최대주주 변경유형이 신용평점 및 주식수익률에 미치는 영향

[Purpose] This study investigates the relationship between the change type of the largest shareholder of a company and credit rating and stock yield. Specifically, the study subdivides the types of the largest shareholder turnover into the number of changes, whether managers are replaced concurrently, whether the shareholding ratio increases after the shareholder turnover, third－party allocation among the reasons for the change, and whether or not to change to a corporate shareholder. After that, the study analyzes the relationship between the type and economic performance of creditors and investors, such as credit score and stock yield. [Methodology] The sample is based on 1,113 listed firms－years that have disclosed the largest shareholder change over the nine years from 2011 to 2019 after the introduction of the Korea International Financial Reporting Standards. [Findings] As a result of the analysis, CEO turnover, the increase in the shareholding ratio of the largest shareholder after the change, the change of largest shareholder by third－party allocation, and the change of the largest shareholder to the corporate shareholder showed a significant negative relationship with the credit score. Also, the increase in the stake of the largest shareholder and the change of largest shareholder by third－party allocation showed a significant negative relationship with the abnormal stock return. These results suggest that creditors and investors discriminately recognize the risks of the largest shareholder turnover, which could impair business stability, by classifying them by type. [Implications] This study presents implications for capital market participants and supervisory authorities by suggesting that the largest shareholder change, which is known to have high investment risk, has different risks for each type.
