Mar 6	Purchase	(80 × $15.00 + 120 ×$ 16.50) ÷ 200	15.90
		= ( $1,200 +$ 1,980) ÷ 200 = $3,180 ÷ 200

Remaining Units	AVCO per unit ($)	Value ($)
120	17.32	2,078.40

Marking:

Correct AVCO per unit at end: 1 mark
Correct closing inventory value: 1 mark

Question 2: Inventory Valuation Concepts and Effects (8 marks)

(a) Accounting concept (1 mark)

Answer: Prudence concept (or Conservatism concept).

Marking: 1 mark for correct concept.

(b) Damaged inventory valuation (3 marks)

Calculation	$
Net Realisable Value (NRV) = Selling price − Costs to complete and sell
NRV = $12.00 −$ 3.00	9.00
Cost = $18.00
Lower of cost and NRV = $9.00 per unit
Value of 10 damaged units = 10 × $9.00	90.00

Marking:

Correct NRV calculation: 1 mark
Correct application of lower of cost and NRV: 1 mark
Correct final value: 1 mark

(c) Effect of incorrect valuation (2 marks)

Answer:

Gross profit would be overstated by $90 (the difference between$ 180 and $90). This is because closing inventory would be overstated, reducing cost of sales and increasing gross profit. (1 mark)
Closing inventory would be overstated by $90 (recorded at$ 180 instead of $90). (1 mark)

Marking: 1 mark for each correct effect with explanation.

(d) FIFO vs AVCO during rising prices (2 marks)

(i) Closing inventory valuation: FIFO results in a higher closing inventory valuation than AVCO because FIFO assigns the most recent (higher) costs to closing inventory, while AVCO averages all costs. (1 mark)

(ii) Gross profit: FIFO results in a higher gross profit than AVCO because FIFO assigns older (lower) costs to cost of sales, resulting in lower cost of sales and higher gross profit. (1 mark)

Marking: 1 mark for each correct comparison with explanation.

Marking Scheme (16 marks):

Purchases correctly included: 1 mark
Closing inventory correctly adjusted (W1): 2 marks
Cost of goods sold correctly calculated: 1 mark
Gross profit correctly calculated: 1 mark
Salaries correctly adjusted for accrual: 1 mark

Allowance for doubtful debts correctly handled (W4): 1 mark
Total expenses correctly calculated: 1 mark
Net profit correctly calculated: 1 mark

(b) Treatment of Damaged Goods (4 marks)

Answer: The damaged goods should be valued at the lower of cost and net realisable value (NRV), in accordance with the prudence concept. (1 mark)

The prudence concept requires that assets and profits should not be overstated, and liabilities and expenses should not be understated. (1 mark)
The cost of the damaged goods is $1,200. The NRV is$ 800 (selling price). (1 mark)
Therefore, the damaged goods should be included in closing inventory at $800, not$ 1,200. The write-down of $400 ($ 1,200 − $800) reduces closing inventory, increases cost of sales, and reduces gross profit. (1 mark)

Marking:

Correct identification of prudence concept and lower of cost/NRV: 1 mark
Explanation of prudence concept: 1 mark
Correct identification of cost and NRV: 1 mark
Correct explanation of effect on financial statements: 1 mark

Question 4: Ratio Analysis and Decision-Making (20 marks)

(a)(i) Gross Profit Margin (2 marks)

	Shop A	Shop B
Gross Profit	$500,000 −$ 350,000 = $150,000	$420,000 −$ 273,000 = $147,000
Gross Profit Margin	( $150,000 ÷$ 500,000) × 100 = 30.00%	( $147,000 ÷$ 420,000) × 100 = 35.00%

Marking: 1 mark for each correct calculation.

(a)(ii) Inventory Turnover Ratio (2 marks)

	Shop A	Shop B
Average Inventory	( $40,000 +$ 50,000) ÷ 2 = $45,000	( $35,000 +$ 28,000) ÷ 2 = $31,500
Inventory Turnover	$350,000 ÷$ 45,000 = 7.78 times	$273,000 ÷$ 31,500 = 8.67 times

Marking: 1 mark for each correct calculation (including correct average inventory).

(a)(iii) Days Sales in Inventory (2 marks)

	Shop A	Shop B
Days Sales in Inventory	365 ÷ 7.78 = 46.92 days	365 ÷ 8.67 = 42.10 days

Marking: 1 mark for each correct calculation (accept answers based on candidate's turnover ratio).

(a)(iv) Current Ratio (2 marks)

	Shop A	Shop B
Current Ratio	$120,000 ÷$ 60,000 = 2.00 : 1	$95,000 ÷$ 50,000 = 1.90 : 1

Marking: 1 mark for each correct calculation.

(a)(v) Quick Ratio (2 marks)

	Shop A	Shop B
Quick Assets	$120,000 −$ 50,000 = $70,000	$95,000 −$ 28,000 = $67,000
Quick Ratio	$70,000 ÷$ 60,000 = 1.17 : 1	$67,000 ÷$ 50,000 = 1.34 : 1

Marking: 1 mark for each correct calculation (including correct quick assets).

(b) Evaluation of Inventory Management (4 marks)

Answer should include:

Shop A:

Higher days sales in inventory (46.92 days) indicates inventory is held for longer before being sold.
This may suggest slower-moving inventory or overstocking, which ties up cash and increases storage costs.
However, higher inventory levels contribute to a stronger current ratio (2.00) and provide a buffer against stockouts.

Shop B:

Lower days sales in inventory (42.10 days) indicates more efficient inventory management – inventory is converted to sales more quickly.
This improves cash flow and reduces holding costs.
However, the lower inventory level results in a slightly weaker current ratio (1.90) and lower quick ratio (1.34 vs 1.17 for Shop A – note: Shop B actually has a better quick ratio, indicating better liquidity when inventory is excluded).

Overall evaluation:

Shop B manages its inventory more efficiently, with faster turnover and better liquidity when excluding inventory.
Shop A holds higher inventory levels, which may indicate inefficiency or a deliberate strategy to ensure product availability.
Shop B's approach appears more effective as it achieves higher gross profit margin (35%) with lower inventory investment.

Marking:

Correct comparison of days sales in inventory: 1 mark
Discussion of implications for each shop: 1 mark
Link to liquidity ratios: 1 mark
Reasoned overall evaluation: 1 mark

(c)(i) Effect of Changing to AVCO (2 marks)

Answer: During a period of rising prices, changing from FIFO to AVCO would:

Increase cost of sales because AVCO uses a weighted average that includes more recent higher costs, compared to FIFO which uses older lower costs first. (1 mark)
Decrease closing inventory because AVCO values closing inventory at an average cost that is lower than the most recent purchase prices used by FIFO. (1 mark)

Marking: 1 mark for each correct effect with explanation.

(c)(ii) Recommendation on Changing to AVCO (4 marks)

Answer should include a clear recommendation with two justified reasons:

Recommendation: Shop A should not change to AVCO / should remain with FIFO. (or valid alternative with justification)

Reason 1: FIFO provides a more current valuation of closing inventory on the statement of financial position, as it reflects the most recent purchase prices. This gives a more realistic picture of the business's assets. (2 marks)

Reason 2: During rising prices, FIFO results in higher reported profit, which may be beneficial for attracting investors or obtaining bank loans. Changing to AVCO would reduce reported profit, which could negatively affect stakeholders' perception of the business. (2 marks)

Alternative valid reasons:

FIFO is simpler to apply and understand, reducing administrative complexity.
AVCO smooths out price fluctuations, providing more stable profit figures over time.
Consistency concept: changing methods may reduce comparability between accounting periods.
Tax implications: lower profit under AVCO may result in lower tax (if applicable).

Marking:

Clear recommendation stated: 1 mark
First justified reason with explanation: 1.5 marks
Second justified reason with explanation: 1.5 marks
