(b) AVCO Method
(i) Cost of goods sold for March 2026 (5 marks)
| Date | Transaction | Units | Unit Cost ($) | Total Cost ($) | WAC per unit ($) |
|---|---|---|---|---|---|
| Mar 1 | Opening | 200 | 5.00 | 1,000 | 5.00 |
| Mar 5 | Purchase | 300 | 5.50 | 1,650 | (1,000+1,650)/500 = 5.30 |
| Mar 12 | Sale | (250) | |||
| Balance | 250 | 5.30 | 1,325 | 5.30 | |
| Mar 18 | Purchase | 400 | 6.00 | 2,400 | (1,325+2,400)/650 = 5.73 |
| Mar 25 | Sale | (350) | |||
| Balance | 300 | 5.73 | 1,719 | 5.73 | |
| Mar 30 | Purchase | 100 | 6.50 | 650 | (1,719+650)/400 = 5.92 |
COGS:
-
12 March: 250 × 1,325.00
-
25 March: 350 × 2,005.50
-
Total COGS = 2,005.50 = $3,330.50

-
Correct COGS for 12 March: 1 mark
-
Correct WAC after second purchase: 1 mark
-
Correct COGS for 25 March: 1 mark
-
Correct total COGS: 1 mark
(ii) Closing inventory as at 31 March 2026 (2 marks)
Closing inventory = 400 units × 2,368.00** (Or from running balance: 650 = $2,369.00; accept either due to rounding)
- Correct units remaining: 1 mark
- Correct valuation: 1 mark
(c) Gross profit comparison (3 marks)
Total sales revenue = (250 + 350) × 6,000
| Method | Revenue ($) | COGS ($) | Gross Profit ($) |
|---|---|---|---|
| FIFO | 6,000 | 3,250.00 | 2,750.00 |
| AVCO | 6,000 | 3,330.50 | 2,669.50 |
FIFO results in a higher gross profit (2,669.50).
Explanation: In a period of rising prices (unit cost increased from 6.50), FIFO charges the older, lower-cost inventory to cost of goods sold first. This results in a lower COGS and therefore a higher gross profit. AVCO smooths out the price increases by averaging all costs, resulting in a higher COGS and lower gross profit.
- Correct revenue calculation: 1 mark
- Correct gross profit comparison: 1 mark
- Clear explanation linking rising prices to profit difference: 1 mark
Question 2: Inventory Valuation and Errors (15 marks)
(a) Corrected closing inventory (5 marks)
Original closing inventory: $68,000
Adjustments:
Item 1: Lower of cost and NRV adjustments
- Item A: Cost 1,500 → Write down by $500
- Item B: Cost 4,000 → No adjustment (cost is lower)
- Item C: Cost 800 → Write down by $400
- Total write-down = 400 = $900
Item 2: Unrecorded purchase invoice
- Goods not included in closing inventory → No adjustment to closing inventory needed (goods were not counted)
Item 3: Goods sold but included in inventory
- Goods costing $2,800 were included in error → Remove from closing inventory
- Adjustment: −$2,800
Corrected closing inventory = 900 − 64,300**
- Correct write-down for Item A: 1 mark
- Correct treatment of Item B (no adjustment): 1 mark
- Correct write-down for Item C: 1 mark
- Correct treatment of Item 2 (no adjustment to inventory): 1 mark
- Correct treatment of Item 3 and correct total: 1 mark
(b) Corrected cost of goods sold (4 marks)
Cost of goods sold = Opening inventory + Net purchases + Carriage inwards − Closing inventory
Net purchases = 8,000 = $302,000
Adjustment for unrecorded purchase (Item 2):
- Purchases should include the $4,500 invoice (goods ordered, invoice dated 28 Dec 2025)
- Corrected net purchases = 4,500 = $306,500
Corrected COGS = 306,500 + 64,300 = $299,200
- Correct net purchases before adjustment: 1 mark
- Correct adjustment for unrecorded purchase: 1 mark
- Correct formula application: 1 mark
- Correct final COGS: 1 mark
(c) Corrected gross profit (3 marks)
Original gross profit = 480,000 − 291,000
Corrected COGS = 480,000 − 180,800**
Alternative method: Change in COGS = 291,000 = 189,000 − 180,800
- Correct original COGS or change in COGS: 1 mark
- Correct calculation approach: 1 mark
- Correct final gross profit: 1 mark
(d) Accounting concept explanation (3 marks)
The accounting concept is prudence (conservatism).
This concept requires that:
- Assets and income should not be overstated.
- Liabilities and expenses should not be understated.
- Losses should be recognised as soon as they are foreseen, while profits should only be recognised when they are realised.
Valuing inventory at the lower of cost and net realisable value ensures that inventory is not carried in the statement of financial position at an amount higher than what the business expects to recover from its sale. If NRV is lower than cost, the expected loss is recognised immediately by writing down the inventory value.
- Correct identification of prudence/conservatism: 1 mark
- Explanation of the concept (not overstating assets): 1 mark
- Application to inventory valuation: 1 mark
Question 3: Inventory Management and Analysis (15 marks)
(a) Ratio calculations
(i) Gross profit margin (4 marks)
FreshMart: Gross profit = 595,000 = 255,000 ÷ $850,000) × 100% = 30.0%
QuickShop: Gross profit = 465,000 = 155,000 ÷ $620,000) × 100% = 25.0%
- Correct gross profit for FreshMart: 1 mark
- Correct margin for FreshMart: 1 mark
- Correct gross profit for QuickShop: 1 mark
- Correct margin for QuickShop: 1 mark
(ii) Inventory turnover rate (4 marks)
FreshMart: Average inventory = (95,000) ÷ 2 = 595,000 ÷ $90,000 = 6.6 times
QuickShop: Average inventory = (65,000) ÷ 2 = 465,000 ÷ $60,000 = 7.8 times
- Correct average inventory for FreshMart: 1 mark
- Correct turnover for FreshMart: 1 mark
- Correct average inventory for QuickShop: 1 mark
- Correct turnover for QuickShop: 1 mark
(b) Comparison and commentary (4 marks)
| Ratio | FreshMart | QuickShop |
|---|---|---|
| Gross profit margin | 30.0% | 25.0% |
| Inventory turnover | 6.6 times | 7.8 times |
FreshMart has a higher gross profit margin (30.0% vs 25.0%), indicating it earns more gross profit per dollar of sales. This could be due to higher selling prices, lower purchase costs, or a different product mix.
However, QuickShop has a higher inventory turnover rate (7.8 times vs 6.6 times), meaning it sells and replaces its inventory more frequently. This suggests QuickShop is more efficient at managing its inventory levels, holding stock for a shorter period, which reduces storage costs and the risk of obsolescence.
The combination suggests FreshMart may be pursuing a higher-margin, lower-volume strategy, while QuickShop may be pursuing a lower-margin, higher-volume strategy. Both approaches can be valid depending on the business model.
- Correct comparison of gross profit margin with interpretation: 1 mark
- Correct comparison of inventory turnover with interpretation: 1 mark
- Insight linking the two ratios (strategy implication): 1 mark
- Overall coherent commentary: 1 mark
(c) Reasons for lower inventory turnover (3 marks)
Possible reasons (any two, 1.5 marks each):
-
Product mix differences: QuickShop may stock more slow-moving or specialty items that take longer to sell, while FreshMart focuses on fast-moving everyday groceries.
-
Purchasing strategy: QuickShop may buy in larger bulk quantities to obtain volume discounts, resulting in higher average inventory levels and a lower turnover rate.
-
Pricing strategy: QuickShop's lower gross profit margin (25.0%) may indicate it charges lower prices to attract customers, but this has not translated into faster inventory movement, possibly due to weaker demand or less effective marketing.
-
Store location or customer base: QuickShop may be located in an area with lower customer traffic or serve a smaller customer base, leading to slower sales.
-
Inventory management practices: QuickShop may have less sophisticated inventory management systems, leading to overstocking or holding obsolete items.
- Two valid, distinct reasons: 1.5 marks each
- Reasons linked to the context or ratios: bonus consideration within marks
Question 4: Inventory Decision-Making Scenario (15 marks)
(a) Cost of flour issued to production
(i) FIFO method (3 marks)
| Date | Issued (kg) | Cost allocation | Cost ($) |
|---|---|---|---|
| Jan 15 | 1,500 | 1,000 kg @ 2.40 | 2,000 + 1,200 = 3,200 |
| Jan 29 | 2,000 | 1,500 kg @ 2.80 | 3,600 + 1,400 = 5,000 |
| Total | 8,200 |
- Correct allocation for 15 Jan: 1 mark
- Correct allocation for 29 Jan: 1 mark
- Correct total: 1 mark
(ii) AVCO method (4 marks)
| Date | Transaction | Units (kg) | Cost/kg ($) | Total Cost ($) | WAC ($) |
|---|---|---|---|---|---|
| Jan 1 | Opening | 1,000 | 2.00 | 2,000 | 2.00 |
| Jan 8 | Purchase | 2,000 | 2.40 | 4,800 | (2,000+4,800)/3,000 = 2.27 |
| Jan 15 | Issue | (1,500) | |||
| Balance | 1,500 | 2.27 | 3,405 | 2.27 | |
| Jan 22 | Purchase | 1,500 | 2.80 | 4,200 | (3,405+4,200)/3,000 = 2.54 |
| Jan 29 | Issue | (2,000) | |||
| Balance | 1,000 | 2.54 | 2,540 | 2.54 |
Cost of issues:
-
15 Jan: 1,500 × 3,405.00
-
29 Jan: 2,000 × 5,080.00
-
Total = $8,485.00
-
Correct WAC after first purchase: 1 mark
-
Correct cost for 15 Jan issue: 1 mark
-
Correct WAC after second purchase: 1 mark
-
Correct cost for 29 Jan issue and total: 1 mark
(b) Effect on reported profit (3 marks)
Under FIFO, the cost of flour issued is 8,485.
If BakeWell switches from FIFO to AVCO, the cost of raw materials issued to production would increase by 8,485 − $8,200). This means the cost of production would be higher, leading to a higher cost of goods sold and therefore a lower gross profit and lower net profit for January 2026.
In a period of rising prices (flour cost increased from 2.80 per kg), AVCO produces a higher COGS than FIFO because it averages the higher recent purchase costs into the cost of issues, whereas FIFO uses the older, lower costs first.
- Correct identification of cost difference: 1 mark
- Correct direction of profit effect (lower profit under AVCO): 1 mark
- Explanation linking rising prices to the effect: 1 mark
(c) Recommendation report (5 marks)
Sample answer (award marks for quality and structure):
To: Management of BakeWell Pte Ltd From: Management Accountant Date: [Date] Subject: Recommendation on Inventory Valuation Method
Recommendation: BakeWell should switch to the Weighted Average Cost (AVCO) method for valuing its flour inventory.
Accounting Reasons:
-
Smoother profit reporting: AVCO smooths out the effects of price fluctuations by averaging the cost of inventory over time. In a period of volatile flour prices, AVCO provides a more stable and representative cost of goods sold, avoiding large swings in reported profit from one period to the next. This makes financial statements more useful for trend analysis and decision-making.
-
Better matching of costs to revenue: AVCO assigns an average cost to each unit issued to production, which better reflects the overall cost of resources consumed during the period. This aligns with the matching principle, as the cost of flour used in producing goods sold is more fairly stated.
Non-Accounting Factor:
Management should also consider the administrative complexity of switching methods. AVCO requires recalculation of the weighted average cost after every purchase, which may require more sophisticated inventory management software or additional staff training. The company should evaluate whether its current systems can handle this change efficiently and whether the benefits of switching outweigh the implementation costs.
Marking scheme (5 marks):
- Clear recommendation stated: 1 mark
- First accounting reason, well-explained: 1.5 marks
- Second accounting reason, well-explained: 1.5 marks
- One relevant non-accounting factor: 1 mark
