2. Explanation of revisions

The ordinary profit and net income forecasts were revised downward primarily due to expected losses related to floods in Thailand.*3

*Note 3:

The extent of the expected losses is currently under survey and thus difficult to reasonably estimate at this point in time. As of the date of this announcement, the expected net incurred loss is estimated to be approximately 100 billion yen, however, the actual net incurred loss may materially differ depending on how the situation develops.
