Segment determination and explanation of the measurements |
Segment determination and explanation of the measurements
The Company’s operating segments are its business components that generate discrete financial information that is reported to and regularly reviewed by chief operating decision makers of the Company including but not limited to the Chief Executive Officer, for the purpose of resource allocation and assessment of segment performance. The Company’s reportable segments are ‘Transmission and distribution’, ‘Electric power generation (Nuclear)’, ‘Electric power generation (Non-nuclear)’, ‘Plant maintenance & engineering service’ and ‘Others’; others mainly represent the business unit that manages the Company’s foreign operations. Segment operating profit (loss) is determined the same way that consolidated operating profit is determined under IFRS without any adjustment for corporate allocations. The accounting policies used by each segment are consistent with the accounting policies used in the preparation of the consolidated financial statements. Segment assets and liabilities are determined based on separate financial statements of the entities instead of on a consolidated basis. There are various transactions between the reportable segments, including sales of property, plant and equipment and so on, that are conducted on an arm’s-length basis at market prices that would be applicable to an independent third party. For subsidiaries which are in a different segment from that of its immediate parent company, their carrying amount in separate financial statements is eliminated in the consolidating adjustments in the tables below. In addition, consolidation adjustments in the table below include adjustments of the amount of investment in associates and joint ventures from the cost basis amount reflected in segment assets to that determined using equity method in the consolidated financial statements.
