Answer Key and Marking Scheme – Version 3 of 5

Subject: Principles of Accounts Level: Secondary 4 Total Marks: 60


Question 1: Inventory Valuation Concepts (12 marks)

(a) State the basis on which inventory should be valued in the financial statements. (2 marks)

Answer: Inventory should be valued at the lower of cost and net realisable value (NRV).

Marking:

  • 1 mark for "lower of cost and net realisable value" or equivalent wording.
  • 1 mark for correctly identifying both cost and NRV as the two components.

(b) Explain the accounting concept that supports the valuation basis stated in part (a). (3 marks)

Answer: The accounting concept is prudence (conservatism). This concept requires that:

  • Assets should not be overstated in the financial statements.
  • Losses should be recognised as soon as they are foreseen.
  • By valuing inventory at the lower of cost and NRV, the business ensures that inventory is not carried at an amount higher than what it expects to recover from its sale. Any anticipated loss (where NRV is below cost) is recognised immediately.

Marking:

  • 1 mark for identifying the prudence/conservatism concept.
  • 1 mark for explaining that assets should not be overstated.
  • 1 mark for linking the concept to inventory valuation (recognising losses when NRV < cost).

(c) Calculate the total value of closing inventory. (4 marks)

Answer:

ItemCost ($)NRV ($)Lower of Cost and NRV ($)
A5,0006,2005,000
B3,8003,1003,100
C7,2007,2007,200
D2,5002,9002,500

Total closing inventory = 5,000+5,000 + 3,100 + 7,200+7,200 + 2,500 = $17,800

Marking:

  • 1 mark for correctly applying the lower of cost and NRV to each item (award if at least 3 of 4 are correct).
  • 1 mark for correct individual valuations for all four items.
  • 1 mark for correct addition.
  • 1 mark for final answer of $17,800.

(d) Explain why item B is valued differently from item A in your calculation above. (3 marks)

Answer: Item A is valued at cost (5,000)becauseitscostislowerthanitsNRV(5,000) because its cost is lower than its NRV (6,200). Under the prudence concept, the business does not anticipate profits, so it uses the lower cost figure.

Item B is valued at NRV (3,100)becauseitsNRVislowerthanitscost(3,100) because its NRV is lower than its cost (3,800). This means the business expects to recover less than the cost of the item. Under the prudence concept, the loss must be recognised immediately by writing down the inventory to its NRV.

Marking:

  • 1 mark for explaining why item A is valued at cost (cost < NRV, no profit anticipated).
  • 1 mark for explaining why item B is valued at NRV (NRV < cost, loss recognised).
  • 1 mark for linking both explanations to the prudence concept.

Question 2: Inventory Costing Methods (16 marks)

(a) FIFO Method

(i) Cost of goods sold for March 2025 (4 marks)

Answer:

Sale on 15 March (250 units):

  • 200 units from opening inventory @ 15.00=15.00 = 3,000
  • 50 units from 8 March purchases @ 18.00=18.00 = 900
  • Cost of first sale = $3,900

Sale on 28 March (350 units):

  • Remaining from 8 March purchases: 250 units @ 18.00=18.00 = 4,500
  • 100 units from 22 March purchases @ 20.00=20.00 = 2,000
  • Cost of second sale = $6,500

Total Cost of Goods Sold = 3,900+3,900 + 6,500 = $10,400

Marking:

  • 1 mark for correct allocation of first sale (200 @ 15,50@15, 50 @ 18).
  • 1 mark for correct cost of first sale ($3,900).
  • 1 mark for correct allocation of second sale (250 @ 18,100@18, 100 @ 20).
  • 1 mark for correct total COGS ($10,400).

(ii) Value of closing inventory as at 31 March 2025 (2 marks)

Answer: Remaining from 22 March purchases: 300 units @ 20.00=20.00 = **6,000**

Marking:

  • 1 mark for identifying remaining units (300).
  • 1 mark for correct valuation ($6,000).

(b) Weighted Average Cost (AVCO) Method

(i) Weighted average cost per unit after the purchase on 8 March 2025 (2 marks)

Answer: Total cost before 8 March = 200 × 15.00=15.00 = 3,000 Purchase on 8 March = 300 × 18.00=18.00 = 5,400 Total cost = 3,000+3,000 + 5,400 = 8,400Totalunits=200+300=500Weightedaveragecost=8,400 Total units = 200 + 300 = 500 Weighted average cost = 8,400 ÷ 500 = $16.80 per unit

Marking:

  • 1 mark for correct total cost and total units.
  • 1 mark for correct average cost ($16.80).

(ii) Weighted average cost per unit after the purchase on 22 March 2025 (3 marks)

Answer: After sale on 15 March (250 units): Remaining units = 500 − 250 = 250 units Remaining cost = 250 × 16.80=16.80 = 4,200

Purchase on 22 March = 400 × 20.00=20.00 = 8,000 Total cost = 4,200+4,200 + 8,000 = 12,200Totalunits=250+400=650Weightedaveragecost=12,200 Total units = 250 + 400 = 650 Weighted average cost = 12,200 ÷ 650 = $18.77 per unit (rounded to 2 d.p.)

Marking:

  • 1 mark for correct remaining units and cost after first sale.
  • 1 mark for correct total cost and total units after 22 March purchase.
  • 1 mark for correct average cost ($18.77).

(iii) Cost of goods sold for March 2025 (3 marks)

Answer: First sale (15 March): 250 units × 16.80=16.80 = 4,200 Second sale (28 March): 350 units × 18.77=18.77 = 6,569.50 Total COGS = 4,200+4,200 + 6,569.50 = $10,769.50

Marking:

  • 1 mark for correct cost of first sale ($4,200).
  • 1 mark for correct cost of second sale ($6,569.50).
  • 1 mark for correct total COGS ($10,769.50). Accept minor rounding differences.

(c) In a period of rising prices, which method (FIFO or AVCO) results in a higher reported profit? Explain your answer. (2 marks)

Answer: FIFO results in a higher reported profit.

Explanation: In a period of rising prices, FIFO charges the older, lower-cost inventory to cost of goods sold first, leaving the newer, higher-cost inventory in closing inventory. This results in a lower cost of goods sold and therefore a higher gross profit compared to AVCO, which averages out the costs.

Marking:

  • 1 mark for identifying FIFO.
  • 1 mark for correct explanation (lower COGS due to older, cheaper costs being charged first).

Question 3: Inventory Errors and Their Effects (14 marks)

(a) Effects of errors:

Error 1: Closing inventory overstated by $4,500

Effect
(i) Cost of goods soldUnderstated by $4,500
(ii) Gross profitOverstated by $4,500
(iii) Net profitOverstated by $4,500

Error 2: Purchase of $2,800 not recorded, but goods included in closing inventory

Effect
(i) Cost of goods soldNo effect (purchases understated by 2,800,butclosinginventoryoverstatedby2,800, but closing inventory overstated by 2,800; effects cancel out in COGS calculation)
(ii) Gross profitNo effect
(iii) Net profitNo effect

Marking:

  • 1 mark each for correct effect on COGS, gross profit, and net profit for Error 1 (3 marks total).
  • 1 mark each for correct effect on COGS, gross profit, and net profit for Error 2 (3 marks total).
  • Award marks for "no effect" where applicable.

(b) Calculate the adjusted net profit after correcting both errors. (4 marks)

Answer: Reported net profit = $52,000

Error 1: Closing inventory overstated → COGS understated → Profit overstated by 4,500.Correction:Deduct4,500. Correction: Deduct 4,500 from profit.

Error 2: No effect on profit (effects cancel out).

Adjusted net profit = 52,00052,000 − 4,500 = $47,500

Marking:

  • 1 mark for identifying that Error 1 overstated profit by $4,500.
  • 1 mark for identifying that Error 2 has no effect on profit.
  • 1 mark for correct adjustment (subtract $4,500).
  • 1 mark for correct final answer ($47,500).

(c) Explain why it is important for a business to ensure that its inventory records are accurate. Provide two reasons. (4 marks)

Answer:

  1. Accurate financial reporting: Inventory is a significant current asset on the statement of financial position. Errors in inventory valuation affect the cost of goods sold, gross profit, and net profit reported in the income statement. Inaccurate records lead to misleading financial statements, which can affect decisions made by management, investors, and creditors.

  2. Effective inventory management: Accurate inventory records help the business monitor stock levels, avoid stock-outs (which lead to lost sales), and prevent overstocking (which ties up cash and increases storage costs). This supports efficient working capital management and helps maintain customer satisfaction.

Marking:

  • 2 marks for each well-explained reason (up to 4 marks).
  • Award 1 mark for a valid point without full explanation.

Question 4: Inventory Analysis and Decision-Making (18 marks)

(a) Calculations:

(i) Cost of goods sold (4 marks)

Answer:

Alpha Trading: COGS = Opening Inventory + Purchases − Closing Inventory = 32,000+32,000 + 310,000 − 38,000=38,000 = **304,000**

Beta Trading: COGS = 28,000+28,000 + 240,000 − 22,000=22,000 = **246,000**

Marking:

  • 1 mark for correct formula or approach for each business.
  • 1 mark for correct COGS for Alpha ($304,000).
  • 1 mark for correct COGS for Beta ($246,000).
  • 1 mark for showing workings.

(ii) Gross profit (2 marks)

Answer:

Alpha Trading: Gross Profit = Revenue − COGS = 480,000480,000 − 304,000 = $176,000

Beta Trading: Gross Profit = 360,000360,000 − 246,000 = $114,000

Marking:

  • 1 mark for correct gross profit for Alpha ($176,000).
  • 1 mark for correct gross profit for Beta ($114,000).

(iii) Gross profit margin (to two decimal places) (2 marks)

Answer:

Alpha Trading: GPM = (176,000÷176,000 ÷ 480,000) × 100% = 36.67%

Beta Trading: GPM = (114,000÷114,000 ÷ 360,000) × 100% = 31.67%

Marking:

  • 1 mark for correct GPM for Alpha (36.67%).
  • 1 mark for correct GPM for Beta (31.67%).
  • Accept answers rounded to two decimal places.

(b) Inventory turnover rate (in times per year) (4 marks)

Answer:

Alpha Trading: Average Inventory = (32,000+32,000 + 38,000) ÷ 2 = 35,000InventoryTurnover=35,000 Inventory Turnover = 304,000 ÷ $35,000 = 8.69 times

Beta Trading: Average Inventory = (28,000+28,000 + 22,000) ÷ 2 = 25,000InventoryTurnover=25,000 Inventory Turnover = 246,000 ÷ $25,000 = 9.84 times

Marking:

  • 1 mark for correct average inventory for Alpha ($35,000).
  • 1 mark for correct turnover for Alpha (8.69 times).
  • 1 mark for correct average inventory for Beta ($25,000).
  • 1 mark for correct turnover for Beta (9.84 times).

(c) Compare and comment on the inventory management of Alpha Trading and Beta Trading. (4 marks)

Answer: Comparison of inventory turnover: Beta Trading has a higher inventory turnover rate (9.84 times) compared to Alpha Trading (8.69 times). This indicates that Beta Trading sells its inventory more quickly.

Comparison of profitability: Alpha Trading has a higher gross profit margin (36.67%) compared to Beta Trading (31.67%). This suggests that Alpha Trading earns more gross profit per dollar of sales, possibly due to higher selling prices or lower purchase costs per unit.

Commentary: Beta Trading's higher inventory turnover suggests efficient inventory management, with less cash tied up in inventory and lower holding costs. However, its lower gross profit margin may indicate that it is selling at lower prices to achieve faster turnover. Alpha Trading, while having a slower turnover, maintains a higher profit margin, which may reflect a different business strategy (e.g., premium pricing). Both approaches have merits depending on the business's overall strategy.

Marking:

  • 1 mark for comparing turnover rates with interpretation.
  • 1 mark for comparing gross profit margins with interpretation.
  • 1 mark for linking turnover to efficiency/cash management.
  • 1 mark for balanced commentary considering both businesses' strategies.

(d) Suggest one way in which Beta Trading could improve its inventory management. (2 marks)

Answer: Beta Trading could review its pricing strategy to improve its gross profit margin. While its inventory turnover is high, the lower margin suggests it may be underpricing its goods. By gradually increasing selling prices (if market conditions allow) or negotiating better purchase prices with suppliers, Beta Trading could improve profitability without significantly affecting its efficient inventory turnover.

Alternative answer: Beta Trading could review its product mix to focus on higher-margin items, or implement better inventory control systems to reduce any potential stock-outs that may be limiting sales.

Marking:

  • 1 mark for a valid suggestion.
  • 1 mark for explaining how the suggestion would improve inventory management or overall performance.
