[1] | The shares were acquired through a debt-to-equity conversion during the year ended December 31, 2023, in accordance with the corporate rehabilitation procedures of BDI Co., Ltd. Since the Company has no capacity to exercise significant influence until the rehabilitation procedures are complete, the Company has classified the investment as financial assets measured at fair value through other comprehensive income.
[2] | The Company used initial cost as their fair value because there was not enough information to determine fair value, and the range of the estimated fair value is wide.
[3] | The Company has estimated the fair value of Set Holding by using the discounted cash flow method and has recognized the difference between its fair value and book value as gain or loss on valuation of financial assets at FVOCI in other comprehensive income or loss during the year ended December 31, 2023.
[4] | The Company has estimated the fair value of Set Holding by using the discounted cash flow method and has recognized the difference between its fair value and book value as gain or loss on valuation of financial assets at FVOCI in other comprehensive income or loss during the year ended December 31, 2022.
[5] | The investee declared bankruptcy during the year ended December 31, 2023. The Company has no capacity to exercise significant influence on the investee due to the receivership of the investee by a trustee in bankruptcy, so the investment was reclassified as financial assets measured at fair value through other comprehensive income.
