Answers

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

1. General Rule (1m)

Lower of cost and net realisable value (NRV).

2. NRV Definition (2m)

The estimated selling price in the ordinary course of business (1m) minus the estimated costs of completion and the estimated costs necessary to make the sale (1m).

3. Prudence Concept (3m)

Prudence is the practice of not overstating assets or income and not understating liabilities or expenses (1m).
In inventory, this means valuing stock at the lower of cost and NRV (1m).
This ensures that the business does not report a profit that has not yet been realized (1m).

4. FIFO vs AVCO Reasons (2m)

(Any two)
FIFO reflects the actual physical flow of goods for many businesses (e.g., perishables).
FIFO results in a closing inventory value that is closer to current market replacement costs.
Simpler to track for specific batches.

5. Classification (1m)

Current Asset.

6. COGS Calculation (2m)

$4,500 +$ 28,000 - $6,200 =$ 26,300.
(1m for method, 1m for correct answer).

7. Gross Profit Calculation (2m)

$45,000 -$ 26,300 = $18,700.
(1m for method, 1m for correct answer).

8. Inventory Turnover (2m)

$120,000 /$ 15,000 = 8 times.
(1m for method, 1m for correct answer).

9. FIFO Inventory Value (3m)

Total units = 30. Sold = 15. Remaining = 15.
FIFO assumes oldest sold first. Remaining are the newest:
10 units @ $15 (Batch C) =$ 150
5 units @ $12 (Batch B) =$ 60
Total = $210.
(1m for identifying remaining units, 1m for correct batch selection, 1m for total).

10. AVCO Inventory Value (3m)

Total Cost = (1010) + (1012) + (10*15) = $100 +$ 120 + $150 =$ 370.
Average Cost per unit = $370 / 30 units =$ 12.333...
Remaining units = 15.
Value = 15 * $12.333 =$ 185.
(1m for total cost, 1m for average cost, 1m for final value).

11. NRV Application (2m)

Cost = $150.
NRV = $120 -$ 30 = $90.
Lower of $150 and$ 90 is $90.
(1m for NRV calculation, 1m for final value).

12. Net Purchases Calculation (3m)

COGS = Opening + Purchases - Closing
$80,000 =$ 8,000 + Purchases - $12,000
$80,000 = Purchases -$ 4,000
Purchases = $84,000.
(1m for formula, 1m for substitution, 1m for correct answer).

13. Holding Period (2m)

365 days / 6 times = 60.83 days (or 61 days).
(1m for method, 1m for correct answer).

14. Understated Closing Inventory (2m)

Closing inventory $\downarrow$ $\rightarrow$ COGS $\uparrow$ $\rightarrow$ Gross Profit $\downarrow$ .
Gross Profit is understated by $1,000.

15. Overstated Opening Inventory (2m)

Opening inventory $\uparrow$ $\rightarrow$ COGS $\uparrow$ $\rightarrow$ Net Profit $\downarrow$ .
Net Profit is understated by $500.

16. Rising Prices: FIFO vs AVCO (4m)

In rising prices, FIFO assumes the oldest (cheaper) stock is sold first (1m).
Therefore, the closing inventory consists of the most recent (more expensive) purchases (1m).
This results in a higher closing inventory value compared to AVCO (1m).
Consequently, COGS is lower and profit is higher under FIFO (1m).

17. High Turnover Analysis (4m)

Positive: Indicates strong demand, efficient stock management, and lower storage/obsolescence costs (2m).
Negative: May indicate that the business is not stocking enough (understocking), leading to lost sales opportunities (stock-outs) (2m).

18. Non-Accounting Reasons (4m)

(Any two, 2m each)
Product type: Competitor sells fast-moving consumer goods (FMCG), while the business sells luxury/specialized items.
Pricing strategy: Competitor uses a low-price strategy to drive volume.
Supplier lead times: Competitor has "Just-in-Time" delivery, allowing lower stock levels.
Market share/Brand loyalty: Competitor has higher demand.

19. Selling Price Valuation Impact (4m)

Valuation at selling price violates the Prudence concept (1m).
It overstates the value of the asset (inventory) in the SFP (1m).
It understates the COGS in the Income Statement (1m).
This leads to an overstatement of Gross Profit and Net Profit (1m).

20. Falling Prices: AVCO to FIFO (4m)

In falling prices, FIFO assumes the oldest (more expensive) stock is sold first (1m).
This leads to a higher COGS compared to AVCO (1m).
A higher COGS results in a lower Gross Profit (1m).
Therefore, the reported Net Profit will decrease (1m).
