This study considers an important aspect of corporate governance: the relationship between cash flow rights and dividend payout policy of listed family firms in Taiwan, an economy characterized by a predominance of family-controlled firms. Dividend payout levels are important because they are crucial to governing the firm and managing its investments. The empirical results show that at a low level of controlling families' cash flow rights, the threat to lose control at any time makes controlling families claim more in dividends. This yields a positive relationship between dividend payout and the cash flow rights of controlling families at this level. Meanwhile, at a moderate level of controlling families' cash flow rights, the entrenchment effect becomes more robust and creates a negative relationship with dividend payout. Finally, at the very highest level of controlling families' cash flow rights, excessive firm-specific risk again helps to again create a positive relationship. This nonmonotonic relationship between controlling family cash flow rights and dividend payout also holds for financially mature firms that have a high earned to contributed capital mix.
