The interest expenses of long-term loans during the preparation period shall be included in the management expenses; 2. Interest expenses of long-term loans during the operating period are included in financial expenses; 3. If long-term loans are used to purchase and build fixed assets, the amount of interest expenses that should be capitalized before the fixed assets reach the scheduled usable state shall be included in the cost of construction in progress; 4. Interest expenses that occur after the fixed assets reach the intended usable state and are not capitalized according to regulations are included in financial expenses. Therefore, the long-term loan interest expenses during the production and operation of enterprises should be included in the financial expenses.
