Answer Key and Marking Scheme
Version 4

Section A: Multiple Choice and Short Concepts [10 Marks]

Question 1
Answer: B) Prudence Concept
[1]
Note: Prudence ensures assets are not overstated.

Question 2
Answer: A) FIFO (First-In, First-Out)
[1]
Note: In rising prices, the older (cheaper) costs are sold first, leaving the newer (higher) costs in closing inventory.

Question 3
Answer:
Net Realizable Value is the estimated selling price in the ordinary course of business [1] less the estimated costs of completion and the estimated costs necessary to make the sale [1].
[2]

Question 4
Answer: (Any two of the following)

It smooths out price fluctuations, providing a more stable cost of sales figure. [1]
It is easier to administer than FIFO if there are many similar items, as specific batches do not need to be tracked. [1]
It is often perceived as a fairer representation of current costs compared to FIFO in volatile markets. [1]
[2]

Question 5
Answer: A) Consignor (Owner)
[1]
Note: Legal ownership remains with the consignor until sold.

Question 6
Answer: B) Understated by $500
[1]
Note: Cost of Sales = Opening Inv + Purchases - Closing Inv. If Opening Inv is overstated, Cost of Sales is overstated. If Cost of Sales is overstated, Gross Profit is understated.

Question 7
Answer: $51,000 [2] *Workings:* Opening Inventory:$ 12,000
Add: Purchases: $45,000 Add: Carriage Inwards:$ 2,000
Less: Closing Inventory: ( $8,000) Cost of Sales = 12,000 + 45,000 + 2,000 - 8,000 =$ 51,000.
[1 for correct formula/inclusion of carriage, 1 for correct answer]

Section B: Inventory Valuation Calculations (FIFO and AVCO) [18 Marks]

Question 8

(a) FIFO Method

(i) Closing Inventory Value
Total Units Available: 200 + 300 + 150 = 650 units
Total Units Sold: 250 + 300 = 550 units
Closing Inventory Units: 650 - 550 = 100 units

Under FIFO, the closing inventory consists of the most recent purchases.
The 100 units remaining are from the 18 Mar purchase.
Value = 100 units × $13.00 =$ 1,300.

[4]
[1 for identifying remaining units, 1 for identifying correct batch, 1 for calculation, 1 for final answer]
Answer: $1,300

(ii) Gross Profit (FIFO)
Sales Revenue:
250 units @ $25 =$ 6,250
300 units @ $25 =$ 7,500
Total Sales = $13,750

Cost of Sales (FIFO):
Opening Inventory: 200 @ $10 =$ 2,000
Purchase 1: 300 @ $12 =$ 3,600
Purchase 2: 150 @ $13 =$ 1,950
Total Goods Available for Sale = $7,550 Less Closing Inventory =$ 1,300
Cost of Sales = $7,550 -$ 1,300 = $6,250

Alternative COS Calculation (Flow of costs):
Sale 1 (250 units): 200 @ $10 + 50 @$ 12 = $2,000 +$ 600 = $2,600 Sale 2 (300 units): 250 @$ 12 + 50 @ $13 =$ 3,000 + $650 =$ 3,650
Total COS = $2,600 +$ 3,650 = $6,250

Gross Profit = Sales - COS
Gross Profit = $13,750 -$ 6,250 = $7,500

[3]
[1 for Sales, 1 for COS, 1 for Gross Profit]
Answer: $7,500

(b) AVCO Method

(i) Weighted Average Cost after 5 Mar Purchase
Opening: 200 units @ $10 =$ 2,000
Purchase: 300 units @ $12 =$ 3,600
Total: 500 units, Total Cost $5,600 Average Cost =$ 5,600 / 500 = $11.20 per unit

[1]
Answer: $11.20

(ii) Closing Inventory Value
Transaction Log:

10 Mar Sale (250 units):
Remaining: 250 units @ $11.20 =$ 2,800
**18 Mar Purchase (150 units @ $13):** New Inventory: 250 units @$ 11.20 ( $2,800) + 150 units @$ 13.00 ( $1,950) Total Units: 400 Total Cost:$ 4,750
New Average Cost: $4,750 / 400 =$ 11.875 per unit
25 Mar Sale (300 units):
Remaining: 100 units @ $11.875 Closing Inventory Value = 100 ×$ 11.875 = $1,187.50

[3]
[1 for first avg cost application, 1 for second avg cost calc, 1 for final value]
Answer: $1,187.50

(iii) Gross Profit (AVCO)
Sales Revenue: $13,750 (Same as above)

Cost of Sales:
Total Goods Available for Sale = $7,550 (Same as above) Less Closing Inventory =$ 1,187.50
Cost of Sales = $7,550 -$ 1,187.50 = $6,362.50

Alternative COS Calculation:
Sale 1: 250 @ $11.20 =$ 2,800
Sale 2: 300 @ $11.875 =$ 3,562.50
Total COS = $6,362.50

Gross Profit = $13,750 -$ 6,362.50 = $7,387.50

[3]
[1 for Sales, 1 for COS, 1 for Gross Profit]
Answer: $7,387.50

(c) Explanation of Difference
In a period of rising prices ( $10 ->$ 12 -> $13), FIFO assigns the older, lower costs to Cost of Sales, resulting in a lower COS and higher Gross Profit. AVCO averages the costs, resulting in a higher COS (relative to FIFO) and lower Gross Profit because the average cost is higher than the oldest costs used in FIFO.

Section C: Inventory Adjustments and Analysis [12 Marks]

Question 9

(a) Correct Closing Inventory Calculation

Initial Count: $45,000

Consignment Goods: Exclude. Ownership belongs to the customer.
Adjustment: ($2,000)
FOB Destination: Exclude. Ownership transfers on arrival (2 Jan). Goods were not owned on 31 Dec.
Adjustment: ($3,500)
Damaged Goods: Adjust to NRV.
NRV = Selling Price ( $800) - Repair Costs ($ 200) = $600. Current Value in Count:$ 1,500.
Adjustment: $600 -$ 1,500 = ($900)
FOB Shipping Point Sold Goods: Exclude. Ownership transferred to buyer on dispatch (31 Dec).
Adjustment: ($4,000)

Calculation:
$45,000 -$ 2,000 - $3,500 -$ 900 - $4,000 =$ 34,600

[6]
[1 for each correct adjustment direction and amount, 1 for final total]
Answer: $34,600

(b) Accounting Treatment for Damaged Goods
Inventory must be valued at the lower of cost and Net Realizable Value (NRV) [1]. This adheres to the Prudence Concept, ensuring assets are not overstated and potential losses are recognized immediately [1].

[2]

(c) Falling Prices Scenario

(i) Higher Cost of Sales: FIFO
[1]
Reasoning: In falling prices, the older inventory is more expensive. FIFO sells these first, leading to higher COS.

(ii) Higher Net Profit: AVCO
[1]
Reasoning: Since FIFO has higher COS, it has lower profit. AVCO smooths the cost, resulting in lower COS relative to FIFO in this specific scenario, hence higher profit.

(iii) Importance of Consistency
Consistency allows stakeholders to compare financial performance across different periods meaningfully [1]. If methods change frequently, it becomes difficult to distinguish whether changes in profit are due to operational performance or just accounting policy changes [1].
