MOL Shares to Be Included in Corporate Governance Pension Fund

TOKYO - Mitsui O.S.K. Lines, Ltd. (MOL, President: Akimitsu Ashida) today announced that the company's shares will be included in the corporate governance fund created in March by the Pension Fund Association, which manages Japan's largest employee pension fund. This ¥10 billion fund will invest equal amounts in shares of 43 companies selected for their excellent corporate governance.

The fund selected its target companies with a questionnaire survey of 1,546 companies listed on the first tier of the Tokyo Stock Exchange and follow-up interviews with those scoring highest. The main evaluation items consist of "shareholder value-oriented management," "information disclosure and accountability," "board of directors," "board members' compensation systems," and "compliance and risk management." MOL is the only company selected from the transportation sector.

MOL's efforts in corporate social responsibility (CSR) and corporate governance have also resulted in the company's inclusion in major indexes for socially responsible investment (SRI) funds - the Dow Jones Sustainability Indexes, the FTSE4Good Global Index, and the Morningstar Socially Responsible Investment Index - as well as a Green Top Runner environmental rating from the Sustainability Management Rating Institute.

MOL continues to promote a highly transparent management style to enhance corporate governance.
