The interest cost eligible for capitalization shall be the interest cost recognized on borrowings and other obligations. The amount capitalized is to be an allocation of the interest cost incurred during the period required to complete the asset. The interest rate for capitalization purposes is to be based on the rates on the enterprise's outstanding borrowings. If the enterprise associates a specific new borrowing with the asset, it may apply the rate on that borrowing to the appropriate portion of the expenditures for the asset. A weighted average of the rates on other borrowings is to be applied to expenditures not covered by specific new borrowings.
Judgment is required in identifying the borrowings on which the average rate is based.
