What this instrument changes, mechanically

This Standard sets the accounting rules for measuring, recognising and disclosing inventories in general-purpose financial statements. The basic mechanical rule is: measure inventories at the lower of cost and net realisable value (NRV) (paragraph 9). When inventories are sold, their carrying amount is recognised as an expense in the same period as the related revenue (paragraph 34).

Who and what it covers

Applies to all inventories except financial instruments and biological assets at harvest (paragraph 2(b) and 2(c)) and subject to industry carve-outs for producers of agricultural/forest products, minerals and commodity broker-traders that follow established industry measurement practices (paragraphs 3–5). Agricultural produce harvested from biological assets is measured at fair value less costs to sell at the point of harvest and that amount is treated as the cost for applying this Standard (paragraph 20).

Key mechanical rules and choices required of reporting entities

Components of cost: inventories’ cost comprises costs of purchase, conversion and other costs necessary to bring inventories to their present location and condition (paragraph 10). Specific breakdowns and examples are in paragraphs 11–18 (purchase costs, conversion costs, excluded costs, borrowing costs).
Cost assignment methods: specific identification for non‑interchangeable items (paragraphs 23–24); otherwise FIFO or weighted average must be used and applied consistently across inventories of a similar nature and use (paragraphs 25–27).

What it does

AASB 102 prescribes how entities applying Australian Accounting Standards measure, recognise and disclose inventories. The Standard establishes the fundamental measurement rule that inventories are measured at the lower of cost and net realisable value (para 9). For not-for-profit entities the Standard departs from the lower‑of‑cost‑and‑replacement‑cost approach that previously applied to inventories held for distribution: such inventories are measured at cost, adjusted when applicable for any loss of service potential (Aus9.1). The Standard also contains a targeted initial-measurement rule for certain not‑for‑profit situations where inventories are acquired for consideration significantly less than fair value: those inventories may be initially measured at current replacement cost (Aus10.1-Aus10.2), with AASB 1058 governing related income recognition.

Scope exclusions and alternatives are provided. Financial instruments, and biological assets and agricultural produce at harvest are outside the Standard (para 2(b)-(c)). Producers of agricultural/forest products, minerals and commodity broker‑traders may measure inventories under well‑established industry practice or at fair value less costs to sell; where those practices are used the inventories are excluded from this Standard’s measurement requirements, not necessarily from other requirements (paras 3-5, 4). Agricultural produce harvested from biological assets uses AASB 141 fair value less costs to sell as the cost basis on initial recognition (para 20).

The Standard defines which cost components to capitalise (costs of purchase, conversion and other costs that bring inventories to their present location and condition) and lists items excluded from cost (abnormal waste, storage costs except when necessary in the production process, administrative overheads not contributing to bringing inventories to condition, selling costs) (paras 10-18). Cost assignment methods are prescribed: specific identification for non‑interchangeable items, FIFO or weighted average for other inventories, with consistent use across inventories of similar nature and use (paras 23-27). Measurement techniques such as standard costs and the retail method are permitted if they approximate cost (paras 21-22).

Who pays: reporting entities (for‑profit and not‑for‑profit) bear the compliance and measurement costs because they must implement measurement algorithms, keep supporting records and make estimates required by the Standard (see paragraphs 9, 10, 11–18, 23–27 and the disclosure requirements in paragraph 36).
Who decides: management of each reporting entity chooses cost formulas (FIFO or weighted average, or specific identification where required) and makes judgement calls on NRV and, for NFPs, on the appropriate basis for loss of service potential (paragraphs 25–27; Aus9.2; BC17). Those choices affect reported carrying amounts and expense recognition (paragraphs 9 and 34).
Compliance burden and implementation risk: the Standard requires estimates (NRV, replacement cost, allocation of fixed/variable overheads) and record‑keeping to support write‑downs and reversals, including tracking the circumstances that led to a write‑down (paragraphs 12–14; 28–33; BC9). The Basis for Conclusions notes practical burdens such as maintaining historic cost, current replacement cost and prior carrying amounts where replacements are infrequent (BC9). Judgment areas (NRV, service potential assessment for NFPs) create estimation risk and a need for documented policies and disclosures (paragraphs 30–33; Aus9.2; Aus36.1(h)).
Interaction and opportunity cost: the Standard cross‑references or defers to other accounting Standards in specific areas (AASB 141 for agriculture, AASB 13 on fair value, AASB 15/AASB 1058 for certain revenues and donated or low‑cost inventories, AASB 16 for leases and AASB 123 for borrowing costs), so implementation often requires coordination across rules (paragraphs 2(c), 20, 6 and effective‑date notes 40E–40G). That coordination increases preparer effort and can create timing/transition choices (Aus42.1–Aus42.2).
Effects on private enterprise and market signals: the Standard does not set prices or constrain competition directly; it prescribes how inventories are measured and disclosed for financial reporting. Measurement choices (cost formula, write‑downs) change reported cost of goods sold and reported profit in a period (paragraphs 25–27 and 34). For sectors with industry measurement practices (agriculture, commodities), permitted alternative measurements mean reported figures may differ from entities that follow the general rule (paragraphs 3–5 and 20).

Main concepts

The Standard’s core concepts are inventory definition, measurement base, cost composition, cost assignment formulas, net realisable value assessment, write‑down and reversal mechanics, scope exceptions, and disclosure obligations. Inventories are defined as assets held for sale, in the process of production for sale, or in the form of materials/supplies to be consumed in production or rendering services (para 6). The principal measurement rule is the lower of cost and net realisable value (para 9). For not‑for‑profit entities inventories held for distribution are measured at cost, adjusted for any loss of service potential (Aus9.1), and the Basis for Conclusions explains why this shift was introduced (BC12-BC20).

Cost composition is split into costs of purchase (purchase price, import duties and taxes not recoverable, transport and handling after discounts are deducted) (para 11), costs of conversion (direct labour, systematic allocation of fixed and variable production overheads; allocation of fixed overheads based on normal capacity) (paras 12-13), and other costs that bring inventories to present location and condition (para 15). The Standard gives examples of excluded costs, such as abnormal waste, storage (unless necessary during production), administrative overheads not contributing to bringing inventories to present location/condition, and selling costs (para 16). It notes limited circumstances for capitalising borrowing costs under AASB 123 (para 17) and requires recognition of a financing element as interest when purchases on deferred settlement contain financing (para 18).

Cost assignment methods are conceptually constrained to prevent earnings management: specific identification for non‑interchangeable items and segregated project inventories (para 23), FIFO or weighted average for other inventories (para 25). Entities must use the same cost formula for inventories of similar nature and use, though different cost formulas can be used across different uses or operating segments when justified (paras 25-26).

Net realisable value (NRV) is defined as estimated selling price in the ordinary course less estimated completion and selling costs (para 6). Inventory carryings are written down to NRV when cost is not expected to be recoverable due to damage, obsolescence, price decline or increases in costs to complete/sell (para 28). The Standard permits grouping similar items for write‑downs where appropriate (para 29), requires reliable evidence for NRV estimates (para 30), addresses contract‑specific valuation for inventory held to satisfy firm sales contracts (para 31), and mandates reassessment each period and reversal of write‑downs when appropriate, limited to the amount of the original write‑down (para 33).

Scope exceptions are operational concepts: entities in certain industries may be allowed or required to measure inventories at NRV or fair value less costs to sell under established practices or active markets (paras 3-5 and 20). The Standard therefore co‑exists with AASB 141, AASB 9/132 exclusions for financial instruments, and recognises interaction with other standards on revenue and leasing (paras 2, 8, 20, 40E, 40G).

Disclosure is a central transparency mechanism: policies used, carrying amounts by classification, amounts recognised as expense, write‑downs and reversals, events causing reversals, and inventories pledged as collateral must be disclosed (para 36). Not‑for‑profit entities have added disclosure duties about inventories held for distribution, including the basis for assessing loss of service potential (Aus36.1).

Who it affects

AASB 102 applies broadly to entities preparing financial statements under Australian Accounting Standards, with tailored provisions for for‑profit, not‑for‑profit and Tier 2 (simplified disclosure) reporting entities. The Standard states it applies to all inventories except those specifically excluded (para 2). For‑profit entities that comply with AASB 102 also comply with IAS 2 (Comparison with IAS 2 section). Not‑for‑profit entities face some Australian‑specific “Aus” paragraphs that modify measurement and disclosure (Aus2.1, Aus9.1, Aus10.1-Aus10.2, Aus36.1 and Aus42.1-Aus42.2), so their compliance with IAS 2 will depend on whether Aus paragraphs provide additional or inconsistent requirements.

Specific industry or business models are singled out. Producers of agricultural and forest products, agricultural produce after harvest, and minerals and mineral products are carved out to the extent they are measured at net realisable value under well‑established industry practices; those inventories are excluded from the measurement requirements of AASB 102 (para 3(a)-4). Commodity broker‑traders whose inventories are principally acquired for near‑term resale and trading profits may measure inventories at fair value less costs to sell and are excluded from the Standard’s measurement requirements for those items (para 3(b)-5). Agricultural produce harvested from biological assets is subject to AASB 141, with fair value less costs to sell at the point of harvest treated as its cost for AASB 102 purposes (para 20).

Not‑for‑profit entities are materially affected by the Standard’s tailored rules. Aus2.1 exempts work in progress of services to be provided for no or nominal consideration from the Standard in respect of not‑for‑profit entities. Aus9.1 requires inventories held for distribution to be measured at cost adjusted for loss of service potential, and Aus36.1 imposes specific disclosure requirements including the basis on which loss of service potential is assessed. Appendix A defines not‑for‑profit entities and clarifies current replacement cost and inventories held for distribution (Aus6.1, Aus8.1-8.2), which directly affect charities, public sector service providers and similar organisations.

Entities that prepare general purpose financial statements under Tier 2 simplified disclosures are affected by Appendix B. AusB1 states that paragraphs 36-39 (key disclosure requirements) do not apply to Tier 2 entities applying AASB 1060 General Purpose Financial Statements - Simplified Disclosures, reducing the disclosure burden for smaller or simplified reporters.

Finally, the Standard interacts with other standards that materially affect who is subject to which requirement: for example AASB 15 (revenues) affects whether costs to fulfil contracts are treated as inventories (para 8); AASB 16 (leases) amended allocation of overheads (para 12 amendments noted in compilation details); and AASB 1058 modifies measurement of certain donated or heavily subsidised inventories (Aus10.1-Aus10.2). Entities must therefore map their operations against AASB 102 and these related standards to determine which paragraphs govern their reporting.

Key duties and rights

AASB 102 imposes substantive recognition, measurement and disclosure duties rather than rights. The primary duties are: measure inventories at the lower of cost and net realisable value (para 9) except where the Standard provides a different basis (Aus9.1; paras 3-5; para 20); determine and capitalise appropriate cost components (paras 10-18); assign costs using permissible formulas and apply those formulas consistently for inventories of similar nature and use (paras 23-27); assess net realisable value and recognise write‑downs and reversals in the profit or loss in line with paras 28-34; and comply with detailed disclosure obligations (para 36 and Aus36.1).

Specific obligations follow from the composition and allocation rules. Entities must include all costs of purchase, costs of conversion and other directly attributable costs in inventory cost (para 10). Costs of purchase are explicitly defined and require deduction of trade discounts, rebates and similar items (para 11). Conversion costs must include direct labour and a systematic allocation of fixed and variable production overheads, where fixed overhead allocation is based on normal capacity and not increased because of low production (paras 12-13). Entities must expense unallocated overheads and abnormal production costs (para 13, 16).

There are duties when applying alternative measurement bases. Producers and broker‑traders that measure inventories under industry practice or fair value less costs to sell must recognise changes in those measures in profit or loss in the period of change (paras 3-5). Agricultural produce at harvest is to be measured at fair value less costs to sell per AASB 141 and that fair value becomes the cost base for subsequent AASB 102 application (para 20).

For not‑for‑profit entities, duties differ. Inventories held for distribution must be measured at cost adjusted for any loss of service potential (Aus9.1), and when inventories are acquired for consideration significantly less than fair value to further the entity’s objectives, the entity shall initially measure those inventories at current replacement cost, subject to Aus10.2 materiality expedient and coordinated recognition under AASB 1058 (Aus10.1-Aus10.2). Not‑for‑profits must disclose the basis on which loss of service potential is assessed (Aus36.1(h)).

Disclosure duties are explicit and granular. Entities must disclose accounting policies and the cost formula used, total carrying amount and appropriate classifications of inventories, carrying amount of inventories carried at fair value less costs to sell, amount of inventories recognised as expense, write‑downs and reversals and events that caused reversals, and carrying amount pledged as security (para 36). Not‑for‑profit entities have parallel disclosures for inventories held for distribution (Aus36.1).

The Standard does not create direct enforcement rights or penalties within its text. It is framed to be read with AASB 1048, AASB 1057 and AASB 108 (prefatory paragraph) and is made by the AASB under section 334 of the Corporations Act 2001 (Accounting Standard section), which situates its application in the Corporations Act framework. The Standard therefore creates duties forming part of the Australian Accounting Standards regime that applies to entities subject to that legislation.

Penalties and enforcement

AASB 102 itself is an accounting standard and does not specify criminal sanctions, civil penalties or enforcement procedures in its text. The Standard records that it was made under section 334 of the Corporations Act 2001 (Accounting Standard AASB 102 section), and the prefatory material directs readers to related AASB instruments and the Corporations Act context. The Standard must be read in conjunction with AASB 1048 Interpretation of Standards, AASB 1057 Application of Australian Accounting Standards, and AASB 108 Accounting Policies, Changes in Accounting Estimates and Errors (prefatory paragraph). These cross‑references indicate that compliance with AASB 102 forms part of the broader legislative accounting framework established under the Corporations Act and related instruments.

Because the Standard does not include penalty clauses, enforcement arises through the corporate reporting and statutory audit ecosystem that enforces compliance with Australian Accounting Standards. The Standard’s compilation and effective dates (Compilation Details; para 40) and the statement that it repeals the July 2004 AASB 102 but that the repealed standard continues to apply to earlier periods (Aus42.4) indicate how the Standard fits into the statutory timeline for reporting. The Standard’s disclosure obligations (para 36; Aus36.1) and measurement rules impose responsibilities on management and on auditors in forming audit opinions in accordance with Australian auditing standards and the requirements of the Corporations Act for financial reporting.

The Standard directs entities to other AASB Standards for related measurement and recognition rules that have their own interaction with the legislative framework: AASB 141 for agricultural produce at harvest (para 20), AASB 123 on borrowing costs (para 17), and AASB 15 on costs to fulfil contracts (para 8). Where an entity elects alternative industry measurement practices recognised in the Standard (paras 3-5), the Standard states that changes under those practices are to be recognised in profit or loss in the period of change; these accounting consequences would be assessed in statutory reporting and audit processes.

In practical terms, entities subject to the Corporations Act that fail to comply with AASB 102 in preparing financial statements may face regulatory and market consequences through the statutory reporting regime, including audit qualifications, restatements and potential regulatory scrutiny. The Standard itself contains no enforcement mechanism language; it relies on the existing statutory and professional frameworks that govern compliance with Australian Accounting Standards and the Corporations Act 2001.

How it interacts with other laws

AASB 102 is explicitly framed to operate within the suite of Australian Accounting Standards and cross‑references several other standards that alter or interact with the treatment of inventories. The prefatory text instructs reading AASB 102 in the context of other Australian Accounting Standards, particularly AASB 1048, AASB 1057 and AASB 108. The Standard excludes financial instruments and points to AASB 132 Financial Instruments: Presentation and AASB 9 Financial Instruments (para 2(b)). Biological assets and agricultural produce at harvest are addressed by AASB 141 Agriculture rather than AASB 102 (para 2(c); para 20).

Industry practice exclusions interact with the Standard by allowing producers of agricultural/forest products, minerals, and commodity broker‑traders to measure inventories at net realisable value or fair value less costs to sell where well‑established practices or market conditions apply. Those inventories are excluded from AASB 102’s measurement requirements, but the Standard notes that changes under those measurement approaches are recognised in profit or loss (paras 3-5). This creates a boundary with sector practice and other standards (for example AASB 141 for biological assets).

Revenue recognition interacts with inventory treatment where costs to fulfil a contract do not give rise to inventories or other assets: those costs are accounted for under AASB 15 Revenue from Contracts with Customers (para 8). The Standard also notes the role of AASB 123 Borrowing Costs where borrowing costs are capitalised in limited circumstances (para 17), signalling that capitalisation of borrowing costs follows AASB 123 rather than AASB 102 alone.

Leases and overhead allocation interact through amendments: AASB 16 Leases amended paragraph 12, and AASB 16 is noted in the effective‑date and compilation details (40G; Compilation table). AASB 16’s treatment of right‑of‑use assets affects what constitutes production overheads (paras 12 and compilation details). AASB 1058 is cross‑referenced in the not‑for‑profit initial measurement of inventories acquired for consideration significantly less than fair value (Aus10.1-Aus10.2 and compilation details), indicating an interaction between income recognition under AASB 1058 and inventory measurement.

Other provisions interact with standards addressing impairments and provisions: AASB 137 Provisions, Contingent Liabilities and Contingent Assets governs provisions that may arise from firm sales or purchase contracts where inventory held is insufficient (para 31). The Basis for Conclusions rejected use of an AASB 136 Impairment‑style test for inventories held for distribution (BC11), explaining policy choices and conceptual alignment with the Framework (BC12-BC17).

Tiering and disclosure interaction are present. Appendix B and AusB1 exempt Tier 2 entities applying AASB 1060 from paragraphs 36-39 disclosure requirements, which reduces disclosure obligations under other legislative frameworks for eligible entities (AusB1; Compilation table listing AASB 1060). The Standard’s issuance under section 334 of the Corporations Act and its reliance on AASB 1048, 1057 and 108 situates it within the Corporations Act reporting regime (Accounting Standard AASB 102 section; prefatory paragraph), so practitioners must implement AASB 102 in concert with statutory reporting and audit requirements under corporate law.

Amendment history

The compilation details and table of standards record the amendment history included up to 20 December 2021. AASB 102 as compiled incorporates IAS 2 as amended by the IASB and includes Australian “Aus” paragraphs. The Standard as issued by the AASB was made on 24 July 2015 (Accounting Standard AASB 102 section). The compiled Standard applies to annual periods beginning on or after 1 January 2022, though earlier application was permitted (Compilation Details; para 40).

The compilation table identifies related standards and amendment milestones:

AASB 102 (original instrument) made 24 July 2015, effective periods beginning 1 January 2018 (Compilation table).
AASB 16 Leases (23 Feb 2016) amended paragraph 12 and added paragraph 40G; entities apply that amendment when they apply AASB 16 (40G; Table of amendments noting paragraph 12 amended).
AASB 1058 (9 Dec 2016) added or amended Aus10.1 and Aus10.2, governing initial measurement of inventories acquired for significantly less than fair value for not‑for‑profit entities (Table of amendments; Aus10.1 and Aus10.2).
AASB 2016‑7 deferred some effective dates for not‑for‑profit entities in relation to AASB 15 (Compilation table note (c)).
AASB 1060 (6 Mar 2020) replaced Appendix B with simplified disclosures for Tier 2 entities (Table of Standards; Compilation table (d); Table of amendments shows Appendix B replaced).
AASB 2021‑7 (20 Dec 2021) amended Aus36.1 (Table of amendments shows Aus36.1 amended by AASB 2021‑7).

The Standard repealed the July 2004 AASB 102 (Aus42.4), but that repeal does not affect earlier reporting periods: the repealed standard continues to apply to any period ending before the new Standard’s application under section 334 of the Corporations Act (Aus42.4). The Basis for Conclusions chapters document the conceptual and practical reasoning for the change in accounting for inventories held for distribution by not‑for‑profit entities (BC1-BC21), including the Board’s consideration of alternatives and the operational rationale for prospective transition (BC21). The compilation explicitly notes the incorporation of amendments up to 20 December 2021 and lists which paragraphs were amended, added or repealed (Table of amendments and Compilation Details). The Standard also retains deleted IAS 2 text for reference, noting such deleted text is not part of AASB 102 (Deleted IAS 2 text note).

Transition provisions specific to not‑for‑profit entities require prospective application of the Aus9.1 measurement requirement from the beginning of the first annual period to which the Standard is first applied by that entity, with any adjustment to opening inventories carried against opening retained earnings and without adjustment of comparative information (Aus42.1-Aus42.2; BC21 addresses rationale).

Gotchas

AASB 102 contains several technical traps and points where incorrect application commonly occurs unless the prescribed mechanics are followed and documented.

Scope misclassification. Entities may misapply the measurement rules where industry exceptions apply. Producers measuring inventories at net realisable value under “well‑established practices” and broker‑traders measuring at fair value less costs to sell are excluded from AASB 102’s measurement requirements (paras 3-5). Practitioners must document why an industry practice qualifies as “well‑established” or why a broker‑trader’s inventories meet the near‑term trading purpose; otherwise applying the Standard’s measurement rules could be incorrect.
Not‑for‑profit treatment differences. Inventories held for distribution are measured at cost adjusted for loss of service potential (Aus9.1), not at lower of cost and current replacement cost as previously required. Transition is prospective, with adjustments to opening retained earnings rather than comparatives (Aus42.1-Aus42.2; BC21). Failing to apply the Aus provisions or to disclose the basis for assessing loss of service potential (Aus36.1(h)) is a particular risk for charities and public sector entities.
Donated or subsidised inventories. Aus10.1 permits initial measurement at current replacement cost where consideration is significantly less than fair value to further the entity’s objectives, with a practical expedient for materiality at item or portfolio level (Aus10.2). Practitioners must coordinate this with AASB 1058 for income recognition and document any elections and materiality judgements.
Overhead allocation and normal capacity. Fixed production overheads must be allocated based on normal capacity, not actual reduced production levels (para 13). Entities that allocate fixed overheads over actual production when that production is below normal capacity risk over‑capitalising inventories. Defining normal capacity requires judgment and documentation.
Cost formula consistency. The Standard requires the same cost formula for inventories of similar nature and use (para 25). Using different formulas across similar inventories for tax, geography or tactical earnings reasons is non‑compliant. Geographical differences alone do not justify different formulas (para 26).
NRV measurement and reversals. NRV estimates require reliable evidence and must consider events after period end that confirm conditions at reporting date (para 30). Reversals are limited to the amount of the original write‑down (para 33). Failure to retain evidence supporting NRV estimates (sales contracts, market prices, cost forecasts) undermines auditability.
Retail method and standard costs. These techniques are allowed only if they approximate cost (paras 21-22). Inappropriately broad application of the retail method to dissimilar inventories or failure to regularly review standard costs can produce material measurement errors.
Deferred settlement arrangements. When purchase arrangements contain a financing element, the effective financing must be recognised as interest expense over the period (para 18). This can affect both initial inventory cost measurement and profit recognition if ignored.
Disclosure omissions. Paragraph 36 (and Aus36.1 for not‑for‑profit entities) sets out precise disclosure items, including inventories pledged as security (para 36(h)) and circumstances causing reversals (para 36(g)). Tier 2 reporting entities may be exempt under AusB1, but practitioners must confirm Tier eligibility and whether Appendix B applies.
Interaction with other standards. AASB 102 requires coordinate application with standards such as AASB 15 (para 8), AASB 123 (para 17), AASB 141 (para 20), AASB 137 (para 31) and AASB 16 (compilation notes amending para 12). Failure to align account boundaries and timing with these standards is a common compliance gap.

Documentary evidence, consistent policies and a written rationale for judgments (normal capacity, loss of service potential, choice of cost formula, use of alternatives for donated inventory) are practical mitigants to these gotchas. The Basis for Conclusions warns that replacement cost records can be onerous (BC9), and the Board deliberately chose prospective transition for not‑for‑profit changes to limit retrospective reconstruction (BC21).

How to comply

Compliance requires a disciplined, documented approach linking classification, measurement and disclosure to the Standard’s paragraphs and to related AASB standards.

Classify inventory and test scope. Identify each inventory line against the definitions in paragraph 6. Test whether an item falls within exclusions in paragraph 2 and paras 3-5 (financial instruments, AASB 141 biological assets, industry practices for producers and broker‑traders). For agricultural produce at harvest, apply AASB 141 and treat fair value less costs to sell at harvest as the cost base (para 20).
Select and document cost formula and techniques. For non‑interchangeable items use specific identification (para 23). For other items use FIFO or weighted average and document consistent application across inventories of similar nature and use (paras 25-26). If using standard costs or the retail method, document assumptions and periodic reviews to show results approximate actual cost (paras 21-22).
Determine cost components and capitalise correctly. Establish policy that cost comprises costs of purchase, conversion and other directly attributable costs (para 10). Define inclusion/exclusion rules for abnormal waste, storage, administrative and selling costs (para 16). For borrowing costs, follow AASB 123 where applicable (para 17). For purchases on deferred settlement, identify financing elements and recognise interest expense over the financing period (para 18).
Allocate overheads using normal capacity. Compute normal capacity based on expected production over several periods (para 13). Do not inflate unit cost because of low production; recognise unallocated overheads as period expense. Document methodology for allocating fixed and variable overheads, and for allocation across joint products or by‑products (para 14).
Assess net realisable value each reporting period. Implement procedures and evidence requirements to support NRV estimates (para 30). For inventory held to satisfy firm sales contracts, use contract price for the matched quantity and general selling prices for excess (para 31). Where materials are held for use in production, monitor finished product NRV and write down materials if replacement cost indicates finished goods NRV below cost (para 32). Maintain documentation to support reversals constraint (para 33).
Not‑for‑profit specifics. For inventories held for distribution, apply Aus9.1 and set explicit criteria to identify and measure loss of service potential, including replacement cost or obsolescence bases where relevant (Aus9.2; BC12-BC17). For inventories acquired for consideration significantly less than fair value to further objectives, consider initial measurement at current replacement cost per Aus10.1 and apply AASB 1058 for related income recognition. Elect and document any Aus10.2 materiality expedient applied.
Disclosure checklist. Prepare disclosures required by paragraph 36, and for not‑for‑profit entities the Aus36.1 additions. Ensure items disclosed include accounting policies and cost formula, carrying amounts by classification, amount recognised as expense, write‑downs and reversals and events causing reversals, and inventories pledged as security (para 36; Aus36.1). Confirm Tier 2 eligibility; if applying AASB 1060, paragraphs 36-39 may not apply (AusB1).
Transition and opening balances. For not‑for‑profit entities adopting Aus9.1, apply the measurement prospectively from the beginning of the annual period of first application and adjust opening retained earnings for any difference without restating comparatives (Aus42.1-Aus42.2).
Systems, controls and audit trail. Implement inventory accounting policies in ERP systems to capture cost allocation, overhead bases, NRV inputs, and financing elements on purchases. Retain market evidence, sales contracts, replacement cost estimates, and board minutes documenting judgments on normal capacity and loss of service potential to satisfy audit review.
Coordinate with related standards. Map inventory transactions to AASB 15 for contract fulfilment costs (para 8), AASB 123 for borrowing costs (para 17), AASB 141 for biological assets (para 20), AASB 137 for provisions arising from firm contracts (para 31), and AASB 16 where lease accounting affects production assets and overheads (compilation notes and para 12 amendment).

Documented policies, periodic review cycles for cost assumptions and NRV, and a clear audit trail for judgments will materially reduce compliance risk. Ensure the finance team and auditors agree on the interpretation of “normal capacity”, the basis for loss of service potential for not‑for‑profit inventories, and the treatment of donated inventory under Aus10.1 in conjunction with AASB 1058.
