A. The business under Article 42(1) of the Commercial Act refers to a functional asset as an organic integration organized for a certain business purpose. The term "functional asset as an organic integration" refers to a functional asset as an organic combination of tangible and intangible property and facts with economic value, which constitute a business, functions as a source of profit, and the functional asset as the source of profit that is systematically combined as such, becomes an object of transaction, such as one goods.

Therefore, whether a transfer of business can be seen as a transfer of business is the same business activity as the transferor has been transferred with a functional asset as the source of revenue organized by the transferee.
