Answer Key - Secondary 4 Principles of Accounts Quiz: Inventory Costing

Section A: Foundational Concepts

Lower of cost and net realisable value (NRV). (1m)
NRV is the estimated selling price minus the estimated costs of completion and the estimated costs necessary to make the sale. (2m)
FIFO assumes the oldest stock is sold first. It is useful for businesses selling perishable goods or items with short life cycles to ensure stock is rotated. (2m)
Current Assets are overstated. (1m)
False. (In falling prices, FIFO (older, higher costs) results in lower closing inventory than AVCO). (1m)

Section B: Application and Calculation

NRV = $110 -$ 15 = $95. Cost =$ 120. Lower is $95. (2m)
$4,000 +$ 25,000 + $800 -$ 5,500 = $24,300. (3m)
$120,000 /$ 15,000 = 8 times. (2m)
365 days / 4 = 91.25 days. (2m)
Closing inventory understated $\rightarrow$ COGS overstated $\rightarrow$ Gross Profit understated by $2,000. (2m)
Total units = 10 + 20 + 10 = 40. Sold 15. Remaining = 25. FIFO: 10 units @ $8 + 15 units @$ 7 = $80 +$ 105 = $185. (3m)
Total cost = (105) + (207) + (10*8) = 50 + 140 + 80 = $270. Total units = 40. Avg cost =$ 270 / 40 = $6.75 per unit. Closing inventory = 25 units *$ 6.75 = $168.75. (3m)
FIFO ( $185 >$ 168.75). (1m)
AVCO smooths out price fluctuations by averaging costs, preventing sudden jumps in COGS when a single expensive batch is sold. (2m)
Gross Profit Margin = 30%, so COGS = 70% of Revenue. $60,000 = 0.70 * Revenue. Revenue =$ 60,000 / 0.7 = $85,714.29. (3m)

Section C: Analysis and Evaluation

Net Profit will increase. (1m) In rising prices, FIFO assigns the oldest (cheaper) costs to COGS. (1m) This results in a lower COGS compared to AVCO. (1m) Lower COGS leads to higher Gross Profit and subsequently higher Net Profit. (1m)
Entity A is more efficient. (1m) A turnover of 12 times suggests stock is sold and replaced monthly, reducing storage costs and risk of obsolescence. (2m) Entity B (4 times) holds stock longer, potentially tying up liquidity and increasing risk of damage/expiry. (1m)
The suggestion is unethical/incorrect. (1m) It violates the Prudence Concept. (1m) Valuing at replacement cost (if higher than cost/NRV) would overstate assets and profit. (1m) This misleads stakeholders regarding the business's actual financial health. (1m)
Reason 1: Change in fashion trends/consumer taste (e.g., a specific style becomes unpopular, leaving dead stock). (2m) Reason 2: Entry of a new competitor with lower prices, reducing the demand for the store's current inventory. (2m)
AVCO. (1m) AVCO uses a weighted average of all purchases. (1m) This prevents the "shocks" to the income statement that occur in FIFO when very old, very cheap stock is finally cleared and replaced by expensive new stock. (2m)
