Change in the inventory valuation method accompanying the renewal of the core system

「The Group had previously used the cost method based on the weighted-average method for finished products included in inventories, with book values on the balance sheet written down based on a decline in profitability. For raw materials, the Group had primarily used the cost method based on the weighted-average method, with book values on the balance sheet likewise written down based on a decline in profitability. From the interim consolidated accounting period, the Group changed to the cost method based on the moving-average method for both finished products and raw materials, with book values on the balance sheet written down based on a decline in profitability. This change in the valuation method was made in connection with the renewal of the core system, with the aim of calculating periodic profit and loss more promptly and appropriately. The impact of this change was immaterial.」
