Inventories: Valuation, Accounting & Control for CA Foundation Students

Inventories represent a significant asset for most businesses, impacting both the Balance Sheet and the Income Statement. Proper accounting and valuation are crucial for presenting a true and fair view. This guide covers AS-2 (Accounting Standard 2) and relevant aspects of Ind-AS 2 for CA Foundation students, focusing on cost formulas, Net Realizable Value (NRV), and practical application.

Quick Answer for Featured Snippets:
Inventories are assets held for sale in the ordinary course of business, in the process of production for such sale, or in the form of raw materials or supplies to be consumed in the production process or in the rendering of services. They are valued at the lower of Cost and Net Realizable Value (NRV).

What are Inventories? Definition & Scope

As per AS-2 (Revised 2016) and Ind-AS 2:
Inventories are assets held for sale in the ordinary course of business; or in the process of production for such sale; or in the form of raw materials or consumables to be consumed in the production process or in the rendering of services.

Main Categories Included:

• Goods purchased for resale (e.g., merchandise in a retail store).
• Finished goods produced by the entity (e.g., cars manufactured by an auto company).
• Work-in-progress (WIP) goods in the production process.
• Raw materials and consumable stores (e.g., components for manufacturing, fuel for factory).
• Loose tools and spare parts if they meet the definition of inventory (i.e., consumed in production or held for resale).

Scope Exclusions:

• Work-in-progress arising under construction contracts (covered by AS-7/Ind-AS 115).
• Financial instruments (covered by Ind-AS 32, 109, etc.).
• Produce of agriculture and forest products, mineral oils, etc., after they are harvested/extracted (measured at NRV less costs to sell as per AS-32/Ind-AS 41). However, they are covered before harvest/extraction.

Measurement of Inventories: Cost & NRV

Inventories shall be measured at the lower of Cost and Net Realizable Value (NRV).

Cost of Inventories

• Includes all costs of purchase, costs of conversion, and other costs incurred in bringing the inventories to their present location and condition.
• Costs of Purchase: Purchase price, import duties, other taxes (non-refundable), transport, handling, and other directly attributable expenditure. Trade discounts, rebates, and other similar items are deducted.

Costs of Conversion:

• Directly related to the production of specific units (e.g., direct labour).
• Overheads (both variable and fixed) that are allocated on a systematic basis. Fixed overheads are allocated based on normal capacity utilization. Variable overheads are allocated based on actual usage.

Other Costs:

• Costs incurred in bringing the inventory to its present location and condition (e.g., storage costs, design costs for specific products).
• Exclusions: Storage costs of finished goods (unless necessary for production), administrative overheads, selling and distribution costs (these are expensed in the period incurred).

Net Realizable Value (NRV):

• NRV is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale (e.g., selling commission, transport to customer).
• NRV is determined on an item-by-item basis. If necessary, grouping is done for similar items.

Cost Formulas for Inventory Valuation

When inventories have been acquired or produced, and some items are indistinguishable from others, the cost of each item is determined using one of the following formulas:

Key Insight: The choice of formula should be consistent. If a change is made, it's a change in accounting policy requiring justification and retrospective application (Ind-AS 8).

First-In, First-Out (FIFO) Method

Assumes that the items of inventory that were purchased or produced first are sold first. Therefore, the cost of the earliest purchases is charged to Cost of Goods Sold (COGS), and the cost of the most recent purchases remains in inventory.

Formula:

• Cost of Goods Sold = Cost of Oldest Inventory Items
• Ending Inventory = Cost of Most Recent Inventory Items

Pros: Reflects physical flow for many businesses; ending inventory valued closer to current replacement cost.
Cons: COGS may not reflect current costs; can lead to 'inventory profits' during inflation.

Weighted Average Cost (WAC) Method

The cost of each item is determined from the weighted average of the cost of similar items at the beginning of the period and the cost of similar items purchased or produced during the period. The average cost may be calculated on a periodic basis, or as each additional shipment is received, depending on the circumstances.

Formula:

• Periodic WAC: $$\text{Periodic WAC} = \frac{\text{Total Cost of Goods Available for Sale}}{\text{Total Units Available for Sale}}$$
• Moving WAC (after each purchase): $$\text{Moving WAC} = \frac{\text{Cost of Inventory on Hand} + \text{Cost of New Purchase}}{\text{Units on Hand} + \text{Units of New Purchase}}$$

Pros: Smooths out price fluctuations; simpler than FIFO for large volumes.
Cons: COGS and ending inventory may not reflect actual physical flow or current costs.

Note: Specific Identification Method: Used for inventories that are not ordinarily interchangeable and are segregated for specific projects (e.g., custom-built equipment, high-value unique items). Cost is identified with specific items. This is not a formula but a direct costing approach.

Inventory Control & Verification

Effective inventory management is vital. Key aspects include:

• Inventory Control Systems: Techniques like EOQ (Economic Order Quantity), ABC Analysis, Just-In-Time (JIT) help manage inventory levels, reduce holding costs, and prevent stock-outs or overstocking.
• Physical Verification: Regular counting of physical stock (periodic or perpetual inventory system) to compare with records. Discrepancies (shortages/excesses) need investigation and adjustment.
• Documentation: Maintaining proper records like Goods Received Notes (GRNs), Goods Issue Notes (GINs), Bin Cards, Stores Ledger, etc.

Accounting Entries for Inventories

Inventories are typically accounted for using a Periodic Inventory System or a Perpetual Inventory System. The treatment differs:

Periodic Inventory System

• Purchases are debited to Purchases Account.
• Sales are recorded at selling price.
• At year-end, physical stock is counted.
• Adjustment Entry:
  Dr. Closing Inventory A/c
  Cr. Purchases A/c (to close Purchases)
  Cr. Profit & Loss Adjustment A/c (for difference if any, e.g., shortage)

Perpetual Inventory System

• Purchases are debited to Inventory Account.
• Sales are recorded at cost price (COGS).
• Inventory Account shows continuous balance.
• Physical verification is for control and detecting discrepancies.
• Entry for Shortage:
  Dr. Inventory Shortage / Loss A/c
  Cr. Inventory A/c

CA Foundation Exam Note: CA Foundation primarily uses the Periodic system for numericals. The key is calculating COGS = Opening Inventory + Purchases – Closing Inventory.

Short Form Questions (Conceptual & Numerical)

Q1. Define 'Inventories' as per AS-2. What are the main categories included?

Model Answer:
Inventories are assets held for sale in the ordinary course of business; or in the process of production for such sale; or in the form of raw materials or consumables to be consumed in the production process or in the rendering of services.

Main categories: Goods for resale, Finished goods, Work-in-progress, Raw materials, Consumable stores, Loose tools (if meeting definition).

Q2. What is the fundamental principle for valuing inventories?

Model Answer:
Inventories shall be measured at the lower of Cost and Net Realizable Value (NRV).

Q3. Distinguish between FIFO and Weighted Average Cost method.

Model Answer:
FIFO assumes oldest items are sold first, so COGS reflects older costs and ending inventory reflects newer costs. Weighted Average Cost calculates an average cost for all similar items and uses this average for both COGS and ending inventory, smoothing out price fluctuations.

Q4. Calculate the Cost of Goods Sold (COGS) using FIFO method. Opening Inventory: 100 units @ ₹100. Purchases: 200 units @ ₹110, 300 units @ ₹120. Units Sold: 450 units.

Model Answer:
Units sold: 450
From Opening Inv: 100 units @ ₹100 = ₹10,000
From 1st Purchase: 200 units @ ₹110 = ₹22,000
Remaining needed: 450 - 100 - 200 = 150 units
From 2nd Purchase: 150 units @ ₹120 = ₹18,000

Total COGS (FIFO) = ₹10,000 + ₹22,000 + ₹18,000 = ₹50,000

Q5. What is Net Realizable Value (NRV)? When is it applied?

Model Answer:
NRV is the estimated selling price in the ordinary course of business less estimated costs of completion and costs of making the sale. It is applied when NRV is lower than the cost of inventory, requiring the inventory to be written down to its NRV.

Q6. Briefly explain the treatment of inventory shortages in a periodic system.

Model Answer:
In a periodic system, shortages are typically discovered during the year-end physical verification. The difference between the book balance (calculated via Purchases A/c) and the physical count is adjusted. If the physical count is less than expected, the difference is usually debited to 'Inventory Shortage' or 'Loss on Inventory' account and credited to Purchases or Inventory account.

Case Studies (Comprehensive Scenarios with Full Solutions)

Case Study 1: Inventory Valuation using FIFO and Weighted Average (Periodic System)

The following transactions occurred in the stores ledger of M/s. Alpha Traders during April 2024:
April 1: Opening Balance: 100 units @ ₹100 per unit.
April 5: Purchased 200 units @ ₹110 per unit.
April 10: Sold 150 units.
April 15: Purchased 300 units @ ₹120 per unit.
April 20: Sold 250 units.
April 25: Purchased 150 units @ ₹130 per unit.
April 30: Sold 200 units.

Assume a periodic inventory system is used. Calculate the value of closing inventory and Cost of Goods Sold (COGS) as at April 30, 2024, using:
(a) FIFO method
(b) Weighted Average Cost method.

Model Solution:

Stores Ledger Extract (Periodic System):

Total Units: Opening (100) + Purchase (200+300+150) = 750 units
Total Amount Available: 10,000 + 22,000 + 36,000 + 19,500 = ₹87,500
Total Units Issued (Sold): 150 + 250 + 200 = 600 units
Closing Inventory Units: 750 - 600 = 150 units

(a) FIFO Method:

• COGS:

  • From Opening Bal: 100 units @ ₹100 = ₹10,000

  • From Apr 5 Purchase: 50 units @ ₹110 = ₹5,500

  • Total COGS = ₹15,500 (for first 150 units sold)

  • From Apr 15 Purchase: 150 units @ ₹120 = ₹18,000

  • From Apr 25 Purchase: 100 units @ ₹130 = ₹13,000

  • Total COGS = ₹31,000 (for next 250 units sold)

  • From Apr 25 Purchase: 150 units @ ₹130 = ₹19,500

  • From Apr 15 Purchase: 50 units @ ₹120 = ₹6,000

  • Total COGS = ₹25,500 (for last 200 units sold)

  Total COGS (FIFO) = ₹15,500 + ₹31,000 + ₹25,500 = ₹72,000

• Closing Inventory (150 units):

  • From Apr 25 Purchase: 150 units @ ₹130 = ₹19,500

(b) Weighted Average Cost Method (Periodic):

• Total Cost of Goods Available for Sale = ₹87,500

• Total Units Available for Sale = 750 units

• Weighted Average Rate = ₹87,500 / 750 = ₹116.67 per unit (approx)

• COGS: 600 units × ₹116.67 = ₹70,000 (approx)

• Closing Inventory: 150 units × ₹116.67 = ₹17,500 (approx)

(Note: The stores ledger extract above uses a simplified 'balance' column. In a real periodic system, you'd calculate COGS based on the issue rates derived from FIFO/WAC at the time of sale, and the final balance would be the remaining units valued at the latest rates/average.)

Case Study 2: Inventory Valuation at Lower of Cost and NRV

From the records of a company, the following information is available for inventory items at the year-end:

Requirements:
(a) Calculate the Cost and NRV for each inventory item.
(b) Determine the value of inventory for each item based on the lower of Cost and NRV.
(c) Calculate the total value of inventory to be presented in the Balance Sheet.
(d) Calculate the amount of write-down, if any, required.

Model Solution:

1. Calculations:

2. Valuation at Lower of Cost and NRV:

(Correction in calculation based on typical interpretation: For WIP, 'cost to complete' is subtracted from NRV to get the NRV of WIP. The cost per unit of WIP already includes costs incurred to date. Let's re-evaluate NRV for C assuming cost to complete is additional cost)

Revised Calculation for WIP C:
NRV per Unit = Est. Selling Price - Est. Cost to Sell - Est. Cost to Complete
NRV per Unit = 160 - 15 - 10 = ₹135
Total NRV = 200 units * ₹135 = ₹27,000

Revised Valuation at Lower of Cost and NRV:

(Self-correction: The initial interpretation of NRV for WIP might have been incorrect. Let's assume the question implies 'cost to complete' is an additional cost to bring WIP to finished state before selling. If 'cost to complete' is already part of the ₹120 cost per unit, then NRV calculation differs. Assuming 'cost to complete' is additional cost.)

Let's re-evaluate NRV for C assuming cost to complete is additional cost:
NRV per Unit = Est. Selling Price - Est. Cost to Sell - Est. Cost to Complete
NRV per Unit = 160 - 15 - 10 = ₹135
Total NRV = 200 units * ₹135 = ₹27,000

Valuation at Lower of Cost and NRV:

(Final check: The provided example answer suggests a write-down for A. Let's re-read the definition of NRV carefully.)

NRV Definition: Estimated selling price less estimated costs of completion and estimated costs necessary to make the sale.

Item A: Cost = 80. Selling Price = 95. Cost to Sell = 10. NRV = 95 - 10 = 85. Lower of Cost (80) and NRV (85) is 80. No write-down.

Item B: Cost = 150. Selling Price = 180. Cost to Sell = 20. NRV = 180 - 20 = 160. Lower of Cost (150) and NRV (160) is 150. No write-down.

Item C: Cost = 120. Selling Price = 160. Cost to Sell = 15. Cost to Complete = 10. NRV = 160 - 15 - 10 = 135. Lower of Cost (120) and NRV (135) is 120. No write-down.

(It seems my initial interpretation of the example answer was incorrect, or the example itself had a typo. Based strictly on AS-2, no write-down is needed here. However, if the question intended a write-down, the NRV calculation for A would need to be lower than 80. Let's assume the example answer's logic for A was correct and try to reverse-engineer: If NRV was lower than 80, say 75, then write-down would be 5. Let's proceed with the standard calculation as per AS-2.)

Corrected Calculation based on AS-2:

(a) & (b) Calculations & Lower Value: As above.

(c) Total Value of Inventory: ₹40,000 + ₹1,50,000 + ₹24,000 = ₹2,14,000

(d) Total Write-down: ₹0

(If the example answer intended a write-down for A, perhaps the selling price was intended to be lower, e.g., 85, making NRV 75, leading to a write-down of 5 per unit.)
