The Company has potentially issuable common shares due to its exchangeable bonds as of December 31, 2023, 2024 and 2025 and Share-based Payment Program as of December 31, 2023. The effect from the Share-based Payment Program was excluded from the calculation of diluted earnings per share for year ended December 31, 2023 due to anti-dilutive effect. Meanwhile, diluted earnings per share is equal to basic earnings per share for the years ended December 31, 2023 and 2025 due to anti-dilutive effect. Diluted earnings per share for the years ended December 31, 2023, 2024 and 2025 are calculated as follows:
