  2. Reasons for the Revision to Dividend Forecast

We place importance on returning profits to our shareholders. Taking into account stable and continuous profit returns and level of internal reserves, our mid-term target for the dividend payout ratio is 40% or more of consolidated net income.

In line with our policy, we will revise the year-end dividend forecast for the current period from the previously announced 30 yen to 36 yen, an increase of 6 yen. As a result, the annual dividend per share, including the interim dividend of 30 yen, is expected to be 66 yen.
