[1] | Although the ownership percentages are less than 20%, the Group applies the equity method accounting since it participates in policy-making processes and therefore can exercise significant influence on investees.
[2] | As the financial statements as of December 31, 2025 were not available, the most recent financial statements available after the reporting date were used in applying the equity method. Significant transactions and events that occurred during the period have been appropriately reflected.
[3] | Excluded from the investments in associates due to full or partial disposal of shares, or loss of significant influence.
[4] | Shares were acquired through a debt-to-equity swap during the rehabilitation process. Although voting rights could not be exercised during the rehabilitation process, normal voting rights became exercisable as the rehabilitation process ended before December 31, 2025. Therefore, it has been reclassified from financial assets measured at fair value through profit or loss(FVTPL) to investments in associates.
[5] | As a limited partner, the Group does not have an ability to participate in policy-making processes to obtain economic benefit from the investees that would allow the Group to control the entity.
[6] | The rate of Group’s voting rights is 4.65%.
[7] | Although the Group has a significant influence with ownership percentage more than 50%, the contribution was classified as investments in associates as the Group is not exposed to variable returns due to the payment guarantee for the entire investment amount.
[8] | Although the ownership percentages are more than 50%, the Group applies the equity method accounting as the Group does not have an ability to participate in the financial and operating policy-making process.
[9] | As a managing partner, the Group has a significant influence over the investees.
[10] | The rate of Group’s voting rights is 19.86%.
