Explanation of facts and circumstances of sale or reclassification and expected disposal, manner and timing The Group has decided to sell some of the Premises and Equipment through internal consultation during the current year and classified the property as non-current assets held for sale. The assets are expected to be sold within 12 months, and those that were scheduled to be sold at the end of the prior year have been sold and removed. On the other hand, other assets that are expected to be sold as of the end of the current year are classified as assets that are expected to be sold within one year due to the possibility of being sold as buildings and land acquired through auction.
