Costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as finance part of the cost of an asset. A qualifying asset is one whose value is greater than US$5 million and requires a longer period to 12 months to get ready for its intended use. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consist of interest and other costs that the Group incurs in connection with the borrowing of funds.
