2. Explanation of revisions

The ordinary profit and net income forecasts are revised downward primarily because the Company expects incurred losses (*1,*2) attributable to the Great East Japan Earthquake to be approximately 90.0 billion yen to the whole Tokio Marine group, and an expected increase in certain overseas consolidated subsidiaries' incurred losses attributed to the 2011 Christchurch Earthquake.

*1: The net amount remaining after deduction of an estimated recoverable amount from ceded reinsurance.
*2: Excluding the amounts of earthquake insurance under "Act on Earthquake Insurance" as they have no effect to profit/loss of the Company.
