The objective of IAS 23 is to prescribe the accounting treatment for borrowing costs. Borrowing costs include interest on bank overdrafts and borrowings, amortisation of discounts or premiums on borrowings, finance charges on finance leases and exchange differences on foreign currency borrowings where they are regarded as an adjustment to interest costs.
Borrowing cost may include: [IAS 23.6]
interest expense calculated by the effective interest method under IAS 39,
finance charges in respect of finance leases recognised in accordance with IAS 17 Leases, and
exchange differences arising from foreign currency borrowings to the extent that they are regarded as an adjustment to interest costs
This standard does not deal with the actual or imputed cost of equity, including any preferred capital not classified as a liability pursuant to IAS 32. [IAS 23.3]
A qualifying asset is an asset that takes a substantial period of time to get ready for its intended use or sale. [IAS 23.5] That could be property, plant, and equipment and investment property during the construction period, intangible assets during the development period, or "made-to-order" inventories. [IAS 23.6]
Scope of IAS 23 (2007)
Two types of assets that would otherwise be qualifying assets are excluded from the scope of IAS 23:
qualifying assets measured at fair value, such as biological assets accounted for under IAS 41 Agriculture
inventories that are manufactured, or otherwise produced, in large quantities on a repetitive basis and that take a substantial period to get ready for sale (for example, maturing whisky)
Borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset form part of the cost of that asset and, therefore, should be capitalised. Other borrowing costs are recognised as an expense. [IAS 23.8]
The foregoing reflects revisions to IAS 23 adopted by the IASB in March 2007 that prohibit immediate expensing of borrowing costs. Those revisions are effective for borrowing costs relating to qualifying assets for which the commencement date for capitalisation is on or after 1 January 2009. Earlier application is permitted.
Until that revision was effective, an entity could apply the previous version of IAS 23, which permitted, as an accounting policy option, the 'immediate expensing model'. Under that model, all borrowing costs should be expensed in the period in which they are incurred.
Where funds are borrowed specifically, costs eligible for capitalisation are the actual costs incurred less any income earned on the temporary investment of such borrowings. [IAS 23.12] Where funds are part of a general pool, the eligible amount is determined by applying a capitalisation rate to the expenditure on that asset. The capitalisation rate will be the weighted average of the borrowing costs applicable to the general pool. [IAS 23.14]
Capitalisation should commence when expenditures are being incurred, borrowing costs are being incurred and activities that are necessary to prepare the asset for its intended use or sale are in progress (may include some activities prior to commencement of physical production). [IAS 23.17-18] Capitalisation should be suspended during periods in which active development is interrupted. [IAS 23.20] Capitalisation should cease when substantially all of the activities necessary to prepare the asset for its intended use or sale are complete. [IAS 23.22] If only minor modifications are outstanding, this indicates that substantially all of the activities are complete. [IAS 23.23]
Where construction is completed in stages, which can be used while construction of the other parts continues, capitalisation of attributable borrowing costs should cease when substantially all of the activities necessary to prepare that part for its intended use or sale are complete. [IAS 23.24]
