[Reason for revisions]

Consolidated ordinary profit ended with an upturn from the previous announcement because of improved equity in earnings of affiliates resulted from a re-evaluation of tax effect accounting due to the tax system revision for some equity-method affiliated companies, as well as an increased number of FPSO (Floating Production Storage and Offloading System) operating days for the Offshore Business, steady performance of the tanker market, and decreased temporary transitional costs related to the integration of the containership business.
