[Reference] Plans for future capital management

We started to repurchase and cancel our own shares (common shares) in the first half of fiscal 2007 for the purpose of, among other things, offsetting the potential dilutive effects, considering the possibility that the number of issued and outstanding shares of our common stock will increase after the commencement of the conversion period (from July 1, 2008) of the Eleventh Series Class XI Preferred Stock (the “convertible preferred stock issued to the private sector”, 943.7 billion yen in aggregate issue amount)*. As we explained in our other disclosures, including the announcement titled “Announcement Regarding Repurchase of Own Shares (Common Shares)” dated May 22, 2007, we will continue to address the potential dilutive effects in relation to the convertible preferred stock issued to the private sector even after the redemption of the aforementioned non-dilutive preferred debt securities, aiming to complete the process in about two years, by establishing additional repurchase limits and repurchasing and canceling our own shares based on market conditions, our earning trends and other factors.

(*) Regarding the ownership of the convertible preferred stock issued to the private sector, “securities companies” and “foreign investors” in aggregate accounted for approximately 25% (in terms of the number of the issued and outstanding shares) of the 943.7 billion yen in aggregate issue amount, as recorded in the list of shareholders as of the end of March 2008.

(Additional information regarding the breakdown of the ownership of our common and preferred stocks will be disclosed in the relevant section of the “Yukashoken-Houkokusho”, or the annual securities report which will be filed in June 2008 under the Financial Instruments and Exchange Law in Japan.)
