Prior to this additional acquisition, Mitsui confirmed that the acquisition of its shares had been conducted through a wholly owned subsidiary of Berkshire Hathaway Inc., National Indemnity Company.

However, once we are able to confirm the number of voting rights (number of shares held) before and after the change and the percentage relative to the total voting rights of all shareholders through amendments to large shareholding reports or other disclosures, we will make a separate announcement.
