Question 1: Inventory Costing Methods (15 marks)

(a) FIFO Method (perpetual)

(i) Cost of Sales for March 2026 [4 marks]

Date	Sale Units	Cost Calculation	Cost of Sales ($)
Mar 11	100	80 × $15.00 + 20 ×$16.50	1,200 + 330 = 1,530
Mar 21	130	100 × $16.50 + 30 ×$17.00	1,650 + 510 = 2,160
Mar 29	110	120 × $17.00	2,040
Total	340		5,730

Marking: 1 mark for each correct sale calculation (3 marks), 1 mark for correct total.

(ii) Closing Inventory as at 31 March 2026 [2 marks]

Remaining inventory after all sales:

• From Mar 26 purchase: 90 units × $18.00 =$1,620
• From Mar 16 purchase: 0 units remaining (120 − 30 − 90 = 0)
• From Mar 6 purchase: 0 units remaining

Total closing inventory = 90 units valued at $1,620

Marking: 1 mark for identifying correct layers, 1 mark for correct valuation.

(b) AVCO Method (perpetual)

(i) Cost of Sales for March 2026 [4 marks]

Date	Transaction	Units	Unit Cost ($)	Total ($)	AVCO ($)
Mar 1	Opening	80	15.00	1,200	15.00
Mar 6	Purchase	120	16.50	1,980
	Balance	200		3,180	15.90
Mar 11	Sale	(100)	15.90	(1,590)
	Balance	100		1,590	15.90
Mar 16	Purchase	150	17.00	2,550
	Balance	250		4,140	16.56
Mar 21	Sale	(130)	16.56	(2,152.80)
	Balance	120		1,987.20	16.56
Mar 26	Purchase	90	18.00	1,620
	Balance	210		3,607.20	17.18 (rounded)
Mar 29	Sale	(110)	17.18	(1,889.80)
	Balance	100		1,717.40	17.17

Total Cost of Sales = $1,590.00 +$2,152.80 + $1,889.80 = **$5,632.60**

Marking: 1 mark for each correct AVCO calculation after each purchase (3 marks), 1 mark for correct total cost of sales.

(ii) Closing Inventory as at 31 March 2026 [2 marks]

Closing inventory = 100 units × $17.17 = **$1,717.40** (or $1,717 if using unrounded AVCO)

Marking: 1 mark for correct units, 1 mark for correct valuation.

---

(c) Advantage and Disadvantage of FIFO [3 marks]

Advantage (1.5 marks):

• FIFO values closing inventory at the most recent purchase prices, which provides a more current valuation of inventory on the statement of financial position. This is more relevant for decision-making.

Disadvantage (1.5 marks):

• During periods of rising prices, FIFO results in lower cost of sales and higher reported profit compared to AVCO. This may lead to higher tax liabilities and does not reflect current costs in the income statement.

Marking: 1.5 marks for each valid point with explanation. Award 1 mark for stating the point without explanation.

Question 2: Inventory Valuation and Financial Statement Effects (15 marks)

(a) Corrected Closing Inventory [5 marks]

	$
Closing inventory at cost (per books)	28,000
Adjustment 1: Damaged goods write-down
Cost of damaged goods	3,000
Net realisable value: $1,200 −$400 = $800
Write-down required: $3,000 −$800 =	(2,200)
Adjustment 2: Goods in transit (FOB shipping point)
Goods should be included: add	2,500
Adjustment 3: Sale-or-return goods
Goods should be excluded: deduct	(1,800)
Corrected closing inventory	26,500

Marking: 1 mark for each adjustment correctly identified and calculated (3 × 1 mark = 3 marks), 1 mark for correct treatment of each adjustment (add/deduct), 1 mark for correct final figure. Total 5 marks.

(b) Income Statement Extract [4 marks]

Beauty Care Enterprise - Income Statement Extract for the year ended 31 December 2025

	$	$
Revenue		180,000
Less: Cost of Goods Sold:
Opening inventory	22,000
Add: Purchases	95,000
Less: Closing inventory	(26,500)
Cost of Goods Sold		(90,500)
Gross Profit		89,500

Marking: 1 mark for correct revenue, 1 mark for correct opening inventory and purchases, 1 mark for correct closing inventory, 1 mark for correct gross profit.

(c) Prudence Concept Application [3 marks]

The prudence concept requires that assets and profits should not be overstated, and liabilities and expenses should not be understated. In valuing the damaged goods, the business must use the lower of cost ($3,000) and net realisable value ($800). By writing down the inventory to $800, the business recognises an expense of$2,200, which reduces profit. This ensures that the inventory is not overstated on the statement of financial position and profit is not overstated in the income statement. This provides a more cautious and realistic view of the business's financial position.

Marking: 1 mark for stating the prudence concept, 1 mark for explaining lower of cost and NRV, 1 mark for linking to the effect on profit and assets.

(d) Effect on Gross Profit [3 marks]

If the goods ($2,500) were excluded from both purchases and closing inventory:

• Purchases would be understated by $2,500
• Closing inventory would be understated by $2,500
• Cost of sales = Opening inventory + Purchases − Closing inventory
• Effect on cost of sales: −$2,500 (from purchases) − (−$2,500) (from closing inventory) = $0
• Therefore, there is no effect on gross profit.

Marking: 1 mark for identifying the effect on purchases, 1 mark for identifying the effect on closing inventory, 1 mark for concluding no effect on gross profit with explanation.

Question 3: Inventory Management and Decision-Making (15 marks)

(a) Ratio Calculations [6 marks]

(i) Inventory Turnover Ratio [2 marks]

	FreshMart	ValueStore
Average Inventory	($42,000 +$38,000) ÷ 2 = $40,000	($35,000 +$45,000) ÷ 2 = $40,000
Inventory Turnover	$350,000 ÷$40,000 = 8.75 times	$285,000 ÷$40,000 = 7.13 times

Marking: 1 mark for each correct ratio.

(ii) Days Sales in Inventory [2 marks]

	FreshMart	ValueStore
Days Sales in Inventory	365 ÷ 8.75 = 41.71 days	365 ÷ 7.13 = 51.19 days

Marking: 1 mark for each correct calculation (allow rounding differences).

(iii) Trade Payables Turnover Ratio [2 marks]

	FreshMart	ValueStore
Trade Payables Turnover	$346,000 ÷$28,000 = 12.36 times	$295,000 ÷$32,000 = 9.22 times

Marking: 1 mark for each correct ratio.

(b) Comparison and Comment [4 marks]

FreshMart has a higher inventory turnover ratio (8.75 times) compared to ValueStore (7.13 times). This means FreshMart sells and replaces its inventory more frequently. FreshMart's days sales in inventory is 41.71 days, which is lower than ValueStore's 51.19 days. This indicates that FreshMart holds inventory for a shorter period before selling it, suggesting more efficient inventory management.

FreshMart also has a higher trade payables turnover ratio (12.36 times) compared to ValueStore (9.22 times), indicating that FreshMart pays its suppliers more quickly. While this may be favourable for supplier relationships, it could also mean FreshMart is not fully utilising the credit period offered by suppliers.

Overall, FreshMart appears to manage its inventory more efficiently, with faster inventory turnover. However, ValueStore's longer payment period may provide better cash flow management.

Marking: 1 mark for comparing inventory turnover, 1 mark for comparing days sales in inventory, 1 mark for comparing payables turnover, 1 mark for overall conclusion.

(c) Effect of Switching from FIFO to AVCO (Rising Prices) [3 marks]

During a period of rising prices:

1. Cost of sales would increase. Under AVCO, the cost of sales includes a weighted average of older (lower) and newer (higher) costs, resulting in a higher cost of sales compared to FIFO, which uses the oldest (lowest) costs first.

2. Closing inventory value would decrease. Under AVCO, closing inventory is valued at the weighted average cost, which is lower than the most recent (highest) purchase prices used under FIFO. This results in a lower inventory value on the statement of financial position.

Marking: 1.5 marks for each effect with explanation. Award 1 mark for stating the effect without explanation.

(d) Recommendation for ValueStore [2 marks]

ValueStore should implement a just-in-time (JIT) inventory system or reduce order quantities to lower its average inventory holding. This would reduce the days sales in inventory (currently 51.19 days) and improve the inventory turnover ratio. Lower inventory levels would also reduce storage costs and the risk of inventory obsolescence.

Marking: 1 mark for a valid recommendation, 1 mark for justification linked to the ratios or business context.

Question 4: Integrated Inventory Scenario (15 marks)

(a) Corrected Closing Inventory [4 marks]

	$
Closing inventory at cost (per books)	41,000
Adjustment 1: Obsolete inventory write-down
Cost of obsolete items	5,000
NRV (scrap value)	800
Write-down: $5,000 −$800 =	(4,200)
Adjustment 2: Goods in transit (FOB destination)
Goods should be excluded (not yet received)	(6,000)
Adjustment 3: Sale-or-return goods
Already correctly excluded	0
Corrected closing inventory	30,800

Marking: 1 mark for each adjustment (obsolete write-down, FOB destination exclusion), 1 mark for correct amounts, 1 mark for correct final figure.

(b) Corrected Cost of Sales [4 marks]

	$
Opening inventory	35,000
Add: Purchases	160,000
Less: Goods in transit (FOB destination)	(6,000)
Corrected purchases	154,000
Add: Carriage inwards	4,500
Add: Import duties on purchases	2,800
Cost of goods available for sale	196,300
Less: Corrected closing inventory	(30,800)
Corrected cost of sales	165,500

Marking: 1 mark for corrected purchases, 1 mark for including carriage inwards and import duties, 1 mark for correct cost of goods available, 1 mark for correct cost of sales.

(c) Inventory Account [4 marks]

Inventory Account

Date	Details	$	Date	Details	$
Jul 1	Balance b/d	35,000	Jun 30	Cost of Sales	165,500
Jun 30	Purchases	154,000	Jun 30	Inventory write-down	4,200
Jun 30	Carriage inwards	4,500	Jun 30	Balance c/d	30,800
Jun 30	Import duties	2,800
		196,300			200,500

Note: The write-down of $4,200 is shown as a credit to reduce the inventory value. Alternatively, it could be included in cost of sales.

Marking: 1 mark for correct opening balance, 1 mark for correct debit entries, 1 mark for correct credit entries, 1 mark for correct closing balance c/d.

(d) Accounting Concept and Action [3 marks]

Accounting Concept (1.5 marks): The prudence concept requires that assets should not be overstated. Obsolete inventory has a net realisable value lower than its cost. Writing down the inventory to its NRV ensures that the inventory is not overstated on the statement of financial position and that the loss is recognised in the income statement.

Action to Reduce Obsolescence (1.5 marks): The business could implement a first-expired-first-out (FEFO) inventory management system or improve demand forecasting to order inventory quantities that match expected sales. This would reduce the risk of holding excess inventory that may become obsolete.

Marking: 1.5 marks for correctly identifying and explaining the concept, 1.5 marks for a valid action with explanation.
