The revised Commercial Act, which includes provisions such as expansion of directors' duty of loyalty, has been in effect for one year. Over the past year, changes have been made to the business environment in companies, such as strengthening the review of board agendas and expanding external advice. However, the burden of lawsuits on companies also appeared to have increased. On the 12th, the Korea Chamber of Commerce and Industry announced the results of a survey conducted on 300 listed companies, ‘One year since the revision of the Commercial Act, changes in the business environment and support tasks for system establishment.’ According to this, 84.3% of responding companies said that there had been changes in the way the board of directors operates after the revision of the Commercial Act. The most important revision that brought about change was the expansion of the scope of directors’ duty of loyalty from ‘the company’ to ‘the company and shareholders’. With the legal basis for minority shareholders to sue when companies make decisions that go against their interests, companies have become more cautious when setting board agendas or making decisions. Regarding changes in the way the board of directors operates, 47 responded that ‘in-house inspection procedures, such as prior review by the legal and compliance team, were newly established and strengthened.’
