2. Explanation of revisions

The downward revision of forecasted ordinary income and of net income is primarily due to expected increases in investment expenses and in losses from financial guarantee reinsurance, both of which are attributable to the decline of the domestic stock market and turbulence in the global financial markets. The main components of these increases are expenses incurred due to revaluations of (i) securities, (ii) monetary receivables bought and (iii) credit default swaps, in the amounts of 31 billion yen, 17 billion yen and 9 billion yen, respectively, and losses arising from financial guarantee reinsurance of 10 billion yen.

A revised business forecast of the Company for the fiscal year ending March 31, 2009 is expected to be announced on November 19, 2008, which will be the same date that the Company expects to announce its business results for the six months ended September 30, 2008.
