For CFOs and finance managers accountable for asset-heavy balance sheets, fair value measurement is one of the most consequential — and most commonly misunderstood — requirements in Australian financial reporting.
The number that enters the financial statements is not simply a figure produced by a valuer. It is a documented, market-referenced conclusion governed by a framework of standards, classification requirements, and disclosure obligations. Each trigger for a fair value valuation creates a requirement for a valuation that is defensible, well-documented, and aligned with AASB 13 — not simply a management estimate or desk-based assessment.
This article explains how fair value is actually determined for plant and equipment — what the standard requires, when a valuation is triggered, how inputs are classified within the hierarchy, which approaches apply, and what distinguishes a report that holds up under audit from one that doesn’t.
What Fair Value Actually Means for Plant and Equipment
Fair value is defined in AASB 13 Fair Value Measurement as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” For plant and equipment, that definition demands careful unpacking.
Fair value is an exit price — it reflects what a market participant would pay to acquire the asset, not what the entity paid for it, not what the entity needs it to be worth, and not its depreciated book value. It is a market-based measurement, not an entity-specific one. The transaction is assumed to be orderly — conducted after reasonable exposure to the market, not under duress. The price is determined as at a specific measurement date, using assumptions that market participants would use.
For physical assets, AASB 13 requires the valuer to consider the asset’s highest and best use — the use that would maximise the value of the asset from a market participant’s perspective. That use must be physically possible, legally permissible, and financially feasible. In many cases for operating plant and equipment, the highest and best use will be the current use, but this is a conclusion that needs to be tested, not assumed.
The premise of value matters — and it is frequently underspecified.
AASB 13 distinguishes between two premises of value: in-use and in-exchange. An in-use premise applies where the asset provides maximum value to market participants through its use in combination with other assets as a group — for example, a processing line in a manufacturing facility. An in-exchange premise applies where the asset provides maximum value on a standalone basis — for example, a surplus piece of mobile equipment that would be sold individually.
This distinction matters because it directly affects the valuation approach, the level of obsolescence applied, and ultimately the figure that enters the financial statements. An asset valued in-use as part of a going concern operation will typically be worth materially more than the same asset valued in-exchange, stripped from its operating context. The premise adopted must be disclosed, and it must be consistent with how market participants would view the asset.
When Is a Fair Value Valuation Required?
Several events under Australian accounting and tax frameworks require plant and equipment to be measured at fair value. Understanding which trigger applies — and what it demands — is essential for scoping the engagement correctly.
Revaluation model under AASB 116. Where an entity elects the revaluation model for a class of property, plant and equipment, the carrying amount must be adjusted to fair value with sufficient regularity that it does not differ materially from the amount that would be determined using fair value at the reporting date. For many entities with material plant and equipment balances, this means engaging a valuer on a cyclical basis — and more frequently where asset values are volatile.
Purchase price allocation under AASB 3. On a business combination, the acquirer must recognise all identifiable assets acquired at their acquisition-date fair values. For asset-heavy businesses, plant and equipment often represents the largest identifiable tangible asset class requiring separate valuation. The fair values determined in a purchase price allocation directly affect the goodwill residual and, subsequently, the depreciation profile reflected in earnings.
Impairment testing under AASB 136. When indicators suggest an asset or cash-generating unit may be impaired, the entity must estimate the recoverable amount — being the higher of fair value less costs of disposal and value in use. Entities are required to ensure that their assets are carried at no more than their recoverable amount. An asset is carried at more than its recoverable amount if its carrying amount exceeds the amount to be recovered through use or sale of the asset. For impairment purposes, a reliable fair value determination provides a critical benchmark against which carrying values are tested.
Tax consolidation. When a tax consolidated group is formed, or when a new entity joins an existing group, the tax cost setting rules require a reset of asset values for income tax purposes. This frequently involves an independent fair value determination of plant and equipment to establish the reset cost base.
Stamp duty. In several Australian jurisdictions, the transfer of dutiable property — including plant and equipment in some circumstances — requires a market value determination for duty assessment purposes. The duty authority may accept or challenge the value adopted, so the robustness of the valuation directly affects the entity’s stamp duty liability.
Each of these triggers creates a requirement for a valuation that is defensible, well-documented, and aligned with AASB 13 — not simply a management estimate or desk-based assessment.

The Fair Value Hierarchy and Why It Matters to Auditors
AASB 13 establishes a three-level hierarchy that categorises the inputs used in valuation techniques, not the techniques themselves. For plant and equipment, understanding this hierarchy is essential because it determines the disclosure obligations attached to the resulting fair value measurement.
Level 1 — Quoted prices in active markets. For plant and equipment, Level 1 inputs are rarely available. There is no exchange-listed market for most industrial machinery, processing equipment, or site-specific plant. It may occasionally apply to certain standardised, mass-produced assets traded on active dealer markets, but this is the exception.
Level 2 — Observable inputs other than Level 1. Level 2 inputs include quoted prices for similar assets in active markets and other observable market data. For plant and equipment, Level 2 classifications can be supported where the valuer relies on OEM (original equipment manufacturer) pricing, published cost indices, recent arm’s-length sales of comparable equipment, or supplier quotations. This is the most common classification for well-researched, actively traded asset classes such as mobile plant and standard commercial vehicles.
Level 3 — Unobservable inputs. Level 3 applies where the significant inputs to the valuation are not directly observable in the market and must be developed by the valuer using assumptions consistent with those market participants would use. For specialised or site-specific plant — custom-built processing facilities, bespoke production lines, purpose-built infrastructure — Level 3 is frequently the appropriate classification.
A point that is often missed: the overall fair value measurement is classified in the level of the hierarchy corresponding to the lowest-level input that is significant to the entire measurement. So if a valuation uses predominantly observable cost data but relies on a significant unobservable obsolescence adjustment — for example, economic obsolescence due to a declining commodity price — the measurement is classified as Level 3 regardless of the other inputs.
Auditors focus on this classification because it directly determines the extent of financial statement disclosures required under AASB 13, including reconciliations for Level 3 measurements, sensitivity disclosures, and descriptions of the valuation techniques and inputs used. A higher concentration of Level 3 measurements increases audit effort — and a poorly documented hierarchy classification is a consistently common area where audit queries arise.
Valuation Approaches for Plant and Equipment
AASB 13 identifies three valuation approaches — market, cost, and income — and requires the use of techniques appropriate to the circumstances and for which sufficient data are available, maximising observable inputs and minimising unobservable ones. For plant and equipment, the applicability of each approach varies significantly by asset type.
Market approach. The market approach estimates fair value by reference to prices and other relevant information generated by market transactions involving identical or comparable assets. It works well for liquid, actively traded asset classes — light commercial vehicles, standard forklifts, generic mobile plant. A comparable transaction is reliable when the asset is sufficiently similar in type, age, condition, and configuration, and the transaction is recent and arm’s-length. For specialised or purpose-built assets, the market approach is typically not feasible as a primary method because comparable transactions are rare or non-existent.
Cost approach. For most plant and equipment — and particularly for specialised, site-specific, or custom-built items — the cost approach is the primary valuation method. The first step is to estimate the cost to a market participant of replacing the subject asset by reference to the lower of either reproduction or replacement cost. From this starting point, the valuer applies adjustments for obsolescence to reflect the condition and utility of the asset as at the measurement date. Physical obsolescence reflects wear and deterioration. Functional obsolescence captures over-capacity, design limitations, or superseded technology. Economic obsolescence accounts for external factors — regulatory changes, commodity price shifts, declining market demand — that reduce the utility or value of the asset irrespective of its physical condition. Each adjustment must be separately identified and documented.
Income approach. The income approach is generally not appropriate for individual items of plant and equipment. Although applicable where cash flows can be identified for the asset or a group of complementary assets, it is typically difficult to separate cash flows attributable to plant and equipment without including cash flows associated with intangible assets. Attributing a discrete income stream to a single physical asset within an integrated production system is rarely feasible — the income approach is more commonly applied at the cash-generating unit or business enterprise level.
Approach selection is a technical judgement, not a default.
A valuation engagement covering a diverse asset register — spanning everything from standard vehicles to custom-engineered processing plant — should not default to one method across the board. Where comparable transactions are rare, the choice of approach carries more weight, not less. Under the standards, the reasoning for that choice is documented and open to scrutiny.
On the practical question of managing large or complex asset registers, valuation modelling plays an important role. Structured models allow the valuer to apply consistent methodology across potentially thousands of line items, stratify the register by asset class and risk profile, and ensure that key inputs — remaining useful life estimates, obsolescence rates, replacement cost indices — are applied systematically rather than ad hoc. For CFOs and auditors, the quality and transparency of the underlying model is often as important as the individual asset values it produces.
A valuation that survives audit scrutiny is not necessarily one that reaches a particular number — it is one where the number is defensible.
What Makes a Valuation Audit-Ready
That defensibility rests on documentation, evidence, and process.
Clear documentation of assumptions. Every material assumption must be explicitly stated and supported: the premise of value, the hierarchy classification for each significant asset class, the data sources relied upon, the approach selected and why. AASB 13 and IVS 106 both require transparency in reporting. If professional judgement has been applied — and in plant and equipment valuations it frequently has — the nature and basis of that judgement must be disclosed, not embedded within a black-box model.
Independent site inspection. Condition, utilisation, and obsolescence cannot be properly assessed from a desk. A physical inspection allows the valuer to verify asset existence, confirm condition ratings, identify items not on the register, and assess whether the operating environment supports the assumptions underpinning the valuation.
Market evidence. For Level 2 classifications to be sustained, there must be a clear trail of observable market evidence — OEM pricing data, supplier quotations, published cost benchmarks, or comparable sales transactions. Without this evidence, the auditor will reasonably challenge the hierarchy classification, potentially reclassifying the measurement to Level 3 with the attendant additional disclosure requirements.
Common audit challenges. Auditors routinely challenge: unsupported useful life assumptions that diverge materially from prior periods without explanation; obsolescence adjustments applied as a blanket percentage without asset-specific rationale; missing or incomplete hierarchy disclosures; and a lack of comparables or market evidence to support adopted values. Each of these represents a transparency gap — and each is avoidable with a properly scoped and executed valuation engagement.
Valuation engagement vs. calculation engagement. APES 225 Valuation Services distinguishes between a valuation engagement — where the valuer selects the approach, method, and significant inputs and applies professional judgement to arrive at a conclusion of value — and a calculation engagement, where the scope is more limited and the valuer does not exercise full independent judgement. The level of reliance that can be placed on the output differs materially. A valuation engagement produces a conclusion of value. A calculation engagement produces a calculated result that is explicitly not a valuation opinion. For financial reporting purposes, a valuation engagement is the appropriate standard. Entities commissioning valuations should ensure the engagement letter and scope of work are structured accordingly.
Note: APES 225 was revised in October 2024 and is effective for Valuation Services commencing on or after 1 January 2025. The engagement type definitions above reflect the current edition.
The Standard Is the Starting Point, Not the Finish Line
Compliance with AASB 13 is a baseline requirement, not a differentiator. What separates a valuation that genuinely reduces audit risk from one that merely ticks a box is the rigour applied at every step — from scoping the premise of value before work begins, to building a model transparent enough for an auditor in any jurisdiction to follow.
