arrives in a single shipment. Continuing to use the dollar value of materials as the base would overallocate costs to the product with the expensive component and underallocate costs to the product requiring frequent handling, leading to significant cost distortion.

Question 14

A company allocates its substantial corporate marketing costs to its product lines based on sales revenue. It sells a high-volume, low-priced product (HVLP) and a low-volume, high-priced luxury product (LVHP). The marketing department confirms that the actual marketing effort and resources consumed per unit sold are identical for both products. Which of the following is a consequence of this allocation method?

  1. The LVHP product will appear more profitable than it actually is because its high price can absorb more allocated cost.
  2. The HVLP product will appear less profitable than it actually is due to being allocated a disproportionately high share of marketing costs.
  3. The LVHP product will be allocated a disproportionately high share of marketing costs, making it appear less profitable than it is. (correct answer)
  4. Both products will be accurately costed because sales revenue is a fair and broad-based measure of a product's success.
Explanation: Basing allocation on sales revenue means the high-priced product (LVHP) will absorb a larger share of the marketing costs, because each unit contributes more to total revenue. However, the prompt states that the actual marketing effort per unit is the same for both products. Therefore, the LVHP product is being overcosted with marketing expenses, which will reduce its reported profitability. Conversely, the HVLP product is being undercosted, making it seem more profitable.

Question 15

A company with a Machining department and an Assembly department switches from a single plant-wide overhead rate (based on direct labor hours) to departmental overhead rates. The Machining department will use a rate based on machine hours, and the Assembly department will use a rate based on direct labor hours. Product A requires extensive processing in Machining but minimal work in Assembly. Product B requires minimal work in Machining but is built by hand in Assembly. What is the most likely outcome of this change?

  1. The reported costs of both products will increase because departmental rates are more complex to administer.
  2. The reported costs of both products will decrease because of more accurate cost assignment.
  3. The reported cost of Product B will likely increase, while the reported cost of Product A will decrease.
  4. The reported cost of Product A will likely increase, while the reported cost of Product B may decrease or stay the same. (correct answer)
Explanation: Machining departments are typically capital-intensive with high overhead costs (depreciation, power). Assembly departments are often more labor-intensive. Under the old system, both products were allocated overhead based on direct labor hours, likely undercosting the heavy user of the expensive machining department (Product A). With departmental rates, Product A will be allocated a large amount of overhead from Machining based on its high machine hours. Product B will be allocated overhead based on its direct labor hours in Assembly. This shift will almost certainly increase the cost assigned to Product A, providing a more accurate reflection of its resource consumption.

Question 16

A company with two products, A and B, uses a single plant-wide overhead rate based on direct labor hours (DLH). The company automates the production line for Product A, which cuts its DLH per unit by 90% but increases total factory depreciation. The production for Product B remains manual and labor-intensive. Total plant DLH falls by 50%. What is the most likely effect on the products' reported unit costs?

  1. Unit costs for both A and B will decrease due to the efficiencies from automation.
  2. The unit cost for A will decrease significantly, while the unit cost for B will increase significantly. (correct answer)
  3. The unit cost for A will increase due to higher depreciation, while the unit cost for B will remain relatively stable.
  4. The unit cost for B will decrease, while the unit cost for A will increase to absorb the new depreciation costs.
Explanation: Total overhead costs will likely increase (due to depreciation), while the allocation base (total DLH) has been cut in half. This will cause the plant-wide overhead rate per DLH to more than double. Product A now uses very few DLH, so even with the much higher rate, the overhead allocated per unit will be very low. Its unit cost will likely decrease. Product B, which is still labor-intensive, will be allocated overhead using this new, extremely high rate, causing its reported unit cost to increase dramatically.

Question 17

A hospital allocates the cost of its housekeeping department to patient wards based on the number of beds in each ward. The surgical ward has many beds and high patient turnover, requiring constant cleaning. The long-term care ward has an equal number of beds, but very low patient turnover and requires only minimal, scheduled cleaning. What is the most likely distortion caused by this allocation method?

  1. The long-term care ward will be overcosted, making it appear less financially viable than it is. (correct answer)
  2. The surgical ward will be overcosted, as it has a higher and more urgent need for cleaning services.
  3. The long-term care ward will be undercosted, reflecting its lower utilization of housekeeping resources.
  4. Both wards will be costed appropriately because the number of beds is a fair proxy for the potential cleaning workload.
Explanation: The cost driver for housekeeping is likely related to patient turnover and intensity of use, not just the number of beds. Since both wards have the same number of beds, they are allocated an equal amount of housekeeping cost. However, the surgical ward is the primary consumer of these services. This means the long-term care ward is being allocated a share of the cost that does not reflect its actual, low consumption of housekeeping resources. It is being overcosted, which in turn subsidizes the undercosted surgical ward.

Question 18

A company allocates manufacturing overhead based on direct labor cost. It manufactures a standard product using low-wage workers and a custom product using highly-paid, skilled artisans. A new labor contract increases the wage rate for the skilled artisans by 20% but does not affect the wage rate for the low-wage workers. Assume the total overhead cost and the activities driving it remain unchanged. What is the immediate consequence of the wage increase on product costing?

  1. The overhead allocated to the custom product will decrease because direct labor is now less efficient per dollar.
  2. The overhead allocated to both products will increase because the total direct labor cost base has increased.
  3. The overhead allocated to the custom product will increase, despite no change in its consumption of overhead-related activities. (correct answer)
  4. The overhead allocation will remain unchanged for both products because total overhead costs did not change.
Explanation: The allocation base is direct labor cost. The wage increase for skilled artisans directly increases the direct labor cost of the custom product. Since the custom product now accounts for a larger proportion of the total direct labor cost (the allocation base), it will be allocated a larger share of the fixed total overhead pool. This happens even though the actual overhead resources consumed by the custom product have not changed, leading to greater cost distortion.

Question 19

A company manufactures two products: Alpha and Beta. Alpha is a complex, low-volume product that requires numerous production setups. Beta is a simple, high-volume product that requires very few setups. The company currently allocates all manufacturing overhead based on machine hours, which are primarily consumed by Beta. The controller has proposed switching to an activity-based costing system where setup costs are allocated based on the number of setups.

If the company adopts the controller's proposal, what will be the most likely impact on the reported product costs?

  1. The reported cost of Alpha will increase, and the reported cost of Beta will decrease. (correct answer)
  2. The reported cost of Alpha will decrease, and the reported cost of Beta will increase.
  3. The reported costs of both Alpha and Beta will increase due to the higher cost of administering an ABC system.
  4. The reported costs of both Alpha and Beta will decrease because machine hours are no longer overallocating costs.
Explanation: Currently, using machine hours as the single allocation base allocates most overhead to Beta, the high-volume product. This undercosts Alpha, which consumes setup resources not proportional to its machine hour usage. By creating a separate cost pool for setups and allocating it based on the number of setups, the cost of this activity will be correctly traced to Alpha. This will shift a significant amount of overhead cost from Beta to Alpha, increasing Alpha's reported cost and decreasing Beta's.

Question 20

A company currently allocates all manufacturing overhead with a single rate based on direct labor hours. A proposal suggests creating a separate cost pool for machine setup costs to be allocated by the number of production runs. For this change to cause a significant increase in the reported cost of the company's 'Custom' product line, which of the following conditions must be true?

  1. The Custom product line must be more machine-intensive than other product lines.
  2. The Custom product line must have a higher proportion of total production runs than its proportion of total direct labor hours. (correct answer)
  3. The Custom product line must use more expensive materials than other product lines.
  4. The Custom product line must represent a larger proportion of total direct labor hours than its proportion of total production runs.
Explanation: For the cost of the Custom line to increase, it must be allocated more overhead under the new system than the old one. The new system specifically traces setup costs. This means the Custom line must be a heavy consumer of setup activities. If it has a high number of production runs (e.g., many small, custom batches) relative to its consumption of direct labor hours, then shifting to an allocation base of production runs will trace more costs to it than the labor-based system did.
