In this paper, we investigate how the ownership structure of a firm is related to its corporate policy on payouts. Previous literature has identified several goals that may guide firms’ payout policies such as signaling firm value or lowering agency costs. Some of these studies argue that firms may distribute their cash or engage in share repurchase programs in order to send a signal to the market that either they are undervalued or their future value will be higher. Other researches claim that firms might lower their agency costs by adopting a payout policy to lower free cash flows. The focus of our study is to investigate whether the ownership and the control rights of controlling shareholders are linked to corporate payout decisions. It has been widely recognized that there can be a discrepancy between the ownership rights (also known as cash flow rights) and the control rights of controlling shareholders. In the case of Korea, ownership by affiliated firms can contribute to such differences. Many Korean firms have subsidiaries that are interconnected through interlocking ownership and internal capital markets. Considering the corporate ownership structure, we measure control rights through all the cash flow rights of controlling shareholders and the voting rights of all subsidiaries. Thus, the control rights include all the shares under the influence of the controlling shareholders. First, we examine payout policies for all publicly traded firms in the Korean Stock Exchange between 1998 and 2005. For share repurchases, we collected information on corporate decisions to engage in open market share repurchases as well as to allocate resources to trust funds that specialize in treasury stocks. Since all publicly traded firms are required to disclose their decisions on share repurchases, we collect information on the announcement dates, the amounts, and the methods of share repurchases. In addition, for corporate decisions to distribute cash to shareholders, we use the annual information of cash dividends reported in their financial statements. We empirically test the determinants and effects of payout policy using the announcement information and the financial data of publicly traded firms. Based on empirical results from previous studies, we have controlled for other explanatory factors such as firm size, capital structure, volatility, market to book ratio, cash holding, free cash flow, and chaebol dummy. In addition to these explanatory factors, we also examine how ownership and control rights affect payout decisions. Overall empirical results in this paper can be summarized in three parts. First, we find that firms of which controlling shareholders have greater ownership and control rights are more likely to choose to pay cash dividends to their shareholders controlling for other factors. In contrast, firms with lower ownership and control rights are more likely to adopt share repurchase programs. These results are strong and statistically significant. Thus, our findings support the hypothesis that ownership structure affects corporate decisions to adopt payout policy. Second, we test whether firms with weak ownership rights are engaged in larger scale share repurchase programs. Specifically, we examine factors affecting the number of shares that a firm buys back or the proportion of firm resources allocated buying back shares. After controlling for the aforementioned explanatory factors, we find that firms with weaker ownership and control rights are more likely to both buy more shares and spend proportionately more resources, compared to firms with stronger ownership and control rights. Third, we examine the effects of payout policy on firm value. In particular, we investigate how announcements by firms to buy shares affect their stock returns. Under the efficient market hypothesis, investor decisions in the market are believed to reflect all information available in stock prices. Thus, the changes in stock prices reflect how the market evaluates the payout decisions of firms. We find that stock prices decline after the announcement of share repurchases by firms whose controlling shareholders have weaker ownership. This result is different from the positive stock returns shown in many earlier studies of share repurchases that did not examine ownership structure. Our result suggests that investors in the market perceive a negative consequence of share repurchases by firms with weak ownership structure and consequently, firm value declines. Taking into account all the results in this study, we conclude that a firm’s payout policy depends on ownership structure. Moreover, firms with weak ownership structures tend to adopt share repurchase programs at the cost of other shareholders.

본 논문은 소유지배구조가 기업의 자사주매입결정과 현금배당에 미치는 영향을 실증적으로 분석하고자 한다. 1998년부터 2005년까지 상장기업을 대상으로 자사주매입에 대한 공시자료와 현금배당 자료를 이용하여, 지배주주의 소유지분율과 지배권이 기업의 지급정책에 미치는 영향을 분석한다. 지배권은 지배주주의 소유지분에 계열사의 지분율 등을 합한 지분율로 지배주주가 영향력을 행사할 수 있는 지분율을 의미한다. 분석 결과, 지배주주의 소유지분율이 높을수록 기업이 현금배당을 실시할 가능성이 높고, 지배주주의 지배권이 약할수록 자사주매입을 실시할 가능성이 높은 것으로 나타났다. 자사주매입의 크기를 전체 발행주식수와 시장가치에 대비하여 측정하였을 때, 지배주주의 소유지분율이 적을수록 자사주매입 규모가 큰 것으로 나타났다. 또한 자사주매입 결정에 대한 시장반응을 측정한 결과, 지배주주의 소유지분율이 낮은 기업이 자사주매입결정을 공시하는 경우 주가수익률은 감소하는 것으로 나타났다. 이러한 결과는 자사주매입이 기업의 경영권을 위협하는 외부투자자로부터 현 경영진 또는 지배주주를 보호하는 역할을 한다는 가설과 일관된다.
