What is a qualifying asset for borrowing cost capitalisation under IAS 23?

Under IAS 23, borrowing costs that are directly attributable to the acquisition, construction, or production of a qualifying asset must be capitalised as part of that asset's cost — expensing them is not permitted (IAS 23.8). The IAS 23 Qualifying Asset Definition is the gateway to the entire capitalisation regime. An asset qualifies only when it necessarily takes a substantial period of time to get ready for its intended use or sale (IAS 23.5). There is no bright-line threshold in the standard; judgement is required, though practice commonly treats periods exceeding 12 months as substantial. - Asset classes that typically qualify (IAS 23.7): manufacturing plants, power-generation facilities, investment property under construction, intangible assets developed internally, and inventories that require a substantial production period (e.g., aged whisky, large ship-building contracts). Assets that are routinely manufactured or produced in large quantities on a repetitive basis are explicitly excluded (IAS 23.4). - Commencement of capitalisation requires three conditions to be simultaneously met (IAS 23.17): (i) expenditures on the asset are being incurred, (ii) borrowing costs are being incurred, and (iii) activities necessary to prepare the asset for its intended use or sale are in progress. "Activities" extend beyond physical construction — they include technical and administrative work such as obtaining permits (IAS 23.19). - Capitalisation rate for general borrowings: where funds are drawn from a general borrowing pool, the rate applied is the weighted-average rate of all borrowings outstanding during the period, excluding specific borrowings (IAS 23.14). The amount capitalised cannot exceed actual borrowing costs incurred in the period (IAS 23.14 cap).

How is the weighted-average capitalisation rate calculated when borrowings are drawn and repaid at different dates during the construction period?

- Suspension: capitalisation is suspended during extended periods of active development interruption (IAS 23.20). Routine administrative delays or temporary interruptions that are an inherent part of the process do not trigger suspension (IAS 23.21). - Cessation: capitalisation stops when substantially all activities necessary to prepare the asset are complete (IAS 23.22). For assets completed in parts where each part can be used independently, cessation applies part-by-part (IAS 23.23). - Disclosure (IAS 23.26): entities must disclose the amount of borrowing costs capitalised during the period and the capitalisation rate used for general borrowings. Scenario: A manufacturer begins constructing a dedicated production facility on 1 January 20X1. Construction costs of €12,000,000 are incurred evenly throughout the year. The company has two loans outstanding: a specific loan of €5,000,000 at 6% p.a. drawn specifically for this project, and general borrowings of €20,000,000 at 8% p.a. Step 1 – Specific borrowing cost: €5,000,000 × 6% = €300,000

How should capitalisation be treated when construction of a qualifying asset is suspended for three months due to a contractual dispute — active interruption or inherent delay?

- Failing to apply the capitalisation cap on general borrowings: The weighted-average rate applied to eligible expenditure must never result in capitalised costs exceeding actual borrowing costs incurred in the period (IAS 23.14). This is a frequent exam trap and a real audit adjustment trigger when general pool rates are high but actual spend is low. - Incorrectly continuing capitalisation after substantial completion: Finance teams often carry on capitalising during minor snagging or commissioning phases. IAS 23.22 requires cessation when substantially all activities are complete — "substantially" does not mean 100%, so late-stage punch-list work should not extend the capitalisation window. - IAS 23.5 — definition of a qualifying asset (substantial period of time) - IAS 23.8 — mandatory capitalisation requirement (no option to expense) - IAS 23.14 — capitalisation rate for general borrowings and the cap on capitalised amounts - IAS 23.17 — three conditions for commencement of capitalisation - IAS 23.22–23 — cessation of capitalisation, including part-by-part rules - IAS 23.26 — minimum disclosure requirements (amount capitalised, capitalisation rate)

IAS 23 Qualifying Asset Definition

IAS 23 Qualifying Asset Definition — Core Rule

Under IAS 23, borrowing costs that are directly attributable to the acquisition, construction, or production of a qualifying asset must be capitalised as part of that asset's cost — expensing them is not permitted (IAS 23.8).

How IAS 23 Qualifying Asset Definition Works

The IAS 23 Qualifying Asset Definition is the gateway to the entire capitalisation regime. An asset qualifies only when it necessarily takes a substantial period of time to get ready for its intended use or sale (IAS 23.5). There is no bright-line threshold in the standard; judgement is required, though practice commonly treats periods exceeding 12 months as substantial.

Asset classes that typically qualify (IAS 23.7): manufacturing plants, power-generation facilities, investment property under construction, intangible assets developed internally, and inventories that require a substantial production period (e.g., aged whisky, large ship-building contracts). Assets that are routinely manufactured or produced in large quantities on a repetitive basis are explicitly excluded (IAS 23.4).

Commencement of capitalisation requires three conditions to be simultaneously met (IAS 23.17): (i) expenditures on the asset are being incurred, (ii) borrowing costs are being incurred, and (iii) activities necessary to prepare the asset for its intended use or sale are in progress. "Activities" extend beyond physical construction — they include technical and administrative work such as obtaining permits (IAS 23.19).

Capitalisation rate for general borrowings: where funds are drawn from a general borrowing pool, the rate applied is the weighted-average rate of all borrowings outstanding during the period, excluding specific borrowings (IAS 23.14). The amount capitalised cannot exceed actual borrowing costs incurred in the period (IAS 23.14 cap).

Suspension: capitalisation is suspended during extended periods of active development interruption (IAS 23.20). Routine administrative delays or temporary interruptions that are an inherent part of the process do not trigger suspension (IAS 23.21).

Cessation: capitalisation stops when substantially all activities necessary to prepare the asset are complete (IAS 23.22). For assets completed in parts where each part can be used independently, cessation applies part-by-part (IAS 23.23).

Disclosure (IAS 23.26): entities must disclose the amount of borrowing costs capitalised during the period and the capitalisation rate used for general borrowings.

IAS 23 Qualifying Asset Definition — Practical Example

Scenario: A manufacturer begins constructing a dedicated production facility on 1 January 20X1. Construction costs of €12,000,000 are incurred evenly throughout the year. The company has two loans outstanding: a specific loan of €5,000,000 at 6% p.a. drawn specifically for this project, and general borrowings of €20,000,000 at 8% p.a.

Step 1 – Specific borrowing cost: €5,000,000 × 6% = €300,000

Step 2 – Eligible expenditure for general borrowings: Average expenditure funded by general borrowings = (€12,000,000 average spend) – €5,000,000 specific = €7,000,000

Step 3 – General borrowing cost: €7,000,000 × 8% = €560,000

Total borrowing costs to capitalise: €860,000

Journal entry at 31 December 20X1

Account	Dr (€)	Cr (€)
Property, Plant & Equipment – WIP	860,000
Finance costs (P&L)	—
Interest payable / Cash		860,000

The €860,000 is added to the asset's cost base; only borrowing costs in excess of this amount (if any) would be expensed.

IAS 23 Qualifying Asset Definition — Common Pitfalls

Misclassifying routine inventory as a qualifying asset: Standard consumer goods produced in large batches are explicitly excluded (IAS 23.4). Auditors will challenge capitalisation on inventory unless the production cycle is demonstrably substantial and non-repetitive — aged wines, bespoke vessels, and complex software platforms are common borderline cases.

Failing to apply the capitalisation cap on general borrowings: The weighted-average rate applied to eligible expenditure must never result in capitalised costs exceeding actual borrowing costs incurred in the period (IAS 23.14). This is a frequent exam trap and a real audit adjustment trigger when general pool rates are high but actual spend is low.

Incorrectly continuing capitalisation after substantial completion: Finance teams often carry on capitalising during minor snagging or commissioning phases. IAS 23.22 requires cessation when substantially all activities are complete — "substantially" does not mean 100%, so late-stage punch-list work should not extend the capitalisation window.
