Explanation:
Capital expenditure refers to costs incurred to acquire or improve a long-term asset. Interest payable on a loan specifically used for the construction of property, plant, and equipment (PPE) is considered part of the cost of that asset under IAS 23 (Borrowing Costs) and is capitalized. Other expenses like penalties, legal fees, or bonuses are considered operating costs and are classified as revenue expenditure.
