In case of joint capital borrowings, which are used for the purpose of investment in construction or production of an uncompleted asset, the borrowing costs eligible for capitalization in each accounting period shall be determined according to the capitalization rate for weighted average accumulated costs incurred to the investment in construction or production of such asset. The capitalization rate shall be calculated according to the weighted average interest rate applicable to the enterprise’s borrowings unrepaid in the period, except for particular borrowings for purpose of obtaining an uncompleted asset. The amount of borrowing costs capitalized during a period must not exceed the amount of borrowing costs arising during that period.
