Abstract

Firms employ one of two stock repurchasing methods, either direct open market repurchase or indirect repurchase through trust contracts. Since these two methods have some regulatory differences, managers of firms may use a repurchasing method as a signal to convey the information to the market. Therefore, this study investigates the relationship between stock repurchasing methods and implied cost of equity of firms. The results show that there is a significant and negative relationship between stock repurchase announcement and cost of equity. In addition, the implied cost of equity for firms employing direct open market repurchase is significantly lower than those of firms that use indirect repurchase method. Overall, the market accurately reflects the information conveyed by two stock repurchasing methods into cost of equity of firms.

기업은 자기주식을 시장에서 직접 취득하는 방법과 신탁계약을 통한 간접 취득방법을 선택할 수 있는데, 두 방식에는 제도적인 차이가 존재하며, 따라서 자기주식을 취득하는 두 방식은 시장에 서로 다른 신호를 전달할 수 있다. 본 논문은 자사주 매입 방법과 추정자기자본비용(ICOE) 사이의 관계를 실증적으로 분석하였고, 연구의 결과는 다음과 같다. 첫째, 자사주 매입을 공시한 기업의 자기자본비용이 자사주 매입을 공시하지 않은 기업의 자기자본비용보다 통계적으로 유의미한 수준에서 낮게 나타났다. 이 결과는 여유현금흐름가설이나 자사주 매입이 체계적 위험과 투자지출의 감소에 따라 자기자본비용이 감소한다는 주장과 일치한다. 둘째, 자기주식을 직접 취득한 기업은 간접 취득한 기업에 비해 통계적으로 유의미하게 낮은 자기자본비용을 가지는 것으로 나타났다. 이러한 결과들은 시장참여자들이 서로 다른 자사주 매입 방식이 가지는 융합적 신호효과를 정확히 판단하여 이를 자기자본비용에 적절히 반영한다는 것이다.
