• For each data from FY2016 to FY2018, the upper row is the Idemitsu Group and the lower row is the Showa Shell Group. (The Showa Shell Group's FY2018 results are reported for 15 months from January 2018 to March 2019.)
• FY2019 data is for the Idemitsu Group. Idemitsu Kosan and Showa Shell merged in April 2019, and the data is after the business integration.
• The scope of data for FY2019 is Idemitsu Kosan and consolidated subsidiaries. However, the reporting scope of some data point differs from the others. For details, please refer to the notes for each data point.
• Due to revisions of data calculation conditions for FY2019 along with the business integration, the combined data of both companies before FY2018 is unavailable. (From FY2016 to FY2018, there are differences in the calculation conditions of the Idemitsu Group and Showa Shell Group.
