Property Valuation for Financial Reporting

AASB 140 (Investment Property) is the Australian Accounting Standard that governs property held by an entity to earn rental income, for capital appreciation, or both — as distinct from owner-occupied property used in the entity's own operations, which falls under AASB 116 (Property, Plant and Equipment). The standard mirrors IAS 40 of the International Financial Reporting Standards framework, so any entity reporting under Australian Accounting Standards — ASX-listed entities, registered managed investment schemes, large proprietary companies, APRA-regulated funds — must comply with AASB 140 for any investment property held on the balance sheet.

Under AASB 140, entities choose between two measurement models for their investment property portfolio, applied consistently across every investment property asset. The fair value model recognises changes in the property's fair value directly in profit or loss at each reporting date, requiring up-to-date market valuations every reporting period. The cost model carries the property at historical cost less accumulated depreciation and impairment, but still requires disclosure of fair value in the notes to the financial statements. Most active Australian investors in commercial property — listed REITs, infrastructure funds, large corporates with significant property holdings — elect the fair value model, because it produces a balance sheet that reflects current market conditions and supports better investment decision-making.

AASB 140 is the operating reality for a well-defined set of Australian reporting entities. ASX-listed REITs apply it to their full property portfolios, with semi-annual or quarterly revaluation cycles common given their continuous-disclosure obligations under ASX Listing Rule 3.1. Property fund managers and registered managed investment schemes apply it across investor portfolios to support unit pricing. Corporate balance sheets carrying investment property — parent companies with property subsidiaries, holding companies, family offices structured around property entities — apply it to the relevant assets. Government entities, particularly state property authorities, apply it to land bank holdings and surplus property. APRA-regulated super funds with direct property allocations apply it within their broader prudential reporting framework.

A defensible AASB 140 fair value valuation operates within the AASB 13 fair value hierarchy. Most Australian investment property valuations sit at Level 2 (observable comparable sales evidence) for standard residential, commercial, and retail assets, or Level 3 (significant unobservable inputs — typically discounted cash flow models, market rent assumptions, and capitalisation rate selections) for specialised assets such as industrial sub-types, agricultural land, or trophy commercial property with few comparable transactions. Auditors scrutinise the inputs at each level, the sensitivity disclosures around key unobservable inputs, and the independence and professional competence of the valuer. RICS Red Book Global Standards 2025 align directly with the AASB 13 hierarchy and IAS 40 measurement principles, so a Landmark report is structured to satisfy both the accounting standard and the audit review process from day one.

AASB 140 does not mandate a specific revaluation frequency. The carrying amount under the fair value model must reflect market conditions at the reporting date, which leaves the detail to industry practice. That practice has converged on annual external revaluation for stable portfolios, with desktop updates between full inspections; quarterly or semi-annual revaluation for ASX-listed REITs subject to continuous disclosure; and full external revaluation triggered by material market movement — significant capitalisation rate shifts, major tenancy events, zoning changes, or M&A activity. Our financial reporting engagements typically structure a rolling program that aligns with the client's financial reporting calendar, blending external revaluations for the largest assets with desktop reviews for stable lower-value holdings.
