Korea adopted IFRS in full in 2011 to enhance accounting transparency of Korean entities and usefulness of their financial information as well as to maximise the value of domestic entities by improving their accessibility to global capital markets. There have been numerous analyses carried out on the costs and benefits of Korea’s IFRS adoption, however, so far they were conducted exclusively from the users’ point of view. The Korean Accounting Standards Board (KASB) has now made available research into the costs and benefits from the preparers’ perspective.
