1 | Sum of the interests owned by the Controlling Company and subsidiaries.
2 | Although the Controlling Company owns less than 50% of the interest in Nasmedia Co., Ltd., KTCS Corporation and KTIS Corporation, Millie Seojae, and GENIE Music Corporation, these entities are consolidated as the Controlling Company can exercise the majority of voting rights in its decision-making process at all times, based on voting patterns at previous shareholders’ meetings.
3 | Although the Controlling Company owns less than 50% interest in K-Realty Qualified Private Real Estate Investment Trust No. 1, this entity is consolidated by comprehensively considering the criteria for determining control, such as ‘power’, ‘variable profit’, and ‘relationship between power and variable profit’, rather than simply judging by the interests owned by the Controlling Company.
4 | The number of treasury stock held by subsidiaries are deducted from the total number of shares when calculating the controlling percentage interest.
