May 31, 2000 Update on Preparations for the Merger of Sumitomo Marine and Mitsui Marine Reciprocal Use of Claims Survey Subsidiaries Reciprocal use of our two firms' claims survey subsidiaries, The Sumitomo Kaijyo Claims Services(Motor) Co., Ltd. and Mitsui Kaijyo Motor Claims Adjusters & Co., Ltd. began in May in the Tohoku and Kyushu regions. Plans also call for reciprocal use of these subsidiaries nationwide in the months ahead. Our respective accident-support networks will be mutually extended as a result, which will in turn enable us to conduct speedier investigations into traffic accidents and provide faster and more efficient claims services.
