With respect to the credit investments in securitization products made as an alternative to loans by the European and North American offices of our domestic consolidated banking subsidiaries, given the current situation in which the volume of actual transactions is extremely limited and there exists a considerable gap between the offers and bids of sellers and buyers, we determined that valuations obtained from brokers and information vendors cannot be deemed to be the fair value, and we applied reasonably calculated prices based on the reasonable estimates of our management as fair value. As a result, for the first quarter of fiscal 2009, compared to applying valuations obtained from brokers and information vendors as fair value, Ordinary Income increased in Europe by ¥920 million, and Ordinary Losses decreased in Europe by ¥16,704 million.

(Additional Information)

1. Floating-rate Japanese Government Bonds

For Floating-rate Japanese Government Bonds within Securities, based on our determination that current market prices may not reflect fair value due to the extremely limited volume of actual transactions, our domestic consolidated banking subsidiaries and a domestic consolidated trust banking subsidiary have applied reasonably calculated prices as book value for the first quarter of fiscal 2009.

As a result, compared to applying market price as book value, Securities increased by ¥99,013 million, Deferred Tax Assets decreased by ¥17,241 million, Net Unrealized Gains on Other Securities, net of Taxes increased by ¥77,981 million and Minority Interests increased by ¥3,791 million.

In deriving the reasonably calculated price, we used the Discounted Cash Flow Method as well as other methods. The price decision variables include the yield of 10-year Japanese Government Bonds and the volatilities of interest rate swap options for 10-year Japanese Government Bonds as underlying assets.

2. Securitization Products

With respect to the credit investments in securitization products made as an alternative to loans by the European and North American offices of our domestic consolidated banking subsidiaries, given the current situation in which the volume of actual transactions is extremely limited and there exists a considerable gap between the offers and bids of sellers and buyers, we determined that valuations obtained from brokers and information vendors cannot be deemed to be the fair value, and we applied reasonably calculated prices based on the reasonable estimates of our management as fair value.

As a result, as of June 30, 2009, compared to applying valuations obtained from brokers and information vendors as fair value, Securities increased by ¥176,597 million, Net Unrealized Gains on Other Securities, net of Taxes increased by ¥33,289 million, and Deferred Tax Assets decreased by ¥8,640 million. In addition, for the first quarter of fiscal 2009, Other Operating Income increased by ¥920 million, losses due to the discontinuation of business regarding credit investments primarily in Europe within Other Ordinary Expenses increased by ¥177 million, and Other Operating Expenses decreased by ¥15,961 million, which led to a decrease in Ordinary Losses of ¥16,704 million.

The book value that was reasonably calculated based on the reasonable estimates of our management mentioned above is ¥550,478 million. In deriving reasonably calculated prices based on the reasonable estimates of our management mentioned above, we used the Discounted Cash Flow Method. The price decision variables include default rates, recovery rates, pre-payment rates and discount rates, and the subject Securities included Residential Mortgage-Backed Securities, Collateralized Loan Obligations, Commercial Mortgage-Backed Securities and other Asset Backed Securities.
