MS&AD Holdings Announces Conversion of Mitsui Sumitomo MetLife Insurance Company
into a Wholly Owned Subsidiary

The Board of MS&AD Insurance Group Holdings, Inc. (“MS&AD Holdings”) held on October 29, 2010 resolved the terms and conditions to acquire all shares of Mitsui Sumitomo MetLife Insurance Company, Ltd. (“MSI Met”) subject to approvals from applicable governmental authorities and executed a Share Purchase Agreement with MetLife Worldwide Holdings, Inc. (“MetLife Worldwide”), a subsidiary of MetLife, Inc. (“MetLife”), to convert MSI Met into a wholly owned subsidiary, as follows:


1.		Reasons for Conversion into a Wholly Owned Subsidiary

Our group positions life insurance business as an important growing business segment and since entering the individual annuity insurance market with MSI Met in 2002, we have achieved a steady growth in its business and MSI Met has established a firm status in the market as a leading company.
As MetLife expects to complete its acquisition of American Life Insurance Company in 2010, we have reached to an agreement on acquisition of MSI Met’s shares held by MetLife Worldwide upon closing, on or about April 1, 2011.
Through the conversion of MSI Met into a wholly owned subsidiary, we believe the solid coordination within our group to be enhanced.
MSI Met, as a core subsidiary in the group, will leverage the know-how and relationship with financial institutions and serve products that fit client’s needs in order to further enhance a position in the individual annuity insurance market.
Meanwhile, MetLife and MS&AD Holdings have agreed to continue and maintain a strong business relationship globally.


2.		Changes of Corporate Name through the Conversion of MSI Met into a Wholly Owned Subsidiary

MSI Met’s corporate name is planned to be changed upon closing, on or about April 1, 2011. It will be announced as soon as a decision is made.


3.		Details of Share Purchase

MS&AD Holdings will acquire all of the shares held by MetLife Worldwide, a subsidiary of MetLife, upon closing, on or about April 1, 2011.
Aggregate purchase price of the shares (both common shares and perpetual non-voting common shares) representing a 50% economic interest in the company is approximately 22.5 billion yen.
