Product vs. Period Costs - Cost Accounting

1. When are the wages of a factory maintenance worker ultimately recognized as an expense on the income statement?
   Answer: In the period the products the worker helped produce are sold. The wages of a factory maintenance worker are a form of indirect labor, which is a component of manufacturing overhead. Manufacturing overhead is a product cost. Product costs are capitalized into inventory when incurred. They are only recognized as an expense (Cost of Goods Sold) on the income statement when the inventory to which they are attached is sold. The timing of the work or payment is irrelevant to the timing of the expense recognition.
2. For external financial reporting purposes under U.S. GAAP, what total amount of these value chain costs is considered inventoriable product cost?
   Answer: $200,000 For external financial reporting, only costs incurred during the manufacturing/production phase are treated as inventoriable product costs. Upstream costs (like research and product design) and downstream costs (like marketing and distribution) are treated as period costs and expensed as incurred. Therefore, only the $200,000 of manufacturing costs are product costs.
3. A manufacturing firm paid $90,000 for its annual factory insurance premium. The controller incorrectly classified the entire amount as an administrative expense. During the year, the firm produced 10,000 units and sold 8,000 units. What is the net effect of this classification error on the company's annual net income before taxes?
   Answer: Net income is understated by $18,000. Factory insurance is a product cost (manufacturing overhead). The $90,000 should have been added to inventory. Since 8,000 of 10,000 units (80%) were sold, the correct expense in Cost of Goods Sold would be 80% $90,000 = $72,000. The remaining 20% $90,000 = $18,000 should be in ending inventory. By expensing the full $90,000 as a period cost, the company's total expenses are overstated by $90,000 - $72,000 = $18,000. This causes net income to be understated by $18,000.
4. How should TechCorp classify the customer service department costs for October?
   Answer: $20,000 as product cost, $30,000 as period cost for appropriate matching Only warranty costs for products sold in the current period ($50,000 × 40% = $20,000) should be treated as product costs and matched against current sales. Warranty costs for previously sold products ($17,500) and fee-based services ($12,500) are period costs totaling $30,000. The key distinction is that warranty obligations are part of the product's cost and should be matched with the revenue from the sale, but only for the current period's sales.
5. A manufacturing company's assembly line workers are paid $20 per hour for regular time and time-and-a-half for overtime. An individual worker's overtime premium, incurred due to a general high volume of orders rather than a specific rush job, is best classified as:
   Answer: Manufacturing overhead, because it is an indirect cost of production. The overtime premium for direct labor that is not attributable to a specific job is typically treated as an indirect labor cost. Indirect labor is a component of manufacturing overhead. While the regular wage portion is direct labor, the premium portion ($10 per hour in this case) is considered an overhead cost because it benefits production in general, not a specific unit. Both direct labor and manufacturing overhead are product costs.
6. A company incurs costs for depreciation on several assets. Depreciation on factory equipment is $50,000, on sales vehicles is $20,000, and on computers used in the administrative office is $10,000. How should the total depreciation of $80,000 be treated for financial reporting?
   Answer: $50,000 is a product cost; $30,000 is a period cost. The classification of depreciation depends on the asset's function. Depreciation on factory equipment ($50,000) is a cost of production and is therefore a product cost (manufacturing overhead). Depreciation on sales vehicles ($20,000) is a selling expense, and depreciation on administrative computers ($10,000) is an administrative expense. Both selling and administrative expenses are period costs. Thus, the total period cost portion of depreciation is $20,000 + $10,000 = $30,000.
7. A company pays $100,000 per month in rent for a building where 70% of the space is used for manufacturing and 30% is used for sales and administration offices. The company's controller booked the entire $100,000 as a period cost. If 10% of the month's production remains in ending inventory, how did this error affect the company's balance sheet?
   Answer: Total assets are understated by $7,000. The portion of rent related to manufacturing (70% * $100,000 = $70,000) is a product cost. The remaining $30,000 is a period cost. The controller incorrectly expensed the entire $100,000. The $70,000 of product cost should have been capitalized into inventory. Since 10% of production remains in inventory, 10% of this cost, or $7,000, should have been recorded in the Inventory account on the balance sheet. Because it was expensed instead, the Inventory account (an asset) is understated by $7,000.
8. Based on the information provided, what is the total amount of product costs incurred by the company in March?
   Answer: $180,000 Product costs include all costs necessary to bring a product to a finished state. This includes direct materials, direct labor, and manufacturing overhead. In this case, product costs are Direct Materials ($80,000) + Direct Labor ($60,000) + Factory Supervisor Salaries ($25,000) + Depreciation on Factory Equipment ($15,000) = $180,000. Sales commissions, corporate office rent, and advertising are period costs.
9. What is the total product cost that should be used to determine the gross profit on this contract?
   Answer: $182,000 including all costs except post-installation training services Product costs include all costs necessary to get the product ready for its intended use by the customer: electronic components ($85,000), direct labor ($45,000), factory overhead ($12,000), pre-installation testing ($18,000), and installation labor ($22,000) = $182,000. Post-installation training ($8,000) is a period cost because it provides ongoing value to the customer beyond the product itself and represents a separate service component rather than costs to complete the product.
10. If a cost is classified as a product cost rather than a period cost, what is the immediate effect on the financial statements in the period the cost is incurred (assuming the related goods are not yet sold)?
    Answer: Net income is higher and total assets are higher. When a cost is classified as a product cost, it is capitalized as inventory (an asset) on the balance sheet. It is not expensed on the income statement until the goods are sold. If it were classified as a period cost, it would be expensed immediately, reducing net income. Therefore, by classifying it as a product cost, the immediate expense is avoided, resulting in higher net income for the period. The capitalization increases the inventory account, resulting in higher total assets.
11. What is the total amount that should be classified as product costs for this specific order?
    Answer: $26,000 including materials, testing, and shipping costs only Product costs include specialized packaging materials ($15,000), regulatory compliance testing ($8,000), and expedited shipping of materials ($3,000) as these are necessary to get the product ready for sale. The training costs ($4,000) should be treated as a period cost because the training provides future benefits beyond this specific order and is not directly incorporated into the product itself. Total product costs = $15,000 + $8,000 + $3,000 = $26,000.
12. A manufacturing company replaces a significant portion of its direct labor force with highly automated robotic equipment. Which of the following describes the most likely impact on the company's cost structure?
    Answer: Direct labor costs will decrease, and manufacturing overhead costs will increase. Automating a production process replaces direct labor with machinery. This causes a decrease in direct labor costs (a product cost). The costs associated with the new machinery, such as depreciation, power, and maintenance, are all components of manufacturing overhead (also a product cost). Therefore, the shift is within the categories of product costs: from direct labor to manufacturing overhead. There is no direct impact on period costs like selling and administrative expenses.
13. What journal entry is required to correct this error, assuming the books have not yet been closed?
    Answer: Debit Finished Goods Inventory for $10,000 and Cost of Goods Sold for $30,000; Credit Administrative Expense for $40,000. The $40,000 should have been a product cost (MOH). Since it was misclassified, the Administrative Expense account is overstated by $40,000 and must be credited. The product cost should be allocated between units sold and units in ending inventory. The 75% of units sold should have their share of the cost (75% $40,000 = $30,000) expensed as Cost of Goods Sold. The 25% of units in ending inventory should have their share (25% $40,000 = $10,000) capitalized in the Finished Goods Inventory account. Thus, the correction requires a debit to COGS for $30,000 and a debit to Finished Goods Inventory for $10,000.
14. A company manufactures furniture and operates its own delivery fleet. During March, delivery truck expenses included: $8,000 for fuel, $2,000 for truck maintenance, $5,000 for driver wages, and $1,500 for truck insurance. Analysis reveals that 60% of deliveries were for furniture sold in March, 30% for furniture sold in previous months, and 10% for picking up raw materials from suppliers. How should the total $16,500 in delivery costs be classified for March?
    Answer: $1,650 as product cost, $14,850 as period cost for delivery operations When you encounter delivery or transportation costs in cost accounting, the key is determining whether these costs help create the product (product costs) or support selling and administration (period costs). The timing and purpose of each delivery determines the proper classification. Let's analyze the $16,500 in total delivery costs by purpose: 10% ($1,650) was for picking up raw materials, which directly supports manufacturing and should be classified as product cost. The remaining 90% ($14,850) represents deliveries to customers - regardless of when the furniture was manufactured, these are selling expenses that should be classified as period costs. The correct answer is C: $1,650 as product cost and $14,850 as period cost. Only the raw material pickup costs help manufacture the product, while all customer deliveries are selling activities. Answer A incorrectly treats the 60% of deliveries for March sales ($9,900) as cost of goods sold rather than period cost. Customer delivery is a selling expense, not part of the product's manufacturing cost that flows through COGS. Answer B misclassifies all customer deliveries ($9,900) as product costs, when these should be period costs since they occur after manufacturing is complete. Answer D incorrectly includes the March customer deliveries ($9,900) plus the raw material pickups ($1,650) as product costs totaling $11,550, but customer deliveries are selling expenses. Remember: transportation costs are product costs only when they bring materials into production. Once the product is complete, delivery to customers is always a period cost, regardless of when the sale occurred.
15. Based on generally accepted accounting principles for manufacturing companies, how should the R&D costs be classified?
    Answer: $200,000 as period cost since R&D costs cannot be capitalized under GAAP Under generally accepted accounting principles (GAAP), research and development costs must be expensed as period costs when incurred, with very limited exceptions. Even though some activities relate to existing products or manufacturing processes, R&D costs are not considered product costs because they don't directly transform raw materials into finished goods. All $200,000 should be classified as period costs regardless of the specific R&D activities performed.
16. Research and development (R&D) costs for a new product line amounted to $500,000 for a technology company. The company anticipates the new product will generate significant revenue for the next five years. For external financial reporting under U.S. GAAP, how are these R&D costs typically treated?
    Answer: As a period cost, expensed in the period they are incurred. Under U.S. GAAP, research and development costs are generally treated as period costs and expensed as incurred. This is due to the uncertainty of future economic benefits from such expenditures. They are not capitalized into inventory as product costs, nor are they typically capitalized and amortized as an intangible asset (with a few exceptions not relevant here).
17. The salary of a company's chief financial officer (CFO) would be classified as which type of cost?
    Answer: A period cost, because it is an administrative expense. The CFO's salary is a general and administrative expense. It is not related to the manufacturing of a product. All selling, general, and administrative (SG&A) costs are classified as period costs. They are expensed in the period incurred, regardless of the level of production or sales. While the cost can be traced to the finance department, in the context of product vs. period costs, its classification is administrative.
18. From a conceptual standpoint, what is the primary reason that Generally Accepted Accounting Principles (GAAP) requires the differentiation between product and period costs?
    Answer: To properly apply the matching principle by associating production costs with the revenues they generate. The core reason for distinguishing between product and period costs is the matching principle. Product costs are capitalized into inventory and are only expensed (as Cost of Goods Sold) in the period when the related products are sold, thereby matching the expense with the revenue it helped generate. Period costs cannot be directly traced to specific products and are expensed in the period they are incurred.
19. For the period, what is the total amount of period costs that should be expensed as incurred?
    Answer: $28,000 Period costs are not related to the manufacturing process and are expensed in the period they are incurred. These costs are: Freight costs to ship to customers (selling cost) of $15,000 + Depreciation on CEO's car (administrative cost) of $5,000 + Corporate accounting software license (administrative cost) of $8,000 = $28,000. Wood/fabric (direct material), assembly worker wages (direct labor), and the inspector's salary (manufacturing overhead) are all product costs.
20. Based on this information, what is the total amount of conversion costs for the period?
    Answer: $165,000 Conversion costs are the costs incurred to 'convert' direct materials into finished goods. They consist of direct labor and manufacturing overhead. In this case, direct labor is the wages of assembly workers ($100,000). Manufacturing overhead includes the factory manager's salary ($60,000) and lubricants for machinery ($5,000). Therefore, total conversion costs are $100,000 + $60,000 + $5,000 = $165,000. Direct materials are a product cost but are not part of conversion costs; they are part of prime costs.
