Answer Key and Marking Scheme (Version 1)

Subject: Principles of Accounts Level: Secondary 4 Paper: Practice Paper 1 (Version 1 of 5) Total Marks: 60


Question 1: Inventory Costing Methods (15 marks)

(a) (i) Cost of goods sold using FIFO (4 marks)

Sales DateUnits SoldCost AllocationAmount
Mar 15250200 units @ 5.00+50units@5.00 + 50 units @ 5.501,000+1,000 + 275 = $1,275
Mar 28350250 units @ 5.50+100units@5.50 + 100 units @ 6.001,375+1,375 + 600 = $1,975
Total COGS$3,250

Marking:

  • Correct allocation of first sale (200 @ 5.00,50@5.00, 50 @ 5.50): 1 mark
  • Correct calculation of first sale amount ($1,275): 1 mark
  • Correct allocation of second sale (250 @ 5.50,100@5.50, 100 @ 6.00): 1 mark
  • Correct total COGS ($3,250): 1 mark

(a) (ii) Closing inventory using FIFO (2 marks)

After all sales, remaining units: 400 − 100 = 300 units @ 6.00=6.00 = 1,800

Marking:

  • Correct identification of remaining units (300 @ $6.00): 1 mark
  • Correct value ($1,800): 1 mark

(b) (i) Weighted average cost after 22 March purchase (3 marks)

DateUnitsUnit CostTotal Cost
Mar 1200$5.00$1,000
Mar 8300$5.50$1,650
Mar 15 Sale(250)
Balance after sale250
Mar 22400$6.00$2,400

Total cost before 22 March = (250 units × 5.30)=5.30) = 1,325 Weighted average after 22 March = (1,325+1,325 + 2,400) ÷ (250 + 400) = 3,725÷650=3,725 ÷ 650 = 5.73 (rounded to 2 d.p.)

Marking:

  • Correct calculation of cost after first sale (1,325orweightedaverage1,325 or weighted average 5.30): 1 mark
  • Correct total cost after 22 March purchase ($3,725): 1 mark
  • Correct weighted average cost ($5.73): 1 mark

(b) (ii) Closing inventory using AVCO (2 marks)

Units remaining after 28 March sale: 650 − 350 = 300 units Closing inventory = 300 × 5.73=5.73 = 1,719

Marking:

  • Correct remaining units (300): 1 mark
  • Correct value ($1,719): 1 mark

(c) Explanation of profit difference (2 marks)

In a period of rising prices, FIFO will result in a higher reported profit. This is because FIFO charges the older, lower-cost inventory to cost of goods sold first, resulting in a lower COGS and therefore a higher gross profit. AVCO averages all costs, resulting in a COGS that falls between the FIFO and LIFO extremes.

Marking:

  • Correct identification of FIFO as higher profit: 1 mark
  • Clear explanation linking lower COGS to higher profit: 1 mark

(d) Advantage of FIFO (2 marks)

One advantage of FIFO is that the closing inventory value on the statement of financial position reflects the most recent purchase prices, providing a more current valuation of inventory that is closer to replacement cost.

Marking:

  • Any valid advantage stated clearly: 2 marks
  • Accept: FIFO is simple to understand and apply; FIFO reflects the actual physical flow of goods for many businesses; FIFO provides a more realistic inventory valuation during inflation.

Question 2: Inventory Errors and Adjustments (15 marks)

(a) (i) Effect on Cost of Goods Sold (4 marks)

ErrorEffect on COGSExplanation
1. Closing inventory overstated by $3,200Understated by $3,200COGS = Opening + Purchases − Closing; higher closing = lower COGS
2. Purchase recorded but goods not in closing inventoryOverstated by $1,800Purchases included but closing inventory understated
3. Goods sold but still in closing inventoryUnderstated by $2,500Closing inventory overstated, so COGS understated
4. Opening inventory understated by $1,500Understated by $1,500Lower opening inventory = lower COGS

Marking: 1 mark for each correct effect with brief explanation.

(a) (ii) Effect on Net Profit (4 marks)

ErrorEffect on Net ProfitExplanation
1. Closing inventory overstatedOverstated by $3,200Understated COGS → overstated gross profit → overstated net profit
2. Purchase recorded but goods not in closing inventoryUnderstated by $1,800Overstated COGS → understated gross profit → understated net profit
3. Goods sold but still in closing inventoryOverstated by $2,500Understated COGS → overstated gross profit → overstated net profit
4. Opening inventory understatedOverstated by $1,500Understated COGS → overstated gross profit → overstated net profit

Marking: 1 mark for each correct effect with brief explanation.

(b) Corrected Net Profit Statement (5 marks)

$
Draft Net Profit48,000
Add: Overstatement of closing inventory (Error 1)(3,200)
Add: Purchase not in closing inventory (Error 2)(1,800)
Less: Goods sold but in closing inventory (Error 3)2,500
Less: Understatement of opening inventory (Error 4)1,500
Corrected Net Profit47,000

Marking:

  • Correct starting point ($48,000): 1 mark
  • Correct adjustment for Error 1 (−$3,200): 1 mark
  • Correct adjustment for Error 2 (−$1,800): 1 mark
  • Correct adjustment for Error 3 (+$2,500): 1 mark
  • Correct adjustment for Error 4 (+1,500)andcorrectfinalanswer(1,500) and correct final answer (47,000): 1 mark

(c) Importance of accurate inventory valuation (2 marks)

Accurate inventory valuation is important because inventory directly affects both the cost of goods sold (and therefore net profit) and the value of current assets on the statement of financial position. Errors in inventory valuation can mislead users of financial statements about the business's profitability and financial position, leading to poor decision-making.

Marking:

  • Reference to impact on profit/COGS: 1 mark
  • Reference to impact on financial position or decision-making: 1 mark

Question 3: Inventory Turnover and Analysis (15 marks)

(a) (i) Inventory Turnover Rate (4 marks)

Alpha Retail: Average Inventory = (30,000+30,000 + 50,000) ÷ 2 = 40,000InventoryTurnover=40,000 Inventory Turnover = 240,000 ÷ $40,000 = 6 times

Beta Stores: Average Inventory = (50,000+50,000 + 70,000) ÷ 2 = 60,000InventoryTurnover=60,000 Inventory Turnover = 420,000 ÷ $60,000 = 7 times

Marking:

  • Correct average inventory for Alpha ($40,000): 1 mark
  • Correct turnover for Alpha (6 times): 1 mark
  • Correct average inventory for Beta ($60,000): 1 mark
  • Correct turnover for Beta (7 times): 1 mark

(a) (ii) Gross Profit Margin (4 marks)

Alpha Retail: Gross Profit Margin = (160,000÷160,000 ÷ 400,000) × 100% = 40.0%

Beta Stores: Gross Profit Margin = (180,000÷180,000 ÷ 600,000) × 100% = 30.0%

Marking:

  • Correct formula and workings for Alpha: 1 mark
  • Correct answer for Alpha (40.0%): 1 mark
  • Correct formula and workings for Beta: 1 mark
  • Correct answer for Beta (30.0%): 1 mark

(b) Comparison and commentary (3 marks)

Beta Stores has a higher inventory turnover rate of 7 times compared to Alpha Retail's 6 times. This means Beta Stores sells and replaces its inventory more frequently during the year.

A higher inventory turnover rate suggests that Beta Stores is more efficient in managing its inventory. It holds inventory for a shorter period, which reduces storage costs, lowers the risk of obsolescence, and frees up cash that would otherwise be tied up in inventory.

However, Alpha Retail has a significantly higher gross profit margin (40.0% vs 30.0%), which may indicate that Alpha Retail adopts a strategy of higher mark-ups but slower inventory movement, while Beta Stores may focus on higher sales volume with lower margins.

Marking:

  • Correct comparison of rates: 1 mark
  • Interpretation linking turnover to efficiency: 1 mark
  • Insight linking turnover to profit margin or business strategy: 1 mark

(c) Reasons for improvement in Alpha Retail's turnover (2 marks)

Possible reasons include:

  1. Improved demand for Alpha Retail's products, leading to faster sales.
  2. Better inventory management, such as reducing overstocking or discontinuing slow-moving items.
  3. More effective marketing or promotional strategies that increased sales volume.
  4. Improved supplier relationships allowing more frequent, smaller deliveries.

Marking: 1 mark for each valid reason (maximum 2 marks).

(d) Limitation of inventory turnover rate (2 marks)

One limitation is that the inventory turnover rate does not consider the profitability of inventory sales. A business could have a high turnover rate by selling goods at very low margins or even at a loss, which would not be sustainable. Therefore, the turnover rate should be analysed together with profitability ratios such as gross profit margin.

Marking:

  • Clear statement of a valid limitation: 1 mark
  • Explanation of why it is a limitation: 1 mark
  • Accept: Does not account for industry differences; can be distorted by seasonal inventory levels; uses average inventory which may not reflect actual inventory levels throughout the year.

Question 4: Inventory Valuation Concepts and Decision-Making (15 marks)

(a) Accounting concept (1 mark)

The accounting concept is prudence (conservatism).

Marking: 1 mark for correct concept.

(b) Valuation of each inventory item (6 marks)

Model X Smartphone: Cost = 350NRV=350 NRV = 500 − 20=20 = 480 Lower of cost and NRV = 350perunitValue=50×350 per unit Value = 50 × 350 = $17,500

Model Y Smartphone: Cost = 280NRV=280 NRV = 250 − 15=15 = 235 Lower of cost and NRV = 235perunitValue=30×235 per unit Value = 30 × 235 = $7,050

Phone Cases: Cost = 8NRV=8 NRV = 12 − 2=2 = 10 Lower of cost and NRV = 8perunitValue=200×8 per unit Value = 200 × 8 = $1,600

Marking:

  • Model X: Correct NRV calculation (480)andcorrectvaluation(480) and correct valuation (17,500): 2 marks
  • Model Y: Correct NRV calculation (235)andcorrectvaluation(235) and correct valuation (7,050): 2 marks
  • Phone Cases: Correct NRV calculation (10)andcorrectvaluation(10) and correct valuation (1,600): 2 marks
  • Award partial marks if NRV is correct but final value is wrong, or vice versa.

(c) Total closing inventory value (2 marks)

Total = 17,500+17,500 + 7,050 + 1,600=1,600 = 26,150

Marking:

  • Correct addition: 1 mark
  • Correct total ($26,150): 1 mark

(d) Benefits of computerised inventory management system (4 marks)

Benefits include:

  1. Real-time tracking: A computerised system can provide up-to-date information on inventory levels, helping the business avoid stock-outs or overstocking.
  2. Improved accuracy: Automated recording reduces the risk of human errors in counting and recording inventory movements.
  3. Better decision-making: The system can generate reports on sales trends, fast-moving items, and slow-moving items, enabling better purchasing and pricing decisions.
  4. Cost savings: By optimising inventory levels, the business can reduce storage costs, insurance costs, and losses from obsolescence.

Marking: 2 marks for each valid benefit clearly explained (maximum 4 marks).

(e) Inventory management and cash flow (2 marks)

Effective inventory management improves cash flow by ensuring that the business does not tie up excessive cash in slow-moving or excess inventory. By holding optimal inventory levels and turning over inventory quickly, the business can convert inventory into cash from sales more rapidly, making more cash available for other purposes such as paying suppliers or investing in growth.

Marking:

  • Link between inventory levels and cash tied up: 1 mark
  • Link between faster turnover and cash generation: 1 mark
