Answer Key and Marking Scheme

Paper: SA1 (Version 4)
Total Marks: 60

Section A: Inventory Costing (20 marks)

Question 1: Inventory Valuation Methods (5 marks)

(a) Cost of Goods Sold using FIFO (3 marks)

Working:

Sales on Mar 12: 250 units

From opening inventory (Mar 1): 200 units × $15.00 =$ 3,000
From Mar 5 purchases: 50 units × $16.00 =$ 800
Cost for this sale: $3,800

Remaining after Mar 12 sale:

Mar 5 purchases: 250 units × $16.00

Sales on Mar 25: 350 units

From remaining Mar 5 purchases: 250 units × $16.00 =$ 4,000
From Mar 18 purchases: 100 units × $17.50 =$ 1,750
Cost for this sale: $5,750

Total COGS = $3,800 +$ 5,750 = $9,550

Mark	Description
1	Correct allocation of first sale (200 from opening + 50 from Mar 5)
1	Correct allocation of second sale (250 from Mar 5 + 100 from Mar 18)
1	Correct total COGS of $9,550

(b) Closing Inventory Value using FIFO (2 marks)

Working:

Remaining after all sales:

Mar 18 purchases: 300 units × $17.50 =$ 5,250
Mar 30 purchases: 100 units × $18.00 =$ 1,800

Total closing inventory = $5,250 +$ 1,800 = $7,050

Mark	Description
1	Correct identification of remaining units (300 from Mar 18 + 100 from Mar 30)
1	Correct total closing inventory of $7,050

Question 2: Inventory Valuation Concepts (4 marks)

(a) Accounting Concept (1 mark)

Answer: The prudence (conservatism) concept governs inventory valuation. Inventory should be valued at the lower of cost and net realisable value (NRV) .

Mark	Description
1	Correct statement of prudence concept and/or lower of cost and NRV

(b) Valuation of Damaged Units (3 marks)

Working:

Cost per unit: $18.00
NRV per unit: $10.00 −$ 2.00 = $8.00
Lower of cost and NRV: $8.00 per unit

Answer: The damaged units should be valued at $8.00 per unit (the NRV), as it is lower than the cost of$ 18.00. This follows the prudence concept, which requires that assets are not overstated and losses are recognised as soon as they are foreseen. The write-down of $10.00 per unit ($ 18.00 − $8.00) should be charged as an expense in the Income Statement.

Mark	Description
1	Correct calculation of NRV ( $10.00 −$ 2.00 = $8.00)
1	Correct identification that NRV ( $8.00) is lower than cost ($ 18.00)
1	Explanation linking to prudence concept and treatment as expense

Question 3: Inventory Turnover Analysis (6 marks)

(a) Inventory Turnover Rate Calculation (4 marks)

Sunrise Trading:

Average inventory = ( $45,000 +$ 55,000) ÷ 2 = $50,000
Inventory turnover = $320,000 ÷$ 50,000 = 6.4 times

Horizon Electronics:

Average inventory = ( $52,000 +$ 68,000) ÷ 2 = $60,000
Inventory turnover = $434,000 ÷$ 60,000 = 7.2 times (to 1 d.p.)

Mark	Description
1	Correct average inventory for Sunrise ($50,000)
1	Correct turnover for Sunrise (6.4 times)
1	Correct average inventory for Horizon ($60,000)
1	Correct turnover for Horizon (7.2 times)

(b) Commentary on Efficiency (2 marks)

Answer: Horizon Electronics has a higher inventory turnover rate (7.2 times) compared to Sunrise Trading (6.4 times). This indicates that Horizon is more efficient in managing its inventory, as it sells and replaces its stock more frequently. A higher turnover rate generally means lower holding costs, reduced risk of obsolescence, and better cash flow management. However, Sunrise's rate of 6.4 times is still reasonable, and the difference may be due to factors such as different product mixes, pricing strategies, or market demand.

Mark	Description
1	Correct comparison (Horizon higher/more efficient)
1	Reasoned comment linking turnover to efficiency, holding costs, or cash flow

Question 4: Effect of Inventory Errors (5 marks)

(a) Effect of Error 1 (1 mark)

Answer: Closing inventory overstated → Cost of goods sold understated → Gross profit overstated by $8,000.

Mark	Description
1	Correct statement that gross profit is overstated

(b) Effect of Error 2 (2 marks)

Answer: The purchase of $3,500 was not recorded, so purchases are understated. However, the goods were included in closing inventory, so closing inventory is correct. The effect is:

Purchases understated by $3,500 → COGS understated by$ 3,500
Therefore, gross profit is overstated by $3,500.

Mark	Description
1	Correct identification that purchases are understated
1	Correct conclusion that gross profit is overstated by $3,500

(c) Total Effect on Net Profit (2 marks)

Working:

Error 1: Gross profit overstated by $8,000 → Net profit overstated by$ 8,000
Error 2: Gross profit overstated by $3,500 → Net profit overstated by$ 3,500
Total overstatement: $8,000 +$ 3,500 = $11,500

Answer: Net profit is overstated by $11,500.

Mark	Description
1	Correct addition of both errors ( $8,000 +$ 3,500)
1	Correct conclusion (overstated by $11,500)
