  • The ENEOS Group renamed two reporting segments to better reflect actual business conditions. Accordingly, "Petroleum Refining and Marketing" was renamed "Energy", while "Oil and Natural Gas Exploration and Production" remained the same in English (i.e., only the Japanese name was changed). These were changes only to the names thereof; therefore, the segment information was not affected by these changes.
