IAS 2 Inventories | StandardsHub

Conceptual Framework Linkage

Why inventory measurement is a matching exercise

Inventory is a textbook Framework asset: a present economic resource controlled by the entity, from a past purchase or production event, with the potential to produce economic benefits through sale. IAS 2 exists to ensure the cost of that resource is matched against the revenue it generates in the SAME period.

HOW INVENTORY MAPS TO THE FRAMEWORK'S ELEMENTS

Control – legal ownership is common, but not required; control (e.g. via consignment terms) is the real test Past event – purchase or production of the goods Future economic benefit – cash inflows from eventual sale in the ordinary course of business

The lower-of-cost-and-NRV rule (Section 6) is a direct application of the Framework's prudence concept operating within neutrality – assets are not carried above the amount expected to be recovered through sale.

Measurement principles applied by IAS 2

IAS 2 uses historical cost as its foundation, but caps it at net realisable value – a hybrid approach the Framework explicitly permits when historical cost alone would overstate the asset.

Framework basisUsed by IAS 2 for…

Historical costInitial measurement – purchase cost, conversion cost, other costs to bring inventory to present location/condition

Net realisable value (a current-value-adjacent basis)Ceiling applied at each reporting date – write-down if NRV falls below cost

Fair value less costs to sell (point of harvest)Agricultural produce transferred in from IAS 41 – becomes IAS 2's "cost"

Qualitative characteristics in action: the lower-of-cost-and-NRV test balances relevance (reflecting a genuine decline in recoverable value) against faithful representation (never allowing inventory to be carried above what it can realistically generate).

Scope & Applicability

What IAS 2 covers

IAS 2 applies to all inventories, EXCEPT those specifically scoped out below. 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 materials/supplies to be consumed in production or rendering of services.

CLASSIC CLASSES OF INVENTORY

Merchandise purchased for resale; land and other property held for resale; finished goods produced; work in progress; raw materials and supplies awaiting use in the production process.

SCOPE EXCLUSIONS – GOVERNED BY OTHER STANDARDS

Financial instruments → IFRS 9 Biological assets and agricultural produce at the point of harvest → IAS 41 (fair value less costs to sell governs UP TO harvest; IAS 2 takes over AFTER) Work in progress arising under construction contracts, including directly related service contracts → IFRS 15 Measurement of inventories held by commodity broker-traders, measured at FV less costs to sell → excluded from IAS 2's measurement rules (only its disclosure rules apply)

Key definitions you must know

Net realisable value (NRV)

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.

Fair value

The price that would be received to sell an asset in an orderly transaction between market participants at the measurement date – a MARKET-based measure, distinct from NRV which is entity-specific.

Cost of inventories

All costs of purchase, costs of conversion, and other costs incurred in bringing inventories to their present location and condition.

Commodity broker-traders

Those who buy or sell commodities for others or on their own account, and whose inventories are principally acquired with the purpose of selling in the near future and generating a profit from fluctuations in price or broker-traders' margin.

Recognition Criteria

When inventory is recognised – and derecognised

Inventory is recognised as an asset when the entity has CONTROL over the goods (usually, but not always, coinciding with legal title/risk and reward transfer), and it is probable future economic benefits will flow to the entity, with cost reliably measurable.

Common recognition trigger points

Goods purchased "FOB shipping point" are recognised by the buyer from the shipping date; "FOB destination" goods are recognised only on arrival – control, not just physical possession, drives the answer.

Derecognition

Inventory is derecognised (expensed as cost of sales) in the SAME period the related revenue is recognised – the direct matching principle central to IAS 2's design.

Consignment inventory remains on the CONSIGNOR's books (not the holder's) until sold to a third party, because control has not transferred to the party holding the physical goods – a frequently tested scope/control judgement.

Cost of Inventories – What's Included and Excluded

The three cost components

Cost = Costs of purchase + Costs of conversion + Other costs to bring to present location and condition

COSTS OF PURCHASE – INCLUDE

Purchase price, import duties and other non-recoverable taxes Transport, handling, and other costs directly attributable to acquisition LESS: trade discounts, rebates, and similar items

COSTS OF CONVERSION – INCLUDE

Costs directly related to units of production (direct labour, direct materials) Systematic allocation of FIXED production overheads, based on NORMAL capacity Systematic allocation of VARIABLE production overheads, based on ACTUAL usage

Costs EXCLUDED from inventory – always expensed

Abnormal amounts of wasted materials, labour, or other production costs Storage costs, UNLESS necessary in the production process before a further production stage Administrative overheads that do not contribute to bringing inventories to present location/condition Selling costs Foreign exchange differences arising directly on the recent acquisition of inventories invoiced in a foreign currency (general rule – not capitalised, per IAS 21)

Example 1: Fixed overhead allocation using normal capacity

A factory has normal production capacity of 10,000 units per month. Fixed production overheads are $50,000 per month. In a particular month, actual production is only 8,000 units due to a temporary equipment issue.

Fixed overhead per unit = $50,000 ÷ 10,000 (NORMAL capacity, not actual) = $5/unit
Allocated to the 8,000 units produced = 8,000 × $5 = $40,000 → capitalised in inventory
Unallocated overhead = $50,000 − $40,000 = $10,000 → expensed immediately as a period cost (reflects idle capacity, not further capitalised)

Cost Formulas – FIFO, Weighted Average & Specific Identification

The three permitted approaches

Specific identification – MANDATORY for items that are not ordinarily interchangeable, and goods/services produced and segregated for specific projects FIFO – assumes items purchased/produced first are sold first; closing inventory reflects most RECENT costs Weighted average cost – cost of each item determined from the weighted average of similar items at the beginning of the period and those purchased/produced during the period

LIFO (last-in, first-out) is explicitly PROHIBITED under IFRS – one of the clearest, most heavily examined IFRS vs US GAAP differences (see Section 11).

Worked example – FIFO vs weighted average

Example 2: Comparing FIFO and weighted average

Opening inventory: 100 units @ $10 = $1,000. Purchases: 200 units @ $12 = $2,400. Sales during the period: 250 units. Total units available: 300; closing inventory: 50 units.

FIFO: closing inventory = 50 units from the LAST purchase batch @ $12 = $600
Weighted average: average cost = (1,000 + 2,400) ÷ 300 = $11.33/unit; closing inventory = 50 × $11.33 = $567 (rounded)
The SAME cost formula must be applied to all inventories of similar nature and use to the entity; a different formula may be justified for inventories with a different nature or use.

The chosen formula is an accounting POLICY (IAS 8) and must be disclosed and applied consistently across periods, subject to the "similar nature and use" test permitting a different formula for genuinely different categories.

Net Realisable Value & Write-Downs

Lower of cost and NRV – applied item by item

GENERAL RULE

NRV = Estimated selling price − Estimated costs of completion − Estimated costs necessary to make the sale

The comparison of cost and NRV is made on an ITEM-BY-ITEM basis (or by group of similar/related items) – NOT by broad classification of all inventories, and NOT based on total inventory value.

Materials and supplies held for use in production are NOT written down below cost if the finished products they'll be incorporated into are still expected to sell at or above cost – a specific carve-out that is a common exam trap.

Worked example – write-down and reversal

Example 3: NRV write-down, then partial reversal

Product X: cost $80/unit, 500 units. At year-end 20X1, estimated selling price has fallen to $70/unit with $5/unit selling costs (NRV = $65). At year-end 20X2, selling prices recover; NRV rises back to $78/unit.

20X1: Lower of cost ($80) and NRV ($65) = $65/unit. Write-down = (80 − 65) × 500 = $7,500 expense, inventory carried at $65 × 500 = $32,500.
20X2: New NRV ($78) is still below original cost ($80), so inventory is remeasured at the LOWER of original cost and new NRV = $78/unit. Reversal = (78 − 65) × 500 = $6,500 reversal (reduces cost of sales), capped at the amount of the original write-down.

Reversals are permitted (unlike PPE impairments in some cases) but are strictly capped at the original write-down amount – inventory can never be written back up above original cost.

Recognition as an Expense

The matching mechanics and journal entries

When inventories are sold, their carrying amount is recognised as an expense (cost of sales) in the period the related revenue is recognised. Write-downs to NRV, and all inventory losses, are recognised as an expense in the period the write-down or loss occurs.

JOURNAL ENTRIES – SALE OF INVENTORY

Cost of sales (cost of goods sold)

SOPL

Inventory

SOFP

JOURNAL ENTRY – WRITE-DOWN TO NRV

Cost of sales / inventory write-down expense

SOPL

Inventory (or allowance for NRV write-down)

SOFP

Some amounts, such as materials/components used in constructing a self-built asset, allocate inventory cost to the COST of another asset instead – e.g. capitalised into PPE under IAS 16 rather than expensed.

Techniques for Measuring Cost

Standard cost and retail method – practical approximations

Standard cost method – takes into account normal levels of materials, labour, efficiency, and capacity utilisation, regularly reviewed and revised if conditions change; used ONLY if results approximate actual cost Retail method – used in the retail industry for large numbers of rapidly changing items with similar margins where it's impracticable to use other costing methods; inventory value is reduced by an appropriate gross margin percentage from its sales value

Both methods are convenience techniques for MEASURING cost, not separate cost FORMULAS – they must still produce a result reasonably approximating actual historical cost.

Worked example – retail method

Example 4: Retail method calculation

A retailer's inventory has a retail selling price of $120,000. The standard gross margin across the relevant department is 35%.

Estimated cost = Retail value × (1 − gross margin %) = 120,000 × (1 − 0.35) = $78,000

This is a practical expedient commonly seen in retail/supermarket exam scenarios, and is tested alongside the general lower-of-cost-and-NRV rule.

Disclosure Requirements

Required disclosures

GENERAL DISCLOSURES

The accounting policies adopted, including the cost formula(s) used Total carrying amount of inventories, and the carrying amount in classifications appropriate to the entity (e.g. merchandise, raw materials, WIP, finished goods) Carrying amount of inventories carried at fair value less costs to sell Amount of inventories recognised as an expense during the period (cost of sales)

WRITE-DOWN & RELATED DISCLOSURES

Amount of any write-down of inventories recognised as an expense in the period Amount of any reversal of a write-down, and the circumstances/events that led to the reversal Carrying amount of inventories pledged as security for liabilities

Critical Judgments & Estimates

Where management judgement matters most

SIGNIFICANT ESTIMATES

Estimated selling price, costs of completion, and costs to sell used in the NRV calculation "Normal capacity" used to allocate fixed production overheads (a range is often used, averaged over several periods to smooth abnormal fluctuations) Obsolescence and slow-moving provisions for inventory unlikely to sell at expected prices

SIGNIFICANT JUDGEMENTS

Whether the entity has "control" over goods in transit or on consignment, driving the recognition timing Whether costs of conversion overhead allocations reflect genuinely "abnormal" wastage requiring immediate expensing Whether inventories of a genuinely different nature/use justify a different cost formula

Determining "normal capacity" is one of the most subjective areas of IAS 2 – using ACTUAL production instead in a low-output period would understate the abnormal-cost expense and overstate inventory, a common examiner trap.

IFRS vs US GAAP – Key Differences

Comparison – IAS 2 vs US GAAP (ASC 330)

FeatureIFRS (IAS 2)US GAAP

LIFOPROHIBITEDPermitted, and commonly used (tax advantages in rising-price environments)

Write-down ceilingLower of cost and NRVLower of cost and market (for LIFO/retail method users) or lower of cost and NRV (for others, since ASU 2015-11)

Reversal of write-downsPermitted, capped at original write-downPROHIBITED – once written down, the new value becomes the new cost basis, never reversed

Item-level vs aggregate NRV testingItem-by-item (or similar group)Generally consistent with item-level, though practice varies by method used

The LIFO prohibition and the write-down reversal prohibition are the two most heavily tested IFRS/US GAAP differences for this standard – LIFO's tax-driven popularity in the US creates a structural, non-converging gap between the two frameworks.

Related Standards – Cross-Reference Map

How IAS 2 connects across the IFRS body of literature

StandardNature of the connection

IAS 41Agricultural produce is measured at fair value less costs to sell UP TO the point of harvest under IAS 41; that amount becomes the deemed "cost" IAS 2 uses thereafter

IFRS 15Determines WHEN revenue (and therefore matching cost of sales) is recognised; also governs work in progress under long-term contracts, which is scoped OUT of IAS 2

IAS 21Governs foreign exchange differences on inventory purchases invoiced in foreign currency – generally NOT capitalised into inventory cost

IAS 23Borrowing costs directly attributable to inventories that take a substantial period to get ready for sale (qualifying assets, e.g. maturing whisky/wine) are capitalised into inventory cost

IAS 16Inventory consumed in constructing a self-built item of PPE is transferred out of inventory and capitalised as part of that asset's cost instead of being expensed

IFRS 9Financial instruments (e.g. commodity derivatives used to hedge inventory price risk) are excluded from IAS 2 and follow IFRS 9's own rules

IAS 1Determines presentation of inventory within current assets on the SOFP, and cost of sales presentation choices (by nature vs by function)

IAS 8Governs treatment of a change in cost formula, which is treated as a change in accounting policy, applied retrospectively

Quick-Reference Glossary

Costs of conversion

Costs directly related to units of production, plus a systematic allocation of fixed and variable production overheads.

Normal capacity

The production expected to be achieved on average over a number of periods/seasons under normal circumstances, taking into account planned maintenance downtime.

By-products

Products of relatively minor value arising alongside a main product from a joint production process – often measured at NRV, deducted from the main product's cost.

Joint products

Products produced simultaneously from the same raw material/process, each with significant relative sales value – costs allocated between them on a rational, consistent basis (e.g. relative sales value).

Retail method

A cost measurement technique deducting an appropriate gross margin percentage from retail sales value to approximate cost, used in the retail industry.

Standard cost

A predetermined cost based on normal levels of materials, labour, efficiency, and capacity utilisation, regularly reviewed and revised.
