  3. An entity is deciding between FIFO and AVCO. The manager prefers the method that shows a more "stable" cost of sales over time. Which method should be chosen and why? (4)

  4. Explain how the overvaluation of closing inventory in Year 1 affects the profit of Year 2. (4)

Answer Key - Secondary 4 Principles of Accounts Quiz (Inventory Costing)

Section A: Conceptual Understanding

  1. Lower of cost and net realisable value (NRV). (1m)
  2. The estimated selling price minus the estimated costs of completion and the estimated costs necessary to make the sale. (2m)
  3. Prudence Concept. (1m) It ensures that assets and profits are not overstated and liabilities/expenses are not understated. (1m)
  4. FIFO: Assumes the first goods purchased are the first ones sold; closing stock consists of the most recent purchases. (1m) AVCO: Calculates a weighted average cost for all units available; closing stock is valued at this average. (1m)
  5. True. (1m) (In falling prices, FIFO uses the oldest, higher prices for COGS, leaving the newest, lower prices for closing stock).

Section B: Calculations and Application

  1. 4,500+4,500 + 22,000 + 800−800 - 5,200 = $22,100 (3m)
  2. Average Inventory = (12,000+12,000 + 18,000) / 2 = 15,000.Turnover=15,000. Turnover = 120,000 / $15,000 = 8 times per year (3m)
  3. NRV = 550−550 - 20 = 530.TotalValue=10units∗530. Total Value = 10 units * 530 = $5,300 (3m)
  4. Units remaining = (10 + 20) - 15 = 15 units. FIFO: All 15 units come from the Jan 15 batch (@ 12).Value=15∗12). Value = 15 * 12 = $180 (3m)
  5. Total cost = (10 * 10)+(20∗10) + (20 * 12) = 100+100 + 240 = 340.Totalunits=30.Averagecost=340. Total units = 30. Average cost = 340 / 30 = 11.33perunit.ClosingValue=15units∗11.33 per unit. Closing Value = 15 units * 11.33 = $170 (3m)
  6. Closing inventory ↑\uparrow →\rightarrow COGS ↓\downarrow →\rightarrow Gross Profit Overstated by $1,000. (2m)
  7. Opening inventory ↓\downarrow →\rightarrow COGS ↓\downarrow →\rightarrow Net Profit Overstated by $500. (2m)
  8. Possible reasons: Slowdown in demand, overstocking/inefficient purchasing, or a shift to higher-priced items that sell slower. (2m)
  9. Gross Profit = 40% of 50,000=50,000 = 20,000. Cost of Sales = 50,000−50,000 - 20,000 = $30,000 (3m)
  10. Adjustment = 2,000−2,000 - 1,700 = $300. It is an expense (write-down of inventory). (3m)

Section C: Analysis and Synthesis

  1. FIFO yields higher Gross Profit. (1m) In rising prices, FIFO assigns the oldest, cheaper costs to COGS (1m), which reduces the cost of sales (1m) and thus increases the gross profit (1m).
  2. Not always beneficial. (1m) A rate that is too high may indicate "understocking" (1m). This can lead to lost sales opportunities (stock-outs) (1m) and dissatisfied customers (1m).
  3. AVCO. (1m) Because it averages the cost of purchases over time (1m), it smooths out the fluctuations/spikes in purchase prices (1m), resulting in a more stable cost of sales figure compared to FIFO (1m).
  4. Closing inventory of Year 1 becomes the Opening inventory of Year 2. (1m) If Year 1 closing inventory is overstated, Year 2 opening inventory is overstated. (1m) This increases the Cost of Sales for Year 2 (1m), which leads to an understatement of profit in Year 2. (1m)
  5. (a) NRV = 4,800−4,800 - 300 = 4,500.Value=∗∗4,500. Value = **4,500**. (2m) (b) Profit would be overstated (1m) because the asset is recorded at 5,000insteadof5,000 instead of 4,500, failing to recognize a loss of $500. (1m)
