- 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?
Answer: The unit cost for A will decrease significantly, while the unit cost for B will increase significantly.
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.
- Which of the following is a direct consequence of using budgeted machine hours as the denominator for the predetermined rate in this scenario?
Answer: A significant amount of fixed overhead will be underapplied for the period because the activity level was not reached.
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 ($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.
- 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?
Answer: Laptops, because setup costs would be allocated based on actual setup requirements rather than labor hours
Laptops would see the largest increase because they consume extensive setup activities ($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.
- 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?
Answer: Division B is overcosted for HR services, which penalizes the growing division and makes it appear less profitable than it truly is.
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.
- 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?
Answer: The Custom product line must have a higher proportion of total production runs than its proportion of total direct labor hours.
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.
- 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?
Answer: The Business college will be overcosted, potentially subsidizing the resource-intensive Engineering college.
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.
- A company discovers that its overhead allocation base (square footage of production space) has a correlation coefficient of 0.15 with actual overhead cost drivers. The allocation base is easy to measure and remains stable over time. From a cost-benefit perspective, what is the STRONGEST argument for maintaining this allocation method?
Answer: Square footage provides an objective, verifiable basis that eliminates disputes over overhead allocation among departments
The strongest argument is that square footage provides an objective, verifiable, and dispute-free allocation basis. While accuracy is compromised (0.15 correlation is very weak), the administrative benefits of simplicity, objectivity, and acceptance by all parties may outweigh the costs of developing a more complex but accurate system. Choice A is incorrect because a 0.15 correlation indicates substantial distortion, not minimal distortion. Choice B incorrectly assumes overhead is a small portion of costs, which isn't stated. Choice D, while technically correct about correlation limitations, doesn't provide a strong cost-benefit argument for maintaining the current system compared to the administrative advantages in Choice C.
- 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?
Answer: The reported cost of Product A will likely increase, while the reported cost of Product B may decrease or stay the same.
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.
- If the company switches from machine hours to direct labor hours as the allocation base, what will happen to the relative profitability ranking of the two products?
Answer: Product X will become relatively more profitable because it uses fewer direct labor hours per unit than Product Y
Product X will become relatively more profitable because it will be allocated less overhead under the direct labor hour system (2 labor hours vs. 8 machine hours per unit). Since most overhead ($300,000 of $400,000) is machine-related, Product X should bear more overhead costs than Product Y, but under labor hours, it will bear less. The overhead rate under machine hours would be $40/machine hour, giving Product X $320/unit and Product Y $80/unit. Under labor hours, the rate would be $50/labor hour, giving Product X $100/unit and Product Y $300/unit. Choice B is incorrect because Product Y will become relatively less profitable. Choice C is incorrect because allocation base changes affect relative cost assignments. Choice D incorrectly states the direction of the profitability change.
- 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?
Answer: The new, high-volume automated products will be undercosted, and the older, low-volume manual products will be overcosted.
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.
- 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?
Answer: Because the primary driver of material handling costs will shift from the value of materials to the number of receipts and movements.
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.
- A manufacturing company allocates overhead using machine hours for Department A and direct labor hours for Department B. Department A is highly automated while Department B is labor-intensive. If the company switches to a plantwide allocation rate based on total direct labor hours, which outcome is MOST likely?
Answer: Department B products will be over-costed because they will absorb Department A's machine-related overhead costs
Department B products will be over-costed because they use significant direct labor hours and will therefore absorb a disproportionate share of Department A's machine-related overhead costs under the plantwide labor-hour system. Since Department A is highly automated with low labor hours but high machine-related overhead, this overhead will be allocated to Department B's labor-intensive products. Choice A is incorrect because Department A products will actually be under-costed, not over-costed. Choice C is incorrect because using a single allocation base that doesn't reflect actual cost drivers decreases accuracy. Choice D is incorrect because Department A products will receive less overhead allocation due to their minimal labor hours.
- 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?
Answer: The change will shift a larger proportion of allocated overhead from Project A to Project B.
Under the old method (billable dollars), Project A ($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.
- If the company adopts the controller's proposal, what will be the most likely impact on the reported product costs?
Answer: The reported cost of Alpha will increase, and the reported cost of Beta will decrease.
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.
- 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?
Answer: The AI product in Division A will be undercosted, potentially masking the true cost of developing such a resource-intensive product.
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.
- 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?
Answer: It undercosts Product B, hiding its true complexity and engineering cost, leading to artificially low prices and unprofitable sales.
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.
- 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?
Answer: The reported unit cost of Product X will decrease, but by less than the actual electricity savings would suggest.
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.
- 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?
Answer: The overhead allocated to the custom product will increase, despite no change in its consumption of overhead-related activities.
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.
- Based on the production characteristics described, which statement BEST explains the likely impact of switching to ABC on product costing decisions?
Answer: Aerospace parts will be allocated higher overhead costs overall, providing better information for pricing and product mix decisions
Aerospace parts will be allocated higher overhead costs under ABC because they consume disproportionate amounts of setup/changeover ($400,000), quality control ($500,000), and engineering support ($300,000) activities due to small batches, customization, and quality requirements. These costs represent $1,200,000 of the $2,000,000 total overhead. Under labor hours, this consumption pattern was hidden, leading to under-costing of aerospace parts. Choice A is incorrect because automotive parts, with their standardized high-volume production, consume fewer of these specialized activities. Choice C is incorrect because the impact extends well beyond machine operations. Choice D is incorrect because using the same facility doesn't mean consuming overhead activities proportionally.
- Assuming Digital Printing typically produces small batches with frequent setups while Traditional Printing produces large batches with infrequent setups, what would be the MOST significant strategic consequence of switching allocation methods?
Answer: Digital Printing will appear less profitable, potentially leading to incorrect decisions about product mix and pricing strategies
Digital Printing will appear less profitable under the new system because it will absorb a larger share of the substantial setup costs ($600,000) due to its frequent production runs, whereas under volume-based allocation, these costs were spread across all units regardless of setup intensity. This could lead to strategic errors such as discontinuing profitable Digital Printing services or pricing them too high. Choice B is incorrect because Traditional Printing will actually benefit from the change. Choice C is incorrect because while allocation accuracy improves, Digital Printing's apparent profitability decreases. Choice D understates the significant impact on profitability analysis, especially for Digital Printing.
