2. Reasons for Revision

As a result of reflecting the impact of crude oil prices and exchange rates, the cost of raw materials is expected to fall below the previous estimate, leading to operating profit exceeding the previous forecast. While there are some downward impacts due to exchange rate valuation and other factors, ordinary profit and profit attributable to owners of parent are expected to exceed the previous forecast.
